摘要
如何实现多媒体数据文件的可生存性存储一直是研究者关注的一个重要课题。结合超混沌映射特性,利用超混沌系统中的伪随机序列提出并用软件实现了一种新的图像可生存性存储方案。该方案既适合于软件实现,又能够实现图像存储的安全性及容灾性,并通过实验进行了相应的最优化分析。
How to realize the survivable storage of multimendia data files is always an important issue concerned by researche-rs.According to the characteristics of hyperchaotic map,this paper used the pseudo-random sequences of the hyperchaotic system to propose and realize a new kind of image survivable storage scheme.This paper proved this scheme was very suitable for software implementation,but also could realize the security and the disater recovery of the image storage.Then did some optimization analysis of this scheme through experiments.
