Semantic Mimicking: Creating Nonsense with Sense

Krista Bennett - Purdue University

Nov 05, 2003

Abstract

Steganography is an ancient art. With the advent of computers, however, we have more accessible bodies of data in which to hide information, and increasingly sophisticated techniques with which to analyze and recover that information. While much of the recent research in steganography has been centered on hiding data in images, many of the solutions that work for images become more complicated when applied to natural language text as a cover medium.



Many approaches to steganalysis attempt to detect statistical anomalies in cover data which predict the presence of hidden information. Peter Wayner
