Abstract

The embodiment of the invention provides an identity authentication method and device based on finger vein recognition, and relates to the field of artificial intelligence. The method comprises the steps of obtaining a finger vein image of a target user; filtering the finger vein image of the target user by adopting the target convolution kernel; extracting an ROI region of the filtered finger vein image of the target user to obtain a target region image; extracting a finger vein feature vector from the target area image to obtain a target finger vein feature vector; obtaining all finger veinfeature vectors stored in a preset database; respectively calculating the similarity between the target finger vein feature vector and all finger vein feature vectors stored in a preset database to obtain a plurality of similarities; and if at least one similarity in the plurality of similarities is greater than or equal to a preset similarity threshold, determining that the identity verificationof the target user succeeds. According to the technical scheme provided by the embodiment of the invention, the problem of low identity verification accuracy based on the finger vein image can be solved.

Description

【Technical field】 [0001] The invention relates to the field of artificial intelligence, in particular to an identity verification method and device based on finger vein recognition. 【Background technique】 [0002] Finger vein recognition technology uses the texture of finger vein blood vessels for identity verification, which is harmless to the human body and has the characteristics of being difficult to be stolen or forged. The identification technology can be widely used in access control systems in banking, finance, government, education and other fields. [0003] At present, the problem of finger vein recognition technology is: because the finger veins exist under the skin, the finger vein image matching process is easily disturbed by the skin texture, resulting in low accuracy of finger vein image matching, which in turn leads to identity verification based on finger vein images. Accuracy is low. 【Content of invention】 [0004] In view of this, an embodiment of the ...
