Abstract: In an embodiment of the present disclosure, a biometric identification device comprises a conversion engine configured to receive a key file, receive a biometric file, wherein the biometric file is different from the key file and comprises biometric identification information of a user, convert the key file into a first numeric representation, and convert the biometric file into a second numeric representation. The biometric identification device further comprises a hashing engine configured to create a superimposed numeric representation by performing a convolution operation on the first numeric representation and the second numeric representation, convert the superimposed numeric representation into a hash value, and store the hash value.

Abstract: In an embodiment of the present disclosure, an embodiment includes a user device comprises a conversion engine configured to receive a biometric file comprising biometric identification information of a user and convert the biometric file into a first numeric representation. The user device further comprises a hashing engine configured to create a superimposed numeric representation by performing a convolution operation on the first numeric representation and a second numeric representation, wherein the second numeric representation is based on a key file that is different from the biometric file. The hashing engine is further configured to convert the superimposed numeric representation into a hash value, send, over a network connection, the hash value for authentication, and receive a message indicating whether authentication was successful.
