可逆图像数据隐藏(RIDH)是一种特殊的数据隐藏技术，它可以在数据提取的基础上完美地重建宿主图像。由于这种可逆性，RIDH在许多关键场景中被广泛采用。然而，现有的几乎所有方法都着眼于提高容量失真性能；隐藏能力被含糊地称为人类观察者的感知不知不觉。在这篇文章中，我们展示了流行的RIDH框架，预测误差扩展直方图移位(PEE-HS)，嵌入后会留下相当明显的痕迹，承受着暴露数据隐藏行为的风险。为了解决这一问题，提出了几种对策来隐藏嵌入痕迹，同时保留传统的可逆性特征。实验结果证明了该方法的有效性。我们相信，这份简报可能会揭示里德的安全方面。
Reversible image data hiding (RIDH) is a special class of data hiding techniques, where the host image can be perfectly reconstructed upon data extraction. Due to this reversibility property, RIDH has been widely adopted in many critical scenarios. However, almost all the existing methods focus on improving the capacity-distortion performance; and the hiding ability is ambiguously referred as the perceptual unawareness of a human observer. In this brief, we show that the prevalent RIDH framework, prediction error expansion histogram shifting (PEE-HS), would leave quite obvious traces after embedding, suffering the risks to expose the data hiding action. To address this issue, several countermeasures are proposed to conceal the embedding traces while retaining the conventional reversibility feature. The experimental results demonstrate the effectiveness of our proposed method. We believe this brief could shed light on the security aspect of RIDH.
