Dealing with anonymity in wireless sensor networks

Nowadays Wireless Sensor Networks (WSN) are used in many application contexts. Data handled by WSN are required to be protected for privacy reasons since they can be directly or indirectly related to individuals. The problem of preventing the identification of individuals starting from their data, known as anonymity, is a fundamental requirement for privacy aware systems.
 This paper proposes a solution to guarantee anonymity for a wide spread type of WSN by means of privacy policies. The solution is based on a UML model that introduces the conceptual elements and guidelines that are needed to build privacy policies for WSN.
