     EXAMPLE EMBODIMENT 
     Hereinafter, a monitoring system, a monitoring center device, a mounting device, a monitoring method, a processing method, and a program according to one embodiment of the present invention will be described with reference to drawings. 
       FIG. 1  is a schematic diagram of a monitoring system according to the embodiment. 
     In a monitoring system  100  as shown in  FIG. 1 , a mounting device  1  mounted on a vehicle  10  and a monitoring center device  2  are connected via a communication network. The mounting device  1  may communicate and connect with the monitoring center device  2  using, for example, public wireless communication, and may communicate and connect with the monitoring center device  2  via a relay device by performing short-range wireless communication with the relay device wired-connected with the monitoring center device  2  installed at a roadside machine or a position close to a traveling road. 
       FIG. 2  is a hardware configuration diagram of the mounting device. As shown in  FIG. 2 , the mounting device  1  includes, for example, respective hardware constituents such as a central processing unit (CPU)  101 , a read only memory (ROM)  102 , a random access memory (RAM)  103 , a hard disk drive (HDD)  104 , a user interface  105 , a communication module  106 , a camera  107 , a Global Positioning System (GPS) receiver  108 , and the like. The user interface  105  is, for example, a liquid crystal touch panel or a button. The mounting device  1  may be configured to further include other hardware. 
       FIG. 3  is a functional block diagram of the mounting device and the monitoring center device. 
     The mounting device executes a program stored in the ROM  102  or the like of the mounting device, thereby including each function of a photographing unit  11 , a feature transmission unit  12 , a position information acquisition unit  13 , a monitoring unit  14 , a movement detection unit  15 , a start control unit  16 , an image transmission unit  17 , and a communication unit  18  therein.  
     The photographing unit  11  included in the mounting device  1  performs photographing by controlling the camera  107 , and generates an image by this photographing. The photographing unit  11  is installed in a vehicle to photograph a face of a driver of the vehicle and the inside of the vehicle and can photograph moving images and still images. 
     The feature transmission unit  12  recognizes the face of the driver on the basis of the image photographed by the camera  107  and obtained by the photographing unit  11  and extracts feature data of a person. The feature data in the present embodiment is data including at least feature information on the face of the driver. The feature transmission unit  12  may extract feature data of the faces of passengers boarding the vehicle in addition to the driver. The feature transmission unit  12  transmits monitoring data including the feature data, position information of the vehicle  10  acquired by the position information acquisition unit  13 , time measured by a timer in the mounting device  1  to the monitoring center device  2 . When the feature data cannot be generated from an image, the feature transmission unit  12  may request the image transmission unit  17  to transmit the image, perform processing to alert the driver, or notify the monitoring unit  14  that the feature data cannot be generated. 
     The position information acquisition unit  13  calculates a current position of the vehicle  10  on the basis of information included in a signal from a satellite obtained from the GPS receiver  108 . 
     The monitoring unit  14  transmits the feature data to a predetermined service device such as the monitoring center device  2 . A service device in the present embodiment is the monitoring center device  2 . 
     The movement detection unit  15  detects that the vehicle  10  has moved on the basis of acceleration and position information. The movement detection unit  15  may detect states of a vehicle such as a stopping state, a stopped state, and a traveling state. The movement detection unit  15  can transmit movement states (stopping, stopped, and traveling) of the vehicle  10 . 
     The start control unit  16  acquires a determination result from the monitoring center device  2  according to the transmission of the feature data to the monitoring center device  2 , and controls starting of a vehicle on which the mounting device  1  is mounted on the basis of the determination result. The start control unit  16 , as an example, may perform control to start a vehicle when two conditions such as performance of a starting operation of a vehicle using an ignition switch or a key, and acquisition of starting permission by the monitoring unit  14  are satisfied. 
     The image transmission unit  17  performs processing of transmitting images acquired from the camera  107  by the photographing unit  11 . The communication unit  18  communicates and connects with the monitoring center device  2 . 
     The monitoring center device  2 , like the mounting device  1 , is a computer including hardware such as a CPU, a ROM, a RAM, an HDD, a user interface, and a communication module. The CPU of the monitoring center device  2  executes a program, and thereby the monitoring center device  2  includes each function of a monitoring processing unit  21 , a recording unit  22 , a communication unit  25 , and a notification unit  26 . In addition, the monitoring center device  2  includes a qualified person database  23  and a wanted person database  24 . 
     The monitoring processing unit  21  in the monitoring center device  2  searches for the qualified person database  23  storing information on a driver&#39;s license possessed by a police institution or the like and the wanted person database  24  in which feature data of a wanted person such as a wanted criminal is recorded. The monitoring processing unit  21  collates feature data stored in these databases with feature data obtained from the mounting device  1  and determines whether they match each other. The monitoring processing unit  21  transmits a determination result of the collation to the mounting device  1 . 
     The recording unit  22  stores monitoring data including feature data and the like of a person transmitted from the feature transmission unit  12  of the vehicle  10 . 
     The qualified person database  23  holds data of a driver&#39;s license, data of a face photograph of a person on the driver&#39;s license, and personal feature data of the person. 
     The wanted person database  24  holds data of a face photograph of a wanted person such as a wanted criminal and other personal feature data. 
     The communication unit  25  is a processing unit which communicates and connects with the mounting device  1 . 
     The notification unit  26  performs processing of notifying a predetermined transmission destination of an abnormality when it is determined that there is an abnormality on the basis of the feature data. The notification unit  26  may transfer the abnormality notification to the predetermined transmission destination on the basis of an abnormality notification signal from the mounting device  1 . 
     The mounting device  1  and the monitoring center device  2  include such respective functions, and thereby it is possible to reliably monitor a driver of a vehicle and to accumulate monitoring information. Accordingly, this can help with investigations and search and rescue operations of police, firefighting, and the like when there are incidents, accidents, and disasters. 
       FIG. 4  is a first diagram which shows a processing flow of the mounting device. 
     Next, processing of the embodiment of the present invention will be described in order. 
     First, a driver performs a staring operation of a vehicle using an ignition switch or a key in a cockpit to start the vehicle  10 . The camera  107  is installed to photograph the face of the driver. The starting operation starts the mounting device  1 . The photographing unit  11  controls a photographing operation of the camera  107  (step S 101 ). Then, the camera  107  starts photographing and outputs photographed data to the photographing unit  11 . This photographed data includes data of the face of the driver. The photographing unit  11  generates an image on the basis of the photographed data and output the image to the feature transmission unit  12 . 
     The feature transmission unit  12  acquires images (step S 102 ). The feature transmission unit  12  determines whether feature data of the face of the driver has been extracted from the image (step S 103 ). The feature transmission unit  12  determines whether the number of times it is determined that the feature data of the face of the driver cannot be extracted reaches a predetermined number (step S 104 ). The feature transmission unit  12  outputs alert information when No is determined in step S 104  (step S 105 ). A case of outputting alert information is a case in which feature data cannot be extracted when the driver&#39;s posture is bad or when the driver wears a mask or sunglasses. In addition, the alert information is information prompting the driver to enable personal feature data to be extracted, and is output by screen display, voice, and the like. If Yes is determined in step S 104 , the feature transmission unit  12  cannot recognize a face image or cannot extract the feature data. For this reason, the feature transmission unit  12  transmits the inability to extract the feature data to the monitoring center device  2 . 
     If the feature data has been extracted, the feature transmission unit  12  instructs the monitoring unit  14  to transmit the feature data. The monitoring unit  14  acquires information on a current position of the vehicle  10  from the position information acquisition unit  13 . The monitoring unit  14  acquires a current time. The monitoring unit  14  transmits monitoring data including at least the feature data, position information, and the current time to the monitoring center device  2  via the communication unit  18  (step S 106 ). The monitoring unit  14  determines whether monitoring data has been transmitted. The monitoring unit  14  outputs a signal indicating that monitoring data cannot be transmitted to the start control unit  16  when monitoring data cannot be transmitted. 
     The monitoring unit  14  determines whether a determination result based on transmission of monitoring data is received from the monitoring center device  2  (step S 107 ). The determination result includes various information such as a qualified person flag, a wanted person flag, a still image transmission flag, and a moving image transmission flag. The qualified person flag is a flag indicating whether a person corresponding to the feature data has a qualification. The wanted person flag is a flag indicating whether a person corresponding to the feature data is a wanted person. The still image transmission flag is a flag indicating whether it is necessary to transmit a still image. The moving image transmission flag is a flag indicating whether it is necessary to transmit a moving image. When Yes is determined in step S 107 , the monitoring unit  14  analyzes the determination result (step S 108 ). 
     The monitoring unit  14  analyzes the qualified person flag in analysis processing. In addition, the monitoring unit  14  analyzes the wanted person flag in the analysis processing. In addition, the monitoring unit  14  analyzes the still image transmission flag in the analysis processing. In addition, the monitoring unit  14  analyzes the moving image transmission flag in the analysis processing. The monitoring unit  14  performs processing based on a result of the analysis (step S 109 ). 
     Specifically, the monitoring unit  14  output starting permission to the start control unit  16  when it is determined that the qualified person flag indicates that a person has the qualification. The monitoring unit  14  may not output starting permission to the start control unit  16  when it is determined that a qualified person flag indicates that the person does not have the qualification. 
     When the still image flag is a value indicating that it is necessary to transmit the still image, the monitoring unit  14  instructs the image transmission unit  17  to transmit the still image. When the moving image transmission flag is a value indicating that it is necessary to transmit the moving image, the monitoring unit  14  instructs the image transmission unit  17  to transmit the moving image. The image transmission unit  17  sequentially inputs images from the photographing unit  11 . The photographing unit  11  generates the moving image on the basis of a plurality of images acquired from the camera  107  and transmits the moving image to the image transmission unit  17 . The image transmission unit  17  transmits the moving image to the monitoring center device  2  via the communication unit  18  when a transmission instruction of the moving image is acquired. The image transmission unit  17  transmits one still image in images constituting the moving image to the monitoring center device  2  via the communication unit  18  when a transmission instruction of the still image is acquired. 
     After the moving image or the still image is transmitted in accordance with a determination result from the monitoring center device  2 , the mounting device  1  receives a monitoring completion signal from the monitoring center device  2 . The monitoring completion signal is acquired by the monitoring unit  14 . If the monitoring unit  14  acquires the monitoring completion signal, the monitoring unit  14  outputs starting permission to the start control unit  16 . The start control unit  16  outputs a signal for starting a vehicle to an engine control device when two conditions such as performance of a starting operation of a vehicle using an ignition switch or a key and acquisition of starting permission by the monitoring unit  14  are satisfied (step S 110 ). This starts an engine of the vehicle  10 . 
     As described above, the vehicle  10  can be started when a starting operation of a vehicle using an ignition switch and a key and monitoring are performed. Accordingly, it is possible to reliably monitor the driver when the vehicle  10  starts. 
     When communication between the mounting device  1  and the monitoring center device  2  cannot be performed for any reason, the monitoring unit  14  may temporarily store the still image and the moving image without transmitting them to the monitoring center device  2  on the basis of a determination result obtained from the monitoring processing unit  21 . In this case, the monitoring unit  14  may output starting permission of the vehicle  10  to the start control unit  16  without acquiring a monitoring completion signal from the monitoring center device  2 . The monitoring unit  14  can send the still image and the moving image temporarily stored after the communication between the monitoring center device  2  and the mounting device  1  is restored. 
     While the vehicle  10  moves, the monitoring unit  14  performs monitoring processing again if the operation of the vehicle  10  continues for a certain period of time. A monitoring processing procedure is the same as the processing shown in  FIG. 4 . The monitoring unit  14  may not perform monitoring processing when it is determined that the vehicle  10  is started but not moving. Accordingly, it is possible to reliably monitor the driver even when the vehicle  10  is in operation. 
       FIG. 5  is a diagram which shows a processing flow of the monitoring center device. 
     The monitoring processing unit  21  of the monitoring center device  2  performs person authentication using monitoring data transmitted by the mounting device  1  (step S 501 ). The monitoring processing unit  21  collates feature data extracted from the monitoring data with feature data recorded in the qualified person database  23  (step S 502 ). When matching feature data is detected in the collation processing of step S 502 , the monitoring processing unit  21  stores the feature data and sets the qualified person flag to a value indicating that a person has a qualification. 
     In addition, the monitoring processing unit  21  collates the feature data extracted from the monitoring data with feature data recorded in the wanted person database  24  (step S 503 ). When matching feature data is detected in the collation processing of step S 503 , the monitoring processing unit  21  stores the feature data and sets the wanted person flag to a value indicating that a person is the wanted person. 
     If the wanted person flag is set to the value indicating that the person is the wanted person, the monitoring processing unit  21  sets the still image flag to a value indicating that it is necessary to transmit the still image or sets the moving image flag to a value indicating that it is necessary to transmit the moving image. The monitoring processing unit  21  transmits a determination result holding various types of flags to the mounting device  1  (step S 504 ). 
     When the qualified person flag included in the determination result is a value indicating that the person is not the qualified person, and the wanted person flag included in the determination result is a value indicating that the person is not the wanted person, this indicates that no feature data is recorded in both the qualified person database  23  and the wanted person database  24 . In this case, the feature data providing this determination result is feature data not held in the monitoring center device  2 , and the monitoring unit  14  of the mounting device  1  transmits the still image to the monitoring center device  2 . The monitoring processing unit  21  of the monitoring center device  2  determines whether a still image is received (step S 505 ). When the still image is received, the monitoring processing unit  21  outputs a face image and the feature data corresponding to the face image to the recording unit  22 . The recording unit  22  records the face image and the feature data corresponding to the face image in a database (step S 506 ). As a result, monitoring data is stored. As described above, the monitoring unit  14  is requested to add the feature data to be monitored and the face image. The monitoring center device  2  can reliably monitor a driver and further store the monitoring data.  
     The monitoring processing unit  21  of the monitoring center device  2  determines that it is an emergency when the inability to extract feature data is acquired by the mounting device  1  or when feature data included in monitoring data is stored in the wanted person database  24 . When the feature data cannot be extracted, there is a possibility that a driver maliciously refuses monitoring and authentication, and the monitoring processing unit  21  can transmit an instruction to strengthen monitoring to the mounting device  1 . The monitoring unit  14  of the mounting device  1  may instruct the image transmission unit  17  to deliver a moving image when information to strengthen monitoring is received. Accordingly, the monitoring center device  2  can perform real-time monitoring. In addition, when the inability to extract the feature data is received by the monitoring processing unit  21 , the notification unit  26  of the monitoring center device  2  may transmit notification information including the face image and the feature data to a device at a predetermined report destination. 
     By performing such monitoring of a driver, it is possible to expect a crime suppression effect such as hesitation of a crime by a person who drives. When it can be confirmed by notification information that a person is a wanted person, it is possible to contribute to the arrests of wanted persons by notifying an investigation institution and strengthening monitoring on the vehicle  10  as described above. 
     In addition, when feature data is recorded in the qualified person database  23  by collation processing, the monitoring processing unit  21  may record information such as suspension of a driver&#39;s license, license invalidation, and an unauthorized vehicle in correlation with the qualified person information of the qualified person database  23 . With this processing, it is possible to detect an obvious driving violation. In this manner, this processing can be used in catching a violation. 
     The monitoring center device  2  can ascertain a situation in which a driver is a learner on a temporary license, a foreigner who drives a rental car, or the like when feature information is not recorded in any database according to a result of performing collation processing using two databases of the qualified person database  23  and the wanted person database  24 . In this case, the monitoring center device  2  can request not only the feature data of a driver but also the face image of the driver to the mounting device  1 , and store and monitor monitoring data including the face image. 
     By constructing a monitoring system with the mounting device  1  and the monitoring center device  2 , it is possible to expect an effect of crime prevention. In addition, monitoring data such as face images and stored feature data can be searched by a person and person feature information, and this can help with tracking, investigating, and searching for and rescuing persons of interest. Therefore, it is possible to detect and prevent various types of crimes in addition to theft in a moving body such as various vehicles. 
     The monitoring unit  14  of the mounting device  1  may permit starting of the vehicle  10  even in a situation in which communication with the monitoring center device  2  is not possible. In addition, the monitoring unit  14  may request the feature transmission unit  12  to transmit personal feature data when the vehicle  10  continuously runs for a certain distance or more on the basis of state information of the vehicle  10 . Moreover, when notification that the feature transmission unit  12  cannot extract personal feature data is continuous, it is possible to determine that it is an emergency, and it is possible to notify the monitoring center device  2  that it is an emergency. 
     When feature data of a driver is recorded in the wanted person database  24 , the notification unit  26  can notify a predetermined device to that effect as an emergency. In addition, the monitoring processing unit  21  can instruct monitoring strengthening such as continuous photographing and transmission of moving images and transmission of still images to the mounting device  1 . For example, when feature data of a driver is recorded in the qualified person database  23  and the feature data of the driver is recorded in the qualified person database  23  in accordance with information on license suspension, the monitoring processing unit  21  can notify a device possessed by a predetermined institution to that effect via the notification unit  26 . 
     In addition, the monitoring processing unit  21  can instruct the monitoring unit  14  to strengthen monitoring such as transmission of still images. For example, when the monitoring processing unit  21  is notified that it is an emergency by the mounting device  1 , the monitoring processing unit  21  can notify a predetermined device to that effect via the notification unit  26 . Moreover, the monitoring processing unit  21  can instruct the monitoring unit  14  to strengthen monitoring such as transmission of still images. 
       FIG. 6  is a diagram which shows a minimum configuration of the mounting device. 
     The mounting device  1  as shown in  FIG. 6  may be a device including at least a photographing unit  11 , a feature transmission unit  12 , and a start control unit  16 . 
       FIG. 7  is a diagram which shows a minimum configuration of the monitoring center device. 
     The monitoring center device  2  as shown in  FIG. 7  at least includes a monitoring processing unit  21  which determines whether feature data received from the mounting device  1  is recorded in a database, and performs monitoring processing on the basis of a result of the determination.
