Hiding file on Android mobile and sending APK file through whats app using steganography and compression techniques

By using different ways users can send and receive information on android mobiles. Security is major issue while sharing these file on android platforms. Steganography also have some limitations in embedding capacity of data. By using appropriate compression algorithm we can reduce the size of data. Also WhatsApp doesn't allow user to share apk file. In this paper we have developed an android app by means of which we can hide data behind image and we can share apk file through WhatsApp. This app is developed by using steganography and LZMA compression technique. Advantage of this app is it provides the double security by using steganography and compression.
