Abstract

The invention provides an identity control method based on TPM and fingerprint identification that includes steps: A1, presetting the fingerprint characteristic information module, the module is protected by the TPM; A2, the fingerprint collecting module collects the image information of present user's fingerprint, and the information is transmitted to the fingerprint extracting module; A3, the fingerprint extracting module extracts and calculates the characteristic of fingerprint, and the results is sent to the TMP chip; A4, The fingerprint comparison module of the TMP chip compares with the fingerprint characteristic data extracted this time according to the fingerprint characteristic module to identify the user's identity; A5, the TPM chip judges that the user has the authority to operate the computer according to the comparing result and to execute the step A6, otherwise execute the step A7; A6, the TPM chip works normally and executes the operation of user's requirement; A7, the TPM chip is in inactive state and rejects the operation of user's requirement, and return the error information for upper layer.

Description

technical field

[0001] The invention relates to the field of computer information security, in particular to a method for computer user identification and authority control using fingerprint biometric technology and trusted platform module chip technology. Background technique

[0002] With the advent of the Internet age, information security has become a common concern of computer users. People have higher and higher requirements for computer security. The application of fingerprint recognition technology in computer user identification and operation access authority confirmation is also increasing. widely.

[0003] Before the Trusted Platform Module (TPM, Trusted Platform Module) chip appeared, fingerprint recognition technology mainly adopted two implementation modes in the application of computer user identity authentication:

[0004] Mode 1: Fingerprint recognition and comparison algorithms are realized entirely through computer software. This mode cannot realize user...
