Introduction

The Digital Millennium Copyright Act (DMCA) is a large and complex law. The technologies it regulates are also themselves complex. Hard as they are to understand, both the DMCA and the copyright management systems (CMS) it regulates have potential far reaching effects on freedom of speech, fair use, consumer privacy and information security.

My goal is to make both the DMCA and CMS more comprehensible to non-lawyers and non-technologists alike. Parts of this Act are currently being (re)evaluated and it is therefore important to understand its implications and problems. I will focus here only on Title I of the DMCA, which deals with circumvention of CMS and copyright management information (CMI), although other sections of the law are equally worthy of attention [1].


Copyright Management Systems

What are Copyright Management Systems (CMS)?

"Copyright management systems (CMS) technologies that enable copyright owners to regulate reliably and charge automatically for access to digital works are the wave of the very near future. The advent of digital networks, which make copying and distribution of digital content quick, easy, and undetectable, has provided the impetus for CMS research and development. CMS are premised on the concept of "trusted systems" or "secure digital envelopes" that protect copyrighted content and allow access and subsequent copying only to the extent authorized by the copyright owner. Software developers are testing prototype systems designed to detect, prevent, count, and levy precise charges for uses that range from downloading to excerpting to simply viewing or listening to digital works." [2]

What are CMS used for?

This section outlines the major functions of rights management technology.  These functions include access control, use control, integrity protection, identification, usage metering, payment and copyright management. [3] Some examples of existing systems are also provided.

A. Access Control

A first set of functions are those that prevent access to and use of a work.  By controlling access one can control the use of information; if it cannot be accessed, it cannot be used. Access control can be provided at the source of the content (e.g., password protection for a web based publication) or at the level of the user or receiver of the information (e.g. devices used to decrypt or descramble a signal).  Access control can also control initial access to information (e.g. a CD-ROM which requires a one-time password to access it) or subsequent access (e.g. a shareware program that "times-out" so that it only works for a limited duration or fixed number of times).

B. Use Control

The second category of functions prevents certain uses of the work after it has been accessed. Copy protection is the most common type of use control, but control of other operations is possible.

C. Integrity Protection

A third set of functions is to prevent a work from being altered, i.e. to protect the integrity of the work.

D. Content Description and Identification - A fourth function of many rights management systems involves tagging documents or portions of documents to support identification, search and retrieval.

Persistent identifiers- For example, the Digital Object Identifier (DOI) System is a system for assigning, managing, and resolving persistent identifiers, known as "handles," for digital objects. Handles can be used as Uniform Resource Names (URNs), so no matter how a document changes or where it moves to on a network, the handle will stay the same and will allow people to find the document.
Metadata- Watermarks can be used to attach metadata (information about information) to a work. For instance, one could include metadata about a photograph -- author's address, terms of use, copyright date, info about the photographer and image-- along with the image itself. The data about the photograph would be encoded with the digital rendition and would never be lost.

Persistent identifiers and metadata can be used to support:

E. Usage Metering - A fifth set of functions allow the rightsholder to track the frequency a work is accessed, or to monitor other uses (e.g. copying), rather than to access or use.  This allows the rightsholder to obtain an audit trail of the actual usage made of a work (for billing or statistical purposes), to bill for each instance of a use or to spot violations of the terms of a license.

These methods can also be used to support "superdistribution", i.e. they can provide the rightsholder with continuing revenue regardless of who holds the copy of the work. If the original purchaser were to disseminate it further, the rights management system would provide the rightsholder with data on subsequent usage and could allow the rightsholder to receive compensation for each subsequent use. [7,8]

For example, the Tragoes RightsMarket system "is based on the concept of Useright not copy protection. Useright is the right to use content regardless of how the content was acquired... RightsMarket enabled content calls home periodically to authorize and report its use...The rightsholder can use the metering information to drive the billing process and...can also use that information to set pricing, new product development decisions, and produce new marketing and sales approaches.  The meter information is used by the rightsholder to decide on what steps to take with shrinkage (piracy). "
Another example is Softlock.com who claims that its "persistent security technology stops electronic shoplifting (piracy) not just during the initial download, but forever. Because SoftLock-enabled content can be securely sampled, electronically purchased and redistributed, SoftLock.com...keeps intellectual property secure while generating valuable marketing data and sales revenue no matter how many times the content is copied and redistributed - in fact, more copies means more data and revenue."

F.  Payment-  It is possible to enable automatic and simultaneous payment to the rightsholder for each actual use made of a work, through online transaction schemes.

For example, Copyright Direct is an electronic copyright management service (developed and operated by YBP Publishing Services) that automates permissions and purchase transactions for print and electronic content.  Linked to CyberCash, it collects payment from users and forwards payments with an activity report to rightsholders on a monthly basis.

G.  Copyright Management Systems- Any subset of the above functions have been combined in various full-blown "electronic copyright management systems". Normally, they cover more than measures preventing access or use and are intended to facilitate the trade in copyrights or copyrighted works within a networked environment.

For example, Liquid audio (LA) claims that its "Liquifier" is the only audio encoding tool which provides both anti-copy and anti-piracy protection. LA files are encrypted so that only an intended LA player can play it. LA uses digital watermarking helps to prevent piracy by providing a mechanism to identify bootleg copies of a recording. As part of the encoding process, the Liquifier embeds a watermark in the audio stream that can be decoded during playback. Even if a LA recording or, "Liquid Track", is written to a CD is still contains the traceable digital watermark that was embedded at the time of encoding. The watermark identifies copyright ownership and other information binding the Liquid Track to the creator. When the file is downloaded, an additional mark is added that uniquely identifies that particular copy of the Liquid Track and the downloaders information. LA claims that its watermarks cannot be removed without seriously degrading the sound quality of a recording. If a suspected pirate copy is obtained these watermarks can be extracted to provide an electronic audit trail for the authorities. In addition, the Liquifier imposes use controls (it is supposedly able to enable or disable writing to CD, control of how many copies are made, and expiration dates).

Other examples of CMS include: Imprimatur, Copyright Direct , IBM's cryptolopes and Tragoes RightsMarket


The Digital Millennium Copyright Act

What is the DMCA?

On October 12, 1998, Congress passed the Digital Millennium Copyright Act (DMCA), which makes major changes in U.S. copyright law to address the digitally networked environment. This section discusses the law's first title which implements the World Intellectual Property Organization (WIPO) Internet Treaties. Title I of the DMCA was intended to amend the U.S. copyright law to comply with the WIPO Copyright Treaty and the WIPO Performances and Phonograms Treaty (adopted at the WIPO Diplomatic Conference in December 1996).

Two of the major provisions in the WIPO treaties require legal remedies against circumventing technological protection measures and tampering with copyright management information. To comply with these provisions, the DMCA adds a new chapter, Chapter 12, to Title 17 of the United States Code. Many scholars have commented that the DMCA goes above and beyond what was necessary to comply with WIPO, that it is overreaching and skewed in favor of rightsholder interests. [9,10].

What is the history of the DMCA?

The history of the DMCA is an interesting one and sheds light on why the Act appears to be skewed in favor of media industry interests. Samuelson suggests that "the battle in Congress over the anti-circumvention provisions of the DMCA was a battle between Hollywood and Silicon Valley." [11] The history of the Act illuminates why certain exceptions were made and who they were made for.


What the DMCA Says and Why it is Problematic

SECTION 1201- CIRCUMVENTION OF COPYRIGHT PROTECTION SYSTEMS

The "Anti-Circumvention" provision

The Digital Millennium Copyright Act of 1998 states that "[n]o person shall circumvent a technological protection measure that effectively controls access to a work protected under this title." [13]

To 'circumvent a technological measure' means to "descramble a scrambled work, to decrypt and encrypted work, to otherwise avoid bypass remove deactivate or impair a technological measure, without the authority of the copyright owner"
And a 'technological measure' "effectively controls access to a work or otherwise to avoid bypass remove or deactivate or impair a technological measure without the authority of the copyright owner"

It is important to note that this provision applies to the act of circumvention in general, regardless of whether or not the circumvention infringes any protected property rights. [14] Effectively, accessing to the protected work itself, even without the intent to commit copyright infringement, is enough to trigger this provision and its penalties.

This prohibition on unauthorized access takes effect two years after enactment on the DMCA. Over this two year period, the Librarian of Congress is to conduct an "on the record" rulemaking proceeding to determine what the potential harm and benefits of this provision are and if any classes of work should be exempted from this rule.

The "Anti-Device" provision

The act states that no person can "manufacture, import, offer to the public, provide or otherwise traffic in any technology, product, service, device, component, or part thereof, that is primarily designed or produced for the purpose of circumventing a technological measure that effectively controls access to a work." [15]

In an attempt to ensure that legitimate multipurpose devices can continue to be made and sold, the prohibition applies only to those devices that:

(1) are primarily designed or produced for the purpose of circumventing;
(2) have only a limited commercially significant purpose or use other than to circumvent; or
(3) are marketed for use in circumventing.

Unlike the prohibition on acts of circumvention, which takes effect in two years, the prohibition on the manufacture and distribution of circumvention devices takes effect immediately.

Problems with section 1201:

Rights (supposedly) Not Affected

The DMCA states that nothing in section 1201 should affect the rights and limitations of existing copyright law, the "rights, remedies, limitations, or defenses to copyright infringement, including fair use". [22] Nor does it lessen or expand the existing doctrines of "vicarious and contributory liability" [23]

Problems:

Rights management technologies may reverse the Internet trend toward access rights and reset the balance in favor of exclusion. This shifting of the rights allocation may significantly abridge the three doctrines that had guaranteed access rights under copyright law: public domain, first sale and fair use. [24]

Exceptions to 1201

After lobbying by libraries, the high- tech industry and other affected parties and after intervention by the Commerce committee, Congress recognized that there may be legitimate reasons for circumvention. In response, Congress provided a number of exceptions to the prohibition on circumvention and circumvention devices. The seven exemptions reflect a wide range of specialized concerns.

While the exemptions respond narrowly to a variety of concerns, they do not address the most fundamental problem. This is that the anti-circumvention provisions will prohibit anyone from using works protected by technological measures without permission, even for privileged purposes. Below, I provide some examples of legitimate uses not covered by the exceptions. To remedy the gaps in protection of legitimate uses, Samuelson has suggested that there is a need for "or other legitimate purposes" exception to access control rule. [28]

This section describes the exceptions that were adopted and some of their implications and shortcomings.

Nonprofit libraries, archives, and educational institutions The first of these exemptions gives nonprofit libraries, archives, and educational institutions a "shopping privilege", which permits them to gain access to a work without authorization, in order to "make a good faith determination" of whether to purchase the work, and only when circumvention is the only way to make that determination. [29]

Problems:

Exception for Law Enforcement and Intelligence Activities. The DMCA permits circumvention for any lawfully authorized investigative, protective, or intelligence activity by or at the direction of a federal, state, or local law enforcement agency, or of an intelligence agency of the United States.[32]

Reverse Engineering Exception allows software developers to circumvent technological protection measures of a lawfully obtained computer program in order to identify the elements necessary to achieve interoperability of an independently created computer program with other programs. A person may reverse engineer the lawfully acquired program only where the elements necessary to achieve interoperability are not readily available and reverse engineering is otherwise permitted under the copyright law. Furthermore, a person may develop and employ technological means to circumvent and make available to others the information or means for the purpose of achieving interoperability. [33]

Problems:

Encryption Research Exception. Congress provided an encryption research exception intended to advance the state of knowledge in the field of encryption technology and to assist in the development of encryption products. Circumvention in the course of "good faith encryption research" may be allowed if the following conditions are met [37]:

(1) the researcher lawfully obtained the copyrighted work;
(2) circumvention is necessary for the encryption research;
(3) the researcher made a good faith effort to obtain authorization from the copyright owner before the circumvention; and
(4) circumvention is otherwise permissible under the applicable laws.

In addition to the above factors, the DMCA directs the court to consider three other factors:
(1) whether the information derived from the research was disseminated to advance the knowledge or development of encryption technology or to facilitate infringement;
(2) whether the researcher is engaged in a legitimate course of study, is employed, or is appropriately trained or experienced in the field of encryption technology; and
(3) whether the researcher timely notifies the copyright owner with the findings and documentation of the research.

A person may provide the means to develop technical protection systems to a collaborator for the sole purpose of performing "good faith" encryption research.

Problems:

Security Testing Exception. In addition to the encryption research exception, the DMCA provides a security testing exception, which permits circumvention conducted in the course of security testing if it is otherwise legal under applicable law. Security testing is defined as "obtaining access, with proper authorization, to a computer, computer system, or computer network for the sole purpose of testing, investigating or correcting a potential or actual security flaw, or vulnerability or processing problem."

In determining whether this exception is applicable, the DMCA requires the court to consider whether the information derived from the security testing was used solely to improve the security measures or if it was used to facilitate infringement. The DMCA also permits the development, production or distribution of technological means for the sole purpose of performing permitted acts of security testing. [38]

Problems:

Exception Regarding Minors. The DMCA permits the manufacture of technologies whose "sole purpose is to prevent the access of minors to materials on the Internet" as long as they are not included in a product which does not itself violate the provisions of Title I. [40]

Problem: This is yet another example of an exception that is too narrowly tailored to cover all legitimate uses:

Protection of Personally Identifying Information. The DMCA addresses personal privacy concerns by allowing people to circumvent a technical measure if the technical measure collects or disseminates personally identifying information about a user's online activities. This exception is only applicable and only if disabling data collection or dissemination is the sole effect of the circumvention. This exception is only applicable if the user is not provided with adequate notice and the capability to prevent or restrict such collection or dissemination. [41, 42]

Problems:

Certain Analog Devices and Certain Technological Measures. The last exemption requires home VCRs to conform to two forms of copy control technology (the automatic gain control technology and the colorstripe copy control technology) that will permit owners of video programming to lock certain programming and prerecorded movies. The exemption prohibits use of this locking technology for video signals transmitted over the air and over channels transmitted on cable as part of the basic service tiers. This provision prohibits tampering with these analog copy control technologies to render them ineffective by redesigning of video recorders or by intervention of "black box" devices or "software hacks." This provision becomes effective in eighteen months. [43]


SECTION 1202- COPYRIGHT MANAGEMENT INFORMATION

The DMCA prohibits tampering with copyright management information (CMI). Specifically, the DMCA creates liability for any person who intentionally provides or distributes false CMI. Also, the DMCA prohibits intentional removal or alteration of CMI or knowing distribution of illegally modified CMI. To be covered by the DMCA, CMI must be "conveyed in connection" with a copyrighted work and CMI may constitute any of the following:

(1) information that identifies the copyrighted work, including the title of a work, the author, and the copyright owner;
(2) information that identifies a performer whose performance is fixed in a work, with certain exceptions;
(3) in case of an audiovisual work, information that identifies the writer, performer, or director, with certain exceptions;
(4) terms and conditions for use of the work;
(5) identifying numbers or symbols that accompany the above information or links to such information, for example, embedded pointers and hypertext links; or
(6) other information as the Register of Copyrights may prescribe by regulation

However, there is an exception to protect the privacy of users. The term CMI does not include "any personally identifying information about the user of a work", nor can regulation require that CMI contain such information. [44]

Problems with 1202:

Because the definition of CMI includes "terms and conditions for use of the work" and "identifying numbers or symbols that accompany the above information", the definition is broad enough to cover CMI which would also control access to a work (e.g., CMI that instructs trusted hardware to control uses of the work). In this case, tampering with a CMI might therefore violate both sections 1201 and 1202.

Civil Remedies and Criminal Penalties

The DMCA creates civil remedies and criminal penalties for violations of Sections 1201 or 1202. A civil action may be brought in a federal district court. The court has broad powers to grant injunctions and award damages, costs and attorney's fees. The court may also order the impounding, the remedial modification or the destruction of the devices or products involved in the violation. The court may punish repeat offenders by awarding treble damage awards. Generally, it is up to the court to decide whether to reduce damage awards against innocent violators. But, in the case of nonprofit library, archives or educational institutions, the court must remit damages if it finds that a qualifying entity had no reason to know of the violation. The DMCA prescribes significant criminal penalties for violations committed "willfully and for the purposes of commercial advantage or private financial gain." Criminal penalties are inapplicable to nonprofit libraries, archives, and educational institutions. The civil remedies and sanctions are available irrespective of the state of mind or knowledge of the person circumventing the technological protection measure. Both criminal and civil sanctions apply to circumvention per se, whether or not the underlying use is privileged. [46]


Legal and Technical Solutions-

[1] The changes to copyright law have significant implications for libraries, archives, and institutions of higher education. Of particular importance, is the fact that sections of the DMCA contain detailed regulations for online service providers that must be followed to obtain protection from liability for infringement. Educational institutions are expected to educate their communities about copyright law and compliance. Other portions of the law will require the community to develop processes for collecting information and conducting studies to ensure the long-term protection of fair use and other copyright exceptions.

[22] The basic analysis for direct copyright infringement is relatively straightforward and rooted in a well-settled federal statutory scheme. Under Section 106 of the Copyright Act, courts examine whether one or more of the copyright owner's five exclusive rights have been violated. These include the reproduction right, the derivative works right, the distribution right, the performance right, and the display right. See 17 U.S.C. Section 106. If infringement is found, the next step in the analysis often centers on whether this infringement constitutes fair use under Section 107.

[23] Contributory infringement originated in tort law and stems from the notion that one who directly contributes to another's infringement should be held accountable. Judicially created by analogy to patent law, it has been deemed applicable today in the areas of copyright, patent, and trademark. Acts of contributory infringement generally fall into one of two categories: (1) personal conduct that contributes and thus furthers direct infringement, or (2) contribution of a 'machine or good' which provides a means to infringe.
