Rights Management is Wrong For the Net, So Far Mark S. Manasse Compaq Systems Research Center Palo Alto
We’re All Dedicated Professionals Here § Innovative technical solutions to hard problems § Recognition of many broader issues § Despite my heresies, I agree with almost all of what almost all of you have said § Well-considered approaches to satisfy the demands of your clients § But ….
Your Client (well, Hollywood) is Wrong (for so many reasons) § History § Technology § Users of content § Collectors § Archivists § Future § I’m talking about mass-market static content
A Call to Arms § Let’s remind ourselves why our major clients are concerned--they should be § Let’s work on things which help in the long run § Let’s work on our customers to accept reality § Let’s offer solutions which preserve economic roles, but not failing business models § Let’s find stable paths from where we are, not from where we were
Unencumbered Copies of Content Are Going to Exist § You know all this, but everyone likes to pretend § Copy protection has never worked – Either it gets broken, or it kills the technology – Supporting backup and recovery is too expensive § Watermarking is damage – Files have added noise to encode watermark § Content is made noisier and less compressible – Capture and reencoding avoids restrictive players – Scrubbing is historically easy, despite denials § Rights management is one-sided – Preserves copyright-holders interest – Destroys first-sale expectations of users
Peer-to-peer Sharing Today Is § Economically sensible – Uses “free” resources § Floor space, disk space, and processor are free § Network is currently billed at flat-rate – Distributes contents (potentially) from nearby § Hard to kill when built as open software – Legal action doesn’t work – Exploiting bad protocols does § Spammable (for now) – It’s easy to create files with bad content (but same length as true file), so validating content is useful § A tool, not an enemy; Akamai for free
Preserving the Expectations of Users § Fair or conforming use is best decided by users and the courts, not software § Users are audience members; fans, not thieves § People like to build durable collections § Archiving and lending libraries are expectations § Rights expression and awareness are good § Rights enforcement is not – Prohibiting reasonable actions encourages circumvention – Today’s rights many not fit tomorrow’s notions
Towards Rights Encouragement § If rights are easily obtainable, there’s nothing wrong with nagging about apparent violations § But only if remedies are suggested § And only if one remedy is “I think this is OK, because…. ”
Licensing for collectors § Expression of rights is important, enforcement isn’t § Content will be freely distributed (like it or not) – Attached license describes rights – Attached URL tells you how to buy more § License includes signature and notarization – Public-key history, but not revocation § License includes licensee identifier (or nym) – For compliance checking – For pyramid-scheme sublicensing (superdistribution) § Digital notarization allows license secondary market
Rewarding the Distribution Chain § Revenue from licenses should be shared with the licensee from whom content was retrieved § Allows commercial content distribution, when economical (so Tower Records starts a really big Napster server) § Encourages licensing by the public
Finishing Touches § Licenses become the collectible item – Markets exist for used books, records, Pokemon cards, comic books, etc. – Serial numbers and limited editions, coupled with date of notarization to create scarcity § Blended schemes involving subscriptions and sponsorship are possible – Syndicator can offer bundled package of licenses – Like cell-phone contracts § Licenses may be permanent, but may also have limited duration or rights (e. g. , for lower price)
Sticks and Carrots § For users – Fans want to support artists – Players nag users to take positive steps to do the right thing – Legal pursuit of some to show that there are teeth – Tie extras to licensing § Advance notice of concerts, new works, chat rooms, etc. – Collectibility § For content providers – It’s easy to try § Add URIs to existing slots in MP 3 files and others § Add easy payment and compliance to players § Release content massively – It doesn’t make things worse – It converts threats into channels – It might work
