A New System for Hiding Data within (Unused Area Two + Image Page) of Portable Executable File Using Statistical Technique and Advance Encryption Standared

Abstract

The internet and the World Wide Web have revolutionalized the way in which digital data is distributed. The widespread and easy access to multimedia content has motivated development of technologies for steganography or data hiding, so the strength of the combination between hiding and encryption science is due to the non-existence of standard algorithms to be used in hiding and encrypting secret messages. Also there are many ways in hiding methods such as combining several media (covers) with different methods to pass a secret message. Furthermore, there is no formal method to be followed to discover a hidden data. For this reason, the task of this paper becomes difficult. In this paper proposed a new system of information hiding using computation between cryptography and steganography is presented. The proposed system aim to hide information (data file) using computation between cryptography and steganography with in computation area which is unused area two and image page of any execution file (exe.file), to increase the degree of security and the amount of hidden data within exe file without change the size of cover file, to make sure changes made to the exe.file will not be detected by anti-virus and the functionality of the exe.file is still functioning. The system includes two main functions; first is the hiding of the information in the with in computation area which is unused area two and image page of PE-file (exe.file), through the execution of four process (specify the cover file, specify the information file, encryption of the information, and hiding the information) and the second function is the extraction of the hiding information through three process (specify the steno file, extract the information, and decryption of the information). The proposed system is implemented by using Java.
