Description

The present invention relates to a migration method for changing a terminal used when receiving a service from a service providing system, a migration program, a service providing server for executing migration, and a service providing system.

In recent years, with the diversification of applications of mobile terminals such as smartphones (hereinafter referred to as "user terminals"), various services have been provided from servers to user terminals using networks.

When a user receives a service via a network, a procedure for authenticating whether or not the user terminal can access the service providing server is required (for example, Patent Documents 1 and 2).

At this time, by registering the information about the user terminal used when receiving the service provision in the service providing server in advance, the authentication at the time of access can be facilitated. However, the user may change the user terminal used to receive the service. For example, it is common practice to change to a new user terminal as the user terminal becomes old. In such a case, the user will be provided with the service on the new user terminal due to the change of the terminal to be used.

Therefore, the user needs to update the user terminal having the access right registered in the service providing server from the old terminal to the new terminal, but the procedure for obtaining the access right on the new terminal is generally complicated. be. Specifically, it is necessary to enter an ID and a password, or to re-enter the information entered in the past. In this case, if the ID or password is forgotten, the user cannot access his / her own data. Even if it can be accessed, multiple procedures are required for that purpose.

Hereinafter, the migration method, the migration program, the service providing server, and the service providing system according to the embodiment will be described with reference to the drawings. The migration method according to the embodiment is a migration method when the terminal registered in the service providing server is changed. The migration program is a program executed on the service providing server.

As shown in FIG. 1, in the service providing system 1, the service providing server 10 and the user terminal 20 (20, 20A, 20B) are connected to each other via the network 30. The service providing server 10 provides a service to the user terminal 20 held by the user via the network 30.

In FIG. 1, the user terminal 20A is a terminal used by a user to receive a service in the past (hereinafter, referred to as an "old terminal" as necessary). Further, the user terminal 20B is a terminal used by the user to newly receive the service (hereinafter, referred to as a "new terminal" as necessary). Here, since the new terminal 20B is connected to the network 30, the old terminal 20A is in a state where the connection with the network 30 is disconnected.

In this service providing system 1, when the terminal used by the user is changed from the old terminal 20A to the new terminal 20B, the migration process described later is executed using FIG.

In the following description, the user terminal 20 (20, 20A, 20B) is an information processing terminal such as a smartphone capable of data communication using an internet line (network) 30 and a call using a public network 40. And. The user terminal 20 is connected to the network 30 and the public network 40 managed by this business operator by contracting with a terminal provider different from the service providing server 10. Further, the service provided by the service providing server 10 is assumed to be the transmission / reception of messages between the user terminals 20 registered in the service providing server 10.

<Service provision server>
As shown in FIG. 1, the service providing server 10 is provided from a providing means 11a for providing a service to a registered user terminal 20, an acquisition means 11b for acquiring data for migration from the user terminal 20, and a user terminal 20. Decoding means 11c that decrypts the encrypted data included in the acquired data, determination means 11d that determines the establishment or failure of migration using the decoded data, and notification means 11e that notifies the user terminal of the determination result. The update means 11f for updating the data related to the user registered when the migration is established is provided.

The service providing server 10 includes information processing including a central processing unit (CPU) 11, a storage device 12 capable of storing data, and a communication interface (communication I / F) 13 used for transmitting and receiving data using an Internet line 30. It is a device. The storage device 12 stores user data 12a and a service providing program P1 regarding a user who provides a service. When the service providing program P1 is executed, the CPU 11 executes processing as the providing means 11a, the acquiring means 11b, the decoding means 11c, the determining means 11d, the notification means 11e, and the updating means 11f. More specifically, the migration program included in the service providing program P1 executes the migration process by the means 11b to 11f.

As shown in an example of FIG. 3, the user data 12a includes the "telephone number" and "terminal identifier (UDID)" of the user terminal 20 registered as the target of service provision, and the "token" given in advance by the service providing server 10. It is data including a record to which a "code" or the like is associated. For example, the service providing server 10 assigns a token code to the user terminal 20 at the time of user registration. Further, in the example of the user data 12a shown in FIG. 3, each record is specified by the identification number “No.”.

The providing means 11a executes a service providing process in response to a service providing request from the registered user terminal 20. Further, the providing means 11a executes the user registration process in response to the registration request from the unregistered user terminal 20. For example, the registration request includes the terminal identifier D1 of the user terminal 20, the telephone number D2, and the user information D3. At the time of user registration, a record relating to a new user is added to the user data 12a described above using FIG. 3 by using each information included in the registration request. Further, at the time of user registration, the providing means 11a transmits the unique token code D4 and the public key D5 to the user terminal 20. Here, detailed description of the service provision process and the user registration process will be omitted.

The acquisition means 11b acquires the terminal identifier D11, the encrypted data D8, and the passcode D10 transmitted from the new terminal 20B as a migration request via the communication I / F13. Here, the terminal identifier D11 is the terminal identifier D11 of the new terminal 20B, and the passcode D10 is a passcode (hereinafter referred to as "second passcode D10") input by the user at the new terminal 20B. Further, the encrypted data D8 is data acquired by the new terminal 20B from the old terminal 20A.

The decryption means 11c decrypts the encrypted data D8 acquired by the acquisition means 11b. The encrypted data D8 includes a token code D4, a passcode D4, and a terminal identifier D1. Here, the passcode D4 is a passcode (hereinafter referred to as "first passcode D4") input by the user on the old terminal 20A. Further, the terminal identifier D1 is the terminal identifier D1 of the old terminal 20A. The encrypted data D8 is encrypted by the public key D5 previously provided to the old terminal 20A by the service providing server 10. Further, the decryption means 11c decodes with the private key D12 corresponding to the public key.

The determination means 11d determines whether or not the first pass code D4 included in the encrypted data D8 decrypted by the decryption means 11c and the second pass code D10 acquired by the acquisition means 11b match. Further, if the determination means 11d matches, the determination means 11d determines that the migration has been established, and if they do not match, the determination means 11d determines that the migration has not been established.

That is, when the first pass code D4 input by the old terminal 20A and the second pass code D10 input by the new terminal 20B match, the determination means 11d inputs the pass codes D4 and D10 by the same person. It is judged that the migration is successful. On the other hand, when the first pass code D4 input by the old terminal 20A and the second pass code D10 input by the new terminal 20B do not match, the determination means 11d inputs the pass codes D4 and D10 by another person. Since it is highly possible that the migration was not successful, it is determined that the migration has not been established.

The notification means 11e transmits the determination result of the determination means 11d to the user terminal 20 as a response to the migration request via the communication I / F13.

When the determination means 11d determines that the migration is successful, the update means 11f uses the terminal identifier associated with the token code included in the migration request as the terminal identifier of the new terminal included in the migration request in the user data 12a. Rewrite and update the user data 12a. That is, the updating means 11f rewrites the terminal identifier of the old terminal 20A of the user data 12a to the terminal identifier of the new terminal 20B. This completes the migration procedure. As a result, the user can perform migration without inputting the user ID and password at the time of service registration.

<User terminal>
The user terminal 20A is a terminal (old terminal) that the user has used so far when receiving a service from the service providing server 10. Further, the user terminal 20B is a terminal (new terminal) that the user will use when receiving a service from the service providing server 10 in place of the old terminal 20A. The configurations of the user terminals 20A and 20B are basically the same, but in FIG. 1, only the configurations necessary for the user terminals 20A as the old terminals at the time of the migration procedure are shown. Further, in FIG. 1, as the user terminal 20B, only the configuration required as a new terminal during the migration procedure is shown.

The user terminal 20 is a terminal including a CPU 21, a storage device 22, a communication means 23, an operation input means 24, a display 25, a microphone 26, a speaker 27, and a camera 28. The user terminal 20 can receive the service from the service providing server 10 by registering the user in the service providing server 10 and storing the service program P2 in the storage device 22 and executing the service program P2. can.

The communication I / F 23 is a means used for transmitting / receiving data via the Internet line 30 and making a call via the public network 40. The means used for transmitting and receiving data via the Internet line 30 and the means used for calling via the public network 40 may be different, but here, the description is simplified. Therefore, it is described as being the same.

The operation input means 24 is a means used by the user to input an operation signal, such as an operation button or a touch panel. The operation input means 24 can input an operation signal of a data communication using the Internet line 30 or a call using the public network 40, in addition to the case where the service is provided from the service providing server 10.

The display 25 is a means for outputting text data and image data necessary for a user terminal 20 such as a liquid crystal display. The microphone 26 is used for making a call using the public network 40 and inputting other voice data. The speaker 27 is used for making a call using the public network 40 and outputting other voice data. The camera 28 is used for acquiring image data.

《Old terminal》
The CPU 21 of the user terminal 20A, which is the old terminal, executes the service program P2 stored in the storage device 22 for the migration procedure, so that the storage processing means 21a, the display processing means 21b, the encryption means 21c, and the QR code are executed. The process as the changing means 21d is executed.

As a preparation for the migration procedure, the storage processing means 21a previously stores the unique token code D4 and the public key D5 transmitted from the service providing server 10 to the user terminal 20A via the communication I / F 23 to the storage device 22. Remember in.

Further, the storage processing means 21a deletes the data used in the service providing system 1 after the migration is completed. The data deleted by the storage processing means 21a includes the token code D4, the public key D5, and other data acquired in the past via the service providing system 1. Since the old terminal 20A cannot specify the timing of completion of migration, specifically, the storage processing means 21a displays data at the timing when a predetermined time elapses after the display processing means 21b displays the QR code. To delete. Alternatively, the storage processing means 21a is the timing at which the operation signal for which migration is completed is input by the user.

The display processing means 21b is a request signal requesting a migration procedure via the operation input means 24 after the communication by the Internet line 30 and the communication by the public network 40 are interrupted due to the cancellation of the contract with the business operator. Is input, the passcode input screen W1 shown in FIG. 4 and the QR code display screen W2 shown in FIG. 5 are displayed on the display 25.

The passcode input screen W1 shown in FIG. 4 is an example of a screen displayed on the user terminal 20A in which the operation input means 24 which is a touch panel and the display 25 are integrated. As shown in FIG. 4, the passcode input screen W1 includes an input unit b1 for inputting a passcode and an execution button b2 for proceeding to the next process after inputting the passcode in the input unit b1. Further, the passcode input screen W1 includes an operation key display unit b3 used for inputting the passcode. The passcode input screen data for displaying the passcode input screen W1 is included in the service program P2.

The QR code display screen W2 shown in FIG. 5 is also an example of a screen displayed on the user terminal 20A in which the operation input means 24 and the display 25 are integrated, as in FIG. As shown in FIG. 5, on the QR code display screen W2, the QR code D9 is displayed on the QR code display unit b4. The QR code display screen data for displaying the QR code display screen W2 is included in the service program P2. Further, after the QR code D9 generated by the QR code changing means 21d described later is added to the QR code display screen data included in the service program P2, the QR code display screen W2 is displayed on the display 25.

When the first passcode D6 is input via the operation input means 24, the encryption means 21c inputs encrypted data including the token code D4 stored in the storage device 22 and the input first passcode D6. Generate. At this time, the encryption means 21c uses the public key D5 stored in the storage device 22 to encrypt the data including the token code D4 and the first pass code D6 to obtain the encrypted data D8.

The QR code changing means 21d converts the encryption data D8 generated by the encryption means 21c into the QR code D9. Further, the QR code changing means 21d outputs the generated QR code D9 to the display processing means 21b. That is, in the old terminal 20A, by converting the token code D4 and the first pass code D6 into code data such as a QR code, it can be provided in a format that can be easily acquired by another terminal.

《New terminal》
The CPU 21 of the user terminal 20B, which is a new terminal, executes the service program P2 stored in the storage device 22 for the migration procedure, so that the storage processing means 21a, the display processing means 21b, the acquisition means 21e, and the transmission processing means are executed. The process as 21f is executed.

The storage processing means 21a decodes the QR code D9 acquired by the acquisition means 21e described later, and stores the decrypted encrypted data D8 in the storage device 22.

The display processing means 21b receives a request signal requesting a migration procedure via the operation input means 24 after the communication by the Internet line 30 and the communication by the public network 40 are opened due to the contract with the business operator. Then, the QR code acquisition screen W3 and the passcode input screen W1 shown in FIG. 4, which will be described later, are displayed on the display 25 using FIG. Further, the display processing means 21b displays on the display the determination result of the success or failure of the migration received from the service providing server 10.

The QR code acquisition screen W3 shown in FIG. 6 is also an example of a screen displayed on the user terminal 20B in which the operation input means 24 and the display 25 are integrated, as in FIGS. 4 and 5. As shown in FIG. 6, the QR code acquisition screen W3 includes an acquisition unit b5 for acquiring the QR code D9 displayed on the display 25 of the old terminal 20A. The acquisition unit b5 displays an image acquired by the camera 28, and when the acquisition unit b5 displays the QR code display unit b4 displayed on the display 25 of the old terminal 20A, the QR code displayed here is displayed. Can be acquired as image data by the camera 28. The QR code acquisition screen data for displaying the QR code acquisition screen W3 is included in the service program P.

The passcode input screen W1 displayed on the new terminal 20B is also the same as the screen displayed on the old terminal 20A described above using FIG.

When the QR code acquisition screen W3 is displayed on the display 25, the acquisition means 21e acquires the QR code D9 included in the QR code display screen W1 displayed on the display 25 of the old terminal 20A via the camera 28. That is, in the new terminal 20B, the information necessary for migration can be acquired by an easy method of image acquisition instead of the method of character input by the user. As another example, a method of transmitting / receiving code data including necessary information between the old terminal 20A and the new terminal 20B by using wireless communication such as Bluetooth (registered trademark) or ultrasonic wave can be considered. In this case, although security measures are taken to transmit the encrypted code data, there is a risk that the code data will be acquired by another terminal existing near the old terminal 20A and the new terminal 20B. Therefore, it is considered that the method of using the acquisition of image data is safer in terms of security than the method of using wireless communication.

In the transmission processing means 21f, when the acquisition means 21e acquires the QR code D9 and the second pass code D10 is input via the operation input means 24, the encrypted data D8 in which the QR code D9 is decrypted and the second pass Data including the code D10 and the terminal identifier D11 of the new terminal 20B is transmitted to the service providing server 10.

<Migration process>

The service providing server 10 adds the data received in step S1 to the user data 12a and registers it (S2). Further, the service providing server 10 transmits the token code D4 and the public key D5 issued to the registered user to the old terminal 20A (S3).

The old terminal 20A stores the token code D4 and the public key D5 received from the service providing server 10 in the storage device 22 (S4).

After that, after the contract with the business operator is canceled and the connection with the network 30 and the public network 40 is disconnected, when the operation signal for starting the migration procedure is input, the old terminal 20A displays the display 25 as a migration screen. The passcode input screen W1 is displayed (S5).

When the first pass code D6 is input via the operation input means 24 (S6), the old terminal 20A steps the token code D4 stored in the storage device 22 and the first pass code D6 input in step S6. The public key received in S3 is used to encrypt the encrypted data D8 (S7).

After that, the old terminal 20A converts the encrypted data D8 into the QR code D9 (S8), and displays the QR code display screen W2 including the converted QR code D9 on the display 25 (S9).

In the new terminal 20B, which has been contracted with the business operator and the connection with the network 30 and the public network 40 has been started, when the operation signal for starting the migration procedure is input, the QR code acquisition screen W3 is displayed on the display 25 as the migration screen. Display (S10).

When the QR code D9 displayed in step S9 is acquired via the camera 28 (S11), the new terminal 20B decodes the acquired QR code D9 and converts it into encrypted data D8 (S12).

Further, in the new terminal 20B, the passcode input screen W1 is displayed on the display 25, and the second passcode D10 is input (S13).

The service providing server 10 decrypts the encrypted data D8 received from the new terminal 20B with the private key corresponding to the public key used in the encryption in step S7 (S15).

Subsequently, the service providing server 10 compares the first pass code D6 included in the encrypted data D8 decrypted in step S15 with the second pass code D10 received in step S12, and determines whether or not the migration is successful. Judgment (S16).

After that, the service providing server 10 transmits the determination result in step S16 to the new terminal 20B (S17).

Further, the new terminal 20B displays the determination result received in step S17 on the display 25.

Further, the service providing server 10 updates the user data 12a when it is determined in step S17 that the migration is successful (S19).

Further, the old terminal 20A deletes the data used in the service providing system 1 at the timing when the migration is completed (for example, the timing when a predetermined time has elapsed after displaying the QR code in step S9) (S20).

As described above, in the service providing system 1 according to the embodiment, even when the old terminal 20A is canceled and the network 30 is no longer connected, the input is input by the old terminal 20A as shown in FIG. 7A. As shown in FIG. 7B, the created first passcode and token code can be provided to the newly contracted new terminal 20B as a QR code. The new terminal 20B acquires the token code and the first passcode by acquiring the QR code, and as shown in FIG. 7C, combines the newly input second passcode with the service providing server. Send. Further, as shown in FIG. 7D, the service providing server 10 executes the migration procedure using the passcode transmitted from the new terminal 20B. As a result, the user can easily acquire necessary data from the old terminal 20B on the new terminal 20B and proceed with the migration without complicated procedures such as character input. The network 30 is a network 30 provided by a contracted terminal 20 provider, and does not consider, for example, a communication network such as Wi-Fi that can be freely set by an individual user.
