Use of digitized media is increasing due to rapid growth of internet and there is a sincere need of copyright protection of digital images. In order to protect ownership or copyright of digital image digital image watermarking techniques have been designed and implemented. The performance of a digital watermarking technique is indicated by the robustness of embedded watermarks against various attacks. Digital image watermarking can be done both in spatial as well as frequency domain. A comparative study of different digital watermarking techniques in spatial and transform domain has been provided in this paper. LSB technique is commonly used in spatial domain based watermarking, and in frequency domain based watermarking techniques, DCT and DWT are commonly used. This paper focuses on the various domains of digital image watermarking techniques and various attacks on watermarked images.
