Title: Innovations by Lawrence R Thebaud
Introduction
Lawrence R Thebaud is an accomplished inventor based in Agoura Hills, CA. He holds a total of 3 patents that showcase his expertise in identity verification technologies. His work focuses on systems and methods that enhance security through advanced fingerprint analysis.
Latest Patents
One of his notable patents is titled "Systems and methods with identity verification by comparison & interpretation of skin patterns such as fingerprints." This invention involves a sensor that receives a print image from an authorized person to create a template, while also capturing test data from a candidate. The technology estimates noise variance from the test data based on position in the image, which is crucial for accurate comparison with the template. The process includes storing a ridge spacing and direction map of the template as vector wavenumber fields, which refine the comparison. The resulting test statistic helps determine whether the test image was formed by an authorized user, thereby controlling access to various systems.
Another significant patent is "Systems and methods with identity verification by streamlined comparison and interpretation of fingerprints and the like." This invention also utilizes a sensor to capture print images and involves comparing power spectral density (PSD) data for both the template and candidate. The technology adjusts for rotation and dilation, allowing for a more accurate correlation. The normalized spatial correlation values (NSCVs) serve as a quality measure for the match, leading to early rejection or acceptance decisions based on thresholding.
