Message originator token verification

A system, comprising:

• a communication module;
• and
• a processor programmed to:
• validate, on message retrieval by a message recipient, a digital signature of a message originator of a message as a first-tier validation of the message;
• extract, in response to a successful first-tier validation of the digital signature of the message originator, a transaction token and a message originator identifier from a message payload of the message;
• initiate, as a second-tier validation of the message with a verification service within a secure messaging environment of the message originator, communication via the communication module with the verification service within the secure messaging environment of the message originator using the extracted transaction token and the extracted message originator identifier to confirm whether the secure messaging environment of the message originator generated the transaction token and inserted the transaction token into the message payload;
• and
• determine results of the second-tier validation of the message with the verification service within the secure messaging environment of the message originator.

A computer program product comprising a computer readable storage medium including computer readable program code, where the computer readable program code when executed on a computer causes the computer to:

• validate, on message retrieval by a message recipient, a digital signature of a message originator of a message as a first-tier validation of the message;
• extract, in response to a successful first-tier validation of the digital signature of the message originator, a transaction token and a message originator identifier from a message payload of the message;
• initiate, as a second-tier validation of the message with a verification service within a secure messaging environment of the message originator, communication with the verification service within the secure messaging environment of the message originator using the extracted transaction token and the extracted message originator identifier to confirm whether the secure messaging environment of the message originator generated the transaction token and inserted the transaction token into the message payload;
• and
• determine results of the second-tier validation of the message with the verification service within the secure messaging environment of the message originator.
