Information hiding is an art which has been used since long back for covert communication. Steganography is the art of hiding secret message within a larger image or a secret image in another cover image, such that the hidden message or an image is undetectable. Chaotic systems are known for its randomness, it can be made utilized in achieving the encryption. In this paper chaos-based encryption algorithm for images is used. This algorithm is based on pixel scrambling where in the randomness of the chaos is made utilized to scramble the position of the pixels. Random pixel insertion method is used for hiding the secrete image in cover image. This Application is developed using the Java programming language in Android Software Development Kit. This application created for the Android operating system can be used in smart mobile phones for sending any image in a secrete manner by hiding it in another larger image.
