  The present invention has been made in view of the above-described problems of the prior art. By performing fingerprint authentication in a security device, the setting of various devices of the security device can be permitted only to a specific person. With the goal.

  In the present invention, means for solving the above-described problems are configured as follows. That is, a security device configured to allow only a specific person to set various devices, and a fingerprint reading unit that reads a fingerprint of a person who is to perform various device settings, and a pre-registered fingerprint The fingerprint information storage means for storing the information, and the fingerprint information read by the fingerprint reading means and the fingerprint information stored in the fingerprint information storage means are collated and stored in the fingerprint information storage means Collation processing means for performing fingerprint authentication for determining whether or not there is information that matches the fingerprint information read by the fingerprint reading means in the fingerprint information that is present, and the result of fingerprint authentication by the collation processing means If there is a match, the person who wants to set up the various devices can set the various devices. If there is no match, the person Characterized in that it impossible settings.

  According to such a configuration, as a result of fingerprint authentication, only the owner (specific person) of a specific fingerprint registered in advance succeeds in the fingerprint authentication, and only the person is permitted to set various devices of the security device. The On the other hand, setting of various devices of the security device is prohibited for a fingerprint owner (a person other than a specific person) who is not registered in advance. Thus, various devices can be set up only after successful fingerprint authentication. Therefore, only a specific person can set various devices of the security device. Then, it is possible to prevent a person other than the specific person from setting various devices without the knowledge of the specific person, thereby improving the reliability of the security device. For example, a setting that prevents the security function of the security device from working at all by changing the sensitivity setting of the sensor and the setting of whether to use the sensor, etc., by setting operations such as a remote control to a person other than a specific person Can be prevented.

  Furthermore, when the settings of various devices in the security device are set to the optimum settings, it is impossible for a person other than a specific person to change the optimum settings, so the security device can be used with peace of mind. .

  Here, when the number of times the fingerprint authentication by the collation processing unit has failed (NG number) reaches a predetermined number, the collation processing unit reads the fingerprint read by the fingerprint reading unit until a predetermined time elapses. You may make it prohibit reception of information.

  As a result, even if a person other than a specific person tries to set up various devices in the security device, he / she wastes time for a predetermined time during which the reception of fingerprint information is prohibited. The setting is given up. On the other hand, when the predetermined time has elapsed, the prohibition of accepting fingerprint information is lifted, and the fingerprint can be read again. Therefore, even if the fingerprint authentication has failed a predetermined number of times, if the user waits for the predetermined time, the fingerprint can be read again to set various devices.

  Further, the fingerprint reading means, the fingerprint information storage means, and the collation processing means can be provided in a setting operation means (for example, a remote controller) for performing setting operations of various devices. As described above, by incorporating the fingerprint reading unit, the fingerprint information storage unit, and the collation processing unit in the setting operation unit, it is possible to perform fingerprint authentication in the setting operation unit. If the fingerprint authentication is successful, the setting operation of the various devices can be performed as it is using the setting operation means, and the convenience can be improved.

  The security apparatus of the present invention further comprises setting information storage means for storing information related to the settings of the various devices in association with fingerprint information stored in the fingerprint information storage means, and the verification processing means If there is a match as a result of the fingerprint authentication, various types corresponding to the fingerprint information read by the fingerprint reading unit based on the information on the settings of the various devices stored in the setting information storage unit A device setting process is performed.

  According to such a configuration, when performing various device settings of the security device, for example, if fingerprint authentication is successful without performing a setting operation using a setting operation unit such as a remote controller, the settings of the various devices are This is automatically performed based on information related to settings of various devices stored in the setting information storage means. As described above, since the setting processing of the various devices of the security device is automatically performed in accordance with the fingerprint information, the various devices can be set easily and quickly. In addition, if the settings of various devices that are optimal for a specific person are stored in the setting information storage means, the settings of the various devices can be immediately changed to the optimal settings, and the optimal settings are stored. There is no need to keep it.

  The setting information storage means can store a plurality of pieces of information related to settings of various devices stored in association with fingerprint information. Here, the information related to the settings of various devices stored in plural may correspond to information of fingerprints of different persons, or may correspond to information of fingerprints of different fingers of the same person. Also good. If information related to the settings of various devices is associated with the information of fingerprints of different people, it is possible to store various device settings that are optimal for a specific person. In addition, if information on settings of various devices is associated with information on fingerprints of different fingers of the same person, the settings of the various devices can be used properly according to the surrounding environment and the like.

  Since the present invention is configured as described above, as a result of fingerprint authentication, only the owner (specific person) of a specific fingerprint registered in advance succeeds in the fingerprint authentication. Device settings are allowed. On the other hand, setting of various devices of the security device is prohibited for a fingerprint owner (a person other than a specific person) who is not registered in advance. Thus, various devices can be set up only after successful fingerprint authentication. Therefore, only a specific person can set various devices of the security device. Then, it is possible to prevent a person other than the specific person from setting various devices without the knowledge of the specific person, thereby improving the reliability of the security device.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. In addition, the following embodiment is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not.

  Below, the example applied to the security device for vehicle antitheft (vehicle security device) about embodiment of this invention is demonstrated. The vehicle security device of this example is configured so that only a specific person can set various devices in the vehicle security device. However, as long as various devices are set in the security device, the device is not limited to the vehicle security device, and is similarly applied to a security device for preventing a suspicious person from entering the building or for other purposes. Can be applied.

  First, a first example of a vehicle security device will be described with reference to FIGS. 1 and 2.

  As shown in FIG. 1, the vehicular security device includes a fingerprint reading sensor 10, a fingerprint information storage unit 20, a verification processing unit 30, an LED 40, a setting processing unit 50, a remote controller 60, and various devices 70 and 70 to be set. , ... are provided. In addition, the vehicle security device is provided with devices that are not the target of setting in addition to the devices 70, 70,.

  The fingerprint reading sensor 10 is provided for reading a fingerprint of a person who wants to set various devices 70, 70,... In the vehicle security device. A person who wants to set the various devices 70, 70,... Causes the fingerprint reading sensor 10 to read a fingerprint for fingerprint authentication. The fingerprint information read by the fingerprint reading sensor 10 is sent to the verification processing unit 30. As the fingerprint reading sensor 10, for example, a capacitance type sensor can be used, but other than this, a pressure type sensor, an optical sensor, a conductive sensor, and a thermal sensor may be used. . Also, a method of pressing a finger or a method of sliding may be used.

  The fingerprint information storage unit 20 stores fingerprint information registered in advance. The fingerprint information storage unit 20 is configured as, for example, a nonvolatile semiconductor storage device such as an EPROM. Thus, by using the fingerprint information storage unit 20 as a non-volatile semiconductor storage device, the stored fingerprint information can be reliably stored without being lost even if power is not supplied. The security of the fingerprint can be improved by encrypting the fingerprint information stored in the fingerprint information storage unit 20. The fingerprint information can be encrypted by, for example, a checksum method, null point control, data conversion using a mathematical expression, or the like.

  The fingerprint information storage unit 20 can store information of a plurality of fingerprints. Therefore, in addition to the information of the fingerprint of the original owner of the vehicle, a person other than the owner who is permitted to set various devices 70, 70,... If there is a person's family, a company employee, etc.), the fingerprint information of the person can be stored. The information on the fingerprint of the original owner of the vehicle may be registered in advance when the vehicle is purchased. Moreover, what is necessary is just to register the fingerprint of the person other than an owner who was permitted to set the various devices 70, 70,... If the person who is permitted to set the various devices 70, 70,... Of the vehicle security device for the vehicle is not permitted to make subsequent settings, the information on the fingerprint of the person is stored as needed. It should be deleted.

  The collation processing unit 30 collates the fingerprint information read by the fingerprint reading sensor 10 with the fingerprint information stored in the fingerprint information storage unit 20, and the fingerprint information stored in the fingerprint information storage unit 20. The fingerprint authentication process is performed to determine whether or not there is a match with the fingerprint information read by the fingerprint reading sensor 10. If there is a match as a result of such fingerprint authentication processing, a setting operation permission signal is output to the setting processing unit 50. Conversely, if there is no match, fingerprint authentication is performed. A process of counting the number of times of failure (referred to as “NG times”) is performed.

  Moreover, the collation process part 30 performs the process which determines whether the number of NG reached the predetermined number. Then, when the number of NG times reaches a predetermined number, a process of prohibiting acceptance of fingerprint information read by the fingerprint reading sensor 10 is performed until a predetermined time elapses. The verification processing unit 30 includes an internal timer. Details of each processing in the verification processing unit 30 will be described later.

  The LED 40 is provided to notify a person who has performed fingerprint reading that fingerprint authentication has failed when fingerprint authentication, which will be described later, has failed. When the LED 40 is turned on, the fingerprint reading sensor 10 prompts the user to read the fingerprint again.

  The setting processing unit 50 performs setting processing of various devices 70, 70,... In the vehicle security device in accordance with a setting operation of the remote controller 60 described later. When the setting operation permission signal is input from the collation processing unit 30, the setting processing unit 50 sets various devices 70, 70,... According to the setting operation of the setting operation button 64 of the remote controller 60 only in this case. A state where processing can be performed (setting processing enabled state) is set. In other words, if the setting operation permission signal is not input from the collation processing unit 30, the setting processing unit 50 does not enter the setting process enabled state. When the setting processing unit 50 is ready for setting processing, the setting processing of the various devices 70, 70,... Is completed by the setting operation of the predetermined setting operation button 64, or when a predetermined time elapses. The setting process enabled state is canceled and the original state is restored. The setting processing unit 50 includes an internal timer.

  Here, the various devices 70, 70,... Of the vehicle security device include, for example, a human body sensor that detects the approach of the human body, a tilt sensor that detects the tilt of the vehicle body, a vibration sensor that detects the vibration of the vehicle body, and a door. Sensors such as current sensors that detect the opening of doors, door lock devices for unlocking / locking doors, engine starting devices for starting engines, and security activation (stolen vehicles with the above-mentioned sensors Alarms such as a horn that emits a warning sound when a person is detected), an illuminator such as an LED that lights or flashes during security operation, or a person who attempts to steal a vehicle during security operation There is a communication device or the like that informs the vehicle owner or the like. Further, as settings that can be made by the user of these various devices 70, 70,..., For example, the sensitivity setting as described above and the setting as to whether or not to use the sensor as described above are used. , Setting of alarm sound volume of alarm device, setting of sound color of that alarm sound, setting of whether to use emergency alarm to sound alarm sound of alarm device remotely from remote place, when security is activated There are settings such as whether to turn on or blink the illuminator, whether to notify the vehicle owner, etc. that a person who tries to steal the vehicle is detected by a communication device during security operation .

  In addition, when the setting operation permission signal is input from the verification processing unit 30, the setting processing unit 50 sends a setting operation enable signal to the remote controller 60. As a result, the LED 63 of the remote controller 60 is lit and blinks in a predetermined light emission pattern, so that the person who has performed fingerprint authentication is notified that the setting operation of the various devices 70, 70,. Details of each process in the setting processing unit 50 will be described later.

  The remote controller 60 is provided as a setting operation means for performing a setting operation of various devices 70, 70,... In the vehicle security device. The remote controller 60 is provided with a control unit 61, a transmission / reception unit 62, an LED 63, a setting operation button 64, and a memory 65.

  The control unit 61 manages various processes in the remote controller 60. The transmission / reception unit 62 can transmit and receive signals to and from the setting processing unit 50 using infrared rays or the like. Various signals are received from the setting processing unit 50 via the transmission / reception unit 62, while various signals are transmitted to the setting processing unit 50.

  The LED 63 is provided for notifying a person who wants to perform a setting operation of the various devices 70, 70,. In this example, various types of information are notified by a light emission pattern in which the LED 63 is lit or blinking. The various information notified by the light emission pattern of the LED 63 represents, for example, information indicating that the setting operation of the various devices 70, 70,... Is possible, and the device 70 to be set by the remote controller 60. Information indicating the setting after the setting operation of the target device 70, information indicating that the setting processing of the various devices 70, 70,... Has been completed, and the setting operation of the remote controller 60 are incorrect. There is information indicating that the user is prompted to perform a setting operation. The light emission pattern in which the LED 63 is lit / flashing is stored in the memory 65.

  When notifying various information, the light emission pattern of the memory 65 is read by the control unit 61, and the LED 63 is lit and blinks with the read light emission pattern. The number of LEDs 63 is not particularly limited, and may be one or plural, and in the case of plural, ones having different emission colors can be used. Instead of the LED 63, a display such as a liquid crystal panel may be provided to display various information as character information.

  A plurality of setting operation buttons 64 are provided on the remote control 60. The plurality of setting operation buttons 64 are used when performing a setting operation of various devices 70, 70,. When a person who wants to perform a setting operation on various devices 70, 70,... Performs a setting operation on a predetermined setting operation button 64, a signal corresponding to the setting operation is sent from the transmission / reception unit 62 to the setting processing unit 50. . Thereby, the setting processing of the various devices 70, 70,... According to the signal input by the setting processing unit 50 is performed. Here, as described above, after the fingerprint authentication is successful and the LED 63 is lit and blinks in a predetermined light emission pattern, the predetermined setting is associated with the setting processing of the various devices 70, 70,. When the setting operation of the setting operation button 64 that matches the setting operation pattern of the operation buttons 64 (the order of setting operation of the plurality of setting operation buttons 64) is performed, a signal corresponding to the setting operation is transmitted from the transmission / reception unit 62 to the setting processing unit. 50 to be sent. The setting operation pattern of the setting operation button 64 includes a pattern for determining the device 70 to be set and a pattern for determining the setting of the device 70 to be set. The setting operation pattern of the setting operation button 64 associated with the setting processing of the various devices 70, 70,... Is stored in the memory 65.

  Whether or not the setting operation of the setting operation button 64 performed by a person who performs the setting operation of the various devices 70, 70,... Matches the setting operation pattern stored in the memory 65. This determination is performed by the control unit 61. On the other hand, when the setting operation of the setting operation button 64 that does not match the setting operation pattern of the setting operation button 64 associated with the setting processing of the various devices 70, 70,. Lights and blinks in a pattern to notify the person who has performed the setting operation of the setting operation button 64 that the setting operation is incorrect and prompts the user to perform the setting operation again.

  As described above, when a liquid crystal panel is provided in place of the LED 63, a setting operation unit that replaces the setting operation button 64 can be provided on the liquid crystal panel. The setting operation unit of the liquid crystal panel displays, for example, the device 70 that can be the target of the setting process, displays the portion that determines the target device 70, and the settings that can be set for the target device 70, This is a part for determining the setting of the device 70.

  In the vehicular security device configured as described above, by performing fingerprint authentication, only a specific person is allowed to perform setting operations of the various devices 70, 70,... In the vehicular security device. Yes. Hereinafter, the procedure of the process in the vehicle security device when performing the setting operation of the various devices 70, 70,... Will be described with reference to the flowchart of FIG.

  First, when a fingerprint reading operation is performed by the fingerprint reading sensor 10 (step S1), that is, a person who wants to perform a setting operation of various devices 70, 70,... Is read, the fingerprint information read by the fingerprint reading sensor 10 is sent to the verification processing unit 30.

  When the collation processing unit 30 acquires the information about the fingerprint read by the fingerprint reading sensor 10 (step S2), the collation processing unit 30 then performs a fingerprint authentication process (step S3). Specifically, the fingerprint information read by the fingerprint reading sensor 10 is collated with the fingerprint information stored in the fingerprint information storage unit 20, and the fingerprint information stored in the fingerprint information storage unit 20 is checked. It is determined whether or not there is any that matches the fingerprint information read by the fingerprint reading sensor 10.

  If there is no match as a result of such fingerprint authentication processing, the verification processing unit 30 determines that fingerprint authentication has failed, and counts the number of NG times (step S4). Here, a process of adding “1” to the current NG count is performed. In this case, since it is the first fingerprint reading operation from the standby state, “1” is counted as the number of NG times.

  Next, the collation processing unit 30 determines whether or not the number of NG has reached a predetermined number (step S5). As a result, when the number of NG times has not reached the predetermined number, the collation processing unit 30 urges the person who has read the fingerprint to read the fingerprint again by the fingerprint reading sensor 10 through the LED 40 for notification. After (step S6), the fingerprint information read again by the fingerprint reading sensor 10 is acquired (step S7), and the process proceeds to step S3. Then, the number of NG times reaches a predetermined number or, in the determination of step S3, the fingerprint information stored in the fingerprint information storage unit 20 matches the fingerprint information read again by the fingerprint reading sensor 10. Steps S6, S7, S3, S4, and S5 are repeated until there is something to do.

  On the other hand, when the number of NG times reaches a predetermined number, the collation processing unit 30 starts an internal timer (step S8). Then, until a predetermined time elapses, the collation processing unit 30 prohibits (rejects) reception of the fingerprint information read by the fingerprint reading sensor 10 (steps S9 and S10). That is, fingerprint information is not input to the verification processing unit 30 for a predetermined time. Therefore, processing such as fingerprint authentication in step S3 is not performed. Then, when the predetermined time has elapsed, the internal timer is stopped, the time count of the internal timer is reset, the number of NG times is further reset, and this control is terminated.

  On the other hand, if there is a match as a result of the fingerprint authentication process in step S3, the collation processing unit 30 determines that the fingerprint authentication is successful, and sends a setting operation permission signal to the setting processing unit 50 (step S11). . In this case, the person who performed the fingerprint authentication is permitted to set the various devices 70, 70,... Of the vehicle security device of the vehicle that is the original owner of the vehicle or other than the owner. If it is an authorized person (referred to as “owner or the like”), the fingerprint authentication is successful and a setting operation permission signal is sent to the setting processing unit 50.

  Next, when receiving the setting operation permission signal from the collation processing unit 30, the setting processing unit 50 performs setting processing of various devices 70, 70,... According to the setting operation of the setting operation button 64 of the remote controller 60. (Step S12), a setting operation enable signal is transmitted to the remote controller 60, and an internal timer is started (step S13). When this setting operation enable signal is received by the remote controller 60 via the transmission / reception unit 62, the LED 63 of the remote controller 60 is lit and blinks in a predetermined light emission pattern, and various devices 70, 70 are provided to those who have performed fingerprint authentication. ,... Is notified that the setting operation is possible.

  Thereby, the setting operation of the setting operation button 64 of the remote control 60 can be performed by a person who has performed fingerprint authentication (a person who wants to perform setting operation of various devices 70, 70,...). When a setting operation of a predetermined setting operation button 64 is performed, a signal corresponding to the setting operation is transmitted from the transmission / reception unit 62 to the setting processing unit 50. At this time, when the setting operation of the setting operation button 64 that matches the setting operation pattern of the setting operation button 64 associated with the setting processing of the various devices 70, 70,. A signal corresponding to the setting operation is transmitted from the transmission / reception unit 62 to the setting processing unit 50.

  Next, the setting processing unit 50 determines whether or not a signal corresponding to the setting operation of the setting operation button 64 of the remote controller 60 has been received within a predetermined time (steps S14 and S15). In other words, a setting operation of a predetermined setting operation button 64 is performed by a person who performs a setting operation of the various devices 70, 70,..., And a signal corresponding to the setting operation is transmitted from the transmission / reception unit 62 to the setting processing unit 50. It is determined whether or not it has been sent. As a result, when a signal corresponding to the setting operation of the setting operation button 64 of the remote controller 60 is received within a predetermined time, the setting processing unit 50 sets various devices 70, 70,... According to the signal. Processing is performed (step S16). Also, stop the internal timer and reset the time count of the internal timer. Thereby, the setting processing of the various devices 70, 70,... According to the setting operation of the setting operation button 64 of the remote controller 60 is performed.

  Thereafter, the setting processing unit 50 releases the above-described setting process enabled state and returns to the original state. Then, when the setting processing completion signal is transmitted from the setting processing unit 50 to the remote control 60 and this signal is received by the remote control 60 via the transmission / reception unit 62, the LED 63 of the remote control 60 is lit and blinks in a predetermined light emission pattern. The person who performed the setting operation is notified that the setting processing of the various devices 70, 70,... Has been completed (step S17). On the other hand, if the signal corresponding to the setting operation of the setting operation button 64 of the remote controller 60 is not received within the predetermined time, the setting processing unit 50 stops the internal timer, resets the time measurement of the internal timer, and The setting process enabled state is canceled and the original state is restored (step S18), and this control is terminated.

  According to the vehicle security device of this example, as described above, as a result of the fingerprint authentication, only the owner of the specific fingerprint registered in advance, that is, the owner of the vehicle has succeeded in the fingerprint authentication. Only the setting operation of the various devices 70, 70,... Of the vehicle security device is permitted. On the other hand, setting operations of the various devices 70, 70,... Of the vehicle security device are prohibited for owners of fingerprints not registered in advance, that is, persons other than the owner of the vehicle. Yes. In this way, the various devices 70, 70,... Can be set only after successful fingerprint authentication. Therefore, only a specific person such as the owner of the vehicle can perform the setting operation of the various devices 70, 70,. Further, it is possible to prevent other persons from performing setting operations of the various devices 70, 70,... Without the owner of the vehicle or the like knowing the reliability of the vehicle security device. Can be improved. For example, the security function of the vehicular security device does not work at all by changing the sensitivity setting of the sensor, the setting of whether to use the sensor, or the like by a setting operation of the remote controller 60 to a person other than the owner or the like. Can be prevented.

  Furthermore, when the settings of the various devices 70, 70,... In the vehicular security device are set to the optimum settings, it is impossible for a person other than the owner or the like to change the optimum settings. Keep in mind that you can use the vehicle security device.

  Further, as described above, when the number of NGs reaches a predetermined number, the fingerprint information read by the fingerprint reading sensor 10 is prohibited from being accepted for a predetermined time so that fingerprint authentication is not performed. ing. Note that the fingerprint reading sensor 10 may not perform the fingerprint reading operation for a predetermined time.

  As a result, even if a person other than the vehicle owner or the like tries to set the various devices 70, 70,... In the vehicle security device, the fingerprint information is prohibited from being accepted for a predetermined time. And, by making time uselessly, the setting operation is given up. On the other hand, when the predetermined time has elapsed, the prohibition of accepting fingerprint information is lifted, and the fingerprint can be read again. Therefore, even if the vehicle owner or the like has failed the fingerprint authentication a predetermined number of times, if the user waits for the predetermined time, the fingerprint can be read again and the setting operation of the various devices 70, 70,. .

  Here, the above-described fingerprint reading sensor, collation processing unit, and the like can be incorporated into the remote control 60. For example, as shown in FIG. 3, the fingerprint reading sensor 66 can be provided in the remote controller 60. In this case, the fingerprint information read by the fingerprint reading sensor 66 is transmitted to the verification processing unit 30 via the transmission / reception unit 62 of the remote controller 60. Further, by turning on and blinking the LED 63 of the remote controller 60 in a predetermined light emission pattern, when fingerprint authentication fails, the person who performed fingerprint reading is visually urged to read the fingerprint again by the fingerprint reading sensor 66. be able to. In this case, it is not necessary to provide a separate LED for notification.

  For example, as shown in FIG. 4, the fingerprint reading sensor 66 and the fingerprint information storage unit 67 can be incorporated in the remote controller 60 so that the above-described fingerprint authentication process can be performed by the remote controller 60. In this case, the control unit 61 of the remote controller 60 also serves as the matching processing unit 30 in the above-described example. That is, the control unit 61 of the remote controller 60 also functions as the collation processing unit in the above-described example.

  Specifically, the control unit 61 collates the fingerprint information read by the fingerprint reading sensor 66 with the fingerprint information stored in the fingerprint information storage unit 67 and stores the fingerprint information in the fingerprint information storage unit 67. Fingerprint authentication is performed to determine whether there is any fingerprint information that matches the fingerprint information read by the fingerprint reading sensor 66. If there is a match as a result of fingerprint authentication, a setting operation permission signal is transmitted to the setting processing unit 50 via the transmission / reception unit 62. Conversely, if there is no match, NG is determined. Count the number of times. Further, the control unit 61 determines whether or not the number of NGs has reached a predetermined number. When the number of NGs reaches a predetermined number, the fingerprint read by the fingerprint reading sensor 66 until a predetermined time has elapsed. Prohibit (reject) the reception of information. When the number of NGs reaches a predetermined number, transmission / reception with the setting processing unit 50 may be prohibited.

  As described above, fingerprint authentication can be performed by the control unit 61, the fingerprint reading sensor 66, and the fingerprint information storage unit 67 incorporated in the remote controller 60. If the fingerprint authentication is successful, it is possible to continue the setting operation of the various devices 70, 70,... Using the remote controller 60 as it is, and the convenience can be improved.

  Next, a second example of the vehicle security device will be described.

  In the first example described above, in order to set the various devices 70, 70,..., After the fingerprint authentication is successful, a setting operation corresponding to the setting process of the various devices 70, 70,. 60. On the other hand, in the second example, when setting the various devices 70, 70,..., The setting operation by the remote controller 60 in the first example as described above is unnecessary. Hereinafter, a specific description will be given with reference to FIGS. 5, 6, and 7. In addition, about the part of the structure similar to the vehicle security apparatus of a 1st example, the same number as the case of a 1st example is attached | subjected and detailed description is abbreviate | omitted.

  As shown in FIG. 5, the vehicle security device of this example includes a fingerprint reading sensor 10, a fingerprint information storage unit 20, a verification processing unit 130, an LED 40, a setting processing unit 150, various devices 70 subject to setting operations, 70,..., A setting information storage unit 180, and an LED 190.

  The collation processing unit 130 sends the information of the fingerprint read by the fingerprint reading sensor 10 to the setting processing unit 150 when there is a match as a result of the fingerprint authentication process. It differs mainly from the part 30. After successful fingerprint authentication, the setting processing unit 150 receives the information of the fingerprint read by the fingerprint reading sensor 10 from the collation processing unit 130 and stores the vehicle security device stored in the setting information storage unit 180. In the first example, the setting processing of the various devices 70, 70,... In the vehicular security device is performed based on the information (setting information table 181) regarding the settings of the various devices 70, 70,. Mainly different from the setting processing unit 50. Details of each processing in the verification processing unit 130 and the setting processing unit 150 will be described later. The LED 190 is provided to notify the completion of the setting process when the setting process of various devices 70, 70,.

  In the setting information storage unit 180, information related to settings of the various devices 70, 70,... Of the vehicle security device is stored in advance in association with fingerprint information. Here, the fingerprint information associated with the information related to the settings of the various devices 70, 70,... Of the vehicle security device is the same information as the fingerprint information stored in the fingerprint information storage unit 20. Like the fingerprint information storage unit 20, the setting information storage unit 180 is configured as a nonvolatile semiconductor storage device such as an EPROM. Note that the fingerprint information stored in the setting information storage unit 180 may be encrypted.

  The information related to the settings of the various devices 70, 70,... Of the vehicle security device is stored together with the corresponding fingerprint information, for example, as a setting information table 181 as shown in FIG. The setting information table 181 is referred to when the setting processing unit 150 performs setting processing of various devices 70, 70,. In this setting information table 181, it is registered which setting processing of various devices 70, 70,... Of the vehicle security device is performed based on the fingerprint information sent to the setting processing unit 150. .

  Specifically, as illustrated in FIG. 6, the setting information table 181 includes columns of “fingerprint”, “device”, and “setting”, and relates to settings of various devices 70, 70,. Information is registered in association with fingerprint information. In addition, it is necessary to register in advance fingerprint information and information related to the settings of the various devices 70, 70,... Associated with the fingerprint information. The setting operation means such as the remote controller 60 in the first example is used. The fingerprint information and the information related to the settings of the various devices 70, 70,... Associated with the fingerprint information are registered, updated, or deleted as needed. That's fine.

  Next, a processing procedure in the vehicle security device when setting the various devices 70, 70,... Will be described with reference to the flowchart of FIG.

  First, when a fingerprint reading operation is performed by the fingerprint reading sensor 10 (step S101), that is, a person who performs setting operation of various devices 70, 70,... Is read, the fingerprint information read by the fingerprint reading sensor 10 is sent to the verification processing unit 130.

  When the collation processing unit 130 acquires the fingerprint information read by the fingerprint reading sensor 10 (step S102), the collation processing unit 130 performs fingerprint authentication processing (step S103). Specifically, the fingerprint information read by the fingerprint reading sensor 10 is collated with the fingerprint information stored in the fingerprint information storage unit 20, and the fingerprint information stored in the fingerprint information storage unit 20 is checked. It is determined whether or not there is any that matches the fingerprint information read by the fingerprint reading sensor 10.

  If there is no match as a result of such fingerprint authentication processing, the collation processing unit 130 determines that fingerprint authentication has failed and counts the number of NG times (step S104). Here, a process of adding “1” to the current NG count is performed. In this case, since it is the first fingerprint reading operation from the standby state, “1” is counted as the number of NG times.

  Next, the verification processing unit 130 determines whether or not the number of NG times has reached a predetermined number (step S105). As a result, when the number of NG times has not reached the predetermined number, the collation processing unit 130 urges the person who has read the fingerprint to read the fingerprint again by the fingerprint reading sensor 10 through the LED 40 for notification. After (step S106), the fingerprint information read again by the fingerprint reading sensor 10 is acquired (step S107), and the process proceeds to step S103. Then, the number of NG times reaches a predetermined number, or, in the determination in step S103, the fingerprint information stored in the fingerprint information storage unit 20 matches the fingerprint information read again by the fingerprint reading sensor 10. Steps S106, S107, S103, S104, and S105 are repeated until there is something to do.

  On the other hand, when the number of NG times reaches a predetermined number, the collation processing unit 130 starts an internal timer (step S108). Then, the collation processing unit 130 prohibits (rejects) the reception of the fingerprint information read by the fingerprint reading sensor 10 until a predetermined time has elapsed (steps S109 and S110). That is, fingerprint information is not input to the verification processing unit 130 for a predetermined time. Accordingly, processing such as fingerprint authentication in step S103 is not performed. Then, when the predetermined time has elapsed, the internal timer is stopped, the time count of the internal timer is reset, the number of NG times is further reset, and this control is terminated.

  On the other hand, if there is a match as a result of the fingerprint authentication process in step S103, the collation processing unit 130 determines that the fingerprint authentication is successful, and sets the fingerprint information read by the fingerprint reading sensor 10 as a setting processing unit. 150 (step S111). In this case, if the person who performed the fingerprint authentication is a specific person such as the owner of the vehicle, the fingerprint authentication is successful, and the fingerprint information is sent to the setting processing unit 150.

  Next, when the setting processing unit 150 receives the fingerprint information read by the fingerprint reading sensor 10 from the collation processing unit 130, the setting processing unit 150 refers to the setting information table 181 stored in the setting information storage unit 180 to read the fingerprint. The settings of various devices 70, 70,... Corresponding to the fingerprint information read by the sensor 10 are read (step S112). And the setting process part 150 performs the setting process of various apparatus 70,70, ... according to the content of the setting of various apparatus 70,70, ... read at this time (step S113). As described above, the setting processing of the various devices 70, 70,... Is performed based on the information related to the settings of the various devices 70, 70,. When the setting processing of the various devices 70, 70,... Is completed, the LED 190 is turned on to notify the completion of the setting processing (step S114).

  According to the vehicle security device of this example, in addition to the operational effects of the first example described above, the following operational effects are also achieved. When setting the various devices 70, 70,... Of the vehicle security device, if the fingerprint authentication is successful without performing the setting operation by the remote controller 60 in the first example as described above, the various devices 70, 70,. Are automatically set based on information relating to the settings of the various devices 70, 70,... Stored in the setting information storage unit 180. That is, when the fingerprint authentication is successful, the setting processing of various devices 70, 70,... Corresponding to the fingerprint information read by the fingerprint reading sensor 10 is automatically performed.

  As described above, since the setting processing of the various devices 70, 70,... Of the vehicle security device is automatically performed in accordance with the fingerprint information, the various devices 70, 70,. This can be done quickly. If the settings of the various devices 70, 70,... That are optimal for the vehicle owner or the like are stored in the setting information storage unit 180, the settings of the various devices 70, 70,. It is possible to change the setting, and it is not necessary to store the optimum setting. For example, when there are a plurality of vehicle owners and the like, and the setting of the various devices 70, 70,... That is optimal for each is stored in the setting information storage unit 180, the various devices 70, 70,. If the fingerprint reading sensor 10 reads fingerprint information even if the setting is changed without knowing and is different from the optimum setting, the settings of the various devices 70, 70,... Can be returned to. Thereby, the security device for vehicles can be used in peace.

  Here, the setting information storage unit 180 can store a plurality of pieces of information related to settings of the various devices 70, 70,... Associated with the fingerprint information. The information related to the settings of the various devices 70, 70,... Stored may correspond to the information of fingerprints of different persons, or may correspond to the information of fingerprints of different fingers of the same person. It may be a thing. When the information on the settings of the various devices 70, 70,... Is associated with the information of fingerprints of different persons, the settings of the various devices 70, 70,. It becomes possible to leave. For example, in addition to the information related to the settings of the various devices 70, 70,... Corresponding to the fingerprint information of the original owner of the vehicle, the various devices 70, 70 of the vehicle security device for the vehicle other than the owner. ,..., If there is a person who is permitted to set (for example, the owner's family, company employee, etc.), setting of various devices 70, 70,... Corresponding to the fingerprint information of the person Can be stored. On the other hand, if the information related to the settings of the various devices 70, 70,... Is associated with the fingerprint information of different fingers of the same person, the settings of the various devices 70, 70,. It becomes possible. For example, information related to the settings of the various daytime devices 70, 70,... Is stored in correspondence with the information of the thumb fingerprint, or information related to the settings of the various nighttime devices 70, 70,. .., Stored in correspondence with the fingerprint information of the middle finger, or stored in correspondence with the fingerprint information of the middle finger in the place where there is a lot of traffic. Can be stored in correspondence with the fingerprint information of the ring finger.

  In the above description, when the fingerprint authentication is successful, the fingerprint information read by the fingerprint reading sensor 10 is sent from the collation processing unit 130 to the setting processing unit 150. However, an identification symbol instead of the fingerprint information is used. May be sent. In this case, an identification symbol that replaces the fingerprint information is assigned to each fingerprint information stored in the fingerprint information storage unit 20, and further, each assigned identification symbol is assigned to the setting information storage unit 180. Information related to the settings of the various devices 70, 70,. When the fingerprint authentication is successful, the collation processing unit 130 reads the identification symbol corresponding to the fingerprint information read by the fingerprint reading sensor 10 from the fingerprint information storage unit 20 and sends it to the setting processing unit 150.

  In the above description, the fingerprint information storage unit 20 and the setting information storage unit 180 are configured as separate storage units, but may be configured as a single storage unit. In this case, if the setting information table 181 as shown in FIG. 6 is stored in the single storage means, fingerprint authentication can be performed using the fingerprint information of the setting information table 181. When the fingerprint authentication is successful, the setting information table 181 can be referenced to set various devices 70, 70,... Of the vehicle security device.
