Abstract: Digital steganography provides efficient means
of hiding digital data behind a digital cover like image video or
audio as noise or redundant data. One of the important
requirement of most steganography technique is that cover
data must be significantly larger than the payload to efficiently
distribute the redundant information over large data. This
ensure better security and becomes challenging in identifying
or cracking the Stegano object. Due to aforementioned reason
steganography has been predominantly used in text payload.In
this work we propose a unique dual stage steganography
technique to hide Exe files by first embedding them behind a
2D image file followed by embedding the image in an audio
cover. As EXE files are more sensitive to errors and even a
single bit error may cause the application to crash, the method
needs more accuracy. Also as EXEs are of larger size than
normal text, they present significant challenge in ensuring that
payload can not be traced in the stego object. To provide
application exes better security we use 2D-1D steganography
by combining image and audio steganography
technique.Results show that for first stage for a PSNR over
50db and produce significantly acceptable result of 45db for
2e-3 BPP.
