  • Publication number: 20220368520
    Abstract: According to an embodiment, an access control device includes a first communication interface, a second communication interface and a processor. The processor acquires, from the key device, an identifier functioning as the key identification information and a biometrics authentication result; transmits a confirmation request signal to the confirmation device, when the key identification information of the key device agrees with key identification information of a valid key and when the biometrics authentication result is an authentication failure; and permits access to the security device, upon receiving a confirmation response signal indicative of the access permission from the confirmation device in response to the confirmation request signal.

  • Publication number: 20220108558
    Abstract: According to an embodiment, a biometric authentication device includes a biometric authentication sensor, a housing, a battery, and a power supply circuit. The biometric authentication sensor is configured to be brought into contact with any finger of fingers and acquire biometric authentication information from the finger. The housing disposes the biometric authentication sensor so as to be exposed to a part of an outer surface and can be held by the fingers. The battery is provided in the housing. The power supply circuit is configured to start supply of power from the battery by the biometric authentication sensor being pressed down in a state where the finger is in contact with the biometric authentication sensor.

  • Patent number: 10250567
    Abstract: A wireless communication circuit includes a receiver to receive at least one of a beacon frame and a probe response frame from a first wireless communication apparatus belonging to a first communication group, at least one of the beacon frame and the probe response frame including first security information indicating a first encryption method. The circuit includes a transmitter to transmit an association request frame to the first wireless communication apparatus, the association request frame including second security information indicating a second encryption method which is supported by the wireless communication circuit, after a determination that the second encryption method overlaps with the first encryption method. The transmitter declines to associate with the first wireless communication apparatus if the first encryption method fails to overlap with the second encryption method. The transmitter transmits a data frame including a frame body after a reception of an association response frame.
