Coping With Digital Rights Management

  1. 1. Coping With Digital Rights Management Stephen Downes National Research Council Canada
  2. 2. Key Issues in DRM <ul><li>The challenge posed by file sharing – Napster, Gnutella, more… </li></ul><ul><li>Distributing protected content in an online environment </li></ul><ul><li>Protecting protected content </li></ul><ul><li>Personal privacy, security and preferences </li></ul>
  3. 3. Principles <ul><li>An Open Marketplace – no barriers to entry as a content provider </li></ul><ul><li>Multiple distribution models – paid content, free content, co-op networks </li></ul><ul><li>Multiple descriptions of online content </li></ul><ul><li>Simplicity – easier to buy than to steal </li></ul><ul><li>Multiple agents, decentralized model </li></ul>
  4. 4. Design Objectives <ul><li>Rights Expression: how to ask for payment (and to specify use conditions) </li></ul><ul><li>Transaction: how to actually make the payment, and </li></ul><ul><li>Rights management: how to make delivery of the learning resource contingent on the payment </li></ul>
  5. 5. Digital Rights Expression <ul><li>Defining rights expression – XrML, ODRL, DREL, Creative Commons </li></ul><ul><li>Referring to rights expression in learning object metadata </li></ul><ul><li>The role of “vendor brokers” </li></ul><ul><li>Support for rights expression in eduSource </li></ul>
  6. 6. Transactions: Key Considerations <ul><li>Control over the presentation of options – the use of rights expression as a search criterion </li></ul><ul><li>Trust in the payment mechanism </li></ul><ul><li>Ease of making payment – single point of transaction, aggregated payments or licensing </li></ul>
  7. 7. Transactions: Mechanisms <ul><li>The role of the “purchaser broker” – a “one stop” for purchasers, but choice and control </li></ul><ul><li>Mechanism for transactions: </li></ul><ul><ul><li>determine whether a payment is required </li></ul></ul><ul><ul><li>decision as to whether to approve the payment </li></ul></ul><ul><ul><li>make the payment </li></ul></ul><ul><ul><li>obtain authentication to access the resource </li></ul></ul>
  8. 8. Rights Enforcement <ul><li>Delivery based: the eduSource DRM will provide a method for a secure “key exchange” </li></ul><ul><li>Content based: eduSource will allow and demonstrated the delivery of encrypted or locked content (but these are defined outside eduSource itself) </li></ul>
