Anti-cropping digital image watermarking using Sudoku

Anti-cropping digital image watermarking using Sudoku

Many digital image watermarking schemes have been developed to embed copyright information into an image. However, an attacker may reuse parts of a watermarked image by cropping out unwanted parts. Several techniques have been designed to overcome this attack but due to their limited redundancy appr...
