SafeMessage™ provides total privacy by preventing the duplication of its encrypted messages. The sender can set controls over whether the recipient can copy, forward, save or print the message.
When you send an e-mail, every message is stored and forwarded between up to 4 external servers between you and the recipient, as well as your internal e-mail server. This allows your e-mails to be viewed by anyone at any time.
With SafeMessage, all messages are sent directly to the SafeMessage server and the recipient collects them from there.
All messages are encrypted for the intended recipient and further encrypted for the SafeMessage server. In this way the SafeMessage server can decrypt the header element of the message and thereby notify the recipient of the message waiting.
Since the body text and attachments of the message are encrypted solely for the recipient, messages stored at the server cannot be accessed by any one other than the intended recipient.
