Abstract: Secure electronic transactions using a trusted intermediary with non-repudiation of receipt and contents of message. A system of, and method for, securely transmitting a package from a sender to a recipient, via an intermediary, are described, as is a novel data arrangement, stored in a computer-readable medium. A sender encrypts the message to form an encrypted inner envelope. A waybill is formed that among other things identifies the recipient as the destination and includes information indicating various levels of services desired, e.g., electronic notarization. The waybill and inner envelope are used to form an encrypted outer envelope that is addressed to a trusted intermediary. The intermediary receives the package and decrypts the outer envelope. It is unable to decrypt the inner envelope, due to the keys employed during encryption. The service information is processed, and the package is used to form a second package addressed to the recipient.
