US Patent 9942761 User access verification

Embodiments are directed to a method of providing access verification for a system that includes activating a security control device, which is in communications with a host device. The method also includes having the security control device receiving a verification signal coming from outside the system while being locally-based, and comparing the verification signal to a table of stored criteria values. The device then chooses a response based on that comparison and sends an access determination signal based on the response.
