Smartworld: Identity Profiling With Radio Frequency

Take your medicine
Julie Beal, Contributor
Activist Post

RFID, or radio frequency identification (also known as near field communication, or NFC) is used for wireless communication between devices, one of which is a transmitter and the other is a receiver. This involves the use of low frequency radio waves passing between the devices; it is in widespread use, although the impact on health is rarely alluded to. RFID is being used for a multitude of applications involving sensing and communication of information, especially ID verification using smart cards/phones, miniscule sensors known as smart dust, bodily implants, and product tracking.

There are already many well-established ID Management companies who are also using or advocating RFID and biometrics. These companies are heavily involved in the emerging global identity ecosystem (eg, the NSTIC program, the work of the ITU, and the European initiatives, including STORK), and include Accenture, IBM, Verisign/Symantec and Oracle. The industry has grown significantly and the trend looks set to continue – especially considering the heavy investment by leading corporations like Google, IBM, and Microsoft.

The smart card industry is playing a leading role in identity management, indicating that in the near future the public will expect to manage their digitised identity with extrinsic devices such as contactless cards and mobile phones.

In Denver, for instance, Auraria Higher Education Center recently decided to issue new contactless smart cards to students (over 43,000 of them), and to staff. The cards will control door access using RFID, and will even serve as Visa debit cards. The plan is to eventually integrate the cards with other applications for student services, including parking, meal payment, library checkout, event management, emergency incidents, and lab and recreational tracking.


Assa Abloy, and its subsidiary HID Global, have both been involved with the NSTIC throughout its inception. HID manufactures RFID tags for people/animal-identification, as well as for tracking products. HID recently shipped out further supplies of their “e-ID solutions” to supply over 150 million people with chipped passports/smartcards.

In due course, however, the problems caused by people losing their smart phones or e-passports, or having them stolen or damaged, will likely signal the need for further security, leading to the uptake of implantable devices, like the VeriChip. There are already problems with the Bring Your Own Device (BYOD) phenomenon – where employees connect with the computing system at work with their own phone, etc – which could be ‘solved’ by implanted chips and identity management.

Intercede is a highly successful company in the identity industry, and recently has developed a means of enabling smart phones to use NFC for logical and physical access control, as well as identity verification and attribute management. This method actually replaces the need for smart cards. It works even when the phone isn’t switched on, and claims to avoid ‘skimming’ of personal data held on the phone by necessitating the “conscious consent of the user”.

Arguments that the chip is liable to hacking, whether it be in a device, card, or implant, are being countered with the advance of a new technology which claims to make the communications between a RF chip and a reader secure. Active Identity has developed an open protocol called ‘Opacity’ which prevents wireless transmissions being intercepted.

The use of identity authentication devices has necessitated the use of passwords or biometrics to validate use of the device. The problem is that the devices can be lost or damaged, and passwords can be forgotten or stolen. But now computer scientists have developed a mobile system which provides strong authentication for personal devices – a small device which measures unique physiological signatures is worn on the wrist (as a watch, or jewelry) and will automatically detect the identity chip it is linked to, whether it be a chip in a phone, or one that has been ingested, or implanted. Currently, mobile phones and smart cards/passports are the main devices used to verify identity, but proving the right person is using a device has been fraught with problems. This system will prevent impersonation because biometric authentication of the person presenting the identity device is automatically provided at all times. The system works by measuring ‘bioimpedance’, which is claimed to be more effective than other forms of biometrics, such as fingerprint scans.

All sorts of RF technologies for ID management, from phones to implants, are part of a burgeoning industry, as evidenced by a comprehensive report released in July by UK-based firm Smither Spira; the ‘Ten-year Forecast of Disruptive Technologies in Personal Identification’ report,
provides exclusive forecasts of market technology adoption through to 2022, broken down by end use and identity control type. This brand new report identifies 25 technologies that are predicted to have major influence on the personal ID market in the next ten years. Technologies covered include security printing inks, biometrics, national identity registries, encoded taggants, high-resolution optical effects and geolocation. Each of the 25 technologies is explained, analysed and ranked based on the impact it is likely to have on this evolving industry.
Some of the subject headings in the contents list include:
  • body implanted chips;
  • a biometric civil registry;
  • a VeriChip implant;
  • contact lenses that act like a computer screen;
  • geolocation as a security feature in personal identification.
There is a steady increase in the use of mobile devices for access and control; more and more people are using their phones and smart cards for identity verification, as well as using a phone to pay for things by just waving it near to a ‘reader’. There is even new technology which allows people to use NFC to scan their smart meter and pay their electricity bill with their smart phone.

As the trend of using a mobile device for so many applications continues, and becomes the norm, people will start to consider it awkward to have to even bother to bring the device with them. Why risk it getting lost or stolen when you could get it popped under your skin in no time at all?

Those who decide to get an implant will be techies, geeks, and transhumanists, busy young professionals, the fashion followers and even the clubbers and ravers . and then the sheeple will follow. (Or perhaps some will find RFID dental implants more acceptable!) Since we’ve come to expect there to ‘be an app for that’, and for things to happen instantly, especially with technology, the idea may even be a thrill to some people. After all, we are being conditioned to see implants as acceptable: they are mainly being used for health reasons, but they could also be used, for instance, to track offenders, or as virtual payment devices, ‘secured’ with biometrics.

Meanwhile, the technology is advancing at a very fast rate. For instance, HID Global announced in April that it has developed a new manufacturing process which uses direct bonding technology to mount an antenna to a tiny microchip, which is smaller than the pinpoint of a needle (i.e., its surface is less than 0.3 millimetres square). This means that some of the world’s smallest integrated low-frequency (LF) chips ever produced can now be used for contactless ID applications.

Tracking the VeriChip

Implantable devices are subcutaneous, i.e., they are inserted under the skin, and then use radio waves to transmit and receive information. The first of these tiny devices, the size of an uncooked grain of rice, was the Digital Angel, produced by Applied Digital Solutions. There are now numerous applications for the technology.

In March 2000, Applied Digital Solutions, Inc. (ADS), an Internet communications services provider, acquired the Destron Fearing Corporation, which was a manufacturer of animal identification tags. A year later, Applied Digital announced their new product: the Digital Angel – this was the prototype of the personal identifier, but was the size of a wristwatch. Another year later, in April of 2002, the company began to publicise the VeriChip – they had managed to shrink the device so that it could be implanted, and used for medical identification. To demonstrate this, a wave of chipping took place and the chip was cleared by the FDA in 2004.

The Digital Angel was originally designed as both a tracking technology and an identity verifier. Peter Zhou, the company’s chief scientist at the time, and President of DigitalAngel.net, Inc. (a subsidiary of ADS), described the device as,
a connection from yourself to the electronic world. It will be your guardian, protector. It will bring good things to you ... We will be a hybrid of electronic intelligence and our own soul.
It seemed the VeriChip was successful until lawsuits were brought against the company and since then it has kept a low profile, with several changes of ownership and name. Like other RFID companies it is now focussing on the promotion of patient identification technologies, and other health applications.

In October last year, VeriChip used an “integration partner” to negotiate a deal to supply the Israeli military with implants for emergency response operations. Marc Poulshock, PositiveID's Vice President of Business Development, said,
We believe there are many important applications for the VeriChip and our associated intellectual property including next-generation identification and bio-sensing capabilities. Our partner is looking to help healthcare organizations, militaries including the IDF, and governments with their disaster preparedness and emergency response needs.
In January (2012), the VeriChip technology was acquired by VeriTeQ, thus adding to its range of implantable, RFID technologies for patient identification and sensor applications.

VeriTeQ also acquired the Health Link personal health record from PositiveID. The long-time champion of large-scale microchipping is Scott Silverman, who was the former Chairman and CEO of PositiveID and VeriChip Corporation, and is now the Chairman and CEO of VeriTeQ (PositiveID has retained an ownership interest in VeriTeQ). Silverman, a qualified attorney, has kept the VeriChip technology going throughout all of its business incarnations, from ADS to the Digital Angel Corporation, the VeriChip Corporation, the Xmark Corporation, PositiveID, and now, of course, VeriTeQ. He also ran NationalCreditReport.com (a subsidiary of the Steel Vault Corporation), before yet another profitable sale last Summer, although he remains Chairman of the Steel Vault Corporation, which is said to be a “premier provider of identity security products and services, including credit monitoring, credit reports, and other identity theft protection services”.

Anyhow, Silverman now owns and leads VeriTeQ, which has managed to come up with a unique patented healthcare system by marrying the VeriChip with bio-sensors developed by Receptors, LLC. The sensors are implanted into the body, and can then detect rates and levels of various biological processes; the microchip stores the information, which can be read by scanners. The GlucoChip implant, for instance, is able to provide feedback to diabetics on the levels of glucose in their body.

The device therefore combines three components: the VeriChip, the bio-sensor, and the membrane covering them. The chip is said to be passive so would not need a battery. However, it could easily become an active chip, with the advance of energy harvesting (see tomorrow's article: "Uberveillance") and other innovative power solutions such as the tritium-based betavoltaic power source released by City Labs, which can last 20 years or more without being recharged.

Active chips can transmit and receive RF signals. The “Embedded Bio-Sensor System” developed by VeriTeQ, together with Receptors, LLC, received a licence for the patent in January. The bio-sensing and communicating implant has now surpassed the capabilities of other biosensors because it will use a newly developed and patented semi-permeable, bio-compatible membrane.

VeriTeQ is making full use of this unique patented technology – they have produced a temperature-sensing microchip, which has a range of applications, for example in cancer treatment, and offers the chance to cut expenditure. Development of alternative biological sensors has begun, such as for monitoring the pulse, and providing statistical feedback on levels of oxygen, medication, and radiation. All will be combined with the new look VeriChip, so that the biological information can be read by a scanner, along with the patient’s unique identification number (UID). The system can be even be used just for identifying breast implants.

Silverman has been promoting the GlucoChip for several years now, but the rise of medical implants has led investors to speculate that VeriTeQ is due to make huge profits. An investor report by GreenBaron.com claims the company is massively undervalued: there are over 30 million diabetics in America alone and the market for all types of sensors is booming.

The report included an interview with Caragol, discussing the various products PositiveID/VeriTeQ have developed. (Caragol is also Chief Executive Officer of Steel Vault, Inc., and he donated the maximum of $2,500 to Mitt Romney’s election campaign last year.)

In June, it was announced that PositiveID look set to provide an embedded bio-sensor system to the DHS as part of their Biowatch program, to detect a biological attack, such as the release of anthrax spores. Northrop Grumman are also bidding for the contract, which is rumoured to be worth $5.7 billion, but investors are backing PositiveID, which has already developed an early warning system, under contract for the Department of Homeland Security (DHS), called ‘M-BAND’ (Microfluidics-based Bioagent Autonomous Networked Detector).

The company also has a subsidiary called MicroFluidic Systems (MFS), which has already received US $45 million in government and commercial contracts, with 29 patents or patents pending, according to a report on PositiveID by an investor who believes the potential for profits for companies involved in high-tech and biotech areas of warfare, such as the use of smartdust, is very high.

Green Baron describes MFS as a company which “develops sample preparation and biological detection systems. MFS began developing complex microfluidic systems to perform sample processing and purification for the Defense Advanced Projects Agency (DARPA). It then developed a similar system, including a thermal cycler for PCR analysis for the US Army's Edgewood Chemical and Biological Command (ECBC).”

VeriTeQ, through its subsidiaries and joint ventures, is gaining in power and influence, and the VeriChip has wormed its way into a variety of implanted devices. In 2009, for instance, the company signed an agreement with Medcomp to add the chip to ‘vascular access catheters’ for patients with kidney disease:
Medcomp will embed the VeriChip microchip in its vascular ports to facilitate identification of the port in a patient and proper medication dispensing. Because the microchips have been approved as safe to the human body, it could potentially be put in any device implanted in the body, making it a convenient method for tracking devices. 
After VeriChip is implanted in the device, and the device implanted into a patient, the chip can be scanned to reveal the unique identification number of the device and checked in a database.
Linking the VeriChip to biosensors is an alarming move, because the technology is being developed for an extensive range of applications. Most of these would be classed as either diagnostic or patient management solutions, which would be seen to offer a whole range of benefits, such as cutting down on hospital visits, and ‘preventing’ disease. For instance, graduates from Purdue University have developed a bio-sensor that they claim is able to detect cancer at the earliest possible stages, and could also be used to compile a personalised “inventory of proteins and DNA” which could be used to inform doctors when prescribing treatment.

The prevalence of medical implants which can provide feedback on physiological/biological state is indicated by the fact that there is now a large scale monitoring service available. In June (2012), Sorin SpA and Orange Business Services launched Smartview™, a system which monitors people with serious heart problems via an implant, called Paradym™. The system has been established across Europe, and promises to extend its reach globally, as part of an “e-health platform”, by adding data from the RFID implants to the health details filed for that individual. This is a blueprint for global e-health in the system of systems, for which e-identity is a crucial component, with the data forming a highly valuable asset class, as well as exposing the most intimate aspects of our real identities.

The most alarming development, however, is, by far, that theVeriChip is now in another bid to chip the nation: it would appear it came ahead of its time, but now the chip-readers are widely available, and the e-health architecture has been established, ready to receive the first batch of implantees. Time, as ever, will tell. Oh, and it’s not called the Verichip anymore: it is now described as,

VeriTeQ's Unique Device Identifier (UDI) implantable RFID microchip for humans is the world's first and only FDA-cleared microchip for patient identification”.

Take Your Medicine

Other companies are also developing implants for health applications. A company called MicroCHIPS, for instance, began trials this year of an implant for osteoporosis sufferers – the device delivers prescribed doses of a drug to the patient’s system when signalled to do so by a radio signal.

Remote monitoring of human health can also be achieved by swallowing a microchip - Proteus ‘Mindfulness pills’ are powered by stomach fluid, which acts as the electrolyte and were developed by Nancy Dougherty at NASA Ames Research Park. She has been working with a Californian company called Proteus to develop a product which will help patients comply with their medicine regime; they are to wear a patch on the arm which can tell when one of the microchipped pills has been swallowed, so patients will always know when to take the next one. The Proteus pills are ‘placebos’, i.e. they are not active drugs, just ingestible chips, so the patient will have to take one each time they take their regular medication. However, the company hope that one day all medicines will be chipped in this way.

Proteus plan to market their product, which they have called‘Helius’ , in the UK later this year, in partnership with Lloyds Pharmacy, following approval in 2010 by the European Union. In August, the Helius system was reported to have received FDA approval in the US. The Proteus pill contains a chip the size of a grain of sand – which indicates the potential for the chip to be incorporated into other products. We might even end up ingesting them inadvertently!

A Saudi team is said to have invented an implantable microchip which can be used for tracking via GPS, and is loaded with cyanide, which can then be triggered to release a lethal dose at a time chosen by the attacker. This story first came out in the press in 2009 when it was reported by Germany’s patent office that it had received the application in 2007, and it was expected the patent would be disallowed. However, another country may well have allowed the patent, or it could be made without a patent!

The story serves as an important reminder about the potential nefarious use of implants, because the technology exists to make these types of implant, or some equally nefarious alternative, a reality. They are already being used to track patients and to deliver remotely controlled doses of drugs. Ingestible chips are soon to be marketed for personal health monitoring, with the intention of chipping all pills in the future.

Rumours abound that implanted microchips can be used to track people using GPS. These rumours have been fuelled somewhat by a series of adverts proclaiming “the worlds First Implantable GPS Tracker” by Lightening GPS, the primary supplier of covert GPS tracking to military and law enforcement.

The general consensus on the Internet is that this appears to be a hoax. The same is said of some of Bob Boyce’s stories about his free energy inventions and his claim to have had 2 VeriChips implanted by an adversary, and later removed when he developed cancer. I can find no other evidence of existing implantable GPS, yet HID Global's ability to produce miniature antenna could make this possible perhaps, and VeriTeQ display it as part of the infographic shown below. For now, there are plenty of other ways to track someone’s geolocation!

Smart Dust

Even without implants, or mobile devices which can be scanned, the future looks set to fill even the air we breathe with smartdust. These miniscule computers are performing round-the-clock surveillance. These could one day become so widely distributed in our environment that they are even borne aloft in the air’; and there are suggestions that they could be “ingested or even implanted”.

Engineers at the University of Florida, working with DARPA, have combined biology and nanotechnology to create smartdust particles which can “move things around”, each particle working independently; natural proteins convert chemical energy into mechanical energy. Nanotech mimics nature.

It is certainly within the realm of possibility that future prototypes of Smart Dust could be small enough to remain suspended in air, buoyed by air currents, sensing and communicating for hours or days on end.

There are even proposals to use smart dust to create nano-robots to explore Mars using swarm intelligence; it is estimated that,
one release of 30,000 robots could cover thousands of square miles. Each robot would contain a nanoprocessor, an antenna for communicating with neighboring motes, a sensor for collecting data and an electrode-controlled shape-shifting polymer shell.
According to IDTechEx research in the new report "Wireless Sensor Networks 2012-2022", WSN will grow rapidly from $0.45 billion in 2012 to $2 billion in 2022. These figures refer to WSN defined as wireless mesh networks, which are self-healing and self-organising.

“I guess, doctor, that your electricity is stronger than my will” – Delgado takes control

Delgado pioneered the use of brain implants to control the behaviour of both animals and humans in a life devoted to researching the effects he could induce. He also came up with an early version of the cardiac pacemaker, as well as controlling drug-delivery using implants. His most famous experiment saw Delgado successfully stop a bull in his tracks during a bullfight, by stimulating the electrodes in the bull’s head with radio waves. He was particularly interested in how he could manipulate emotions, as well as inducing physical movement. His ideas live on in modern day neural implants; function creep inches humanity towards a new cyborg identity. Or at least, those who can afford it could choose to be ‘amped’. The potential for abuse of these brain chips is huge.

The links between RF devices, implants, and identity control have been obvious for many years, but the evidence shows that the threat of ubiquitous chipping is coming closer to reality. We are in the first wave of change, where implants for health reasons have become widely accepted. The next wave will stem from the use of biometrics for authentication in identity management systems (see parts 3 and 4). The final nail in the coffin will be the end of cash, in the transition to virtual currencies. Only implants with multiple biometric credentials will be deemed secure.

Part I

"RFID, or radio frequency identification (also known as near field communication, or NFC) is used for wireless communication between devices, one of which is a transmitter and the other is a receiver. This involves the use of low frequency radio waves passing between the devices..."

Not so much. RFID describes a set of devices which are used to identify or tag objects - people, animals, or assets. Some RFID devices do use NFC, these are also called h-field devices, and do not use radio at all. Other RFID devices use e-field communication, or 'radio'. RFID is not "used for wireless communication", it *uses* wireless communication, which is quite different. Not all radio devices are RFID; most are not. People tend to lump any communication technology they find spooky under the term "RFID", which is both inaccurate and misleading.

Most of the RFID you're likely to encounter does not have a transmitter on one side and a receiver on the other. It might be more accurate to say that the interrogator is both transmitter and receiver, and the RFID device itself is nothing but a receiver. In the case of passive inventory tags and most implantable parts, any you'd actually term "RFID", this is certainly true. The tag itself never transmits at all.

More, for any NFC device, no radio waves are actually used. The designs are optimized to eliminate the emission of radio waves as far as possible - NFC actually uses non-propagating magnetic waves. Passive E-field tags use radio, but are never implanted.

Communication with passive RFID parts, e or h field, takes place by some sort of load modulation or reflection changes. In the case of NFC tags, the interrogator emits sufficient power carried by a radio frequency magnetic field to activate the tag. The interrogator signals the tag by amplitude modulation of the field. The tag signals to the interrogator by throwing a load onto and off of the pickup coil, which the interrogator sees as a difference in its output drive. The tag doesn't transmit anything, and certainly doesn't transmit radio waves - NFC doesn't use it. An analogy might be a driver in a car signaling someone pushing the car by tapping on the brake.

For an e-field tag, the interrogator beams a radio signal at the tag. The tag stores some of this for powering up, then signals back by changing what amounts to the radar cross-section of the tag, varying its reflectivity to the interrogator's signal. Again, the tag doesn't transmit at all. An analogy might be shining a flashlight at someone, and having them signal back to you by using a mirror.

In neither case do passive RFID tags actually send out their own radio signals.

Part II:

"RFID is being used for a multitude of applications involving sensing and communication of information, especially ID verification using smart cards/phones, miniscule sensors known as smart dust, bodily implants, and product tracking."

Here's where "RFID" is sort of being lumped in with other radio technology when it's not really RFID at all. Smart cards are sort of on the border - they do provide identification but often also store data and may do some low level processing. Phones are not currently, in general, RFID, although they may soon begin to interface with RFID tags and pretend to be an RFID device for some applications. That will likely happen with the next generation of phones. "Smart dust" is an unfortunate appellation that doesn't really describe the devices - they're definitely not dust sized and below the size of sugar cubes tends to use laser links - you don't have room for an antenna anymore. It is NOT RFID. Implants like Verichip are definitely RFID, things like insulin pumps are not. Product tracking is RFID.


"...employees connect with the computing system at work with their own phone, etc – which could be ‘solved’ by implanted chips and identity management."

This is an issue - if you're using a phone, iPad, laptop or whatnot for secure access, how does the system know it isn't someone that picked the thing up when you left it at the restaurant? Or, more likely, pickpocketed it so they could get into your facility? A somewhat more definite way is to require you to have a serial number implant which the device can access to verify you're 'you'. Certainly the places where constant authorization is needed that I've been, it's been a chip in your access card or use of a CAC card, though. Some places require me to stick the CAC card in the workstation and leave it there (tied to me by a lanyard!) for the entire session. Even implanted serial number parts have their downside - they can be cut out of you. But most places where you'd need something like this have secondary identification - a passphrase or calculation you have to remember for the day.

Unless you're working at the NRO, most workplaces will probably avoid implants for something like CAC cards, and eventually some sort of biometrics, likely iris scanning.

part III:

"It works even when the phone isn’t switched on, and claims to avoid ‘skimming’ of personal data held on the phone by necessitating the “conscious consent of the user”."

What's funny is that even current "smart card" level NFC parts have the ability to require a button press or a finger on a contact pair on the card to enable it - it's just that it's never implemented. It's simple enough to put a membrane switch or a copper pattern on the card that one would have to put a finger on to enable interrogation.


"But now computer scientists have developed a mobile system which provides strong authentication for personal devices..."

Mostly these fall into ekg morphology sensors (the "Amulet") or bioimpedance sensors. Bioimpedance is so variable for a person over the course of the day that it has unacceptable false positive rates (your cite had 10% even with a 10 person sample), but even worse false negative rates - a glass of Brawndo and the electrolyte/hydration changes will grossly affect the bioimpedance numbers. Over time, weight loss or gain will also cause miscalibration, even wearing jewelry will throw it off. The EKG morphology detectors are less prone to false positives, but if you have a double cappucino or someone startles you, you won't be getting into your computer for a bit.

"...and will automatically detect the identity chip it is linked to, whether it be a chip in a phone, or one that has been ingested, or implanted. "

Not at all. The point of physiological signatures is that they are intended to replace the need for implanted serial numbers, although they do not do so very well. What you might have read about Amulet was that they were seeing the need to ensure that two medical patients with functional implants (like an insulin pump) did not swap amulets, so the device would verify that it matched the implant it was supposed to communicate with. If you've got an identity chip implanted, no need for signatures. If it's in a phone, it's not really identity as it could have been stolen.

"...which uses direct bonding technology to mount an antenna to a tiny microchip, which is smaller than the pinpoint of a needle..."

Sounds eeeevil doesn't it? Basically they're wirebonding a loop antenna to a smaller part instead of using little ceramic 'boards'. Look at the top of the article - that copper colored part is the antenna. It's a very fine wire wrapped around a ferrite bead. At the right/bottom you see a darker bit, that's where the chip part is now. The part side will become smaller. But the assembly will remain about the same size. Having a smaller IC is always good for cost, generally in power consumption as well. Also it's stronger in flex than an assembly with loose wires and wire-ceramic wirebonding. The article linked actually discusses using the volume gained at the part end to just make the antenna bigger and leave the overall size alone.

Part IV:

"A year later, Applied Digital announced their new product: the Digital Angel – this was the prototype of the personal identifier, but was the size of a wristwatch. Another year later, in April of 2002, the company began to publicise the VeriChip – they had managed to shrink the device so that it could be implanted, and used for medical identification."

This is a mistake you see a lot amongst non-technical CTers. The "Digital Angel" and the Verichip are two profoundly different devices. Digital Angel was to be a stripped out GSM cell phone with a bit of biomedical monitoring added. Verichip is a jelly-bean h-field serial number part. A world of difference.

"The Digital Angel was originally designed as both a tracking technology and an identity verifier."

And so it was - it's a cell phone without the outside bits. Cell phones have ESNs, there's your identity number, and they are inherently trackable by thecell tower system, with some GPS assistance any modern cell phone can report back your location. Anything a cell phone can do, with the display and keyboard and whatnot stripped off, you'd expect a Digital Angel to do.

None of that carried over to the Verichip. They're as different as parakeets and cheese. That's why Digital Angel was a wristwatch - it's an entire GSM phone.


"The chip is said to be passive so would not need a battery. However, it could easily become an active chip.."

It is passive. It has no battery. Betavoltaics provide miniscule levels of power. They're also not particularly tiny. You don't have much harvestable energy inside a body, other than motion. Heat requires a differential to extract power, which you wouldn't have. Glucolytic power cells also provide very little power, and again, are not small.

Tom Bedlam said...

Part V:

But the real issue is in transmitting and receiving from inside a person. The verichip is NFC. It doesn't transmit anyway. If you're proposing that "it could be made active", it doesn't make much sense. A load-signaling NFC part doesn't have a lot to do without an external interrogator. I assume what you meant was, you could totally chuck the verichip part of it and mate the sensors to some RF transceiver of some sort. However, the sort of energy you could get by harvesting motion or glucolysis is pretty minor, and no betavoltaic puts out much power, so you don't have a lot of energy available for transmitting. Worse is the environment. You are a sack of electrolytes. You are quite conductive. This causes a few problems. One, the db/meter path loss is severe going out of a person, so you lose a lot of the transmitted signal. Worse, it's as bad coming in, so if you try to interrogate an embedded RF device with a distant signal, you won't get very far. There is another really bad problem with the step change in impedance between free air and a person, which causes havoc with reflections and loss. This is why the vast majority of implanted devices do NOT use RF. They use NFC, which is all magnetic. NFC hasn't got path loss or impedance steps to contend with, but it also has a strictly limited range due to it being near field, and due to SINAD issues even trying to interrogate such a device at the edges of its near field range.

Another problem with RF devices implanted is the device size. Efficient transmission or reception of RF requires an antenna that's closely related to the wavelength employed. If you want a small antenna for an implant, you have to use a very high frequency. However, the path loss due to dissipation goes up dramatically as the frequency goes up as well, which is a losing sort of game. NFC parts don't have the antenna size-frequency relationship issues, another point in their favor.

There are some RF-implant communication systems, notably MICS, which use a 400MHz band where there's a relative "window" in the frequency vs dissipation loss curve of the human body, however, that's relative - there's still a 45dB or worse loss from just subcutaneous to free air in the MICS band, which limits the range of MICS systems to a few feet.

"Northrop Grumman are also bidding for the contract, which is rumoured to be worth $5.7 billion..."

While it's not clear why linking verichip to anthrax is relevant, other than the 'yuck' factor, there are a number of bio-sensor systems in place even now to detect spore release. A common method is by using Mie laser detectors. These are all over the US. You just don't see them because you don't know what to
look for. There are other detectors you also don't notice that do little culture growth tests all the time, fully automated. Very interesting.

Microfluidics detectors are just another way, like MEMS/antibody sensors, to do the same thing. A microfluidic sensor would be faster than a culture type, not as fast as a MEMS/antigen type, but with a wider detection array.

Yates at your smallcap network cite gets it wrong - smartdust is not biological at all. He misread the Weinberger article he was using as source material, so there's not really any sort of link between PositiveID and smartdust through the microfluidics department.

I actually hope NG gets it, btw.


"...is indicated by the fact that there is now a large scale monitoring service available."

Sorin actually makes pacemakers, for the most part, and the Paradym RF line is just that. It's a pacemaker, not an RFID implant per se. All pacemakers have some sort of monitoring, testing and reprogramming communication link. Usually it's an NFC link. In this case, Sorin have made it a short range RF link ala MICS, which communicates with a bedside terminal. The terminal downloads pacemaker activity and monitoring data, which the Sorin units do especially well, then the service sends out optimizations to your pacemaker.

One hopes they have some sort of protection.

Part VII:

"The Proteus pill contains a chip the size of a grain of sand – which indicates the potential for the chip to be incorporated into other products. We might even end up ingesting them inadvertently!"

You missed the part where the chip size is not the system size. You need an antenna. That's not on the chip. The antenna is relatively large. In the medicine monitoring system, the antenna is the capsule, or the capsule is the antenna, depending on your viewpoint. The antenna is digested shortly after consumption at which point the capsule ceases to operate.

"A Saudi team is said to have invented an implantable microchip which can be used for tracking via GPS, and is loaded with cyanide, which can then be triggered to release a lethal dose at a time chosen by the attacker."

Hoax. Anyone can file a patent for anything. In the US, unless its obviously wrong (and I mean obviously) or if it's a perpetual motion device, it will issue even if it has no technical merit. You don't have to demonstrate it. German patent law is similar - you don't have to prove anything, other than non-duplication and non-obviousness.


"These rumours have been fuelled somewhat by a series of adverts proclaiming “the worlds First Implantable GPS Tracker” by Lightening GPS, the primary supplier of covert GPS tracking to military and law enforcement."

Another one. Call them - you'll note the page has no link from the rest of the site and the link for more information is always down. Or you could call them and ask. Seriously - implanted GPS has so many technical issues it's not worth thinking about, or listing here.

"The same is said of some of Bob Boyce’s stories about his free energy inventions and his claim to have had 2 VeriChips implanted by an adversary..."

Another hoax. I faced him down with some horrible inconsistencies in his story and he melted down. Hint - NFC parts do not emit a radio signal. The device he says he used to detect a verichip wouldn't detect one if you shot it into the thing with a rifle. The problem is - he didn't know how NFC worked.


" I can find no other evidence of existing implantable GPS..."

Nor will you, except as a gag or intentional hoax. I particularly liked the Empire North GPS sniper rifle. Even after they admitted it was an exercise to see how much attention they would draw (a worthy story in its own right), people still believe it's real.

"It is certainly within the realm of possibility that future prototypes of Smart Dust could be small enough to remain suspended in air, buoyed by air currents..."

Except at present, it's more like smart sugarcubes, with a desperate attempt at making smart rocksalt. If you actually read the paper you cite, you'll also see that smart dust as small as you envision will have to skip out on radio links altogether.

Thank you for your history of the verichip up until now. I really appreciate the summary which can be helpful in explaining the serious consequences to anyone willing to listen.
