摘要
提出一种像素随机映射的快速方法,将该方法与像素字节低位隐藏信息的最低有效位技术相结合,讨论了将RGB彩色图像作为载体隐匿真彩色图像、灰度图像、二值图像及全息信息的方法.研究结果表明,该方法加密及解密效率高,载体图像具有较好的抗破译及抗剪切能力.根据隐藏信息的性质合理使用LSB技术,能在基本不影响载体图像质量的情况下较好地隐匿多种信息.
A novel fast method for pixel random mapping is proposed.Combining with the technology of information hiding of Least Significant Bit（LSB）,the RGB colour image used as a carrier image to hide real colour image,gray image,binary image and holography information are discussed.The experimental results show that this method has a high efficiency of encryption and decryption,and is robust to resist the attack of interference and image cutting.While the technology of LSB is applied properly according to the property of information hiding,the multiple information can be hidden well in carrier image while the quality of image is almost not influenced.
