Texas Instruments: Numb3 Rs: Now You See It, Now You Don't

Based off of the hit television show NUMB3RS, this lesson is an introduction to a "different" type of coding, called steganography. In Steganography, images (or text) are split into layers, and then distorted in such a way so as to appear as random "noise." To decrypt the message or image, different layers must be stacked, thereby eliminating enough noise so as to leave a readable message. Student experiment with encrypting and decrypting messages using steganography.
