Someone without the password but with permission to modify the file will be capable of corrupting it (which would prevent you from accessing every protected file), but unless they somehow got access to the password they wouldn’t be able to view or modify the protected files.

Is it possible to force a corruption if a disk clone is attempted?

Scratch that, i missed a line. So simply files stored but not user readable.

But also not being able to be copied; even through a disk clone.

The thing with file permissions is that I or root are able to change that. I am looking for a method (if it exists) that somehow bypasses that.

Do you need it to be failing on every device or just on a device that you control?

Actually, I’m fine with a solution that only works on a device that I control. But, failing on every device is nice as well.

I’ll straight up pose the question I asked someone else:

It seems I wasn’t clear as most people misunderstood me.

But, to give a very precise example; say

  • I had a folder called ~/some/folder.
  • It was on an encrypted drive.
  • And I had done additional work to encrypt the folder again.
  • And say, I used chattr, chmod or chown or similar utilities that remove access as long as one doesn’t have elevated privileges.
  • And say, I had done whatever (additional thing) mentioned in your comment.

Then, what prevents whosoever, to copy that file through cloning the complete disk?

Even if they’re not able to get past the password, it will be found on the cloned disk. SO, basically, I ask for some method that prevents the file to even be copied through a disk clone. I don’t care that it has three passwords protecting it. What I want is for the disk clone (or whatever sophisticated copy/mv/cut or whatsoever utility exists) to somehow fail while trying to attempt the action on the protected files.

If you could be a bit more specific about your threat model people may have better ideas to help.

Threat model is me protecting myself from myself.

Incoming XY problem.

I want to prevent myself from reinstalling my system. The trick I came up with involved the use of files that couldn’t be disk cloned. However, if it’s far far easier to accomplish it through other means, then please feel free to enlighten me on this.
