Identity authentication system with biological characteristic recognition function and authentication method thereof

Abstract

The invention relates to an identity authentication system with biological characteristic recognition function and an authentication method thereof. The system comprises a CPU main control unit (MCU), a system control unit, a hardware encryption and decryption unit, an on-chip memory with MPU protection function, an external communication unit, a man-machine interaction control unit, an external memory control unit, a PKI system and a sensor system, wherein the on-chip memory is used for realizing secure storage and access of such data as personal information, data, procedures, keys, system parameters, etc. The invention has the following beneficial effects: 1. solving the problem of security holes of pins of existing security products, radically solving the problem of authentication of personal identity and having high security; 2. guaranteeing the personal information of the user not to be cracked by logic attacks, side frequency attacks, physical attacks and other means through the hardware; 3. guaranteeing the personal information of the user to be securely stored and not to be cracked by splitting and photographing the chips and other means through the hardware; and 4. effectively avoiding the leak that the transaction information is tampered when the transaction information is sent to the personal identity authentication terminal.

Description

technical field [0001] The invention relates to the fields of information security, mobile payment and biometric identification, in particular to an identity authentication system with a biometric feature identification function and an authentication method thereof. Background technique [0002] As the first gate of information security, user identity authentication is the prerequisite for various security measures to play a role. As the core component of computing infrastructure for all information security applications, PKI products can provide more functions and better services for the safe storage and transmission of personal information. Among them, the electronic visa agency (CA), as the third party of communication, provides trusted authentication services for various services. CA can issue electronic visa certificates to users, and provide users with functions such as member authentication and key management. [0003] At present, identity authentication products fo...

Problems solved by technology

[0007] Patent Application No. CN101561873A and Patent No. CN201349222Y both reveal that the uniqueness of the biological characteristics of the human being is used to enhance the security of the use of the USB Key at the hardware device level and the software level respectively, but it does not fundamentally solve the identity of the device holder. determination of

At the same time, because the method of adding a biometric module is expensive, and it is difficult to upgrade on existing general-purpose devices such as PCs, it is difficult to implement on PDAs and / or mobile phones.

The patent application No. CN 101251878A discloses that by putting personal security information on the hardware SD card, it solves the common problem of PC and mobile devices, and solves the identity confirmation of the hardware device to the bank terminal, but it also cannot fundamentally solve the problem of the device. The holder's identity confirmation to the bank terminal
