Abstract:
1. A method A method to authenticate a user at an automated teller machine (ATM), the method comprising: receiving by a processor of the ATM communicatively coupled to a memory, numeric data identifying the user but unexclusive thereto; comparing by at least one of: the processor of the ATM and a processor of a remote server communicatively coupled to the ATM, the received numeric data with stored numeric data in a database associated with the remote server; narrowing by the at least one of: the processor of the ATM and the processor of the remote server, a search space within the database associated with the remote server based on the comparison of the received numeric data into a first search space, the first search space comprising a plurality of users identified by the numeric data received from the user, and the plurality of users including the user providing the numeric data; receiving by the processor of the ATM, biometric identification data of the user from at least one of: a fingerprint scanner, an iris scanner and a camera communicatively coupled to the processor of the ATM following the narrowing of the search space into the first search space; extracting by the processor of the ATM, a partial biometric identifier of the user from the received biometric identification data in a first operation; comparing by the at least one of: the processor of the ATM and the remote server, the extracted partial biometric identifier of the user with stored biometric identification data in the database associated with the remote server in the first operation; narrowing by the at least one of: the processor of the ATM and the processor of the remote server, the first search space into a second search space based on the comparison of the extracted partial biometric identifier of the user in the first operation; extracting by the processor of the ATM, a second biometric identifier of the user from the received biometric identification data in at least one second operation temporally succeeding the first operation, the extracted second biometric identifier being a more unique identifier of the user than the extracted partial biometric identifier thereof; comparing by the at least one of: the processor of the ATM and the remote server, the extracted second biometric identifier of the user with the stored biometric identification data in the database associated with the remote server in the at least one second operation; narrowing by the at least one of: the processor of the ATM and the processor of the remote server, the second search space into a third search space based on the comparison of the extracted second biometric identifier of the user in the at least one second operation; and providing by the processor of the ATM, the user access to financial account information unique thereto only when the third search space solely includes the user providing the biometric identification data and the numeric data.
