Mastering Steganography: Secrets of Concealing Information with John Oritz 🎯

Clip 1/6
Speaker: John Oritz · SRA International

Steganography is a discipline of computer science whose aim is to conceal the existence of information. Steganography synergizes various technologies including data compression, digital signal processing, information theory, data networks, cryptography, coding theory, and the human audio and visual system. Strap on your seatbelt. I will present some key concepts of steganography, describe a number of basic and advanced spatial and transform domain techniques (with lots of pictures and sounds for the attention-challenged), and demonstrate these techniques using custom steganography software. The demonstrations include a Least Significant Bit (LSB) technique, High-Capacity Hiding in Jpegs, and time modulation in audio.
