How secure is a AES-128 encrypted archive from illegal copying and distributing?
If I have a database that is stored in an AES-128 encrypted archive, is this the most secure way of protection against illegal distribution (as torrents etc.)? Will it work as well for PDF:s also?
Somehow, this encrypted archive has to be tied to one single computer only (only possible to open on that particular computer). Is that possible today to guarantee success doing so, without any backdoors to tie it up and copy the PDF to other computers?
Will it have high copyprotection on any operative system, so that it's not easier on a Linux for example to modify the file and remove the copyprotection?
