Abstract
Systems, devices and methods for use in biometric identification are disclosed for use resolution of ambiguity as to what identity is being asserted and/or which reference identities are to be used to build a gallery for identification. In implementations, are described to resolve ambiguity and in particular situations in which a unique authoritative identifier is unavailable for use in locating relevant references to serve as the basis for biometric matching and identification.
Claims29
A system comprising a computer comprising:
- a processing system having a hardware processor configured to perform a predefined set of basic operations by loading corresponding ones of a predefined native instruction set of codes, the predefined native instruction set of codes constituting a set of instructions selectable for execution by the hardware processor;
- a memory accessible to the processing system;
- a user interface controller under control of the processing system;
- user interface logic, stored in the memory, comprising a sequence of instructions selected from the predefined native instruction set of codes of the hardware processor, adapted to operate with the processing system and the user interface controller to implement a user interface adapted to obtain, from a person, proffered biographic information as an asserted identity of the person;
- a biometric capture system, including a sensor configured to obtain current biometric information of the person, under control of the processing system;
- a communication system, under control of the processing system, adapted to transmit a query, based on the proffered biographic information, and to receive corresponding identity records of individuals;
- biographic information comparator logic, stored in the memory, comprising a respective sequence of instructions selected from the predefined native instruction set of codes of the hardware processor, adapted to calculate a respective measure of biographic similarity between the proffered biographic information and saved biographic information received in one of the corresponding identity records;
- biometric information comparator logic, stored in the memory, comprising a respective sequence of instructions selected from the predefined native instruction set of codes of the hardware processor, adapted to compute a respective measure of biometric similarity for only ones of the corresponding identity records where the respective measure of biographic similarity exceeds a predetermined biographic similarity threshold;
- the processing system being further configured to output an access control signal when the respective measure of biometric similarity exceeds a predetermined biometric similarity threshold;
- and
- access control circuitry, responsive to the access control signal and configured to control a state of an access control device.
