              INTRODUCTION



              Steganography, also known as secret writing, refers to any written information

              technique done by a spy to conceal the real text, which can be decoded by using
              different materials.
              Steganography is the Greek word in which ‘Steganos’ means covered or hidden

              and ‘Graphein’ means to write. Secret writing cannot be seen with the naked
              eye, but it can be revealed through various methods, such as keeping it under

              appropriate light, applying heat to the writing, and spraying specific chemicals
              onto the writing.
              Invisible inks are used to do secret writing, these writings are done using various

              inks such as vinegar, lime juice, saliva, sweat, etc., These solutions absorb the
              paper, and the writings made through them turn transparent in colour.

              Invisible  inks  can  be  categorised  into  three  types:  writings,  which  can  be
              deciphered by heat mechanisms, chemicals, and ultraviolet rays.
