摘要 RQP算法在对真彩图像加密信息的检测中十分有效,但对短加密信息检测和定位方面存在缺陷.针对此提出了一种改进的RQP算法,改进方法利用了分块的思想,分块后进行二次隐藏,通过对统计特征值进行比较检测、定位隐藏信息.实验表明改进后的RQP算法能很好地弥补原算法的不足. The raw quick pairs（RQP） algorithm is a very effective method in true color detected images, but it has defect on the detection and location of short hidden messages. So an improved RQP method based on original method was described. The underlying principle of the improved method was generating a new image from the received image by blocking. It used the statistical measure of compared Eigenvalues for detecting and localization. The experimental results showed that the improved RQP method is valid.
