Summary

Image watermarking has been proposed as a suitable tool to identify the source, creator, owner, distributor, or authorized consumer of a document or an image. It can also be used to detect a document or an image that has been illegally distributed or modified. The digital watermark, unlike the printed visible stamp watermark, is designed to be invisible to viewers. The bits embedded into an image are scattered all around to avoid identification or modification. Therefore, a digital watermark must be robust enough to survive the detection, compression, and operations that are applied on. This chapter introduces watermarking classification followed by a description of Spatial-domain watermarking and frequency-domain watermarking respectively. It presents the techniques of Fragile watermark and robust watermark follwed by the method of combinational domain digital watermarking.
