STEGANOGRAPHY
AND VARIOUS
METHODS OF
DECIPHERMENT
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.
