The fundamental reason of watermarking invention was to protect originality of image message in the first place from outside attack. The quality of image depends on its ability to survive against various kinds of attacks that try to remove or destroy the originality. However, attempting to remove or destroy the message meaning should produce a noticeable debility in image quality. The robustness is a factor that plays an important role to test and verify the algorithm whether it will withstands against these attacks or not. In this paper the robustness of the proposed algorithm [15] for secret image share in Visual Cryptography Scheme is identified. The robustness of the image against various attacks, specifically image blur attack and image sharp attack are tested. The study of calculated PSNR value signifies the proposed algorithm withstands successfully on these attacks.
