Free registration required

Executive Summary

Image spam is a type of e-mail spam that embeds spam text content into graphical images to bypass traditional text-based e-mail spam filters.

This paper proposes a more desirable comprehensive solution which embraces both server-side filtering and client-side detection to effectively mitigate image spam.
