LicenseScript: A Novel Digital Rights Language and its Semantics

Proceedings of the 11th international conference on Artificial intelligence and law - ICAIL '07, 2007

Digital contents distributed over the internet are regulated by law and by technical management systems. The latter include a semantic component that describes licenses, i.e. rights of use which are granted to the user. These elements of Digital Rights Management (DRM) systems are called Rights Expression Languages (REL), they gather terms and relations needed to build licenses. Some are based on an ontology of online licenses, not necessarily related to applicable law and various legal systems, and cannot interoperate. As a consequence, there is a need for a more generic way to express licenses. Here, generic means that rightholders should only need to express the license they need once, and semi-automatic tools should then translate this license so it can be browsed by any specific system. Hence it implies the necessity to be able to model concept semantics in order to translate a license expressed in generic terms into more specific terms that are compliant with the specific standards used by distribution systems. This work comes as part of larger studies on legal ontologies, legal systems and RELs.

The project LicenseScript develops and demonstrates an integrated framework for analysis and design of secure information delivery systems. The contributions of this project are the demonstration of new analysis and design methods in at least two of the following concrete application areas: (1) Digital Rights Management (DRM), (2) wireless sensor networks (WSNs), (3) privacy protection.

In the digital world protecting digital intellectual property is proving to be a hard task. Not only it is complex to provide robust and reliable mechanisms to prevent unauthorized content copying and utilization, but also it is complex to provide a mechanism for specifying and enforcing how content can and will be used. Rights expression languages allow content providers and distributors to syntactically and semantically to express a set of rights that are associated to a digital object. In this paper we will provide the definition and description of the digital object license granting rights life cycle management and processes necessary to secure the license throughout this entire life cycle.

The Digital Rights Management (DRM) systems aim at protecting and enforcing the legal rights associated with the use of digital content distributed on the Internet. Most of such systems use watermarking techniques to implement the content protection. Although the effectiveness of the implemented protection strictly depends on the adopted watermarking techniques, an important role is also played by watermarking protocols. They define the scheme of the interactions that have to take place among the entities involved in the processes of content protection and web-based distribution governed by the DRM systems. This paper presents a DRM system developed as a web software platform to implement the copyright protection of multimedia digital content distributed on the Internet. The DRM system is based on a watermarking protocol previously developed by the authors, and has been designed as a service oriented architecture composed of a federation of coordinated web entities that play distinct roles and interact within a trusted environment.

Digital Rights Management Systems (DRMS) are seen by content providers as the appropriate tool to, on the one hand, fight piracy and, on the other hand, monetize their assets. Although these systems claim to be very powerful and include multiple protection technologies, there is a lack of understanding about how such systems are currently being implemented and used by content providers.
