Information Hiding: Steganography and Watermarking | SpringerLinkDigital Watermarking. Fundamentals and Techniques. CRC Press, Return to Home Page. Watermarking is a field of signal processing and pattern recognition that has enjoyed accelerated interest since the mids directly in parallel to the explosive growth of the Internet. The reason is that, although the Internet enables easy, global distribution of documents, this same advantage is a security disadvantage. How do you control distribution to only those who have legitimate access or who have purchased access rights?

Modern information-hiding techniques conceal the existence of communication. The primary facets of information hiding, also known as data hiding, are payload size, robustness to removal, and imperceptibility of the hidden data. In general, digital techniques can be divided into three classes: invisible watermarking, steganography, and embedded data. However, it is desirable for all classes to successfully conceal the hidden information from applicable detectors. Invisible watermarking, generally employed for copyright protection, traitor tracing, and authentication, forgoes a large payload amount for stringent robustness. Steganography, used for covert communication, pursues increased payload size while sacrificing robustness.
