Abstract:
It is important to protect digital pictures and detect tampered image locations in digital Cyberspace. In this study, we propose an image authentication scheme based on digital signature. The proposed scheme is capable of detecting if certain blocks of an image have been altered. The block can be as small as 86 image pixels.
