Abstract: | The use of contemporary devices such as
android, blackberry and other smartphones is
as a result of an improvement of technologies
in communication over the period. As a result
of this, there are several security concerns
which keep coming up because the
mechanisms in place to ensure, that data and
information are protected is inadequate. Many
have tried using either cryptography or
steganography. Others have tried combining
the two which is the best but have failed to use
the optimum methods of both cryptography
and steganography. Fortunately, this work
combines the use of the best techniques under
both steganography and cryptography to come
up with a system that is more robust, hence
resistible to attacks. The act of converting a
message or an information into a non-readable
file format so that a third party or an intruder,
either than the intended recipient will not
know the content of the message is known as
cryptography. Steganography also deals with
the act of hiding a message from the view of
an unauthorized person in a cover object. This
work employs an optimum steganography and
cryptography. The Least Significant Bit (LSB)
algorithm is used to insert or embed a message
into a cover object. The cryptography used
under this study employs the use of the
asymmetric cryptography known as the RSA.
The combination of both the LSB insertion
technique and the RSA technique for use by
the proposed system makes it one of the best
applications to ensure data security and
secrecy on android smart devices It can be realized that the security and strength
of the proposed system for use by smartphones
lies in the combination of cryptography and
steganography. One fascinating thing about the
proposed system is that unlike the other
existing steganographic systems which is
unable to accept different image file types, the
proposed system is able to do so. |
