I've been doing some research into some DRM solutions, specifically "self-protecting containers". One example of this is DigiBox. Normally, the protected data is encrypted in some kind of container. However, once the data is in use, it is decrypted in memory. What is stopping me from copying that data from memory and into another file on the harddisk?
For example, if I had some sort of Word document that is protected. Can't I click save-as? Or does some DRM solutions work with Word to stop this?
