when the decryption value based on the public key is consistent with the private key encryption value in the MR chip, the encrypted color data stream is decrypted successfully, and the success of face authentication is confirmed;
and when the public key decryption value is inconsistent with the private key encryption value in the MR chip, the encrypted color data stream is failed to be decrypted, and the failure of face authentication is confirmed.
5. The method of claim 1, further comprising:
and the MR chip signs the encrypted color data stream to obtain the encrypted and signed color data stream.
6. A face authentication system is characterized by comprising an image acquisition module, an MR chip, a host and a remote server;
the image acquisition module is used for acquiring a color data stream and a depth data stream, wherein the color data stream at least comprises face image information;
the MR chip is used for encrypting the color data stream to obtain an encrypted color data stream, processing the depth data stream to obtain depth data information, and sending the depth data information and the encrypted color data stream to the host, wherein the depth data stream is used for determining that an object acquired by the image acquisition module is a person;
the host is used for selecting face image information meeting preset requirements from the face image information for transparent transmission processing based on the encrypted color data stream and the encrypted depth data stream, generating face authentication application information, and sending the face authentication application information and the encrypted color data stream to the remote server;
and the remote server is used for decrypting the encrypted color data stream based on the face authentication application information, and if the decryption is successful, the face authentication is confirmed to be successful.
7. The system of claim 6, wherein the image acquisition module comprises an infrared module and a color module;
the infrared module is used for collecting a depth data stream;
and the color module is used for collecting color data streams.
8. The system of claim 6, wherein the host is specifically configured to:
grading the face image information based on an image grading mechanism, and if the face image information meets the image information standard of the image grading mechanism, selecting the face image information meeting the image information standard of the image grading mechanism to perform transparent transmission processing; and if the face image information does not accord with the image information standard of the image scoring mechanism, stopping executing the face image information scoring operation.
9. The system of claim 6, wherein the remote server is specifically configured to:
based on the face authentication application information, carrying out public key decryption on the encrypted color data stream and the signed color data stream to obtain a public key decryption value; when the public key decryption value is consistent with the private key encryption value in the MR chip, the encrypted color data stream and the signed color data stream are decrypted successfully; and when the public key decryption value is inconsistent with the private key encryption value in the MR chip, the encrypted color data stream is failed to be decrypted, and the failure of face authentication is confirmed.
10. The system according to claim 6, wherein the MR chip is further configured to:
and signing the encrypted color data stream to obtain the encrypted and signed color data stream.
