Patent ID: 8250159

Claim:
A system, comprising: a computer-readable storage device, comprising: pre-rendering logic that receives a message containing unrendered text and a non-text element intended to thwart a junk filter by varying the unrendered text and that renders the message in a user—perceivable format; converting logic that converts the rendered message into a text-only message by removing the non-text element of the rendered message and rendering words and phrases of the rendered message into text, the converting logic mitigating an affect of the non-text element; and filtering logic that filters the text-only message based upon predetermined content related to a degree of visibility of user-perceivable content of the rendered message, the filtering logic including weighting logic that adjusts a weighting parameter associated with the text of the text-only message to determine if the text should be removed, the filtering logic further making a determination of whether to handle the message as a junk message or a legitimate message based at least in part on a number of images associated with the text-only message and a total area of the images associated with the text-only message.
