Digital Image Watermarking in Special and Frequency Domain

Abstract

Requirement of proficient and valuable copyright protection approaches is needed because of the prompt and fabulous evolution of multimedia and the outspread use of the Internet. For countering the copying, forgery and unauthorized handling of images and video system are required to tackle this issue. Due to lack of such methods, storing images over a public network is prime concern. In this paper, digital watermarking is implemented in special domain (LSB) and frequency domain (DWT) which reveals that DWT perform better than LSB. Two examples of each of digital image watermarking are taken under consideration and obtained results are compared. This comparison reveals that the DWT based digital image watermarking outperform the corresponding LSB based watermarking technique.
