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.

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 are you trying to do? Why don't you just use full disk encryption?

I already use FDE. However, unless I'm wrong, FDE does not protect disk clone from occurring. Therefore, if one has access to the password, then also they have access to all my files; including the ones I specifically want to protect. Am I wrong?

So, I'll make it simple for ya, you don't need to understand why; however, I seek for some method that prevents files from being copied through disk cloning. Them files being encrypted or whatsoever doesn't do a thing if the password is known. Unless you propose a method by which the password used to decrypt/unlock the disk on device X doesn't work when it's cloned to another disk. If, somehow, one has to rely on another password to decrypt the disk on device Y, then that might make it work out.

I don't think that's possible without an OS. For encryption you need a strong passphrase.

Alright. Thank you for your input!
