If 3) compared successfully, A identity information can confirm that.
If 4) repeatedly compare unsuccessful, it not can determine that A true identity or A sign state may not be normal
State.
5) it is correspondence binary data by the file translations for needing to upload.
6) the corresponding binary data of voice print database binary data corresponding with file is carried out to the XOR of step-by-step successively
Computing, or other logical operation, but the logical operation that uses of encryption with the logical operation of decryption use should be it is corresponding,
Namely use same logical operation.
7) so file has obtained a vocal print encryption and has formd encryption file, stamps trusted timestamp.
8) user A uploads file data to file server, and the user name and credible validity period that will download this segment data
Upload on voice print database processing server.
9) user B downloads to the file data of user A uploads on file server.
10) user B is producing voice print database by application on voiceprint recognition equipment, and recognizes oneself in voice print database processing server
Identity information.
11) user B file data is downloaded to, XOR (secondary encryption) is carried out by user B voice print database again,
And trusted timestamp is stamped, finally upload to voice print database processing server.
12) on voice print database processing server, search user A trust region search whether there is user B, if depositing
, then user A and user B trusted timestamp is carried out to the computing of absolute difference, if in credible validity period, by user B
The file data of upload binary data corresponding with user A voice print database carries out XOR (once decrypting).
