Steganography is the method by which we hide information in ordinary files like text, audio, video, images, etc. In this paper, we have explored image steganography using the least significant bit (LSB) approach combined with AES-128 encryption. We proposed to change the order of traversing the RGB planes while embedding a secret message in the image. The order of traversal was determined by image attributes like file type and resolution so that the steganography capacity of the image remains unchanged. RMSE and PSNR were used as error and performance metrics respectively. The experimental results confirmed that the method proposed was successfully implemented without increasing the number of bits embedded in the image.
