The IEEE P1817 working group has come into effect last month and proposes a file protection system that aims to allow users to share their digital files but keep them protected from outright copying at the same time. Known as Digital Personal Property (DPP), it includes two pieces of a digital file and would be a less restrictive alternative to DRM file protection. There would be a title folder and a playkey. The title folder would contain the encrypted file, while a playkey would grant access.
