Arizona: Pilot program may track schoolkids with RFID bracelets

[Quaamik]

Oh, well. If it happens here, I suspect my daughter will break a lot of them. It won't be implanted, and if so, I suspect she'll enjoy experimenting with high voltage stun guns.

Same here, and I'll get to tech my daught tricks of the testing trade at the same time.

In my job, I get paid to find new and interesting ways to break things.

And I already referred to the big problem of RFID implants over on the "I'd get an RFID thread if..." thread. You'll note my conspicuous non-answering of the original question...

Yep. Millions of little "bricks in the wall". They are too late to get most of us, but we'd best be vigillent of our children, and teach them to be vigillent of theirs.

Dang, couldn't you find SOMETHING we could argue about?

And madmike responded:

Um, I hate Garands, love ARs, despise Berettas and think old Mausers are better with sporter stocks.

Oh, and 870s are WAAAY cooler than Mossies.

Daaaang friend. You DO got out of your way to honor a request, don't you?

D6,

Certainly no one would think of using encryption on the RFID data.....

Same here. Only I don't get paid for it. And it's not really my job. It's just one more QC service I offer to the public.

"Certainly no one would think of using encryption on the RFID data....."

Oddly enough, very few have. Or if they do, it's usually pretty weak. By definition the master key has to be somewhere, and the more of the output data the end user knows or can know (name, serial, et. all) the easier it is for them to permutate the key from it.

In the case of an RFID system you're hosed both ways - You either store the key on the chip along with the encrypted data, in which case the user is walking around with the key all the time, ripe for the taking; Or, you store the master key on the server and do all the data transmission encrypted, with the caveat of there being only one possible key (because if you changed it you'd have to re-chip everybody...) and as soon as some joker learns that key your entire system is compromised.

However, even passive RFID can be rewritable. I could keep the new
master pw on the server and then change the chips by RF without
removing them. But, I think you're right that they wouldn't have to
be encrypted to serve their purpose.

Encryption would be a moot point since everyone would have a unique ID
that is registered and monitored by a central system. Try to clone one and
you get alerted. Drop off the system and you get alerted. Therefore, no
need to actually change it. You just encrypt it to a point where "dumb
criminials" can't briefly spoof someone and try to carry out purchases. I
think such a system could react fast enough to stop even the first
transaction except in the most remote of areas. In these remote areas
we're not talking BIG purchases but little stuff like at the convenience
store.

I think all of you will appreciate how a current tracking system works:

http://www.xora.com/timetrack/flash_demo.html

Just enter your info and you'll get a demo. It's long, but from the
first menu you can skip to the part on location tracking. It's talks
about the little GPS "breadcrumb trail" but my favorite section was
the "Exception Reports" and what happens if a user displays "unavailable
time."

Now you wouldn't really need a PHONE to do this, but a single RFID
device that could get pinged off of about any type of RF/net-connected
gateway already out there: celltowers, hotspots, wal-marts own rfid
tracker, other stores/kiosks, etc.

I would think the cellphones themselves could eventually do this for any
RFIDs nearby and boost those back to the closest tower.

Yep, this technology is here right now. But, sure, let's have the naysayers
chirp that I need to roll up in my tinfoil sleeping bag and take my meds.

Guess what... I work for a company that builds semi-conductor devices for RFID tags and we (not the rank and file but the stock-holders and upper managment) stand to make a LARGE fortune with this technology.

How much you want to bet that very soon it will be a felony to possess a firearm without an RFID chip on board and it will be a requirment for us to have a implanted RFID chip to own firearms... slippery slope.
