“…a few hundred meters away….”
Forget RFID. Well, don’t, but National Scientific Corporation has a prototype of a WiFi tagging system that, like RFID, lets you track things in real-time and space. The advantage that the WiFi Tracker system has over passive RFID tracking is that you can keep tabs on objects with WiFi Tracker tags (which can hold up to 256K of data) from as far as a few hundred meters away (the range of passive RFID taggers is just a few meters). While you can do something similar with active RFID tags, with WiFi Tracker companies can use their pre-existing WiFi network to track things rather than having to build a whole new RFID system.
In other news, Apple is adding WiFi to the iPod.
And, of course, you can be tracked from your cellphone:
But the FBI and the U.S. Department of Justice have seized on the ability to
locate a cellular customer and are using it to track Americans’ whereabouts
surreptitiously—even when there’s no evidence of wrongdoing.
A pair of court decisions in the last few weeks shows that judges are split
on whether this is legal. One federal magistrate judge in Wisconsin on Jan.
17 ruled it was unlawful, but another nine days later in Louisiana decided
that it was perfectly OK.
This is an unfortunate outcome, not least because it shows that some judges
are reluctant to hold federal agents and prosecutors to the letter of the
It’s also unfortunate because it demonstrates that the FBI swore never to
use a 1994 surveillance law to track cellular phones—but then, secretly,
went ahead and did it, anyway.

The Hymn Project exists to break the iTunes mp4 copy-protection scheme, so you can hear the music you bought on any machine you want.
The purpose of the Hymn Project is to allow you to exercise your fair-use rights under copyright law. The various software provided on this web site allows you to free your iTunes Music Store purchases (protected AAC / .m4p) from their DRM restrictions with no loss of sound quality. These songs can then be played outside of the iTunes environment, even on operating systems not supported by iTunes and on hardware not supported by Apple.
Initially, the software recovered your iTunes password (your key, basically) from your hard drive. In response, Apple obfuscated the format and no one has yet figured out how to recover the keys cleanly. To get around this, they developed a program called FairKeys that impersonates iTunes and contacts the server. Since the iTunes client can still get your password, this works.
FairKeys … pretends to be a copy of iTunes running on an imaginary computer, one of the five computers that you’re currently allowed to authorize for playing your iTMS purchases. FairKeys logs into Apple’s web servers to get your keys the same way iTunes does when it needs to get new keys. At least for now, at this stage of the cat-and-mouse game, FairKeys knows how to request your keys and how to decode the response which contains your keys, and once it has those keys it can store them for immediate or future use by JHymn.
More security by inconvenience, and yet another illustration of the neverending arms race between attacker and defender.
