Reversible Data Hiding (RDH) is one of the most well-known methods adopted for concealed communication. One of the major issues in RDH is the overflow/underflow which exists in almost all the embedding techniques. This is a major issue which hinders the hiding capacity in many existing techniques. In the proposed novel LSB ODD/EVEN embedding algorithm, neither histogram modification (which involves shifting) nor difference expansion (which involves shifting and expansion of error) techniques are involved. No overflow/underflow problem is reported in the proposed method and involves multilayer embedding. Performance of this approach or any data hiding schemes are usually measured in terms of MSE, PSNR, and SSIM. After multiple layer of embedding the PSNR for 1.5 bpp stands at 43 dB approximately. This approach is tested over standard test images that includes medical images also and compared with well-known existing schemes.

可逆数据隐藏（RDH）是用于隐藏通信的最著名方法之一。RDH中的主要问题之一是几乎所有嵌入技术中都存在的上溢/下溢。这是一个主要问题，阻碍了许多现有技术的隐藏能力。在提出的新颖的LSB ODD / EVEN嵌入算法中，既不涉及直方图修改（涉及移位），也不涉及差异扩展（涉及误差的移位和扩展）技术。所提出的方法没有报告上溢/下溢问题，并且涉及多层嵌入。通常使用MSE，PSNR和SSIM来衡量此方法或任何数据隐藏方案的性能。多层嵌入后，1.5 bpp的PSNR大约为43 dB。
