Image-watermarking is known as a process of embedding copyright and protected information in image bit components. It had been already proposed in last recent years to solve the issue of unauthorized manipulation and distribution of digital images. In this research study, the algorithm is based on cascade of powerful logical transforms. In this paper we proposes a novel method of blind multiple watermarking technique for color images. To protect the image copyright authentication and help to validate the copyright ownership of multiple owners. The cover image information is converted to Red, Green and Blue components image in first step. Green and Blue component of image is transformed in wavelet domain Discrete Cosine Transform (DCT) for decomposition techniques. A binary watermark of 64x64 pixel is embedded into the green and blue component’s of cover image, is transformed block by modifying the some-middle bands significant with AC coefficients using the repetition code. We select sub bands using repetition code and zigzag techniques. The watermark is modified by the scrambling use of Arnold transform. In the proposed paper, robustness and quality is tested with image parameter like Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE),and Normalized Correlation Coefficient (NCC). Further, the proposed paper have comparison with related watermarking schemes.
