Author(s): Arias Cabarcos, Patricia; Sánchez-Guerrero, Rosa; Almenárez Mendoza, Florina; Díaz-Sánchez, Daniel; Marín López, Andrés Abstract: Since the advent of the digital era, the traditional TV scenario has rapidly evolved towards an ecosystem comprised of a myriad of services, applications, channels, and contents. As a direct consequence, the amount of available information and configuration options targeted at today's end consumers have become unmanageable. Thus, personalization and usability emerge as indispensable elements to improve our content-overloaded digital homes. With these requirements in mind, we present a way to combine content adaptation paradigms together with presence detection in order to allow a seamless and personalized entertainment experience when watching TV.

One of the fundamental issues is the need for better access control and identity management systems. In this context, Federated Identity Management (FIM) is identified by researchers and experts as an important security enabler, since it will play a vital role in allowing the global scalability that is required for the successful implantation of cloud technologies. However, current FIM frameworks are limited by the complexity of the underlying trust models that need to be put in place before inter-domain cooperation. Thus, the establishment of dynamic federations between the different cloud actors is still a major research challenge that remains unsolved. Here we show that risk evaluation must be considered as a key enabler in evidencebased trust management to foster collaboration between cloud providers that belong to unknown administrative domains in a secure manner. In this paper, we analyze the Federated Identity Management process and propose a taxonomy that helps in the classification of the involved risks in order to mitigate vulnerabilities and threats when decisions about collaboration are made. Moreover, a set of new metrics is defined to allow a novel form of risk quantification in these environments. Other contributions of the paper include the definition of a generic hierarchical risk aggregation system, and a descriptive use-case where the risk computation framework is applied to enhance cloud-based service provisioning.

Eco-driving has acquired great importance in recent years because it is a way to reduce energy consumption that can be applied to any type of vehicle. However, for these rules to be applied requires a process of continuous learning and motivation. For this reason, many eco-driving assistants have emerged. The problem of these assistants is that they are dependent on the model of vehicle, expensive and imprecise. In this context, this paper presents a novel efficient driving assistant that uses the features of the Smartphone to accurately model the driver's driving style from the point of view of energy consumption and generate eco-driving tips to correct the bad driver's driving habits Tue, 31 May 2011 22:00:00 GMT http://hdl.handle.net/10016/13091 2011-05-31T22:00:00Z http://hdl.handle.net/10016/13090 Title: Analysis of the latest trends in mobile commerce using the NFC technology Author(s): Jovanovic, Mateja; Muñoz-Organero, Mario Abstract: The aim of this research is to propose new mobile commerce proximity payment architecture, based on the analysis of existing solutions and current and future market needs.
