Abstract

A METHOD TO HIDE SECRET DATA IN COVER TEXT IS DESCRIBED. SECRET DATA IS ENCODED INTO BASE64 STRING. NEXT, THE COVER TEXT LENGTH IS DETERMINED (42) TO DETERMINE MINIMUM CAPACITY OF WHITE SPACES REQUIRED TO ACCOMMODATE SECRET DATA. LATER, DATA IS CONVERTED INTO BITS (44). THE BITS ARE HIDDEN INTO COVER TEXT (46) WHEREIN BIT VALUE OF 0 IS REPRESENTED WITH SINGLE SPACE BETWEEN TEXT AND BIT VALUE OF 1 IS REPRESENTED WITH DOUBLE SPACE BETWEEN TEXT TO FORM A STEGO-TEXT (22).
