Color Scrambling for Secure Digital Content Distribution

Editor's Notes

11. A color management module (CMM) uses the profiles to go back and forth between devices (via the PCS) using a number of mechanisms of the ICC profiles
18. We turn ICC around: we use different, non-standard PCS spaces and “misuse” the CMM to en-/de-code images to/from the scrambled PCS
25. 1. photographer contacts print service provider 2. print service provider retrieves scrambling ICC profile from printer of photographers choice (unscrambling internal to printer) 3. PSP sends ICC profile to photgrapher 4. photographer converts a copy to scrambling ICC profile and sends it to PSP scrambled image is useless to any 5. PSP sends scrambled image to correct printer to be printed (correct unscramling profile is applied internally)
