Description

The present invention relates to a mobile device, an information processing method, and a program, and more particularly, to a mobile device, an information processing method, and a program that allow electronic money to be exchanged easily.

  In recent years, mobile phones equipped with non-contact IC chips such as FeliCa (registered trademark) are becoming popular. As a result, the user can make payment at the time of product purchase by simply holding the mobile phone over the reader / writer installed in the counter of the store. For example, when the user holds his / her mobile phone over the reader / writer, the balance of electronic money stored in the non-contact IC chip is rewritten in accordance with a command transmitted from the reader / writer.

  In recent years, various proposals have been made to mount a reader / writer itself in a mobile phone instead of a non-contact IC chip that performs processing in response to an inquiry from the reader / writer. As a result, the user brings his / her mobile phone (a mobile phone equipped with a reader / writer) close to another person's mobile phone equipped with a non-contact IC chip, for example, the electronic money stored in his / her mobile phone. It can be transmitted to the other party's mobile phone, that is, electronic money can be raised.

A technique for exchanging electronic money with other portable terminals is disclosed in Patent Document 1. Depending on the technique disclosed in Patent Literature 1, the user can set the purpose of use, the transmission destination of electronic money, and the like in advance, and transmit the electronic money to the terminal of the transmission destination. Further, payment using electronic money is disclosed in Patent Document 2.

  However, such a function that electronic money can be exchanged just by bringing your mobile phone close to another person's mobile phone is a useful function in itself, but at the same time has a security problem. It is also a function. Specifically, there is a possibility that important data such as electronic money may be transmitted to a third party without the user's knowledge.

  Therefore, every time you try to send e-money etc., you can ask the user to enter a password and start sending data only when the entered password is valid. In this case, although security is enhanced, convenience is lost due to the time and effort required to enter a password.

  For example, when a parent wants to send electronic money from his mobile phone to his child's mobile phone, it can be easily done without entering a troublesome password if it is several hundred to several thousand yen. In addition, it is common to realize transmission of electronic money.

  The present invention has been made in view of such a situation. For example, electronic money can be exchanged easily.

According to the present invention, electronic money can be exchanged easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration example of a communication system according to an embodiment of the present invention.

  The communication system shown in FIG. 1 includes a mobile phone 1 and a mobile phone 2, and both the mobile phone 1 and the mobile phone 2 are equipped with an application for managing electronic money (electronic money management application).

  In the example of FIG. 1, as indicated by the dotted line, the mobile phone 1 and the mobile phone 2 each have a non-contact IC chip 1A and a non-contact IC chip 2A built therein, and the non-contact IC chip 1A and the non-contact IC chip. Electronic money (data representing electronic money) is stored in the 2A flash memory. In the example of FIG. 1, the mobile phone 1 further includes a reader / writer 1B that can read data from an external non-contact IC chip or write data to the non-contact IC chip. The non-contact IC chip 1A and the reader / writer 1B can be realized by a single chip.

  The operation of the non-contact IC chip 1A and the reader / writer 1B is controlled by the electronic money management application of the mobile phone 1, and the operation of the non-contact IC chip 2A is controlled by the electronic money management application of the mobile phone 2.

  In the communication system of FIG. 1 having such a configuration, for example, the function of the user of the mobile phone 1 transmits the electronic money management application function (mode) of the mobile phone 1 to another user's device. 1, when the cellular phone 2 is placed close to the cellular phone 1 as shown in FIG. 1, the electronic money management application of the cellular phone 1 controls the reader / writer 1B. The identification information (identification information (ID) assigned to the mobile phone 2) stored in the contact IC chip 2A is read.

  That is, when the cellular phone 2 comes close, a command for instructing to read the identification information from the flash memory and returning it is transmitted from the reader / writer 1B of the cellular phone 1 and received by the non-contact IC chip 2A of the cellular phone 2. The The non-contact IC chip 2A that has received the command executes the command, and an ID stored in the non-contact IC chip 2A (flash memory of the non-contact IC chip 2A) is returned to the reader / writer 1B.

  When the ID is read, the electronic money management application of the mobile phone 1 refers to the managed device information, and when the mobile phone 2 transmits electronic money to the mobile phone 2 based on the ID of the mobile phone 2, It is determined whether or not it is registered as a device that requires password authentication.

  As will be described in detail later, the device information is information including information indicating whether or not authentication with a password is required (whether authentication is necessary or not) when electronic money is transmitted with each device as a transmission destination. The necessity is managed in association with the ID of the device.

  When the electronic money management application of the mobile phone 1 determines that the mobile phone 2 is a device that does not require authentication when transmitting the electronic money by using the device information as a transmission destination, the reader / writer 1B And a predetermined amount of electronic money stored in the non-contact IC chip 1A is transmitted to the mobile phone 2.

  In the non-contact IC chip 2A of the mobile phone 2 that has received the command, the balance of the stored electronic money is rewritten (rewritten so as to increase by the amount transmitted from the mobile phone 1). The electronic money is transmitted from the mobile phone 1 to the mobile phone 2, that is, the user of the mobile phone 1 can give the electronic money to the user of the mobile phone 2.

  As described above, the user of the mobile phone 1 registers in advance that password authentication is not required when sending electronic money to the mobile phone 2, thereby setting the amount of electronic money to be sent. The electronic money can be easily transmitted to the mobile phone 2 simply by bringing the mobile phone 2 closer to the mobile phone 2.

  Further, when a device other than the mobile phone 2 is brought closer, depending on the registered contents, it is determined that authentication by a password is necessary based on the ID obtained from the other device. It is possible to prevent electronic money from being transmitted without permission to devices that the user of the mobile phone 1 does not permit without being noticed by the user. When a device registered as requiring a password is brought closer, the electronic money management application of the mobile phone 1 prompts the user to enter the password and confirms that the entered password is valid For the first time, electronic money is transmitted to the device.

  As described above, the user of the mobile phone 1 can register the necessity of authentication with a password when transmitting electronic money for each device (for each partner to be given).

  The operation of the mobile phone 1 that determines whether or not authentication is necessary and transmits electronic money will be described later with reference to a flowchart.

  FIG. 2 is a block diagram illustrating a functional configuration example of the mobile phone 1.

  At least a part of each functional unit shown in FIG. 2 is realized by an electronic money management application being executed by a CPU (Central Processing Unit) of the mobile phone 1.

  The communication control unit 11 controls communication performed with a device (for example, the non-contact IC chip 2A of the mobile phone 2) within the reach of the electromagnetic wave by controlling the reader / writer 1B and transmitting the electromagnetic wave. To do.

  For example, when the function of transmitting electronic money to another device is set, the communication control unit 11 performs polling for searching for a communicable device, and detects a communicable device. Read the ID from the contact IC chip. The ID read by the communication control unit 11 is output to the device information management unit 13.

  In addition, when the electronic money management unit 12 instructs the communication control unit 11 to transmit a predetermined amount of electronic money, the communication control unit 11 transmits the amount of electronic money. Transmission of electronic money is realized by transmitting a command for increasing the balance by the amount set by the user of the mobile phone 1 and rewriting it to the contactless IC chip of the transmission destination device. Also, the balance obtained by reading the balance of electronic money stored in the non-contact IC chip of the adjacent device once by the mobile phone 1 and adding to the balance by the amount set by the user of the mobile phone 1 This is realized by transmitting a command instructing rewriting of the balance to the non-contact IC chip.

  The electronic money management unit 12 manages electronic money stored in the contactless IC chip 1A. For example, when the electronic money management unit 12 is notified from the device information management unit 13 that the electronic money transmission destination device has been confirmed to be a device that does not require password authentication, or Although the device is required to be authenticated by a password, the amount entered by the user when the device information management unit 13 is notified that the password entered by the user is valid. The communication control unit 11 is instructed to transmit the electronic money.

  The device information management unit 13 manages device information stored in the device information database 14.

  For example, when the ID read from the adjacent device is supplied from the communication control unit 11, the device information management unit 13 determines that the device currently in proximity is based on the supplied ID. When sending electronic money as a destination, it is judged whether it is registered as a device that requires password authentication by referring to the device information. The money management unit 12 is notified.

  In addition, when the device information management unit 13 determines that the device that is in close proximity is registered as a device that requires password authentication when transmitting electronic money using the device as a transmission destination, And whether or not the entered password is valid is determined. When it is determined that the input password is valid, the device information management unit 13 notifies the electronic money management unit 12 of the fact and causes the electronic money to be transmitted.

  The device information stored in the device information database 14 includes a password registered in advance by the user as information on a device that requires authentication using a password.

  FIG. 3 is a diagram illustrating an example of device information.

  As shown in FIG. 3, whether or not authentication with a password is necessary and password authentication when password authentication is necessary are managed in association with the ID of the device.

  In the example of FIG. 3, information on devices to which IDs “001” to “003” are assigned is registered, and the device to which the ID “001” is assigned transmits electronic money using the information as a transmission destination. It is considered as a device that does not require password authentication.

  A device to which an ID of “002” is assigned is a device that needs to be authenticated by a password when transmitting electronic money using the ID as a transmission destination, and the password is “1234”. The password is registered by the user of the mobile phone 1, and a different password may be registered for each device that requires authentication by the password, or one password may be registered for all devices that require authentication by the password. May be registered.

  A device to which an ID of “003” is assigned is a device that does not require password authentication when electronic money is transmitted to the device.

  Returning to the description of FIG. 2, the device information management unit 13 manages registration or update of device information including such information.

  The device information database 14 stores device information as shown in FIG.

  Next, processing of the cellular phone 1 that transmits electronic money will be described with reference to the flowcharts of FIGS. 4 and 5.

  In step S1, the CPU of the mobile phone 1 activates an electronic money management application in accordance with an instruction from the user, and proceeds to step S2, where the function of the electronic money management application is a function of giving electronic money to a person, that is, contactless. The electronic money stored in the IC chip 1A is changed to a function of transmitting to other devices. An operation for starting the electronic money management application and an operation for selecting a function for giving electronic money to a person are performed on a predetermined menu screen.

  In step S <b> 3, for example, the electronic money management unit 12 displays an input screen on a display provided in the mobile phone 1, and determines the amount of electronic money to be transmitted according to the input by the user. For example, the user can input the amount of electronic money to be transmitted by operating a button such as a numeric keypad provided on the surface of the mobile phone 1. When the amount to be transmitted is input, a message for urging the mobile phone 1 to hold a device to which electronic money is to be transmitted is displayed on the display of the mobile phone 1.

  In step S4, the communication control unit 11 controls the reader / writer 1B to start polling, and then proceeds to step S5 to determine whether there is a response from another device having a non-contact IC chip within the electromagnetic wave reachable range. It is determined whether or not another device (for example, the mobile phone 2) is held over the mobile phone 1.

  If it is determined in step S5 that no other device is held over, communication control unit 11 returns to step S4 and continues polling until it is determined that the device is held over. If the communication control unit 11 determines in step S5 that there is another response, the communication control unit 11 proceeds to step S6.

  In step S6, the communication control unit 11 transmits a command for instructing to read back and return the ID from the reader / writer 1B to the device (eg, the non-contact IC chip 2A of the mobile phone 2). Then, by executing it, the ID of the device being held is obtained. The acquired ID is output to the device information management unit 13.

  In step S7, the device information management unit 13 refers to the device information stored in the device information database 14, confirms the registration status of the acquired ID, proceeds to step S8, and whether the same ID is registered. Determine whether or not.

  In step S8, if the device information management unit 13 determines that the ID acquired from the existing device is registered, the device information management unit 13 proceeds to step S9, in which the device uses the electronic money as a transmission destination. When transmitting, it is determined whether or not it is registered as a device that does not require password authentication (whether or not “unnecessary” is registered in the password authentication required / unnecessary column of the device information).

  If the device information management unit 13 determines in step S9 that the currently held device is registered as a device that does not require password authentication when transmitting electronic money using it as a transmission destination, The electronic money management unit 12 is notified.

  In step S10, the electronic money management unit 12 outputs the amount of electronic money input in step S3 to the communication control unit 11, and transmits it to the device being held. For example, when the electronic money transmission destination device notifies that the electronic money balance has been successfully rewritten, the electronic money management unit 12 uses the electronic money balance stored in the non-contact IC chip 1A. Is rewritten by reducing the amount sent. Thus, when the mobile phone 2 is held over, the user of the mobile phone 1 can give electronic money to the user of the mobile phone 2.

  On the other hand, if the device information management unit 13 determines in step S8 that the acquired ID is not registered, the process proceeds to step S11, where the device that is currently held is the first partner to which electronic money is sent. This is notified to the user by displaying a predetermined message on the display.

  In step S12, the device information management unit 13 requests the user to input a password. That is, when the first device as the electronic money transmission destination is held over, the user is required to input a password to confirm that electronic money will be transmitted from now on. Is prevented from being automatically transmitted.

  When the password is input, the process proceeds to step S13, and the device information management unit 13 determines whether the input password is valid (whether it matches the password registered in advance), If it is determined to be valid, the process proceeds to step S14. If it is determined in step S13 that the input password is not valid, the process ends.

  If it is determined in step S9 that the currently held device is registered as a device that requires password authentication when transmitting electronic money using it as a transmission destination, the process proceeds to step S12, and the same. In addition, the user is required to input a password.

  When the password is input in response to the request, in step S13, the device information management unit 13 refers to the password stored in the device information database 14 (the password included in the device information of the currently held device). Then, it is determined whether or not the input password is valid. If it is determined that the password is valid, the process proceeds to step S14.

  If it is determined in step S13 that the input password is not valid, the process is not terminated immediately, and there is a possibility that the user may input a password incorrectly. Only when the password is allowed to be entered, and the password is still not valid, the process may be terminated.

  In step S <b> 14, the device information management unit 13 displays a screen for selecting whether or not to register the currently held device as a device that does not require password authentication, and inquires the user.

  In step S15, the device information management unit 13 determines whether or not the user has answered that the device is registered as a device that does not require authentication.

If the device information management unit 13 determines in step S15 that there is a reply to register as a device that does not require authentication, the device information management unit 13 proceeds to step S16, and registers the device that is currently present as a device that does not require authentication. (Register “Unnecessary” in the column of password authentication required / unnecessary in device information) Thereafter, after electronic money is transmitted in step S10, the process is terminated.

On the other hand, if the device information management unit 13 determines in step S15 that there is an answer to register as a device that requires authentication, the device information management unit 13 proceeds to step S17, and replaces the currently held device with the electronic money. When it is set as the transmission destination, it is registered as a device that needs to be authenticated ("Required" is registered in the password authentication required / unnecessary column of the device information), and after electronic money is transmitted in step S10, processing is performed. Terminate. As a result, even when the same device is held over again, the user is required to input a password.

  Through the above processing, the user of the mobile phone 1 can easily transmit electronic money to a device that has been registered in advance as a device that does not require authentication, while ensuring both security and convenience.

  In the above, the case where the data to be transmitted is electronic money has been described. However, the same processing is performed to ensure security even when various other data such as text, image, audio, or video data is transmitted. However, it is possible to easily transmit such data.

  In the above description, the device information is managed by the electronic money management application, which is one application for managing electronic money. However, for each type of data to be transmitted or for each application that manages the device, Information may be managed, whereby the necessity of password authentication may be managed. For example, when an image taken with the mobile phone 1 is transmitted to a friend's mobile phone (by an image data transfer application), the password input is omitted, and when an electronic money is transmitted (by an electronic money management application), the password is omitted. It may be possible to make a setting such that the input of is mandatory. The same applies to data relating to text, images, sounds or videos other than images.

  Even when sending electronic money, when sending a relatively small amount of electronic money, such as several hundred yen, the password entry is omitted, and a relatively large amount of electronic money, such as tens of thousands of yen, is sent. When transmitting the password, it may be determined whether or not the authentication with the password is necessary based on the amount to be transmitted. In this case, the amount (threshold value) that serves as a reference for determining whether or not password authentication is necessary is set by the user, for example.

  The series of processes described above can be executed by hardware, but can also be executed by software. In this case, the mobile phone 1 that executes the software is constituted by, for example, a personal computer as shown in FIG.

  In FIG. 6, the CPU 51 executes various processes according to a program stored in a ROM (Read Only Memory) 52 or a program loaded from a storage unit 58 to a RAM (Random Access Memory) 53. The RAM 53 also appropriately stores data necessary for the CPU 51 to execute various processes.

  The CPU 51, ROM 52, and RAM 53 are connected to each other via a bus 54. An input / output interface 55 is also connected to the bus 54.

  The input / output interface 55 includes an input unit 56 including a keyboard and a mouse, a display including an LCD (Liquid Crystal Display), an output unit 57 including a speaker, a storage unit 58 including a hard disk, and a network. A communication unit 59 for performing all communication processes is connected.

  A drive 60 is also connected to the input / output interface 55 as necessary. A removable medium 61 composed of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately attached to the drive 60, and a computer program read therefrom is installed in the storage unit 58 as necessary.

  When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a network or a recording medium into a general-purpose personal computer or the like.

  As shown in FIG. 6, the recording medium is distributed to provide a program to the user separately from the apparatus main body, and includes a magnetic disk (including a flexible disk) on which the program is recorded, an optical disk (CD- Removable media 61 composed of ROM (compact disk-read only memory), DVD (digital versatile disk), magneto-optical disk (including MD (registered trademark) (mini-disk)), or semiconductor memory In addition, it is configured by a ROM 52 on which a program is recorded and a hard disk included in the storage unit 58 provided to the user in a state of being pre-installed in the apparatus main body.

  In the present specification, each step includes not only processing performed in time series according to the described order but also processing executed in parallel or individually, although not necessarily performed in time series.

  Further, in this specification, the system represents the entire apparatus composed of a plurality of apparatuses.
