[0002] With the recent development of IT technology, vehicles are provided with various services using IT technology, and such trend is rapidly spreading. In order to secure the service using the IT technology, access through the password input of the user is required.

Services that require a high level of security among the services the user wants to use in the vehicle, for example, a service for remotely manipulating the door lock of a house, financial services, and the like.

Since security is important in providing such a service, a user generally logs in to the corresponding service through an authentication process with a high degree of difficulty, such as inputting a password of a complex combination and authentication using a public certificate.

However, when the user logs in to the service through an authentication procedure having a high degree of difficulty during vehicle operation, it can be very inconvenient to a vehicle occupant who is a user. In particular, the driver is more likely to cause traffic accidents during the process of logging in to the service through a method having a high degree of difficulty while driving the vehicle.

Therefore, in this case, there is a need for a service login method through an authentication procedure that considers both the convenience of the user who boarded the vehicle and the high level of security.

Therefore, the embodiment relates to an authentication method and an authentication system using context information, taking into consideration convenience, safety and security of a user aboard a vehicle.

1 is a flowchart showing an authentication method of an embodiment. 2 is a diagram for explaining the authentication method of one embodiment. The authentication method of the embodiment may include an authentication information checking step S110, a list pop-up step S120, a context information checking step S130, a login method selecting step S140, and a login step S150.

In the authentication information verification step (S110), the control unit 100 can confirm the authentication information of the user inputted from the input means. The authentication method of the embodiment can be implemented, for example, on a vehicle.

Accordingly, the authentication information checking step S110 may include a step of checking the authentication information of the vehicle key registered in the controller 100, fingerprint information of the user, iris information, voice information, fingerprint information, Information and biometric signal information may be used as authentication information of the user. Further, the input means may be, for example, an authentication information module 110 described later.

Therefore, the control unit 100 can confirm whether the user is authorized to use the vehicle by receiving the authentication information from the user including the driver of the vehicle. If the control unit 100 has a right authorized to use the vehicle, the list pop-up step S120 may be performed.

In the list pop-up step S120, the display unit 200 provided in the vehicle may pop-up a list of services registered in the control unit 100. [

The list pop-up step S120 may pop up a list of, for example, Internet (IoT) services or telematics services.

The object Internet service includes, for example, an air conditioner provided in a user's home, an air conditioner such as a boiler, a home appliance, a computer provided in a user's office room, an office equipment, Lt; RTI ID = 0.0 > and / or < / RTI > other control means.

Telematics services can be various services that can be provided remotely, such as location information service, driving information service, financial service, amusement service, reservation service, commodity purchase service, etc. in the vehicle.

The telematics service may include not only a service actively selected by the user but also a recommendation service recommended by the telematics service provider to the user.

Accordingly, in the list popup step S120, a list related to the services may be popped up to provide the object internet or telematics service.

At this time, the services appearing in the service list are transmitted to the controller 100 provided in the vehicle from a server connected wirelessly with the controller 100, and are displayed on the display unit 200 connected to the controller 100. [ And displayed. This will be described in detail below.

In the context information checking step S130, the controller 100 compares the first context information registered in the controller 100 with the second context information derived from the current behavior pattern of the user, The degree of matching of the second context information with respect to the first context information can be confirmed.

The context information is information derived from the behavior pattern of the user. At this time, the behavior pattern of the user may be, for example, the user's vehicle use time, the destination setting information of the navigation provided in the vehicle, the fuel consumption driving mode that the user uses when the vehicle is traveling, have.

The first context information is previously derived from a behavior pattern of the user and is registered in the control unit 100.

The first context information may be information that the control unit 100 continuously acquires information on the behavior pattern of the user and stores and registers the information on the behavior pattern of the user. Accordingly, the first context information may be information on a certain behavior pattern of the user.

On the other hand, the second context information is information derived from the current behavior pattern in which the user uses the vehicle, that is, the approval information confirmation step, and is not currently registered in the control unit 100.

The context information checking step (S130) may calculate a weight for at least a part of the plurality of current behavior patterns of the user, for example, to check the matching degree of the second context information with respect to the first context information have.

The weight can be calculated by adding scores expressed in Arabic numerals, and can be calculated differently according to the behavior pattern of the user included in the context information. Hereinafter, a weight calculation method will be described as an example.

The weight can be calculated by comparing the difference between the current vehicle use time of the user, which is the second context information, and the vehicle usage time of the first context information, for example. The vehicle usage time may be, for example, the time at which the authentication information verification step S110 is performed.

In this case, the vehicle usage time on the first context information may be a value obtained by continuously collecting the user's vehicle usage time previously.

Specifically, the total weight of the vehicle usage time is determined, the vehicle usage time on the first context information is compared with the current vehicle use time of the user, and the final weight is calculated by subtracting the total score of the weight as the degree of discrepancy increases .

For example, if the total weighted point of the vehicle use time is 35 points and the current vehicle use time has an error of less than 10 minutes from the vehicle usage time on the first context information, it may not be deducted from the weighted total point, The weight can be 35 points.

If the current vehicle use time exceeds the car use time on the first context information by more than 10 minutes and less than 20 minutes, the final weight can be 30 points by subtracting 5 points from the total weighted point.

In this way, the final weight can be calculated by dividing the error by 10 minutes and subtracting 5 points each from the total weight. Of course, if the 35 points are subtracted, the final weight is 0, and the final weight may not be negative.

The weight may be calculated by comparing the difference between the current destination setting information of the navigation provided in the vehicle and the destination setting information on the first context information.

For example, it is possible to set the weighted total point with respect to the destination setting information of the navigation to 35 points, and set the distance from the destination on the first context information to, for example, 1 km.

At this time, if the distance between the current destination and the destination on the first context information is less than 1 km, the weighted total point may not be deducted, and thus the final weighted value may be 35 points.

If the distance between the current destination and the destination on the first context information is more than 1 km and less than 2 km, the final weight can be 30 points by subtracting 5 points from the total weight.

In this way, the final weight can be calculated by dividing the distance difference by 1km and deducting 5 points each from the total weight. Of course, if the 35 points are subtracted, the final weight is 0, and the final weight may not be negative.

The weight may be calculated by comparing the difference between the current fuel efficiency driving mode of the vehicle and the fuel consumption driving mode on the first context information.

Here, the fuel economy driving mode includes, for example, an eco mode, a normal mode, and a sports mode, wherein the eco mode has the highest fuel economy, the sports mode has the lowest fuel economy, And can have fuel economy intermediate between the eco mode and the sports mode.

For example, if the weighted total score for the fuel efficiency mode is set to 30 points and if the fuel efficiency mode matches the fuel efficiency driving mode on the first context information, the weighted total score may not be subtracted, and thus the final weight value may be 30 points.

In addition, if the inconsistency with the fuel consumption driving mode on the first context information, the final weight can be 15 points by subtracting 15 points from the weight total point.

Specifically, if the fuel consumption operation mode on the first context information is the normal mode and the current fuel consumption operation mode is the normal mode, the weighted total score may not be subtracted and the final weight may be 30 points.

 On the other hand, if the current fuel efficiency driving mode is the eco mode or the sports mode, the final weight can be 15 points by subtracting 15 points from the weight total score.

In the login method selection step S140, the controller 100 can select the login method for the service of the user based on the checked context information.

In the login method selection step (S140), the login difficulty for the service may be set differently according to the degree of matching of the second context information with respect to the first context information.

In the login method selection step (S140), as the degree of matching of the second context information with respect to the first context information is higher, the login difficulty for the service can be set lower.

The higher the degree of matching of the second context information with respect to the first context information is, the more likely it is that the person who intends to use the services registered in the controller 100 registers the services in the controller 100 in the beginning.

Thus, a low level of security is sufficient for accessing the service, and thus the login difficulty for the service can be set low.

For example, when providing services related to door locks, gas devices, and the like, which are provided in a user's home in the Internet service of objects, a very high level of access security is required due to the characteristics thereof. On the other hand, There is also a need to simplify access to Internet services.

In addition, even when providing services related to financial services among telematics services, a very high level of access security is required, while it is also necessary to simplify access to Internet services for users for convenience of users.

Therefore, in the embodiment, the security information is firstly authenticated in the authentication information confirmation step S110, and the security information is authenticated in the context information confirmation step S130. In the context information verification step S130, By varying the security level according to the degree of matching of the second context information, it is possible to maintain strict security when accessing the service and to provide convenience to the user.

The login method selection step S140 may include a first step in which the login difficulty is the lowest, a third step in which the login difficulty is the highest, and a third step in which the login difficulty is higher than the first step, And a lower second stage.

Referring to FIG. 2, in the context information checking step (S130), when the degree of matching of the second context information with respect to the first context information is the highest, the controller 100 can select the first step login method.

If the degree of matching of the second context information with respect to the first context information is intermediate in the context information checking step S130, the control unit 100 can select the second-step login method.

If the degree of matching of the second context information with respect to the first context information is the lowest in the context information checking step (S130), the controller 100 can select the third method of login.

The degree of matching of the information can be determined by calculating the weights as described above. That is, the degree of matching of the information can be determined by dividing the total weight expressed by the sum of the final weights calculated by comparing the difference in the vehicle use time, the difference in the destination setting information, and the difference in the fuel consumption driving mode .

If the total weight is 80 or more, the degree of matching of the second context information with respect to the first context information is classified as the highest, and the control unit 100 can select the first step login method.

If the total weight is more than 50 points and less than 80 points, the degree of matching of the second context information with respect to the first context information is classified as intermediate, and the controller 100 can select the second- have.

If the total weight is less than 50 points, the degree of matching of the second context information with respect to the first context information is classified as lowest, and the controller 100 can select the third method of login.

Meanwhile, as described above, since the final weight is not a negative value, the total weight may not be a negative value.

The first step may be provided, for example, to log into the service with one or two numeric inputs. That is, the first step is to log in to the service in the least difficult way.

The first-step login method can be selected when the degree of matching of the second context information with respect to the first context information is the highest. Therefore, in this case, even if you log in with a simple login method, there is no particular problem with security.

On the other hand, when the service is logged in by the first step, the control unit 100 may allow the user to access all of the plurality of services.

It is very likely that a person who intends to use the services registered in the control unit 100 in the first step is a party who originally registered the services in the control unit 100. Therefore, Is appropriate.

The second step may be provided to log into the service by inputting a password in combination of numbers and characters, for example. That is, the second step may log in to the service by a method having a degree of difficulty intermediate between the first step and the third step.

The login method of the second step can be selected when the degree of matching of the second context information with respect to the first context information is intermediate. In this case, it is appropriate to allow login in a way that has moderate difficulty considering both user's convenience and access security.

When the service is logged in by the second step, the control unit 100 may allow the user to access the selected one of the plurality of services.

Since the possibility that the person who intends to use the services registered in the control unit 100 in the second step is a party who originally registered the services in the control unit 100 is lower than that in the first step, It is appropriate to allow user access to the selected service.

At this time, selection of a service can be selected by the control unit 100 or by a person who has logged in. If necessary, the control unit 100 may restrict a user who is logged in from being unable to select a service that requires high security.

The third step may be provided to log into the service by, for example, an authorized certificate authentication or a cellular phone authentication. That is, the third step may log in to the service in the method having the highest degree of difficulty from the first step to the third step.

The login method of the third step can be selected when the degree of matching of the second context information with respect to the first context information is the lowest. In this case, it is very likely that the person who is trying to log in does not have access to the service, or the person who has access to the service logs in on behalf of the person who has access to the service.

Therefore, in this case, securing access security is very important, so it is appropriate to allow login with the highest degree of difficulty, which is more difficult than the second step.

When the service is logged in by the third step, the control unit 100 may allow the user to access the selected one of the plurality of services only once.

As described above, in this case, it is very likely that the logged-in user does not have access to the service or logs in instead of the person who has access to the service.

Therefore, in the third step, it is appropriate to limit the use of the user's service more than the case of the second step in consideration of access security for the service.

At this time, selection of a service can be selected by the control unit 100 or by a person who has logged in. If necessary, the control unit 100 may restrict a user who is logged in from being unable to select a service that requires high security.

Meanwhile, as shown in FIG. 2, the authentication method of the embodiment may be configured to proceed from the list popup step (S120) to the login method selection step (S140) through forced log-in.

This is because it is necessary to permit the use of the service even if the context information confirmation step can not proceed due to malfunction of the authentication system or for other reasons, or even when the user is not willing to proceed with the context information confirmation step.

In the case of the forced log-in, it may be provided to log in the service through the third step.

In the case of such a forced log-in, it is appropriate to log in to the service by the third-level method having the highest level of difficulty because the security information is not passed through the secondary security authentication in the context information confirmation step and a high level of security is required.

Of course, since the service is logged in to the service by the third step, in consideration of the access security for the service, the control unit 100 controls the service of the selected service among the plurality of services, To be accessible.

In the login step S150, the control unit 100 may allow the user to log in to the service registered in the control unit 100 according to the selected login method. As described above, the selected login method may be any one of the first to third steps, and the first to third steps may have different login difficulties.

Meanwhile, in the authentication method of the embodiment, the control unit 100 may be provided to set the number of times or the period for confirming the user's authentication information.

The user may desire to receive various services such as the object Internet service and the telematics service through the authentication method of the embodiment, or may not.

Accordingly, in consideration of the convenience of the user, the control unit 100 can set the number of times or the period of providing the authentication method of the embodiment. To this end, the control unit 100 can set the number of times or the period for checking the authentication information of the user have.
