Digital Watermarking and Steganography: Fundamentals and Techniques - CRC Press BookModern 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.

Mee, C. When PSNR is higher than 35 dB watermarked image has a very good quality and the eye could hardly tell the difference between the original and the watermarked image. A digital fundamentlas is a kind of marker covertly embedded in a noise-tolerant signal such as audio.
Technology Quarterly. Fragile watermarks are commonly used for tamper detection integrity proof? Chapter 3 provides mathematical fundamentals, random sequence generati. The latter term refers to information-hiding!
Chapter 1 introduces the field and distinguishes watermarking from steganography. Detection and attacks for these systems will then be outlined, and three representative techniques will be described in depth. Digital image techniquws is a process of hiding valuable digital data of any kind so that it can be kept intact. The marks often were created by a wire sewn onto the paper mold.
The final two chapters, 10 and 11 are devoted to steganography. Unfortunately free access digital multimedia communication also provides virtually unprecedented opportunities to pirate copyrighted material! The genetic algorithm GA based watermarking technique solves the rounding error problem and provide an efficient embedding approach. Marvel, and C.
