Abstract

In this paper, we present a survey of several methods on robust digital image watermarking. Digital image watermarking, it is used as a solution to build the data transferring protected from prohibited interferences. Digital watermark methods are used in a variety of areas such as copyright protection, and vendor identification. In this paper we mainly concern on two methods: spatial domain and frequency domain. Some problems in spatial domain like Low hiding ability of watermark information, low PSNR among cover image and extracted secreted image, so a person can detect such algorithms. We discussed several transforms such as 2DWT, 2DCT,etc, in which the watermark is embedded into transformed constants of image for providing capacity and more robustness against watermarking attacks. It starts with overview, classification, features, framework, techniques, application, challenges, limitations, and performance metric of watermarking and a comparative analysis of some major watermarking techniques. In the survey our prime concern is image only.
