A secure audio steganography approach
2009 International Conference for Internet Technology and Secured Transactions, (ICITST), 2009A wide range of steganography techniques has been described in this paper. Beside the evaluation of embedding parameters for the existing techniques, two problems -weaknesses- of substitution techniques are investigated which if they could be solved, the large capacity - strength- of substitution techniques would be practical.

Multi agent based audio steganography
2015 IEEE International Conference on Computational Intelligence and Computing Research (ICCIC), 2015Today's Information Technology grows rapidly with new technologies and need more security for the data transmission over the internet. Steganography is one of the solutions to ensure the data secure over the internet. An audio steganography is a method to transfer concealed information by changing the cover audio file without degrading the quality of ...

Lossless Adaptive Digital Audio Steganography
Conference Record of the Thirty-Ninth Asilomar Conference onSignals, Systems and Computers, 2005., 2006This paper presents a lossless adaptive digital audio steganographic technique based on reversible two and higher dimensional integer transform. The adaptive technique is used to choose the best blocks for embedding perceptually inaudible stego information, and to select the best block sizes to maximize the number of blocks/capacity.

Supraliminal Audio Steganography: Audio Files Tricking Audiophiles
2009A supraliminal channel is one in which the secret message is encoded in the semantic content of a cover object, and that is robust against an active warden. Such channels frequently have a very low embedding rate and therefore are unsuitable for more than simply exchanging steganographic public keys.

Audio Steganography Using Spectrum Manipulation
2011This paper describes a method for achieving audio steganography through spectrum modification of the cover signal- the signal into which the useful and valuable information is embedded. The embedded data signal is inserted into the regions of the cover signal spectrum where power of frequency content is low.

Audio steganography using bit modification
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003A method of embedding a covert audio message in a cover utterance for secure communication is presented. The covert message is represented in a compressed form with possibly encryption and/or encoding for added security. One bit in each of the samples of a given cover utterance is altered in accordance with the data bits and a key. The same key is used

High Data Rate Audio Steganography
2019Steganography is an art to hide information without affecting perceptual transparency of digital media files. Media files include audio, video, image, text, software and so on. Hiding information is required for secure transmission of data. In general, media files are known as cover file which wrap the data to be transmitted.

Robust multi layer audio steganography
2015 Annual IEEE India Conference (INDICON), 2015In this paper a robust audio steganography method is introduced which involves multiple layers for embedding secret data. In LSB technique generally a single or multiple bits are embedded always in one or some particular bit positions. So it is easy to get that data by knowing those positions.

Audio-to-image wavelet transform based audio steganography
47th International Symposium ELMAR, 2005., 2005In this paper, we propose an audio steganographic scheme based on wavelet audio-to-image transform. The scheme converts the audio steganographic issue into well-explored image steganographic one. In the scheme, the host audio signal is transformed into image, the covert data are embedded in the image by an image steganographic scheme and finally, the ...
