Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system for exchanging information by specifying a partner using mobile communication.
[0002]
[Prior art]
The exchange of personal information such as e-mail addresses and telephone numbers between first-time people has become commonplace in recent years. It is common to transmit personal information verbally or verbally.
[0003]
However, personal identification information such as e-mail addresses and telephone numbers must be unique throughout the country. For example, personal identification information such as e-mail addresses is long and complicated to cope with the increasing trend of users. It is becoming. For this reason, even if the mail address is spoken verbally to the other party, it may be longer or more complex than it can be stored and transmitted in a short time on the spot.
[0004]
In addition, some mobile information terminals, such as mobile phones, have multiple characters assigned to one numeric key, so input processing of kanji and English characters when entering the recipient's email address and name There is something complicated. In this case, input mistakes are likely to occur, and the input processing effort is large.
[0005]
Even when business cards are exchanged, personal information must be finally input to the portable information terminal, so that the processing is complicated and the processing effort remains the same.
[0006]
For this reason, there is an electronic business card exchange system in which personal information devices are directly faced to exchange personal information by infrared connection, or exchange personal information with each other using short-range wireless communication.
[0007]
In addition, a service is also provided in which personal information is exchanged by a user through a mobile information terminal that can be connected to a communication network such as the Internet through identification information assigned in advance.
[0008]
In addition, as in “Business card management system and business card suitable for the management system (Japanese Patent Laid-Open No. 06-223086)”, business card data is stored in a database center, and data to be disclosed by self-identification codes is classified into classes. There is a system to output.
[0009]
Furthermore, there is an information communication method using an arbitrary variable identification number, such as “Moving object compatible exchange system (Japanese Patent Laid-Open No. 2000-224638)”.
[0010]
[Problems to be solved by the invention]
However, with regard to business card exchange that is performed by infrared connection with the devices of portable information terminals facing each other directly, it is not possible to exchange information because the diffusion rate of the devices themselves is low and there are many protocols that are not compatible with each model. Many.
[0011]
In addition, for a business card exchange system using short-range wireless communication, the terminal needs to be equipped with a short-range wireless communication function, and short-range wireless communication is possible up to a range of 100 meters. Therefore, it is necessary to set an identification ID and authentication information for avoiding interference and specifying the other party. Further, since this identification ID or the like is not given by a third party but can be arbitrarily set by the user, it is not possible to completely prevent unauthorized information acquisition by so-called “spoofing”. Furthermore, since communication terminals directly exchange information, the compatibility with a communication network such as the Internet is low.
[0012]
In addition, for services that exchange personal information via user identification information (for example, user ID) on a portable information terminal that can be connected to a communication network such as the Internet, the user identification information is assigned in the order of application. Therefore, the user ID becomes longer as the number of users increases. Therefore, the problem that the burden of inputting a long user ID is large cannot be solved.
[0013]
In addition, even in the “business card management system and business card suitable for the management system (Japanese Patent Laid-Open No. 06-223086)”, the user identification number is a fixed unique number, and the problem of input burden cannot be solved. Business card data needs to be registered in the database center, resulting in a burden of data maintenance.
[0014]
In addition, in the “mobile switching system (Japanese Patent Laid-Open No. 2000-224638)”, the user can arbitrarily determine the identification number, but the identification number must be unique, and the identification information once determined is registered. It cannot be changed, and redundancy of identification information due to an increase in users cannot be eliminated.
[0015]

In the first terminal, the communication unit transmits the provision information and the first terminal identification information to the server device, and receives a first code corresponding to the first terminal identification information from the server device, and a display. The server displays a received request including a process of displaying the received first code, an input unit of a process of inputting the second code, and a communication unit including the first terminal identification information and the input second code. Processing to transmit to the device. In the second terminal, when the communication unit transmits the second terminal identification information to the server device and receives the second code corresponding to the second terminal identification information from the server device, the display unit receives the received second code. A process for displaying two codes, a process for the input unit to input the first code, and a process for the communication unit to transmit a provision request including the second terminal identification information and the input first code to the server device. The communication unit receives the access information from the server device, transmits a provision information acquisition request using the received access information to the server device, and receives the provision information. The server device includes a processing unit that acquires position information of the first terminal and the second terminal, and the code payout processing unit uses the position information of the first terminal or the second terminal as the first code and the second code. Based on the above, a code with a limited effective range is generated.
[0017]
The present invention operates as follows. When exchanging information between the terminal A and the terminal B, the terminal A sets information to be exchanged (information a) and requests the information exchange management apparatus to issue mCODE. Upon receiving the mCODE payout request, the information exchange management device adjusts the number of digits of the mCODE to be generated according to the number of mCODEs assigned at that time, generates a unique mCODE with as few digits as possible, and generates mCODE. Is associated with the information a set by terminal A, and mCODE is transmitted to terminal A for display. After that, the information exchange management device confirms that the mCODE of the terminal A is input from the terminal B which is the exchange partner and that the mCODE of the terminal B is input from the terminal A, and the terminal A The set information a is transmitted. Similarly, a unique mCODE is paid out to the terminal B, and after confirming that the mCODE is input to each other, the information b is transmitted to the terminal A.
[0018]
Further, when information is distributed from the terminal A to one or a plurality of terminals, the terminal A sets information to be distributed (information a) and requests the information exchange management apparatus to issue mCODE. Upon receiving the mCODE payout request, the information exchange management device adjusts the number of mCODE digits to be generated according to the number of mCODEs assigned at that time, and a unique mCODE (1 to 4 digits) with as short a digit as possible. The mCODE is stored in association with the information a set by the terminal A, and the mCODE is transmitted to the terminal A for display. The information exchange management device confirms that the mCODE of the terminal A is input from the terminal that is the delivery destination, and transmits the information a set by the terminal A to the delivery destination terminal.
[0019]
As a result, even if the information that you want to exchange / deliver cannot be input easily, you can easily exchange information between terminals or send information to multiple terminals by entering only 1 to 4 digits (mCODE). Information distribution can be performed.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0021]
[Configuration Example of System According to the Present Invention]
FIG. 1 shows a configuration example of a system for realizing the present invention. The information exchange management device 10 according to the present invention is connected to a mobile communication terminal 20A and a terminal 20B via a mobile communication network 30 and a mobile communication gateway 40. The terminal 20 is, for example, a mobile communication terminal (mobile phone) having a communication function based on the http protocol, and a numerical value is input to the screen display unit that can display information from the information exchange management device 10 and the information exchange management device 10. Provide possible input.
[0022]
The information exchange management device 10 connects to the subscriber information management server 50 to acquire a unique number such as a telephone number and an IP address of the terminal 20, and connects to the position information server 60 to acquire the position information of the terminal 20. Further, personal information arbitrarily registered by the user of the terminal 20 is acquired from the personal information management server 70 via the mobile communication gateway 40.
[0023]
The connection between the information exchange management device 10 and the mobile communication gateway 40 or the subscriber information management server 50 and the location information server 60 can be performed by any communication method, for example, a dedicated line, as long as necessary information of the terminal 20 can be acquired. Internet, wireless communication, or the like may be used. In addition, the mobile communication gateway 40, the subscriber information management server 50, and the location information server 60 may be individually configured as a plurality of servers, or may be configured as one server.
[0024]
In this embodiment, an information exchange partner identification code (hereinafter referred to as mCODE), which is a variable number of digits (about 1 to 4 digits) that can be easily input, is used as information for the terminal 20 to identify an information exchange partner. Use. In order to make this mCODE a short digit number, the mCODE itself has a certain lifetime, and the processing method for allowing the same mCODE (number) that has expired to be reused, and the location information server 60 grasp The mCODE is generated by combining the processing methods for using the same mCODE by managing the mCODE for each predetermined regional block by using the location information of the terminal 20 that is operating.
[0025]
Further, in order to make the mCODE input operation simpler, the mCODE is generated by increasing / decreasing the number of digits of mCODE according to the number of effective mCODEs being paid out.
[0026]
In mobile communication, when communicating between terminals 20, radio waves that can be overlapped are used, so the terminals are close to each other in the vicinity of the boundary line of the transmission / reception range of the base station. Each terminal 20 may transmit and receive with a different base station. For this reason, it may be recognized that terminals that are information exchange partners are located in different regional blocks. FIG. 2 is a diagram illustrating the relationship between the area blocks and the radio wave coverage of the base station. The small dotted circles indicate the radio wave coverage of each base station, and the solid large circles and hexagons indicate the area blocks. The base station included in the regional block may include not only a single carrier but also various carriers such as a PHS and a fixed telephone network. In other words, the area block can be managed by integrating the call area, base station ID, latitude / longitude, and a plurality of carriers into a large range of virtual area blocks and integrating various position information forms.
[0027]
Thus, even if the radio wave coverages of a plurality of base stations are combined into a large regional block, there is always a place where radio waves overlap in the vicinity of the boundary line, and it is uncertain which regional block the terminal 20 belongs to It becomes. In this way, when a unique mCODE is paid out for each regional block, the same mCODE as the mCODE paid out to the exchange partner is also given to another terminal in an adjacent regional block near this boundary line. There is a risk of mistaking the other terminal.
[0028]
Therefore, the size of the regional block is set to a size that is sufficient to prevent it from passing through the block within the mCODE lifetime even when moving on the Shinkansen or the like, and the radio wave from the regional block where the terminal 20 having the same mCODE is located. Is large enough not to be received. Furthermore, by setting the m key that is the source of mCODE and the information (adjacent area) of the adjacent area block for each area block so that a unique mCODE can be generated in the area block and its adjacent area block, An mCODE that can exchange information without misidentifying a partner even when receiving radio waves from adjacent regional blocks is generated.
[0029]
[Configuration example of information exchange management device]
The information exchange management device (mCODE server) 10 includes a system control unit 110, an http server unit 120, a location information conversion unit 130, a location information correspondence data 140, a code payout processing unit 150, an area block information 160, an information exchange processing unit 170, A code information database 180 is provided.
[0030]
The system control unit 110 controls each unit of the information exchange management device 10 and accesses the subscriber information management server 50 to convert the IP address of the terminal 20 received from the http server unit 120 into a telephone number.
[0031]
The http server unit 120 communicates with the terminal 20 via the mobile communication gateway 40 by a predetermined communication protocol such as the http protocol.
[0032]
The location information conversion unit 130 converts the telephone number of the terminal 20 into location information by the location information server 60, and specifies area block information where the terminal 20 is located from the location information based on the location information correspondence data 140.
[0033]
FIG. 3 shows an example of regional block arrangement in the present embodiment, and FIG. 4 shows a configuration example of position information correspondence data.
[0034]
In the arrangement of area blocks in FIG. 3, hexagons indicate area blocks, “a, i, u,...” Shown within the hexagons indicate area block IDs, and “1, 2, 3,. M key to be played.
[0035]
The regional block is obtained by dividing location information in advance and includes one or more ranges in which the terminal 20 can transmit and receive with the base station. Here, the number of digits of mCODE assigned to the terminal 20 in the region is A hexagonal (hex) array with a small overlap area and a small number of adjacent regional blocks is used so as to be as small as possible.
[0036]
The m key is an integer value greater than or equal to 0 from 0 to the maximum number of adjacent areas (in this case, 6) for generating mCODE that is unique in the area block and the adjacent area block. The area block ID and the m key are fixed values and are set in advance.
[0037]
The location information conversion unit 130 acquires the location information of the terminal 20 from the location information server 60 based on the telephone number of the terminal 20 acquired from the system control unit 110, and the location information corresponding data 140 in FIG. Specify the block ID. For example, if the location information of the terminal 20A is “Nakahara-ku, Kawasaki City”, it can be seen that the area block ID of the terminal 20A is the area shown in FIG.
[0038]
The code payout processing unit 150 includes a code generation unit 151 and a code digit adjustment unit 152.
[0039]
The code generation unit 151 generates mCODE that is unique in the regional block and the adjacent regional block and has a certain lifetime. In addition, using the area block information 160 of the terminal 20, an mCODE that is unique within a preset area is generated.
[0040]
FIG. 5 shows a configuration example of the regional block information. The area block information 160 includes an area block ID, m key, adjacent area, and aCODE number.
[0041]
The regional block ID is identification information fixed to the regional block. The m key is an integer unique to the area block and the adjacent area block used for generating mCODE. The adjacent area is information for specifying an area block adjacent to the area block. The aCODE number is the number of aCODEs currently paid out in the regional block. aCODE is an integer of 0 or more that is paid out for each regional block that is a source of mCODE generation. The number of digits of mCODE is adjusted according to the number of aCODEs paid out.
[0042]
The following mCODE generation processing is performed for each regional block.
1) Generate aCODE as the original code. aCODE is an integer of 0 or more. The aCODE may be serially incremented, but may be designated by a random number in consideration of security. Set life to aCODE. The service life is set to the specified service life from the time of withdrawal. The aCODE can be discarded and reused if the payout time + the time when the lifetime has elapsed.
2) Multiply aCODE by the value of the maximum number of adjacent areas + 1 in the area block array (in this case, 7 and fixed according to the maximum number of adjacent areas).
3) A value obtained by adding the m key to the calculation result of 2) is set as mCODE of the area block.
[0043]
FIG. 6 shows an example of mCODE generated in each regional block. For example, assume that aCODE “0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10” is generated. On the basis of the area block information shown in FIG. 5, in area: A, m key: 0, so the generated mCODE is “0, 7, 14, 21, 28, 35, 42, 49, 56, 63”. It becomes. In the area: i, the m key is 1, so the generated mCODE is “1, 8, 15, 22, 29, 36, 43, 50, 57, 64, 71”. As described above, by using the aCODE and the m key, a unique mCODE including the area block and the adjacent area block can be generated for each area block.
[0044]
FIG. 7 shows an example of mCODE paid out to the regional block and the terminal. In FIG. 7, a square indicates a terminal from which mCODE has been paid out, “A: 17” is a terminal 20A in the region: D, mCODE: 17 is “B: 19” is a terminal 20B in the region: Indicates that mCODE: 19 has been paid out. When the terminal A and the terminal B exchange information, since the mCODE is unique in the region “U, Se, Su, Nu, O, A”, which is the adjacent region of D, the same thing is paid out. Instead, the terminal 20A and the terminal 20B can identify each other.
[0045]
Here, since the m key is 3 for the area: sa and the area: no, the terminal C and the terminal D to which the same mCODE: 17 as that of the terminal A is paid out can exist simultaneously in these areas. However, since there is a sufficient distance between the area: D and the area: Sa or No, it is not possible for the terminal A to mistake the terminals C and D for the terminal B. The line shown in FIG. 7 that connects the area: D and the area: S with an arrow and the line that connects the area: D and the area: K with an arrow means the shortest distance between the respective area blocks. Represents a distance at which radio waves cannot be received.
[0046]
The code digit adjusting unit 152 increases or decreases the number of mCODE digits according to the number of mCODEs paid out to the terminal 20. For example, when the number of aCODEs in the regional block information 160 exceeds 10 n + 1, the code digit adjustment unit 152 expands the table of the code information database 180 to be usable up to 10 times including unused records. . Further, when the value is less than 10 to the nth power, the table of the code information database 180 is reduced to 1/10. As a result, the number of digits of aCODE, and hence the number of digits of mCODE, can be dynamically increased / decreased according to the number of simultaneous users to generate an mCODE that makes the input operation as simple as possible.
[0047]
The information exchange management unit 170 registers a record in the code information database 180 based on the mCODE paid out by the code payout processing unit 150, and manages the mCODE of the partner terminal 20 to exchange information, information to be exchanged, and the like. The code information database 180 is created for each regional block, but may be configured as one database.
[0048]
FIG. 8 shows a configuration example of the code information database. The code information database 180 has fields of aCODE, mCODE, telephone number, payout time, life, state, self-information link, partner area, partner mCODE, partner information link, and sender MSN (telephone number).
[0049]
aCODE indicates the aCODE that is the basis of the mCODE that has been paid out. The telephone number is the telephone number of the terminal 20 that is the mCODE withdrawal request source. The payout time is the total time when the mCODE is paid out in seconds. The lifetime is the mCODE effective period in seconds. The status indicates the processing status of this record, and statuses such as unused, waiting for input of the partner mCODE, and unidirectional are set.
[0050]
In the self-information link, information transmitted from the terminal 20 of the mCODE payout request source to the partner or link information to the information is set. Information to be set includes a telephone number, an e-mail address, a URL from which the personal information is acquired, and is arbitrary information.
[0051]
The counterpart mCODE is the mCODE paid out to the counterpart terminal, and is set when the counterpart terminal inputs the mCODE of this record.
[0052]
The partner area is the area block ID of the partner terminal, and is set when the partner's mCODE can be found in the adjacent area block.
[0053]
The partner information link is the partner information or a link to that information, and is set when authentication is established. It is information arbitrarily set by the other party.
[0054]
When the mCODE of the terminal 20A is generated, the information exchange management unit 170 adds a record related to the mCODE to the table of the code information database 180 of the regional block, and predetermined information (phone number, payout time, life, state, Register self-information links). Thereafter, when the mCODE of this record is set in the partner terminal 20B for information exchange, the mCODE and partner information link of the partner terminal 20B are set, and these pieces of information are returned to the terminal 20A.
[0055]
In the code information database 180 shown in FIG. 8, when the terminal 20A is mCODE: 3, if there is an mCODE payout request from the terminal 20A, mCODE = 3 is generated, and a record related to the mCODE is generated in the code information database 180. ACODE = 0, which is the source of mCODE, telephone number = 09012345678 of the withdrawal request source terminal 20A obtained from the subscriber information management server 50, withdrawal time = 300,000, lifetime = 600, self-information link set in the terminal 20A = Http: // aa / is registered. Thereafter, mCODE: 3 is input from the information exchange partner terminal 20B, and as authentication progresses, this record includes the partner area = D, partner mCODE = 10, partner information link = http: // bb / Is registered.
[0056]
When the mCODE: 10 of the terminal 20B is input to the terminal 20A, authentication is performed using the partner area and the partner mCODE of the record of the terminal 20B, and “http: // bb /” set in the self-information link is used as the terminal To 20A. Similarly, mCODE = 3 of the terminal 20A, self-information link http: // aa / is registered in the record of the terminal 20B and transmitted to the terminal 20B.
[0057]
Thus, information exchange between the terminals 20 is performed by returning the link information of the other party set in the records of the terminals to the terminals 20A and 20B.
[0058]
By the way, in mobile communication, there is a phenomenon called “crossover” (called “handover”) in which a terminal B communicating with a terminal A moves from a calling area of one base station to a calling area of another base station. Generally occurs. In the case of handover within the same regional block, the regional block ID of the terminal 20 does not change and there is no problem. However, as shown in FIG. 9, in the case of handover across other regional blocks, position information is searched. There is a need. When such a handover to another regional block occurs, the following measures are taken.
[0059]
First, in the case of exchanging information by exchanging mCODEs, the mCODE server 10 subscribes the telephone number of the requesting terminal 20 when the mCODE is input from the terminal 20 or when confirmation is requested. Obtained from the user information management server 50, based on the area block information 160, the code information database 180 of the area block where the terminal 20 currently exists and its adjacent area block are searched by telephone number, and information is found using the found record. Exchange.
[0060]
When information is distributed by paying out only one of the mCODEs, the terminal that obtains the information does not pay out the mCODE, and no record is created in the code information database 180. For this reason, when the terminal 20B crosses the area block when the terminal 20B crosses the area block further away from the adjacent area block of the terminal 20A on the information transmission side (as shown in FIG. 9), the area: There is a possibility that information that should have been received from the terminal 20A: 17 will be received from the terminal C: 17 in the region. Such a situation is dealt with by setting the size of the regional block so that the radio wave cannot be passed.
[0061]
The information exchange / distribution processing in the present embodiment will be described in detail below.
[0062]
[Example of processing (1): First when paying out mCODE to both terminals]
FIG. 10 shows an example of a normal sequence when mCODE is first paid out to both terminals, and FIG. 11 shows an example of a display screen of the terminal in that case. In the following description, it is assumed that A or B in terminal A or terminal B indicates a telephone number that identifies each terminal.
[0063]
Process (1): Terminal A transmits its own information “http: // ab /” to the mCODE server 10 and makes an mCODE request. In terminal A, the mCODE payout request screen shown in FIG. 11A is displayed, self-information is entered in the field of information to be sent, “payout” is selected (or pressed), and the mCODE request is sent.
[0064]
The mCODE server 10 acquires the position of the terminal A from the position information server 60, converts it to the corresponding area block ID, acquires that it is area: D, and randomly selects the aCODE: on the code information database 180 of that area. If the state is unused or the payout time + lifetime is older than the current time, it is multiplied by 7 which is the maximum number of adjacent areas + 1, and m key: 3 is added to generate mCODE: 17, A record of terminal A is added to the code information database 180, and a self-information link, a telephone number obtained from the subscriber information management server 50, a payout time, etc. are set. Also, the generated mCODE: 17 is paid out to the terminal A.
[0065]
Process (2): In the same way, terminal B transmits self-information “http: // cd /” to mCODE server 10 and inquires about mCODE, and mCODE: 19 is issued. FIG. 11B shows an mCODE payout request screen displayed on terminal B.
[0066]
Terminals A and B see mCODE payout result display shown in FIGS. 11 (C) and 11 (D) and their mCODE displayed on the partner mCODE input screen and communicate mCODE to each other verbally.
[0067]
Process (3): When the terminal B inputs the mCODE: 17 of the terminal A from the input screen shown in FIG. 11 (D), the mCODE server 10 that has received it inputs the position information of the terminal B from the position information acquired from the position information server 60. When the current regional block is “region:”, the code information database 180 of the adjacent region obtained from the record of the region and the region block of the region block information 160 with the telephone number obtained from the subscriber information management server 50 is obtained. By searching, the record of the terminal B is found from the same area, and the area and the adjacent area are further searched to find that the mCODE: 17 is the terminal A in the area: d.
[0068]
Process (4): The area: D and mCODE: 17 of the discovered terminal A as the information exchange partner are set in the record of the terminal B on the area: code information database 180. The mCODE server 10 responds to the terminal B to display a standby (mCODE replacement) screen shown in FIG.
[0069]
Process (5): When mCODE: 19 is input from the input screen shown in FIG. 11C at the terminal A, the mCODE server 10 receiving it inputs the current area block of the terminal A from the position acquired from the position information server 60. Is obtained from the record of the area and the area block of the area block information 160 using the telephone number obtained from the subscriber information management server 50, and the terminal is searched. A record of A is found from the same area, and the area and its neighboring areas are searched to find that mCODE: 19 is a terminal B located in the area.
[0070]
Process (6) At this time, it has been confirmed that the terminal B's record is set to the terminal A's area: D, and the partner mCODE's mCODE 17 is set to the partner mCODE. For example, the self-information link “http: // ab /” of the terminal 20A record is set as the partner information link of the record of terminal B, and the self-information link “http: // cd /” of the record of terminal B is acquired. The information is transmitted to terminal 20A. In terminal A, self-information “http: // cd /” of terminal B is displayed on the partner information display screen shown in FIG.
[0071]
Process (7): Since the mCODE of terminal A becomes unnecessary, the record is deleted from the code information database 180.
[0072]
Process (8): The terminal B confirms that the mCODE of the terminal B is input from the terminal A by pressing the confirmation button on the standby screen shown in FIG. 11E, and makes an inquiry to the mCODE server 10.
[0073]
The mCODE server 10 obtains from the location information server 60 that the regional block of the current location of the terminal B is “region:”, and stores the content (http: //) in the record of the code information database 180 of that regional block. / ab /) is sent to terminal B, the record of terminal B is deleted, and the information exchange is completed. In terminal B, self-information “http: // ab /” of terminal A is displayed on the partner information display screen shown in FIG.
[0074]
In the above example, if the region having the same mCODE as the terminal A: the terminal C: 17 of the region and the terminal D: 17 of the region: no input mCODE: 19, the region: there and region: Also: Since it is not adjacent to the area, the search is not hit and an error occurs. Further, even if the terminal B has moved to the adjacent area: Ku at the time of the processing (6), the record of the area: code information database 180 is found from the telephone number, and the adjacent area from there is searched. Therefore, the region: D cannot be searched, and the terminal C of the region: server is not mistaken for the terminal A.
[0075]
[Processing example (2): When mCODE payout and input are mutual]
FIG. 12 shows an example of a normal sequence when mCODE payout and input are mutual, and FIG. 13 shows an example of a terminal display screen in that case.
[0076]
Process (1): Terminal A transmits its own information to the mCODE server 10 and makes an mCODE request. FIG. 13A shows an mCODE payout request screen displayed on terminal A.
[0077]
The mCODE server 10 acquires the position of the terminal A from the position information server 60, converts it to the corresponding area block ID, acquires that it is area: d, and randomly stores aCODE: 2 on the code information database 180 of that area. If the state is unused or the payout time + lifetime is older than the current time, the maximum number of adjacent areas + 1 is multiplied by 7, and m key: 3 is added to generate mCODE: 17. A record of terminal A is added to the information database 180, and self-information, a telephone number obtained from the subscriber information management server 50, a payout time, etc. are set. Also, the generated mCODE: 17 is paid out to the terminal A. MCODE: 17 is displayed on the mCODE payout result display and the partner mCODE input screen shown in FIG.
[0078]
Process (2): When the terminal B inputs mCODE: 17 from the mCODE payout result display and the partner mCODE input screen (distribution mode) shown in FIG. 13C, the mCODE server 10 that has received it inputs from the location information server 60. Based on the acquired location information, the current area block of the terminal B is determined to be area: adjacent, and the telephone number obtained from the subscriber information management server 50 is acquired from the area record of the area and area block information 160 The local code information database 180 is searched, but it is determined that it does not exist because the record of the terminal B cannot be found. Further, by searching the current block of the terminal B and its adjacent area, it is found that the mCODE: 17 is the terminal A in the area: D.
[0079]
Process (3): Since the record of terminal B has not been found, it is determined that it does not yet exist, and mCODE: 19 of terminal B is generated by the same method as that of terminal A. A record for terminal B is created, and the regional block of terminal A: D and mCODE: 17 are set therein. Also, mCODE: 19 of terminal B is transmitted to terminal B. In terminal B, mCODE: 19 is displayed on the mCODE payout result display and confirmation screen shown in FIG.
[0080]
Process (4): When terminal device A inputs mCODE: 19 from the screen shown in FIG. 13B, the mCODE server 10 that has received it inputs the current area block of terminal 20A from the position acquired from position information server 60. Region: search for the code information database 180 of the adjacent region acquired from the record of the region and the region block information 160 in the region block information 160 using the telephone number obtained from the subscriber information management server 50, The record is found from the same area, and the mCODE: 19 is found to be the terminal B in the area: S by searching the area and the adjacent area.
[0081]
Process (5): At this time, since it has been confirmed that the remote area of the record of the terminal B is set to the area of the terminal A: d, and the remote mCODE is set to mCODE: 17 of the terminal A, mutual authentication is possible. As a result, the self-information link “http: // ab /” of the terminal A record is set in the partner information link of the terminal B record, and the self-information link “http: // cd /” of the record of the terminal B is acquired. Send that information to A. Terminal A displays partner information “http: // cd /” on the partner information display screen shown in FIG.
[0082]
Process (6): Since the mCODE of terminal A becomes unnecessary, the record is deleted from the code information database 180.
[0083]
Process (7): When the terminal B makes an inquiry to the mCODE server 10 from the screen shown in FIG. 13D, it is determined from the location information server 60 that the regional block of the current location of the terminal B is region: Acquired and the content (http: // ab /) is contained in the partner information link of the B record in the code information database 180 of the regional block, so it is sent to B, the B record is deleted, and the information exchange is completed To do. Terminal B displays partner information “http: // ab /” on the partner information display screen shown in FIG.
[0084]
[Processing Example (3): When unidirectionally delivering information from one terminal to multiple terminals]
When one person wants to send information to a plurality of people during a meeting, an option is given to exchange information from one terminal A as shown in FIG. 14 instead of exchanging information by mutual authentication. Information can be distributed by unilateral delivery of mCODE to terminal B and terminal C.
[0085]
However, at this time, it is easy to eavesdrop on mCODE or perform hacking by numerical brute force. As a deterrent against this, information specifying the terminal of the distribution destination, for example, a unique ID such as a telephone number, an e-mail address, an IP address, etc., is provided so that the distribution source can know who has received this mCODE. To be able to refer to. At this time, if a nickname arbitrarily assigned by the owner is assigned to the listed unique ID, the nickname is also displayed at the same time in order to improve visibility. One of the features of the information exchange processing in the present invention is that the unique ID is not shown. In this case, priority is given to simplicity by using the unique ID together.
[0086]
FIG. 15 shows an example of a normal sequence in the case of distributing information in one direction from one terminal to a plurality of terminals, and FIG. 16 shows an example of a display screen of the terminal in that case.
[0087]
Process (1): Terminal A transmits its own information to the mCODE server 10 and makes an mCODE request in the unidirectional mode. FIG. 16A shows an mCODE payout request screen displayed on terminal A.
[0088]
The mCODE server 10 acquires the position of the terminal A from the position information server 60, converts it to the corresponding area block ID, acquires that it is area: d, and randomly stores aCODE: 2 on the code information database 180 of that area. If the state is unused or the payout time + lifetime is older than the current time, the maximum number of adjacent areas is multiplied by 7 and mkey: 3 is added to generate mCODE: 17, and the code information database 180 The record of terminal A is added to the terminal, and the self information, the telephone number obtained from the subscriber information management server 50, the payout time, etc. are set. The generated mCODE: 17 is paid out to the terminal A.
[0089]
In terminal A, the mCODE payout result display shown in FIG. 16 (B) and its own mCODE displayed on the partner mCODE input screen are viewed, and mCODE is transmitted to terminal B and terminal C by oral means.
[0090]
Process (2): When the terminal B receives mCODE: 17 from the screen shown in FIG. 16C, the mCODE server 10 that has received it receives the current area block of B from the position information acquired from the position information server 60. Since the code information database 180 of the region and the adjacent region obtained from the record of the region is searched with the telephone number obtained from the subscriber information management server 50, the record of the terminal B cannot be found. Judge that it does not exist yet. Further, by searching the current block of the terminal B and its adjacent area, it is found that the mCODE: 17 is the terminal A in the area: D.
[0091]
Process (3): Since the state in the record of terminal A is “unidirectional”, the mCODE and record of terminal B are not created, and the self-information link of terminal A is transmitted to terminal B. At that time, the telephone number of the terminal B is added to the transmission destination MSN of the record of the terminal A and recorded. In terminal B, self-information “http: // ab /” of terminal A is displayed on the partner information display screen shown in FIG.
[0092]
Process (4): When the terminal C inputs mCODE: 17 from the screen shown in FIG. 16 (E), as in the case of the terminal B, the current location: C: searches for the terminal A without generating mCODE. Then, the self-information link is transmitted to the terminal C and added to the transmission partner MSN of the terminal A record. In terminal C, self-information “http: // ab /” of terminal A is displayed on the partner information display screen shown in FIG.
[0093]
Process (5): When the terminal A makes an inquiry for information transmission destination confirmation to the mCODE server 10 from the screen shown in FIG. 16B, the current regional block of the terminal A is obtained from the position information acquired from the position information server 60. If the record of the terminal A is found in the area block with the telephone number obtained from the subscriber information management server 50 and the state is unidirectional, the partner MSN in the record The array contents of (phone number) are returned to terminal A. In the terminal A, the telephone numbers which are the unique information of the distributed terminals B and C are displayed on the distribution partner confirmation screen shown in FIG.
[0094]
[Processing example (4): When mCODE is not entered, authentication is performed by setting from a list of already issued mCODEs and exchanging information]
Rather than directly inputting the numerical value of mCODE, the mCODE is disclosed in the area block and the adjacent area block only for the lifetime, and the information is exchanged by mutually authenticating only by selecting from the mCODE list. For easy understanding, a nickname arbitrarily registered by the user may be added before mCODE to be listed. This method is effective in reducing the number of operations when precise position information is obtained and there are few lists displayed in the regional block.
[0095]
FIG. 17 shows an example of a display screen in processing when exchanging registered real names in advance.
[0096]
In the terminal 20A, the nickname is registered in advance on the screen shown in FIG. 17A, the real name is set on the screen shown in FIG. 17B, and transmitted to the mCODE server 10. The registered nickname and the previous URL where the real name is recorded are returned from the mCODE server 10, the screen shown in FIG. 17C is displayed, and the URL is stored in the bookmark in the terminal 20.
[0097]
When exchanging information, instead of inputting the other party's mCODE, selection is made from the list of partner nicknames (and mCODE) on the screen shown in FIG. As shown in FIG. 17E, “naka111” is selected on the screen.
[0098]
When the mCODE server 10 confirms that “hiroz342” is set in the record of the terminal 20B of the code information database 180 when the exchange partner terminal 20B selects the nickname “hiroz342”, the nickname “naka111” is transmitted to the terminal 20A. To do.
[0099]
The terminal 20A displays the screen shown in FIG. 17F until the partner terminal 20B inputs the nickname “hiroz342”. When “hiroz342” is entered and authentication is completed, the URL generated with “naka111” is accessed, the registered real name “Iishita Gen” is obtained, and the obtained real name is displayed on the screen shown in FIG. indicate.
[0100]
18 to 20 show processing flows of the system according to the present invention. FIG. 18 is a diagram showing a processing flow of the mCODE server when receiving an mCODE payout request.
[0101]
When receiving the mCODE payout request, the mCODE server 10 acquires the position information of the terminal 20 from the position information server 60 (Step S1), converts the acquired position information into a regional block (Step S2), and corresponds to the regional block. The code information database 180 to be opened is opened (step S3). The number of used aCODEs in the area block is checked (step S4). If the number of aCODEs is <10 to the nth power, the usable range of aCODE is reduced to 1/10 (step S5), and the number of aCODEs is ≧ 10. If the power is n + 1, the usable range of the aCODE is expanded 10 times (step S6), and if neither is selected, neither reduction nor expansion is performed (default). Next, aCODE is generated with a random number within a usable range of 0 (step S7). It is checked whether or not the aCODE is within the payout time + lifetime (step S8). If it already exists, the aCODE is one by one (step S9), and the aCODE is the payout time. It is checked whether it is within the lifetime (step S10). If the aCODE is not already within the payout time + life, or if the aCODE is not within the payout time + life (life is expired), then aCODE x (maximum number of adjacent areas) +1) + m block of region block is set to mCODE (step S11), and a record in which the generated mCODE and the payout time are set is created or overwritten in the code information database 180 (step S12).
[0102]
FIG. 19 is a diagram showing a processing flow of the mCODE server when receiving mCODE input.
[0103]
When receiving the mCODE input, the mCODE server 10 acquires the location information of the input source terminal 20 from the location information server 60 (step S20), converts the location information into a regional block (step S21), and the input source terminal phone. The number is acquired from the subscriber information management server 50 (step S22).
[0104]
It is checked whether there is a record having the telephone number of the input source in the code information database 180 in the current regional block or its adjacent area (step S23). It is checked whether the mCODE input in the area of the record or in the adjacent area exists (step S24).
[0105]
If the input mCODE exists, if the partner mCODE and the partner area of the input source record are not empty (step S25), the content of the self-information link of the input source record is added to the partner information link of the input mCODE record. The contents are set (step S26), the contents of the self-information link of the input mCODE record are transmitted to the input source terminal 20 (step S27), and the input source record is deleted (step S28). If it is determined in step S25 that the partner mCODE and the partner area are empty, the discovered partner mCODE and the area block ID are set in the input source record (step S (29)).
[0106]
If the input mCODE does not exist in step S24, an error (error screen display etc.) is returned (step S30).
[0107]
On the other hand, if there is no record having the telephone number of the input source in the code information database 180 of the current area or the adjacent area in the process of step S23, the mCODE input to the current area or the adjacent area of the input source. If the input mCODE exists and the record state of the mCODE is unidirectional (step S32), the self-information link in the input mCODE record Is transmitted to the input source terminal 20 (step S33).
[0108]
If the mCODE record state is not unidirectional in step S32, the mCODE of the input source terminal 20 is generated (step S34) and transmitted to the input source mCODE input source terminal 20 (step S35).
[0109]
If there is no mCODE input in the current region of the input source or in the adjacent region in the process of step S31, an error (an error display screen indicating that the partner cannot be found) is returned (step S36).
[0110]
FIG. 20 is a diagram showing a processing flow of the mCODE server at the time of a confirmation inquiry.
[0111]
When receiving the confirmation inquiry, the mCODE server 10 acquires the position information of the inquiry terminal 20 from the position information server 60 (step S40), converts the position information into a regional block (step S41), and sets the telephone number of the input source terminal. Obtained from the subscriber information management server 50 (step S42).
[0112]
It is checked whether there is a record having the telephone number of the inquiry source in the code information database 180 in the current area block or its adjacent area (step S43). It is checked whether the mCODE record state is unidirectional (step S44). If the state of the mCODE record is not unidirectional, and if the content is included in the partner information link of the record (step S45), the content of the partner information link of the record of the query source mCODE is sent to the query source terminal 20. It transmits (step S46) and deletes the inquiry source record (step S47). In the process of step S45, if there is no content in the partner information link of the record and the record is not expired (step S48), a confirmation screen is transmitted again (step S49). If there is, an error (life expiration notification) is returned (step S50).
[0113]
If it is determined in step S44 that the mCODE record state is unidirectional, the contents of the self-information link in the input mCODE record are transmitted to the inquiry terminal (step S51).
[0114]
If no record having the telephone number of the inquiry source exists in the code information database 180 in the current area block or its adjacent area in the process of step S43, an error (data loss notification) is returned (step S52). ).
[0115]
In the description of the present embodiment, information arbitrarily set by the user, such as a URL and an e-mail address, is registered in the personal information management server 70, but only a configuration in which a link to information to be exchanged is held on the server side. In addition, it is possible to have the terminal 20 side. For example, by using the bookmark function provided in the terminal 20, such information is stored as a CGI parameter at the end of the URL to the mCODE server 10, or HTML including the CGI parameter is stored. It can be realized by calling it at the time of use. As a result, information can be exchanged without having any permanent personal information on the server side.
[0116]
Also, with mCODE alone, there is a possibility that information is exchanged by others when the terminal is lost or stolen. Therefore, when exchanging important information such as exchanging personal information, it is required to enter a separate password that is known only to the owner of the terminal at the time of mCODE request or at the time of input, and authentication is established only when it is correct. May be.
[0117]
In addition, it is convenient for information to be transmitted at the moment when mCODE is input to each other, but it may be dangerous for important information. For this reason, after inputting mCODE to each other, the information to be exchanged may be displayed after confirming with minimum information such as the partner's nickname on the confirmation screen. This nickname may be fixedly stored on the personal information management server 70 as a part of the personal information, but may be stored on the terminal 20 side and transmitted when an mCODE is requested.
[0118]
Examples of application of the present invention include the following.
[0119]
Example 1) Small payment at a vending machine or cash register
By attaching an mCODE input / output device to the vending machine or cash register and exchanging the mCODE of its own terminal with the mCODE of the vending machine etc. Exchange the withdrawal amount, withdrawal account, etc.) and perform settlement processing.
[0120]
Example 2) Information distribution from one device connected to a fixed network to a plurality of unspecified mobile communication terminals
Use of the system according to the present invention by installing authentication software that prevents a PC connected to a fixed network, not a mobile terminal, from creating a unique ID such as its IP address and registering it in a regional block Is possible. In this case, a unique ID on the network such as an IP address is used instead of the telephone number. As an application example of information distribution from these fixed networks to mobile communication terminals,
・ Exhibiting museum exhibitions to mobile terminals
・ Exhibit information URL distribution at exhibitions
・ Dissemination of publicly available information at movie theaters
・ Script distribution in theater
・ Lyric distribution at concert
Etc. In these examples, for convenience, it is possible to generate a special mCODE in which the lifetime of the mCODE is infinite from several hours instead of the usual several minutes. In addition, in the case of an unspecified partner, in consideration of privacy, unlike a normal unidirectional information distribution, distribution is performed without acquiring a unique ID such as a telephone number of the distribution side.
[0121]
Example 3) Information distribution by writing mCODE to the mail address itself
If mCODE is written in the mail address itself and the mCODE is exchanged when forwarding mail from another person to a nearby person, it is not necessary to input a long address for the destination. In this case, the receiving side also acquires mCODE in advance. The payout method at this time may be a Web page, an automatic response by sending mail to a certain fixed mail address, or an automatic voice response by calling the center. In order to distinguish from a normal mail address, mCODE with a symbol that cannot be a normal address such as an “@” symbol at the head is transmitted as a mail destination.
[0122]
When the mail server dedicated to mobile communication to which the present invention is applied receives a mail with the mCODE as the destination, the mobile server makes an inquiry to the mCODE server, and the telephone of the mobile terminal to which the mCODE is paid out in the source area and its neighboring areas Search for a number and send an email to the email address corresponding to the phone number.
[0123]
Example 4) Example of using mCODE as a telephone number
If mCODE is used as a telephone number when transferring a telephone to a nearby person, it is not necessary to input a long telephone number having 11 digits. The side receiving the transfer acquires mCODE in advance. The payout method at this time may be a Web page, an automatic response by sending mail to a certain fixed mail address, or an automatic voice response by calling the center. In this case, in order to distinguish from a normal telephone number, a call is made using a special number or a prefixed * or # as a destination telephone number.
[0124]
When a mobile communication telephone switch to which the present invention is applied receives an mCODE as a telephone number, it makes an inquiry to the mCODE server, and searches for the telephone number of the mobile terminal from which the mCODE is issued in the source area and its neighboring areas. Then call the phone number or forward it if the caller is already talking.
[0125]
The information exchange management device 10 that implements the present invention can be implemented as a computer-executable program. This program can be provided by being stored in an appropriate storage medium such as a portable medium memory, a semiconductor memory, or a hard disk that can be read by a computer, or can be transmitted and received via a communication interface. As a communication network connected as a communication interface, for example, a LAN, WAN, Internet, analog telephone network, digital telephone network, wireless communication network, or the like can be used.
[0126]
【The invention's effect】
As described above, according to the present invention, when information is exchanged between terminals, a code (mCODE) having a variable number of valid digits only for a certain period or a certain range is automatically issued, and this code is If authentication is completed when input from the partner, information set in advance is returned to the partner. By performing this process on both terminals, information exchange by mutual authentication can be easily performed.
[0127]
In addition, the following effects are achieved.
In the present invention, the authentication information for specifying the other party can be input with a short number of about 1 to 4 digits, so that it can be easily transmitted to the other party verbally and the input operation is facilitated.
In the present invention, since the mCODE is automatically issued every time information is exchanged, it is not necessary to register a unique ID or password in advance.
-The mCODE for exchanging information is effective only within a certain period of time and is less likely to be used illegally.
-Since information to be exchanged can be set at the terminal at the time of exchange, only the information to be transmitted can be exchanged.
-Since the information to be exchanged is exchanged on the server, there is no load on the terminal.
-Since this invention transmits and receives mCODE using a mobile communication network, it is not necessary to give a special apparatus for near field communication to a terminal.
-Since personal digital assistants are used for direct face-to-face information exchange, it becomes difficult for other people to impersonate and exchange information, improving safety.
The present invention provides a function of specifying an information exchange partner among a plurality of mobile terminals and exchanging or distributing arbitrary information. This makes it possible to easily exchange e-mail addresses and telephone numbers, distribute conference material URLs to a plurality of terminals, distribute store opening information URLs at exhibitions, and the like.
