面向网络多媒体的音频隐写术应用

The Application of Audio Steganography for Network Multimedia

音频隐写术利用音频信号的冗余性和人类听觉系统的特性,将秘密信息嵌入音频中进行隐蔽传输。根据不同的嵌入方式,音频隐写术可分为时域隐写术、频域隐写术和扩频隐写术等。不同的音频隐写术各具特点,并适用于不同场景。在网络多媒体环境中,音频隐写术在版权保护、身份验证及军事通信等领域发挥重要作用,但也面临着嵌入容量与健壮性、实时性与安全性之间的平衡等挑战。基于此,文章深入探讨音频隐写术的原理、特点、分类以及在网络多媒体环境中的应用,展望其在未来信息安全领域的发展前景。

Audio steganography makes use of the redundancy of audio signals and the characteristics of human hearing system to embed secret information in audio for covert transmission.According to different embedding methods,audio steganography can be divided into time domain steganography,frequency domain steganography and spread spectrum steganography,which have their own characteristics and are suitable for different scenes.In the network multimedia environment,audio steganography plays an important role in the fields of copyright protection,identity authentication and military communications,but it also faces challenges such as the balance between embedding capacity and robustness,real-time and security.Based on this,this paper discusses the principle,characteristics,classification of audio steganography and its application in the network multimedia environment,and looks forward to its future development in the field of information security.
