Abstract

An email message generally consists of multiple parts - different representations of the message text and possible some attachments. When one encrypts an email message, sometimes these different parts could have different levels of security. For example, the message text could be "Here are those numbers" and the attachment could contain all the payroll figures for the current quarter. With that in mind, it would be nice to indicate if certain message parts are "For Your Eyes Only." The benefit is that it would prevent the user from sending those message parts from a mobile device or computer in a plain text/weak format (for encrypted attachment viewing) or from forwarding those message parts to someone else. The proposed solution is to add a "For Your Eyes Only" attribute to each message part in an encrypted message. Software that can interpret this attribute will prevent those message parts from leaving the device. So in the example of encrypted attachment viewing, the presence of this attribute will prevent that attachment from being sent off the device to other recipients. In another example, if the user goes to forward/reply to that message, any parts marked as "For Your Eyes Only" will not be included in the forward/reply. That way those message parts never leave the device. Currently, PGP has a way to mark a message so that it can only (in the PGP Application) be viewed with a "secure viewer." The benefit of this viewer is that the font it uses helps make it tempest-resistant (i.e., resistant to reading what's on your monitor using its electromagnetic emissions). The PGP method only deals with how to view certain data on the machine itself. You are still able to forward the data off your machine if you want. Our proposed solution goes further and prevents such data from leaving the machine at all.
