“…We have used BCH coding with (31,16,3), where 16 are the actual, and 31 are the physical bits while up to 3 bits can be corrected. We have also used (31,11,5), which survives up to 80% JPEG compression. But when we increase the ratio of physical/original bits, the watermark payload becomes high and the PSNR degrades.…”

ABSTRACT: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.

“…One of the main factors is the emergence of certain complex issues related to the security of digital content [10,18,20,24]. Watermarking is an important technique for transmitting secret information in cover media without arousing the attention of malicious attackers [28,42,43].…”
