Image authentication is a challenging area of growing importance. Although a number of image authentication systems have been proposed in recent years but less attention has been paid to their evaluation. In this paper we analyze the JPEG compression tolerant image authentication scheme SARI , and show a number of ways of constructing fraudulent images that pass the verification test, hence defeating the system claimed security. We then show methods of modifying the system to make the attacks ineffective.
