Embodiment Construction
[0026] The present invention provides a confidential data encryption method based on biological information authorization:
[0027] Collect biological information data, and perform feature vector hashing processing on the biological information data,
[0028] TPM is used to generate a pair of asymmetric keys, the private key is added with hashed biological information for authorization, and the public key is used to encrypt the confidential data into ciphertext through TSS.
[0029] At the same time, the present invention also provides a confidential data encryption system based on biometric information authorization, including an acquisition unit, a data processing unit, and a data encryption unit,
[0030] Wherein the collection unit collects biological information data, and the data processing unit performs feature vector hashing processing on the biological information data collected by the collection unit,
[0031] The data encryption unit uses TPM to generate a pair of ...
