Steganography is the practice of concealing information within another medium to ensure secure communication without raising suspicion.Unlike cryptography, which focuses on encrypting data to make it unreadable, steganography aims to hide the existence of the message itself.This technique has been employed throughout history, from ancient civilizations using invisible inks to modern digital applications involving multimedia files such as images, audio, and video.In the digital era, steganography has gained significant importance due to increasing concerns over data privacy and cybersecurity.Various steganographic techniques exist, including spatial domain methods (e.g., Least Significant Bit (LSB) substitution), transform domain techniques (e.g., Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT)), and adaptive steganography, which intelligently hides data based on image content.These techniques differ in terms of robustness, payload capacity, and imperceptibility.This project's Sustainable Development Goal is to promote the creation of cutting-edge AI/ML technologies for data protection and digital forensics and Quality Education by promoting awareness and understanding of cybersecurity and data protection.
