A Survey on various approaches used in digital image watermarking using DWT SVD

Computer Engineering

The recent advent in the field of multimedia proposed a many facilities in transport, transmission and manipulation of data. Along with this advancement of facilities there are larger threats in authentication of data, its licensed use and protection against illegal use of data. Digital watermarking is one of the most recent proposed systems to observe the authentication of licensed user over e-commerce applications and finds its uses in illegal applications like copying the multimedia data e.g. images, audio, video. The watermark indicates that data is containing copyright or not. To propose a measure against the illegal use of the images different available watermarking standards are studied. Then by taking the human visual system into consideration an algorithm is designed. This paper conducts a literature syrvey of watermarks and its various aspects. It describes the previous work done on digital watermarking schemes and their results. Potential applications are discussed, and implementation plan of the project is presented.
