基于多目标规划的同义词替换信息隐藏模型

An Information-hiding Model Using Synonymous Substitution Based on MOP

从含密载体这一个物理信道抽象出秘密信息和原始载体分别到含密载体的两个逻辑信道,前者关联信息隐藏容量,后者作为载体统计保真约束的系统接口,通过建立多目标规划模型来求解信息隐藏函数,使得信息隐藏函数的设计可受原始载体、秘密信息的分布以及系统统计失真指标控制.MATLAB数值实验结果说明该算(?)可以有效的寻找到最优的信息隐藏函数.

From the stego carriers as a physical channel abstract out secret information and the original vector respectively into two logical channels. The former is associated with information hiding capacity; the latter is taken as system interface with the carrier statistical fidelity constraints. By the establishment of multi goal programming model, the information hiding function is solved. This design makes the information hiding function can be adjusted by the original carrier, secret information distribution and distortion of statistics index control system. MATLAB numerical experiments show that the algorithm can effectively find the optimal information hiding function.
