Abstract: Systems and methods for secure communications in a communications network (100), including a server (102) and a client device (104a, 104b), are provided. A method includes transmitting a communications session request from the client device to the server (304), the session request including an in-situ biometric code associated with a biometric sample of a user. The method also includes separately comparing at the server and the client device the in-situ biometric code and an associated canonical biometric code based on comparison criterion (208, 310), the canonical biometric code representing a biometric reference for the user. The method also includes generating an encryption key at the server and at the client device based on the in-situ and canonical biometric codes (218, 314). The method further includes establishing an encrypted communications session between the server and the client device if the in-situ biometric code meets comparison criteria at the server and at client device (220, 316).
