PHONE KEY AUTHENTICATION

Abstract

A phone key registration process between a user and an institution directed to establishing an audible sound or a collection of audible sounds recognizable to a user and stored with the institution. Subsequent to establishing the phone key, when the institution calls the user, the registered phone key may be played back to the user allowing the user to authenticate that the calling party is, indeed, the institution which the user registered the phone key with. Such a process may prevent an unauthorized party without knowledge of the phone key to call a user acting as the institution to illegally obtain private or sensitive information.
