In an earlier paper, “Techniques for Data Hiding,” the overall goals and constraints of information-hiding problem space and a variety of approaches to information hiding in image, audio, and text were described. In this sequel, information-hiding goals and applications are expanded beyond watermarking to encompass the more general concept of information tagging. As a framework for illustrating these concepts, multiple-bit and midlevel image-representation information-hiding techniques are described. A range of applications, including anticounterfeiting and authentication, is explored.
