Safe Data-Wipe

The day will come: your good-old Android shall get replaced by a newer model. If you no longer need the "old one", you probably want to give it away. But you certainly don't want the new owner accessing your sensible data which might have been stored on it. So what to do?

There's of course the Factory-Reset. But does it really sanitize your data in a way they cannot be (easily) restored? Unfortunately, that's not the case: though they are deleted, they are not wiped – so with the right tools, they could be restored. Admitted, that takes some little knowledge and work – but it's possible. A good counter-measure is to really "nuke" or "wipe" the storage – i.e. overwrite it with "random patterns". Corresponding guidelines are described by the National Institute of Standards and Technology (NIST) in a PDF Dokument.

Automated Deletion

2021-01-08

Not quite a safe wipe as described above – but still a welcome helper: automatically do a factory-reset / delete all files, if the number of unsuccessful unlock-trials exceeds a certain threshold. That at least makes it more difficult for the attacker to access your data. Unfortunately, none of the few apps in this group is available anymore.
