Conversation Outline Digital Rights Management (What is it?) Ten Challenges of DRM 1.Enforcement 2.Heterogeneous Content 3.Heterogeneous Application Domains 4.The Legal Landscape 5.Complex Technology 6.Complex Content 7.Federated Repositories 8.Services and Distribution 9.Standardization 10.DRM as Part of an Overall Content Strategy Rights Expression Languages Discussion

Digital Rights Management DIGITAL CONTENT PRODUCED STORED DISTRIBUTED RETRIEVED & COMBINED USED 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.
5
Permissions 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
6
Rights 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.
7
Rights 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
8
Assumption There are reasons and requirements to express and enforce conditions and permissions

Challenges
10
Challenge #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
11
Challenge #2: Heterogeneous Content Content Runs on Many Platforms –Windows, Unix, Mac, Internet, Intranet Content Comes in Many Formats –Text, Video, Audio, e-Books, PDF, Flash, Windows Media, MP3, etc.
12
Requirements Requirement: means of expressing and managing rights that –Is persistent –Works with heterogeneous content –Is platform independent
13
Challenge #3: Heterogeneous Application Domains Heterogeneous Stakeholders –Authors, Publishers, Distributors, Consumers Heterogeneous Cultures & Communities –Education and Training –Private, Public, not for profit –Linguistic and Political –Specialized Communities of Practice
14
Requirements Requirement: means of expressing and managing rights that –Is persistent –Works with heterogeneous content –Is platform independent –Is locally adaptive yet globally authoritative
15
Challenge # 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
16

17
Example: 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
18
Copyright 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
19
Patents Enforcement Technology is patented Cryptographic techniques are patented DRM is subject to patents –ContentGuard Association of usage rights to content. A grammar to define rights or conditions. Persistent protection. Distribution of composite digital content. Fee accounting and reporting associated with the distribution or use of content. –InterTrust (now Sony) Standards may be subject to “Reasonable and Non-Discriminatory (RAND)” patents

LEARNING CONTENT RIGHTS MANAGEMENT CYCLE DIGITAL CONTENT PRODUCED RIGHTS ATTACHED VIA REL DIGITAL CONTENT DELIVERED DIGITAL RIGHTS ENFORCED
41
Digital 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
42
The 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
