N2 - This paper presents an improved method of the reversible data hiding for JPEG images proposed by Xuan, et al. The conventional method embeds data into the JPEG quantized 8 × 8 block DCT coefficients. In this method, we found that the blocks, located in the noisy part of the image, are not suitable for embedding data. The proposed method can judge whether a block consisted of 8 × 8 DCT coefficients is located in smooth part of image by using the DC coefficient of neighboring blocks. Our method can avoid the noisy part for embedding. It results in a better performance in terms of capacity-distortion behavior.
