Now is the time for vendors to consider implementing a duress password. Upon entering your duress password the user is presented with a fake profile, or perhaps everything could just be wiped. I'm not sure how well this would play out in the real world, but it's one of the best things protections I could imagine if you want to carry sensitive data across borders.
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 cas…
Applying it to phones seems a bit unrealistic, given that so few people will actually use those features.
