Embodiment Construction

[0017] The embedded fingerprint identification module is composed of fingerprint scanning device, DSP processor, FLASH chip and so on. see figure 1 . In the figure, the fingerprint scanning device is responsible for collecting live fingerprint images, and transmits the collected fingerprint images to the DSP high-speed processor (hereinafter referred to as DSP).

[0018] In the fingerprint recording state, DSP uses the fingerprint image processing algorithm to convert the fingerprint image into binary fingerprint template data (less than 64 bytes), and then stores the fingerprint template data in FLASH RAM as the fingerprint comparison Raw data.

[0019] In the state of fingerprint comparison (identity identification), DSP compares the live fingerprint image collected by the fingerprint scanning device with the fingerprint image processing algorithm and each fingerprint template data stored in FLASH RAM one by one, and outputs the comparison For the result - through display...

Abstract

The embedded fingerprint distinguishing module consists of fingerprint scanning device, DSP processor, Flash chip, etc. The present invention features that the embedded fingerprint distinguishing module is small module designed by adopting excellent fingerprint image distinguishing processing algorithm and advanced system level optimizing design theory as well as DSP chip. The present invention has the features of small size, light weight, independent operation, simple embedding and connection, high reliability and high performance/cost ratio. The present invention may be used widely in computer, network, ID, etc.

Description

【Technical field】 [0001] The invention belongs to the field of electronic information and is used for user identification and access control products, in particular to an embedded fingerprint identification module. 【Background technique】 [0002] With the rapid development of informatization and networking, security issues in the social, political, economic, military, and cultural fields have become increasingly prominent, such as information theft, network hacking, financial card fraud, password theft, file leakage, and insurance payment Counterfeiting, loss of guns, preparation of warehouse and home keys, etc., the cunning and superb methods of criminals and hostile forces are amazing. The frequent information crimes and sabotages every year cause hundreds of millions of national and personal property losses, and even seriously threaten national security. While the information superhighway provides convenience for the society, it also provides an opportunity for the sabot...
