AB Privacy is a very complex and subjective conceptwith different meaning to different people. The meaning depends on the context. Moreover, privacy is close to the userinformation and thus, present in any ubiquitous computing scenario. In the context of identity management (IdM), privacyis gaining more importance since IdM systems deal withservices that requires sharing attributes belonging to users’identity with different entities across domains. Consequently,privacy is a fundamental aspect to be addressed by IdM toprotect the exchange of user attributes between services andidentity providers across different networks and securitydomains in pervasive computing. However, problems such asthe effective revocation consent, have not been fully addressed.Furthermore, privacy depends heavily on users andapplications requiring some degree of flexibility. This paperanalyzes the main current identity models, as well as theprivacy support presented by the identity managementframeworks. After the main limitations are identified, we propose a delegation protocol for the SAML standard in orderto enhance the revocation consent within healthcare scenarios.
