Abstract

Steganography is a practice of concealing or hiding secret information within a non secret multimedia to avoid detection. It can also be described as hiding information in plain sight. The word steganography comes from greek words “steganos” which means to hide or to be hidden and “graph” which means to write or embed. Steganography mainly deals with hiding sensitive information into multimedia to avoid detection, but this can be used alongside with encryption to make it even more secure during transmission of the multimedia. This paper presents a web application that enables the user to perform steganography on image, audio and video along with a strong encryption for the secret text message that is going to be embedded in the multimedia. This research is carried out so that the said web application can be developed and lets the user share sensitive information without worrying about the information getting stolen by an attacker and also this research can be improved further as every module is encapsulated and implemented as importable libraries.
