Perspectives on DRM

“DRM technologies … keep honest people honest”-- Fritz Attaway, MPAA

“Trying to make digital files uncopyable is like trying to make water not wet”

-- Bruce Schneier, BT Counterpane(noted cryptography expert)

The DRM Conundrum

Content owners– …require technical protection as condition of licensing– …try to fight the piracy battle on all fronts (law, technology,

education)– …will not subsidize DRM

Technology vendors– …want to sell new technologies that implement new content models– …see the Digital Home as the next huge opportunity– …see DRM as a necessary evil to get content licenses

Consumers– …want to consume content in convenient ways– …may enjoy new business models (e.g. subscription services)– …generally dislike DRM

Personal Network

Head End to Gateway Device

Successor technology to Conditional Access Encrypt the link

– Cable, satellite, IPTV

Pass along rights information– From offers in subscriber management system– To gateway device, e.g. STB

Minimize cost of incremental hardware in gateway device– Encourage adoption by gateway device makers

Slide 8

Gateway Device to Personal Network

Allow reasonable use throughout personal networks– Play on any monitor– Store for playback later– Transfer to portable device

Content owners becoming comfortable with this

Consumer electronics makers see next big market

Consumers generally scratching their heads (so far)

DRM Schemes for Personal Networks:The Axes of Power

Goal: become the control center & gatekeeper Set-top box axis: NDS, Thomson, Humax, Pace Micro,…

– Secure Video Processor (SVP) Alliance

Media player axis: Sony, Philips, Samsung, Matsushita– Marlin

Mobile handset axis: Nokia, Motorola, Sony Ericsson,…– Open Mobile Alliance DRM 2.0

Microsoft (axis unto itself): – Windows Media DRM, Microsoft Media Transfer Protocol

Apple– Maybe, someday…

Interoperability

Among existing DRMs– Coral Consortium (standards group):

everybody but service providers

De facto standards– See “axes”

Escape to analog– Domain of copyright law and Fair Use

Hack– Anticircumvention law

Slide 11

Watermarking

Slide 12

Video Fingerprinting

Examining content in order to identify it– “Take its fingerprint”– Filter: block identified content from upload– Or do something else – serve a related ad, charge a fee, etc.

Reasonably proven technology for music– Less proven for video

Bone of contention in Viacom v. Google litigation– Attempt to extend Grokster and secondary liability law to include a

duty to filter

Focus of “UCG Principles” document– CBS, DailyMotion, Disney, News Corp, NBCU, Veoh, Viacom, Microsoft– Encompasses fingerprinting or watermarking
