Abstract

In recent years, access to multimedia data has become much easier due to rapid growth of the internet. While this is usually considered an improvement of everyday life, it also makes unauthorized copying and distributing of multimedia data much easier, therefore presenting a field of watermarking.Many literatures have reported about Discrete Wavelet Transform (DWT) based watermarking for data security since they are found to be robust against image processing attacks when compared with spatial domain. In this paper, an attempt is made to develop a watermarking scheme based on DWT and extraction using Independent Component Analysis (ICA).FastICA is proposed and implemented for extraction. In this work, proposed DWT with Fast ICA is compared with DWT based Self Reference with Non ICA technique. Simulation results show that proposed technique produces better PSNR and similarity measure. The robustness of the proposed scheme is evaluated against various imageprocessing attacks.
