Steganography is an ancient art that encompasses various techniques of information hiding, the aim of which is to embed secret information into a carrier message. Steganographic methods are usually aimed at hiding the very existence of the communication. Due to the rise in popularity of IP telephony, together with the large volume of data and variety of protocols involved, it is currently attracting the attention of the research community as a perfect carrier for steganographic purposes. This paper is a first survey of the existing VoIP steganography methods and their countermeasures. include circumvention of web censorship and surveillance, computer/network forensics, or copyright protection. Techniques can be used with VoIP to improve its resistance to packet losses and improve voice quality [Aoki 2003;2004], extend communication bandwidth [Aoki 2007] or provide means for secure cryptographic key distribution [Huang et al. 2011a].The expansion of TCP/IP networks opened up many possibilities for covert communication due to changes in the traditional circuit-switched networks paradigm; services/applications are created by the network users rather than by the network itself, the transport and control functions are not separated and can be

“…Additionally, an additional control protocol in a hidden channel can be applied to provide increased reliability (it is sometimes called a microprotocol). One solution is to use an approach proposed by Hamdaqa and Tahvildari [8], as it can be easily incorporated into the proposed method. It provides a reliable and fault-tolerant mechanism based on a modified (k, n) threshold of a Lagrange Interpolation, and the results demonstrated by that paper prove that the complexity of the steganalysis is increased.…”

In this paper a new information hiding method for Skype videoconference calls -YouSkyde -is introduced. A Skype traffic analysis revealed that introducing intentional losses into the Skype video traffic stream to provide the means for clandestine communication is the most favourable solution. A YouSkyde proof-ofconcept implementation was carried out and its experimental evaluation is presented. The results obtained prove that the proposed method is feasible and offer a steganographic bandwidth as high as 0.93 kbps, while introducing negligible distortions into transmission quality and providing high undetectability.

“…It considers the signal processing vulnerabilities of substitution technique based spatial steganography [12] and establishes its resilience towards them. It also responses positively to the lagrange's interpolation [14] based steganalysis The algorithm considers the effective steganalysis methods of estimating secret key in sequential embedding methods through low, medium, and high signal-to-noise ratio (SNR) analysis and abrupt change detection based steganalysis [13]. The abrupt change detection using sequential probability ratio test (SPRT) has also been applied against this algorithm as shows inarguably positive statistics.…”

Abstract.We have explored a new dimension in image steganography and propose a deft method for image-secret data -keyword (steg key) based sampling, encryption and embedding the former with a variable bit retrieval function. The keen association of the image, secret data and steg key, varied with a pixel dependant embedding results in a highly secure, reliable L.S.B. substitution. Meticulous statistical analyses have been provided to emphasize the strong immunity of the algorithm to the various steganalysis methods in the later sections of the paper.
