DST approach to enhance audio quality on lost audio packet steganography
Lost audio packet steganography (LACK) is a steganography technique established on the VoIP network. LACK provides a high-capacity covert channel over VoIP network by artificially delaying and dropping a number of packets in use to convey stegnogram. However, the increasing loss of packets will hurt the quality of the VoIP service. The quality deterioration will not only affect the legitimate V...
متن کاملOn steganography in lost audio packets
This paper presents a new hidden data insertion procedure based on the estimated probability of the remaining time of the call for the steganographic method called lost audio packets (LACK) steganography. LACK provides hidden communication for real-time services such as voice over IP. The analytical results presented in this paper concern the influence of LACK’s hidden data insertion procedures...
متن کاملLost audio packets steganography: the first practical evaluation
This paper presents first experimental results for an IP telephonybased steganographic method called LACK (Lost Audio PaCKets steganography). This method utilizes the fact that in typical multimedia communication protocols like RTP (Real-Time Transport Protocol), excessively delayed packets are not used for the reconstruction of transmitted data at the receiver, i.e. these packets are considere...
متن کاملGenetic Audio Steganography
A wide range of steganography techniques has been described in this paper. Beside the evaluation of embedding parameters for the existing techniques, two problems -weaknessesof substitution techniques are investigated which if they could be solved, the large capacity strengthof substitution techniques would be practical. Furthermore, a novel, principled approach to resolve the problems is prese...
متن کاملAudio Quality Assessment in Packet Switched Networks
Transmitting digital audio signals in real-time over packet switched networks (e.g., the Internet) has set forth the need for developing signal processing algorithms that objectively evaluate audio quality. So far, the best way to assess audio quality are subjective listening tests, the most commonly used being the Mean Opinion Score (MOS) recommended by the International Telecommunication Unio...
