Abstract

Here we propose a new technique for the Watermarking to withstand the geometric attacks, which may occur during the transmission of the watermarked image. The underlying system was based on Direct Sequence Code Division Multiple Access (DS-CDMA). The algorithm for the normalization had been formulated for use in black and white images. The watermark was spreaded across the carrier image by using the pseudo-random noise sequences of optimal period and retrieval was made by the use of correlation. Private Key technique is used so the transmission is very secure. Matlab was used to implement the algorithm discussed here.
