Communications and information
technology is rapidly grows and provides a
major influence on people's lives. The rapid
development of information technology is
currently supported by the importance of the
need for information. It can be seen from the
development of today's internet network is
rapidly increasing. Informations that
transmitted is not meant for everyone. Along
with the development of these technologies,
security threats becomes more and more
powerful, particularly for the undisclosed
information. Various threats in cyberspace such
as hacker, cracker, carder makes people worry
about the security of the information they sends.
This concern that make the development of
information hiding techniques. One of the well
known information hiding technique is
steganography. In general, steganography
means a technique and art of hiding a fact to
communicate. By using steganography, secret
message can be inserted into an unsuspicious
information and send it without being aware of
the existence of the secret message. There are
several criteria that must be considered in
steganography is fidelity, robustness, and
recovery. Fidelity means that stegomedium
quality has not changed much due to the
insertion. The changes can not be perceived by
the senses.
