Comment This is not DRM (Score 1) 369
You have to separate DRM, which is a type of protection designed for short-term media protection, from content-based information security. The former fails by security through obscurity, the latter is a very interesting, but very difficult research area, and if you (or anyone) were to come up with any cross-vendor implementation of a working solution, you would advance the security of information exchange between partners manyfold.
