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...

AI Technical Summary

Problems solved by technology

[0011] 1. The security of the final product solution is not high, because security and fingerprint-related applications are at the same level as general applications, and are stored in the same code area and data area. Although sensitive information can be protected by passwords, once unlocked, it will be Vulnerable to any underlying software vulnerabilities, vulnerable to attacks and data leakage;

[0012] 2. Since many professional security algorithms and fingerprint algorithms need hardware implementation, method 1 does not have professional security algorithms, fingerprint algorithms, and required hardware accelerators, which makes the security application and fingerprint application of this method not so fast , excellent and professional;

[0013] 3. There is no dedicated fingerprint sensor interface, and it is more complicated to mount the sensor

[0015] 1. Method 2 is protected by patents through the internal implementation method, and no details are announced. Only the company can develop products, which is not universal and cannot easily use third-party algorithms;

[0016] 2. Due to the overall fusion in the same chip, it will be difficult to upgrade the hardware algorithm, and the product needs to be replaced as a whole when updating, which is not flexible;

[0017] 3. Only a few unique sensors are well supported, and it is inconvenient to connect other sensors

[0018] 4. It cannot be applied to other general-purpose chips. Module customization and design are not the professional scope of product design companies or platform-based application development companies.
