基于多重压缩与加密的信息隐藏方法

The Method of Information Hiding Based on Multiple Compression and Encryption

混沌系统具有对初始值的极端敏感性,具有白噪声的统计特性以及伪随机性且易生成的特点。二维条码容量大,成本低,纠错能力强并且能够自动识读,论文将二者结合起来,进行多重压缩与加密处理,即首先对信息进行压缩及混沌加密处理,然后利用二维条码来实现信息的隐藏、存储、传输和自动识读。实验表明,该方法不仅能够实现信息的保密性与安全存储,同时还能够实现信息的自动识读。

Chaos system is very sensitive to original value.Chaotic sequence is randomicity,complexity and has the characteristic of white noise.Two dimension barcode has many advantages such as large capacity,high error correcting capability,low cost and automatic recognition.So combining the chaos system and 2-D bar code and realize multiple encryption and compression,we encrypt the image information by chaotic sequence and then realize the storage, transmission and automatic recognition of information by 2-D barcode.Experiment results show that the method not only can implement the confidential and security storage of information,but also can realize the automatic recognition.
