Enhancing Data Security: Employing Finite State Machines in a Steganography Encryption Scheme

Abstract

Steganography is an intricate technique used for concealing confidential information within diverse types of media. Both Steganography and cryptography aim to protect data, with a key distinction lying in the processed output's appearance. Cryptography transforms the output into a scrambled format, rendering it challenging to decipher without the appropriate key. In contrast, Steganography ensures that the concealed data remains imperceptible, seamlessly blending into the cover medium without any observable changes. Within the domain of computer science, automata theory assumes a crucial role, exploring the study of abstract computing devices or machines. This field holds significance as it furnishes a theoretical framework for comprehending and modeling systems with finite states. Finite state systems are prevalent in computer science, and the theory of finite state systems emerges as a valuable design tool for crafting efficient and resilient systems. By applying concepts from automata theory, engineers and researchers can scrutinize, design, and implement intricate systems with finite states, thereby contributing to advancements in diverse computing applications. In this paper, we present a pioneering technique for concealing data streams through the utilization of finite state machines. Furthermore, the paper systematically analyzes and evaluates the effectiveness of the proposed method
