Abstract:

Network real-name verification, which is  proposed to solve the problems caused by network anonymity, is criticized for information disclosure. The root cause of the disclosure is that realname authentication relies on personal real-name information. We propose a social-authentication-based network identity model, which relies on social relations, so that it can build an identity to monitor the network while avoiding information leaks. Our model selects root nodes according to a certain strategy, and then implements social authentication by vouching, and finally builds a unique network identity SANI for each node without relying on real-name information. The SNAI identity contains the information of how a node is socially authenticated, and has the ability to authenticate and trace real world identity.
