Biometric identification chip, system and method

Abstract

The invention provides a biometric identification chip, a system and a method. The biometric identification chip comprises an image preprocessing unit, a biometric identification unit and a determination unit. The image preprocessing unit is used for extracting linear features and denoising points of the acquired biological image signal to obtain a biological feature signal. The biometric recognition unit is configured to acquire biometric coding information of the biometric signal. The judging unit is configured to match the biometric encoding information with the biometric data stored in advance to obtain a biometric recognition result. The invention integrates the image processing and the biometric identification processing into one chip, Embedded biometric chips can be applied to biometric devices or / and biometric systems, thus providing biometric solutions for different application systems, solving the problem of biometric promotion and application constraints, and promoting the rapid acceptance of biometric services such as security and convenience in the market.

Description

technical field [0001] The present invention relates to the field of biometric identification, and more specifically, to a biometric identification chip, system and method. Background technique [0002] At present, in the field of biometrics, software and hardware are constantly developing. Usually, software manufacturers focus on biometric algorithms and develop biometric algorithms based on biometric hardware developed by hardware manufacturers. This is important for the promotion and application of biometrics. There is a problem of constraints. At the same time, software manufacturers do not have a carrier to store biometric algorithms, which can easily make it difficult for software manufacturers to effectively control the intellectual property rights of biometric algorithms. In addition, for the hardware manufacturers of biometric hardware, most of them still focus on the field of image acquisition and image processing, and are relatively deficient in biometrics. This ...

This is important for the promotion and application of biometrics. There is a problem of constraints

At the same time, software manufacturers do not have a carrier to store biometric algorithms, which can easily make it difficult for software manufacturers to effectively control the intellectual property rights of biometric algorithms

In addition, for the hardware manufacturers of biometric hardware, most of them still focus on the field of image acquisition and image processing, and are relatively deficient in biometrics, which leads to poor biometric experience and many difficulties in the promotion and application of biometrics
