This is closest to the traditional username, password system.

Here, besides having your username and password on the first screen, you will have to select an additional picture from the list on the PDSS™ screen once your username and password is verified. The additional level of security imposed is easy to use, easy to remember and prevents many of the issues posed by phising, keylogging, auto fill etc and may provide the benefit of having an universal username/password across all your accounts by offering an additional shell on the PDSS™ screen. This picture can be changed, as many times as an user wants as it is convenient to use and easy to remember.

The system will lock oneself out after a set number of failed attempts.

Also the choice keeps changing its sequence among the choices displayed.
