Design and evaluation of steganography for voice-over-IP
Christian Krätzer, Jana Dittmann, Thomas Vogel, Reyk Hillert · 2006
According to former results from (Dittmann et al., 2005) in this paper we summarize the design principles from the general approach and introduce extended experimental test results of a voice-over-IP (VoIP) framework including a steganographic channel based on (Dittmann et al., 2005), (Dittmann and Hesse, 2004), (Kraetzer et al., 2006) and (Vogel et al., 2006). We show that using this framework it is largely secure to transmit hidden messages during a VoIP session and demonstrate results with respect to perceptibility for music and speech data
