Encrypted Biometric Registration

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.
