Biometric fingerprint scanning technology appears to be evolving in quite interesting ways. Take this Ibidentifi system which does all the usual scanning stuff to protect your computa, but also includes an ‘alarm finger for duress’ feature. If you’re being forced to scan your finger to gain access, you just use a specially pre-chosen finger and lots of very silent alarms will be set off. I think it’s called duress finger mode. Interesting.
Gizmodo commenters have suggested some additional product features when the duress feature is activated, including providing the device location to the police, or exploding when the duress feature is triggered.
