This research work defines the various techniques used for
information hiding, their applications and also discusses the
drawbacks of implementing those techniques independently. The
motivation for this work includes provision of protection of
information during transmission without any detection of
information. In the present work, it has been observed that
steganography is the solution for given problem as in this
technique, existence of data is not evident. Among various types of
steganographic techniques, image steganography is best solution.
Thus, a new image steganography scheme based on Effective Channel
Selection Technique for Encoding and Decoding of Data has been
proposed. The proposed scheme can encode any colored image files as
well as gray-scale image files in order to protect confidential
text data from unauthorized access. A PSNR calculator tool has been
used for measuring the image quality factors. Further, these
quality parameters have been used to generate graphical outputs and
tabular values for comparison with the best known image
steganographic techniques.
