摘要:
提出一种空间域信息隐藏算法。该算法结合了LSB和MSB的优点,将灰度值划分成一个个等长度区间,在每个区间都嵌入信息。信息嵌入是通过修改灰度值,而灰度值的变化是在区间范围内的,由于区间的范围较小,从而能够保证引起的图像失真是不可觉察的。同时考虑人类视觉系统的相关特性,选择出可用像素位置来嵌入信息,放弃不可用像素位置,进一步提高不可觉察性这一技术指标。实验结果表明,该算法隐藏容量较大,有较好的鲁棒性且易于实现
Abstract:
An information hiding algorithm for images is proposed based on section of them, the algorithm combines the advantage of the LSB and MSB, dividing the gray value into several sections which have the same length, embedding the information into the sections. Because the information embedded by changing the gray value in the scope of the section and the scope of the section is very little, as a resuit, the changes in the cover image were much imperceptible. Taking the relevant characteristics of the human visual system into account, select some sites of usable pixel to embed the information and discard some sites of unusable pixel. Experiments results show that, the algorithm has a large capacity of hiding information and a goodish robustness, at the same time, the method is easy to implement
