Alternativas para la autogestión de los derechos de autor en el mundo digital

We analyse different alternatives that are useful to ease creators the exploitation of the intellectual property of their works. More in concrete, we deal with author’s rights. We first provide a general overview of the intellectual property concept and then we describe the rights management alternatives, including collective management and self management. Next, we analyse a selected set of initiatives that enable users to self manage their intellectual property rights, by partially transferring them or by taking profit of their trade. We finally propose the mains features for a comprehensive intellectual property system and we present the results and prototypes our group has obtained and developed

Alternatives for the self-management of author rights in the digital world

We analyse different alternatives that facilitate the exploitation of intellectual property. Specifically, we deal with author’s rights. First we provide a general overview of the intellectual property concept and then we describe the rights management alternatives, including collective management and self management. Next, we analyse a selected set of  initiatives that enable users to self manage their intellectual property rights, by partially transferring them or by obtaining economic benefits in exchange. We finally propose the main features for a comprehensive intellectual property system and present the results and prototypes that our research group has obtained and developed

Reliable scholarly objects search and interchange framework

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].Peer ReviewedPostprint (published version

A mobile Scenario for Electronic Publishing based on the MIPAMS Architecture

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.Postprint (published version

A web-based rights management system for developing trusted value

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.Postprint (published version

Epidemic and Cascading Survivability of Complex Networks

Our society nowadays is governed by complex networks, examples being the power grids, telecommunication networks, biological networks, and social networks. It has become of paramount importance to understand and characterize the dynamic events (e.g. failures) that might happen in these complex networks. For this reason, in this paper, we propose two measures to evaluate the vulnerability of complex networks in two different dynamic multiple failure scenarios: epidemic-like and cascading failures. Firstly, we present \emph{epidemic survivability} ($ES$), a new network measure that describes the vulnerability of each node of a network under a specific epidemic intensity. Secondly, we propose \emph{cascading survivability} ($CS$), which characterizes how potentially injurious a node is according to a cascading failure scenario. Then, we show that by using the distribution of values obtained from $ES$ and $CS$ it is possible to describe the vulnerability of a given network. We consider a set of 17 different complex networks to illustrate the suitability of our proposals. Lastly, results reveal that distinct types of complex networks might react differently under the same multiple failure scenario

Contribution to an Architecture for Multimedia Information Management and Protection Based on Open Standards

El principal objetivo de éste proyecto de investigación es la definición de una arquitectura que permita la protección y gestión de los derechos digitales en un entorno de gestión de contenido multimedia, siguiendo estándares abiertos siempre que sea posible. A fin de conseguir dicho objetivo, se analizarán y considerarán múltiples estándares e iniciativas relacionados.En primer lugar se aborda la definición de una arquitectura preliminar basada en MPEG-21 que permite la protección y gestión de los derechos digitales (DRM) aplicables a contenido multimedia. Más adelante, se presenta una arquitectura genérica y se describen diferentes implementaciones desarrolladas en proyectos nacionales y europeos, como AXMEDIS, VISNET II, Linked-Work y GILDDA. El análisis incluye casos de uso, aspectos de seguridad y la propuesta de una metodología de prueba o test. En el caso de Linked-Work, se detalla una implementación específica, resaltando los conceptos clave que la hacen diferente de otros sistemas de DRM.The main goal of this research project is to define a generic architecture for the protection and management of digital rights in a multimedia content management scenario following open standards as much as possible. In order to achieve this goal, several standards and initiatives will be analysed and taken into account.First, a MPEG-21-based preliminary architecture for the protection and management of digital rights for multimedia content is tackled. Later on, a more general architecture is defined. Several implementations are described such as those in several Spanish and European projects such as AXMEDIS, VISNET II, Linked-Work and GILDDA. The focus in made on use cases, security features and a testing methodology. Linked-Work details a specific implementation, emphasising on the key concepts that make it different from other kind of DRM systems
