Biometric matching technology
First Claim
1. A system comprising:
- a database storage;
at least one processor; and
at least one memory coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising;
managing, in the database storage and for each of a plurality of reference images, a) data for persons on a watch list using similarity scores for the respective reference image that represent, for each of the persons on the watch list, a similarity between the respective reference image and an image of the person and b) associations to biometric data for the persons on the watch list;
accessing an image of a potential suspect;
determining at least one criterion relevant to the image of the potential suspect based on at least one of sensor or camera data;
selecting, as a reference image, a single reference image from among the plurality of reference images based on the at least one criterion;
computing a similarity score that represents a similarity between the image of the potential suspect and the selected reference image based on selecting the single reference image;
searching the watch list using the computed similarity score and the selected reference image;
identifying, using a result of the search of the watch list using the computed similarity score, a subset of persons on the watch list each having a similarity score within a threshold of the computed similarity score for the selected reference image;
determining whether the potential suspect matches a person in the subset of the persons on the watch list; and
outputting a result based on determining whether the potential suspect matches a person in the subset of the persons on the watch list.

Abstract
Biometric matching technology, in which a watch list is managed, multiple images of a potential suspect are accessed, and parallel pre-processing of the multiple images is controlled. Based on the pre-processing, an image of the potential suspect to use in matching against the watch list is determined and the determined image is used to search sorted biometric data included in the watch list. A subset of persons from the watch list is identified based on the search and parallel analysis of the determined image of the potential suspect against detailed biometric data associated with the subset of persons in the watch list is controlled. Based on the parallel analysis, it is determined whether the potential suspect matches a person in the watch list and a result is outputted based on the determination.
