    El objetivo principal del trabajo presentado en esta tesis es el de describir la definición de mecanismos de interoperabilidad entre lenguajes de expresión de derechos y lenguajes de políticas. Empezando con la interoperabilidad entre lenguajes, se quiere ir un paso más allá y definir cómo servicios para la gestión de contenidos multimedia pueden interoperar por medio de arquitecturas estándares orientadas a servicios.Para conseguir este objetivo, varios estándares e iniciativas existentes se van a analizar y ser tenidas en cuenta. Respecto a los lenguajes de expresión de derechos y de políticas, se han considerado estándares tales como MPEG-21 Rights Expression Language (REL), Open Digital Rights Language (ODRL) y eXtensible Access Control Markup Language (XACML). Respecto a los servicios para la gestión del contenido multimedia, se han considerado la plataforma Multimedia Information Protection And Management System (MIPAMS), una implementación de una arquitectura basada en estándares, y el estándar Multimedia Service Platform Technologies (MSPT), también conocido como el estándar MPEG-M. La contribución de esta tesis se divide en dos partes, una dedicada a la interoperabilidad entre lenguajes y la otra dedicada a la interoperabilidad entre services, ambas dirigidas a la gestión de contenido multimedia. Se describen a continuación.La primera parte de la contribución describe cómo MPEG-21 REL, ODRL y XACML pueden interoperar, definiendo los mecanismos para traducir expresiones de lenguaje a lenguaje. Los mapeos proporcionan distintos niveles de granularidad, empezando por un mapeo basado en una solución programática basada en diagramas realizados con lenguajes de modelado de alto nivel como pueden ser Unified Modelling Language (UML) y Entity-Relationship (ER). El siguiente nivel de mapeo incluye mapeos específicos entre MPEG-21 REL y XACML y ODRL y XACML. Finalmente, se plantea una solución más general con el uso de un bróker. Parte de este trabajo se ha realizado en el contexto de la Red de Excelencia VISNET-II y del Proyecto Integrado AXMEDIS. Los resultados obtenidos avalan la validez de los métodos de interoperabilidad descritos.La segunda parte de la contribución describe cómo definir standards based building blocks (SB3) para proporcionar interoperabilidad entre servicios para la gestión del contenido multimedia. Esta definición se basa en el análisis de casos de uso existente para la gestión de contenido, desde los que necesitan menos seguridad sobre el contenido gestionado hasta los que requiere una gestión completa de los derechos digitales (DRM, digital rights management), incluyendo técnicas de control de acceso y cifrado, para soportar gestión segura del contenido. En esta sección también se presenta el trabajo realizado en los proyectos de investigación AXMEDIS, Musiteca y Culturalive. Además, se describe el trabajo de estandarización realizado en MPEG-M, especialmente en Elementary Services y Service Aggregation. Para demostrar el uso de ambas tecnologías se presenta una aplicación móvil que integra MPEG-M y MIPAMS.Además, se presentan las conclusiones y las líneas de trabajo futuro en la sección correspondiente, junto con las publicaciones asociadas a esta tesis, que se describen en el documento. En resumen, el trabajo presentado puede seguir diversas líneas de investigación. Por un lado, es necesario estudiar las nuevas versiones de los lenguajes de expresión de derechos y políticas aparecidos recientemente. Además, también habrá que tener en cuenta el lenguaje de expresión de contratos, MPEG-21 CEL, estandarizado recientemente, con el objetivo de evaluar la interoperabilidad con los lenguajes de expresión de derechos y políticas. Por otro lado, se deben seguir distintas iniciativas de estandarización para completar el mapa de SB3¿s, considerando estándares MPEG y otros no sólo relacionados con multimedia sino también con otros escenarios de aplicación como e-salud y e-gobierno.

    The main goal of the work presented in this thesis is to describe the definition of interoperability mechanisms between rights expression languages and policy languages. Starting from languages interoperability, the intention is to go a step further and define how services for multimedia content management can interoperate by means of service-oriented generic and standardised architectures. In order to achieve this goal, several standards and existing initiatives will be analysed and taken into account. Regarding rights expression languages and policy languages, standards like MPEG-21 Rights Expression Language (REL), Open Digital Rights Language (ODRL) and eXtensible Access Control Markup Language (XACML) are considered. Regarding services for content management, the Multimedia Information Protection And Management System (MIPAMS), a standards-based implemented architecture, and the Multimedia Service Platform Technologies (MSPT), also known as MPEG-M standard, are considered. The contribution of this thesis is divided into two parts, one devoted to languages interoperability and the other one devoted to services interoperability, both addressed to multimedia content management. They are briefly described next. The first part of the contribution describes how MPEG-21 REL, ODRL and XACML can interoperate, defining the mapping mechanisms to translate expressions from language to language. The mappings provided have different levels of granularity, starting from a mapping based on a programmatic approach coming from high-level modelling diagrams done using Unified Modelling Language (UML) and Entity-Relationship (ER). The next level of mappings includes specific mappings between MPEG-21 REL and XACML and ODRL and XACML. Finally, a more general solution is proposed by using a broker. Part of this work was done in the context of the VISNET-II Network of Excellence and the AXMEDIS Integrated Project. The findings done prove the validity of the interoperability methods described. The second part of the contribution describes how to describe standards based building blocks to provide interoperable services for multimedia content management. This definition is based on the analysis of existing content management use cases, from the ones involving less security over multimedia content managed to the ones providing full-featured digital rights management (DRM) (including access control and ciphering techniques) to support secure content management. In this section it is also presented the work done in the research projects AXMEDIS, Musiteca and Culturalive. It is also shown the standardisation work done for MPEG-M, particularly on elementary services and service aggregation. To demonstrate the usage of both technologies a mobile application integrating both MPEG-M and MIPAMS is presented. Furthermore, some conclusions and future work is presented in the corresponding section, together with the refereed publications, which are briefly described in the document. In summary, the work presented can follow different research lines. On the one hand, further study on rights expression languages and policy languages is required as new versions of them have recently appeared. It is worth noting the standardisation of a contract expression language, MPEG-21 CEL, which has also to be further analysed in order to evaluate its interoperability with rights and policy languages. On the other hand, standard initiatives must be followed in order to complete the map of SB3's, considering MPEG standards and also other standards not only related to multimedia but also other application scenarios, like e-health or e-government.

    Currently, there are several ways of describing and referring to images in RDF. This ambiguity results in a proliferation of vocabularies for image descriptions, complicating the cross-community data integration of information related to digital images. In addition, there are no standardized guidelines on how to integrate RDF data into the image metadata. Therefore, the JPEG standardization committee has recently initiated some activities to streamline the integration of images in the cloud of Linked Data. One effort is the standardization of an ontology for describing digital images. JPEG aims at providing a technology that enables the uniform description of photos and videos with technical, administrative and semantic metadata compliant with the RDF specification and the principles of Linked Data. Secondly, specifications to integrate RDF data into JPEG images are elaborated. Finally, since descriptions often only apply to a certain part of an image, a last effort is to formalize the specification of regions of interest. In this paper, members of the JPEG committee provide a detailed overview of these ongoing activities. © 2013 Springer-Verlag.

    The research around visual search is gaining relevance due to the evolution in the generation and usage of digital images. A significant push comes from the mobile visual search topic, due to the widespread proliferation of camera enabled mobile devices. The new scenarios are increasing the urgency of novel solutions for challenging problems such as the efficient coding of compact visual descriptors and the interoperability of distributed visual search query interfaces. Currently, almost every visual search service offers a different retrieval interface and image metadata description format, preventing unified and efficient access. In this context, standardization groups such as ISO/IEC SC29/WG11 (MPEG) and ISO/IEC SC29/WG1 (JPEG) have been working to create unified interfaces for image repositories. In one hand, MPEG provides the ISO/IEC 15938-12 (MPEG Query Format, MPQF), which standardizes a query language for multimedia repositories and has also started an activity for standardizing compact descriptors for visual search (CDVS). On the other hand, JPEG is now finishing the ISO/IEC 24800 (JPSearch), which provides solutions to the image metadata interoperability problem. This paper analyzes how these standardization activities can be combined to satisfy the requirements posed by the mobile visual search scenario, which are their limitations and which are the necessary actions to be taken by the standardization committees in order to overcome them.

    Controlling, protecting and managing access to multimedia content could be a difficult task if a system was not prepared for it. To solve this situation minimizing the impact on the existing system, we propose the use of a modular architecture which provides digital rights and privacy policies management features. It can be integrated just invoking some web service calls, depending on which services are needed. To show its use, we present several scenarios where we have successfully integrated it, like distribution of content for digital terrestrial television broadcasting and access to personal health information.

    New mobile devices (pda’s, tablets) permit the implementation of new business models as they are always connected and provide multimedia capabilities for capturing images, videos, music or even conversations. Together with an architecture for the secure management and distribution of multimedia content called MIPAMS, we propose a mobile business model with the implementation of a mobile application based on iOS (Apple operating system for mobile devices) for publishing added value content captured with a mobile device.

    This paper describes several scenarios for the management of digital media, focusing on electronic publishing from mobile environments. The solution proposed in those scenarios is based on MIPAMS (Multimedia Information Protection And Management System), a service-oriented Digital Rights Management (DRM) platform, which enables the creation, registration and distribution of multimedia content in a secure way, respecting intellectual property rights. The particularity of the mobile scenario with respect to others is the limited capability of mobile devices. A specific use case has been identified for the mobile environment and a new system, based on MIPAMS, has been designed for the electronic publishing environment.

    There are several initiatives working in the definition and implementation of distributed architectures that enable the development of distributed multimedia applications on top of them, while offering Digital Rights Management (DRM) features. In this chapter, the main features of the MPEG Extensible Middleware (MXM) (ISO/IEC, http://mxm.wg11.sc29.org, 2010) and the new Advanced IPTV terminal (AIT) (ISO/IEC, ISO/IEC JTC1 SC29/WG11 N11230, 2010), which together will form a future second edition of the MXM standard (renamed to Multimedia Service Platform Technologies) are presented. On the other hand, the DMAG’s (Distributed Multimedia Applications Group (DMAG), http://dmag.ac.upc.edu, 2010) Multimedia Information Protection and Management System (MIPAMS) (Torres et al., Springer, Heidelberg, 2006) is also presented, highlighting the common ground and differences between MIPAMS and the standards. A set of usage scenarios is also proposed to show how MIPAMS enables the development of applications, on top of it, which deal with the needs of content creators, distributors and consumers according to different business models.

    Authors of scholarly objects might fear that there is a potential risk that the original material they publish in online sites or that they submit for evaluation to scientific journals or conferences is used by others as their own material. In such cases, it would not be easy for the original authors to prove authorship of the original contribution. In similar circumstances, it is very difficult to prove the authorship or origin of some materials that are being distributed amongst social networks, private or institutional websites or any other means through the Internet, namely documents, papers, images, data, etc. Those materials can be easily plagiarised (e.g. partially or totally translated) and redistributed without any control and with no means to prove authorship. In this context, we propose an online framework for the registration, search, interchange and trade of scholarly objects, which helps to overcome the potential drawbacks of online distribution and publishing. This framework acts as an intellectual property repository and sales point, where people is able to register content and determine the way they want to trade it, while providing innovative search capabilities based on the MPEG Query Format standard [1]. Creative Commons (CC) [2] limitations are identified and overcome by means of a licensing approach that combines Rights Expression Languages and the MPEG-21 Media Value Chain Ontology [3].

    Social Networks, as the main axis of Web 2.0, are creating a number of interesting challenges to the research and standardisation communities. In this paper, we analyse the current and future use of access control policies in Social Networks. Subsequently, two main issues are addressed: the interoperability amongst systems using different policy languages and the lack of elements in the existing policy languages when trying to express Social Networks’ access control. In particular, our approach is based on the use of the XACML standard.

    The present paper describes the design and usage of an Internet medical image search engine based on the queryby-example paradigm and the multimedia standard ISO-15938-12:2008. The system, which allows combining Content Based Information Retrieval (CBIR) techniques such as “query by image” with traditional XML metadata filtering, is applied to annotate and query Optical Biopsies-OB (in the present case Confocal endomicroscopy-CEM). The OB-CEM are taken by endoscopists, not trained in microscopic morphology which is the domain of the surgical pathology. To gain diagnostic confidence the endoscopists could consult the images to a pathologist or could use the system proposed in the paper. That is, to search for similar images to compare the diagnosis.

    Digital still images are generated, distributed and stored worldwide at an ever increasing rate. Yet, the large number of available metadata description formats prevents consistent and efficient access to image repositories. Standardized solutions for unifying the access and the retrieval of image repositories are therefore strongly needed. The ISO/IEC SC29 WG1 (more commonly known as JPEG) established the JPSearch project, which aims to standardize interfaces of an abstract image retrieval framework. In this context, the paper introduces our contribution consisting of a reference metadata model, which in combination with the JPEG query format improves interoperable image retrieval for users. Second, a transformation rule declaration language for query reformulation is presented, which contributes to interoperability at the repository side.

    Context-aware applications are fast becoming popular as a means of enriching users’ experiences in various multimedia content access and delivery scenarios. Nevertheless, the definition, identification, and representation of contextual information are still open issues that need to be addressed. In this paper, we briefly present our work developed within the VISNET II Network of Excellence (NoE) project on context-based content adaptation in Virtual Collaboration Systems (VCSs). Based on the conducted research, we conclude that MPEG-21 Digital Item Adaptation (DIA) is the most complete standardization initiative to represent context for content adaptation. However, tools defined in MPEG-21 DIA Usage Environment Descriptors (UEDs) are not adequate for Virtual Collaboration application scenarios, and thus, we propose potential extensions to the available UEDs.

    We present an innovative architecture that enables the digital representation of original works and derivatives while implementing Digital Rights Management (DRM) features. The architecture’s main focus is on promoting trust within the multimedia content value networks rather than solely on content access and protection control. The system combines different features common in DRM systems such as licensing, content protection, authorization and reporting together with innovative concepts, such as the linkage of original and derived content and the definition of potential rights. The transmission of reporting requests across the content value network combined with the possibility for authors to preserve rights over derivative works enables the system to distribute income amongst all the actors involved in different steps of the creation and distribution chain. The implementation consists of a web application which interacts with different external services plus a desktop user application used to render protected content. It is currently publicly accessible for evaluation.

    In December 2008, ISO/IEC SC29WG11 (more commonly known as MPEG) published the ISO/IEC 15938-12 standard, i.e. the MPEG Query Format (MPQF), providing a uniform search&retrieval interface for multimedia repositories. While the MPQF’s coverage of basic retrieval functionalities is unequivocal, it’s suitability for advanced retrieval tasks is still under discussion. This paper analyzes how MPQF addresses four of the most relevant approaches for advanced multimedia retrieval: Query By Example (QBE), Retrieval trough Semantic Indexing, Interactive Retrieval, and Personalized and Adaptive Retrieval. The paper analyzes the contribution of MPQF in narrowing the semantic gap, and the flexibility of the standard. The paper proposes several language extensions to solve the different identified limitations. These extensions are intended to contribute to the forthcoming standardization process of the envisaged MPQF’s version 2.
