Cross-domain identity and discovery framework for web calling services

Cross-domain identity management remains a major challenge for potential WebRTC adopters. In order to provide a global web-based communication system, it is critical to locate the destination called party, map the identity to the user device, and provide mutual authentication for both caller and called party. In this paper, we present a novel identity management and user discovery framework that enables callers to search and locate users across service domains. The identity management is decoupled from the used calling service, allowing users to manage their profiles and credentials independently of the applications. The framework is designed to preserve privacy and exploit web technology to gain trust and contact list management. * Ibrahim Tariq Javed [email protected] Rebecca Copeland [email protected] Noel Crespi [email protected] Marc Emmelmann [email protected] Ancuta Corici [email protected] Ahmed Bouabdallah [email protected] Tuo Zhang [email protected] Saad El Jaouhari [email protected] Felix Beierle [email protected] Sebastian Göndör [email protected] Axel Küpper [email protected] Kevin Corre [email protected] Jean-Michel Crom [email protected] Ingo Friese [email protected] Ana Caldeira [email protected] Gil Dias [email protected] Nuno Santos [email protected] Ricardo Chaves [email protected] Ricardo Lopes Pereira [email protected] 1 Institut Mines-Telecom, Telecom Sud-Paris, Evry, Paris, France 2 NGNI, Fraunhofer FOKUS, Berlin, Germany 3 Department SRCD, IMTAtlantique, Cesson-Sévigné, France 4 Technische Universität Berlin, Telekom Innovation Laboratories, Berlin, Germany 5 Orange Labs Products & Services, Cesson-Sévigné, France 6 Telekom Innovation Laboratories, Berlin, Germany 7 INESC-ID, IST, Universidade de Lisboa, Lisbon, Portugal Ann.
