With rapid growth in computer network and information technology, a large number of copyrighted works now exist


digitally as a computer files, and electronic publishing is becoming more popular. These improvements in computer


technology increase the problems associated with copyright enforcement and thus future developments o f networked


multimedia systems are conditioned by the development of efficient methods to protect ownership rights against unauthorized


copying and redistribution. Digital watermarking has recently emerged as a candidate to solve this difficult problem. In the


first part of this paper we introduces an overview to digital watermarking: The general framework, its main applications, the


most important properties, the main aspects used to classify watermarking, and we discuss the attacks that watermarking


system may face. Finally we introduce human visual system and its interaction with watermarking as well as some open


problems in digital watermarking. In the second part we introduces an overview of watermarking in frequency domain. The


general properties for frequency domain as well as specific properties for each sub-domain are introduced. The sub-domains


considered are discrete cosine domain, discrete wavelet domain and discrete Fourier domain. We also introduce some


different watermarking techniques in each category
