    Well, you can tell by the way I use my walk

    that my cell phone’s on and it’s time to talk.

    Ring tones loud and texting warm; I’ve been wireless

    since I was born…..

    How interesting! I went looking for cell phone theft data for everyone’s favorite superhero, BayesMan, to use. No luck, but there is apparently an advocacy group on behalf of cell phone users. Assuming they’re legit, this is an encouraging sign in the privacy/monopolistic practices department.

    It’s amazing what cellphones can learn about their owners. See Ryan Siegel, When Cell Phones Become Oracles, Wired News, July 25, 2005, at http://www.wired.com/news/print/0,1294,68263,00.html . Eric.

    4% seems annoyingly high for a false negative rate. If it checks every hour, that’s once a day you have to key in your password.

    The technology reminds me of the signature-verifying technology for credit cards being worked on that doesn’t look at the image of your signature, but rather how you move the pen as you sign your name, which apparently is more reliable.
