Abstract: A looking away determination device includes: a looking away determination unit that determines that a driver is in a looking away state when a proportion of an image in which a face having a degree of certainty equal to or greater than a threshold value is shown with respect to a plurality of images obtained by imaging the driver, the degree of certainty serving as an index of face likeness; and an updating unit that updates the threshold value based on a degree of certainty of a face shown in an image obtained by imaging the driver.

Abstract: Sensing information indicating a state of a moving body is acquired. A plurality of captured images that capture a driver driving the moving body are acquired. From the plurality of captured images, captured images captured in a state of the moving body traveling forward based on the sensing information. A reference line of sight direction in a case of the driver facing forward is detected based on a statistical value of a line of sight direction of the driver indicated by each of the identified captured images.

Abstract: A person specifying device includes an authentication unit configured to acquire a captured image capturing a person boarding a moving vehicle, to perform a matching determination as to whether or not the person reflected in the captured image matches a pre-registered person, and to generate person-specifying information representing the person determined via the matching determination; and an authentication-interval-updating unit configured to update a time interval for performing the matching determination to be shorter when failing to achieve a success frequency of authentication above a desired value via the matching determination.

Abstract: Face image acquiring means acquires a face image of an authentication target person from a captured image of an imaging device. Authentication means verifies the acquired face image of the authentication target person with the registered image, and performs authentication with respect to the authentication target person. When the authentication succeeds, calculation means verifies the face image of the authentication target person with a face image obtained when the authentication target person has succeeded in the authentication in the past, and calculates a score. Determination means determines whether to prompt the authentication target person to update the registered image based on the calculated score. Notification means transmits a notification prompting the authentication target person to update the registered image.

Abstract: An authentication apparatus includes biometric information acquiring part which acquires first biometric information of user, certification information adding part, authentication part, and biometric information database which includes second biometric information of user stored in advance. The certification information adding part receives first biometric information from biometric information acquiring part, generates certification information concerning communication rule, notifies authentication part of certification information in advance, and transmits authentication information including certification information and first biometric information configured according to the communication rule shown by certification information to authentication part. The authentication part receives authentication information, verifies legitimacy of certification information in authentication information received using certification information notified in advance, and performs authentication of user using first biometric information in authentication information according to the communication rule shown by certification information with reference to second biometric information in a case where certification information is determined to be legitimate.

Abstract: A driving-state monitoring system includes a driving-state monitoring device and a driving-state sensing device. The driving-state sensing device captures an image of a driver of a vehicle to thereby generate driving-state data. The driving-state monitoring device acquires the driving-state data and the captured image of a driver of a vehicle from the driving-state sensing device. An authentication process is made to determine whether or not a driver matches a pre-registered driver based on the information of a driver included in the captured image, thus determining the identification information of the driver successfully authenticated. The driving-state data is recorded on a database in association with the identification information of the driver. Accordingly, it is possible for the driving-state monitoring device to monitor a plurality of vehicles using a plurality of driving-state sensing devices, thus precisely managing a plurality of vehicles in terms of their driving states.

Abstract: A camera is installed in a vehicle in which a plurality of seat rows are arranged, and captures an image of an inside of the vehicle. A face detection unit detects a face region of a passenger from the image captured by the camera. A seating row specification unit specifies a seat row in which the passenger with the face region being detected is seated. A seating position specification unit specifies a seat position of the passenger in the vehicle, based on a range of a seat position in the image and the seat row being specified, the range of the seat position being prepared for each seat row.
