Critical analysis of security in voice hiding techniques

This paper provides a comparative assessment of detection in certain voice hiding techniques. The assessment is based on the complexity of breaking the stego key, the robustness of the hiding techniques, and the stego transmission rate. Unlike cryptography, to break the stego key in voice communication requires not only an extensive search but also estimation techniques for determining the values of parameters used in data embedding. We also consider disturbing embedded data in case resource constraints are imposed.
