Text, Image and Audio Steganography

Abstract

Abstract: Steganography refers to the concealment of confidential data within a common medium, like a text, image, or audio file, without altering its original appearance, to evade detection. This method is used for several purposes, including protecting data privacy, preventing unauthorized access to data, and ensuring safe information transmission over insecure networks. While steganography can be used for legitimate purposes such as by military, law enforcement, and journalism, it can also be employed for malicious activities like cybercrime and terrorism. The least significant bit (LSB) of each letter in text & audio and the LSB of each pixel in images are altered in steganography to make the alterations invisible. Advanced steganography algorithms like Masking & Filtering and Encrypt & Scatter have improved security against steganalysis assaults while producing higher-quality stego images. The method’s capability for concealing text with an unlimited hidden text size in text, audio, and images will be employed in the outcome.
