Abstract
An authenticity accuracy, corresponding to a personal identification number, is determined. A device presents a correct image (or group of images) and an incorrect image (or group of images). Selections from a user are received until a sufficient number of correct images are selected to satisfy the authenticity accuracy. For example, a counter may be incremented when the correct image is selected, and the user may be considered to be authenticated if the counter reaches a sufficient level.
