摘要

This paper presents a robust reversible data hiding scheme in wavelet domain. The proposed scheme divides the permuted image into non-overlapping blocks and then gets sub-blocks. The generated sub-blocks are transformed by discrete wavelet transform and the corresponding low frequency regions are gotten, respectively. The gravity centers of low frequency regions in every non-overlapping block are very similar. These gravity center pairs are utilized to embed secret data since the insensitivity of the gravity centers to malicious tampering. Experimental results show that the original image can be recovered without any distortion after the hidden data have been extracted if the stego image has not been altered. Meanwhile hidden data can still be extracted without error when the image is compressed by JPEG and JPEG2000 to a certain extent. Compared with some existing literatures, the security, payload and robustness of the proposed scheme are significantly improved.
