This presentation is made from an IEEE transection: IEEE Computer April 2009

1. How viable is Digital Rights Management

3. The term is used to describe any technology which makes the unauthorized use of digital content.

4. Sony, Apple Inc., Microsoft and the BBC use DRM technology.2 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

6. This gives rise the interoperability issue among DRM schema.

7. So to built a trusted infrastructure to protect the content is being difficult.

8. The computer community revisit the current approaches.3 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

9. Early Technology Encrypted with K1 Content Purchaser 1 Having k1 Content Rights Encrypted with K2 Content Purchaser 2 Having k2 Content Content provider Rights Encrypted with K3 Content Content Purchaser 3 Having k3 Rights 4 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

10. Second Generation DRM Encrypted with K1 Encrypted with K Content Purchaser 1 Having k1 Rights Content K Encrypted with K Content Encrypted with K2 Content Purchaser 2 Having k2 Rights Content provider K Encrypted with K3 Rights Content Purchaser 3 Having k3 K 5 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

11. Current Architecture Financial Clearinghouse Content Provider End user web server Rights Clearinghouse 6 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

12. DRM Security Model Attacks Attacks Rendering Application Content Provider Attacks 7 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

15. Building-block-based interoperability

16. Transformation driven interoperability8 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

17. DRM Interoperability User device Interoperability services/ interfaces DRM Interoperability framework DRm 1 DRm 2 DRm n DRm schemas 9 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

19. PKI(Public Key Infrastructure) is an example of trust model.

20. For Example:

21. OMA(Open Mobile Alliances) use PKI

22. MPEG-21 DRM schema does not specify a particular authentication framework.

23. These differences makes complexity. 10 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

25. Preserving the protection level

26. Building a trusted environment.11 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

28. A strong platform should make at the business level to protect unauthorized data passing

29. The new technology should enough friendly for the user.12 Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh
