Multi-light spectrum palm print identity authentication method and its special-purpose collection instrument

Abstract

The invention relates to a multi-spectrum palm print ID certification method and special-purpose acquisition recorder; the multi-spectrum palm print image acquisition recorder comprises a digital video camera, a multi-spectrum light source, a light source controller, a communication interface, a computer, an instrument bracket with a base, an instrument housing and a palm placement plane, wherein, the digital video camera and the multi-spectrum light source are vertically mounted on the instrument bracket; the instrument housing is fixed outside the instrument bracket and the palm placement plane, so as to form a camera obscura; the light source controller is arranged on the interior side of the instrument housing; the digital video camera and the light source controller are connected with the computer through the communication interface; the invented instrument can acquire high-quality multi-spectrum palm print images, and has the advantages of real-time acquisition and free switch of light sources, so as to meet the requirements for online identification. The acquisition recorder and identification method provided by the invention can well improve universality and stability, as well as anti-fake property and identification performances of traditional palm print and vein identification systems.

Description

(1) Technical field [0001] The invention belongs to the technical field of optical instruments and biological identification, and in particular relates to a palmprint collection and authentication technology. (2) Background technology [0002] With the rapid development of technologies such as photoelectricity, microcomputer, image processing and pattern recognition, a brand-new human biometric identification technology has emerged, which is a high-tech identification technology that relies on human biological characteristics to identify people. [0003] Human biometrics currently mainly use fingerprints, palm prints, iris, voice, handwriting, face and DNA of the human body. Due to the uniqueness and stability inherent in the human body, these features cannot be copied, stolen or forgotten. Therefore, using these unique physiological characteristics of the human body can accurately identify each person's identity. In recent years, human biometric identification technologie...

Problems solved by technology

[0006] However, the palm veins are often interfered by the palm lines, especially the main lines; and some people have thicker hand skins, which makes it difficult to capture clear images; the palm veins are also easily scaled by temperature fluctuations, which affects the image quality

However, palmprints under a single wavelength or white light are easy to be forged by criminals who obtain palmprints, and there are certain security risks.
