Abstract
A system and method are diminish the use of an automated program in a networked environment. A server can provide access to a service. In addition, a software module provides a client computer with a visual test upon a request transmitted through a network by the client computer for the service. The visual test requires the client computer to perform a predetermined action on a shaped object displayed on a video display in order to gain access to the service. A validation software module receives a request from the software module for the shaped object to be displayed on the video display. Further, the validation software module randomly selects a shaped object to be transmitted to the software module. The validation software module provides the software module with the shaped object. An access software module receives an access instruction from the validation software module if the client computer passes the visual test. The client computer can access the service if the client computer passes the visual test.
