Patent ID: 8224034

Claim:
A building entrance biometrics system commonly utilized by predetermined persons, for authenticating a person to access the building entrance through a comparison between biologic information gotten from the person and registered reference biologic information of the person comprising: a biologic information sensor, which is provided in the building entrance biometrics system, arranged to sense the biologic information of the person to be authenticated; an administrator, which is provided in the building entrance biometrics system, arranged to administrate registration of the reference biologic information of the person sensed by the sensor in the building entrance biometrics system, the registered reference biologic information being used in comparison with the biologic information sensed by the biologic information sensor upon authenticating the person to access the building entrance; a transmitter, which is provided in the building entrance biometrics system, arranged to transmit the registered reference biologic information obtained from the biologic information sensor in the building entrance biometrics system, to a portable device which is configured to operate independently and separately outside the building entrance biometrics system and which is carried by the person to have the portable device store the registered reference biologic information separately from the building entrance biometrics system, whereby the registered reference biologic information comes to belong to the person under his/her private control within the portable device, a controller arranged to delete the registered reference biologic information to be used in coming authentication from the building entrance biometrics system after the transmission of the registered reference biologic information to the portable device, whereby the registered reference biologic information to be used in coming authentication is isolated from the biometrics system, wherein the portable device is a mobile-phone.
