The Application of Audio Steganography for Network Multimedia
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.
