We will dive deep into the JPEG algorithm and then explore numerous published hiding techniques, explained in plain English (as opposed to Ph.D. mathematical lingo). Some techniques are extremely difficult to detect, while others have high capacity (15% to 30%). You will be amazed at how much data can be hidden in a JPEG with almost no visible change (and ZERO quality degradation), even when comparing images side by side. Then, we'll discuss several approaches to automated detection. We will demonstrate detection against the techniques applied. The entire talk is sprinkled with images and live demonstrations. Finally, I will present a customized implementation with full cryptography and detection mitigation. Best of all, you get the program to use yourself - this will be fun!
