Description

The aim of this work is to develop an application which can be used for privacy and security purposes over an open environment like internet. The application also provides multilayer security in the form of steganography, which is used to hide the data into the image and secondly, cryptography in order to encrypt the image with a key. Application developed is based on Image Steganography by converting the data into streams of bits and then hiding the data inside an image. Digital images are considered better because of their high usage not only in the daily life activities but also on internet. The objective of this application is to provide a safe and secret communication to business and security sectors for transmitting their secret data on internet without getting attention of intruders. This method is considered better than encryption because the data is invisible to others which prevents from wrong attention and make communication secure.
