Lifelong privacy – privacy and identity management for life.

Abstract. The design of identity management preserving an individual's privacy must not stop at supporting the user in managing her/his present identities. Instead, since any kind of privacy intrusion may have implications on the individual's future life, it is necessary that we identify and understand the issues related to longterm aspects of privacyenhancing identity management. Only that way, according solutions can be developed, which enable users to control the disclosure of their personal data throughout their whole lives, comprising past, present, and future. This paper will give a general overview about concepts supporting privacyenhancing identity management. Further, it introduces the reader to the problem field of privacy management by means of privacy-enhancing identity management during various stages of life as well as in various areas of life. Statements about required mechanisms will be given as well as directions regarding the three most important aspects to consider when managing one's identities: communication infrastructure as well as selection of communication partners and tools

Security in Public Mobile Communication Networks

Introduction The increasing use of mobile communication networks results in ever more stringent security requirements. In an information society, availability, integrity and confidentiality are essential. Especially the provision of the latter is hard to demonstrate. If someone or some component is able to collect and store personal data, one cannot be sure that this data is not gathered and not (mis)used. But this "being sure" is essential with respect to privacy and data protection. Therefore, legal means alone are insufficient and have to be complemented by technical means we are going to describe in the sequel. This first part is introductory and reflects the structure of future mobile communication networks. When users communicate in such networks there is much data generated which needs to be handled in a secure way. We present data protection and security requirements which we believe are the strongest ever presented. 1.1 Structure of Future Mobile Telecommun
