Data-Hiding Codes

摘要: This tutorial paper reviews the theory and design of codes for hiding or embedding information in signals such as images, video, audio, graphics,and text. Such have also been called watermarking codes; they can be used a variety applications, including copyright protection digital media, content authentication, media forensics, data binding, covert communications. Some these applications imply presence an adversary attempting to disrupt transmission receiver; other involve noisy, generally unknown, communication channel. Our focus is on mathematical models, fundamental principles, code techniques that are applicable hiding. The approach draws from basic concepts theory, coding game signal processing,and illustrated with problem images.
