(More) Specifics:

  • Undoing the protection should include filling in a password.
  • The password should be different from the one used with sudo or any other passwords that are used for acquiring elevated privileges.

All (possible) solutions and suggestions are welcome! Thanks in advance!

Edit: Perhaps additional specifications:

  • With 'displace‘, I mean anything involving that resembles the result of mv, cp (move, cut, copy) or whatsoever. The files should remain in their previously assigned locations/places and should not be able to ‘pop up’ anywhere.
  • I require for the files to be unreadable.
  • I don’t care if it’s modifiable or not.
  • I don’t require this for my whole system! Only for a specific set of files.

    I ask for some method that prevents the file to even be copied through a disk clone

    Oh that’s quite simple! Just don’t have the files on the first disk in the first place. Make them a remote mount from a server, for example via sshfs, webdav, etc. Heck, even ftp if it comes down to it. That way, even though you can clone the disks, you can not get to the files if you don’t also have the full authentication requirements for the remote server (such as a password).

    At a conceptual level, you can’t do anything via root to prevent someone who clones the disk from… well, cloning the disk. Having physical access to a disk is a much higher level of access than even root, so if what you are looking for is for your content to not be cloned, you need to fortify physical access to the device.
