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)
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)
Protection of personal data in the Internet is already a challenge today. Users have to actively look up privacy policies of websites and decide whether they can live with the terms of use. Once discovered, they are forced to make a " 'take or leave " ' decision. In future living and working environments, where sensors and context-aware services are(More)
The current digital revolution has ignited the evolution of communications grids and the development of new schemes for productive systems. Traditional technologic scenarios have been challenged, and Smart Cities have become the basis for urban competitiveness. The citizen is the one who has the power to set new scenarios, and that is why a definition of(More)
In this paper we address the realization of personal privacy control in pervasive computing. We argue that personal privacy demands differ substantially from those assumed in enterprise privacy control. This is demonstrated by introducing seven requirements specific for personal privacy, which are then used for the definition of our privacy policy language,(More)
