Framework of biometric authentication applied in open network
开放网络中的一种生物认证应用框架

A framework of biometric authentication applied in the open network was proposed. In the framework, after identity authentication is carried out with the cooperation of Biometric Process Unit (BPU) distributed at different locations, the instances comprising BPU certificate, BPU function report and result were generated respectively by each BPU and sent to the identity verifier. The verifier retrieved responding authentication policy from Biometric Policy Certificate (BPC) according to the privilege recorded in the user's Attribute Certificate (AC) and checked if these BPUs met the requirements. If so, the verifier accepted this authentication result.
