Digital Seal for Content Authentication

The Digital Seal® email authentication service provides the recipient with proof of original message body text and attachments.

The message content of an email received may be easily modified before it reaches its intended recipient. Internet criminals take advantage of a variety of techniques to intercept email and re-transmit with altered content. The most lucrative of these Internet crimes is altering payment details in an email or its attachment to trick the recipient (or a future recipient that the email has been forwarded to) into paying an invoice or sending funds to an impostor bank address. These impostor email attacks come in many forms and are commonly referred to as Business Email Compromise email impostor attacks.  

An email sent as a Registered Email™ message returns a Registered Receipt™ email proof of delivery record for the sender, but a Registered Email message alone does not provide the recipient a means of authenticating the original message content received. And, future recipients (after an email has been forwarded) have even less assurance or ability to verify email content integrity. 

Adding the Digital Seal® feature to a sent Registered Email™ message provides the recipient a simple way to verify not only original sent content (including attachments), but also authentic author/sender (and original timestamps of transmission). 

The Digital Seal® technology reconstructs the electronic originals on-demand, for any recipient of future recipient after the email may have been forwarded to others or saved in a storage drive. 

This Digital Seal® serves as the ultimate forensic evidence of the email transmission, timestamp, and authorship.  

A Certified Email™ transmission is the combination of the Registered Email™ delivery proof plus the Digital Seal® sender authentication technologies. 

Unlike Digital Signatures on email, which are not recognized by most browser-based email programs and which lose their integrity if an email is forwarded or modified by anti-virus filters, the Digital Seal® technology applies a durable authentication mechanism that stays with the email regardless of how many times it may be forwarded, scanned, or saved.
