A Novel Watermarking Algorithm for Color Images Based on Discrete Wavelet Transform

Abstract

Abstract-It is very easy to copy and distributed the digital data illegally. There are many methods for solving this issue like intellectual, material right protection and Copy right protection for authors, owners, distributors. As the advancement, invisible double digital watermarking technique has received considerable attention. This paper gives a robust digital watermarking algorithm for color images based on discrete wavelet transform. Here, we choose a suitable method to watermarking algorithm for color images based on Haar discrete wavelet transform. The experiment result are very well, clearly represent the transparence and robustness of the algorithm. The experiment result shown that this algorithm is also secure to various attack.
