Policy-Based Integration of User and Provider-Sided Identity Management

  • Wolfgang Hommel
Part of the Lecture Notes in Computer Science book series (LNCS, volume 3995)


Depending on whether the users or the providers are performing it, Identity Management (IM) traditionally has different meanings. For users, IM means to choose between one’s own identities and roles, in order to make selected personal information available to providers under privacy aspects. For providers, IM typically consists of centralized identity data repositories and their use by the offered services. Methods and tools for both aspects of IM have developed almost orthogonally, failing to consider their interoperability and complementary purposes. We analyze the similarities between both IM aspects and demonstrate how both sides can benefit from the use of a common policy language for personal information release and service provisioning. We derive criteria for this common policy language, demonstrate XACML’s suitability and discuss our prototype for the Shibboleth IM system.
