Due to biological characteristic similarity in image acquisition and physiological complementarity of the face and the ear,a face and ear multimodal fusion template protection method was proposed,in which the face and the ear were combined in the feature level and then a fuzzy vault was utilized to protect the fusion feature template. The basic flow of the scheme was divided into 5parts: image preprocessing,Gabor- PCA feature extraction,feature fusion,fusion template encryption,and fusion template decryptio...
