Abstract
An access control system is described along with a method for operating the system. In one example, a system and method are disclosed that provide a hands-free solution thereby enabling a user to walk through a door or portal with no stop in motion and limited to no interaction or user effort. Security of the system is still maintained even though user interactions are significantly decreased.
Claims20
A physical access control system, comprising:
- a biometric sensor mounted in proximity to a physical access control point;
- and
- a reader comprising:
- an antenna that enables the reader to wirelessly communicate with one or more access control credentials;
- a processor coupled to the antenna;
- and
- memory coupled to the processor that stores instructions thereon that are executable by the processor, the instructions comprising:
- instructions that determine an estimated spatial relationship between an access control credential within read range of the antenna and the reader;
- instructions that use the estimated spatial relationship to reduce a number of biometric templates that are analyzed by the processor in connection with determining whether or not a carrier of the access control credential is allowed to gain entry through the physical access control point, wherein the number of biometric templates are reduced from N templates to at least N-1 templates;
- and
- instructions that perform a comparison of biometric information obtained via a biometric sensor with one or more biometric templates in the reduced number of biometric templates.

A method of maintaining security of a door and permitting an automated actuation of the door with a reader, the method comprising:
- determining an estimated spatial relationship between an access control credential and the reader;
- based on the estimated spatial relationship and an access control identifier (ID) communicated to the reader by the access control credential, selecting one or more templates from a database that contains a plurality of templates, wherein a number of templates in the selected one or more templates is less than the plurality of templates;
- obtaining biometric information for a user that is approaching the reader;
- comparing the obtained biometric information with only templates belonging to the selected one or more templates;
- based on the comparison, determining that the biometric information satisfies a template belonging to the selected one or more templates;
- and
- in response to determining that the biometric information satisfies the template, allowing the reader to automatically actuate the door or a component of the door.
