Data encryption is becoming an ever more important aspect of the world in which we live. Business, government, and military requirements continue to increase. Most of the concepts surrounding encryption involve taking the data, encrypting it, and allowing others to understand that the data has been encrypted and then trying to break the encryption (if desired). There is, however, an emerging field of encryption called "steganography" in which data is "hidden in the clear." Thus, for any given observer, there wouldn't be any noticeable evidence that data was "hidden" in a given object (e.g., a picture). This disclosure details a method (algorithm) for "hiding" data within a picture. While hiding data within a picture is certainly not a new idea, the value of this disclosure is found in the methodology of performing the encryption.
