In recent years, a greater interest in steganography is growing as an effective method of protection of still images, allowing you to keep the information confidential. In this paper we assessed robustness to hide information in the frequency domain of still images. Using qualitative and quantitative characteristics determines the optimal values for the Corvi method.
