Abstract

A method and apparatus for securely communicating data employs a third-party to facilitate decryption by the recipient. It is necessary for the recipient to interact with the third-party to decrypt received encrypted data. The third-party is unable to decrypt or read the encrypted data and records whether the recipient requested a decryption key generated by the third-party. The third party logs the request from the second party for the decryption key. The originator may then obtain the delivery status of the data from the third party to facilitate proof of submission, proof of delivery, or any other suitable information.
