Secure messaging system with personalization information

摘要

Personalization images are included in email messages to combat phishing attacks in which an attacker attempts to trick a user into divulging sensitive information over the Internet. When a recipient of an email message receives a message, the recipient can visually inspect the personalization image in the message. If the personalization image is missing or if the personalization image is not valid, the email recipient is alerted to the possibility of a phishing attack. Email message content may be encrypted. A gateway associated with an email message sender may be used to perform encryption operations on the message content. The gateway may create an html version of the email by placing the encrypted message content in an html wrapper. An image reference corresponding to the personalization image may be embedded in the html version of the message.
