摘　　要：针对压缩感知技术应用于信息隐藏领域,传统的算法是利用高斯随机矩阵作为测量矩阵,载秘信息的透明度与计算时间有待进一步提高,利用LDPC矩阵作为测量矩阵进行计算,完成秘密信息隐藏,通过实验仿真与数据计算,该方法在不可感知性与计算时间损耗上均优于传统算法的同时,具有一定的鲁棒性。For compress sensing technology applied in the field of information hiding, the traditional algorithm was based on the Gauss random matrix as a measurement matrix, and the transparency of the carrier density information and computing time remains to be further improved, using LDPC matrix as a measurement matrix to calculate, we finished secret information hiding. And through the experimental simulation and data calculation, the method is superior to the traditional on imperceptibility and computing time loss, at the same time, it has a certain robustness of the algorithm.
