Absolute protection against downloading files from the site?

Question

Copy protection

HLS video and audio stream. In view of the public copyright content, I would like to know how to prohibit its downloading.
Temporary links for content, temporary authorization tokens for accessing content, CDN.
What else?

Answer 1

My opinion (I do not pretend to be faithful) but everything that got into the browser can be downloaded ... it will end up in TEMP or in Networks

Answer 2

If it's only about downloading, then you need to make a private download link. Preferably access only. The link is one-time AND virtual, that is, it should not have direct access to files
