The present disclosure describes systems and methods for managing network traffic using biometrics. A server may store a first value N, a primitive root modulo N, and a plurality of verification codes generated using the primitive root modulo N to the power of a hash function result of a respective portion of a first biometric template acquired from the user during enrollment. The sever may receive a request to connect to the server, from a client operated by the user. The client may use a first offset identifier from the server to identify a first portion of a second biometric template acquired from the user, and generate a first value corresponding to a common exponentiation function. The server may generate a second value corresponding to the common exponentiation function. The server may determine that the user is authenticated if the first value from the client matches the second value.
