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.

I guess you can use ACLs depending on your filesystem, or SELinux user contexts.

Seems interesting. Got any sources to read up on? Thanks in advance!

You can read about SELinux here or ACLs here. SELinux can be pretty complex if you've never used it, so make sure you understand it well. I believe it should be able to do what you want to achieve.
