Freedom to Tinker Blog: DRM Wars: The Next Generation
August 9, 2006
Prof. Ed FeltenPrinceton University, Dept. of Computer Science & School of Public Affairs
“Public policy about DRM offers a spectrum of choices. On one end of the spectrum are policies that bolster DRM, by requiring or subsidizing it, or by giving legal advantages to companies that use it. On the other end of the spectrum are policies that hinder DRM, by banning or regulating it. In the middle is the hands-off policy, where the law doesn’t mention DRM, companies are free to develop DRM if they want, and other companies and individuals are free to work around the DRM for lawful purposes. In the U.S. and most other developed countries, the move has been toward DRM-bolstering laws, such as the U.S. DMCA.”

Freedom to Tinker Blog: DRM Wars: Property Rights Management
August 14, 2006
Prof. Ed Felten
Princeton University, Dept. of Computer Science & School of Public Affairs “The new argument for DRM-bolstering laws is that DRM enables price discrimination and platform lock-in, which are almost always good for vendors, and sometimes good for society as a whole. The new arguments have no real connection to copyright enforcement so (I predict) the DRM policy debate will come unmoored from copyright.”

Freedom to Tinker Blog: PRM Wars
August 16, 2006
Prof. Ed Felten
Princeton University, Dept. of Computer Science & School of Public Affairs
  “[T]echnology is starting to enable the use of DRM-like technologies, which I dubbed Property Rights Management or PRM, on everyday goods. Today I want to speculate on how the policy argument over PRM might unfold, and how it might differ from today’s debate over copyright-oriented DRM.”

The Place of the User in Copyright Law
November 2005
Prof. Julie Cohen, Georgetown University Law Center“
Copyright doctrine is characterized by the absence of the user. . . . The essay traces the effects of the user's absence, and argues that a theory of the user is needed to restore doctrinal and theoretical balance. Specifically, it is commonly understood that users play two important roles within the copyright system: users receive copyrighted works, and some users become authors. Both roles further the copyright system's larger project to promote the progress of knowledge. But copyright law and policy have shown little interest in understanding the processes by which these roles are performed, nor in inquiring what users need to perform their roles in a way that optimizes the performance of the copyright system as a whole.”

New Digital Media Driving Market for DRM Tools
July 7, 2006
Mike Feazel, Asia-Pacific Broadcasting News, Staff Writer
“The race to provide DRM technology is far from over, with experts predicting incessant demand driven by easier digital retransmission. What features do content owners seek? . . . Clearly, the DRM market, while rapidly growing and seeing new opportunities in things like video-enabled mobile phones, remains largely in flux. Some fear that Microsoft could come to dominate the market, but the movement towards open standards for DRM and the number of fast-moving entrepreneurial firms like Verimatrix make it clear that the race is far from over.”

“Which is why we’re so excited about these personalized Jessica Simpson tracks. Not only is it pretty cool to have a version of the song which speaks to me (I was shocked to see they had “Ian”, did they do that for me?), but it’s in MP3 format, which I have no problem paying a little more for (though $1.99 is a premium price because of the PERSONALIZATION, not the DRM, the right price for MP3s is somewhere between $0.99 and there, IMHO).”

MESEC (Mobile Enabled Secure Exchange of Content)
Rene van Buuren, Project Manager
“Content providers are still hesitant to distribute their valuable content on the Internet. In many cases very strict usage rights are coupled to the content which is far from the 'fair-use' experience of consumers. . . . The MESEC ambition is to develop a secure content exchange mechanism that balances the advantages for both content owners and consumers.”

Critiques and Commentary of Initiatives

Watermarks: A better DRM than DRM itself?
November 20, 2005
David Berlind, ZDNet, Executive Editor
“[M]aybe, just maybe, there’s a glimmer of hope in yesterday’s announcement by TiVo. If TiVo’s ‘watermark’ approach to the same problem that DRM was meant to solve takes any root, I’m wondering whether most if not all of the problems created by DRM could be eliminated overnight. . . . In other words, content that you download and encode will be uniquely watermarked so it can be traced back to you. So, if you want to load something you recorded up to the Net for illegal distribution, go right ahead.  But don’t be surprised if the authorities come knocking on your door a few days later.”

Audible Magic — No Silver Bullet for P2P Infringement
July 12, 2004
Chris Palmer, Electronic Frontier Foundation, Staff Technologist
“Information from public sources suggests that Audible Magic's filtering technology is trivial to defeat. For universities, this means an investment today may well be worthless tomorrow. Policymakers, meanwhile, would do well to examine all filtering technologies closely before putting faith in the promises of vendors. A close look at Audible Magic's technology suggests that its filtering is no silver bullet.”

Navio Working on DRM Alternative to FairPlay
May 23, 2006
Victor Mihailescu, Softpedia News, Apple News Editor
“The company hopes to offer a DRM that stores the right information associated with a piece of music, a game or a movie in the file itself. But Navio plans to take things one step further and start offering a solution for iPod ready videos that anyone could sell. This will allow anyone to tap into the iPod, not just Apple.”

Consumer Protection Issues Posed by Sony BMG Copy-Protected CDs


Background

Wikipedia entry,
“2005 Sony BMG CD Copy Protection Scandal”
http://en.wikipedia.org/wiki/2005_Sony_BMG_CD_copy_protection_scandal
This article describes Sony’s installation of copy protection software onto its CDs that interfered with user’s computers and allowed computer viruses to easily infect user’s systems.  It also includes general information about the legal actions that have been taken in response to the problem.•

John Borland,
“Sony recalls risky ‘rootkit’ CDs,”
CNet News, November 15, 2005
http://news.com.com/2100-7349_3-5954154.html
This article details Sony’s reaction to the rootkit incident, including its recall of 4.7 million CDs it had shipped with the ill-fated copy protection program.

Bruce Schneier, Security Technologist,
“Real Story of the Rogue Rootkit,” Wired News,
November 17, 2005
http://www.wired.com/news/privacy/0,1848,69601,00.html
Schneier argues in this piece that the collusion of computer security companies and media content providers harms consumers because security programs do not adequately protect against problems like those caused by the Sony rootkit.


 

Legal Action

Electronic Frontier Foundation,
Sony BMG Litigation Info
http://www.eff.org/IP/DRM/Sony-BMG/
EFF’s site is a resource for consumers whose computers were harmed by the Sony rootkit.  The page includes background information, Sony’s response, and information about claim settlement.  It also has a helpful FAQ section for consumers interested in learning more about the settlement.

This article gives background on the class action suits and the settlement.

Dr. Michael Geist
(Canada Research Chair of Internet and E-commerce Law at the University of Ottawa),
“Sony Rootkit Settlement Leaves Canadian Consumers Unsettled”
http://www.michaelgeist.ca/content/view/1443/159/
Geist highlights the differences between the American and Canadian settlements, noting that Canadian consumers will receive considerably less and that the Canadian settlement has no provision for injunctive relief.  Geist argues that differences between the Canadian and American regulatory and legal systems should not lead to substantially different outcomes in this case.


 

Academic Perspectives

J. Alex Halderman and Ed Felten
(Princeton University),
“Lessons from the Sony DRMA Episode,”
February 14, 2006
http://www.copyright.gov/1201/2006/hearings/sonydrm-ext.pdf
Computer scientists Halderman and Felten present a technical analysis of the Sony rootkit software, examining the design choices faced by the company and their consequences.  They argue that DRM systems are “mostly ineffective at controlling uses of content” and that DRM system design is only weakly connected to the rules of copyright law.  Instead, they argue, vendor and label business models more primarily dictate the structure and implementation of DRM systems.  

Doug Lichtman
(The University of Chicago Law School),
“SonyBMG’s DRM Mistake,”
December 13, 2005
http://uchicagolaw.typepad.com/faculty/2005/12/sonybmgs_drm_mi.html
In response to comments by EFF’s Fred Von Lohmann, Professor Lichtman argues that without DRM, the music industry would have little incentive to invest in music and might instead develop more extreme mechanisms to fight piracy, such as streaming music only to compliant players that protect the music.  He also argues that self-help technologies such as DRM can reduce the costs of legal regimes.  

Randy Picker
(The University of Chicago Law School),
“Adding Mistrust to Digital Rights Management,” February 17, 2006
http://uchicagolaw.typepad.com/faculty/2006/02/adding_mistrust.html - more
Working from the Sony rootkit and broadcast flag examples, Professor Picker argues that meaningful DRM may need to be identity based, meaning that the identity of the purchaser can be gleaned from the content itself.  He recognizes that cooperation between the content providers and professional decryptors is dangerous for consumers and argues that we may need to give content purchasers reasons to be reluctant to deal with professional decryptors, thereby adding “mistrust” to DRM schemes.

Natali Helberger
(Associate Professor at the Institute for Information Law, University of Amsterdam),
“The Sony BMG Rootkit Scandal,”
September 1, 2006
http://www.indicare.org/tiki-read_article.php?articleId=165
Helberger notes that the California and EFF Sony litigation are some of the first to use consumer protection law as a way of combating DRM.  The article discusses Sony’s End User License Agreement (EULA) and the ways in which state unfair competition law can be used as an additional possible remedy against DRM misuse, along with traditional copyright law.

Professor Ed Felten and J. Alex Halderman
Comment to Copyright Office
(represented by Deirdre Mulligan, Director of Samuelson Law Technology, & Public Policy Clinic and Aaron Perzanowski, Samuelson Clinic Fellow),
“Exemption to Prohibition on Circumvention of Copyright Protection Systems for Access Control Technologies,” December 1, 2005
http://www.freedom-to-tinker.com/doc/2005/dmcacomment.pdf
In these comments to the Copyright Office, Felten and Halderman argue that the DMCA should exempt circumvention of technical protection measures for sound recordings and audiovisual works, where the protection measures create or exploit security vulnerabilities on users’ computers.  Using the Sony incident as an example, they argue that these types of DRM force consumers to choose between accepting “intolerable security risks in order to access lawfully purchased CDs” or circumventing the protection measures “in order to gain lawful access and maintain a safe computing environment.”


Interoperability Concerns about DRM Technologies


Interoperability Initiatives

The Marlin Developer Community
“In January 2005, five companies formed the Marlin Joint Development Association (JDA) to develop DRM specifications that provide interoperability across multiple multimedia devices and services. . . . The MDC’s mission is twofold – to develop specifications for an interoperable DRM platform for multimedia service, device and content providers, and to provide open access to these specifications to drive market adoption.”
http://www.marlin-community.com/

Coral Consortium
“The Consortium's goal is to create a common technology framework for content, device, and service providers, regardless of the DRM technologies they use. This open technology framework will enable a simple and consistent digital entertainment experience for consumers.”
http://www.coral-interop.org/main/calltoaction.html

Digital Media Project
“The DMP is a not-for-profit organisation with the mission to promote continuing successful development, deployment and use of Digital Media that respect the rights of creators and rights holders to exploit their works, the wish of end users to fully enjoy the benefits of Digital Media and the interests of various value-chain players to provide products and services, according to the principles laid down in the Digital Media Manifesto.”
http://www.dmpf.org/

Reasons to Love Open-Source DRM
April 3, 2006
Eliot Van Buskirk, Wired reporter
“[T]he very idea of using open-source software to enforce digital rights management runs counter to everything commonly assumed about the technology: that it needs to be secret, obscure, proprietary. But open-source DRM is exactly what Sun Microsystems has proposed, with its DReaM initiative. Its goal is to promulgate an open-source architecture for digital rights management that would cut across devices, regardless of the manufacturer, and assign rights to individuals rather than gadgets.”

The industry’s idea of a ‘perfect’ DRM scheme is one that is not controlled by either Apple or Microsoft, and which gives only them (the record industry) complete control over what users can do with their downloads. Such a scheme does not exist, and it does not exist because it isn’t possible.”

March 17, 2006
Associated Press
“According to the latest amendments, however, copy-protection technologies like Apple's exclusive FairPlay format and Sony's ATRAC3 ‘must not result in the prevention of the effective application of interoperability.’ Companies would have to share all ‘information essential to the interoperability’ of their copy-protection formats with any rival that requests it. If they refuse, a judge can order its delivery, on pain of fines. . . . [C]onsumer groups argue that the only way to give customers real choice is to break open the restrictions. ‘It's an essential condition for consumers and for the market itself,’ said Julien Dourgnon, a spokesman for UFC-Que Choisir, France's main consumer organization.”

“In this paper we look at the problem of interoperability of digital rights management (DRM) systems in home networks. We introduce an intermediate module called the Domain Interoperability Manager (DIM) to efficiently deal with the problem of content and license translation across different DRM regimes. We also consider the threat model specific to interoperability systems, and introduce threats such as the cross-compliancy and splicing attacks. We formalize the adversary model and define security of an interoperable DRM system with respect to this adversary. We finalize by proposing detailed protocols which achieve our security requirements. In order to achieve these requirements we provide novel applications of recently proposed proxy resignature and proxy re-encryption algorithms.”

Consumer Protection: Inside of Copyright Law or Outside?


U.S. Criticism and Commentary

Joseph P. Liu,
Copyright Law’s Theory of the Consumer,
44 B. C. L. Rev. 397  (March 2003).
Liu suggests that the common perception of the consumer of copyrighted works is incomplete.  He argues that “consumption” of copyrighted works is not an entirely passive enterprise, because a non-author has independent interests in self-expression, communication, and autonomy.  Finally, Liu suggests that understanding these interests can help direct changes in copyright law.
