On entering Canada, I've been asked to open my laptop, turn it on, enter an administrator level password, and then search for *.jpg. Everything shows up -- cached browser images as well. The agent asked a lot of questions, but I was allowed to pass eventually. This all took place out in the open, where they would normally collect a form from you.

I immediately started using TrueCrypt with the plausible deniability option, which allows you to enter an alternate password to open a completely different part of the encrypted area seeded with some random files that look realistic enough to pass scrutiny.

It was always fun to unmount the volume and remount it with the plausible deniability volume. Or, just shutting down before crossing the border and knowing that, if needed, I'd enter the alternate password.

Recently I started using a Mac and Apple's own full disk encryption, but reading this just highlights the risk. Maybe I should start using TrueCrypt again.

Ugh...it's frustrating.
