Abstract
This presentation shows a method to present e-mails to human users only, by encoding the body of the e-mail with a user defined keyword, attaching the distorted image of the keyword to the e-mail and sending it to the intended user. This keyword image is extracted and verified by the user in a CAPTCHA style test on the receive side to authenticate human user participation and then e-mail body is decoded and presented to the intended user.
