Abstract
Methods and systems for biometric identification. Identification accuracy confidence is improved in one-to-many biometric matching by determining the mobile devices present in the area of the subject-to-be-identified, and determining the set of people associated with the mobile devices. Biometric profiles may be filtered using the set of people determined to be in the location of the subject-to-be-identified based on mobile device presence. The resulting subset provides higher confidence identification if a match is found with a profile belonging to a member of the subset.
Claims22
A method of identifying a person located in a defined geographic area using an electronic device, the electronic device including at least one memory unit that includes stored biometric data for a set of people, the method comprising:
- obtaining biometric information from the person in the defined geographic area and information related to one or more devices located within the defined geographic area;
- obtaining, from a stored set of associations between people and devices, one or more identified people based on the information related to one or more devices located within the defined geographic area;
- reducing the set of people to a subset of people based on the one or more identified people;
- detecting a sufficient match between the biometric information and the stored biometric data associated with an individual from the subset of people;
- and
- outputting a signal identifying said individual as the person.
A system for identifying a person located in a defined geographic area, the system comprising:
- at least one memory unit that includes stored biometric data for a set of people;
- and
- an electronic system having
- at least one biometric input device to obtain biometric information from the person in the defined geographic area,
- a communications unit to obtain information related to one or more devices located within the defined geographic area and to obtain, from a stored set of associations between people and devices, one or more identified people based on the information related to one or more devices located within the defined geographic area, and
- a processor to reduce the set of people to a subset of people based on the one or more identified people, detect a sufficient match between the biometric information and the stored biometric data associated with an individual from the subset of people, and cause output of a signal identifying said individual as the person.
