[0037] The present invention will be further described below with reference to the accompanying drawings.
[0038] A method for realizing a finger vein fusion fuzzy vault mainly includes three parts: the first step is to fuse the finger vein skeleton information on the finger vein A and the finger vein B images to obtain the vein skeleton image C, and extract the feature points to obtain a feature information set And extract its characteristic information set. The second step is to use the locking algorithm to bind the key to be protected with the feature set in the first step to generate a finger vein fusion fuzzy vault. The third step is to use the verified query finger veins A' and B' to fuse the finger vein skeleton information to obtain the vein skeleton image C', extract the feature information, and use the unlocking algorithm to extract the key from the finger vein fuzzy vault.
[0039] The described fusion of the finger vein skeleton information on the finger vein A a...
