Abstract—Due to the rapid evolution in internet technology and high speed networks the use of digital data has been increased. Digital data such as audio, video and images are easily created, copied, processed, stored and distributed among the users. To ensure security and protection of digital data new technology has been developed called as a digital watermarking. Digital watermarking is a technology which embeds additional information in the host image to ensure security and protection of the digital data without effecting original data. The purpose of digital watermarking is not to restrict use of digital data but it can be provide copyright protection and authentication against unauthorized uses. In this paper detail study of watermarking definition, concept and the main contribution of watermarking process in which watermarking should be used, features, techniques, Application, challenges and performance metrics of watermarking and comparative analysis of watermarking techniques are included.
