Post-quantum biometric authentication based on homomorphic encryption and classic McEliece
(MDPI, 2023-01)
Homomorphic encryption is a powerful mechanism that allows sensitive data, such as biometric data, to be compared in a protected way, revealing only the comparison result when the private key is known. This is very useful ...
