Portable secure identity management for software engineering

Identity management refers to authentication, sharing of personally identifiable information (PII) and provision of mechanisms protecting the privacy thereof. The most commonly implemented is federated authentication, permitting users to maintain a single set of credentials to access many services. Specifications exist for profile exchange between a service provider (SP) and the identity provider (IdP), but are rarely used. Most frequently, local storage of profile data is utilised due to security and privacy concerns. Key work in this area includes that of the PRIME project, which provides privacy enhancing identity management. Their work utilises local data stores and/or trusted third parties.
