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
- 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
- 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
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
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
- 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.
