Image Steganography for Hidden Communication

Abstract

Modern steganographic methods, which conceal the existence of communication, are needed to exploit contemporary modes of information exchange. Measures of performance for these methods are essential to compare specific algorithms and determine appropriate uses. This report develops a methodology for steganographic data hiding. The methodology encompasses derivation of a general theory of steganographic communication, including theoretical capacity hounds, and design of an actual data-hiding technique that used digital imagery as a cover. The technique promotes maximization of payload, allows error-free recovery of embedded date, and provides some resilience to removal while concealing the existence of the embedded information from the observer and the observer's resources (e.g., computer).
