SYSTEM AND METHOD FOR CONTENT-BASED EMAIL AUTHENTICATION

摘要

One embodiment of a system for content-based email authentication includes an email server (118) configured to receive an email from a client (112), a content identifier generator (116) configured to generate content identifiers for an email by applying a hash algorithm to content of the email, the email server further configured to append the content identifiers to the email before sending the email. The email server (118) is further configured to receive a second email from a network (120), the second email having appended content identifiers. The content identifier generator (116) is further configured to generate content identifiers for the second email, and the email server is further configured to compare the generated content identifiers with the appended content identifiers and if the generated content identifiers and the appended content identifiers match, the email is deemed authentic and the email server (118) is configured to send the second email to a client (112).
