Vehicle monitoring apparatus, fraud detection server, and control methods

1. A vehicle monitoring apparatus which assists in detecting that a target vehicle is a fraudulent vehicle, the vehicle monitoring apparatus comprising:

a first communicator that receives specifying information for specifying the target vehicle from a server;

a processor; and

a memory storing at least one set of instructions that, when executed by the processor causes the processor to perform operations including:

acquiring driving information from the target vehicle, the driving information being information regarding driving of the target vehicle specified by the specifying information received by the first communicator,

wherein the driving information of the target vehicle includes speed information that indicates a speed of the target vehicle,

wherein the first communicator transmits the driving information acquired to the server,

wherein, in the acquiring, the driving information obtained from the target vehicle through communication is obtained,

wherein, in the acquiring, the driving information obtained by sensing the target vehicle is obtained,

wherein the operations further include: determining whether or not first driving information that is the driving information obtained through the communication and second driving information that is the driving information obtained by the sensing match, and

wherein the first communicator transmits the first driving information and the second driving information to the server only when it is determined in the determining that the first driving information and the second driving information do not match.

2. The vehicle monitoring apparatus according to claim 1 ,

wherein the vehicle monitoring apparatus is provided in a vehicle, and

in the acquiring, it is presented, to a driver of the vehicle, question information for asking a driving state of the target vehicle, and the driving information based on answer information to the question information acquired from the driver by sensing is acquired.

3. A fraud detection server which assists in detecting that a target vehicle is a fraudulent vehicle, the fraud detection server comprising:

a first communicator that receives first driving information that is information regarding driving of the target vehicle;

a second communicator that receives second driving information from the vehicle monitoring apparatus of one or more vehicles other than the target vehicle;

wherein the first driving information and the second driving information includes speed information that indicates vehicle speed,

a memory that stores position information that indicates current positions of the one or more vehicles other than the target vehicle;

a processor; and

the memory storing at least one set of instructions that, when executed by the processor causes the processor to perform operations including:

when an anomaly is detected in the first driving information received from the target vehicle, specifying the one or more vehicles other than the target vehicle that are present within a predetermined distance from the target vehicle from among the one or more vehicles other than the target vehicle by referencing the position information, and transmitting a notification requesting for second driving information regarding driving of the target vehicle to a vehicle monitoring apparatus of each of the one or more vehicles specified, an anomaly being a condition in which a frame received by a vehicle-mounted network of the target vehicle is fraudulent; and

determining priority based on the first driving information and the second driving information, the priority indicating a degree of precedence in which the anomaly needs to be preferentially analyzed, and more preferentially transmitting a notification of the anomaly as the anomaly has higher priority,

wherein, when it is determined that the first driving information and the second driving information do not match, higher priority is given in the notification to the anomaly detected in the first driving information.

4. A control method for controlling a vehicle monitoring apparatus which assists in detecting that a target vehicle is a fraudulent vehicle, the control method comprising:

receiving specifying information for specifying the target vehicle from a server;

acquiring driving information from the target vehicle, the driving information being information regarding driving of the target vehicle specified by the specifying information received,

wherein the driving information of the target vehicle includes speed information that indicates a speed of the target vehicle; and

transmitting the driving information acquired to the server,

wherein, in the acquiring, the driving information obtained from the target vehicle through communication is obtained,

wherein, in the acquiring, the driving information obtained by sensing the target vehicle is obtained,

wherein the control method further includes: determining whether or not first driving information that is the driving information obtained through the communication and second driving information that is the driving information obtained by the sensing match, and

wherein the first driving information and the second driving information are transmitted to the server only when it is determined in the determining that the first driving information and the second driving information do not match.

5. A control method for controlling a fraud detection server which assists in detecting that a target vehicle is a fraudulent vehicle, the control method comprising:

receiving first driving information that is information regarding driving of the target vehicle;

storing position information that indicates current positions of a plurality of vehicles other than the target vehicle;

when an anomaly is detected in the first driving information received from the target vehicle, specifying one or more vehicles other than the target vehicle that are present within a predetermined distance from the target vehicle from among the plurality of vehicles other than the target vehicle by referencing the position information, and transmitting a notification requesting for second driving information regarding driving of the target vehicle to a vehicle monitoring apparatus of each of the one or more vehicles specified, an anomaly being a condition in which a frame received by a vehicle-mounted network of the target vehicle is fraudulent;

receiving the second driving information from the vehicle monitoring apparatus of the one or more vehicles other than the target vehicle; and

determining priority based on the first driving information and the second driving information, the priority indicating a degree of precedence in which the anomaly needs to be preferentially analyzed, and more preferentially transmitting a notification of the anomaly as the anomaly has higher priority,

wherein the first driving information and the second driving information includes speed information that indicates vehicle speed,

wherein, when it is determined that the first driving information and the second driving information do not match, higher priority is given in the notification to the anomaly detected in the first driving information.
