Embodiment Construction
[0137] In the multi-mode biological feature fusion system of the present invention, the fusion module is the key.
[0138] First, the location of the fusion module is in the matching layer. That is to say, the input of the fusion module is the score output by each biometric authentication sub-module after template matching. This is not only different from using the feature vectors output by different biometric authentication systems as input when the feature layer is fused, but also different from using the logic variables output by different biometric authentication systems as input when the decision-making layer is fused.
[0139] Secondly, according to the different requirements of identification and authentication, the fusion module is divided into identification fusion sub-module, authentication fusion sub-module and identification authentication fusion sub-module. The identification fusion sub-module needs to complete the work of judging "who is the user?", that is, it ...
