Method, device and equipment for generating palm vein feature template for resisting similarity attack

The embodiment of the invention provides a palm vein feature template generation method, device and equipment for resisting similarity attacks. The method comprises the following steps: acquiring original palm vein data, and obtaining an initial palm vein feature vector according to the original palm vein data; performing random projection on the initial palm vein feature vector to obtain a randomized palm vein feature vector; performing multi-dimensional spectral hashing on the randomized palm vein feature vector to generate a first palm vein feature template; performing nonlinear transformation on the first palm vein feature template by using a nonlinear activation function to obtain a second palm vein feature template; and performing binary conversion on the second palm vein feature template to obtain a third palm vein feature template. In this way, under the condition that performance loss is kept, similarity attacks can be resisted, and higher safety is achieved; the map segmentation technology is used,
