Resumen
The invention relates to a person recognition method and device incorporating the anatomic location of the retina as a biometric constant, corresponding to the physiological location of the projection of the visual axis. More specifically, the invention relates to a person recognition method and a corresponding device incorporating the anatomic location of the retina as an exclusive discriminant biometric constant for each individual, corresponding to the physiological location of the visual axis, taking account of the physiological fixation disparity. The invention combines five elements, namely: an optical input system for examining the fundus of the eye, for example by means of retinal scanning or through the sclera; a system providing an expanded view of the retina, for example formed by converging lenses, diverging lenses and/or prisms or mirrors; a system for identifying and marking the anatomic point corresponding to the physiological point of the projection of the visual axis, such as a laser; a system of filters having different transmittance and optical density values; and a system for capturing and processing digital images, such as an optical digital camera. In addition, the invention can take the form of a portable, auto-focusing device with automatic control.
