Abstract: Now a day’s internet plays a vital role in carrying information from one place to the other. This information which is transmitted is digital multimedia which includes images, audio and also video. Attacking of digital data is very easy and easily monitored by anyone through the internet. Therefore in order to protect these attacks digital watermarking is introduced. This survey paper describes digital watermarking in detail and explains theory, techniques and its application especially to digital libraries. This paper tells about digital image watermarking scheme with blind detection for copyright verification. The binary watermarks are embedded in the wavelet domain of an image using the wavelet domain of an image using the discrete wavelet packet transform (DWPT) and quantization of the selected dominant coefficient.
