چکیده مقاله:

Today, steganography is known as an effective way to convey secret data. A wide range of techniques has been developed in this context, each seeking to improve certain problems of theirown. The current paper presents a method by which, when comparing three color values at each pixel to the correspondingones from all its eight neighbors, it is attempted to embed message bits into the two least significant bits of a color component of an image that an acceptable color difference has happened in. Due to the mechanism proposed, this method makes the message difficult to be discovered. However, since messagedetection does not need to insert additional data to identify the colors containing message bits, changes in image is less and the imperceptibility is higher
