  • Secure electronic document delivery system
    Patent number: 9948627
    Abstract: The secure electronic document delivery system enables a sender to identify file information and recipient information to be sent to a recipient. The system utilizes an authentication system requiring access to two different authentication messages, both access to electronic mail and access to a message sent to the recipient's phone. The two authentication messages are transmitted via two different communication paths thus requiring the recipient to access two different types of communications. Without accessing both messages, the recipient cannot access the document identified by the sender.
