WHAT IS MEANT BY STEGANOGRAPHY?

   

     

             In past few years, steganography term attracted attention of law enforcement agencies. This technique was used by hackers to transmit their secret message to other terrorists. Hackers used steganography in 9/11 attack too. So, if you are interested in computer security, you must know about Steganography. In this article, we will cover what is Steganography and tools available for this.

Steganography

        Steganography is the art of hiding a secret message behind the normal message. This is used to transfer some secret message to other person and no interim person will be able to know what the real message which you wanted to convey was. This art of hiding secret messages has been used for years in real life communications. Since the evolvement of digital communication, it has also been used in digital 

conversations. In computer, it is achieved by replacing the unused or useless data of a regular computer file with the bit of your secret message. This secret hidden information can be a plain text message, cipher text, or image. One can hide information in any kind of file. Usually image, video and audio files are used to hide plain text message or image message. Few tools now allow one to hide files inside an image or audio file.

The main reason for using steganography is that you are hiding your secret message behind an ordinary file. No-one will suspect the file. People will generally think it as an ordinary file and your secret message will go without any suspicion. The file used to hide a message will function normally and you will not suspect just by looking the file. There are various conditions when there is the need of secure transmission of files. Hackers are everywhere and always try to intercept communication to get confidential data. By using Steganography, we can reduce the chance of data leakage. Even if the attacker gets access to your account or email, he will have no clue where is the confidential file in your account.

There are various ways of achieving the steganography in digital communication. However, you do not need to perform coding to achieve this. There are various software tools are available for Steganography. This software can hide your secret message behind the image file, HTML fil, DOC file e or any other kind of file.
