Graphic Password Authentication

Our project is about designing an authentication system where we will use images as passwords. First, we need to ask the user to register his email and then we will the user to give 4 images on his own which will be the default image password sequentially. Then the system will provide another 12 images by default. We will ask the user to use his password in 4 layers. In the first layer, the first image of his password sequence will be mixed stored in an address along with another 3 images that were by defaultly provided by the system. The same will also happen in the other 3 layers. The 16 images will be depicted as numbers from 0-9 and some special symbols that won't be shown to the user. With every log-in trial the main 4 images that were provided by the user will be shuffled within the layer but the other 12 images that are by default, will swap with each other and also from one layer to another layer also. To avoid shoulder surfing system need to have a mouse handling and keyboard handling system.
