Each pixel within a digital image has 4 values. We can hide alphanumeric characters within the designated pixels by altering one of these values without the pixel itself changing all that much. We can add another step of complexity by randomizing where these pixels will show up on the image itself rather than keeping them all in one location going vertically or horizontally. Finally, we can add SHA256 encryption and password protect our secret message to ensure practically perfect protection. Give it a try!
