I don't see how this can work. Like all DRM schemes this breaks down the first time a user decrypts the message. At that point you simply make a copy of the decrypted data. Am I missing something?
- mahmud 17y agoNope, that's about it. "Content providers" should see what DRM + Open Source did to the shareware industry.
- ghshephard 17y agoIt's actually a little more interesting than trying to DRM documents - it's a mechanism in which documents _decompose_ over time in a completely delegated manner. Quite clever, actually. It's a way for people to send documents back and forth to each other without worrying about discovery later on, post documents/embarrassing pictures onto facebook, etc.. - At some time in the future, when the keys have fallen out of use and if (BIG if) nobody else has bothered to make a copy of the documents, then they will have just disintegrated. Poof.
- kragen 17y agoI don't know much about this new scheme, but it sounds like Disappearing Inc. The objective of Disappearing Inc. wasn't to prevent employees from leaking internal documents on purpose; it was to prevent them from accidentally retaining documents they shouldn't have. This may be the same thing, but with a clever new implementation. That is, the intended recipient of the message isn't the adversary. So this might be a tractable problem, unlike DRM.
