Abstract	E very day, new ubiquitous systems are being developed and integrated into our daily routines, whose presence is sometimes not even perceived by the casual user. The aim of this work is to investigate questions of security and privacy in ubiquitous and context aware computing. Using a prototype for interactive television — TV-I (Goularte, 2003) — that has characteristics of mobility and contextual-awareness, this work defines a set of basic requirements that are fundamental in order to guarantee security and privacy in ubiquitous systems. Furthermore, this work uses contextual information in order to dynamically manage security and privacy requirements according to security and privacy policies that are expressed in the EPAL language. In order to validate the experimental results, a Security Manager has been implemented as a service of the TV-I prototype. The principal characteristic of this manager is to enforce access control over the personal information using contextual information of the ubiquitous system, and which is supplied via the Context Manager, designed by Santos (2004).
