Social Consequences and Effects of RFID Implants?
kramdam asks: "Even with all the talk about privacy and security, there seems to be a growing community of people who are implanting themselves with RFID chips. Being a developer myself, I am intrigued about building applications and solutions that will open my doors, unlock my car, log me on to my computer and control home automation. I'm seriously considering jumping into this head first, being on the bleeding edge, and going with an implant. I have looked at resources like Mikey Sklar's site, and Amal Graafstra's site, since they are two pioneers on this subject. For research, I have started TaggedLife to document my own journey. I was wondering what the Slashdot community think about this. What do you think are the social, security, privacy, and health risks associated with this? What are the pluses? Would you do it?"
Inplantable RFID tags are just not for me. Sounds a little to, well, end-times-ish. I would rather have an RFID watch or something. Sure, it could be stolen, but what about a central control website where if it was stolen, I just deactivate the code from it and put in the code for my new watch. Problem solved.
However, let's assume that this person WANTS the most high-tech solution imaginable. RFID tags are dumb devices with no meaningful logic, which means you can't do encryption key negotiation - or, indeed, any form of encryption at all. Anyone with a scanner can lift ALL of your keys with a simple RFID reader and can then impersonate you with impunity with ALL electronic devices.
If someone wants an implant - genuinely, truthfully, absolutely would die without one - then they should implant an intelligent device, preferably a small embedded general purpose computer. General purpose? Yes, then you only need one implant, which you can then program for ALL of your devices you want to control, rather than having one implant per device.
Strong, crypto would utterly defeat the RFID attack on cars mentioned in an earlier Slashdot story. It would also make the computer "unscannable" the way an RFID tag is, because it's no longer just a passive device. Further, an intelligent device could do ANYTHING you wanted, whereas an RFID tag could not. An embedded computer could monitor your temperature and control the thermostat accordingly, for example. An embedded tag could do nothing more than get crushed as the blood vessels expanded.
Personally, I would avoid implants. Implants can be thought of as deliberate splinters or deliberate cysts, depending on size. Both of these, when they occur naturally, can potentially turn nasty. The body really doesn't take kindly to foreign objects, if it detects them. When you've any kind of device that was probably not assembled in a clean-room environment, sterilized and completely clensed, there's a good risk that implants could carry unwanted hitchhikers. Even when it's all done properly, a good bruise near the implant could turn nasty. That's ignoring any chemical reactions between the implant and the body, which may have other unexpected consequences.
(You should also be aware of materials used. Materials that have a higher-than-normal level of alpha-particle emitters could seriously screw things up. The skin is thick enough to absorb alpha particles, in typical real-world conditions, which is just as well - soft tissue tends not to react too well to such things.)
The embedded computer shares ALL of the health problems of an RFID tag, though scaled up because it is more complex and involves more components. It also needs a power source, so you'll occasionally need to rip yourself open to replace the lithium batteries.
Now, there ARE ways to embed a computer in a person in a way that would minimize hazards on a day-to-day basis. However, there you're talking major surgery for the implant plus for each recharge. Surgery is, itself, extremely dangerous and not something you'd normally do just to add a gadget to your life.
It's possible to imagine surgical implants that COULD be recharged with less effort - such as enlarging the skull and using some of the space added, with a power outlet the bone can grow around - but we're talking serious sci-fi medical techniques here. Sure, there have been experiments involving wiring EEG devices directly to the human brain. Sure, even Stone Age medics could drill holes large enough to run a power outlet or an ethernet port. Sure, there are societies even today that deliberately reshape the skull. But to combine all of this AND enlarge an adult skull, not just reshape a child's... That is probably too complex for existing technology.
However, were implants to be a useful thing for society as a whole, a deep implant (such as in the chest cavity - if you can staple a stomach in half safely, you can wedge a matchbox-sized motherboard in there with absolutely zero impact), or a skull implant would seem to be far more resistant to damage, far more powerful, far more useful, far less toxic and far less likely to trigger an immune response.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
