The ubiquitous nature of digital network systems means that digital documents can be copied and distributed easily to large numbers of people with no cost. Individuals can download sound, picture and video records, and they can impart them to companions and they can control or adjust their unique substance. This is the reason there is an earnest need to ensure the copyright of such media. There are various advances that will give insurance from unlawful replicating. Advanced watermarking calculations were created to take care of this issue. To secure and less space data hiding and compression encryption through discrete shearlet transform (DST) and block based coding algorithm is present paper. According to efficient scheme is increase PSNR (peak signal to noise ratio), SSIM (similarity index) and decrease mean square error (MSE).
