Hacking the RFID Network
An anonymous reader writes "The world's largest retailers are developing the EPC Network as the infrastructure for a global rollout of item-level RFID. In many ways this 'Internet of Things' resembles the ISBN system or CueCat's codes-to-content. But the network built for tracking consumer goods could also be used for intangible items: airline seats, music tracks or service calls."
on overusing this new system
Track music downloads and service calls? That's billions of unique items every year. How many items do these RFID tags support?
I can track my porn collection internationally?
I knew they could be used as flotation devices- but now they're apparently virtual as well. That explains the problem with overselling flights I guess. They're selling VAPORSEATS (tm) (Patent Pending)

What they're saying is that RFID can be applied to intangible information - content rather than the physical media - just like ISBN/Library_of_Congress system uses an identifier for a book rather than an instance of it.
In other words: RFID can be extended to apply to an entire class, rather than instances of it, as is usually done.
Bet somebody'll mention how this is great for pr0n in the next 5 minutes.

The major shortcoming of RFID tags is not their rollout in stores, it's that they want to do things like weave them into clothing fabric or hide them so you've got to work to get them out. I don't know about you, but that's a bit excessive. Moreso, the range on the tags is an issue; the tag may be tiny, but you can still get a considerable amount of range out of that, look what's possible with GPS.
Then we've got the registering everything idea. If we put RFID tags on everything that can go for 100 feet, and if everything has a unique identification code, then the government can ask for a list of which codes are associated with which objcts. Then, as stuff is baught, you swipe through your drivers lisence and a database is updated with what you have. Combine this with bank account data, wifi hotspots on poles that are constantly pinging devices, garbage trucks equiped with rfid scanning technology, and other pieces of information, and you've got one hell of a spying system. All those evil laws the people in power dream of would be possible.
If there was a law that said the RFID tags could only be put on removable stickers, and must have a range limited to less than 5 feet, then it'd be ok. It's the "weaving them into products" thing that's got everyone upset. Infact, if that weaving thing didn't exist, I think RFID tags would be pretty neat; you could buy a bunch of food and query it through your house, which could download and update a database of recipe's which could be setup on some kind of whacky algoritm that figures out which is going to go bad first.
The only problem there is that as the chips evolve, we'll be throwing small flash cards on em with advertising or more complicated systems of ensuring produce hasn't been tampered with, which if the laws don't change, will require licensing since you're copying; licensing to eat, not a good thing.
AS far as tracking people is conserned, we all know of the mark of the beast, and we all know that tracking accounts with rfid tags is just plain stupid. If you're going to track a person, have them wear a wrist band or something; even the guys on star trek didn't have that little pin thingy embedded in their forhead.

i, for one, welcome our rfid tagged japanese overlords.
for a minute there, i lost myself...
If there's anything to say about the japanese, it's "wow, they're screwed up". If tagging your kid everywhere they go says something, it says "I don't trust you"; and the longer kids aren't trusted with responsability, the less they will be responsable, and if the world is filled with irresponsable people....
Dear lord...that'd be one screwed up place...

.. Are Japanese school children anyway? (Japan school kids to be tagged with RFID chips) Just wait until a stalker hacks that RFID network!
One line blog. I hear that they're called Twitters now.
It's my understanding that a common practice these days is to have microships (which I assume to be RFID tags) injected under the skin of pets, so lost pets can be identified even if they're not wearing collars.
I think a good idea would be to make pet doors that can "learn" to unlock only when certain RFID tags are within 4 or five feet. You could set it for the pets you own, and other pets (and/or other critters) wouldn't be able to get in.
Also, if your pets didn't have the chips implanted, you could just get a chip on a collar.

I'll let the philosophers sort out whether the ability to track every object is a good or bad thing. However, I do know that if this system becomes too pervasive without security, this is going to be a big problem in a hurry.
I remember a commercial where a shifty guy walks through a store stuffing things in his jacket, and then walks out of the door to be stopped by security. The guard informs him that he forgot his receipt, hands it to him, and sends him on his way. I'm all for putting checkers out of work, but if such an environment existed, it would also be profitable to spoof the system.
As they are currenly used, I suppose the only profit would be to either disable the tags or somehow make the store think it has already been purchased. That brings me to the next issue. I assume most people have tried to walk out of a store with a purchased tagged item where the checker forgot to take off the tag. It is annoying and embarassing. Imagine if this could happen with every article of clothing that you own because the store database gets screwed up.
I don't practice what I preach because I'm not the kind of person that I'm preaching to.
What would be the easiest way to find and/or destroy an RFID tag? Put your new pullover in the microwave oven for 3 seconds?
Is there any way to destroy such a tag embedded in electronics? Would it be possible to make the tag a vital part of the electronics in such a way that its destruction would lead to immediate equipment failure?
Are the signals easy to spoof?
Geek rants since like... 2000 or something.
Maybe I'm just spoiled being a hardware engineer, but it seems to me that the people who are crying about these RFID tags and privacy are just plain ignorant.
I can tell you it will be trivially easy to build a jammer for them. Maybe a little harder to build an RF source with enough energy to burn out their cute little itty-bitty diodes. And until they get wise and start putting challenge/responce encryption in them, building a box to spoof them would be a weekend project for your average Radio Shack hobbyist.
Will someone please educate them about the technology so they can devote their time to something that really matters? (If they want something to bitch about, they can read my blog for ideas.)
I might just wait until they're manditory in license plates and walk parking lots blowing them all out, (but probably not being a grownup and all.) Perhaps I should have posted as AC just for suggesting it. (Damned Patriot Act bastards.)
