Abstract
Abstract: Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet. For hiding secret information in images, there exists a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. Different applications have different requirements of the steganography technique used. For example, some applications may require absolute invisibility of the secret information, while others require a larger secret message to be hidden. This paper intends to give an overview of image steganography, its uses and techniques. It also attempts to identify the requirementsof a good steganographic algorithm and briefly reflects on which steganographic techniques are moresuitable for which applications. The proposed work improve the imperceptibility of steganographicapproach and developed new algorithm using modifying approach. A comparative analysis of the proposed algorithm with the existing techniques using the statistical hypothesis testing framework is introduced in the proposed work and also we have evaluated the performance on comprehensive set of color images.
