Claim One:
1. A method of detecting a living human eye comprising the steps of: presenting a first image on a display, wherein the display is oriented to face a user; positioning at least one camera proximate the display, wherein the at least one camera is oriented to face the user so that light emitted by the display as the first image is reflected by the user and captured by the at least one camera; obtaining a second image through the at least one camera; and using a computing device to perform: determining whether at least a portion of the second image includes a representation of the first image on the display reflected by a curved surface consistent with a human eye, wherein the step of positioning the at least one camera proximate the display comprises positioning the at least one camera 75 to 500 mm from the user and wherein the step of determining whether the at least the portion of the second image includes the representation of the first image on the display reflected by the curved surface consistent with a human eye comprises determining whether the representation of the first image is 12.5 to 166.7 times smaller than that of a reflection off a flat surface.
