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