Description

  The present invention relates to a mobile terminal that authenticates a service providing apparatus, an authentication system using the mobile terminal, and an authentication method for a service providing apparatus using the mobile terminal.

  In a conventional portable terminal, as a security function in the case of being stolen or the like, when making a transmission request or a location registration request to the communication network, a stop for stopping the operation of the portable terminal on a signal received from the communication network side It has a function of determining whether or not a request signal (remote lock signal) is included. When the stop request signal is included, the use of the subscriber data in the portable terminal is prohibited and the access function to the user data (personal information such as an email address) is stopped. Further, when the communication network side receives a call origination request or a location registration request from a mobile terminal, it refers to the subscriber information database and determines whether or not the mobile terminal is a registered regular one. It is determined whether or not a function stop (lock) instruction is set, and if it is illegal or a function stop instruction is set, a stop request signal is generated and transmitted to the mobile terminal To do. As a result, remote lock can be performed quickly and reliably on a stolen portable terminal (see, for example, Patent Documents 1 and 2).

  Moreover, in a portable terminal incorporating an IC (Integrated Circuit) card having an electronic money function, the portable terminal itself has a function of locking the IC card. The portable terminal periodically checks the battery usable time by software, and automatically sets the IC card lock when the battery usable time reaches a set threshold value. When the battery is charged, the lock is displayed, and the lock is released after authentication (input of a personal identification number, password, etc.) is performed (see, for example, Patent Document 3).

This user key is an arbitrary character string (including numbers and symbols), and the same character string (including numbers and symbols) as the user key registered in the registration information memory 11 of the mobile terminal 10 is provided in advance. It is assumed that the device 20 is also notified.

  The calling unit 13 includes a microphone, a speaker, and the like, and has a function for allowing a user to call the operator of the service providing apparatus 20 via the network 30. The communication unit 14 has a function for performing data communication with the service providing apparatus 20 via the network 30. The operation unit 15 includes a button or the like, and accepts an operation for the user to cause the mobile terminal 10 to perform a desired operation such as a call or communication. The display unit 16 includes a display device and the like, and displays a screen as necessary to the user.

  The service providing device 20 is on the service provider side, receives a call for a service use request from the mobile terminal 10, and after authentication, provides the requested service while remotely operating the mobile terminal 10 by an operator's operation. Device. A user information database (hereinafter referred to as DB) 21 records information for identifying a user. The user specifying means 22 searches the user information DB 21 using the caller telephone number as a search key, and specifies the mobile terminal 10 that has transmitted the service use request and the user. The data communication connection request means 23 sends a connection request for data communication to the mobile terminal 10 together with the user key of the user information to the mobile terminal 10 specified by the user specifying means 22.

FIG. 3 is a diagram illustrating an example of user information stored in the user information DB 21 of the service providing apparatus 20. In the user information DB 21, a name, a telephone number (call contact), etc. are registered as user information, and an e-mail address, a terminal ID number (terminal-specific identification) are stored as information on the mobile terminal 10 owned by the user. No., SIM: Subscriber Identity Module card-specific identification number, IP: Internet Protocol address, etc.), setting information when making a data communication connection request for remote operation (use of user key, user key information), etc. It is registered.
As the service providing apparatus 20, for example, a service providing apparatus 20 of a highly reliable service provider contracted by the user is assumed, and the service providing apparatus 20 receives a user key notification from the mobile terminal 10 in advance. It is registered in the user information DB 21 in advance.

  The command generation unit 24 generates a processing command describing an instruction for remotely operating the mobile terminal 10 with which the data communication connection has been established. The call means 25 includes a microphone, a speaker, and the like, and has a function for an operator to make a call with the user of the mobile terminal 10 via the network 30.

The display means 28 includes a display device and the like, and displays a screen as necessary to the operator.

  The processing command is, for example, a remote operation command for substituting the operation procedure of the portable terminal 10 when the user forgets the operation procedure. For example, the volume control of the speaker and the volume of the microphone are performed as the remote operation. Adjustment, camera activation, captured image transmission, text message transmission, contact memory registration, and the like are possible. Here, processing commands corresponding to each function of the mobile terminal 10 are registered in advance in the command generation means 24, and when the operator instructs the volume adjustment of the speaker of the mobile terminal 10 via the operation means 15, the command generation means 24 A processing command corresponding to the instruction content is selected and transmitted from the communication means 14 to the portable terminal 10.

The network 30 includes a communication line that connects the mobile terminal 10 and the service providing apparatus 20 to enable a call, and a communication line that enables data communication. When the mobile terminal 10 is configured by a mobile phone, for example, the network 30 includes a base station of a mobile phone carrier.
The data communication method between the mobile terminal 10 and the service providing apparatus 20 may be any method. For example, the mobile terminal 10 always issues a request to the service providing apparatus 20, and the service providing apparatus 20 The request may be included in the response to. Further, for example, the network 30 includes a relay server that relays a communication line such as a mobile phone network of a mobile phone carrier and a communication line such as the Internet, and the service providing apparatus 20 designates the telephone number of the mobile terminal 10 as the relay server. Then, the request may be issued, and the relay server may connect to the mobile terminal 10 having the designated telephone number to transmit the request, receive the response, and send it back to the service providing apparatus 20. Further, for example, when a unique address (such as an IP address) is allocated to the mobile terminal 10, the mobile terminal 10 notifies the service providing apparatus 20 of the IP address, and the service providing apparatus 20 requests the IP address. May be issued.

Next, the operation of the authentication system will be described.
FIG. 4 is a flowchart showing the operation of the mobile terminal 10. When the user operates the operation means 15 from the initial state to make a call for service use request to the service providing apparatus 20 registered in the registration information memory 11 (step ST1 “YES”), the call means 13 registers. According to the received telephone number, connection is made to the service providing apparatus 20 via the telephone line of the network 30 (step ST2). When there is no user call instruction (step ST1 “NO”), and when the line connection with the service providing apparatus 20 cannot be established and the call cannot be made (step ST2 “NO”), the process returns to the initial state.
Steps ST1 and ST2 constitute a call step.

If the call can be made by connecting to the service providing device 20 (step ST2 “YES”), the call means 13 performs a voice call between the user and the operator of the service providing device 20 (step ST3). Tell the operator that you want to use the desired service. When the communication means 14 receives a data communication connection request from the service providing apparatus 20 during a voice call (step ST4 “YES”), the user key assigned to the data communication connection request received by the authentication means 12 is registered. It collates with the user key registered in the information memory 11 (step ST5). If the character information of the user key received from the service providing apparatus 20 is correct as a result of the collation (step ST6 “YES”), the authentication unit 12 provides a response to start data communication via the communication unit 14 It transmits to the apparatus 20 (step ST7).
Step ST4 constitutes a key reception step, steps ST5 and ST6 constitute an authentication step, and step ST7 constitutes a response transmission step.

On the other hand, when there is no data communication connection request from the service providing device 20 (step ST4 “NO”), and when the user key is not correct (step ST6 “NO”), the process is terminated together with the end of the call.
If the user key has not been authenticated in step ST6 (or if the user has not obtained consent), the authentication unit 12 does not transmit any response to the service providing apparatus 20 as described above. Alternatively, a response indicating that the connection is rejected may be transmitted.
In addition, when the user key is authenticated in step ST6, the authentication unit 12 causes the display unit 16 to display a screen for requesting the connection with the service providing apparatus 20, and the user by operating the operation unit 15 After accepting the approval, the process may proceed to step ST7. In this case, the security performance can be further enhanced.

Subsequently, the communication unit 14 receives the processing command transmitted from the service providing apparatus 20 via the communication line of the network 30 (step ST8). In step ST8, the remote control by the service providing apparatus 20 such as adjusting the volume of the speaker is performed by executing the processing command received by the mobile terminal 10. The mobile terminal 10 repeats the processing until the communication means 14 finishes executing all the processing commands received from the service providing apparatus 20 (step ST9 “NO”, ST8). The process ends with the end.
Steps ST8 and ST9 constitute a command communication step.

FIG. 5 is a flowchart showing the operation of the service providing apparatus 20. In the initial state, when the call means 25 receives a service use request call from the program information 10 via the communication line of the network 30 (step ST11 “YES”), the operator operates the call means 25 to start the call. At the same time, the user specifying means 22 searches the user information DB 21 using the caller telephone number as a search key, and specifies the caller mobile terminal 10 and its user (step ST12).
Steps ST11 and ST12 constitute a user specifying step.

The data communication connection requesting means 23 receives the user information specified from the user specifying means 22 and checks whether or not it is set to “use” the user key (step ST13). If it is set to use the user key (“YES” in step ST13), the data communication connection requesting means 23 gives the user key to the data communication connection request, and the communication means 26 is the communication line of the network 30. To the mobile terminal 10 (step ST14). When data communication is permitted as a result of authentication by the portable terminal 10, that is, when there is a connection permission response ("YES" in step ST15), the operator operates the operation means 27 so that the user A processing command for providing a service requested by a call is input to the service providing apparatus 20, and the command generating unit 24 selects a processing command corresponding to the input and transmits the selected processing command to the mobile terminal 10 via the communication unit 26 ( Step ST16).
Steps ST13 and ST14 constitute a connection request step, step ST15 constitutes a connection permission reception step, and step ST16 constitutes a command generation step.

  On the other hand, when there is no service use request call from the mobile terminal 10 (step ST11 “NO”), when the user key is set to “do not use” in the user information (step ST13 “NO”), and As a result of the authentication performed by the mobile terminal 10, when data communication is not permitted, that is, when there is no connection permission response within a predetermined time or there is a connection rejection response (step ST15 “NO”). Return to the initial state.

As described above, according to the first embodiment, the mobile terminal 10 receives the registration information memory 11 in which the telephone number of the service providing device 20 and the user key notified in advance are registered, and the registration information received by the user's call operation. Calling means 13 for making a call to the service providing apparatus 20 registered in the memory 11, and a data communication connection request to which a user key is given in advance when the calling means 13 is connected to the service providing apparatus 20 via a call. Communication means 14 received from providing apparatus 20 and authentication means 12 for authenticating service providing apparatus 20 by collating the user key received by communication means 14 with the user key registered in registration information memory 11. The communication unit 14 transmits a response permitting connection to the service providing apparatus 20 authenticated by the authentication unit 12 to start communication, and the service providing apparatus 2 And configured to receive the processing command for remote operation from. In addition, the service providing apparatus 20 includes a user information DB 21 in which the telephone number of the registration information memory 11 and a user key notified in advance are registered, a call unit 25 that receives a call from the mobile terminal 10, and a call unit. When the telephone 25 is connected to the mobile terminal 10, the user identification means 22 that obtains the user key notified in advance from the user information DB 21 using the caller telephone number as a search key, and the user identification means 22 A data communication connection requesting means 23 for giving the acquired user key to a data communication connection request for the portable terminal 10 and transmitting it from the communication means 26, and a command generating means 24 for generating a processing command for remotely operating the portable terminal 10. The communication means 26 is generated by the command generation means 24 when a connection permission response to the data communication connection request is received from the portable terminal 10. To constitute a processing command to transmit to the mobile terminal 10.
For this reason, since the service providing apparatus 20 transmits the user key notified in advance from the mobile terminal 10 to authenticate with the mobile terminal 10, the user of the mobile terminal 10 needs to input an authentication password or the like. And convenience can be improved. Further, unless the user operates the mobile terminal 10 to make a call, the service providing apparatus 20 is not authenticated, so that the security performance can be improved. Further, since the remote operation by the service providing device 20 is executed while the user is in a call with the operator, the user can feel secure because he can hear the explanation from the operator about what is being done.

  In the above description, the service providing device 20 is used to provide a service that acts as a proxy for the setting operation of the mobile terminal 10 after the operator hears a request from the user. However, the present invention is not limited to this. For example, when the mobile terminal 10 is a mobile phone, the service providing apparatus 20 can also be used for support operations that explain complicated mobile phone operations through remote operation and conversation.

Further, for example, the mobile terminal 10 may be used as an emergency call mobile terminal, and the service providing apparatus 20 may be used as an emergency call receiving apparatus that receives an emergency call. When the mobile terminal 10 is used for an emergency call, the user is not accustomed to the operation of the mobile terminal 10, or an emergency situation occurs in the user and some trouble occurs and the normal operation cannot be performed. Sometimes it becomes. In such a case, conventionally, an operator who has received an emergency call prompts the user to operate the mobile terminal 10 by voice and instructs the mobile terminal 10 to perform an appropriate operation. However, in the situation as described above, the user may not be able to operate the mobile terminal 10 accurately, and it may take time to deal with it.
On the other hand, the mobile terminal 10 according to the first embodiment is configured to accept the remote operation by authenticating the service providing apparatus 20 without the user performing an authentication operation such as password input. Even if it does not operate, the portable terminal 10 can operate | move appropriately.

In the first embodiment, the communication means 14 also disconnects the communication line when the call means 13 of the mobile terminal 10 disconnects the call line and terminates the call. The user key authentication from 20 is configured not to be accepted and the security performance is further improved. However, the present invention is not limited to this.
For example, when data communication for authentication cannot be performed during a call, authentication may be permitted for a certain time after the call ends. Specifically, the authentication unit 12 of the mobile terminal 10 authenticates the user key received from the service providing device 20 by comparing it with the user key of the registration information memory 11 within a certain time after the call ends. Alternatively, the authentication unit 12 verifies the user key received from the service providing apparatus 20 for authentication until the user disconnects the communication line and ends the data communication even after the call ends. To do.

  As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the configuration of the above-described embodiment, and does not depart from the gist of the present invention. Needless to say, any change in the design is included in the present invention.
