These probabilities are passed to an entropy decoder and used to decompress
the encrypted message M, creating xβ which is combined with xα to create the
steganogram. Figure 1 illustrates the proposed model-based method for
encoding ...

1.2.3 Steganography A form of cryptography known as steganography is a
technology that embeds a secret text (A) within a non-secret text (B) the carrier to
form a composite text (A + B) known as steganogram. In this case, the
steganogram ...

implements matrix encoding to improve the efficiency of the embedding process,
if the full capacity of the steganogram (modified medium) is unused; matrix
encoding decreases the number of necessary changes. F5 also employs
permutative ...

It can also be used to provide the steganogram with integrity. Another important
benefit is that the lower-level method may be used as a signalling channel to
exchange information that affects the way that the upper-level method functions,
thus ...

It must be emphasized however that if hidden data embedding rate is chosen
reasonably then detecting of the audio watermarking is hard but possible and in
most cases erasing steganogram means great deterioration of voice quality.
