[0001] The present invention relates to a technique for communication connection in short-range wireless communication, and more particularly to an information processing device and an information processing system that promote pairing with an information processing terminal carried by a user. [Background technology]

[0002] 2. Description of the Related Art In recent years, in car navigation systems, information linkage has progressed using wireless communication between an information processing terminal such as a smartphone carried by a user and an information processing device such as a navigation device.

[0003] The smartphone and the navigation device are connected by short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi. When the information processing device and the information processing terminal are connected by Bluetooth (registered trademark) or the like, a pairing process is performed to register each other's setting information. The information processing device and the information processing terminal perform authentication to prevent erroneous connection or to improve security through the pairing process.

[0004] However, the information processing device and the information processing terminal may require the user to go through complicated procedures depending on the mechanism of the pairing process, so it cannot be said that the user fully utilizes the information linkage by communicatively connecting the information processing terminal and the information processing device.

[0005] Incidentally, a configuration is known in which a two-dimensional barcode is read from a mobile terminal and linked to a server in a session-less state to provide a service (Patent Document 1). Patent Document 1 does not disclose an information processing system that performs pairing processing between an information processing terminal and an information processing device.

[0011] <Configuration of Information Processing System 10> FIG. 1 shows a configuration of an information processing system 10 according to an embodiment. The information processing system 10 includes an information processing device 2 and an information processing terminal 3. The information processing device 2 is mounted on, for example, a vehicle 1. The vehicle 1 may be, for example, an automobile or a motorcycle. The information processing device 2 may be, for example, a navigation device. The information processing terminal 3 is a terminal carried by a user inside the vehicle 1. The information processing terminal 3 may be, for example, a smartphone, a tablet terminal, or a notebook computer. In the information processing system 10, the information processing device 2 and the information processing terminal 3 are configured to be able to communicate with each other via a short-range wireless communication network 4. The short-range wireless communication network 4 may be, for example, a network using Bluetooth (registered trademark).

[0012] The information processing system 10 is configured so that the pairing process between the information processing device 2 and the information processing terminal 3 is automatically completed when the information processing terminal 3 simply reads the two-dimensional code 25 output by the information processing device 2. As a result, the information processing system 10 allows the user to relatively easily set up a communication connection between the information processing device 2 and the information processing terminal 3 without going through complicated connection procedures.

[0013] Information processing device 2 The information processing device 2 includes a first communication unit 21, a first input / output unit 22, a first storage unit 23, and a first control unit 24. In the following, the information processing device 2 will be described as an in-vehicle navigation device.

[0014] The first communication unit 21 is configured to be able to communicate with the information processing terminal 3 via the short-range wireless communication network 4. The first communication unit 21 can transmit radio waves for short-range wireless communication to the information processing terminal 3. The first communication unit 21 can receive radio waves for short-range wireless communication from the information processing terminal 3.

[0015] The first input / output unit 22 is an interface for inputting and outputting information. The first input / output unit 22 includes an input device and an output device. Examples of the input device include a remote controller, a touch panel, or a microphone. Examples of the output device include a display or a speaker. Examples of the display include a liquid crystal display device and an EL (Electro Luminescence) display device. For example, information related to a navigation search is input to the first input / output unit 22. For example, the first input / output unit 22 outputs guidance information related to the position of the vehicle 1, a map, and route guidance to a destination.

[0016] Moreover, the first input / output unit 22 is an interface that outputs the two-dimensional code 25. For example, the two-dimensional code 25 is output from an output device. The output device is a display device on which the two-dimensional code 25 is displayed. The two-dimensional code 25 is preferably, for example, a matrix-type QR code (registered trademark). The two-dimensional code 25 is not limited to only a QR code (registered trademark). Other two-dimensional codes are also applicable, and other types of matrix-type two-dimensional codes or stack-type two-dimensional codes may also be used. As shown in FIG. 2A, the two-dimensional code 25 includes, for example, the address of the information processing device 2 and a public key generated by the information processing device 2. Examples of the address of the information processing device 2 include a MAC (Media Access Control address) address and a BD (Bluetooth device address) address.

[0017] The first storage unit 23 is configured with, for example, a Read Only Memory (ROM), a Read Access Memory (RAM), or a Hard Disk Unit (HDD). The first storage unit 23 stores, for example, map information.

[0018] The first storage unit 23 stores the first connection information 26 based on the connection information transmitted from the information processing terminal 3. For example, as shown in FIG. 2B, the first connection information 26 includes the address of the information processing terminal 3 and a public key generated by the information processing terminal 3. Examples of the address of the information processing terminal 3 include a Media Access Control address (MAC) address and a Bluetooth device address (BD) address. The first connection information 26 is connection information included in the short-range wireless radio waves transmitted by the information processing terminal 3 during pairing processing between the information processing device 2 and the information processing terminal 3. When the information processing device 2 and the information processing terminal 3 have successfully authenticated each other during the pairing processing, the information processing device 2 is configured to store the first connection information 26 in the first storage unit 23. After storing the first connection information 26 in the first storage unit 23, the information processing device 2 uses the first connection information 26 for communication connection with the information processing terminal 3.

[0019] The first control unit 24 is composed of a CPU (Central Processing Unit) and a memory. The first control unit 24 is configured to be able to control the first communication unit 21, the first input / output unit 22, and the first storage unit 23. The first control unit 24 executes various processes by transferring various data, performing various calculations, and temporarily storing data. For example, the first control unit 24 executes processes related to navigation. In addition, the first control unit 24 executes a pairing process when establishing a communication connection with the information processing terminal 3.

[0020] The first storage unit 23 stores a first program for implementing the functions of the first control unit 24 of the information processing device 2. The first program is stored in a storage device configured, for example, of the information processing device 2's Read Only Memory (ROM), Read Access Memory (RAM), or Hard Disk Unit (HDD). The first program may be recorded in a computer-readable recording medium. Examples of computer-readable recording media include a hard disk, a flexible disk, a Compact Disc Read Only Memory (CD-ROM), a Magneto Optical Disk (MO), and a Digital Versatile Disc Read Only Memory (DVD-ROM). The first program executed in the information processing device 2 may be distributed via a communication network.

[0021] Information processing terminal 3 The information processing terminal 3 includes a second communication unit 31, a second input / output unit 32, a second storage unit 33, and a second control unit 34. In the following, the information processing terminal 3 will be described as a smartphone.

[0022] The second communication unit 31 is configured to be able to communicate with the information processing device 2 via the short-range wireless communication network 4. The second communication unit 31 is configured to be able to transmit radio waves of the short-range wireless communication to the information processing device 2. The second communication unit 31 is configured to be able to receive radio waves of the short-range wireless communication from the information processing device 2.

[0023] The second input / output unit 32 is an interface for inputting and outputting information. The second input / output unit 23 includes a terminal input device and a terminal output device. Examples of the terminal input device include a touch panel, a camera, and a microphone. The terminal output device includes, for example, a display and a speaker. Examples of the display include a liquid crystal display device and an EL (Electro Luminescence) display device. The camera is configured to be able to read the two-dimensional code 25 output to the display device of the information processing device 2. In other words, the second input / output unit 32 is also an acquisition unit that acquires information indicated by the two-dimensional code 25.

[0024] The second storage unit 33 is configured, for example, with a ROM (Read Only Memory), a RAM (Read Access Memory), or a HDD (Hard Disk Unit). The second storage unit 33 stores second connection information 35. The second storage unit 33 also stores a program 36. The program 36 is also referred to as a second program.

[0025] 2C, the second connection information 35 includes, for example, the address of the information processing device 2 and a public key generated by the information processing device 2. Examples of the address of the information processing device 2 include a Media Access Control (MAC) address and a Bluetooth device (BD) address. That is, the second connection information 35 is information included in the two-dimensional code 25 read by the camera of the information processing terminal 3. When the information processing device 2 and the information processing terminal 3 have successfully authenticated each other in the pairing process, the information processing terminal 3 stores the second connection information 35 in the second storage unit 33, and then uses the second connection information 35 for communication connection with the information processing device 2.

[0026] The program 36 is, for example, a dedicated application program for facilitating the setting of a communication connection via short-distance wireless communication with the information processing device 2. The program 36 is configured, for example, to start a camera to capture an image of the two-dimensional code 25 and acquire information included in the captured two-dimensional code 25, that is, the address of the information processing device 2 and the public key of the information processing device 2. The program 36 is configured, for example, to start a function of short-distance wireless communication, transmit a public key generated by the information processing terminal 3 to the information processing device 2 according to the address of the information processing device 2 included in the two-dimensional code 25, and execute a pairing process.

[0027] The second control unit 34 is composed of a CPU (Central Processing Unit) and a memory. The second control unit 34 is configured to be able to control the second communication unit 31, the second input / output unit 32, and the second storage unit 33. The second control unit 34 executes various processes by transferring various data, performing various calculations, and temporarily storing data. For example, the second control unit 34 executes a program 36 to obtain information included in the two-dimensional code 25, and executes a pairing process when connecting for communication with the information processing device 2.

[0028] The program 36 is stored in a storage device constituted by, for example, a ROM (Read Only Memory), a RAM (Read Access Memory), or a HDD (Hard Disk Unit) of the information processing terminal 3. The program 36 may be recorded in, for example, a computer-readable recording medium. Examples of computer-readable recording media include a hard disk, a flexible disk, a CD-ROM (Compact Disc Read Only Memory), a MO (Magneto Optical Disk), and a DVD-ROM (Digital Versatile Disc Read Only Memory). The program 36 may be distributed via a communication network.

[0029] <Operation of Information Processing System 10> Next, the pairing process of the information processing system 10 will be described with reference to Figs. 3 and 4. The flow of the pairing process executed by the information processing device 2 will be described with reference to the flowchart shown in Fig. 3. The flow of the pairing process executed by the information processing terminal 3 will be described with reference to the flowchart shown in Fig. 4. Hereinafter, the pairing process executed by the information processing device 2 will be referred to as a first pairing process, and the pairing process executed by the information processing terminal 3 will be referred to as a second pairing process. Furthermore, steps in the flowchart are indicated by S. Note that, as a premise, the information processing terminal 3 is in a state in which the program 36 is running.

[0030] First pairing process The first pairing process is executed when the information processing device 2 is started up, and periodically at predetermined time intervals after the information processing device 2 is started up.

[0031] As shown in Fig. 3, the information processing device 2 judges whether or not it has received radio waves for short-distance wireless communication transmitted by the information processing terminal 3 (S10). The information processing device 2 executes a process for displaying the two-dimensional code 25 (S30 to S50) when (1) it has not received radio waves for short-distance wireless communication (S10: NO), or (2) it has received radio waves for short-distance wireless communication (S10: YES) but the first storage unit 23 does not have the same first connection information 26 as the information included in the received radio waves (S20: NO). Hereinafter, the above cases (1) when it has not received radio waves for short-distance wireless communication and (2) when it has received radio waves for short-distance wireless communication but the first storage unit 23 does not have the same first connection information 26 as the information included in the received radio waves are referred to as cases where the two-dimensional code display condition is satisfied. In other words, when the two-dimensional code display condition is met, the information processing device 2 generates a public key (S30), generates a two-dimensional code 25 including the address of the information processing device 2 and the generated public key (S40), and displays the generated two-dimensional code 25 on the display device of the first input / output unit 22 (S50).

[0032] Here, (1) a case where short-range wireless communication radio waves are not received includes, for example, a case where the short-range wireless function of the information processing terminal 3 carried by the user is stopped while the user is inside the vehicle 1. (2) a case where short-range wireless communication radio waves are received, but the first storage unit 23 does not have the same first connection information 26 as the information contained in the received radio waves includes a case where the user activates the short-range wireless function of the information processing terminal 3 carried by the user while inside the vehicle 1, but this is the first time the user has carried this information processing terminal 3 in the vehicle 1.

[0033] After displaying the two-dimensional code 25, the information processing device 2 determines whether or not it has received the public key generated by the information processing terminal 3 based on the radio waves of short-range wireless communication transmitted by the information processing terminal 3 (S60). Note that the radio waves of short-range wireless communication transmitted by the information processing terminal 3 that has read the two-dimensional code 25 contain the address of the information processing terminal 3 and the public key generated by the information processing terminal 3.

[0034] When the information processing device 2 receives from the information processing terminal 3 the public key generated by the information processing terminal 3 (S60: YES), the information processing device 2 executes authentication processing (S70).

[0035] Here, the authentication process is a process in which the information processing device 2 and the information processing terminal 3 exchange public keys generated by each of them, perform an operation to multiply the public key generated by itself with the public key generated by the communication partner, and verify whether the operation values ​​match. That is, specifically, the information processing device 2 transmits the public key generated by itself to the information processing terminal 3, and the information processing terminal 3 transmits the public key generated by the information processing terminal 3 to the information processing device 2. Next, the information processing device 2 performs an operation to multiply the public key generated by itself with the public key transmitted from the information processing terminal 3 to generate a first operation value X1, and transmits the generated first operation value X1 to the information processing terminal 3. Similarly, the information processing terminal 3 performs an operation to multiply the public key generated by itself with the public key transmitted from the information processing device 2 to generate a second operation value X2, and transmits the generated second operation value X2 to the information processing device 2. Finally, the information processing device 2 and the information processing terminal 3 each verify whether the first calculation value X1 and the second calculation value X2 match, and if they match, determine that the authentication has been successful. If the authentication is successful, the first calculation value X1 and the second calculation value X2 are treated as private keys of the information processing device 2 and the information processing terminal 3. Thereafter, the information processing device 2 and the information processing terminal 3 can establish a communication connection without performing a new pairing process by each holding this private key.

[0036] If the authentication process is successful (S80: YES), the information processing device 2 stores the address of the information processing terminal 3 and the public key generated by the information processing terminal 3 as first connection information 26 in the first storage unit 23 (S90), and establishes a communication connection with the information processing terminal 3 based on the first connection information 26 (S100). As a result, the information processing device 2 does not need to perform pairing process with the information processing terminal 3 from the next time onwards.

[0037] On the other hand, if the authentication process fails (S80: NO), the information processing device 2 does not perform connection settings for short-range wireless communication with the information processing terminal 3, and ends the first pairing process.

[0038] Furthermore, when the two-dimensional code display condition is not satisfied, that is, when the information processing device 2 receives radio waves for short-range wireless communication (S10: YES) and has in the first storage unit 23 the first connection information 26 identical to the information contained in the received radio waves (S20: YES), the information processing device 2 establishes a communication connection with the information processing terminal 3 based on the first connection information 26 stored in the first storage unit 23 (S110). In this case, the information processing device 2 does not need to perform a new authentication process to reset the first connection information 26, because the communication partner is the information processing terminal 3 with which it has previously established a communication connection.

[0039] -Second pairing process 4, the second pairing process is a process performed when the information processing terminal 3 reads the two-dimensional code 25 displayed on the information processing device 2. When the information processing device 2 does not display the two-dimensional code 25 and the information processing terminal 3 does not need to read the two-dimensional code 25, the information processing terminal 3 does not perform the pairing process because the information processing terminal 3 has already established a communication connection with the information processing device 2 and the short-range wireless communication function is also activated.

[0040] The information processing terminal 3 uses a camera to capture the two-dimensional code 25 displayed on the information processing device 2, reads the two-dimensional code 25 (S210), and obtains the address of the information processing device 2 and the public key generated by the information processing device 2, which are contained in the read two-dimensional code 25 (S220).

[0041] When the information processing terminal 3 does not have in the second storage unit 33 the second connection information 35 that is the same as the address of the information processing device 2 acquired from the two-dimensional code 25 and the public key generated by the information processing device 2 (S230: NO), the information processing terminal 3 activates the short-range wireless communication function. By activating the short-range wireless communication function, the information processing terminal 3 transmits radio waves for short-range wireless communication (S240), generates a public key (S250), transmits the address of the information processing terminal 3 and the generated public key to the information processing device 2 (S260), and executes authentication processing (S270). The authentication processing is as described in the first pairing processing.

[0042] If the authentication process is successful (S280: YES), the information processing terminal 3 stores the address of the information processing device 2 and the public key generated by the information processing device 2 as second connection information 35 in the second storage unit 33 (S290), and establishes a communication connection with the information processing device 2 based on the second connection information 35 (S300). As a result, the information processing terminal 3 does not need to perform pairing process with the information processing device 2 from the next time onwards.

[0043] On the other hand, if the authentication process fails (S280: NO), the information processing terminal 3 does not perform connection setting for short-range wireless communication with the information processing device 2, and ends the second pairing process.

[0044] Furthermore, when the information processing terminal 3 has in the second storage unit 33 the second connection information 35 that is the same as the address of the information processing device 2 acquired from the two-dimensional code 25 and the public key generated by the information processing device 2 (S230: YES), the information processing terminal 3 activates a short-range wireless communication function to transmit radio waves for short-range wireless communication (S310). The information processing terminal 3 establishes a communication connection with the information processing device 2 based on the second connection information 35 stored in the second storage unit 33 (S320). In this case, the information processing terminal 3 does not need to perform a new authentication process to reset the second connection information because the communication partner is the information processing device 2 with which it has previously established a communication connection.

[0045] As described above, in the information processing system 10, when the information processing device 2 displays the two-dimensional code 25, the information processing terminal 3 can automatically complete the pairing process with the information processing device 2 and set up a communication connection simply by reading the two-dimensional code 25. Therefore, according to the information processing system 10, it is possible to easily set up a communication connection between the information processing terminal 3 and the information processing device 2 in a relatively simple manner. Furthermore, according to the information processing system 10, it is possible to promote the use of the communication connection between the information processing terminal 3 and the information processing device 2.

[0046] That is, in the information processing system 10, it is not necessary for the user to perform complicated operation procedures that have been conventionally required for setting up short-range wireless communication, for example, an operation in which the user opens a setting screen related to a network connection of the information processing terminal 3 and activates the setting for short-range wireless communication. Also, in the information processing system 10, it is not necessary for the user to perform a series of pairing operations, such as an operation of opening a menu setting screen of the information processing device 2, searching for an information processing terminal 3 in which the setting for short-range wireless communication is activated, selecting the information processing terminal 3, and an operation of confirming the PIN code and password issued by the information processing device 2 on the information processing terminal 3. As a result, in the information processing system 10, it is possible to reduce the operational burden on the user in the pairing process.

[0047] Furthermore, the information processing system 10 is configured to display the two-dimensional code 25 only when the two-dimensional code display condition is met, that is, only when the information processing device 2 cannot detect a communication connection with the information processing terminal 3, to prompt the communication connection of the information processing terminal 3. For this reason, the user only needs to read the two-dimensional code 25 when necessary, and the user does not find the work bothersome.

[0048] <Modification> Sound output In the information processing system 10, the information processing terminal 3 is configured to obtain the address and public key of the information processing device 2 via the two-dimensional code 25 output by the information processing device 2. However, instead of or in addition to this, the information processing terminal 3 may be configured to obtain the address and public key of the information processing device 2 via the sound output by the information processing device 2. For example, a digital watermark may be embedded in the data of the inaudible sound output by the information processing device 2, and the address and public key information of the information processing device 2 may be transmitted to the information processing terminal 3. In this case, the program 36 of the information processing device 2 is configured to analyze the data of the inaudible sound obtained via the microphone and obtain the address and public key of the information processing device 2.

[0049] According to this modified example, by using sound, as in the case of using images, it is possible to facilitate a communication connection between the information processing device 2 and the information processing terminal 3, thereby improving the convenience of the user regarding communication settings.

[0050] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made to the embodiments of the present invention without departing from the gist of the present invention, and configurations involving such modifications and changes are also included in the technical scope of the present invention.
