Fingerprint design

Foreword

Fingerprint recognition, as the easiest way to biometric identification, has always been the first choice for identity and identity authorization; in China, fingerprints can be traced back to thousands of years ago in documents and contracts; with modern fingerprints The development of learning, the lifetime immutability, uniqueness and convenience of fingerprints also make fingerprint identification widely used in current payment, security , identification and other occasions.

At present, with the improvement of the awareness of smart devices and the need for secure communication of smart devices, fingerprint recognition functions are being integrated and recognized by more and more products. So how do you integrate this fingerprinting function to meet the needs of different product types?

Fingerprint scheme

In order to meet the fingerprint needs of different product functions in the Internet of Things market, Runxin Technology divides the fingerprint scheme design into a conventional fingerprint scheme, a smart life fingerprint scheme, and a financial security fingerprint scheme.

·Regular plan

The conventional scheme is mainly used for the simple upgrade of the existing door locks. The general MCU integrates the fingerprint sensor to design, including the home, rental and other markets, requiring fingerprint identification to meet the basic specifications of the industry, such as identification time, rejection rate, and error. The recognition rate, etc. can have a better customer experience, and the parameters such as the pixel, resolution, and capacity of the fingerprint are generally required.

The conventional solution Runxin Technology uses the NXP ultra-low-power LPC54 series MCU as the main control, and the fingerprint sensor chip of Huiding Technology forms the conventional fingerprint scheme module FTGAT00xx.

指纹方案的设计

This program has a long battery life and high cost performance. It can be used as an existing fingerprint function for the door lock with a cartoon with a screen. It can also directly replace the existing door lock overall design, saving the original MCU and enhancing the main control. Processing capacity, LPC54 series MCU up to 180Mhz working frequency, with LCD / I2C / USB peripheral interfaces and mature driver solutions, can greatly save the customer project development cycle while ensuring stable performance.

· Intelligent solution

With the popularization of terminal intelligence, a series of smart living ecosystems such as smart cities, smart communities and smart homes have gradually formed, and intelligent interconnection and intelligent interaction have become the inevitable elements of consumption upgrading. The intelligent solution is a fingerprint module solution based on interconnection and mutual control.

Runxin Technology's intelligent solution adopts Qualcomm's high-end low-power IoT third-generation single-chip QCA402X wireless platform chip, which integrates the FTGAQ000xx of the IoT intelligent fingerprint identification program module formed by the high-security fingerprint chip of Huiding Technology.

指纹方案的设计

This solution can support WIFI/BLE/Zigbee/Thread multiple wireless protocols, WIFI can support 2G and 5G working frequency bands, BLE supports V5.0 and SIG Mesh, and Zigbee V3.0 and Thread V1.1 are optional. The platform supports system security startup and command security execution and network authentication mechanism to ensure local and remote attacks and interception to the greatest extent. With the high-precision fingerprint sensor supporting live detection, it can provide very reliable fingerprint recognition for smart living home. Module.

· Financial plan

The development of blockchain technology began with the famous bitcoin application. So far, the digital finance based on blockchain technology has developed rapidly, how can we better manage the virtual currency wealth account, which is currently the total multi-block Chain trading platform vendors are in urgent need of solving problems. The financial solution is precisely the fingerprint module solution to meet such financial security needs.

Runxin Technology Financial Solution adopts NXP financial encryption level MCU, integrated with the latest generation of fingerprint sensor and algorithm fingerprint module FTGAK0001.

指纹方案的设计

This solution features advanced security features including the creation of an active tamper-resistant grid to prevent peripheral tampering, boot ROM support for encrypted firmware updates, dynamic AES decryption and execution from external serial flash, AES acceleration with sideband attack protection And the hardware support of public key encryption, etc., provides reliable financial level protection for applications such as payment and authentication. At the same time, it cooperates with the latest generation of fingerprint sensing with high-precision fingerprint algorithm to provide effective and reliable fingerprint for financial payment. Identify the module.

Conclusion

Runxin Technology has long been committed to providing better, better and smarter IoT solutions for smart life, including platform, communication, security, algorithm and linkage. We welcome everyone to communicate.
