The reversible data hiding in encrypted images by MSB prediction of P. Puteaux and W. Puesch not only provides high embedding bit-rates, but also entails a very low mathematical complexity. This correspondence investigates its security and shows flaws in embedding imperceptibility, unauthorized detection/removal of embedded data and unauthorized access to image content. Secure solutions are discussed.

基于MSB预测的加密图像中可逆数据隐藏的安全性

通过P. Puteaux和W. Puesch的MSB预测，隐藏在加密图像中的可逆数据不仅提供了很高的嵌入比特率，而且还具有非常低的数学复杂度。该信函调查了其安全性，并显示出嵌入隐匿性，未经授权检测/删除嵌入式数据以及未经授权访问图像内容方面的缺陷。讨论了安全解决方案。
