ABSTRACT:
A system and method for verifying messages. The method may include the steps of receiving an inbound message and characterizing the inbound message by analyzing a latent cryptographic identifier in the inbound message. The identifier is generated by a recognized message system, which may be the receiving system itself, for an outbound message. Characterizing may involve detecting if the latent cryptographic identifier is present and determining if the cryptographic identifier is valid. The step of determining can be performed using symmetric or asymmetric methods of verifying the authenticity of the message.
