  1. Digital Inheritance of Personal and Commercial Content Using DRM H. Li, NXP Research M. Petkovic, Philips Research CCNC’07 DRM workshop, Jan 11 2007

  2. Content • Introduction • Private content protection model using DRM • Inheritance protocols • Digital last will • Conclusions

  3. More will be protected for privacy and for copyright Hackers & Users & Observers People own and manage exploding amount of digital content in the whole life • Personal content and commercial content • Personal digital history: photos and video, health info, financial info, behaviours, … • Music, movies…

  4. How to regulate inheritance of digital property? • Traditional ways insufficient • Free copy or paper last will: usage rights issues • Not easy for managing a huge collection • Traditional ways may fail for confidential content protected by cryptography • His keys, private knowledge and biometric authentication may be lost forever, if a person is dead

  5. Secure digital inheritance solutions are required • Requirements: • Trusted posthumous transaction of the inheritance • Secure process for encrypted personal confidential content • Secure process for transferring usage rights of commercial content • Options for testator to assign conditions and rights to a beneficiary for a particular digital bequest • Non-repudiation • Ease of use

  6. Content • Introduction • Private content protection model using DRM • Inheritance protocols • Digital last will • Conclusions

  7. Private content protection model using DRM • Personal keys and license process capability are in compliant devices • Ownership secured in Owner Licenses • Owner License (OL): full rights, incl. to grant rights to others • User License (UL): usage rights given by the owner

  8. Owner 1 grants ‘takeOwnership’ UL Owner 2 takes ownership Owner 2 asks to clean-up the old ownership Owner 1 cleans the old ownership Ownership and ownership transfer ULx : TakeOwnership UL ULClean : Clean-up UL Secured by compliant personal devices (keys)

  9. Content • Introduction • Private content protection model using DRM • Inheritance protocols • Digital last will • Conclusions

  10. Digital Inheritance Protocols • Principles for inheritance of digital content using DRM • by adding inheritance information (including conditions) to content licenses • by binding activation of inheritance to a death certificate • Two examples of protocols for personal content • One example for commercial content

  11. Inheritance protocols of personal content (1) • Put inheritance information in an ownership license and coupling inheritance activation with the death certificate of the testator

  12. Inheritance protocols of personal content (2) • Put inheritance information in a usage license and coupling inheritance activation with the death certificate of the testator

  13. Inheritance of commercial content • Append an additional license with inheritance information and conditions

  14. Content • Introduction • Private content protection model using DRM • Inheritance protocols • Digital last will • Conclusions

  15. Using a digital last will • Using containers to secure the rights-transfer licenses • Selected executor / TTP opens the containers with the death certificate • Beneficiaries complete the inheritance using the right-transfer licenses

  16. Conclusions • Secure inheritance solutions required for protected digital content • Several protocols presented for transferring the ownership and usage rights posthumously • A digital last will solution presented • More work needed to introduce ownership and inheritance protocols in a real DRM standard / system
