Teknos Submission

Name: William Barratt
Title: Steganography Using Computer Images

Background: The definition of "steganography" is "hiding a secret message within a larger one in such a way that others can not discern the presence or contents of the hidden message." In computer images, this means modifying the pixel values in a particular way to incorporate hidden data, without causing a noticeable change in the appearance of the image.

Description: An investigation into methods of steganography using computer images, covering various steganography algorithms and image file types. This project's goal is to find a combination of algorithm and image file that is hard to detect and allows for a large amount of data to be hidden. Beginning with the obscure P2 PGM image file type, the project will culminate with an iteration supporting the common PNG file type.

Visuals: The visuals I have available for a Teknos submission include screenshots of the program running in command-line, "before-and-after" pictures of images, and a contrived image that is useful only for an advertisement.
