Not to say what you're doing isn't helpful, just that it is near impossible to fully protect any android device (or any tech really) but depending on situation there are many things to make unwarranted use very difficult
Best of luck with your project!
We're using galaxy tabs. And the only way to do anything with this tablet, with the mods I have running, is to hold the power button for ten seconds. That forces a reboot. You then have to try to press the right buttons as soon as the reboot starts to get into recovery. There is no way to power off the tablet without just letting the battery run down.
So one can get into recovery, but it isn't as easy as normal given the way the power button is being hacked with an Xposed module.
This is why I'd love to password protect the recovery. That's the only way someone could do any damage to the software I have installed. Even though it is harder to get into recovery than normal, it can still be accessed. And I'd rather keep the recovery around so I can do backups and restores without having to use a computer at all.
