高辐射分辨率（≥10bit）航空航天数字遥感影像已经逐渐成为空间地理信息获取的主要数据源。针对高辐射分辨率遥感影像的特性，提出了一种基于整数DCT变换的可逆信息隐藏算法，通过对整数DCT变换后的高频系数进行修改来实现待隐藏信息的调制嵌入，并提出了相应的容量提升和失真控制方案，且能够在精确提取隐藏信息的同时实现原始数据的完全无损恢复。实验结果表明，该算法具有较好的不可感知性，可以有效抵抗线性拉伸攻击，并且对于剪切、旋转、噪声，滤波等攻击都具有较强的鲁棒性。

High radiometric resolution (≥10bit) digital remote sensing image obtained by aeronautics and astronautics technology has gradually been the main data source of spatial geographic information. Focusing on the characteristic of high radiometric resolution digital remote sensing image, this paper presents a reversible information hiding algorithm based on integer DCT(discrete cosine transform), which uses a high frequency coefficient modification technique in the integer DCT domain to modulate the information, the corresponding embedding capacity increase scheme and distortion control scheme are also proposed. During the information extraction process, the original image can be perfectly restored with the embedded information accurately extracted at the same time. The results of experiment proved that this algorithm is invisible, can efficiently against linear stretching attack, and has better robustness to crop, rotation, noise or filter attack.
