I agree with you, in that it would definitely be an awesome thing to have, even though a lot of people see little point in it because it’s not “real security”.
But it could very well be the difference between an agent waving you though at a checkpoint because your machine “seemed clean enough” after checking out a few folders indiscriminately, or being escorted away in handcuffs because someone thought anyone who uses a terminal was “one of those hacker types”.
What it would not be good for
- Any forensic analysis of your machine. You’d be totally screwed…
- Safeguarding against any remote access
- Providing any actual security (Sorry, but it’s true…)
What it would be good for
- Fooling security guards, border agents, security checkpoints, or anyone else who isn’t exactly “tech-savvy”
- Tricking someone into typing in a password if you’re under duress, and that password would actually wipe your device, notify someone that you’re in danger, or anything else you like.
The world is currently watching people being stopped in the streets by police officers in multiple places around the world, and are having their phone searched manually (no forensic analysis, at least not with a wide net).
Just a quick “See? There’s nothing there. I told you that!” could be all it takes to save someone’s life
