## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a telematics terminal in a vehicle and, more particularly, to an apparatus and method for authenticating a telematics terminal in a vehicle.
2. Description of the Related Art
In general, a telematics terminal is mounted in a vehicle and provides a call function, map information, traffic information, multimedia information and GPS navigation function, etc., to users through a wireless communication network.
FIG. 1 is a block diagram showing a telematics system according to a related art.
As shown in FIG. 1, the related art telematics system includes an information providing center 30 for providing telematics service information such as the call function, the map information, the traffic information and the multimedia information; and a telematics terminal 10 mounted within a vehicle, receiving the telematics service information through a wireless communication network 20, and provides the telematics service information to a user. Herein, by inputting authentication information to the telematics terminal, the user can use the telematics service information through the telematics terminal 10.
However, with the related art telematics terminal 10, the user should input the user authentication information whenever he/she uses the telematics service, causing user inconvenience.
In addition, when currently inputted authentication information is not identical to pre-set user authentication information, the related art telematics terminal 19 just cuts off (prevents) the telematics service information. For example, when the currently inputted authentication information is not identical to the pre-set user authentication information, the related art telematics terminal simply prevents the telematics service information, causing a problem that it cannot discriminate whether the authentication information has been inputted by an actual user (e.g., an owner of a vehicle) or inputted by someone else. Thus, although the vehicle of the owner has been stolen by a person and erroneous authentication information has been inputted by the person, the owner of the vehicle cannot promptly know about the fact that his/her vehicle has been stolen.
SUMMARY OF THE INVENTION
One exemplary feature of the present invention is to provide an apparatus and method for authenticating a telematics terminal capable of receiving a first telematics service based on inputted user authentication information and then easily receiving a second telematics service based on the inputted user authentication information.
Another exemplary feature of the present invention is to provide an apparatus and method for authenticating a telematics terminal capable of allowing an owner of a vehicle to quickly determine whether or not his/her vehicle has been stolen by promptly providing an authentication failure message informing that user authentication of a telematics terminal mounted within a vehicle has been failed as occurs.
To implement at least the above feature in whole or in parts, the present invention provides a method for authenticating a telematics terminal in a vehicle including: storing user authentication information inputted to receive a first telematics service through a mobile communication network; and requesting a second telematics service to an information providing center through the mobile communication network based on the stored user authentication information.
To implement at least the above feature in whole or in parts, the present invention also provides a telematics terminal in a vehicle including: a storage unit for storing user authentication information to receive a first telematics service through a mobile communication terminal; and a controller for requesting a second telematics service from an information providing center based on the stored user authentication information through the mobile communication network.

DETAILED DESCRIPTION OF THE INVENTION
An apparatus and method for authenticating a telematics terminal capable of receiving a first telematics service based on inputted user authentication information and then easily receiving a second telematics service based on the inputted user authentication information according to exemplary embodiments of the present invention will be described with reference to FIGS. 2 and 3.
FIG. 2 is a schematic block diagram showing an apparatus for authenticating a telematics terminal according to a first embodiment of the present invention.
As shown in FIG. 2, the apparatus for authenticating a telematics terminal according to a first embodiment of the present invention includes: an input unit 21 for inputting user authentication information according to a first telematics service request; a storage unit 23 for storing the user authentication information; a transceiver 24 for transmitting the user authentication information to an information providing center 30 through a mobile communication network 20 or receiving user authentication request information; and a controller 25 for displaying user authentication information stored in the storage unit 23 on a screen of a display unit 22 when a second telematics service is requested by a user, and outputting selected user authentication information to the transceiver 24 when the user authentication information displayed on the screen of the display unit 22 is selected by the user. In this case, the transceiver 24 transmits the selected user authentication information to the information providing center 30 through the wireless communication network 20.
The operation of the apparatus for authenticating the telematics terminal according to the first exemplary embodiment of the present invention will now be described in detail with reference to FIG. 2.
First, when the first telematics service is requested by the user, the input unit 21 outputs a request signal for requesting the first telematics service to the controller 25.
The controller 25 transmits the request signal to the information providing center 30 through the transceiver 24. In this case, the information providing center 30 checks whether the first telematics service requires user authentication, and if the first telematics service requires user authentication, the information providing center 30 outputs a request signal for requesting user authentication information to the controller 25 through the transceiver 30.
The controller 25 receives the request signal for requesting the user authentication information, and if the user authentication information has not been stored in the storage unit 23 (e.g., when the telematics terminal is turned on to first use a telematics service), the controller 25 generates a message for requesting the user authentication information and outputs the message on the display unit 22. In this case, the display unit 22 displays the message on its screen.
When the user authentication information is inputted by the user, the input unit 21 outputs the inputted user authentication information to the controller 25.
The controller 25 outputs the user authentication information to the storage unit 23 and the transceiver 24. In this case, the storage unit 23 stores the user authentication information and the transceiver 24 transmits the user authentication information to the information providing center 30 through the wireless communication network.
Thereafter, when the second telematics service is requested by the user, the input unit 21 outputs a request signal for requesting the second telematics service to the controller 25.
The controller 25 transmits the request signal to the information providing center 30 through the transceiver 24. In this cast, the information providing center 30 checks whether the second telematics service requires user authentication. If the second telematics service requests user authentication, the information providing center 30 outputs a request signal for requesting the user authentication information to the controller 25 through the transceiver 30.
When the request signal for requesting the user authentication information is received, the controller 25 checks whether the user authentication information has been stored in the storage unit 23. When the user authentication information exists in the storage unit 23, the controller reads the user authentication information for the storage unit 23 and displays the read user authentication information on the screen of the display unit 22.
Thereafter, when the user authentication information displayed on the screen of the display unit 22 is selected by the user, the controller 25 transmits the selected user authentication information to the information providing center 30 through the transceiver 24.
If, however, the transmitted user authentication information is not valid for the second telematics service (e.g., when the second telematics service is a special service that incurs a high cost, not a basic service), the information providing center 30 requests the user authentication from the controller 25 of the telematics terminal and the controller 25 displays the request information for requesting the user authentication information for receiving the second telematics service on the screen of the display unit 22. In this case, the user can input new user authentication information to the input unit 21.
The method for authentication the telematics terminal according to the first exemplary embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3.
FIG. 3 is a flow chart illustrating the processes of a method for authenticating the telematics terminal according to the first embodiment of the present invention.
First, when the first telematics service is requested by the user, the input unit 21 outputs the request signal (or request information) for requesting the first telematics service to the controller 25 (step S11).
The controller 25 transmits the request signal to the information providing center 30 through the transceiver 24. The information providing center 30 checks whether the first telematics service requires user authentication. When the first telematics service requires the user authentication, the information providing center 30 outputs the request signal for requesting the user authentication information to the controller 25 through the transceiver 30 (step S12).
The controller 25 receives the request signal for requesting the user authentication information, and when the user authentication information has not been stored in the storage unit 23 (e.g., when the telematics terminal is turned on and first uses the telematics service), the controller 25 generates a message for inputting the user authentication information and outputs the message to the display unit 22. Then, the display unit 22 displays the message on the screen.
When the user authentication information is inputted by the user, the input unit 21 outputs the user authentication information to the controller 25.
The controller 25 outputs the user authentication information to the storage unit 23 and the transceiver 24 (step S13). At this time, the storage unit 23 stores the user authentication information (step S13A, and the transceiver 24 transmits the user authentication information to the information providing center 30 through the wireless communication network (step S13B). Herein, the information providing center 30 checks the validity of the user authentication information, and if the user authentication information is identical to pre-set user authentication information, the information providing center 30 provides the first telematics service (step S14).
Thereafter, when the second telematics service is requested by the user, the input unit 21 outputs the request signal for requesting the second telematics service to the controller 25 (step S25).
The controller 25 transmits the request signal to the information providing center 30 through the transceiver 24. Then, the information providing center 30 checks whether the second telematics service requires user authentication. If the second telematics service requests user authentication, the information providing center 30 outputs the request signal for requesting the user authentication information to the controller 25 through the transceiver 30 (step S16).
When the controller 25 receives the request signal for requesting user authentication information, it checks whether the storage unit 23 stores the user authentication information. The controller 25 searches the user authentication information from the storage unit 23, and when the user authentication information exists in the storage unit 23, the controller 25 reads the user authentication information from the storage unit 23 and displays the read user authentication information on the screen of the display unit 22 (step S17A). If, however, the user authentication information does not exist in the storage unit 23, the controller 25 requests the user to input user authentication information and transmits user authentication information inputted by the user to the information providing center 30.
Thereafter, when the user authentication information displayed on the screen of the display unit 22 is selected by the user, the controller 25 transmits the selected user authentication information to the information providing center 30 through the transceiver 24 (step S17). In this case, when the user authentication information is identical to the pre-set user authentication information, the information providing center 30 provides the second telematics service to the telematics terminal (step S18).
Herein, in terms of security, the controller may maintain the user authentication information only during a predetermined time period or while the telematics terminal is being turned on, and may delete the stored user authentication information when the telematics terminal is turned off.
In this manner, according to the authenticating apparatus and method according to the first embodiment of the present invention, after the first telematics service is received based on the inputted user authentication information, the second telematics service can be easily received based on the inputted user authentication information. For example, when the telematics service that requires user authentication is accessed, the telematics terminal transmits the user authentication information to the information providing center and at the same time stores the user authentication information, and then receives the new telematics service based on the stored user authentication information. Thus, the user authentication procedure can be simplified.
In addition, if the transmitted user authentication information is not valid for the telematics service (e.g., when the telematics service is not a basic service but a special service that incurs a high cost), the information providing center can request the user authentication from the telematics terminal again and the controller 23 can display the user authentication re-requesting message through the display unit 22. Accordingly, when the telematics terminal is in an OFF state, a non-authorized user can be prevented from receiving the telematics service that incurs a high cost.
An apparatus and method for authenticating the telematics terminal capable of allowing an owner of a vehicle to promptly recognize whether or not his/her vehicle has been stolen by quickly providing the owner an authentication failure message informing that user authentication of a telematics terminal mounted in the vehicle has been failed as occurs according to exemplary embodiments of the present invention will now be described in detail with reference to FIGS. 4 to 7.
FIG. 4 is a schematic block diagram showing an apparatus for authenticating a telematics terminal according to a second embodiment of the present invention;
As shown in FIG. 4, an apparatus 40 for authenticating a telematics terminal according to the second embodiment of the present invention includes: a controller 41 for requesting authentication information of the telematics terminal mounted in a vehicle when the telematics terminal is turned on, and generating an authentication failure message informing that authentication of the telematics terminal has been failed as authentication information inputted by a user in response to the request is not identical to pre-set authentication information; and a message transmission unit 42 for transmitting the authentication failure message to a reception unit 43 through wireless communication.
The reception unit 43 is a short distance wireless communication device previously determined by the owner of the vehicle corresponding to the pre-set authentication information and can be a communication device having a Bluetooth function. In this case, the message transmission unit 42 transmits the authentication failure message to the reception unit 43 of the owner of the vehicle through the short distance communication device such as the Bluetooth.
The operation of the apparatus for authenticating the telematics terminal according to the second embodiment of the present invention will now be described in detail with reference to FIGS. 4 and 5.
FIG. 5 is a flow chart illustrating the processes of a method for authenticating the telematics terminal according to the second embodiment of the present invention.
First, when the telematics terminal 20 mounted in the vehicle is turned on, the controller 41 requests user authentication information (step S51).
When a user inputs the authentication information in response to the request, the controller 41 compares the inputted authentication information and the pre-set authentication information (step S52).
When the inputted authentication information is identical to the pre-set authentication information (step S53), the controller 41 provides a service requested by the user (step S54). For example, when the inputted authentication information and the pre-set authentication information are identical, the controller 41 receives telematics service information such as a call function, map information, traffic information and multimedia information, etc. from the information providing center 30 through the wireless communication network 20, and provides the received telematics service information to the user (step S54). Herein, the technique for providing the telematics service information to the telematics terminal through the wireless communication network 20 is the same as that in the related art, so its detailed description will be omitted.
If, however, the inputted authentication information is not identical to the pre-set authentication information, the controller 41 generates an authentication failure message informing that authentication of the telematics terminal has been failed, and outputs the generated authentication failure message to the message transmission unit 42 (step S55).
The message transmission unit 42 transmits the authentication failure message received from the controller 41 to the reception unit 43 of the owner of the vehicle through the wireless communication device (e.g., the Bluetooth device) (step S56). Then, the owner of the vehicle can easily determine whether the cause of the authentication of the telematics terminal has been generated by him/her or whether it has been generated by someone else through the authentication failure message displayed on the reception unit 43, thereby quickly recognizing whether or not his/her vehicle has been stolen.
Also, the message transmission unit 42 can transmit the authentication failure message to a mobile terminal such as a mobile phone through the wireless communication network 20.
An apparatus for authenticating a telematics terminal according to a third embodiment of the present invention will be described with reference to FIG. 6.
FIG. 6 is a schematic block diagram showing an apparatus for authenticating a telematics terminal according to a third embodiment of the present invention.
As shown in FIG. 6, an apparatus 60 for authenticating a telematics terminal according to the third embodiment of the present invention includes: a controller 61 for requesting authentication information of the telematics terminal mounted in a vehicle when the telematics terminal is turned on, and generating an authentication failure message informing that authentication of the telematics terminal has been failed as authentication information inputted by a user in response to the request is not identical to pre-set authentication information; and a message transmission unit 62 for transmitting the authentication failure message to an information providing center 30 through the wireless communication network 20.
Herein, the information providing center 30 transmits the authentication failure message to a mobile terminal 63 previously determined by the owner of the vehicle corresponding to the pre-set authentication information through the wireless communication network 20. Accordingly, the owner of the vehicle can check the authentication failure message in a short distance area or from a remote area and easily determine whether or not his/her vehicle has been stolen based on the authentication failure message.
The operation of the apparatus for authenticating the telematics terminal according to the third embodiment of the present invention will now be described in detail with reference to FIGS. 6 and 7.
FIG. 7 is a flow chart illustrating the processes of a method for authenticating the telematics terminal according to the third embodiment of the present invention;
First, when the telematics terminal mounted in the vehicle is turned on, the controller 61 requests user authentication information (step S71).
When a user inputs the authentication information in response to the request, the controller 61 compares the inputted authentication information and the pre-set authentication information (step S72).
When the inputted authentication information is identical to the pre-set authentication information (step S73), the controller 61 provides a service requested by the user (step S74).
If, however, the inputted authentication information is not identical to the pre-set authentication information, the controller 61 generates an authentication failure message informing that authentication of the telematics terminal has been failed, and outputs the generated authentication failure message to the message transmission unit 42 (step S75).
The message transmission unit 62 transmits the authentication failure message received from the controller 61 to the information providing center 30 through the wireless communication network 20 (step S76).
Thereafter, the information providing center 30 transmits the authentication failure message corresponding to the pre-set authentication information to the mobile terminal 63 previously determined by the owner of the vehicle (step S77). Accordingly, the owner of the vehicle can easily determine whether or not the cause of the authentication failure of the telematics terminal has been generated by him/her or whether it has been generated by someone else through the authentication failure message displayed on the mobile terminal 63. That is, the owner of the vehicle can quickly determine whether or not his/her vehicle has been stolen from a short distance area or remote area.
The message transmission unit 62 can directly transmit the authentication failure message directly to the mobile terminal 63 through the wireless communication network 20, without going by way of the information providing center 30.
As so far described, according to the authenticating apparatus and method according to the first embodiment of the present invention, after the first telematics service is received based on the inputted user authentication information, the second telematics service can be easily received based on the inputted user authentication information. For example, when the telematics service that requires user authentication is accessed, the telematics terminal transmits the user authentication information to the information providing center and at the same time stores the user authentication information, and then the new telematics service can be received based on the stored user authentication information. Thus, the user authentication procedure can be simplified.
According to the apparatus and method for authenticating the telematics terminal according to the second and third embodiments, when the user authentication of the telematics terminal is failed, the authentication failure message is quickly provided to the owner of the vehicle to allow the owner of the vehicle to be quickly determined whether or not his/her vehicle has been stolen. For example, when the owner of the vehicle stays at home, if the authentication failure message is received by the reception unit or the mobile terminal, the owner of the vehicle can promptly recognize whether or not his/her vehicle has been stolen.
The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. In the claims, means-plus-function clauses are intended to cover the structure described herein as performing the recited function and not only structural equivalents but also equivalent structures.
