In this paper, we propose a reversible data hiding scheme using (5, 3) Hamming code. A cover image is partitioned into blocks of five pixels. An adjusted (5, 3) Hamming code method is then applied to find a possible modification position in these blocks to conceal message bits. The estimated position is used to determine the started pixel in the next block and this pixel may belong to the current block of pixels. This means that the overlapped pixel blocks are employed in the proposed scheme to hide secret data. As a result, the proposed scheme provides an average embedding payload reaches to 1.2 bits per pixel (bpp). The embedding positions are also utilized as a secret key to protect the hidden message from extracting attacks and extra information in the image recovering process. An original image can be recovered with no error after an extraction process has been completed. The experiment results obtained from 10,000 natural images in BOWS-2 prove that the proposed scheme can achieve a higher embedding rate, better stego-image perceptual quality, and higher security against detection and extraction attacks compared with the existing approaches.

在本文中，我们提出了一种使用（5，3）海明码的可逆数据隐藏方案。封面图像分为五个像素的块。然后，应用调整后的（5、3）汉明码方法在​​这些块中找到可能的修改位置，以隐藏消息位。估计位置用于确定下一块中的开始像素，并且该像素可以属于当前像素块。这意味着在提出的方案中采用了重叠的像素块来隐藏秘密数据。结果，提出的方案提供了平均嵌入有效载荷达到每像素1.2位（bpp）。嵌入位置还用作秘密密钥，以保护隐藏消息免于在图像恢复过程中提取攻击和额外信息。提取过程完成后，可以无错误地恢复原始图像。从BOWS-2中的10,000个自然图像获得的实验结果证明，与现有方法相比，该方案可以实现更高的嵌入率，更好的隐秘图像感知质量以及更高的检测和提取攻击安全性。
