The main concern is to deal with implementing Steganography for images for the improvement in security as well as image quality. The stego-image quality will be improved by using difference between two stego-pixels. Here, the certain least significant bits of cover image are selected from the current stego-pixel. Such a current stego-pixel defines the next stegopixel. In this technique every pixel of RGB based 24 bit image using LSB technique where 8 bits are used to show red color, 8bits show green color and last 8 bits for blue. first two bits from 8 of them shows the color of next pixel using RGB color combination then 3rd bit will be ignored. then next two bits defines the difference between current and next pixel.Again 6th bit will be ignored and next two bits that is 7th and 8th defines how much bits of signature will be hidden. The proposed method shows better enhancement to Least Significant Bit technique with consideration to more secured data.
