For example, a user may input an authentication command through an input screen of the vehicle Bluetooth module 200 after getting into the vehicle 210 (at this time, it is assumed that the input screen can be executed even if the vehicle is not started). )

The mobile device 100 and one or more Bluetooth devices 300 periodically or non-periodically broadcast a beacon signal for Bluetooth communication (S421, S422). In this case, the one or more Bluetooth devices 300 may be, for example, any Bluetooth device such as a smart watch, Bluetooth earphone, or Bluetooth speaker possessed by the user.

The vehicle Bluetooth module 200 receives a beacon signal broadcast by the mobile device 100 and one or more Bluetooth devices 300 (S420) and extracts identification information therefrom (S430). The vehicle Bluetooth module 200 compares the extracted identification information with pre-stored identification information (S440), and if the two identification information are the same, it is possible to authenticate that a user possessing a Bluetooth device with the same identification information is a user with driving authority. (S450).

According to the above-described embodiment, the user can perform registration device registration (FIG. 4) and user authentication (FIG. 5) in various ways.

For example, when the user executes the steps of FIG. 4 and registers only the mobile device 100 as a registration device, the user carries the mobile device 100 and gets into the vehicle 210 and executes the steps of FIG. 5 to authenticate the user. can succeed in In an alternative embodiment, for example, the user may register the mobile device 100 and one Bluetooth device 300 (eg smart watch) as registration devices by executing the steps of FIG. 4, in which case the user may register the mobile device ( 100) and a smart watch, and after boarding the vehicle 210, if the steps of FIG. 5 are executed, user authentication may succeed.

As another example, for example, the user may register the mobile device 100, the smart watch, and the Bluetooth speaker pre-installed in the vehicle as registration devices by executing the steps of FIG. 4 . In this case, user authentication may be successful by carrying the mobile device 100 and the smart watch, getting into the vehicle 210, turning on the Bluetooth speaker, and executing the steps of FIG. 5 .

Fig. 6 is an exemplary flowchart of registering a Bluetooth device in a vehicle according to a third embodiment.

Referring to FIG. 6 , in step S510, the vehicle Bluetooth module 200 may receive a device registration command from the user.

Identification information of each Bluetooth device 100 or 300 is extracted from the beacon signal (S530). The vehicle Bluetooth module 200 may register the mobile device 100 and one or more Bluetooth devices 300 as registration devices for user authentication by storing the extracted identification information, for example, in a storage device within the module (S540). At this time, in step S540, the vehicle Bluetooth module 200 sets the number of devices actually used for user authentication among the registered devices ("number of authentication devices") and/or sets priority for the registered devices. can

Fig. 7 is an exemplary flowchart for authenticating a user in a vehicle according to a third embodiment.

Referring to FIG. 7 , in step S610, the vehicle Bluetooth module 200 may receive an authentication command from the user. For example, after a user gets into the vehicle 210, an authentication command may be input through an input screen of the Bluetooth module 200 for a vehicle.

The mobile device 100 and one or more Bluetooth devices 300 periodically or non-periodically broadcast a beacon signal for Bluetooth communication (S621, S622). In this case, the one or more Bluetooth devices 300 may be, for example, any Bluetooth device such as a smart watch, Bluetooth earphone, or Bluetooth speaker possessed by the user.

The vehicle Bluetooth module 200 receives a beacon signal broadcast by the mobile device 100 and one or more Bluetooth devices 300 (S620) and extracts identification information therefrom (S630). The vehicle Bluetooth module 200 compares the extracted identification information with pre-stored identification information (S640). At this time, when the number and/or priority of authentication devices is set in step S540 of FIG. 6, identification information comparison operation may be performed based on the set number and/or priority of authentication devices, and identification information comparison result When there is the same identification information, it is possible to authenticate that a user possessing a Bluetooth device having the same identification information is a user with driving authority (S650).

Now, an exemplary method for setting the number of authentication devices for a plurality of registration devices and/or setting priorities for registration devices (eg, S540 in FIG. 6) and performing user authentication using the same (eg, S540 in FIG. 7) S640) An exemplary method will be described with reference to FIGS. 8 to 10.

8 shows an exemplary embodiment of registering a Bluetooth device in a register of registered devices.

In this embodiment, the 'registered device list' is a mobile device by performing steps such as, for example, saving identification information in FIG. 2 (S140), storing identification information in FIG. 4 (S340), or setting (S540) in FIG. 6. (100) or a storage unit (eg, a memory or a storage device) of the vehicle Bluetooth module 200.

Referring to FIG. 8(a), it is assumed that four Bluetooth devices, that is, device A, device B, device C, and device D are registered in the registered device list 10. At this time, the information stored in the registered device list 10 includes, for example, identification information (eg, MAC address) corresponding to each device. In an alternative embodiment, identification information other than the MAC address may be included, and other information such as the name or registration date of each device may be included.

In one embodiment, the user may set the number of devices ('number of authentication devices') that the user actually uses for authentication with respect to devices registered in the registered device list. For example, the user may set the number of authentication devices through an input screen such as the application 110 of the mobile device 100 or the touch screen of the Bluetooth module 200 for a vehicle.

As an example, 4 Bluetooth devices are registered in the registration device list 10 in FIG. You can succeed.

As another example, when a user registers three Bluetooth devices (eg, a mobile phone, a Bluetooth earphone, and a smart watch) as registered devices in the registration device list 10 and sets the number of authentication devices to '2', the registered three User authentication can be successfully performed by carrying only two of the devices and boarding the vehicle. Accordingly, the security of user authentication is improved, and at the same time, user authentication is more simple and convenient.

In another embodiment, the user may set priorities for devices registered in the registered device list. The user may set the priority through an input screen such as the application 110 of the mobile device 100 or the touch screen of the Bluetooth module 200 for a vehicle. For example, in the embodiment of FIG. 8(a), when four Bluetooth devices are registered in the registration device list 10, the user can set the priority of device A, device B, device C, and device D in order.

When the number and priority of authentication devices are set in this way, in one embodiment, the mobile device 100 or the Bluetooth module 200 for a vehicle determines the reliability of user authentication (hereinafter referred to as 'authentication reliability') based on the set number and priority of authentication devices. Also referred to as) may be calculated and additional authentication may be further requested from the user accordingly.

For example, in the embodiments of FIGS. 8(a) to 8(c), four devices are registered in the registration device list 10, and the user sets the number of authentication devices to '2' and sets the priority to device A. , it is assumed that the B device, C device, and D device are set in order. 8(a) shows a case where a user carries device A and device B and gets into a vehicle. That is, in FIG. 8(a), 'O' is displayed next to A and B devices, and 'X' is displayed for C and D devices. In this case, the vehicle Bluetooth module 200 identified device A and device B by receiving the beacon signals of device A and device B and extracting identification information, and since the identified two devices have the first and second priority, The vehicle Bluetooth module 200 may determine, for example, authentication reliability as 'high', and may complete user authentication without requesting separate additional authentication.

As another example, FIG. 8(b) shows a case where the user has device B and device C and gets into a vehicle (ie, device B and device C are marked with 'O' in FIG. 8(b), and device A and Device D is marked with an 'X'). In this case, since the two identified devices are the second and third priority devices and the first priority device was not detected, the authentication reliability may be determined as 'medium' and an additional authentication procedure may be requested. At this time, as an additional authentication procedure, for example, a known authentication procedure such as requesting input of a password previously set by the user or requesting input of a previously registered fingerprint may be applied.

As another example, FIG. 8(c) shows a case where the user carries device C and device D and gets into a vehicle (i.e., device C and device D are marked as 'O' in FIG. 8(c) and device A and device B are marked with 'X'). In this case, since the two identified devices are the third and fourth priority devices and the first and second priority devices were not detected, the vehicle Bluetooth module 200 may determine the authentication reliability as 'low' and request, for example, an additional authentication procedure. there is. In this case, the additional authentication procedure may be the same as that of the 'medium' authentication reliability, but alternatively, two or more additional authentications may be requested or authentication with a higher level of difficulty may be requested.

In an embodiment, for example, the following criteria may be used as criteria for determining authentication reliability as 'high', 'medium', and 'low'.

(i) When the vehicle Bluetooth module 200 recognizes the first-order device, authentication reliability may be determined as 'high'. For example, in the embodiment of FIG. 8(a), when the vehicle Bluetooth module 200 recognizes device A, and recognizes only one more of the remaining devices (device B, device C, and device D), the authentication reliability is set to 'high'. ' can be judged.

(ii) When the vehicle Bluetooth module 200 does not recognize the first-priority device, but recognizes at least one registration device having a priority within the number of authentication devices, authentication reliability may be determined as 'medium'. For example, in the embodiment of FIG. 8(b), the vehicle Bluetooth module 200 did not recognize the first-priority device (device A), but within the number (ie, “2”) of the number of authentication devices (“2”). Since the second-priority registration device (device B) was recognized among the registration devices of priority (ie, first or second priority), in this case, the authentication reliability can be determined as 'medium'.

(iii) If the vehicle Bluetooth module 200 recognizes registration devices greater than or equal to the number of authentication devices, but does not recognize registration devices having priority within the number of authentication devices, authentication reliability may be determined as 'low'. . For example, in the embodiment of FIG. 8(c), the vehicle Bluetooth module 200 recognizes the number of authentication devices ("2") or more registered devices (ie, C devices and D devices). However, only registered devices with priority 3 or lower were recognized, not registered devices with priority (i.e., 1st or 2nd priority) within the number of authentication devices ("2"), so in this case, the authentication reliability was set to 'low'. can be judged by

As described above, the method or criterion for dividing the level of authentication reliability may vary depending on the specific embodiment of the invention. In addition, the above-described calculation of the authentication reliability and the additional authentication step according thereto may be executed, for example, in the user authentication step (S650) of FIG. 7, but is not limited thereto.

Fig. 9 shows another exemplary embodiment of registering a Bluetooth device in a registered device list.

In the embodiment of FIG. 9 , the user may group and store the devices registered in the registered device list 10 into one or more registered device sets. Referring to FIG. 9, it is assumed that a plurality of users have registered a total of 8 Bluetooth devices (device A to H) in the registration device list 10. At this time, for example, the first user sets A, B, and C devices as the first registration device set S1, and the second user sets D, E, and C devices as the second registration device set S2. can be set to At this time, it will be appreciated that one device, such as device C, may be overlapped and registered in two or more registration device sets S1 and S2.

In this way, when a plurality of users share a vehicle, each user sets his or her own set of registration devices and can perform user authentication only for the registration devices within the set of registration devices set by each user. Even in the case of sharing a vehicle, convenient and simple authentication is possible while improving the authentication security of each driver.

A function of setting the number of authentication devices may be added to the embodiment of FIG. 9 . For example, when the first user sets the number of authentication devices to 2, authentication can be successful when the first user gets into a vehicle with any two devices of A, B, and C.

As another example, an authentication reliability function may be added to the embodiment of FIG. 9 . For example, in the embodiment of FIG. 9 , when the first user sets the number of authentication devices to 2 and priorities are set in the order of device A, device B, and device C, for example, the first user sets devices B and device C. When carrying and riding in a vehicle, the vehicle Bluetooth module 200 determines the authentication reliability as 'medium' and may request additional authentication.

As another example, when the vehicle Bluetooth module 200 detects two or more first-priority devices of each registration device set, (i) performs the above-described authentication procedure for the registration device set to which any detected first-priority device belongs. Alternatively, (ii) if a plurality of first-priority devices are detected, it may be determined that authentication has been successful for all of the plurality of users.

For example, in the embodiment of FIG. 9 , when a first user sets priorities in the order of A device, B device, and C device, and a second user sets priorities in the order of D device, E device, and C device. , If the first user possesses the first-priority device (device A) and the second user also carries the first-priority device (device D) and rides in the vehicle, according to the method (i) above, the first registration device For any one of the set S1 and the second registration device set S2, user authentication may be performed depending on whether or not the other registration devices in the set are recognized based on the number of authentication devices set in the set. For example, user authentication may be performed for the first registration device set S1, and user authentication may be performed by determining whether the first user has two or more registration devices.

In this case, according to the method (ii) above, the vehicle Bluetooth module 200 (for example, even if the number of authentication devices is set to '2' in advance) is the first user's first device and the second user's first priority device. Since the devices are simultaneously recognized, both the first and second users can be authenticated as authorized users. That is, when a plurality of users each having a first-priority device board the board, user authentication can be completed regardless of the presence or absence of a second-priority device in each user's registration device set.

An exemplary flowchart of the operation of the Bluetooth module 200 for a vehicle described above with reference to FIG. 9 will be described with reference to FIG.

10 is a flowchart of an exemplary user authentication method in the case where a plurality of registration device sets are set and the number and priority of authentication devices are set for each registration device set, and may be executed in step S640 of FIG. 7, for example.

Referring to FIG. 10, a vehicle Bluetooth module 200 receives a beacon signal broadcast from a plurality of Bluetooth devices carried by a user riding in a vehicle or pre-installed in the vehicle, and extracts identification information of the Bluetooth device from the beacon signal. Then, the vehicle Bluetooth module 200 compares the extracted identification information with the identification information of the registration device list 10 as shown in FIG. 9 in step S641.

As a result of the comparison, if there is one first-priority registration device in the extracted identification information (S643_Y), a user authentication procedure for the registration device set to which the first-priority registration device belongs is performed (S645). For example, based on the number of authentication devices set for the corresponding registration device set, user authentication may be performed by determining whether there is identification information extracted even for registration devices ranked second or lower (S650).

If two or more first-order registration devices exist in the identification information extracted as a result of the comparison (S647), one of the first registration device set and the second registration device set is selected according to the method (i) described with reference to FIG. For , user authentication may be performed according to whether or not the registration devices of the remaining ranks in the corresponding set are recognized based on the number of authentication devices set in this set (S649 and S645). Or, alternatively, according to the method (ii) described with reference to FIG. 9, both the first and second users are authenticated as authorized users because the first-priority device of the first user and the first-priority device of the second user are recognized at the same time. It may be done (S650).

And, although not shown in FIG. 10, for example, if the vehicle Bluetooth module 200 does not recognize the first-rank registration device of any registration device set, this is for the registration device set to which the highest-ranking registration device belongs in the extracted identification information. It will be understood that the user authentication procedure can be performed based on the number of authentication devices set in the registration device set.

Therefore, according to the user authentication method for a vehicle according to an embodiment of the present invention as described above, user authentication is possible conveniently and simply from the user's point of view even if the user does not necessarily possess a mobile phone (generally set as the first priority). In addition, according to an embodiment of the present invention (mobile phone, earphone, speaker, smart watch, etc.), at least one of Bluetooth devices that are frequently used by users or Bluetooth devices (preferably, turned on / off) fixedly installed in a vehicle Since driver authentication can be performed using identification information, there is a technical advantage of improving the security of driver authentication and enabling more convenient and convenient authentication from the user's point of view.

As described above, those skilled in the art to which the present invention pertains can understand that various modifications and variations are possible from the description of this specification. Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, but should be defined by not only the claims to be described later, but also those equivalent to these claims.
