C (57) Abstract: A finger vein recognition and anti-counterfeiting integrated method and apparatus, a storage medium, and a device.  
The method comprises: preprocessing a finger vein image; inputting preprocessed finger vein data into a finger vein recognition an
ti-counterfeiting task convolutional neural network model to obtain an anti-counterfeiting task classification probability p and a recog
nition task feature vector v; in a registration mode, when the anti-counterfeiting task classification probability p is less than or equal 
to a probability threshold si, outputting and saving the recognition task feature vector v; and in a recognition mode, by comparing 
the anti-counterfeiting task classification probability p with a probability threshold si and comparing the cosine distance between the 
e recognition task feature vector v and a recognition task feature vector of each registered

sample with a distance threshold S2, outputting the determination result. The method integrates two tasks of finger vein recognition and 
finger vein anti-counterfeiting into a unified algorithm, so that the vein recognition efficiency and the system real-time performance 
are improved while the recognition and anti-counterfeiting precision is ensured.
