 Data movement method

 Technical field

 TECHNICAL FIELD [0001] The present invention relates to a data movement method when data is exchanged between terminals such as a DVD recorder, a notebook PC, and a mobile phone equipped with a wireless communication function.

 Background art

 [0002] As a method of exchanging data between terminals such as mobile phones, DVD recorders, notebook PCs, etc., NFC (Near, which has become an international standard for Bluetooth and ISOZIEC IS 18092, which are wireless transmission systems using the 4 GHz band. There is a method of moving data using wireless communication functions such as Field Communication.

 [0003] However, terminals equipped with a wireless communication function have the advantage that the terminals do not need to be connected to each other via a communication cable. However, they do not have the same communication function as terminals within a communication area. Makes it possible for any terminal to establish a session.

 [0004] For this reason, when exchanging data between terminals by wireless communication, the user exchanges data in advance so that the data to be exchanged is not intended and may not be transmitted to the terminal by mistake. It is necessary to specify the desired communication partner terminal.

 [0005] In particular, when the data to be exchanged is copyrighted data, electronic money, or the like, data exchange is performed to prevent unauthorized acquisition of the exchange data by the terminal, which should allow communication. It is necessary to confirm whether the communication partner terminal is a legitimate terminal that has been authenticated in advance.

 [0006] Conventionally, as a technique for preventing data transmission to an unintended terminal as described above, for example, a "service providing method" described in Patent Document 1 and a "data processing method" described in Patent Document 2 are known. .

[0007] In the "service providing method" described in Patent Document 1, the proximity communication of the communication partner terminal is performed only when a user terminal equipped with a short-range wireless communication function is brought close to the communication partner terminal to request connection. The terminal is set to the search signal reception mode so that terminals outside the proximity area do not respond to the search signal from the user terminal. [0008] Further, in this "service providing method", after the local communication unit connection information is transmitted by the near field communication unit of the communication partner terminal, the local communication unit of the communication partner terminal is set to the connection request reception mode. Set and acquire the normal connection information transmitted from the near field communication unit of the communication partner terminal, and do not accept connection requests with terminal power.

 [0009] In the "data processing method" described in Patent Document 2, the content data is transferred when content data is also transferred to a memory card even when the mobile phone equipped with a USIM (Universal Subscriber Identity Module) is used. Content identification information for identification is recorded in USIM.

 [0010] In this "data processing method", when content data is to be moved to a mobile phone equipped with a memory card USIM, the content identification information corresponding to the content data is USIM. If it is not recorded in the file, the movement of the content data is prohibited.

[0011] Further, as a portable terminal that can perform writing and reading of information with a very simple user interface, a "communication device" described in Patent Document 3 is known.

The “communication device” described in Patent Document 3 includes an NFC communication device that communicates information by proximity communication, a write button, and a read button.

[0013] And when the mobile terminal also writes information to the external device, the user

Then, with the write button pressed, bring the mobile terminal close to the information provider to about 10 cm.

 [0014] Further, when information is also read out to the mobile terminal by the external device power, the user brings the mobile terminal close to the information providing apparatus to about 10 cm while pressing the read button.

By such an operation, information is automatically transferred between the mobile terminal and the external device.

 Disclosure of the invention

 Problems to be solved by the invention

However, in the “service providing method” described in Patent Document 1, the proximity of the terminal is used. Both the communication unit and the local communication unit are equipped with Bluetooth devices (short-range wireless communication function)! Because there is a need to do this, there is a problem when it comes to high costs!

[0017] For this reason, such a "service providing method" can be applied to a high-end terminal having two types of short-range wireless communication functions using, for example, a combination of Bluetooth and FeliCa (registered trademark). However, it cannot be applied to a terminal that does not have one short-range wireless communication function.

 [0018] In this "service providing method", it is possible to share one Bluetooth device by switching, but in this case, a high-frequency switch for switching the circuit of one Bluetooth device, Therefore, switching control of the high frequency switch is necessary.

 [0019] In the "data processing method" described in Patent Document 2, when data is exchanged between terminals, the content is transferred to the internal memory that one terminal power is not moved to the terminal for each USIM. There are inconveniences that cannot be made.

 That is, in this “data processing method”, content identification information corresponding to content data is recorded, and content cannot be written to the internal memory unless it is a terminal equipped with USIM. Content data cannot be exchanged between terminals by communication.

 [0021] Since the "communication device" described in Patent Document 3 can only confirm the communication partner terminal with which data is exchanged visually, there is a risk that transmission data may be received by an unintended terminal.

 That is, in this “communication terminal”, when data is exchanged between the terminals, the write button and the read button are operated in sequence. By this operation, the communication partner terminal that performs short-distance wireless communication is selected. You cannot select it.

Therefore, in this “communication terminal”, it is necessary for the user himself / herself to visually determine a communication partner terminal that is permitted to transmit data when exchanging data between the terminals.

[0024] For this reason, in this "communication terminal", when an unknown terminal having the same function as that of the communication counterpart terminal is placed in an invisible state in the communication area of the user terminal, this unknown There is a risk of data being sent to the terminal. [0025] It should be noted that in setting software such as a wireless LAN, communication with PCs that do not have the same ID can be restricted by inputting the same ID and keyboard power to each PC.

[0026] However, in this method, in addition to the user's trouble of inputting an ID using a keyboard, an ID is set for each PC in order to perform one-to-one communication with multiple PCs. If you need it! / It can be annoying.

[0027] An object of the present invention is not intended when exchanging data between terminals equipped with a short-range wireless communication function! Data transfer that can prevent data exchange with a terminal by a simple operation. Is to provide a moving method.

 Means for solving the problem

[0028] The data movement method of the present invention is a data movement method in the case where data is exchanged between a transmission side terminal and a reception side terminal having a data read / write function and a wireless communication function to a removable memory card. A receiving-side ID recording step of recording the receiving-side ID of the receiving-side terminal in a memory card that records the transmitting-side ID of the transmitting-side terminal inserted into the receiving-side terminal; and storing the receiving-side ID When a wireless communication session is established with the transmission-side terminal communication partner terminal in which the memory card is inserted, a session is performed only for the communication partner terminal having an ID that matches the reception-side ID read by the memory card force. And a session establishment permission step for permitting establishment of the above.

 The invention's effect

 [0029] According to the present invention, when data is exchanged between terminals equipped with a short-range wireless communication function, I I f blueprint obtained using a memory card in advance and I of a communication terminal requesting data exchange. Since session establishment is permitted only to the communication partner terminal that matches the blueprint, data exchange with an unintended terminal can be prevented with a simple operation.

[0050] The determination unit 206 of the receiving-side terminal 200 determines whether or not the information power is the information of the communication permission target terminal read from the storage unit 301 of the memory card 300 via the contact communication unit 202 and the control unit 203. Determine.

 [0051] The memory card 300 includes a storage unit 301 for storing information and ID control information, which is a storage medium such as an SD memory card configured to be detachable from the transmission side terminal 100 and the reception side terminal 200.

[0052] Next, a process for exchanging data between terminals by the data movement method of this example will be described. I will explain. FIG. 2 is a sequence diagram showing processing when data is exchanged between terminals by the data movement method of the present invention.

As shown in FIG. 2, in the data movement method of this example, when data is exchanged between the transmitting terminal 100 and the receiving terminal 200, the owner of the memory card 300 is first used. User power Insert the memory card 300 into the transmitting terminal 100 in advance.

[0054] Then, in the storage unit 301 of the memory card 300 inserted into the transmission side terminal 100, the transmission side ID, which is the information of the transmission side terminal loo, is stored together with the ID restriction information (step ST201). ).

 Next, the user (or data exchange partner) inserts the memory card 300 storing the transmission side ID of the transmission side terminal 100 into the reception side terminal 200 (step ST202).

[0056] Then, the receiving side terminal 200 reads out and acquires the transmitting side ID of the transmitting side terminal 100 from the inserted memory card 300.

Here, when communication with the receiving side terminal 200 is permitted, the receiving side ID as information on the receiving side terminal 200 is stored in the storage unit 301 of the inserted memory card 300 together with the ID control information. (Step ST203).

[0058] Next, the user inserts memory card 300 extracted from receiving side terminal 200 into his / her transmitting side terminal 100 again (step ST204).

[0059] Then, the transmission side terminal 100 reads the restriction information corresponding to the reception side ID of the reception side terminal 200 from the reinserted memory card 300, and sets (stores) it in a predetermined area of the storage unit 106 (step). ST205).

[0060] Next, the transmitting side terminal 100 presses button 1 (public area button) of the numeric keypad of the operation unit 101 for exchanging data with the receiving side terminal 200 (step ST206).

As a result, transmitting terminal 100 permits reading of data only while the public area button is pressed, and starts a session establishment process with receiving terminal 200 (step ST207).

[0062] When the session establishment process is started between the transmission side terminal 100 and the reception side terminal 200 in this way, the transmission side terminal 100 first sends a reception side ID to the reception side terminal 200. (Step ST208). [0063] Then, the transmitting terminal 100 compares the receiving ID read from the memory card 300 with the ID that also received the partner terminal power (step ST209), and the judging unit 102 determines whether the Judge whether or not they match.

 [0064] Here, the ID that has also received the partner terminal power is the receiver ID of the receiver terminal 200, and the determination unit 102 of the transmitter terminal 100 matches the receiver ID that also read the memory card 300 power in step ST205. If it is determined that this is the case, establishment of a session is permitted for receiving terminal 200 (step ST210).

 [0065] It should be noted that, here, the transmitting terminal 100 confirms the information of the receiving terminal 200. The receiving terminal 100 reads the receiving ID read from the memory card 300 in step ST205 to the receiving terminal 200. It may be sent and the receiving side terminal 200 confirms the information.

 [0066] When the transmission side terminal 100 permits the reception side terminal 200 to establish a session in this way, the reception side terminal 200 issues a read request (or write request) to the transmission side terminal 100 (step) ST211).

 Thereby, the transmitting terminal 100 transmits the data in the public area of the control information storage unit 104 to the receiving terminal 200 in response to the reading request (or writing request) of the receiving terminal 200 ( Step ST212).

 [0068] The data movement method of this example uses, for example, a mobile phone 100A as the transmitting terminal 100, a mobile phone 200A as the receiving terminal 200, and a memory card 300 as shown in FIG. Therefore, it is suitable for exchanging data such as electronic money.

 Further, for example, as shown in FIG. 4, the data movement method of this example includes a DVD recorder 100B as the transmission side terminal 100, a mobile phone 200A as the reception side terminal 200, and a memory card (SD memory card). ) Suitable for exchanging data such as TV video files using 300.

[0070] In addition, as shown in FIG. 5, for example, the data movement method of this example includes a notebook PC 100C as the transmitting terminal 100, a notebook PC 200C as the receiving terminal 200, and a memory card (SD memory card). It is suitable for exchanging data such as document files using 300. [0071] Furthermore, as shown in FIG. 6, for example, as shown in FIG. 6, the data movement method of the present example is a notebook PC 100C as the transmission side terminal 100, a mobile phone 200A as the reception side terminal 200, and a memory card D memory card. This is suitable for exchanging data such as music files using 300.

 In this way, according to the data movement method of the present example, prior to data exchange, the transmission side terminal 100 that is the user terminal and the reception side terminal 200 that is the data exchange partner terminal The memory card 300 is used to exchange mutual ID information.

 [0073] Therefore, in the data movement method of this example, when data is exchanged between terminals equipped with short-range wireless communication such as Bluetooth or NFC, only mutual information is directly exchanged using the memory card 300. With simple operations, it is unintentional! You can prevent data exchange with external terminals.

 [0074] In particular, when secure movement of data is required, such as electronic money, it is generally necessary to put information (ID, password, authentication key) of the other party that is permitted to communicate with the terminal in advance. In the example data movement method, mutual information can be easily exchanged using the memory card 300 without troublesome settings.

 [0075] In addition, according to the data movement method of this example, a memory card already installed in a general terminal

Since 300 uses each other to exchange information, data can be exchanged at low cost.

 [0076] In addition, according to the data movement method of this example, mutual information can be exchanged by a simple operation of inserting the memory card 300 once into the receiving terminal 200 of the data exchange partner. So you don't have to make troublesome settings before data exchange!

 [0077] In addition, in the data movement method of this example, communication partners can be restricted by an intuitive and reliable user operation of inserting a memory card 300 into the receiving terminal 200 in advance, and the receiving terminal 200 can Since the open memory area can be limited by the type of terminal and buttons, data can be exchanged safely and easily.

[0078] In the data transfer method of this example, as information stored in the memory card 300, the I blueprint for identifying the terminal and the ID restriction information (both the transmission source and the transmission destination are OK). I am using it. [0079] As information for identifying a terminal, a permanent fixed ID such as a UIM ID, a terminal serial number, and a telephone number can be used.

[0080] If important information is not passed to the data exchange partner's terminal, a fixed ID that can be changed such as the terminal's nickname or e-mail address is used as ID information for identifying the terminal. Is preferred to use.

[0081] Further, when temporary data exchange is performed with the receiving terminal 200, it is preferable to use a temporary ID such as a random number or a sequence number as ID information for identifying the terminal.

 [0082] HD information for identifying other terminals includes encryption information such as an ID (file name, folder name, address) of an area to be disclosed and an authentication key. In addition, the area to be released should be decided at the beginning.

[0083] ID restriction information includes, for example, the valid period (valid from YY1: MM1: DD1 to YY2: MM2: DD2), valid count (only once), valid data volume (cumulative total 5 MB, maximum 1 MB) ), Valid data type (phone book permission, image not allowed), valid data category (sports, news, etc.).

[0084] In addition, according to the data movement method of this example, public data may be stored in advance in the divided areas of the control information storage unit 104 of the transmitting terminal 100 according to the corresponding terminal. . This makes it possible to prevent virtual copies and original data from being destroyed by publishing virtual divided areas and placing only links to actual data in the areas.

[0085] Further, according to the data movement method of this example, both the button for releasing the access restriction and the terminal for which access is permitted are assigned to the divided areas of the control information storage unit 104 of the transmission side terminal 100. Yes (cancel only when pressed). Then, the divided area may be specified on the user interface, and the access restriction may be released with a single button such as a determination button.

[0086] The memory card 300 may be an IC card!

[0087] Further, the information and control information of the memory card 300 are encrypted! /, May be! /, And so on.

[0088] When HD information is recorded on the memory card 300, it may be automatic or manual.

[0089] In addition, the receiving terminal 200 has a function for reproducing exchange data. In this case, for example, the receiving terminal 200 has a reproduction program for moving image content that is exchange data. In this case, a moving image content playback program may be passed to the receiving terminal 200 via the memory card 300.

Similarly, if the receiving terminal 200 has a public data reproduction application, in this case, the public data reproduction application is sent to the short-distance radio unit 107, You may make it pass through 201.

[0091] In the data movement method of this example, a general-purpose memory card can be used as the memory card 300. For example, in the case of a terminal using UIM, the UIM ID may be written to the memory card 300. In the data movement method of this example, the memory card

The ID preset in 300 can be used as it is.

Further, in the data movement method of this example, since the receiving side ID can be written into the memory card 300 and read by the receiving side terminal 200, mutual authentication is possible.

In addition, according to the data movement method of this example, since ID control information for controlling ID can also be written to the memory card 300, flexible access control is possible.

As described above, according to the data movement method of this example, an SD card is used between the transmitting terminal 100 which is an information sender and the receiving terminal 200 which is an information receiver. The ID card is directly exchanged using the memory card 300, etc., and the communication partner is authenticated to exchange force information.

 Therefore, in the data movement method of this example, the sending terminal 100 of the information sender establishes a session only with the receiving terminal 200 of the other party that directly exchanged the ID via the memory card 300. The user can intuitively grasp the communication partner.

 [0096] Further, according to the data movement method of this example, only the ID is passed to the other party without moving for each UIM, so that information can be exchanged safely without trouble.

 [0097] Further, in the data movement method of this example, safe and inexpensive communication can be performed using an existing device without requiring a new device.

 [0098] By the way, in this type of data movement method, it is not possible to pass all data to the accessed party.

[0099] Therefore, in the communication system of this example, it is preferable to provide a box containing information in a bundle so that the communication partner can be individually accessed so that it can be delivered to each partner. [0100] As a communication method in this case, for example, each of nine buttons such as a terminal numeric keypad is assigned as an access button to nine data boxes for each communication partner, and each communication partner is displayed on the display screen. Nine directories of are displayed side by side. Then, only the directory corresponding to the button pressed by the user can be read and the access restriction can be removed.

 Industrial applicability

[0101] The data movement method according to the present invention can prevent unintended data exchange with a simple operation when exchanging data between terminals equipped with a short-range wireless communication function. It is useful as a data movement method when exchanging data between terminals such as DVD recorders, notebook PCs, and mobile phones equipped with a short-range wireless communication function.
