主 题：Palmprint recognition hetero-associative memory neural network and Siamese network
摘 要：Many types of research focus on utilizing Palmprint recognition in user identification and *** Palmprint is one of biometric authentication(something you are)invariable during a person’s life and needs careful protection during enrollment into different biometric authentication *** and irreversibility are critical requirements for securing the Palmprint template during enrollment and *** paper proposes an innovative HAMTE neural network model that contains Hetero-Associative Memory for Palmprint template translation and projection using matrix multiplication and dot product multiplication.A HAMTE-Siamese network is constructed,which accepts two Palmprint templates and predicts whether these two templates belong to the same user or different *** HAMTE is generated for each user during the enrollment phase,which is responsible for generating a secure template for the enrolled *** proposed network secures the person’s Palmprint template by translating it into an irreversible template(different features space).It can be stored safely in a trusted/untrusted third-party authentication system that protects the original person’s template from being *** results are conducted on the CASIA database,where the proposed network achieved accuracy close to the original accuracy for the unprotected Palmprint *** recognition accuracy deviated by around 3%,and the equal error rate(EER)by approximately 0.02 compared to the original data,with appropriate performance(approximately 13 ms)while preserving the irreversibility property of the secure ***,the brute-force attack has been analyzed under the new Palmprint protection scheme.
