Finger print biological identifying engine system and its identifying method based on credible platform module

Abstract

This invention relates to a fingerprint biology identifying engine system based on a trustable platform module and a method, in which, the TPM chip in the system has a functional module and a chip operation system, a fingerprint sensor, a fingerprint collection and a process module loaded by the computer mainboard, a nonvolatile memory, a fingerprint comparing module in the TPM chip of the trustable platform module, in which, the sensor is connected with the non-volatile memory by the collection module, a process module and the fingerprint comparison module. Said method includes collecting the original image information of the fingerprint, picking up its character information and generating an identification code, judging if the initial fingerprint has registered then to store the identification code in the non-volatile memory of the TPM chip or pick up the identification code stored in the TPM chip to be compared.

Description

technical field [0001] The invention relates to the technical field of computer biometric identification, in particular to the technical field of computer fingerprint biometric identification, in particular to a fingerprint biometric identification engine system based on a trusted platform module and an identification method thereof. Background technique [0002] In the middle of the 19th century, humans began to study fingerprints in a scientific sense, and came to two important conclusions: no two fingerprints have the same shape of the lines; the shape of the fingerprint lines remains unchanged throughout life. Fingerprint identification technology is currently internationally recognized as the most widely used, cheapest, and most easy-to-use biometric authentication technology. Compared with other identity authentication technologies, automatic fingerprint identification has many unique information security advantages as follows: [0003] (1) The fingerprint of each pers...

Problems solved by technology

[0017] At the same time, in order to achieve a deeper level of computer security, we must start from the TPM. At present, for the TPM chip, it only stays in the secure encrypted storage of fingerprint data, that is, the fingerprint feature information is stored in the TPM or encrypted in the TPM. Externally, this only manages and stores fingerprint data information as important information, and does not really play the significance of fingerprint identification itself
