Android Application for Image Steganography using Android Studio

Abstract

Abstract: Image Steganography is mainly used for hiding an image or secret message in a cover image. For data hiding, this technique is being widely used for so many years. Image steganography is being used now by government, individual sender and receiver, in business and in so many fields. Now-a-days, this process has become very popular worldwide. People are doing research on image steganography and inventing new even stronger algorithms for image steganography. Hiding data in cover image by modifying bits of that is now optimized by so many new algorithms. Enthusiastic people are increasing demand of researching on image steganography and developing PC software and mobile application using different developing tools, programming languages and their own invention, algorithms etc. Steganography is the process of hiding a secret message within a larger one, in such a way that someone cannot know the presence or contents of the hidden message. Although related, steganography is not to be confused with Encryption, which is the process of making a message unintelligible. Whereas, steganography attempts to hide the existence of communication. The main advantage of steganography algorithm is because of its simple security mechanism. Because the steganographic message is integrated invisibly and covered inside other harmless sources, it is very difficult to detect the message without knowing the existence and the appropriate encoding scheme.
