Abstract

The appeals for interoperable and decentralized Electronic Identity Management are rapidly increasing, especially since their contribution towards interoperability across the entire "electronic" public sector, effective information sharing and simplified access to electronic services, is unquestioned. This paper presents an efficient and user-centric method for storing multiple users' identifiers in X.509 digital certificates while preserving their confidentiality, allowing for interoperable user identification in environments where users cannot be identified by an all embracing unique identifier.
