摘要
在对军事通信图像加密通信中的数据进行隐藏的过程中,数据融入方式是通过依据某种规律曲线的顺序扫描待隐藏数据的单元来实现的,导致传统的融合军事图像加密通信中数据隐藏算法,由于检测工具有规律可循,不容易逃脱检测,无法对军事图像数据进行有效的隐藏。提出一种采用随机融入方式的可逆数据隐藏算法,直接提取军事图像边缘特征,充分挖掘军事图像视觉屏蔽特性,通过军事图像分块方差对其边缘特性进行刻画,确保军事图像边缘的完整度,构建军事图像采样子图与参照子图间的军事差图,通过数据隐藏的提取方法,将隐藏军事图像差图数据合成相应的数据隐藏码流,完成所有军事差图的置乱操作,将置乱后的军事差图中的隐藏数据按照数据隐藏的正确率进行度量,实现军事图像加密通信中的数据隐藏。仿真结果表明,采用所提方法对军事图像加密通信中的数据进行隐藏的效果与隐藏容量均优于传统方法,验证了所提方法的有效性。
The paper presented a reversible data hiding algorithm using random integrated mode. Edge features of military image were directly extracted to fully excavate the visual masking properties of military image. Through military image block variance,the edge features was depicted,ensuring the integrity of the military image edge. The acquired sub-image of military image and the military difference image between reference sub-images were constructed. Through the extraction method of data hiding,the hiding data of difference image in military image were composed to form the corresponding data hidden code stream,to complete the scrambling operations of all military difference images. The hiding data in military figure after scrambling were measured according to the accuracy of the data hiding,to realize the data hiding of military image encryption communication. The simulation results show that the effect and hiding capacity of using proposed method for the data hiding in military image encryption communication are superior to traditional methods,verifying the effectiveness of the proposed method.
