steganography by sid
Stenography is the art of hiding the very presence of communication by embedding secret message into innocuous looking cover document, such as digital image, videos, sound files, and other computer files that contain perceptually irrelevant or redundant information as covers or carriers to hide secret messages. In this paper, a new Least Significant Bit (LSB) nonsequential embedding technique in wave audio files is introduced. To support the immunity of proposed hiding system, and in order to recover some weak aspect inherent with the pure implementation of stego-systems, some auxiliary processes were suggested and investigated including the use of hidden text jumping process and stream ciphering algorithm. Besides, the suggested system used self crypto-hiding pseudo random key generator. The auto-key generator has purposes to investigate the encryption and embedding processes .The hiding results shows no noise in the stego-wave file after embedding process, also no difference in size is found between the original wave audio file and stego-wave file. Keywords: Audio steganography, Text hiding, (LSB) technique. 1. Introduction Steganography, from the Greek, means covered, or secret writing, and is a long-practiced form of hiding information. Although related to cryptography, they are not the same. Steganography's intent is to hide the existence of the message, while cryptography scrambles a message so that it cannot be understood. Steganography includes a vast array of techniques for hiding messages in a variety of media. Among these methods are invisible inks, microdots, digital signatures, covert channels and spread-spectrum communications. Today, thanks to modern technology, steganography is used on text, images, sound, signals, and more [1]. Cryptography is the study of mathematical techniques related to aspects of information security such as confidentiality, data integrity, entity authentication, and data origin authentication [2]. This paper introduces a new steganography system based on LSB technique using non- compressed wave audio file. The embedding text can be enciphered then embedded using the same bytes. Of the wave file, as an encryption and hiding keys, of course the two used bytes are different from each others to increase the complexity of the hiding algorithm. The hiding results show no noise that can be heard in the stego-wave file after embedding process. The proposed steganography system was chosen because the wave files is common in used in all communication means like, internet, mobiles, computers etc. Since the wave file has huge data, it is considered a good container of a big message. When random LSB technique is used, it will be hard to detect or broken. The proposed hiding algorithm can be considered a simple idea for encryption and hiding, but not the best efficient method for hiding.
