The invention relates to an anonymous file examination and approval method. The anonymous file examination and approval method is implemented by a
server and a
client, and the method comprises the following steps: a user authenticated by a CA
authentication center and having a
certificate issued by the CA
authentication center submits a to-be-examined and approved file, uploads the file to the
server, selects the number of people requiring examination and approval, and sets an examination and approval sequence; the
client fills examination and approval serial numbers and approver names, sendsthe examination and approval serial numbers and the approver names to the
server, and randomly allocates an ID; the user provides an examination and approval application for the
client, the client queries whether a to-be-examined and approved project exists, meanwhile the server receives a current
client certificate and judges whether the current
client certificate is correct, thereafter the client receives the information and examines and approves the information, after the examination and approval are accomplished, the client selects a blinding factor for an examination and approval result xand the allocated ID for blinding the examination and approval result x to obtain a blinding result e, and performs signature. The identity information of approvers cannot be obtained in the whole process, thus realizing the
anonymity of the result in the examination and approval process, and after all examination and approval is accomplished, the server performs statistics on the stored data andprovides the
final examination and approval result.
