New Approach in Steganography Algorithm by Using Audio and Image as Secure Information Based on Chaotic Method

In the modern era of digital communication, safeguarding sensitive information has become a critical concern due to increasing cyber threats and unauthorized data breaches.Two foundational techniques widely employed to enhance data security are steganography and cryptography.Cryptography transforms information into an unreadable format, securing it from unauthorized access but often signaling the presence of valuable data.Steganography, on the other hand, ensures that sensitive data is invisible to attackers by hiding the information's mere existence.A better level of security can be attained by combining these two methods.This study presents a new chaotic-based steganography technique in which images are used as the main information-hiding medium.Additionally, for the first time, a novel combination of audio and image as hidden data is suggested.Confidential information is better protected by this two-layered approach, which makes it more resistant to illegal eavesdropping and hacking attempts.Strong security is ensured by the suggested system's use of a high-precision chaotic map for encryption.With a Mean Squared Error (MSE) of 0.083 and a Peak Signal-to-Noise Ratio (PSNR) of 74.87, the simulation results demonstrate the algorithm's efficacy.These measurements attest to the algorithm's capacity to preserve data integrity while offering a high degree of imperceptibility, which qualifies it for real-world use in secure communication.
