  1. Was on ABC News TV yesterday: http://bit.ly/kozVL Not my usual subject but fun nonetheless.
  2. Last talk of conference: hard core macho-man talk about trusted computing platforms.
  3. Could be a very interesting way to implement the FTC's potential mandatory rights labeling scheme, as discussed at hearings back in Feb.
  4. Licenses are digitally signed and can be used as receipts from retailers.
  5. green = right to play; yellow = no license; red = illegal to play; blue = right to send to a friend.
  6. Tracking tool to show what rights you have. Simple color code:
  7. Next paper: Usage Rights Management. Files sent to users with license information. User maintains his own licenses.
  8. Goal is to build security features into STBs, adding huge hard drives, and letting them move content around instead of relying on servers.
  9. Next talk: a P2P architecture for distribution of broadband content, instead of trying to serve it all from server farms.
  10. I should really write a paper about this. But where to publish it?
  11. Centerpiece of talk was use of Lessig's 4 factors (architecture, norms, law, market) to assess success of DRM.
  12. My own talk was "The Trajectory of DRM: Past, Present, and Future." It went on too long, almost kept people from lunch.
  13. Seems similar to Cinea's Running Marks technique - could be good for video.
  14. Precalculate one copy with each bit in watermark set to 0 and 1, then just combine them as appropriate for transactional watermarking.
  15. Technique for dramatically speeding up watermark insertion through pre-calculation of insertion locations.
  16. Paper from Fraunhofer about using watermarks to protect digital images on web pages.
  17. Yet it seems to only work at the level of artists, not songs or albums. Needs identifier scheme!
  18. Very innovative search technology - sort of a cross between semantic document analysis and "folksonomy" user tagging.
  19. Paper from startup 4FriendsOnly (4FO), doing music search combining user tagging with analysis of text about the music found around the web.
  20. Therefore it's ultimately a matter of rights holder permission granting. Rights semantics are in the eye of the rightsholder.
