Protection of Executables Employing a NovelDual StageDigital Data Hiding Scheme

H S Jayaramu, Arvind K Gautham

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. Keywords: Image Steganography, Audio Steganography, Discrete Wavelet Transform, Spectrum Analysis
