In this paper, we propose a novel fragile watermarking scheme based CRC checksum and public key cryptosystem for RGB color image authentication. ...
These data, in particular the images should be protected from tampering. The solution is the use of fragile watermarking. ...
We are grateful to Dr Redha BENZID and Dr Rachid SEGHIR for early stimulating discussion and for their valuable comments and suggestions which lead to substantial improvements of this paper. ...

In this paper we analyze three authentication watermarking schemes and point out their security flaws. The first scheme is the color authentication scheme in [1]. ...
The scheme is not secure in the sense that as long as an attacker obtains one authenticated image, he is able to forge authentic images without the secret key. ...
WONG'S AUTHENTICATION SCHEME Wong et. al [2] described two authentication watermarking schemes: a secret key scheme and a public key scheme. ...
