Design and evaluation of steganography for voice-over-IP

—According to former results from [1] 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 [1], [13], [15] and [16]. 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.
