This paper illustrates requirements for network trusted identity management, then studies international strategy on network trusted identity, international standards and behavior-based risk control techniques, summarizes the international situation and tendency on identity management research, and finally proposes three considerations on trusted identity management mechanisms, laws and regulations and new techniques.
