The goal of this research is to create Efficient Privacy Preserving online communication System with help of VCS, Block DWT-SVD and modified Zernike Moment to prevent from attackers. In current Scenario online transactions are uses Client-server System. In that Server data will be modified by the attackers. VCS is Image Encryption technique Which Generate Binary Share image. One Binary share hide into cover image to get informative image. For that Block based discrete wavelet transformation (DWT) provide more redundant bit to hide more amount of data. For Rotation Scale Transform (RST) based attack by using transform based domain with modified Zernike Moment for rotational invariant pixel Selection. Also, find out some problems based on separate DWT and DWT-SVD with RST attacks by the attackers. The basic advantage of the system is that the image is moved before installing of the informative image and de-moved subsequent to inserting. Proposed methodology gives batter accuracy based on quality parameters PSNR and MSE value. The system will be used in Banking, Military and other online communication systems.
