Abstract:
This paper managed to propose
robust audio data hiding through
optimization-based problem transformation
method, Probabilistic Global Search
Lausanne Algorithm (PGSL) in modified
discrete cosine transform (MDCT) domain.
We manipulate the MDCT coefficients in the
selected frames with the stego key and, then
implement the optimal best points searching
process through PGSL Algorithm to obtain the
best secret audio message embedding
positions. The Lowest Bit Error Rate value are
defined the optimal best coefficients. The
inverse modified discrete cosine transform
(IMDCT) is applied to form stego audio. In
our audio data hiding scheme, the results of
imperceptible (audible difference) between the
stego and cover audio will be evaluated using
Spectrogram and Informal Listening Tests.
The robustness will be tested with standard
digital signal manipulation attacks as Noise
addition, MPEG compression and
Resampling. The goal of proposed data hiding
is to protect the privacy of secret audio
message from unauthorized accesses, and to
satisfy audio steganography issues as
imperceptible, embedding capacity and robustness
