Abstract: Firstly, this paper proposes a generalized concept of privacy preserving computing from the perspective of technology essence with an open concept, that is, privacy preserving computing can be understood as a computing paradigm that correctly realizes the computing goal under the premise of effectively protecting sensitive information. Then, based on five party architecture model of cyberidentity authentication, aiming at the protection level of sensitive information in the two links of identity issuance and identity authentication, a hierarchical method of privacy preserving computing in cyberidentity authentication is proposed. Finally, the privacy preserving computing level analysis of three kinds of mainstream cyberidentity authentication mechanisms of smart key, static password and biometrics is performanced, and targeted improvement schemes are proposed for nonprivacy preserving computing identity authentication mechanisms that do not meet the requirements of privacy preserving computing level.
