Abstract :
This paper proposes a wavelet watermarking scheme for copyright protection of digital images. A secret sort is generated from the low frequency sub-band and used to improve the embedding intensity. From the experimental results, the proposed scheme is robust to withstand the wide variety of image processing attacks such as JPEG compression, scaling, cropping, and filtering attacks.
