This article proposed a graphical password authentication which uses chunks of images to overcome the loopholes present in the traditional authentication methods. The graphical password contains a selection of chunks of images which creates password for authenticating cloud users for accessing cloud services. The article includes the details of chunks of images authentication, algorithm and implementation of chunk of images.
