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: determining one or more devices that are located within the defined geographic area; obtaining biometric information from the person in the defined geographic area and information related to the 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, the subset being an intersection between the set of people and the one or more identified people; determining whether a sufficient match is found between the biometric information and the stored biometric data associated with an individual from the subset of people, wherein a sufficient match is obtained with a threshold adjusted for achieving a desired degree of confidence; and in response to determining that a sufficient match is found within the subset of people, outputting a signal identifying said individual as the person, wherein the signal further includes a confidence level in the identification, the signal indicating a first confidence level; and in response to determining that no sufficient match is found within the subset of people, determining whether a sufficient match is found between the biometric information and the stored biometric data associated with an individual from the set of people but not from the subset of people; and in response to determining that a sufficient match is found within the set of people but not from the subset of people, outputting a second confidence level that is lower than the first confidence level, and granting reduced-access to the person in response to a request for access based on the second confidence indication and/or requesting second factor authentication from said individual. determining one or more devices that are located within the defined geographic area; obtaining biometric information from the person in the defined geographic area and information related to the 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, the subset being an intersection between the set of people and the one or more identified people; determining whether a sufficient match is found between the biometric information and the stored biometric data associated with an individual from the subset of people, wherein a sufficient match is obtained with a threshold adjusted for achieving a desired degree of confidence; and in response to determining that a sufficient match is found within the subset of people, outputting a signal identifying said individual as the person, wherein the signal further includes a confidence level in the identification, the signal indicating a first confidence level; and in response to determining that no sufficient match is found within the subset of people, determining whether a sufficient match is found between the biometric information and the stored biometric data associated with an individual from the set of people but not from the subset of people; and in response to determining that a sufficient match is found within the set of people but not from the subset of people, outputting a second confidence level that is lower than the first confidence level, and granting reduced-access to the person in response to a request for access based on the second confidence indication and/or requesting second factor authentication from said individual.
