This article introduces a privacy framework for Smart Homes, supporting individuals roaming freely in pervasive computing environments. Such environments typically are equipped with different kinds of sensors and tracking devices for context-aware service provisioning. While on the one hand, people want to take advantage of the comfort and added value of(More)
The pervasive nature of future living environments, saturated with sensors and context-detecting services, pose a completely new challenge for computer science: the art of virtual disappearance. In many situations individuals do not want to be tracked by the environment and do not want their where abouts to be known publicly or even by their friends and(More)
Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and interesting properties which overcame some of the inconveniences found on traditional gas sensors appeared over two decades ago. Thanks to(More)
One distinctive feature of pervasive computing environments is the common need to gather and process context information about real persons. Unfortunately , this unavoidably affects persons' privacy. Each time someone uses a cellular phone, a credit card, or surfs the web, he leaves a trace that is stored and processed. In a pervasive sensing environment,(More)
In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid sodium salt) (PAA) was prepared and subsequently thin films were fabricated by the dip-coating technique using glass slides as substrates.(More)
Nowadays is very common for homes or buildings in general to have some kind of automation system for the efficient use of energy and for common comfort matters like illumination and blinds & shutters controlling, among others. It can easily add to these systems different kind of sensors for different uses like: monitoring building structure health,(More)
In this work, we introduce the Privacy Manager, a user interface designed to allow non-expert users to manage privacy in the envisioned era of pervasive computing. The Privacy Manager is part of the implementation of the User-centric Privacy Framework, which was introduced as a novel mechanism to enable personal privacy for the inhabitants of the smart(More)
