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.
