STEGO HIDER

ABSTRACT

Steganography is the art  of hiding information. There are a large number of Steganographic methods used in different applications. It is extensively used in Digital Water marking, communication within closed community with additional degrees of security. An attempt is being made to implement a new technique , entitled “Steganographic Application Tool”, for image encoding in steganography. It provides more security for data transfer on Internet and other networks. Our intention is to hide the existence of the message; While Cryptography scrambles a message so that it can not be understood.

                  Using Steganography a secret message can be transmitted without the fact of the transmission being discovered. This hiding of data can be done in three different media such as text, image and audio files. Though there are variety of image formats to implement the algorithms used in this system, we use the JPEG format to embed the Plain text as it contains the compressed image format. In this technique, firstly the pixels values (RGBvalues) of the image in which the plain text is to be embedded are extracted. The bits of the plain text into the two LSB bits of the RGBvalues in the image. The transparency bits of the pixels are not disturbed. The fact that we are embedding the plain text into the two LSB bits enables the recipient to get the original image without any distortions. In order to provide more security, we are first encrypting the message using DES algorithm and then cipher text as the input to our technique and the same message will be extracted and decrypted at the receiver end.

 Steganography is really interesting subject and the applications using Steganography are increasing day-by-day. A number of algorithms were developed and implemented to achieve Steganography in images and audio. Many new algorithms are coming and each of them uses a unique method of making life of a Steg-Analyst more miserable everyday.
