With the advances in digital technology, manufacturing cost of digital camera, multimedia hand phone and PDA is dropping and digital broadcasting is becoming mature. The transmission of digital media through the Internet is getting very popular. Not only multi-level images, video and audio are in digital form, binary images are also digitized in the applications including 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 talk provides a review on the latest developments in information security in text document, the challenge in cryptography, the fast development of biometrics, and the introduction of 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 will be discussed and analyzed. Distortion measure scheme is proposed to match with the human visual perception. Data hiding technology combined with secured authentication techniques will be discussed for secured media transmission and tracking.
