ABSTRACT

The significance of digital information security has been heightened due to advances in internet communication. The security of server-client communication over the internet is a critical issue due to digital eavesdroppers. Generally, username and password authentication is required for establishing a connection between server and client environment. The client username and password are verified by the server ends to establish a valid connection. Successful username and password verification initiates the client and server to perform further secure request and response mechanisms. This paper proposed a secure username and password transmission over the internet for authentication of server-client environment using encryption and image steganography. Client username and password are first encrypted and embedded in an image using steganographic algorithm at client side and transmitted over unsecured network to the web server. On the other side, the server extracts the username and password from image steganography decoding algorithm, decrypt and verified it?s with SQL database server. In case if the intruder steals the image over network he/she will be unable to decode the password from the image.
