Steganographic Method with Code Control of Information Embedding Based on Multi-level Code Words

Abstract

Effective steganographic methods are an integral part of modern information security systems. At the same time, one of the key requirements for modern steganographic methods, taking into account their needed implementation on mobile and IoT devices, is their low resource consumption maintaining high perception reliability, throughput, and resistance to attacks against the embedded message. The steganographic method with code control of additional information embedding using multi-level code words is presented in this work. A new synthesis approach of multi-level code words with a high selectivity coefficient is developed. It allows us to ensure the specified properties of steganographic messages. Sets of multi-level code words of practically valuable sizes are synthesized and studied. Experimental studies of the effectiveness of the steganographic method with embedding code control based on the presented multi-level code words are conducted. They ensure a high level of its resistance to attacks against the embedded message, by compression, noise superimposing, and blurring, while ensuring sufficient bandwidth and perception reliability in practice.
