Abstract: A biometric access control system for controlling access to an environment based on an authorization status of a living subject is disclosed. In one example, a data source generates image data of a tissue region of the subject. A liveness measurement unit processes the image data to detect changes over at least one of time or spatial volume in one or more structural features of the tissue region and generates, based on the detected changes, a spoofing attack detection status indicating that the image data is from living biological tissue or that a spoofing attack is detected. A biometric identification unit processes at least a portion of the same image data generated by the data source to generate biometric information indicative of an identity of the subject. Responsive to the spoofing attack detection status and the biometric information, an authorization unit outputs an authorization status for the subject.

Abstract: A method and apparatus for biometric iris matching comprising pre-processing an input image capturing one or more eyes to produce one or more rectified iris images, coding the one or more rectified iris images into one or more multiresolution iris codes and matching the one or more multiresolution iris code with a set of stored multiresolution iris codes to determine whether a match exists.

Abstract: Techniques for verifying identity of a human subject to an identification document are described. In some examples, a computing device may be connected to least two cameras oriented such that a first field of view is a substantially opposite direction from a second field of view. The device may receive images from the first camera that include a human subject. Second images from the second camera may include images of an ID document with a photograph of the human subject. The device may process the first images along with the respective, corresponding second images to determine respective 3D locations for at least one of cameras at the respective times the images were captured. Based on the sequence of 3D locations, along with the first images and the second images, the device may determine whether the human subject is a valid human subject.

Abstract: An iris biometric recognition module includes technology for capturing images of an iris of an eye of a person, whether the person is moving or stationary, and whether the person is located near the iris image capture device or at a distance from the iris image capture device. The iris biometric recognition technology can perform an iris matching procedure for, e.g., authentication or identity verification purposes. The iris biometric recognition module can be incorporated into, for example, a door lock assembly and other access controlled devices, mechanisms, and systems.
