I really wish mobile device vendors would add support for multiple unlock modes. E.g.:
* "Me mode" that unlocks everything.
* "Kid mode" that only allows one's kid access to pre-approved apps and features.
* A "lend to a stranger to make a call" mode that is a lot like the kid mode, but it also causes the phone to start broadcasting its GPS location frequently (and refuse to turn off [though it might fake it]) in case the stranger steals it.
* An "under duress" alternate PIN that unlocks an alternate profile full of nothing but benign activity, with no indication of (or access to) the encrypted real profile. Once in this mode, the phone cannot unlock normally without a non-phone 2-factor authentication (e.g., email).
All but the last could use the normal PIN, perhaps with different "submit" buttons. I would also love to see the same thing on ATMs, where an alternate "I'm being robbed" PIN will show a fake, low balance in the account and limit withdrawal to that value.
That idea is so good. The ATM could also sound a silent alarm, just like some home alarms do. The phone could maybe even start recording all interactions and automatically submit to something like ACLU.
The silent alarm idea is excellent. Perhaps this could also trigger the machine to scan and store the serial numbers of the dispensed bills, so the bills themselves could become evidence of the crime.
That ATM idea sounds pretty cool honestly.
Applying it to phones seems a bit unrealistic, given that so few people will actually use those features.
