A New Image Steganography Method Based on Pixel Neighbors and 6 Most Significant Bit(MSB) Compare

Abstract

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 their own. The current paper presents a method by which, when comparing three color values at each pixel to the corresponding ones 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 message detection does not need to insert additional data to identify the colors containing message bits, changes in image is less and the imperceptibility is higher.
