The present disclosure describes systems and methods for iris liveness determination. A sensor can acquire a first image of an iris with pupillary constriction, and a second image of the iris without the pupillary constriction. A processor can extract an iris portion of the first image into a first iris image, and an iris portion of the second image into a second iris image. The processor can normalize the first iris image and the second iris image. The normalized first iris image can have same dimensions as that of the normalized second iris image, in pixels. The processor can compute a minimum average difference between values of specific pixels of the normalized first iris image and values of corresponding pixels of the normalized second iris image. The specific pixels can correspond to an innermost annular portion of the iris.

The present disclosure describes systems and methods for acquiring a biometric image. A biometric camera system can position a lens of a biometric camera between a pixel array of the biometric camera and an iris. The pixel array can acquire an image of the iris using light reflected from the iris and transmitted through the lens of the biometric camera. The lens can increase a pixels per iris (PPi) value of the image of the iris acquired by the pixel array, by applying optical positive distortion to the light reflected from the iris when the light is optically directed through the lens. A processor can provide a biometric image for biometric matching, by image-processing the acquired image of the iris having the increased PPi value, with an inverse function of the optical positive distortion.

The present disclosure is directed towards a compact, mobile apparatus for iris image acquisition, adapted to address effects of ocular dominance in the subject and to guide positioning of the subject's iris for the image acquisition. The apparatus may include a sensor for acquiring an iris image from a subject. A compact mirror may be oriented relative to a dominant eye of the subject, and sized to present an image of a single iris to the subject when the apparatus is positioned at a suitable distance for image acquisition. The mirror may assist the subject in positioning the iris for iris image acquisition. The mirror may be positioned between the sensor and the iris during iris image acquisition, and transmit a portion of light reflected off the iris to the sensor.

METHODS AND APPARATUS FOR POWER-EFFICIENT IRIS RECOGNITION
Disclosed herein are systems and methods wherein the iris biometric of an individual person is acquired using a mobile or static device. This acquisition may involve the use of active illumination and repeated use of the camera and processor, as examples. These modules consume considerable power however, and this can significantly reduce battery life. There is a need therefore for a power-efficient iris recognition system.

Method for confirming the identity of an individual while shielding that individual's personal data
A method for confirming the identity of an individual while shielding that individual's personal data. At least one biometric such as the image of the iris of an individual is captured and stored in a database. A unique identification code is assigned to the biometric without reference to the first individual's personal information. A subsequent biometric data collect is compared with the contents of the database. If a match between the subsequent biometric is found with the original biometric, the system transmits the identification code corresponding to the matched biometric. In a second aspect of the invention, in order to protect the privacy of individuals, the unique identification code is encrypted such that only the individual to whom the biometric belongs holds the de-encryption key. In a third aspect of the invention also intended to protect the privacy of individuals, a non-unique group identification code is assigned to the biometric. Preferably, in the case where the biometric used is the iris, the system replaces enrollment and live iris images with iris templates and bases comparisons on these templates, rather than storing/comparing actual images. The system is adapted to assist in locating missing persons and in verifying transactions. If an individual is missing and a live iris template is matched to that person's stored template, the system automatically contacts another individual.

Method of reducing visibility of pulsed illumination while acquiring high quality imagery
A method of providing active illumination during biometry that utilizes pulsed lighting synchronized to frame acquisition. Two distinct illumination modalities are provided: the first maximizes the quality of images captured by the imaging system, and the second minimizes the overall illumination perceived by the user in combination with the first. The two modalities are provided substantially simultaneously. The first modality always includes a set of pulses synchronized with frame acquisition. The second modality may be either a second set of pulses not synchronized with frame acquisition or constant background illumination. The two modalities may be generated by two separate sources of illumination or by the same single illumination source. Adding the second modality to the first reduces user discomfort and the chances of an epileptic response as compared to using the first modality alone. The two modalities may have different wavelengths, pulse durations, or intensities.

Operator interface for face and iris recognition devices
A primarily hand-held or adjustable-mount iris recognition device wherein feedback to the operator is provided by visible illumination or imagery projected onto the face of the subject, as well as an audio signal, while infra-red illumination is projected onto the face of the subject as an illumination source for an iris recognition process. When the device is pointed in the direction of the subject, the infra-red illumination is directed to illuminate primarily the eye region whereas the visible illumination is directed to illuminate primarily other regions including the cheeks. The visible illumination is configured such that the position of the visible illumination on the face indicates to the operator whether the iris recognition device is pointed in the correct direction and at the correct distance for optimal iris recognition. The brightness of the visible illumination is modified in response to the result of an eye detection process performed on the iris recognition device, and the brightness, color and other attributes of the visible illumination or the audio signal are modified in response to the result of eye-finding or other process, including the results of an iris recognition process.

The provenance of passengers intending to depart on a vehicle from a transportation facility, is ensured by providing biometric reading devices at both a check-in station and a departure area station of the facility. The name and/or other information concerning a passenger arriving at the facility is also entered for assessment into a background check system. A biometric template of the passenger is acquired by the reading device at the check-in station and forwarded to the departure area station. When the passenger appears at the latter station, a second biometric template is acquired by the reading device there. The second template is compared with each of a number of templates that were forwarded from the check-in station. If no match exists, or if the background check system returns an unsatisfactory assessment, the passenger is refused boarding onto the vehicle.
