Latest Patents

Daugman's latest patents include the "Fast focus assessment system and method for imaging" and the "Biometric personal identification system based on iris analysis." The first patent describes an imaging apparatus designed to capture high-quality iris images for identification purposes. This system includes a camera, cold mirror, lens, illuminator, and a focus assessment processor. The device assists users in aligning and focusing for optimal image capture, automatically taking the image once proper positioning is achieved. The focus assessment processor evaluates the image quality and controls indicators to ensure accurate alignment.

The second patent outlines a system for rapid and automatic identification of individuals using their iris as an optical fingerprint. This system boasts high reliability and confidence levels. It employs image analysis algorithms to locate the iris in live video images and encodes its unique texture into a compact signature known as an "iris code." The extraction process utilizes a set of quadrature bandpass filters, and the resulting iris codes can be compared using the Exclusive-OR logical operation. This method allows for effective pattern recognition and establishes a confidence level for identification decisions.
