Preserving Data Privacy in eHealth

Privacy of data is a crucial aspect in nowadays life, from economy to leisure, from public administration to healthcare. Specification, authoring, and validation of appropriate policies are the basis for the sound application of such policies during the subsequent enforcement phase. This chapter reviews different components in a framework for privacy policy management and specifically focuses on the e-health scenario. Starting from different existing approaches to policy authoring and policy validation, we then focus on a specific solution aiming at integrating three tools covering the whole phase of policy generation, i.e., a user-friendly authoring tool allowing definition of privacy preferences in natural language, a formal analysis tool to detect conflicts among policies, and a conflict solver implementing a solution strategy that privileges the most specific policy among a set of conflicting ones.
