摘　　要：基于图像的信息隐藏技术是信息安全领域的一个重要分支,其中的空域信息隐藏算法因隐藏容量大,实现简单而得到广泛应用.研究了几种经典的基于图像的空域信息隐藏算法,从隐藏容量、隐藏失真变化率、抗检测性和鲁棒性等方面分析它们的性能.理论分析和仿真结果表明,HUGO和WOW算法的整体性能明显优于LSB、Patchwork算法,而WOW算法的隐藏失真变化率和抗检测性比HUGO算法好,但它的算法鲁棒性却比HUGO算法差.The Digital Image Steganography is an important branch in the field of information security,in which the hiding algorithm based on spatial domain is widely used due to large hiding capacity and simple.Several classic hiding algorithms based on spatial domain were studied and compared from hiding capacity,hidden distortion rate of change,anti-detection and robustness analysis and other aspects of their performance.Theoretical analysis and simulation results show that the overall performance of HUGO and WOW are significantly better than the LSB and the Patchwork.The analysis results also show that the hidden distortion rate of change and anti-detection of WOW is better than the HUGO,but the robustness of WOW is worse than HUGO.
