A method for confidential electronic communication between a sender workstation and a receiver workstation is provided, whereby privacy is guaranteed for the electronic communications transmitted over the public Internet. The method of confidential communication is equipped with message tracking and message receipt verification. The system for implementing the method includes a sender server that creates a session content encryption key along with a message envelope that includes a content encryption key encrypted message and a confidential mail token. The content encryption key is stored securely inside the sender organization's system which transmits the message envelope to an intended recipient. The intended recipient processes the message envelope in order to generate a message receipt verification, which is transmitted to the sender. The message receipt verification is processed by the sender server to verify that the message envelope reached the intended recipient. The message receipt verification, which is comprised of the confidential mail token and unique verification data generated by the intended recipient allows the sender server to verify that the message envelope reached the intended receiver and that the message envelope identified as received is authentic. Following verification that the message transmitted by the sender reached the intended receiver and is authorized, the sender transmits the content encryption key to the intended receiver.
