Data has been working as distinct tool of procuring information. Since the era of 90\u2019s, human being is using data for transmitting or storing information. In the recent past modern technologies are implemented to make a shield and protect data from digital theft or malfunctions. But, even today the sense of insecurity works within us, even for opening an application related our bank account or other security deposits.\u00a0 My principal motive as an Assistant Professor of Computer Science, at The University of Engineering & Management, Jaipur is to flame a light on a technique which is protecting our data system from the past .<\/p>\n

Steganography<\/strong>\u00a0is the method of hiding secret data within a simple, non-secret, file or message in order to avoid exposure; the secret data is then extracted at its destination.<\/p>\n

Let me explain you in very simple words, steganography is the technology which hides your information in another informative object , for example :<\/p>\n

\"\"<\/p>\n

In the above image of Monalisa\u2019s vision is focused and if you see it properly, you can find out the 0,1 sequence in her eyes. Here you can see that one object is a digital image and another object is a binary number. The combination of both develops the concept of\u00a0 steganoraphy. The object can be anything like an audio file, video file, text file or image file.<\/p>\n

Let me throw a light on the background of steganography dated way back in 440 B.C.<\/p>\n

    \n
  1. Wax Tablets: <\/strong>In ancient Greece, people wrote secret messages on wood and then they were covered with Wax.<\/li>\n<\/ol>\n

     <\/p>\n

    2. Shove Heads: <\/strong>This was also used back in ancient Greece. Slaves were hired, their heads were completely shaved and a message was written secretly on their scalp. Following this, the slaves were given time to grow their hair till the message was covered. The slave was then delivered to a recipient who used to shove their heads again to find the message \u00a0.\u00a0 You can see in the image with a written text on the scalp.<\/span><\/p>\n

    \"\"3.I<\/strong>nvisible Ink: <\/strong>Secret messages were written using invisible ink which became visible only when the paper carrying the message was heated. Liquids such as milk, vinegar and fruit juices were used as Invisible inks.<\/span><\/p>\n

    \"\"4.M<\/strong>orse code: <\/strong>Secret messages were written in Morse code on the knitting yarn. A cloth was made out ofthe yarn which was worn by the carrier. For example Jeremiah Denton (<\/span>S. Senator<\/a>representing\u00a0<\/span>Alabama<\/a>\u00a0from 1981 to 1987, a\u00a0<\/span>United States Navy<\/a>\u00a0<\/span>Rear Admiral<\/a>, and\u00a0<\/span>Naval Aviator<\/a>\u00a0<\/span>taken captive<\/a>\u00a0during the\u00a0<\/span>Vietnam War<\/a>. ) blinked his eyes in Morse code to spellthe word \u2015Torture\u2016 in a Television conference. This ensured the US Military that American POWswere tortured in North Vietnam.<\/span><\/p>\n

    \"\"<\/p>\n

    So this is the brief historical journey of Steganography, which has evolved as a tool for maintaining secrecy and value of confidentiality.<\/p>\n
