Digital Watermarking is the technique to protect the images, which may be pirated by the other persons. Watermarking is one of the solutions to protect an image, however it is also used to protect audio and video. In watermarking one image is embedded into the image which we want to protect, using certain algorithms, we can’t see the embedded image. To increase the robustness and imperceptibility of watermark different variants of algorithms are used. There are different watermarking techniques which have its own advantages and disadvantages. Different algorithms are proposed to increase the robustness and imperceptibility. Cryptosystem concepts are also used in the watermarking to enhance the robustness and security. |
