Abstract
In ubiquitous networks, the multiple devices carried by an user may unintentionally expose information about her habits or preferences. This information leakage can compromise the users' right to privacy. A common approach to increase privacy is to hide the user real identity under a pseudonym. Unfortunately, pseudonyms may interfere with the reputation systems that are often used to assert the reliability of the information provided by the participants in the network. This paper presents a framework for combining anonymity with reputation and shows that it can be configured to provide a desired degree of balance between these two conflicting goals. The proposed solution leverages on well-known cryptographic techniques, such as public key infrastructure and blind signatures
