Now a days the transmission and distribution of the digital images by appending the digital signatures and content based image authentication schemes facing some triggers which are suitable for the insecure network and robust to transmission errors. The invasive distribution of digital images and the growing concern on their integrity and originality triggers an emergent need of authenticating corrupted images by transmission. To meet this need, this paper proposes a content-based image authentication scheme that exploits structural digital signature scalability in order to achieve a good tradeoff between security and data transfer.
