In the category of unbelievably bad ideas that we all knew were making their way toward reality whether we like it or not comes the news the FDA has just approved VeriChip's implantable RFID chips for use in humans. These are the same chips that we're currently using to identify our pets. VeriChip is touting the chips' medical applications, as a way of potentially saving lives by storing medical data.
Silently and invisibly, the dormant chip stores a code — similar to the identifying UPC code on products sold in retail stores — that releases patient-specific information when a scanner passes over the chip. At the doctor's office those codes stamped onto chips, once scanned, would reveal such information as a patient's allergies and prior treatments.
The FDA in October 2002 said that the agency would regulate health care applications possible through VeriChip. Meanwhile, the chip has been used for a number of security-related tasks as well as for pure whimsy: Club hoppers in Barcelona, Spain, now use the microchip much like a smartcard to speed drink orders and payment.
In case it's not immediately obvious to you why you wouldn't want to walk around in public broadcasting your financial and/or medical information to anyone with an RFID reader, Bruce Schneier spells it all out for you in a great post on the Bush administration's
plans to push for RFID-based passports. Here's a nice chunk of it, but you should read the whole thing.
These chips are like smart cards, but they can be read from a distance. A receiving device can "talk" to the chip remotely, without any need for physical contact, and get whatever information is on it. Passport officials envision being able to download the information on the chip simply by bringing it within a few centimeters of an electronic reader.
Unfortunately, RFID chips can be read by any reader, not just the ones at passport control. The upshot of this is that travelers carrying around RFID passports are broadcasting their identity.
Think about what that means for a minute. It means that passport holders are continuously broadcasting their name, nationality, age, address and whatever else is on the RFID chip. It means that anyone with a reader can learn that information, without the passport holder's knowledge or consent. It means that pickpockets, kidnappers and terrorists can easily--and surreptitiously--pick Americans or nationals of other participating countries out of a crowd.
It is a clear threat to both privacy and personal safety, and quite simply, that is why it is bad idea. Proponents of the system claim that the chips can be read only from within a distance of a few centimeters, so there is no potential for abuse. This is a spectacularly naive claim. All wireless protocols can work at much longer ranges than specified. In tests, RFID chips have been read by receivers 20 meters away. Improvements in technology are inevitable.
Do you really want to walk in and apply for a job knowing that you're broadcasting details about a heart condition/HIV infection/cancer history/etc. to everyone within 20 meters, including the people who are considering whether or not to hire you and pay your medical insurance and sick leave? Do you really want to walk down a crowded street broadcasting financial data of any kind to God knows who? Is it really a good idea to broadcast personal identification information to anyone and everyone, when identity theft is one of the country's fastest growing crimes?
All "Mark of the Beast"-type stuff aside, this makes about zero sense from a security and privacy perspective. You can make all the tinfoil hat jokes you like, but I'm with Bruce Schneier in concluding that the only use for this technology that makes real sense is what Wal-Mart wants to use it for by putting it on their products, namely surveillance and tracking.
