The protection of data can be done by several mechanism to secure and achieve authenticity and integrity of data. Data hiding is a technique in which a piece of information can be embedded to cover media data for security reason. So a digital watermarking can be used to protect the copyright of digital products. In such processes it is needed to maintain the original view of the host image. For evaluating the watermarking methods performance it must be concentrate on the robustness of watermarked image quality and restored image quality. For this purpose the preinserted encoding mechanism can be used in the discrete cosine transform domain. So a simulator preinserted code can address the next level of protection to perform various procedures for the sake of integrity and security.
