Company to sell the equipment and open environment for the user to programming, in order to prevent competitors copy we write good libraries, the libraries have to be protected,

requirement is the ability to read, but not copy , because users need programming need to call to or how to carry on the protection of these libraries? Even if be copied also doesn't work?

Chmod, I tried to set up a read-only access these files, but they were not affect cp command copies,

I also find some encryption technology, such as luks, but need to disk encryption, installation system, again is to want to reinstall system, and I don't know what it can to prevent copying,

For Linux permissions, I know not deep, only know RWX, but not make sense to prevent copying,

Excuse me each great god, and to protect the ubuntu system have what skills?

CodePudding user response:

I have seen many posts, teaching how to copy and paste, such as in the command line, enter sudo nautilus, can deal with difficult without permission, when copying and pasting

Ubuntu some files need root access to copy and paste, and how to operation it?

So I'm curious, how to set these permissions, and then I will be a regular user remove sudoers list, they will not be able to copy and paste, but how to set?

CodePudding user response:

If you think what paid software can solve the demand, also can recommend,

CodePudding user response:

Can read it can replicate, cat XXX & gt; XXX is not finished, eventually requires encryption

CodePudding user response:

Encryption or put the stuff on your own server lets users connected to the Internet to play,

Don't want to set the permissions, if not the cat, a u disk boot disk boot, mount, read, who have to live, don't you also can give the user's disk encryption,

CodePudding user response:

But encryption not shackled to go, you also need to let the other side can't use, do absolutely not as good as in the repository to be hardware binding, this equipment can only wait for the equipment had been stolen,
