The European Telecommunications Standards Institute (ETSI), a nonprofit that produces standards for information and communications technologies, has completed a set of identity management specifications which outline how users can safely gain authorized access to data and services. The free specifications, which are aimed at network operators, internet service providers and systems designers, address access control issues related to third-parties and cloud environments. The specifications were created by ETSI's identity and access management for networks and services group, whose members include Nokia Siemens Networks, Alcatel Lucent, the University of Patras in Greece, and the University of Murcia in Spain.
