The transmission of digital media through the Internet is also getting increasingly popular. Apart from multi-level images, video and audio are in digital form and binary images are also getting digitized in applications involving legal documents, digital books, contracts and electronic drawings. Recently, data hiding techniques have been proposed for ownership protection, copy control, annotation and authentication of digital media. This tutorial provides a review on the latest development in data hiding for authentication in digital media communication. In particular, security in black and white, an emerging technology for the digital media will be delivered. Different data hiding techniques for binary images using pattern based, contour based, and transform domain based approaches will be discussed and analyzed. A distortion measure scheme is proposed to match with the human visual perception. Data hiding technology combined with secure authentication techniques will be discussed for secure media transmission and tracking. Stegananalysis and image forensic in data hiding will also be included in the tutorial.
