Introducing Image Steganography in Bangla Language Communication

Abstract

Steganography is a modern technique of science by which any message can be hidden in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message like a form of security through obscurity. This technique has advantage over cryptography alone, is that messages do not attract attention to themselves where cryptography protects the contents of a message, steganography can be said to protect both messages and communicating parties. Now-a-days wide ranges of algorithms have been used using text, audio, video and images files as covering media. This paper represents a new approach for steganography in bangla texts considering the typical structure of bangla alphabets and also introduces a much easier process by which secret message is embedded in a 24 bit color image by using widely used 4LSB method. This paper shows a new path to provide an imperceptible stegoimage for human natural vision by enhancing the embedding capacity of image steganography.
