Benefit of Open Standards as
defined by OMA
 Interoperability between infrastructure, devices
and services
 Less market fragmentation
 Healthy competition between suppliers,
operators and developers resulting in better
consumer propositions
 Lower cost of introducing new services
 Fast global service deployment
 Enriched user experience and compelling new
mobile services across service providers

How to achieve this
Interoperability?
 OMA provides:
 An architecture that links different components
together for End to End solutions
 in the case of OMA DRM : Content Issuers, Right Issuers,
DRM Agents, etc.
 OMA Specs are reviewed to be complete, unambiguous
and error free
 Frequent TestFests:





The last held in Helsinki:
During 4 days, 111 teams, 183 engineers, 10 enablers
For OMA DRM v2: 12 client and 8 server-side teams
Next TestFests in 2005 in Milan, Seoul, Düsseldorf
In addition bilateral testing

The Open Mobile Alliance DRM
Group
 OMA DRM is developed by about 50 companies from
the entire mobile value chain:




Content Providers
Information Technology Companies
Mobile Operators
Wireless Vendors
 The only open DRM standard
 Consolidated from DRM standardization at 3GPP, WAPForum
etc.
 Over 250 handsets in the market with OMA DRM support
 Operators are integrating DRM into their infrastructures
 Liasons created with industry organizations such as
MPEG, RIAA, 3GPP, MMCA, (ODRL) etc.
 Direct feedback from music labels (i.e. Universal,
Sony, Warner)

From where we came:
OMA DRM 1.0 for Light Media Content
Forward-lock
 Need for a mass market solution:
DRM Message
Content
 Timely and inexpensive to deploy
 For mass market mobile devices
 Did not require costly infrastructure
 Targeted protection for light media content
 Three levels of functionality
Combined delivery
DRM Message

Separate delivery

 Forward Lock prevents content from leaving device
 Combined Delivery adds rights definition
 Separate Delivery provides content encryption and supports legitimate
viral distribution (SuperDistribution)
 Specifications rapidly developed to reduce time-to-market
 Delivered specifications for implementation in Nov, 2002
 OMA “Test Fest” in Seattle in Nov 2003 to test DRM v1 interoperability
 Now approved enabler release

How we progressed:
OMA DRM 2.0 for Premium Content
 DRM solution is evolving with the mobile industry
 High bandwidth cellular networks becoming widely available
 Mobile devices with removable media and larger color
screens support downloading and streaming rich media
 Content and service providers eager to release rich
audio/video content and applications
 Greater security and trust management required to
protect high value content
 Need to ensure target device can be
trusted to keep content and trade secrets safe
 Need greater security to prevent content
from leaking out during distribution

OMA DRM V2 – Beyond Mobile
Benefits for End Consumers
 Advanced content management
 Storage and backup: move content and rights to remote
or removable storage and later restore to device
 Multiple devices: Move content and rights objects easily
between several devices owned by a user (2nd phone)
 Sharing between multiple user within domain
 Domain concept for sharing between devices in the same
domain (e.g. family)
 Unconnected devices
 Copy to CE music player device
 Export to other copy protection schemes
 Transfer music to DRM-enabled set-top box or computing
device

 Integrity protection for content and rights objects
 Explicit trust mechanisms
 Mutual authentication between device and rights issuer
 Device Revocation
 Secure multicast and unicast streaming
 Protected streaming and progressive download
 Wide variety of business models
 Metered time and usage constraints
 Subscription rights for content bundles
 Gifting
 Support for Peer-to-Peer and Messaging
 Super Distribution: Viral marketing and reward mechanisms

OMA and ODRL
 OMA DRM 1.0
 ODRL with its mobile profile provides light-weight REL
 OMA DRM 1.0 with ODRL now implemented in over
250M devices
 the de-facto-standard for open standards-based DRM.
 OMA DRM 2.0
 Backward compatible with OMA DRM 1.0
 Preference to keep ODRL also for OMA DRM 2.0
 Future OMA DRM extensions
 No decision yet, but likely backward compatible with
OMA DRM 2.0
 Probably continue the use of ODRL
 Ensure ODRL and the future work on OMA DRM are well
aligned

Outlook
 OMA DRM continues to evolve
 Current issues:
 Moving from candidate to approved enabler release
 >100 Change Requests for quality improvement
 Interoperability
 Successful first OMA 2 Test Fest last month in Helsinki
 Next DRM Test Fest in September in Seoul
 CMLA: trust and certificate management
 MPEG-LA patent pool; totally distinct from OMA
 Roadmap:
 DRM extensions: Broadcast, Removable Media, …
 Market feedback and requirements for new Version
 Mapping of future requirements between OMA and external bodies
 Establishing liaisons with DVB, MMCA, SDA, ODRL, …
 Involvement of parties beyond the mobile domain

OMA DRM - Conclusions
 For P2P mechanisms to work in a multi-vendor
environment, open standards are needed
 OMA 1 DRM is the de-facto standard for mobile content
 OMA 2 DRM is providing more security, new business
models and convergence between mobile and PC
 SuperDistribution is a viral marketing concept that can
lead to exponential growth for mobile content
 Extensions are closing the gap to make OMA DRM
suitable for other area’s, such as Broadcast and CE
