Abstract

Steganography is a branch of covert communication science, that the purpose is to hide the existence of information.Versus, the purpose of steganalysis is to detect and/or estimate potentially hidden information from observed data with little or no knowledge about the steganographic algorithm or its parameters. Although, the color images is common and have high capacity steganography, but researches in hiding information in color images is less than grayscale images. In this article, we have studied steganography and steganalysis methods in color images using color space information (such as RGB, YUV, YIQ, YCbCr and HSV color space) and proposed new methods in two domains. In steganography domain, we have proposed a simple and robust method for hiding information in the YUV and YCbCr color images using color spaces, that recognition of the message has become more difficult due to the use of conversion coefficients. The proposed method is evaluated by several famous steganalysis, and the results show that resistance of this method enhanced in comparison RGB color space. In steganalysis domain, we have examining the different color spaces and we have proposed a new general steganalysis method that based on spatial correlation of adjacent pixels in different color spaces components. It is independent of the type of steganography designed and has good detection. In general, the results of the two methods
