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。
Steganography is a covert communication technology. The purpose of steganography is to avoid doubting the transmission of the hidden message. The basic principles of steganographic system and steganalysis are analyzed, and a new steganographic vector, error correction coding, is proposed. A steganographic system based on error correction code was established. A new steganography algorithm based on linear block codes was proposed and its reliability and security were analyzed.
