Abstract

According to one aspect of the present disclosure, a method and technique for caller authentication is disclosed. The method includes, responsive to receiving a call from a telephone unit, identifying a received encrypted identification object having information associated with an identity of a caller placing the call. A telephone number corresponding to the caller is identified and a decryption key associated with the call is generated by combining the telephone number with a decryption code. The identification object is decrypted using the generated decryption key and an identity of the caller placing the call from the second telephone unit is verified based on the decrypted identification object.
