A Meta-Data and Reasoning Framework for Open Assertion and Evidence Exchange and Query

We provide a framework and architecture for enhancing the privacy and openness of identity management systems. We propose that anonymous credential systems may be used as cryptographic mechanism to satisfy legal and social requirements for both privacy and security within identity management systems. We outline the use cases and requirements for integrating anonymous
credential systems into our framework and architecture. We propose an ontology-based meta-data model for satisfying these requirements and show how this can be applied to the use cases. We also discuss a security model for the use of ontologies within this model.
