Investigation of Third Party Rights Service
and Shibboleth Modification to Introduce the Service

Master's thesis; advisor: S.W. Smith.
Shibboleth is an architecture to support inter-institutional sharing
of electronic resources that are subject to access control. Codifying
copyright in Shibboleth authorization policies is difficult because of
the copyright exceptions which can be highly subjective. Third Party
Rights Service is a high-level concept that has been suggested as a
solution to approximate the exceptions of copyright law. In this
thesis, I investigate the components of the Third Party Rights
Service. I design and analyze a modified Shibboleth architecture
based on these components. The resulting architecture allows for the
phased addition of the resources to make use of the Third Party
Rights Service, while keeping the existing resources in Shibboleth.
