Portable authentication device and method using iris patterns

摘要

A compact, handheld imaging apparatus which can be used to capture high-quality iris images for identification of a person. The handheld iris imager is non-invasive and non-contacting and comprises a camera, a cold mirror, a lens, and an illuminator. The imager has sensors and indicators which assist a user in aligning and focusing the device. The imager also automatically captures the image when proper positioning is achieved. A template of the image is then transmitted to a receiver in a vehicle or other asset and compared to a database of previously stored templates of images to identify the person. The imager is part of a security module to protect access to an asset such as a vehicle or residence. The vehicle or residence cannot be unlocked and used unless a user has been identified and authorized by the imager and a controller system.
