Abstract
This project implements a steganography tool named HideNQA that will hide text within the GRE’s multiple-choice questions and answers. With HideNQA, confidential information can be smuggled out in an innocuous looking GRE exam. “Noise” here refers to random bits in the covertext that could be modified without discernible change in the quality of the image, audio or video file (covertexts). “Noise” could also mean the traces left behind by a particular steganographic technique. This paradigm was first introduced by Abdelrahman Desoky. Most current steganography algorithms/methods leave some signature or noise in the covertext that can be detected by current steganalysis tools. These algorithms are then vulnerable to analysis and attacks because of these clues left behind. This project will implement a component of Noiseless Steganography, i.e., Nostega called Edustega (short for Educational Steganography) - as described in Desoky’s dissertation.
