US 7,277,891 B2 · Systems and methods for recognition of individuals using multiple biometric searches

Abstract

The invention provides a computer-implemented method for determining whether a database contains any images that substantially match at least one image provided of an individual. A probe data set is received, the comprising first and second biometric templates associated with the individual, the first biometric template associated with a different type of biometric than the second type of biometric template. A database of biometric templates is searched using the first biometric template to retrieve a first results set. A first predetermined portion of the first results set is selected. The first predetermined portion of the first results set is searched using the second biometric template to retrieve a second results set. A second predetermined portion of the second results set is selected. The second predetermined portion of the second results is provided for comparison with the image provided of the individual.

Dependent claims

A computerized system for determining whether a database contains an image substantially matching that of a given probe candidate, the system comprising:

an input device constructed and arranged to receive first and second biometric search templates associated with the probe candidate, the first biometric search template associated with a first type of biometric identifier and the second biometric search template associated with a second type of biometric identifier;
a first database comprising a plurality of searchable biometric templates, the plurality of searchable biometric templates comprising a plurality of templates of the first type of biometric and a plurality of templates of the second type of biometric;
a first biometric search engine operably coupled to the input device and to the first database, the first biometric search engine adapted to search the first database of searchable biometric templates for a match to the first biometric template and return a first set of results;
a second biometric search engine operably coupled to the input device and to the first database, the second biometric search engine adapted to search the first database of searchable biometric templates for a match to the second biometric template and return a second set of results;
a processor in operable communication with the input device and the first and second biometric search engines, the processor programmed to compare the first and second sets of results to the first and second biometric templates to determine whether any result in the first set of results or the second set of results is a substantial match to either the first or second biometric search templates associated with the probe candidate;
wherein the first set of results includes at least one new template that is used as a new probe to direct the search of the second biometric search engine.

A computer-implemented method for determining whether a database contains any images that substantially match an image associated with an individual, comprising:

(a) receiving an initial probe data set, the initial probe data set comprising a biometric template associated with the individual;
(b) searching a database of biometric templates using the initial probe data set to retrieve a results set, the results set comprising biometric templates that satisfy a predetermined first criteria;
(c) selecting a first portion of the results set to be a refined probe data set;
(d) searching the database of biometric templates using the refined probe data set to return a results set, the results set comprising biometric templates that satisfy the predetermined first criteria;
(e) repeating (c) and (d) until a stop condition is reached;
and
(f) returning the last results set retrieved before the stop condition is reached as a final results set.
