Chip integrating with fingerprint interface, fingerprint algorithm, security algorithms and correlated accelerators

Abstract

The invention discloses a chip integrating with a fingerprint interface, a fingerprint algorithm, security algorithms and correlated accelerators. The chip comprises a fingerprint module, a storage module, a security module and a communication interface, the fingerprint module comprises a sensor interface and a fingerprint algorithm accelerator and is internally cured with the fingerprint algorithm, and the sensor interface is used for attaching various fingerprint sensors known on the market. The security module comprises the security algorithms and a hardware accelerator used for optimization of various security algorithms. The storage module comprises a Ram (random access memory) and a Flash. The chip has the advantages that a general application is physically isolated from data of security and fingerprint programs, exposure of security and fingerprint data and codes is completely eradicated, and attacks launched from the general application are completely prevented; by random combination with a general and universal chip of a mobile terminal, fingerprint authentication and security application are realized; the problem about authentication relation between a digital certificate and human is solved, and privacy protection is realized in the true sense.

Description

Technical field [0001] The invention relates to the field of integrated fingerprint and security chip design, more specifically, it relates to a chip integrating fingerprint interface, fingerprint algorithm and security algorithm and related accelerators. Background technique [0002] With the development of mobile information technology, smart mobile terminals with rich application functions are increasingly becoming the most widely used data processing terminals. At the same time, more and more personal security information such as transaction passwords, fingerprint information, personal data, etc. The frequent use of mobile terminals without professional encryption protection greatly increases the risk of user information leakage, and also brings hidden dangers to the information security of bank transactions and personal data. [0003] Fingerprints, because of their lifetime invariance, uniqueness and convenience, have almost become synonymous with biometric identification. It...
