Presentation

Steganography is the practice of hiding a message “in plain sight” inside an image, video, sound, text, or file. The practice goes back centuries, and in recent years has seen a rise in use for digital watermarking.
Unlike cryptography, steganography seeks to hide even the presence of a message.
Steganography can be used for communication, leak prevention, or copyright protection. We’ll look at steganographic techniques, analysis, and detection through the lens of digital watermarking.
