There are many techniques to make a phone "know" whether you are the person using it, and many things that can be done in that case. I see two possible orthogonal courses of action:
* Add stuff to know whether the user is the owner: - It could ask you a password from time to time, or when the phone "brought to life from suspension", and do something if you fail to provide the right password too many times. - Since locking a stolen sim is quite easy, changing the sim could be a symptom of a stolen phone. - In a more ideal world, it could "listen" to you and play the voice identification card. - Also in a more ideal world, it could probably measure the length of your step when you walk. * Act if the user is not the owner. - Gather data to ID the user and locate the phone (GPS coordinates, current sim card data, whatever). - Send it to you (by SMS, email, whatever) silently, or publicly post it on some website: "Hi, my name is FR, and I've lost my friend Jimmy. I'm currently being held up in XXX. Help me Openmoko Community, you're my only hope". - Record it somewhere in the phone (so that it cannot be easily removed). - Disturb you as much as possible: lock the phone completely or show a big sign with the word "stolen!", play a sound aloud, add fake SMSs from (possibly) fake mistresses; download illegal porn from the internet (and play it fullscreen); play strange sounds in the middle of conversations. Invert the screen every now and then; call erotic services periodically after you put the phone in silence mode, with the speaker on; call "bomb!" really loud when set if "airplane" mode; turn the vibrator on (permanently, or even better, randomly); wake you up in the middle of the night and when the phone is moved, say "Sorry, did I wake you up? I wouldn't if you gave me back my f***cking phone!" - Send stuff to your contacts: like "Sorry, life is just too awful. I can't go on. Last night I even stole a phone!". - Register a twitter account, and publish everything the user does, where he goes, etc. Just to name a few... :) It's a pity it doesn't have a camera, that would have been soooo awesome.
