Journal ArticleDOI
Comparative study of digital audio steganography techniques
TL;DR: Current digital audio steganographic techniques are reviewed and evaluated based on robustness, security and hiding capacity indicators and a robustness-based classification of steganography models depending on their occurrence in the embedding process is provided.
Proceedings ArticleDOI
A view on latest audio steganography techniques
TL;DR: A current state of art literature in digital audio steganographic techniques is presented and their potentials and limitations to ensure secure communication are explored.
Journal ArticleDOI
Unified phase and magnitude speech spectra data hiding algorithm
TL;DR: Objective results show that the presented algorithm secures hidden data and achieves interesting tradeoffs between the hiding capacity and the speech quality.
Proceedings ArticleDOI
Dynamic energy based text-in-speech spectrum hiding using speech masking properties
TL;DR: The objective and subjective evaluations show that introducing the energy-based frequency masking opens new frontiers in text-in-speech steganography since higher bit rate text embedding was achieved while obtaining a stego-speech with unnoticeable distortion.
Proceedings ArticleDOI
Controlled Distortion for High Capacity Data-in-Speech Spectrum Steganography
TL;DR: This paper presents a technique that limits the impact of high data capacity embedding on the quality of stego wideband speech by using the energy of each frequency bin component to determine the maximum number of bits that can be confined without inducing any noticeable distortion on the cover speech.
