Image Steganography Using Cryptography Techniques



Abstract

In this traditional world the issues of providing the higher security to the information have been emerging a lot of various (miscellaneous) activities that has lead the corporate world to many serious problems. In this corporate world the main security must be provided to the private information from being manipulated during the transmission or the communication rather than the hardware parts. These emerging miscellaneous activities may cause a lot of damage to the data which may lead to the loss of the corporate companies. In order to provide security for the data in this project I am using a new concept called the STEGNOGRAPHY that is derived from a Greek word which actually means hidden data transmission. This is achieved by hiding one type of file format into the other type of file format. As I am developing this project as a web application, the source will be in the JAVA language. The implementation of this project at the end have met all the basic and main aims of the security and is proven to be suited perfectly for the issues concerning to the information security. As the project has been successfully implemented, I gained a complete and good knowledge on this subject.

Synopsis

My project provides a high level security to the data that is being transmitted from place to the other place. In my project I have used a new method called “Stegnography”. In the method of cryptography the security is provided by just encrypting the data using any encryption algorithms. Where as in the case of Stegnography besides encryption the data is also hidden ...
