中文摘要: 以压缩格式的多媒体作品为掩蔽载体的隐写技术,其性能的优劣受限于对载体冗余空间的挖掘是否充分以及对载体原始统计特性保持的程度。本课题拟以压缩与隐写两种操作之间的相互制约关系为切入点,构建适用于MP3音频这一掩蔽载体的交叉域隐写框架,研究如何保持秘密信息稳健性以及如何提高隐写算法抗统计检测能力的策略和方法。研究旨在克服压缩与隐写之间的相互影响,在不同数据域实现对载体冗余空间的挖掘,并利用纠错编码、闭环策略和模型隐写等方法,发展一类可操作性强、安全性高的MP3音频隐写方法和技术。研究成果有望弥补现有MP3音频隐写方法在安全性方面所存在的不足,同时也可为保密通信系统的实现提供新的方法与途径。

英文摘要: The performance of the steganographic techniques for compression multimedia works is limited by the exploiture of the redundant space and the preservation of the statistical properties. Taken the mutual constraint relation between compression and steganography as a starting point, the proposed project is intended to construct a cross-domain steganographic framework for MP3 audio. Based on the framework, the stability of the secret message and the capability of anti-statistical detection will be the main research contents. The aim of the project is to overcome the interference between compression and steganography. We will exploit the redundant space of the carrier in different domain, and develop a class steganographic methods with practicability and high security by ultilizing error correction coding, closed-loop strategy and mode steganographic mechanism. The research is expected to make up for the shortcomings of the existing MP3 audio steganography and provide novel approaches for secure covert communication system.
