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

The invention discloses a multimode biological identifying device and a method thereof. The multimode biological identifying device comprises three basic modes, namely, an infrared spectrum biological identifying technology, a hand biological identifying technology and a fingerprint biological identifying technology, and is characterized in that: by combining the infrared spectrum biological identifying technology, the hand biological identifying technology and the fingerprint biological identifying technology, a multimode comprehensive biological identifying system device is formed. According to the invention, a biological characteristic acquiring system is made by combining a laser technology, an infrared spectrum technology and a data acquiring technology, and the device consists of a biological signal acquiring unit, a signal transmitting and processing unit, a microprocessor unit, a control unit, a display and alarm unit and an interface unit. Due to the adoption of the multimode biological identifying method and the device thereof, the defect of low identifying rate of the conventional single-mode identifying system is overcome, a novel technical support is provided for an attendance system, a gate control system and a safety supervision system, high identifying accuracy is achieved, and the counterfeiting property of the system is ensured.
Description
technical field [0001] The invention belongs to the technical field of biological feature identification, and in particular relates to a multimodal comprehensive biological identification device and a method thereof. Background technique [0002] 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 authentica...
