Abstract

Steganography is an ancient process used in secrecy and has found new relevance in the modern digital era. In our day-to-day life, we rely on digital media for our personal and professional online communication, the need to protect sensitive information gains paramount importance 1. The threats to hacking of sensitive data in the form of text, image and audio which may lead to heavy financial losses call for innovative and sophisticated methods to ensure encrypted end to end communication, protecting information from unauthorized access. In this regard, the challenge lies in encrypting and decrypting data securely when sending over communication media. Conventional encryption methods may not be full proof to handle new ways of data hacking techniques. Steganography has emerged as a suitable solution which enables the concealment of information which is in the form of image, text, audio and video. Conventional techniques may not fully address the challenges in a wide range of digital communication, necessitating the development of advanced methodologies. A lot of research work has been done in the domain of Security. The LSB Steganography technique has relevant features that collectively enhance its scope and applicability in a wide range of communication. This paper presents enhanced LSB steganography technique to encrypt and decrypt text, image and audio files successfully.
