Graphics Based Authentication for Secured Database Using Edge-LSB Technology

At present, there many security mechanism available for the data security purpose. One of them is most commonly used characters, numbers, special symbols etc and password for the authentication purpose. If the password is difficult to guess then it is also difficult to remember. To overcome this method new strategy is developed as picture as password which is also referred to as graphical authentication. This security aspect can be conquered with the help of the security aspects like cryptography, steganography and Edge-LSB Technology. Currently, the security paradigm is moving from one layer security to two layer security paradigm. Where first layer is cryptography and second layer is steganography, which hides the data. So, we provide the new technique to hide the data in the images with help of Edge LSB algorithm. Edge-LSB hides the data in the edge pixel of the image which prevents hacking of the data.
