The secret information would be transmitted between the sender and recipient to raise the security requirement of multimedia items. Watermarking is the most often used method for adding security to photographs. In many cases, using a watermarking strategy to provide security is not viable. Because the security message is visible, hackers may add a watermark on the original image, just like the sender did, and then send the changed image to the recipient. The copyright information is available to everybody. The unique intrinsic fingerprint of the image source coders is used as proof for security to overcome difficulties in the watermarking technique. A forensic detector is built based on the inherent fingerprint of image source encoders. This detector determines which source encoder is being used, as well as the coding parameters and confidence measures for the output.
