Web identity and resolution identifies, authenticates, and locates users on the Web. It's a critical aspect of Web Real-Time Communications (WebRTC), a joint W3C and IETF effort to develop standards for secure real-time communication over the Web. Although WebRTC proposes a security architecture to integrate with federated Web identity systems, the architecture isn't compatible with identity protocols that don't satisfy WebRTC requirements. To fill the gap, the authors describe two alternative architectures to adapt incompatible identity protocols to the WebRTC security architecture. They also describe a Web-of-trust model to address hierarchical identity systems' limitations, and a mirror-presence system to locate users on the Web in real time while they are moving between websites.
