Steganographic Techniques for High-Capacity Covert Communication in Images and Videos

Abstract

Steganography is the art of concealing information within other data to obscure the transmission process. Digital photos are the preferred carrier files due to their ubiquity online. Various steganography techniques exist for hiding sensitive data in video frames, each with distinct strengths and weaknesses. Some applications require total invisibility for critical information, while others can accommodate larger secret messages. Our project conceals messages within visuals, enabling users to select replacement bits instead of employing less secure LSB substitution. Data transmission, the process of sending data from source to destination, often involves slower mediums like coaxial cables and twisted pair wires, which can result in data leaks or losses. To address these issues, fiber optics are employed. Fiber optics transmited data as light beams, minimizing data leakage and incorporating security measures. In our proposed system, we enhance fiber optic encryption through the use of images.
