Whispers in the Pixels: Exploring the Efficacy and Invisibility of LSB-Based Steganography

Amid the surge of instantaneous digital communication, the security and privacy of private data have escalated quickly. Despite being constructive, the conventional encryption methods provide an evident indication that information has been secured. This paper discusses the implementation of Least Significant Bit (LSB) steganography, allowing information to be subtly hidden inside digital images without losing discernable quality when viewed. The system consists of a lightweight web-based application built in Python using a Flask backend and ReactJS frontend. The application provides a seamless experience for users to embed and extract hidden messages. The application was developed to accept a user variable text message and a PNG image, where the message would be hidden in the least significant bits of the image’s pixels.
