摘要

基于混沌分组的思想

提出一种二维工程图的信息隐藏算法.该算法先获得工程图中的实体集

对实体的句柄进行处理后得到混沌系统的初值和迭代次数

根据迭代后得到的值进行分组

对同一分组的实体重复嵌入相同隐秘信息

从而实现信息的冗余隐藏.试验结果表明

该信息隐藏算法对图形修改攻击、旋转、平移以及均匀缩放等攻击具有较好的鲁棒性.

Abstract

An information hiding algorithm based on chaotic grouping is proposed.The entity set is firstly acquired from the engineering graphic

then some operations are executed to the handle of the entities

and the initial values and iteration times are gotten for iteration of the chaotic system.Group operation is processed according to the iteration results

and information hidden is achieved by embedding the same message in the entities in the same group.Simulation results show that the proposed algorithm is robust against the attacks such as modification

rotation

moving and equal scaling.
