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 ...

Abstract

The invention discloses a method for confidential data encryption based on biological information authorization and relates to the field of safe data access. According to the invention, biological information data is collected; the biological information data is treated by characteristics vector hash processing; TPM is used to generate a pair of asymmetric secrete keys; hashed biological information is added to a private key for authorization; a public key is used; and TSS is used to encrypt the confidential data into a ciphertext. According to the invention, reliability of a TPM hardware chip and counterfeit resistance of the biological information are combined, so the confidential data becomes safer.

Description

technical field [0001] The invention discloses a method for encrypting confidential data, which relates to the field of safe access to data, in particular to a method for encrypting confidential data based on authorization of biological information. Background technique [0002] Confidential data is information that is not to be disclosed. It generally refers to commercial secrets, research results of national scientific research institutions, central data of biological research institutions, etc. Once confidential data is leaked, it often causes irreparable losses. Therefore, access to confidential data usually enables individual users or user groups to obtain data authorization, and then read or use the data. [0003] Biometrics technology is closely combined with high-tech means such as computer and optics, acoustics, biosensors and biostatistics principles, and uses the inherent physiological characteristics of the human body, such as fingerprints, face images, irises, ...
