Abstract

The invention discloses a hand vein recognition method and device for dual living body verification, and relates to the field of identity verification. The method comprises the steps of obtaining physiological parameters of a to-be-verified hand; performing action feature living body verification when the physiological parameters are greater than a first preset threshold value; calculating the palm similarity and the hand back similarity after living body verification succeeds; and if both the palm similarity and the hand back similarity are greater than a second preset threshold, indicating that the hand vein recognition succeeds. According to the invention, dual living body verification is carried out in a manner of combining action characteristics and physiological parameter detection;the palm vein image and the hand back vein image are respectively extracted for vein recognition, the reliability is improved through dual living body verification and dual vein recognition of the palm vein image and the hand back vein image, and the method and device are particularly suitable for occasions with very high reliability requirements.

Description

technical field [0001] The invention relates to the field of identity verification, in particular to a hand vein recognition method and device for dual biometric verification. Background technique [0002] Vein recognition is to obtain images of hand veins through near-infrared cameras, and store the digital images of veins in a computer system to realize feature value storage. During the vein comparison, the vein map is taken in real time, and the features of the digital image are extracted by means of advanced filtering, image binarization and refinement, and the complex matching algorithm is used to compare and match the vein feature values ​​stored in the computer system host. Thereby identifying and confirming the identity of the individual. Veins are located inside the human body and are not affected by the rough skin and the external environment. The use of vein recognition has the advantages of high accuracy, difficulty in replication, safety and convenience. Vein r...
