摘要：Digital Hiding information has emerged as a new area of research in an attempt to prevent illegal copying and duplication. In this paper, represent both method i.e. DCT&DWT based algorithm for watermarking in digital image .In order to compare the imperceptibility &robustness of both the algorithms make use of simple attacks such as resizing rotation& copping. Index Terms- Digital watermarking, discrete cosine transform (DCT),discrete wavelet transforms(DWT), Peak signal to noise ratio (PSNR),Mean squared error (MSE).
