Identity information identification method and identity information identification system

Abstract

The invention provides an identity information identification method and an identity information identification system. The method comprises the following steps: supporting the palm: placing the palm to be identified on a palm-supporting device; obtaining hand back vein information: obtaining a palm vein image of the palm to be identified on the palm-supporting device; obtaining palm print information: obtaining a palm print image of the palm to be identified on the palm-supporting device by a palm print information obtaining device aligned to the other side of the palm-supporting device; processing and identifying an identity: respectively processing and obtaining corresponding hand back vein texture information and palm print texture information; constructing an identity characteristic vector according to the hand back vein texture information and the palm print texture information; and comparing the identity characteristic vector with registered sample characteristic vectors preliminarily stored in an identity characteristic vector library to judge the identity of a user.

Description

technical field [0001] The invention relates to an identity information identification method and system thereof, in particular to a method and system thereof for identity information identification by collecting veins and palm prints of a living body. Background technique [0002] Now, the research and product development of human body biometric identification technology has been valued by many scientific research institutes and enterprises. Fingerprint recognition with the No. 200810217350.8, finger vein recognition with the patent application No. 200910013851.9, palmprint recognition and palm vein recognition with the patent application No. 200710144946.4, etc. Among them, the recognition technology and products based on vein features attract the most attention. Compared with other biological features such as faces and fingerprints, vein features have the following advantages: 1) Vein is a living feature, which is difficult to forge; 2) Vein is under the skin and has goo...

Problems solved by technology

[0003] However, the features used in the existing vein recognition technology, such as the finger veins with the patent application number 200910013851.9 and the palm veins with the patent application number 200710144946.4, have common disadvantages, that is, both of these two veins are deep under the skin, and the The depth distribution of the vein is not uniform, the contrast of the vein image acquired by the existing near-infrared imaging equipment is low, the degree of light and shade changes at the intersection of the edge of the vein and the background is low, and the width and distribution of the vein are not clear, which makes the vein extraction algorithm difficult. As a result, the finger veins and palm veins extracted from the image are not accurate enough and blurred, seriously affecting the accuracy of recognition and greatly limiting the imaging conditions, which significantly reduces the applicability of the product in the market

In addition, accidental injury and physiological pathology may cause significant changes in biometric characteristics, causing single-modal authentication systems to often deny legitimate users
