Steganography Encryption Standard For Android Application

Abstract:-

Steganography is an art of hiding information. The difference between steganography and cryptography is that the goal of cryptography is to hide the content of message, whereas the goal of steganography is to conceal the very fact that the message exists. in younger days of steganography, lossless images were actively used as cover images. Algorithms were based on embedding the secret bits into least significant bits (LSB) of pixels with minor alternations. This approach was heavily criticized by Westfeld and Pfitzmann. In modern era, when vast majority of images are encoded in JPEG format, usage of lossless images is at least questionable. So, in order to avoid suspicion, one has to use JPEG files. Image steganography allows two individuals to communicate privately. We have develop an android application using this technique to securely send secret image and text message by hiding them in image without worrying about man-in-the-middle attack by protecting image with password. This provide security from attacker. We use LSB algorithm that is efficient algorithm in. Image of JPEG,BMP and PNG type can be used in our application as cover image and as an input secret image. This application didn’t change the type of original image after hiding secret information in it.
