How to prevent files from being displaced? This protection should (somehow) persist through disk cloning. (discuss.online)

(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.

What do you mean by a file being displaced? Like do you want it to be unreadable, or unmodified, or just not deleted?

It's not really possible to have a level of protection that would require more than sudo because with root access you bypass anything else.

You could put the files on an encrypted volume that uses a special password when it is mounted. Or you could use the chattr command to set special ext4 attributes that would make it unmodifiable (but could be removed with sudo). Or just record the file's hash, and that way you know it hasn't been modified later.

I don't necessariy care for any of those. They are 'bonuses' if you will. Though...:

  • Unreadable will be required for preventing recreating the file elsewhere.
  • Unmodifiable is not necessarily required. Maybe I would like to 'append' something to an existing file. But I'm fine either way. It should not be possible to delete some of the original data though.
  • Not deleted is a must as well.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
