An Approach for Detecting and Restoring Tampering in Digital Image Watermarking

In addition to ensuring image authenticity, watermarking aids in the recovery of digital images that have been altered or tampered with during transmission. Although many techniques have been developed for embedding the watermark that results in recovering itself of photos, they only effectively work in the uncompressed multiple domains, leaving images vulnerable to attacks on image compression, such as noise addition. In order to effectively detect tampered areas and assure self-recovery of JPEG images, we offer a solution to address these issues in the JPEG domain. Source code compresses the original image, while channel code protects it from tampering. As a result, the image will be compressed and then used as the watermark which is embedded. The approach proposed is successfully combined with these JPEG images, producing increased image quality as well as strong performance against noise attacks.
