摘要

The increased use of multimedia applications pose more problems concerning the preservation of confidentiality and authenticity of the transmission of digital data. These data, in particular the images should be protected from tampering. The solution is the use of fragile watermarking. Fragile watermarking can be modeled as a problem of communication of a signal over a noisy and hostile channel, where the attack takes place. Indeed, the use of error checking algorithms appear natural. Cyclic redundancy check (CRC) code provides a simple, yet powerful, method for the detection of burst errors during digital data transmission and storage. CRC is one of the most versatile error checking algorithm used in various digital communication systems. In this paper, we propose a novel fragile watermarking scheme based CRC checksum and public key cryptosystem for RGB color image authentication.
