Enhancing Image Steganography with Hybrid PSO-GSA Optimization Technology

Problem Definition

Image steganography is a pivotal aspect of secure data communication, ensuring the concealment of data within an image to prevent unauthorized access. However, the selection of the optimal region and pixel within the image for data hiding remains a significant challenge. The need to identify a pixel that minimizes errors and maximizes peak signal-to-noise ratio (PSNR) is crucial for maintaining the integrity and security of the hidden data. Existing methods often lack precision and efficiency, leading to compromised data security. As a result, there is a pressing demand for a more accurate and effective approach to securely hide data within images, highlighting the necessity of developing a robust solution to address these limitations and pain points in image steganography.

Objective

The objective is to develop a more precise and efficient method for securely hiding data within images using a hybrid of Particle Swarm Optimization (PSO) and Gravitational Search Algorithm (GSA) in MATLAB. This approach aims to identify the optimal region and pixel within an image to enhance data hiding efficiency, accuracy, and security while maximizing peak signal-to-noise ratio (PSNR) and minimizing errors. By automating the process of selecting areas with low errors and high PSNR, the project seeks to provide a comprehensive and robust solution for secure data embedding in images. Through monitoring key metrics and comparing the proposed method against other algorithms, the goal is to advance the field of image steganography and offer a reliable approach for securing data within images.
