My BackgroundMy Background• Eduworks
– Help organizations design and implement e-Learning strategy and technology
– Help vendors understand e-learning market and design products
– Work in standards
• Personal– Recovering academic (mathematics, education
reform, academic administration)– Not a lawyer
• Know about DRM through work with standards, clients, and research projects

Digital Rights Management is the process of defining, tracking and enforcing permissions and conditions through electronic means and throughout the content lifecycle.
NOTE: Definitions of DRM often emphasize enforcement, but enforcement is only part of the picture.
![Page 5: The “Rights Stuff” Digital Rights Management Robby Robson President, Eduworks Corporation Chair, IEEE Learning Technology Standards Committee rrobson@eduworks.com.](https://reader035.fdocuments.in/reader035/viewer/2022062713/56649ce55503460f949b33e9/html5/thumbnails/5.jpg)
Permissions and ConditionsPermissions and Conditions• Rights define what you are permitted to do with digital content
• Conditions define when and under what circumstances you can do it
• Example: – Permission: You may use software– Condition: Provided you have paid for the license.
• Example: – Permission: A user may download a PDF file– Condition: Provided the user is an association member– Condition: And the user does not re-distribute the file
• Example:– Permission: You may use my joke in your presentation– Condition: You tell it well– Condition: You give me credit
![Page 6: The “Rights Stuff” Digital Rights Management Robby Robson President, Eduworks Corporation Chair, IEEE Learning Technology Standards Committee rrobson@eduworks.com.](https://reader035.fdocuments.in/reader035/viewer/2022062713/56649ce55503460f949b33e9/html5/thumbnails/6.jpg)
Rights EnforcementRights Enforcement
•Rights are legal, ethical and moral constructs.
•People, not software, grant rights.•Technology enforces rights by permitting and
denying actions (view, print, copy, edit, etc.) •Example
– An application won’t run unless a license key is provided.
•Example– A PDF file produced so it can be viewed but not printed
•Example– Content will not be delivered unless a valid identifiers
are provided and verified for all cited references.

Rights ExpressionRights Expression
• Technology must know what permissions to enforce and what conditions to check
• Rights Expression Languages provide a standardized way for permissions and conditions to be expressed in a machine (and human) readable form.
• Rights Expression Languages serve other purposes as well
![Page 8: The “Rights Stuff” Digital Rights Management Robby Robson President, Eduworks Corporation Chair, IEEE Learning Technology Standards Committee rrobson@eduworks.com.](https://reader035.fdocuments.in/reader035/viewer/2022062713/56649ce55503460f949b33e9/html5/thumbnails/8.jpg)
AssumptionAssumption
There are reasons and requirements to express and
enforce conditions and permissions

Challenge #1: EnforcementChallenge #1: Enforcement• Authentication and Authorization
– Of people (and agents and services)– Of object (e.g., through digital
watermarks)
• Prevention and Protection– Through software and hardware keys
(e.g., e-books, Palladium, etc.)
• Enforcement through the justice system
• Enforcement is NOT the topic of this presentation
![Page 11: The “Rights Stuff” Digital Rights Management Robby Robson President, Eduworks Corporation Chair, IEEE Learning Technology Standards Committee rrobson@eduworks.com.](https://reader035.fdocuments.in/reader035/viewer/2022062713/56649ce55503460f949b33e9/html5/thumbnails/11.jpg)

Challenge # 4: The Legal LandscapeChallenge # 4: The Legal Landscape
• Copyright– Changes over time– Differs from country to country– Was meant for something else
• Patents– Apply to intellectual property– Apply to DRM technology

Example: The TEACH ActExample: The TEACH Act
• Technology, Education and Copyright Harmonization Act
• The TEACH Act grants and exemption – ONLY to accredited non-profit educational
institutions – ONLY for the online equivalent of displays and
performances that are shown as part of a class under instructor supervision
• THE TEACH Act requires– Institutions to have and follow copyright policies– Institutions to use technological protection against
unauthorized, unintended and illegal use

Copyright DiversityCopyright Diversity
• In the former British Colonies:– Assignable– Fair use and “work made for hire”
• On the European Continent– Right of the author
• Different in Asia• The fundamental act of
transmitting and processing data is copying

Challenge #10: DRM As Part of an Overall Content Strategy
• Organizations Develop Content Strategies to – Gain efficiency through uniform policies– Improve workflows by providing a common
understanding of the structure of content– Exchange of content with other organizations– Inform acquisition of content– Inform internal and external content creation– Guide management, workflow and technology
decisions

Reference Models and Content Models
Reference Models and Content Models
A reference model• Gathers and
documents specifications and best practices
• Is concrete enough to show the way
• Is general enough to open the way
A content model• Defines an
organization’s content building blocks
• Defines objects and how they fit together
• Helps define the content development workflow

Digital Rights StandardsDigital Rights Standards
• DRM standards are being developed on an international level
• Foremost among these are activities taking place within the Moving Picture Experts Group (MPEG) under ISO
– Working on comprehensive set of DRM interoperability standards
– Furthest progressed towards standardization– Most likely to be adopted by product vendors
and content producers
![Page 42: The “Rights Stuff” Digital Rights Management Robby Robson President, Eduworks Corporation Chair, IEEE Learning Technology Standards Committee rrobson@eduworks.com.](https://reader035.fdocuments.in/reader035/viewer/2022062713/56649ce55503460f949b33e9/html5/thumbnails/42.jpg)
The MPEG Rights Expression LanguageThe MPEG Rights Expression Language
•MPEG REL creates digital “licenses” that–Record and express permissions and conditions–Express conditions for issuing new licenses
•Applications can read, write and enforce permissions and conditions in a standard way
•Only “positive” rights are expressed
• As content moves from system to system, licenses generate a “virtual paper trail” documenting organizational diligence and adherence to laws and agreements
![Page 43: The “Rights Stuff” Digital Rights Management Robby Robson President, Eduworks Corporation Chair, IEEE Learning Technology Standards Committee rrobson@eduworks.com.](https://reader035.fdocuments.in/reader035/viewer/2022062713/56649ce55503460f949b33e9/html5/thumbnails/43.jpg)
