摘要
A biometric identification or authentication images an ear of the user. A source of near-infrared structured light illuminates the ear with at least one structured pattern and an image acquisition device captures a near-infrared image of an ear illuminated with a structured pattern of near-infrared light. An analysis area of the near-infrared image is processed to extract identifying features and it is determined if the identifying features correspond to an authorized user. The analysis area of the near-infrared image is processed to determine a reflectivity of the ear and it is determined if the reflectivity corresponds to an ear of a living person. The user is authenticated if the classified identifying features correspond to an authorized user and the reflectivity corresponds to an ear of a living person.
