Privacy models and languages: Assurance checking policies

Abstract

Assurance policies express the security and data protection processes and mechanisms which should be in place to protect users' data. Users define such policies to express the minimum privacy protection which they wish to have in place by the recipient of their data. Service providers publish their policies to assert protection which should be in place, and for which they are able to provide evidence that this is indeed the case. Thus, assurance policies may be regarded as a specialised form of release and data handling policy, depending upon the context. In this section we explain the motivation for using assurance policies, and show some formalisms used within PRIME. © 2011 Springer-Verlag Berlin Heidelberg.
