How to apply DRM to files

[rasana]

Hi All,

How to apply DRM(DIGITAL RIGHTS MANAGEMENT) to files?

[dclamp]

what types of files?

[rasana]

video files

[dclamp]

ok well i am not exactly sure what you are wanting to do. Do you not want people to be able to download video files from your site?

[rasana]

yes..people should download video files from site and video files should be DRM protected..How would I apply DRM to video files?

[dclamp]

i actually dont think that it is possible for php to do it. You could do it manually and upload to your site... thats what i am thinking.

i am off to bed. good luck

Ok. but how can we apply DRM manually?

DRM is a generic name for the process of copy prevention. There are many DRM technologies and none of them are very effective. Most are only used by big record labels and even then people still manage to copy the content. I suggest that this exercise is somewhat futile.

Thanks penagate!!!!
Actually it's client's requirement. Client wants that files downloaded by users should be DRM protected. I don't know how to apply DRM to video files using PHP

Those are annoying, aren't they?

Well, nearly everything I can find on the web concerns removing DRM protection, not adding it. I believe Apple and Sony licence their DRM technology [edit: they don't], but I imagine a licence would be prohibitively expensive. Microsoft have some licencing system for Windows Media files, but I don't know how one obtains a licence or adds it to a file, and there doesn't seem to be much information (at least what I can find quickly on Google).

As for applying DRM, whatever solution you go with should include a command-line executable which you can call from PHP using exec or passthru or their related functions.
