Digital rights management in Microsoft products

[Pranav Lal <pranav.lal () gmail com>]

Hi all,

I have been asked to find a digital rights management solution for 
Microsoft products. Lets say that there is a Microsoft Word document. 
The requirement is that functions like cut, copy and paste must be 
disabled until the user is authorized. The authorization can be 
through a certificate or password. I have not been given any specific 
criteria. Where do I look for such information?

Has any one had any experience with any drm solution?
