2. Reuters Customer a straw-man sketch Example Customers: –Banks –Newspapers –Corporate Treasuries –Farmers’ Cooperatives –Broadcasters A business A professional consumer of data A manager of networked systems A user of automated processes A discerning owner of infrastructure Example Processes: –Printing and Publishing –Financial Trading –Audio/Video Editing

3. Reuters Products Information –multimedia news (including: text, still pictures, audio/video) –financial data –transactional data –editorial content –research reports Electronic Delivery Modes –discrete content files –continuous streams of discrete updates in real-time –historical data searches –transaction processing –proprietary networks and Internet delivery

4. Some Reasons why Reuters needs to “Permission” its Data The data is inherently valuable Service offerings contain lots of “slice and dice” Broadcast mode delivery is required in many cases for scalability; permissioning restricts access to just those parts paid for Distribution channels are flexible and varied (e.g., proprietary networks, satellite broadcast, public Internet) Third party content is fundamental and comes with complex and exacting rules for distribution (regulatory) Data flows are multi-directional and permissions also cover contribution rights

5. Problems with Today’s DRM Heavy bias towards “Eyes and Ears” Total Lack of Interoperability –Rights Mark-up –Operational / functional Concentration on prevention of copyright theft –nothing done about detection or action after the event No real support for B2B / business customers “Fair Use” / other complex models not supported

6. Eyes and Ears… Title: BRU04:BELGIUM-OWL:ANTWERP,BELGIUM,18FEB97 Author: nk/Photo by Nathalie Koulischer REUTERS Description: A nine-day-old Burrowing Owl chick is fed water through a syringe by a zoo keeper February 18 at Antwerp zoo. It is the first time that a Burrowing Owl chick has been hatched at the zoo. The chick, a native of North America, weighed 8.3 grammes when it came out of the egg and now weighs 24.6g.

16. What part, if any, might PKI play? Authentication –Users –Credentials –Applications –Infrastructure components Transaction protocols –Non-repudiation/Audit trails between clearing infrastructures Session-key management protocols PKI-style networks of trust (TTPs?)

17. Today’s DRM  Prevention Only Prevention Detection Action

18. Detection (Traitor Tracing) Adds Watermark (“fingerprint”) Application Consumer T

20. Revisit the Reuters Customer The Server Special Applications DB Well-defined Cost Centres Tight control over infrastructure (RDBMS, PKI, Desktop apps, DRM solutions,… ) Centralised staff admin

21. A Future for DRM? Reuters needs Permissioning –DRM is one possible solution among many –In its current form DRM is inadequate Open Standards / Interoperability required –In “rules” (XML) and for operational interfaces Additional technologies –PKI, Smartcards (trust on the card), Digital Watermarking, Traitor Tracing techniques (detection vs. prevention)
