Digital Seal Timestamps

The Digital Seal® email authentication service provides the recipient with proof of original time of transmission of an email.

Standard email is easily edited, times associated with delivery can be manipulated, and sender addresses may be easily spoofed. An email sent as a Registered Email™ message with a Digital Seal® mark not only returns a Registered Receipt™ email proof of delivery record for the sender, but also provides the recipient a simple way to verify original content, and original timestamp of transmission. 

The Digital Seal® technology reconstructs the electronic originals on demand, for any recipient or future recipient if the email has 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 is be forwarded, scanned, or saved.
