Description

The present invention relates to a security device, a vehicle equipped with the security device, and an authentication method, and is particularly suitable for use in a security device and an authentication method for preventing unauthorized use of the vehicle on the go.

Conventionally, a password-based security device has been widely used as a security device that permits access to an information processing system and execution of processing on the condition that the validity of the target is confirmed. In addition, biometric authentication technology using biometric information such as iris, facial features, fingerprints, and veins is often used.

Recently, biometric authentication technology has begun to be introduced in the automobile industry as well. For example, by identifying an individual by biometric authentication, it is expected that not only will it be possible to provide a driving environment and information tailored to the individual, but it will also be used for opening and closing door locks and controlling engine on / off. In particular, in the case of a car, there are relatively many cases where it is stolen on the go, so how to realize security on the go becomes a problem.

The color component data of the clothes of a person who can access the information processing system is registered in the storage means in advance, and when the dates are the same, the color components of the clothes of the user who is the subject included in the photographed image. And, a security device is also known in which it is determined whether or not the user is a legitimate licensee by comparing with the information of the storage means, and the use of a person other than the licensee is restricted (for example). See Patent Document 1).

JP-A-11-96477

However, with security devices that use biometric authentication technology, unauthorized access by impersonating the person is endless. In addition, as in the technique described in Patent Document 1, authentication using the color component of clothes prevents fraud such as another person wearing the same clothes as the person or clothes having the same color component and impersonating the person. I can't. Therefore, further strengthening of security is desired.

The present invention has been made to solve such a problem, and an object of the present invention is to enable more effective deterrence of unauthorized use of a vehicle on the go.

In order to solve the above-mentioned problems, in the present invention, the occupant information storage unit stores in advance the occupant information including the number of occupants riding in the vehicle and the characteristics of at least one of the occupants on the day of boarding. When the occupant's boarding on the vehicle is detected, the number of occupants and the characteristic items are collated with the occupant information stored in the occupant information storage unit, and the number of occupants and the characteristics of the occupant's boarding day are collated. If at least one of the items does not match, the authentication is not permitted.

According to the present invention configured as described above, authentication is performed using two pieces of information: the number of occupants riding in the vehicle and the characteristics of at least one of the occupants on the day of boarding. The number of occupants and the characteristics of the occupants on the day of boarding are information that can fluctuate depending on the time when the vehicle goes out, and since two types of information are used, this information is used by a third party who intends to use the vehicle illegally. It becomes difficult to match with. Thereby, according to the present invention, it is possible to effectively prevent the unauthorized use of the vehicle on the go.

(First Embodiment)
Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a functional configuration example of a security device in a vehicle according to the first embodiment. As shown in FIG. 1, the security device 101 according to the first embodiment is mounted on a vehicle, and its functional configuration includes an operation reception unit 11, an occupant information registration unit 12, an occupant information storage unit 13, and a passenger. It is configured to include a detection unit 14, an occupant detection unit 15, a collation unit 16, another authentication execution unit 17, and a fraud prevention control unit 18.

Each of the above functional blocks 11 to 18 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, each of the above functional blocks 11 to 18 is actually configured to include a CPU, RAM, ROM, etc. of a computer mounted on a vehicle, and is a recording medium such as RAM, ROM, hard disk, or semiconductor memory. It is realized by operating the program stored in. The occupant information storage unit 13 is configured to include a non-volatile recording medium.

It is assumed that the security device 101 of the present embodiment is always in operation by using the battery even when the accessory switch of the vehicle is set to off. When the accessory switch of the vehicle is off, the security device 101 is inactive, and when the vehicle control device (not shown) that controls various vehicles detects the release of the vehicle door lock, security is provided. The device 101 may be turned on to start up.

The operation reception unit 11 receives an operation on the security device 101 by the user. For example, the operation reception unit 11 receives a user operation on a touch panel or the like. The touch panel used here does not have to be provided exclusively for the security device 101, and may be generally provided by the in-vehicle device.

In this embodiment, in particular, an operation for inputting occupant information, which will be described later, is accepted by a legitimate occupant who gets on the vehicle. A legitimate occupant in a vehicle is, for example, the owner of the vehicle and its affiliates (family, friends, acquaintances, etc.). If the vehicle is a rental car or a shared car, the renter of the vehicle and its affiliates are legitimate occupants.

The occupant information registration unit 12 stores the occupant information input through the operation reception unit 11 in the occupant information storage unit 13 in response to the operation by the occupant received by the operation reception unit 11, thereby storing the occupant information in the security device. Register with 101. The occupant information stored in the occupant information storage unit 13 is information including the number of occupants riding in the vehicle and the characteristics of at least one of the occupants on the day of boarding.

At least one of the occupants is that occupant if there is only one occupant, and at least one of them if there are multiple occupants. Hereinafter, this at least one occupant is referred to as a "specific occupant". For example, it is possible to set a driver who always exists regardless of whether there is one or more occupants as a specific occupant, and to use at least the characteristics of the driver on the day of boarding as occupant information.

The characteristics of the occupant on the day of boarding are not the characteristics of the occupant who do not change every day (for example, the physical characteristics of the occupant), but the characteristics that can change from day to day. One example is the clothing of the occupants. In addition, the clothes are not limited to those worn by the occupants, and may be worn by the occupants such as earrings or carried by the occupants such as bags. However, it is preferable to use the clothes that the specific occupant (driver) always has as a characteristic item on the day of boarding. In the following, it will be described that the clothes of the occupants are used as a characteristic item on the day of boarding.

When clothing is used as a feature of the day of boarding, for example, the occupant information registration unit 12 stores the color information of the clothing input by the occupant through the operation reception unit 11 in the occupant information storage unit 13. When the clothes of the occupant include a plurality of colors, the occupant information storage unit 13 stores the plurality of color information. Here, the input of the color information performed through the operation reception unit 11 can be, for example, an operation of selecting a color palette close to the color of the clothes from the color palette displayed on the touch panel. In this case, the color palette is such that a plurality of typical colors are displayed in a palette format, and any color can be selected by a user operation.

Alternatively, the clothes of the specific occupant may be photographed by using the camera function possessed by the mobile terminal such as a smartphone owned by the occupant, and the photographed image may be input to the security device 101 through the user operation on the touch panel. In this case, the mobile terminal and the security device 101 are connected by a wired cable such as USB (Universal Serial Bus) or a wireless communication means such as Bluetooth (registered trademark).

When the photographed image is input and the color information of the clothes is stored in the occupant information storage unit 13, the occupant information registration unit 12 recognizes the input photographed image of the specific occupant as an image, extracts the clothing area, and within the clothing area. Color information is generated by analyzing the color components of the image contained in. In this case, the analyzed color component (for example, when the color component is represented by 256 gradations, the value of 0 to 255 for each of red, blue, and green) may be used as the color information, and the analyzed color component may be used as the color. The color information may be replaced with the closest color in the palette. Whether the former or the latter color information is used depends on the design of how much the security strength is enhanced.

The occupant information registration unit 12 registers the occupant information as described above in the occupant information storage unit 13, for example, before the start of use of the vehicle. Before the start of use of the vehicle means before the start of driving. That is, when the occupant gets into the vehicle, the occupant operates the touch panel to input the occupant information before starting the operation, and the occupant information registration unit 12 stores the input occupant information in the occupant information storage unit 13. Remember. It should be noted that the registration of occupant information is not necessarily required to be performed before starting the operation. At the very least, it should be done before the occupant gets off the vehicle.

The boarding detection unit 14 detects the boarding of the occupant on the vehicle. The detection method is arbitrary, and a known technique can be used. For example, by installing a camera in the vehicle interior and analyzing an image taken by the camera, it is detected that an occupant has entered the vehicle. Alternatively, a weight sensor may be installed in the seat, and the seating of the occupant may be detected by the weight sensor to detect that the occupant has entered the vehicle. Since it is necessary to detect the number of occupants and their clothes in order to perform collation by the collation unit 16 described later, it is preferable to detect the occupants' boarding in the vehicle by analyzing the captured image by the camera.

In principle, it is a legitimate occupant who gets in the vehicle, but there is a possibility that an unauthorized third party will get in the vehicle. In the present specification, both a legitimate occupant and an unauthorized third party are referred to as "occupants".

The occupant information registration unit 12 described above may be used as a trigger for the occupant detection unit 14 to detect the occupant's ride on the vehicle. That is, when the occupant information registration unit 12 detects that the occupant is on the vehicle by the occupant detection unit 14, the occupant information registration unit 12 determines whether or not the occupant information is registered in the occupant information storage unit 13, and is not registered. In this case, it is possible to display the occupant information input screen on the touch panel and store the occupant information input from the screen in the occupant information storage unit 13.

When the occupant detection unit 14 detects the occupant's occupancy, the occupant detection unit 15 detects the number of occupants and the characteristics. That is, the occupant detection unit 15 detects the number of occupants and the characteristics of the occupants by recognizing the captured image input from the camera installed in the vehicle interior. As described above, the characteristic matter of the occupant is the color information of the clothes worn by the occupant.

Here, when any color information in the color palette is used as the color information of the clothes to be stored in the occupant information storage unit 13, the occupant detection unit 15 recognizes the captured image and extracts the clothes area of the occupant. Then, the color component of the image contained in the clothing area is analyzed. Then, the analyzed color component is replaced with the closest color in the color palette, and the color information obtained in this way is detected as a characteristic item of the occupant. On the other hand, when the color component of 256 gradations itself is used as the color information of the clothes stored in the occupant information storage unit 13, the occupant detection unit 15 recognizes the captured image and analyzes the image included in the occupant's clothes area. The color information consisting of the color components of is detected as a characteristic item of the occupant.

The occupant characteristic items detected by the occupant detection unit 15 are not only the characteristic items of the specific occupant but also the characteristic items of all the occupants. That is, when the driver is a specific occupant, the occupant detection unit 15 detects not only the characteristic items of the occupant in the driver's seat but also the characteristic items of the occupant in another seat. This is because there is a possibility that the driver will be replaced when the occupant gets off and gets on again. In addition, when an unauthorized third party gets in the vehicle in an attempt to steal an object in the passenger compartment, he / she does not necessarily get in the driver's seat.

The collation unit 16 collates the information detected by the occupant detection unit 15 (hereinafter referred to as detection information) with the occupant information stored in the occupant information storage unit 13, and determines the number of occupants and the characteristics of the occupant on the day of boarding. If at least one of the items (color information of clothes) does not match, the certification will not be permitted. Here, when there are a plurality of occupants detected by the occupant detection unit 15, the collation unit 16 stores the color information of the clothes detected by the occupant detection unit 15 for each occupant and the occupant information storage unit 13 as occupant information. The stored color information of the clothes is collated individually.

When the detection information for the number of occupants and the occupant information of the occupant information storage unit 13 match, and the detection information and the occupant information of the occupant information storage unit 13 for at least one occupant color information match. Is the authentication permission. On the other hand, when the detection information about the number of occupants and the occupant information of the occupant information storage unit 13 do not match, and / or there is one occupant whose detection information and the occupant information of the occupant information storage unit 13 match with respect to the color information of clothes. If not, authentication is not permitted.

If the verification unit 16 determines that the authentication is not permitted, the occupant at that time is likely to be a fraudulent third party. In this case, the necessary processing is performed to prevent fraudulent acts by the third party. For example, in order to prevent the vehicle itself from being stolen, the accessory power may be locked to prevent it from being turned on, or the engine may be locked to prevent it from starting. Further, the warning information may be transmitted to the mobile terminal of the contact registered in advance in the security device 101.

In the present embodiment, when the verification unit 16 determines that the authentication is not permitted, the above-mentioned processing related to fraud prevention is not immediately executed, but the determination that the authentication is not permitted is executed separately. Notify department 17. The separate authentication execution unit 17 executes another authentication process when the collation unit 16 determines that the authentication is not permitted. For example, the separate authentication execution unit 17 displays a password input screen on the touch panel and causes the occupant to input the password. Then, the entered password is collated with the password registered in advance in the security device 101, and if they match, the authentication is permitted, and if they do not match, the authentication is not permitted.

The security code is registered in the security device 101, for example, when the occupant information registration unit 12 stores the occupant information in the occupant information storage unit 13 through the user operation received by the operation reception unit 11, the security code is also registered. It is possible to do so. That is, the occupant information registration unit 12 stores the password input through the operation reception unit 11 in the occupant information storage unit 13 when a legitimate occupant is on board. In this case, the separate authentication execution unit 17 collates the password entered through the operation reception unit 11 after the verification unit 16 determines that the authentication is not permitted with the password stored in advance in the occupant information storage unit 13. , Judge whether authentication is permitted or not.

Of course, it goes without saying that the personal identification number may be registered in advance by operating the touch panel separately from the registration of the occupant information. The password registered in this case does not have to be a dedicated password for the security device 101. For example, the personal identification number used when activating an in-vehicle device (not shown) such as an audio device or a navigation device may also be used. The personal identification number used to start the in-vehicle device is not changed each time the vehicle is boarded, but is stored in the system memory or the like. In this case, the separate authentication execution unit 17 collates the password entered through the operation reception unit 11 after the verification unit 16 determines that the authentication is not permitted, and collates the password stored in the system memory with the authentication permission or non-permission. Judgment of permission.

The fraud prevention control unit 18 executes the above-mentioned fraud prevention process when it is determined by the separate authentication execution unit 17 that the authentication is not permitted. For example, the fraud prevention control unit 18 is a vehicle control device that controls various types of vehicles by providing instruction information instructing that the accessory power is locked so as not to be turned on or the engine is locked so as not to start. By outputting to (not shown), the vehicle control device is made to execute the above-mentioned locking operation.

Alternatively, the fraud prevention control unit 18 executes a process of transmitting warning information to the mobile terminal of the contact registered in advance in the security device 101. The contact information for transmitting the warning information is registered, for example, when the occupant information registration unit 12 stores the occupant information in the occupant information storage unit 13 through the user operation received by the operation reception unit 11. Is possible. In this case, the separate authentication execution unit 17 reads the contact information stored in the occupant information storage unit 13 and transmits the warning information to the mobile terminal of the contact.

In this way, when the verification unit 16 determines that the authentication is not permitted, the process related to fraud prevention is not immediately executed, but another authentication process is executed by the separate authentication execution unit 17, and the separate authentication execution unit 17 is assigned. The reason why the processing related to fraud prevention is executed when it is determined that the authentication is not permitted is as follows. That is, even if the occupant information registration unit 12 stores the occupant information in the occupant information storage unit 13 to start the operation, the vehicle gets off at a predetermined place (destination, waypoint, etc.), and then a legitimate occupant gets on the vehicle again. This is because the number of occupants or the clothes of the occupants may change.

For example, if the destination or waypoint is the sea or river, there is a possibility that a specific occupant will change clothes after playing. In this case, the collation unit 16 matches the color information of the clothes of each occupant detected by the occupant detection unit 15 with the color information of the clothes of the specific occupant stored as the occupant information in the occupant information storage unit 13. Therefore, it is judged that the authentication is not permitted. At this time, if the processing related to fraud prevention is immediately executed only by the collation by the collation unit 16, the vehicle cannot be used even though the occupant is a legitimate occupant. In order to prevent such a situation, another authentication process by the separate authentication execution unit 17 is executed to provide a way of relief when the clothes are changed.

In addition, if the destination or transit point is a station, etc., one of the crew members may be dropped off and restarted, or a friend who has met may be boarded and restarted, and the number of crew members may change. be. In this case, the collation unit 16 determines that the authentication is not permitted because the number of occupants detected by the occupant detection unit 15 and the number of occupants stored as occupant information in the occupant information storage unit 13 do not match. At this time, if the processing related to fraud prevention is immediately executed only by the collation by the collation unit 16, the vehicle cannot be used even though the occupant is a legitimate occupant. In order to prevent such a situation, another authentication process by the separate authentication execution unit 17 is executed to provide a way of relief when the occupant gets on and off the vehicle.

In addition, when another authentication process is performed by the separate authentication execution unit 17, even if the verification unit 16 determines that the authentication is not permitted because an unauthorized third party has boarded the vehicle, the separate authentication execution unit 17 If the PINs match in another authentication process by, the vehicle can be used illegally. Therefore, in order to prevent such a situation, another authentication is performed only when the verification unit 16 determines that the authentication is not permitted and when either the number of occupants or the clothes of the occupants match. Another authentication process may be performed by the execution unit 17.

For example, if the destination or waypoint is the sea or river, the clothing of a specific occupant may change, but the number of occupants is likely to remain the same. On the other hand, if the destination or waypoint is a station, the number of occupants may change, but the clothes of specific occupants (drivers) are likely to remain the same. In other words, in the case of a legitimate occupant, it is highly likely that either the number of occupants or the clothing of the occupants is the same.

On the other hand, in the case of a fraudulent third party, there is a high possibility that the number of crew members and clothes do not match. Therefore, if the separate authentication execution unit 17 performs another authentication process only when either the number of occupants or the clothes of the occupants match, the separate authentication execution unit can be used for a legitimate occupant. While providing a way to be relieved by another authentication process by 17, it is possible to immediately execute the process related to fraud prevention only by the collation by the collation unit 16 against the fraudulent third party.

FIG. 2 is a flowchart showing an operation example of the security device 101 according to the first embodiment configured as described above. The flowchart shown in FIG. 2 starts when the power of the security device 101 is turned on, for example, triggered by the detection of the release of the door lock of the vehicle.

First, the boarding detection unit 14 analyzes a photographed image input from a camera installed in the vehicle interior to determine whether or not a occupant has boarded the vehicle (step S1). Here, the determination in step S1 is repeated until the occupant's occupancy on the vehicle is detected by the occupancy detection unit 14. Then, when the occupant detection unit 14 detects that the occupant is on the vehicle, the occupant information registration unit 12 determines whether or not the occupant information is already stored in the occupant information storage unit 13 (step S2).

Here, when the occupant information is not stored in the occupant information storage unit 13, the occupant information registration unit 12 displays the occupant information input screen on the touch panel and prompts the occupant to input the occupant information. In response to this, when the occupant operates the touch panel to input the occupant information (the number of occupants and the color information of the clothes of the specific occupant), the occupant information registration unit 12 inputs the occupant information input through the operation reception unit 11. By storing the information in the information storage unit 13, the occupant information is registered in the security device 101 (step S3). After that, the process returns to step S1.

When the registration of the occupant information is completed, the driver starts driving. Then, upon arriving at the destination or waypoint, the occupant disembarks from the vehicle and performs the desired desired action outside the vehicle. Then, the occupant will get on the vehicle again. At this time, the boarding detection unit 14 detects the boarding of the occupant on the vehicle (step S1: Yes). After that, the occupant information registration unit 12 determines that the occupant information is already stored in the occupant information storage unit 13, so the process proceeds to step S4.

In step S4, the occupant detection unit 15 detects the number of occupants on board and the color information of the clothes worn by the occupants by analyzing the captured image input from the camera installed in the vehicle interior (step S4). ). Then, the collation unit 16 collates the detection information output from the occupant detection unit 15 with the occupant information stored in the occupant information storage unit 13 (step S5), and the number of occupants and the color information of the occupant's clothes are collated. It is determined whether or not both of the above match (step S6).

Here, when it is determined that the detection information and the occupant information match with respect to both the number of occupants and the color information of the occupant's clothes, the collation unit 16 grants authentication permission (step S10). In this case, the processing by the fraud prevention control unit 18 is not executed, and the vehicle can be used normally. As a result, the processing of the flowchart shown in FIG. 2 is completed.

On the other hand, if it is determined that at least one of the number of occupants and the color information of the occupant's clothes does not match, the collation unit 16 disallows the authentication and notifies another authentication execution unit 17 to that effect. The separate authentication execution unit 17 confirms the result of the collation by the collation unit 16 and determines whether or not either the number of occupants or the color information of the occupant's clothes match (step S7).

Here, if it is determined by the collation unit 16 that both the number of occupants and the color information of the occupant's clothes do not match, the separate authentication execution unit 17 disallows the authentication (step S11). In this case, the fraud prevention control unit 18 executes the fraud prevention process (step S12). As a result, the processing of the flowchart shown in FIG. 2 is completed.

On the other hand, if it is determined that either the number of occupants or the color information of the occupant's clothes match, the separate authentication execution unit 17 executes another authentication process using the password (step S8). .. Then, it is determined whether or not the personal identification number input from the touch panel and the personal identification number registered in advance in the security device 101 match (step S9).

Here, if the passwords match, the separate authentication execution unit 17 grants authentication permission (step S10). In this case, the processing by the fraud prevention control unit 18 is not executed, and the vehicle can be used normally. On the other hand, if the passwords do not match, the separate authentication execution unit 17 disallows the authentication (step S11). In this case, the fraud prevention control unit 18 executes the fraud prevention process (step S12). As a result, the processing of the flowchart shown in FIG. 2 is completed.

As described in detail above, in the first embodiment, occupant information including the number of occupants riding in the vehicle and the characteristics of at least one of the occupants on the day of boarding is stored in the occupant information storage unit 13 in advance. Keep it. Then, when the occupant detection unit 14 detects that the occupant is on the vehicle, the collation unit 16 notifies the occupant information storage unit 13 with the information detected by the occupant detection unit 15 regarding the number of occupants and the characteristics. If it is determined that both the number of occupants and the characteristics of the occupant on the day of boarding do not match by collating with the stored occupant information, authentication is disapproved. Further, in the first embodiment, when it is determined that only one of the number of occupants or the characteristic items on the day of boarding of the occupants does not match, another authentication execution unit 17 uses another password. Even if the authentication process is executed and it is determined that the passwords do not match, the authentication is not permitted.

According to the first embodiment configured in this way, authentication is performed using two pieces of information: the number of occupants riding in the vehicle and the characteristics of at least one of the occupants on the day of boarding. The number of occupants and the characteristics of the occupants on the day of boarding are information that can fluctuate depending on the time when the vehicle goes out, and since two types of information are used, this information is used by a third party who intends to use the vehicle illegally. It becomes difficult to match with. Even if one of the two types of information happens to match, authentication will not be permitted unless the PIN can also be matched. Thereby, according to the first embodiment, it is possible to effectively prevent the unauthorized use of the vehicle on the go. Further, according to the first embodiment, even if the number of occupants or the clothes of the legitimate occupants changes, the authentication is permitted if the correct PIN is entered, so that the authentication is permitted as usual. You can continue to use the vehicle.

In the first embodiment, the occupant information registration unit 12 has described an example in which the occupant information storage unit 13 stores occupant information through a user operation received by the operation reception unit 11, but the present invention is not limited thereto. .. For example, the occupant information registration unit 12 stores the occupant information (the number of occupants detected from the image captured by the camera and the color information of the occupant's clothes) detected by the occupant detection unit 15 in the occupant information storage unit 13. You may.

Further, in the first embodiment, the occupant information is received through the user operation received by the operation reception unit 11 after the occupant gets on the vehicle, before the occupant starts driving the vehicle, or before the occupant gets off the vehicle. Although the example in which the registration unit 12 stores the occupant information in the occupant information storage unit 13 has been described, the present invention is not limited to this. For example, the occupant information registration unit 12 may store the occupant information in the occupant information storage unit 13 at the timing when it is detected that the occupant is about to get off the vehicle. An example of the functional configuration in this case is shown in FIG.

In addition, in FIG. 3, those having the same reference numerals as those shown in FIG. 1 have the same functions, and therefore, duplicate description will be omitted here. The security device 101'shown in FIG. 3 further includes a disembarkation determination unit 19. Further, the security device 101'shown in FIG. 3 includes an occupant information registration unit 12'and an occupant detection unit 15'in place of the occupant information registration unit 12 and the occupant detection unit 15.

The disembarkation determination unit 19 determines whether or not the occupant is about to disembark from the vehicle. For example, the disembarkation determination unit 19 analyzes an image taken by a camera installed in the vehicle interior to determine whether or not the occupant is performing an operation generally performed when getting out of the vehicle. Determine if the occupant is about to get out of the vehicle. The operation generally performed when the occupant gets out of the vehicle is, for example, the operation of removing the seat belt. Alternatively, it is an action to open the door.

The occupant detection unit 15'detects occupant information regarding the occupant who is about to disembark when the disembarkation determination unit 19 determines that the occupant is about to disembark. That is, the occupant detection unit 15'detects the number of occupants who are about to get off and the color information of their clothes by analyzing the image taken by the camera installed in the vehicle interior. Then, the occupant information registration unit 12'stores the occupant information about the occupant who is about to get off, which is detected by the occupant detection unit 15', in the occupant information storage unit 13.

Further, in the first embodiment, another authentication process using the personal identification number is executed by the separate authentication execution unit 17, and if the personal identification numbers match, the authentication is permitted. On the other hand, if the security code is not input for a certain period of time or more after the security code input screen is displayed on the touch panel, or if the input security code is not valid, the security device 101 is used. A message may be sent to the mobile terminal of the contact registered in advance, and the authentication may be permitted on condition that the consent is input from the mobile terminal.

In this way, even if a legitimate occupant forgets the PIN, the vehicle can be used as usual. On the other hand, if an unauthorized third party fails to authenticate with the PIN code, the message is not sent to the third party's mobile terminal, so authentication permission cannot be obtained. At this time, a message is sent to the mobile terminal of the legitimate occupant registered as the contact information, so that the legitimate occupant notices that the fraud is being committed by a third party and returns to the vehicle as soon as possible to be appropriate. You can take action.

Further, in the first embodiment, an example in which another authentication process using the personal identification number is executed by the separate authentication execution unit 17 has been described, but the other authentication process is not limited to this. For example, it may be an authentication process using biological information such as fingerprints, irises, veins, facial features, and voiceprints.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a block diagram showing a functional configuration example of the security device 102 according to the second embodiment. Note that, in FIG. 4, those having the same reference numerals as those shown in FIG. 1 have the same functions, and therefore, duplicate description will be omitted here.

As shown in FIG. 4, the security device 102 according to the second embodiment further includes a disembarkation detection unit 21 and a disembarkation location detection unit 22 as its functional configuration. Further, the security device 102 according to the second embodiment does not include the separate authentication execution unit 17 shown in FIG. 1, and replaces the collation unit 16 and the fraud prevention control unit 18 with the collation unit 16'and the fraud prevention control unit. It has 18'. Further, the current position detection device 201 and the map data storage unit 202 are connected to the security device 102 according to the second embodiment.

In the first embodiment described above, if the number of normal occupants or clothes changes in the middle, the authentication execution unit 17 is provided in consideration of the fact that the verification by the collation unit 16 disallows the authentication. It was composed. On the other hand, in the second embodiment, even if the number of normal occupants or clothes changes on the way, the verification by the collation unit 16 does not disapprove the authentication.

The disembarkation detection unit 21 detects the disembarkation of an occupant from the vehicle. Unlike the disembarkation determination unit 19 described above, the disembarkation detection unit 21 detects that the occupant has actually disembarked from the vehicle. For example, the disembarkation detection unit 21 analyzes an image taken by a camera installed in the passenger compartment to detect that the passenger has changed from a state in which the passenger is in the passenger compartment to a state in which the passenger is absent. Detects that the vehicle has disembarked.

The disembarkation determination unit 19 may be provided instead of the disembarkation detection unit 21. This is because if the disembarkation determination unit 19 determines that the occupant is about to disembark from the vehicle, it is highly probable that the occupant will actually disembark from the vehicle thereafter.

The disembarkation location detection unit 22 detects the location where the occupant's disembarkation is detected by the disembarkation detection unit 21. That is, the disembarkation location detection unit 22 acquires the current position information from the current position detection device 201 and the map data from the map data storage unit 202, and the occupant is currently disembarking based on the current position information and the map data. Detect the location of. The place where you get off is not the location information such as longitude and latitude, but the terrain such as the sea and rivers, and the facilities such as stations. Here, the current position detection device 201 and the map data storage unit 202 are equivalent to those generally provided in the navigation device, and are provided in the navigation device (not shown) mounted on the vehicle. It is also possible to divert things.

The collation unit 16'performs a collation only for a part of the occupant information stored in the occupant information storage unit 13 according to the disembarkation location detected by the disembarkation location detection unit 22, and performs a matching determination. That is, when the disembarkation location detected by the disembarkation location detection unit 22 is a predetermined location (for example, a station) where the number of occupants may fluctuate, the collation unit 16'matches the number of occupants. Is not implemented. Further, when the disembarkation place detected by the disembarkation place detection unit 22 is a predetermined place (for example, the sea or a river) where the clothes of the occupants may fluctuate, the collation unit 16'is the color of the clothes. Information collation is not carried out.

The fraud prevention control unit 18'executes the fraud prevention processing as described above when the verification unit 16'determines that the authentication is not permitted.

FIG. 5 is a flowchart showing an operation example of the security device 102 according to the second embodiment configured as described above. The flowchart shown in FIG. 5 starts when the power of the security device 102 is turned on, for example, triggered by the detection of the release of the door lock of the vehicle.

First, the boarding detection unit 14 analyzes a photographed image input from a camera installed in the vehicle interior to determine whether or not a occupant has boarded the vehicle (step S21). Here, the determination in step S21 is repeated until the occupant's occupancy on the vehicle is detected by the occupancy detection unit 14. Then, when the occupant detection unit 14 detects that the occupant is on the vehicle, the occupant information registration unit 12 determines whether or not the occupant information is already stored in the occupant information storage unit 13 (step S22).

Here, when the occupant information is not stored in the occupant information storage unit 13, the occupant information registration unit 12 displays the occupant information input screen on the touch panel and prompts the occupant to input the occupant information. In response to this, when the occupant operates the touch panel to input the occupant information (the number of occupants and the color information of the clothes of the specific occupant), the occupant information registration unit 12 inputs the occupant information input through the operation reception unit 11. By storing the information in the information storage unit 13, the occupant information is registered in the security device 102 (step S23). After that, the process proceeds to step S24.

When the registration of the occupant information is completed, the driver starts driving. After that, when arriving at the destination or waypoint, the occupants will get off the vehicle. The disembarkation detection unit 21 analyzes an image taken by a camera installed in the vehicle interior to determine whether or not the occupant has disembarked from the vehicle (step S24). Here, the determination in step S24 is repeated until the disembarkation detection unit 21 detects that the occupant has disembarked from the vehicle.

Then, when the disembarkation detection unit 21 detects that the occupant has disembarked from the vehicle, the disembarkation location detection unit 22 uses the current position information acquired from the current position detection device 201 and the map data acquired from the map data storage unit 202. Based on the above, the disembarkation detection unit 21 detects the location where the occupant's disembarkation is detected (step S25).

Next, the collation unit 16'determines whether or not the disembarkation location detected by the disembarkation location detection unit 22 is a predetermined location where the number of occupants may fluctuate (step S26). When it is determined that the disembarkation place is a place where the number of occupants may fluctuate, the collation unit 16'sets the number of occupants to be excluded from the collation (step S27). After that, the process proceeds to step S30.

If it is determined that the disembarkation location is not a location where the number of occupants may fluctuate, the collation unit 16'is a location where the disembarkation location may fluctuate the occupant's clothing. Whether or not it is determined (step S28). When it is determined that the disembarkation place is a place where the clothes of the occupants may fluctuate, the collation unit 16'sets the color information of the clothes to be out of the collation target (step S29). After that, the process proceeds to step S30.

After the occupant gets out of the vehicle and performs the desired desired action outside the vehicle, the occupant will re-enter the vehicle. The boarding detection unit 14 analyzes a photographed image input from a camera installed in the vehicle interior to determine whether or not a occupant has boarded the vehicle (step S30). Here, the determination in step S30 is repeated until the occupant's occupancy on the vehicle is detected by the occupancy detection unit 14.

When the occupant detection unit 14 detects that the occupant is on the vehicle, the occupant detection unit 15 analyzes the captured image input from the camera installed in the vehicle interior to obtain the number of occupants and the number of occupants. The color information of the clothes is detected (step S31). Then, the collation unit 16'matches the detection information output from the occupant detection unit 15 with the occupant information stored in the occupant information storage unit 13 (step S32), and the detection information and the occupant information match. Whether or not it is determined (step S33).

At this time, if the number of occupants is set to be excluded from the target of collation in step S27, the collation unit 16'only targets the color information of the occupant's clothes, and whether or not the detection information and the occupant information match. Is determined. Further, when the color information of the occupant's clothes is set to be excluded from the collation in step S29, the collation unit 16'only targets the number of occupants and determines whether the detection information and the occupant information match. To judge. Further, when the process of step S27 or step S29 has not been performed, the collating unit 16'targets both the number of occupants and the color information of the clothes, and determines whether or not the detection information and the occupant information match in both of them. judge.

Here, when it is determined that the detection information and the occupant information match, the collation unit 16'permits the authentication (step S34). In this case, the processing by the fraud prevention control unit 18 is not executed, and the vehicle can be used normally. As a result, the processing of the flowchart shown in FIG. 5 is completed.

On the other hand, if it is determined that the detection information and the occupant information do not match, the collation unit 16'disallows authentication (step S35). In this case, the fraud prevention control unit 18'executes the fraud prevention process (step S36). As a result, the processing of the flowchart shown in FIG. 5 is completed.

As described in detail above, in the second embodiment, occupant information including the number of occupants riding in the vehicle and the characteristics of at least one of the occupants on the day of boarding is stored in the occupant information storage unit 13 in advance. Keep it. Then, when the occupant's disembarkation from the vehicle is detected by the disembarkation detection unit 21, the number of occupants and the characteristics of the occupant's boarding day are collated according to the disembarkation location detected by the disembarkation location detection unit 22. Decide whether to target. After that, when the occupant's boarding on the vehicle is detected by the occupant detection unit 14, the collation unit 16'stores the detection information regarding the number of occupants and the characteristic items set as the collation target, and the occupant information storage. Of the occupant information stored in the unit 13, the occupant information set as the collation target is collated, and when it is determined that the detection information and the occupant information do not match, the authentication is disallowed.

According to the second embodiment configured in this way, in principle, the collation unit uses two pieces of information, that is, the number of occupants riding in the vehicle and the characteristics of at least one of the occupants on the day of boarding. Matching by 16'is performed. The number of occupants and the characteristics of the occupants on the day of boarding are information that can fluctuate depending on the time when the vehicle goes out, and since two types of information are used, this information is used by a third party who intends to use the vehicle illegally. It becomes difficult to match with. Thereby, according to the second embodiment, it is possible to effectively prevent the unauthorized use of the vehicle on the go.

Further, in the second embodiment, depending on the place where the occupant gets off, when the occupant subsequently gets on the vehicle, only the information of either the number of occupants who get on the vehicle or the characteristics of the day of boarding is used. The collation unit 16'performs the collation. This allows the vehicle to continue to be used as usual, even if either the number of occupants or the clothing of the legitimate occupants changes at the place of disembarkation.

It should be noted that the modification shown in FIG. 3 can also be applied to the second embodiment.

In the first and second embodiments, the occupant information storage unit 13 has described an example in which the number of occupants and the characteristics of the occupant on the day of boarding are stored as occupant information. Attribute information may be stored. The occupant's attribute information is information that can be discriminated by analyzing an image taken by the camera. For example, gender and body shape are applicable.

In this case, the occupant detection units 15 and 15'detect the number of occupants, features and attributes when the occupant's occupancy is detected by the occupant detection unit 14. The collation units 16 and 16'collate the detection information input from the occupant detection units 15 and 15'with the occupant information stored in the occupant information storage unit 13, and determine the number of occupants and the characteristics of the occupant on the day of boarding. If at least one of the items and attributes does not match, the authentication is not permitted.

Further, in the first and second embodiments, an example in which the color information of the clothes is used as a feature item on the day of boarding of the occupant has been described, but the pattern information is used instead of or in addition to the color information. May be good.

In addition, the first and second embodiments are merely examples of embodiment of the present invention, and the technical scope of the present invention should not be interpreted in a limited manner by these. It is something that does not become. That is, the present invention can be implemented in various forms without departing from its gist or its main features.
