【摘要】 隐写术是一种隐蔽通信技术。隐写术的目的是避免对传送被隐藏消息的行为产生怀疑。分析了隐写系统和隐写分析的基本原理,提出了一种新的隐写载体—纠错编码。建立了一个基于纠错码的隐写系统,提出了一个新的基于线性分组码的隐写算法,并分析了它的可靠性和安全性。更多还原

【Abstract】 Steganography is the technology of c overt communications.The goal of steganography is to avoid drawing susp icion to the transmission of a hidden message.In this paper,basic principle of steganographic systems was analyzed,then a new steganographic cover -error -correction code was pr esented.A model of steganographic s ystem based on error -correction cod e was built.A new steganographic arithmetic which is based on linear block coding was presented and it’ s reliability and security was analy zed.更多还原
