I am having a hard time imagining how the system can be made to understand whether a user is under pressure to reveal data. Perhaps a spoken phrase from the us

  An easy mechanism is have two passwords. The real password that displays unredacted data, and a contingency password that only reveals benign information.

    ... or a contingency password that causes the phone to immediately be wiped clean and then unlocks? Still doesn't address the notion of a system that "knows" the user is under duress without some sort of overt signal or action by the user.

      BlackBerry had a duress password feature to secure erase the device in the event of said password being used, and it would brick the device in the event of being aborted (battery pull). Wouldn't that be considered destruction of evidence though?

        not if the police used the password themselves, especially if there is no specifier for what password is requested. alternatively live dangerously and default wakeup mode is to trigger the self destruct, unless the trigger is deactivated [by a password of course.] if the cops dont know how to use your phone and they brick your phone they have caused damage. im not sure how well it would work if they plugged your "phone" usb port into thier equipment, only to realize your "phone" is actually a super capacitor device, with a charge level display. It could be sabotage, but we are developers and engineers after all so all sorts of prototypes could end up in the hands of someone ignorant of the device function. Im sure a warning "you dont want to plug that in there!" would fall on deaf ears but is a point in your own defence.
