Having worked in counterintelligence, we would regularly insist that international travel be conducted with as little sensitive data as possible. It was generally assumed that when passing through customs, they would and could gain access to any data that was in your possession. Organizations sometimes issue travel laptops that are basically wiped prior to departure. We may of become too comfortable with the idea that a phone’s encryption is going to protect us against state actors. One thing that would be cool is if you could program a duress PIN that would factory reset your phone discreetely.
