Xiaoyan Hu, Lejun Zhang, Tianwen Huang, Xiaoying Lei · 2018
Ensuring the security of a communication system is the key step of information hiding. With the rapid development of Internet technology and the increasingly complex network environment, more and more secret information needs to be transmitted over the network. Voice over IP (VoIP) is based on the IP network of digital transmission technology, taking voice services in VoIP as a steganographic carrier is one of the important methods for secure transmission of secret information. In this paper, we will start with the communication principle of VoIP streaming media information hiding, and gives the definition of imperceptibility, undetectability, irreducibility, unattackable, and insensitivity of VoIP streaming information hiding, and then analyze the covert communication process of steganography for VoIP. Finally, a security evaluation method based on information hiding of VoIP streaming media is proposed.
