Abstract: Systems and methods of biometric identification of a subject have steps of providing a light source and an imager, positioning a subject hand palm facing the light source and imager, illuminating the palm with the light source, capturing an image of the palm, and determining characteristics of capillary beds in the image. The present invention may include the step of identifying the subject based on the characteristics of the capillary beds. The step of determining characteristics of capillary beds in the image may include determining locations of the capillary beds. The present invention may include the step of processing the image to filter image features of the palm other than the capillary beds. Processing the image to filter image features of the palm other than the capillary beds may include removing surface ridge pattern features and spatially filtering to remove detail with a frequency of less than a selected threshold.
Abstract: Methods, systems, and programming for user identification and authentication are presented. In one example, an apparatus for user authentication is disclosed. The apparatus comprises: a surface on which an object is placed; a light source configured for providing light illuminating a first portion of the surface; a brightness measuring unit configured for measuring brightness distribution in a second portion of the surface, wherein the brightness distribution is caused by the object that spreads the light from the first portion to the second portion; and a determiner configured for determining whether the object is an organic body part based on the brightness distribution.
