Abstract—In this paper, data protection based on image watermarking using carious decomposition techniques. Digital watermarking system is widely used for security, data encryption in the real time system. The digital watermarking system is decomposed into various level of sub-bands using various multiresolution system. The watermark image is encrypted into the original input image to provide the watermarked image. It is implemented on the behavior of intellectual things need to applied for protection of the digital watermarking. The feature extraction is purely depends on the least significant bit method. The decomposition method is a robustness of least significant bit to increase the image quality of the system. The proposed method has been successfully implemented on the various real time images to protect the data.  The experimental results provides better results as comparted to existing methods.
