Abstract
Methods and systems described herein are directed to verifying a caller's identity during a phone call by exchanging sub-audible tones between two parties to a phone call. A code, password, or other message can be embedded within telephone audio signals as sub-audible tones, which can be used to facilitate a verification process. The combined audio signal that includes sub-audible tones can be analyzed by a receiving device to extract an embedded code or message. Aspects of cryptographic schemes can be implemented using sub-audible tones—such as time-based one-time passwords (TOTP) and handshakes—which verify the identity of a party to a call. Based on the outcome of the verification process, the user can be notified whether verification was successful.
