Streamlining and Testing RFID Technology 69

Multiple readers have written to let us know that an experiment at the upcoming Hackers on Planet Earth (HOPE) conference will use RFID to track the movements of at least 1,500 registrants for the duration of the conference. Those movements will be transmitted onto screens which "show in real-time where people go, with whom they associate, for how long and how often." The system will also be used for games which involve manipulation of the available data. Meanwhile, researchers at the Georgia Institute of Technology have developed a method for testing large quantities of RFID tags, which may serve to greatly speed distribution.

        Years ago at a roleplaying convention I participated in a Babylon 5 game where someone tried to plant a bug on Odo's back without him noticing.

        Odo subsumed the bug and caused it to work it's way down to his hand so he could then inspect it.

        Not particularly enlightening I know - but it was the image I had in my mind when I read the above comment.

    There's nothing that bugs me more with nascent technology than RFID. I don't mind it in products -- it would be great to inventory a warehouse, or, say a refrigerator, in minutes. Theoretically, I wouldn't mind RFIDs in identification cards, if it weren't so darned close to the skin. What really concerns me is RFID implants.

    It reminds me of the tattooing of numbers on Jews during the holocaust, for the Third Reich to track them and 'dispose' of them. I'm not a Christian, but the whole "mark of the beast" stuff raises my hackles. It just seems way too open to abuse for any totalitarian-minded politician. At first it's just for medical records, then it's for routine identification stops... finally, there's some computer screen somewhere in a mountain showing the movement of every American citizen.

    I don't know, I just have a very visceral reaction against the idea of an RFID implant. I have a phobia of needs; that might have something to do with it. If it really came down to the point where you had to have an RFID implant to participate in society, I don't know what I would do. I really don't. I might just drop out at that point, try to live in a cabin somewhere.

      Are you opposed in every case, or just "forced" implantation? I can think of several scenarios:
      • Required to enter secure room at work - (I believe this is in use in some places today)
      • Optional to enter secure room at work, with the alternative being a time-consuming strong password, a card swipe and a retinal scan
      • Optional as part of criminal home monitoring - either remain in jail or stay at home with an implant kept near the bedside monitor, instead of an ankle bracelet
      • Required to hold a particular job, such as prison guard
      • Voluntary temporary implant to hold credit information while you're partying on nude beaches (I heard some bars in Ibiza have done this, but I don't get out much!)
      • U.S. Army soldier, as an optional replacement for the Common Access Card - they get filled with vaccinations and all kinds of other stuff today, and are essentially treated as paid property of Uncle Sam.
      • As a voluntary part of a lifesaving medical treatment -- perhaps the tag is swallowed and followed through your GI tract, or perhaps it's implanted and used to monitor a medical condition?
      • As a required part of a lifesaving medical treatment, where your only access to obtain treatment is to consent to implanted RFID?
      I'm just wondering what your tolerance is. A similar question is: do you carry a cell phone? They're more trackable than an RFID chip. RFID is still limited to less than about 100 meters under perfect conditions. Or do you have to carry an RFID access card for work? Again, not a big difference in "trackability".

      As far as health, RFID is a low power technology, and active chips emit only a minute fraction of that power. The only real exposure you get is from RFID readers, not RFID chips. And you can't really avoid the readers unless you don't walk through the doors at stores with anti-shoplifting antennas.

      Anyway, I think the Xtian Right would rise up before they'd accept mandatory implants, so you'd probably have some strong allies there.

        You see, the thing is, I'm not really opposed to it at all. What I'm opposed to is its misuse by government. If it were totally and completely voluntary, great. I wouldn't have a problem. The problem is, I see the 'several scenarios' growing to a point where it's mandatory to have a chip from birth, or else you are an 'untouchable'. Sort of like a social security number -- who even knows what its original scope and purpose was? But nowadays, you need one for practically any serious financial transaction. Y

        • Why would you need an RFID chip for surgery? Why not a regular hospital bracelet? If you need definite identification, you can even get a temporary tattoo from a tattoo gun. If it's done lightly, it comes off in about 30 days.

          Not that I don't entirely agree with most of your points, there's a liability issue with patient identification. Hospitals spend a LOT of money trying to minimize human error when it comes to getting the right treatment to the right patient. The consequences of error can be severe for both the patient's health (long and short term) and the bottom line of a hospital's finances (due to malpractice litigation). As such, I am completely understanding if a hosptital wanted to demand that you had an RFID tag

          While they seem like adding fuel to the fire, the technology concerns you raise just aren't that big.

          RFID chips have no power source of their own, and are electrically inert until they're powered up by receiving energy from an external transmitter. Unless you have an actively transmitting RFID reader next to you, your tag won't be able to "modulate your nervous system" or do anything else to you.

            Correct me if I'm wrong, but isn't the external transmitter that activates an RFID chip simply a radio broadcaster? In that case, couldn't a radio or cell phone tower be repurposed, relatively easily, to 'activate' the RFID chips of an entire town?

            Or if you were some law enforcement agency or some governmental authority, couldn't you easily disable anybody with the proper RFID chip nested into their nervous system with the right kind of 'radio gun'? Just walk into a room, press a button, and the target is

        Putting them on military personnel? Not a chance, it would put your guys at an enormous tactical disadvantage when $50 worth of common electronic components could "light them up" from 100m.

        There's probably a few more reasons the government would not be interested in implanting such things in citizens. Cost of operations having to figure out how to install, maintain and monitor everyone. Considering no totalitarian group is doing this now, I think people in current democracies are pretty safe from this.

        As mentioned many times in the thread, there's already many other methods of tracking that's already usable by the government when they are interested in you. Hell, we can't even get a few miles of "electronic fence" to work at the border, I really don't see people handing over money for a project of this scale in my lifetime.

        For the guy who mentions "all but 7 RFID cards are accounted for" in a burning building and firemen go dying, I highly doubt firemen would go running into a burning building because someone might be in there over employee swipe badges. They tend to go on "Hey, Suzie was on the 2nd floor! I think she's still inside! We can't find her!" instead of waiting for the NT admin to run into said burning building, log into a Win2k machine that's off the network and audit who has come and gone from the building since the fire started.

      I agree, and the only place that I've EVER seen where RFID technology on people is appropriate is aboard a Federation starship or space station. Outside of a military situation... well, NATCH! Not worth the effort.

      Think of this in what I like to call the 'failure mode analysis':

      Your company (100-250 people) uses RFID tags. A fire breaks out. All but 7 people's RFID are accounted for. The FD goes in to the burning building to get them ... 2 firemen die. All 7 were in the parking lot watching at the time.

      It's absolutely no good for tracking terrorists.. they won't wear them and you won't have sensors to pick up the individuals that don't have RFID tags. This applies to any building currently in existence.

      You decide to tag everyone in a town of 3700 people for an experiment. After an estimated 430 million dollar installation of equipment, the sum total of what you know will be that people get paid on thursday and go to the bar. Walmart is busy on the weekends, and the guy you found cheating is suing you for illegal disclosure of personal information.

      Now, say you have a valid use for this, such as security in your data center, or so you think. Only people who have embedded chips can access the data center. There is a car crash, one tech dies, two are in hospital. Now your backup system is down over the weekend, and you can't even buy access to the data center. Yes, that might be a stretch, but I did say 'failure mode analysis'.

      Now, if you want to tag your milking cows to keep track of them, make sure they are getting milked, vaccinated, etc. That is useful. If you want to make sure that all the deliveries to your distribution center reach their intended end user space.. that also is good.

      Tagging people has a *VERY* limited use, no matter how cool it might seem. I'm always willing to be proved wrong though.

      At the conference, it might be cool to have anonymous RFID tracking to see what kind of data it would provide, but linking it to an individual would be wrong. If you want to see how the traffic flows through the booths, it would work but then so would cameras and video analysis software... hmmm I'm willing to bet that the video analysis would be much easier to implement, less intrusive, and much more reliable as there would be no swapping of tags, no RF interference issues, no expensive system to install for tracking etc.

      So, somebody tell me what I've gotten wrong here?
