System and method for authenticating an end user

摘要

A method for authenticating an end user. The method begins by generating a login field in response to receiving an authentication request from an end user. The login field comprises a login node matrix comprising a first set of transparent and opaque nodes in addition to at least one login offset. Next the method determines an authenticity status of the end user by comparing data received from the end user with said first set of transparent nodes. The data received being sent in response to sending the login field to the end user. The end user generated the data by overlaying a transparent credit card on top of the login field and aligning the login offset with a card offset and then selecting at least one node which is not opaque. Finally, the method sends the determined authenticity status to the end user via an output device.
