Identity recognition method and device capable of simultaneously capturing human pulse and vein images

Abstract

The invention provides an identity recognition device capable of simultaneously capturing human pulse and vein images. The identity recognition device comprises a palm detection table, wherein the palm detection table includes a base and a top connected to the base; a first light source is arranged in the base of the palm detection table and can penetrate out of the upper surface of the base of the palm detection table; a second light source and an image signal acquisition unit are respectively arranged below the top of the palm detection table; and the image signal acquisition unit is used for acquiring transmission light and reflection light formed by the first light source and the second light source through the detected hand and is connected with the signal processing unit. Meanwhile,the invention provides an identity recognition method implemented by adopting the identity recognition device. According to the identity recognition device, the potential safety hazard that vein identification is carried out by using vein photos or 3D molds to forge hand veins of a real person is eliminated, and the robustness of the system is improved; the defect of step-by-step operation in a traditional method is overcome, and the efficiency of the system is improved; and the price is low; popularization and application are easy.

Description

technical field [0001] The invention belongs to the technical field of identification, and in particular relates to an identification method and device capable of simultaneously capturing human pulse and hand vein images. Background technique [0002] With the rapid development of information technology, the security of personal information is becoming more and more important. Traditional identification methods such as magnetic cards, ID cards, etc. can no longer ensure the uniqueness and authenticity of identity due to the fact that the identification information is easily forged or lost, and cannot meet the needs of the market. As an emerging identification technology, biometric identification technology is more and more favored by the public because of its inherent uniqueness and stability. The most commonly used biometrics include fingerprints, faces, irises, and veins. [0003] Fingerprint identification is the most widely used biometric identification technology. Due...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the existing problems of the living body detection technology in vein recognition are: 1. The simple vein recognition detection method cannot solve the problem of camouflage recognition; 2. The vein recognition of adding living body information detection is carried out in two steps, and the efficiency is not high; 3. Existing detection devices are expensive, difficult to operate, and difficult to promote
