Safe Communication Using Steganography

Abstract

This research aims to propose a method of safe communication using steganography, which involves hiding information in other information to conceal the fact that communication is taking place. Digital images are one of the most popular file formats used for steganography due to their frequency on the internet. The project focuses on hiding secret information within images using steganography techniques. Different techniques have their respective strong and weak points, and their application requirements vary. The proposed technique allows users to choose the bits for replacement instead of using the least significant bit (LSB) replacement from the images. In this technique, the sender selects a cover image with the secret text or text file, hides it in the image, and sends it to the receiver through a private or public communication network. The receiver retrieves the secret text hidden in the stego-image using the software. This method provides a secure and user-friendly interface for individuals to exchange confidential messages. It leverages the power of image steganography to address the growing need for privacy and confidentiality in digital communication. By hiding messages within images, it ensures a covert and secure means of transmitting information while maintaining the visual appearance of harmless images.
