Life Recorder
Bruce Schneier writes "In 2006, writing about future threats on privacy, I described a life recorder: A 'life recorder' you can wear on your lapel that constantly records is still a few generations off: 200 gigabytes/year for audio and 700 gigabytes/year for video. It'll be sold as a security device, so that no one can attack you without being recorded."
or wearing a disguise of any sort
MD is a 2 party consent state - can't use it here!
I'll just steal your "Life Recorder" after I beat you up. Thanks for understanding.
Good luck getting into a cinema wearing one of those.
How about a bicycle-ride recorder, for the next time someone throws trash at you or yells obscenities.
Oh, yeah, it's not easy to pad these out to 120 characters.
I sort of use something like this today, in the gritty old present day.
In my car I've got one of my old PDA's mounted instead of a GPS device. It's rather firmly permanently mounted to the dash until you take all the bezels off and unscrew it from the back, so I consider its risk for theft fairly low. Also, it's not mounted in the usual look-at-me GPS area but down by the driver's side kick plate.
Anyway, I have it there because I use Pocket Excel (don't laugh) to keep track of all my invoices and orders for the day. I also have a mapping program installed, and obviously it uses GPS. I've successfully used it to defuse two frivolous traffic tickets by less-than-scrupulous police officers: Once by making it a policy to keep all of my GPS logs, and once by happening to have a hotkey for the note taker "record" function bound, so I could easily and silently (also legally, in this state!) record everything the lying police officer said.
I've also seen on DealExtreme and other places some always-on, rolling-record capable video cameras for mounting wherever, and I've been tempted to pick one up and mount it in my car, police car style. Mailing a CD-R every month to the local precinct with video of their police officers flagrantly breaking traffic laws would be optional, but probably a lot of fun the first couple of times.
