Innovative Uses of RFID Tags 267
Roland Piquepaille writes "When your newspapers write something about RFID tags, it's almost always about Wal-Mart or how these tags are threatening our privacy. But they often miss the important innovations brought by this technology. For example, in Florida, RFID drives highway traffic reports on more than 200 miles of toll roads. Or take DHL, which is tracking fashion with RFID tags on more than 70 million garments in its French distribution center. Elsewhere, in Texas, 28,000 students test an e-tagging system which promises better security for them. And what about RFID tags which could prevent surgical errors and have just been approved in the U.S last week? So, what do you think? Are these innovations promising a better future for us or not? For your convenience, this overview contains the essential details from the different articles mentioned above."

First of all, there are two kinds of RFID chips, the active kind, that contain a power source and constant transmit and the passive kind that only activate when they are around the reader.
Most of the tags in existance today are passive models, they are cheaper and have a virtually unlimited lifespan. They are powered by either a electric or magnetic field (depends on unit frequency). These models DO NOT CONSTANTLY TRANSMIT and would be unlikly to cause any problems to humans unless they were read a lot (1000+ times a day).
The active kind are unlikly to be used alot around humans do to cost. The battery installed into them means that they usually only have a lifespan of around 5 years, and would have to be replaced then. Chances are after a cycle or two of battery usage, whatever the tag was doing will be replaced by a better technology.

I'm in a university society called the Assassins' Guild [ucam.org], which is a cross between roleplay and live-action Quake Deathmatch. The game we play involves hunting down other people playing the same game until only one is standing, and is cooler than it sounds (hey, we have girls playing!). The thing that's interesting with respect to this discussion is the excellent testing ground this gives for new technologies vis-a-vis the tracking of indivisuals.
Number one on the list is, surprisingly, static IP addresses on home-user machines. If you know your target's IP address, it is trivial in many cases to check whether he/she is in his/her room, and secondary information like lecture times (and hence the target's course) can be inferred.
On a more sophisticated level, it is possible to examine the movement patterns of a target by the public workstations he/she uses (they have to be regulars on the #assassins IRC channel for this to apply), although this is more easily maskable using screen/irssi off a unix server. The holy grail would be to scan the mobile phone command frequency band - one would only need to know one's target's phone number to triangulate his/her position. I don't know of anyone who's done this, but I'll be attempting it myself over the holidays.
RFID tags present an issue at a similar level, albeit with far greater possibilities for abuse due to their small size. If I were to have access to a reader (of the sort that, if this technology were to become widespread, would be available with no hardware hackery required), I would wait til the target were dumb enough to leave something outside his/her door and drop a suitably crafted tag in it. This would enable me to trail and ambush the target fairly easily when they didn't have any means of defense to hand.
This would be a slightly overworked solution for the purposes of the guild (albeit an excellent way of dealing with one of the more skilled assassins) but would come into its own in the hands of an actual stalker. Imagine someone you can't flee, can't hide from. Imagine what could happen if this technology were abused.

Of course, by "no laws", I don't mean the usual blend of common law and a few odd state laws that protect everything from letters to phone calls to internet, etc. What I mean is that the only "privacy protection" you now have on the internet is that there is no feasible way to track each packet from users of interest. In other words, you have some privacy because your traffic gets lost in a sea of user traffic, and there's no easy way to fish out just yours across sessions.
If P-III ID tags were enabled, the enormous processing power and computational state it would otherwise would require to track individuals would be eliminated. Transactions would be tracked across sessions. Now, that's a key term: "across sessions". Just what do I mean by it? And why is that so important?
Consider, for example, that the police can observe your car on the street, and by consulting a computer, the cop will know it's your car, where you live, etc. But there's no way for the police to also know that 2 weeks ago, you were at the same intersection making a left. And that 34% of the time, you instead make a right. And that you usually blow through the light at 30MPH, even if it's raining. Your driving sessions are not tracked and correlated across sessions. The cop can see you just this instance, but we don't expect that we live in an old East German state where every little action gets recorded and reported to some authority.
Similarly, on the internet you can visit a web page and (if you remember to flush your cookies and use DHCP), there's no easy way for the site to tell that it's you again.
The key idea is that in accumulation small pieces of information add up, and infringe on a piece of liberty that we all hold dear: privacy. We reasonably expect that our actions, although observed and perhaps inspected in a given instance, are not tracked and correlated with all our previous actions.
So, while you think the P-III unique ID was a cool technical idea, it in fact was:
Consider that if a corporation tracks every piece of individual information you "leak" throughout the day, it's called market research. But if an individual did this to another individual, it's called stalking .
So, be thankful for us "privacy types". We and others see these social problems not as black and white, and perhaps a little grey, but as the complex hues they really are.
