Abstract: The image processing is the technology which is applied to process digital information in the form of pixels. The watermarking is the scheme which secure sensitivity image. The various schemes are proposed for the generation of watermark images. In the previous research work, the scheme of chaotic maps with Arnold transformation is used for the image encryption. The scheme of discrete wavelet transformation is applied for the image embedding. The bit selection for the image embedding is selected randomly which is inefficient approach. When the bits are selected randomly, the quality of watermark image degrades.In this research work, the gray level cooccurrence matrix algorithm is applied which select the embedding bit dynamically. The proposed scheme is implemented in MATLAB and compared with existing in terms of peak signal noise ratio, magnitude signal error and bit error rate.
