Intelligent biological recognition method and working flow thereof

Abstract

An intelligent biological recognition method and a working flow thereof comprise the technologies of infrared spectroscopy biological recognition, hand-shaped biological recognition and fingerprint biological recognition. The working flow comprises following steps: first, by means of a computer device, information obtained through spectrum data acquisition, hand-shaped data acquisition and fingerprint data acquisition is input into a microprocessor unit; information fusion is performed to the above data by an intelligent control unit system and then the information is written-in a backstage individual biological feature information database management system, and a fingerprint sensor and a three-dimensional image acquisition device are adopted to develop a miniature and integrated hand-shaped and fingerprint integrated data acquisition system by means of an advanced microprocessor; after the information is input in the computer, matching query is performed to the information in the individual biological feature information database through wireless communication or local area network; protocol interface unit technology is adopted to design a system external interface; display, comparison and information (image and acousto-optic aspect) feedback are performed to the acquired data and alarming is given through display and an alarm unit.

Description

technical field [0001] The invention relates to the technical field of biological feature identification, in particular to an intelligent comprehensive biological identification device and a method thereof. Background technique [0002] Today, with the rapid development of computer technology and new theories in today's information society, modern biometric identification technology has been rapidly developed and applied. On the other hand, the demand for personal identity authentication and management is also growing. Biometric recognition is a technology that uses the unique physiological and behavioral characteristics of the human body for automatic identification, including vein recognition, face recognition, voice recognition, and iris recognition. It has been widely used in salary assessment systems, access control systems, and safety monitoring systems. , Government affairs systems, and all aspects of social life such as digital terminal access, identity authenticatio...

Problems solved by technology

[0003] However, the current research on biometric identification technology generally focuses on the study of single-modal identification systems. Although it has the characteristics of rapid identification, there are also many problems that cannot be overcome only by single-modal identification.

Because when using a single technology and module, it is difficult to achieve effective identification, and its accuracy is not high. For example, human fingerprints can be copied and forged relatively easily, so there is a possibility of using forged fingerprint copies to deceive the fingerprint identification system. sex, unstable
