The method of file security through Cryptography and Steganography

Abstract

Today technology changes so fast and our lives are totally dependent on computer and networks. There is a huge number of files on the network for communication over the network. These files are stored on server and this introduces security threats also. Many Organizations such as Banking, University
and Medical store their sensitive data for day-to-day operation of their organization. So the security is the most important factor for handling such interactive transactions. File security is the one type of mechanism that is used to secure and authenticate the file.
