Multimedia Multilevel Security by Integrating Steganography and Cryptography Techniques

Abstract

Multimedia-based Steganography is famous for its security purpose, These steganography techniques were used by our ancestors and it is still carried out now with better and vast technology. The aim is to provide better security in an effective and secure manner where the original data is covered and hidden by some of the media covers like video, audio, image, text, etc. so that only the sender who sends it and the receiver who receives it can only see the secret data inside it. In this project, we are combining all the steganography types and giving the user the advantage of selecting his/her own choice of multimedia cover to hide the real content. The options of the different algorithms will be provided so that the users who are comfortable with that algorithm have the privilege to select it and the file will be processed with that algorithm. This steganography technique is used by the government to send information that supports national security, The company uses it for digital copyrighted media, and military services also use this technology to send it to the army who are on a mission. We aim to provide the same with more security and a rich user experience. In this survey, a variety of methods is used to provide the same facility and recent research in the field.
