Abstract: A method of verifiably transmitting an Electronic Package such as an email and associated attachments, from a sender to a recipient through a system that utilizes a certifying authority via a communications network. The certifying authority consists of trained personnel capable of verifying the authenticity and detailed history of the electronic package. The method involves the steps of transmitting an Electronic Package from a sender to the System via the communications network; storing a first set of particulars relating to the Electronic Package on a server operated by the certifying authority for use in subsequent verification of the particulars relating to the Electronic Package; delivering the Electronic Package and generating an encrypted hash value based on selected particulars; creating an Electronic Certificate of Service that allows verification to and proof of particulars and integrity of the original message.
