1. A machine-implemented method for authenticating a user session, comprising the steps of: displaying a selected digital image on a display screen; receiving a user drawing template executed by a user over said selected digital image; associating a user drawing template member with a user position template; and determining if the user drawing template member and the digital image match in part and if a user position selection corresponds to said user position template for authenticating access to the user session when the user position selection substantially duplicates said user position template.
