This paper presents a novel algorithm of hiding
secret messages by applying mathematical lemmas and
information theory. The proposed algorithm can hide more
information with acceptable embedded rate and achieves
requirements of information hiding algorithm and simply
information extracting. The main idea is applying modern
algebra to solve the information hiding problem in multimedia.
In order to prevent some attacks on stganography, hidden
initial bits of image data pixels are chosen randomly. The
extracted information are achieved without the reference of the
original image and extracted keys. The experiment results
show that our approach is effective and reliable.
