• In this paper, we study on hiding external information into JPEG-XR compressed image. Our proposed method is based on flipping sign of the selected FCT (Forward core transform) components. Specifically, 4 × 4 blocks are first categorized into smooth and complex classes based on block energy. Then, FCT from the complex blocks are selected to hide information. To evaluate the proposed method, we consider three criteria, namely, image quality of the output image, available payload, and output image file size. Experimental results show that the proposed method achieves satisfactory payload and high image quality while maintaining the original file size.
