ABSTRACT
Digital Watermarking provides techniques to hide watermarks into digital content to protect it from illegal copy or reproduction. The prevalent techniques of digital watermarking in spatial domain cause the watermarked image to loose its image quality termed as Robustness and fidelity. Several techniques have been devised to optimize the Robustness and fidelity with given information content. Recently, genetic algorithms have become quite popular in artificial intelligence area due to their evolutionary nature and their special significance for optimization in several areas. This paper is an attempt to propose the conceptual background of technique based on genetic algorithm which may help to optimize the fidelity and robustness aspect of watermarking. Genetic algorithm may help to search appropriate locations in cover images to insert watermark so that fidelity or robustness may be optimized. Based on a specific requirement, a suitable fitness function may be selected.
