Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses an information medium, such as a business card, on which predetermined information is recorded, and an information center, which is accessible by a communication medium, such as the Internet, and stores personal information of a specified number of members. , A personal information management method for storing, updating and providing personal information of members.

[0002]

2. Description of the Related Art Conventionally, a business card of another member obtained by exchanging business cards is simply stored in a business card holder, or information such as the name, company name, and contact information of another member recorded on the business card is stored. And a recording medium (HD) through an input means of a computer.
D, FD, etc.) and stored.

[0003] However, if the information on the other member's business card changes after the business card exchange, the fact that the change has been made must be known unless the change is notified. become. As a result, there have been many situations in which, even if you call the contact information on the business card, you will not be able to contact you due to a transfer, or you will be rude to the other party by calling the title before the change. Was. In addition, there is a problem that even if a notification of a change regarding information described on a business card is received, it takes time and effort to change information stored in a recording medium or the like.

In view of such problems, Japanese Patent Laid-Open No.
Japanese Patent No. 31363 discloses the following technology. First, a member having a first information card (for example, a business card) to which a sticker on which predetermined information including card identification information is recorded is attached to a second information card (for example, a business card) from another member or associate member. Upon receipt, the sticker is peeled off from the first information card, and the sticker is attached to the second information card. This allows the first information card and the second
A one-to-one relationship is established between the information cards. The member who has obtained the second information card transmits the information obtained by adding the information of the second information card to the information of the first information card recorded on the sticker to the center via the transmission means,
The center member information file that manages the member related information and the associate member related information is updated.

[0005] At the time of transmission from the member to the center, the member provides the member's own personal information to other members or associate members who handed the first information card in accordance with the degree of intimacy. A class value that defines the range can be determined and registered in the center member information file. Thus, when another member or associate member accesses the center member information file, the range of providing the member's own personal information to the other member or associate member can be limited.

[0006]

In the technique described in the above publication, it is necessary to attach a predetermined sticker to the first information card (business card), and when the information card (business card) is replaced, It is necessary to peel off the sticker from the first information card (business card) and attach the sticker to the second information card (business card) obtained from the other party. Also, in order to determine the range of providing personal information of the member to other members or associate members, the member determines the class value and registers it in the center member information file when transmitting from the member to the center. There must be.

[0007] In view of these problems, the present invention provides an information medium (for example, a business card) without attaching a sticker or the like.
Information in which personal information of a specific large number of members is stored simply by exchanging business cards with other members and then using a computer and peripheral devices (including communication terminals) owned by the member user. From the center storage section of the center,
It is an object of the present invention to provide a personal information management method that allows the latest personal information of another member to be extracted via a communication medium such as the Internet.

[0008]

According to a method for managing personal information according to the present invention, personal information of a specific number of members (for example, work Information and home information) via a communication medium (for example, the Internet) to a communication terminal (for example, a modem or terminal adapter connected to a personal computer) owned by the member user. Wherein the information center stores in advance the personal information of the specified number of members in the center storage unit as a personal information file for each member; and After obtaining an information medium (for example, a business card) on which a transmission code including an identification code (for example, represented in the form of a number or a barcode) is recorded, the transmission code is obtained. To the information center; and the information center transmits the other member's personal information file selected based on the other member's member identification code in the transmission code transmitted from the user. And transmitting to the user.

According to the present invention, the user can use an information medium containing a member identification code of another member (for example, a tangible object such as a business card, or a digital code containing a member identification code of another member obtained on the Internet). After that, the latest personal information on the other member can be obtained from the information center via a communication medium such as the Internet. The obtained personal information of the other members may be stored in a user storage unit (HDD or the like) connected to the communication terminal, or simply displayed on a display unit (CRT or the like) of a personal computer. Or just

In a preferred embodiment of the method of the present invention,
The information center has two or more personal information files for each member (for example,
Personal information file relating to the home), and the code for transmission of the other member is to be transmitted to the user together with the member identification code of the other member. An example in which a disclosure code for specifying a personal information file of a member is included can be given.

In this case, the personal information files of the other members may include, for example, a personal information file relating to the workplace and a personal information file relating to the home. The personal information file described above may be included. Here, the two or more personal information files relating to the work place are, for example, when one member owns two or more companies (for example, company A and company B), information about company A (for example, A personal information file containing titles, contact information, etc.) and a personal information file containing information about company B (titles, contact information, etc.).

[0012] Taking the case where the personal information file of the other member includes a personal information file relating to the place of work and a personal information file relating to the home as an example,
It has a plurality of information media (business cards) having different disclosure codes, and when exchanging business cards, taking into account the degree of personal relationship and intimacy between the other member and the user, the information media (business cards) are provided. A kind of information medium (business card) selected from among the business cards may be given to the user. Information medium (business card) passed to the user
For example, a disclosure code for permitting the disclosure of both the workplace information and the home information of the other member is recorded.

[0013] The user who has obtained the information medium (business card) from another member can use the personal information management software (communication software) programmed to carry out the method of the present invention to transmit the transmission code. (Member identification code of another member,
And the code for disclosure) are input to the computer, and then the code for transmission is transmitted to the information center together with the user's own member identification code and member PIN code, and is disclosed in the information medium (business card) obtained from another member. Code for use (for example, a code to permit disclosure of both work information and home information)
The personal information file (including office information and home information) of another member provided by the information center may be received based on the information. Thereafter, even when the personal information of another member in the storage unit for the center is changed, the user accesses the information center by accessing the latest personal information file of the other member stored in the storage unit for the user. It can be obtained by doing.

In the method of the present invention, the user sets a plurality of categories in the user storage section according to the type of business, etc., and saves and updates information of members who have exchanged business cards for each category. Can be. Further, if the user is a corporation, the employee's personal information (for example, each employee corresponds to a member in the method of the present invention) (for example,
(Department and post title) can also be shared.

In the personal information management method, even if the user's member identification code and member PIN are stolen by another person (other than a member), the other person enters the information center. It is preferable to adopt a method that can prevent unauthorized access of the server. Specifically, as an example of a preferred embodiment of the method of the present invention, a variable password is stored in each of a center storage unit of the information center and a user storage unit connected to the user communication terminal. Storing in advance, and the information center includes:
At the time of transmission to the user before transmitting the personal information of the other member to the user (for example, at the time of previous transmission), the variable secret code is automatically changed and stored in the center storage unit. Transmitting the changed variable PIN code to the user, and the user storing the changed variable PIN code transmitted from the information center in the user storage unit; and Transmitting the changed variable personal identification code stored in the user storage unit to the information center, together with the transmission code in the information medium obtained from the other member; and The changed variable PIN transmitted from the user is compared with the changed variable PIN stored in the storage unit for the center, and as a result,
Transmitting the personal information file of the other member to the user only when both match,
In addition, there may be mentioned those containing (claim 3). By using the variable password as described above, even if the user's member identification number and member password are stolen by another person, the information center is illegally accessed from a personal computer owned by the other person. The situation can be prevented.

In the method of the present invention, the information center may further include, for the user, the personal information file of the user stored in the storage unit for the center together with the personal information file of the other member. The advertisement information selected based on the personal information may be transmitted (claim 4). In this case, as the advertisement information, for example, immediately after the workplace of the user (member) is changed to a foreign-affiliated company, the URL of a company related to English education

You can communicate with. The information center staff can use the input unit 45 and the CRT 44 to perform management tasks for the information stored in the center storage unit 41 at any time.

The member's personal information stored in the storage unit for the center is divided into one or a plurality of personal information files for each member, and one or more personal information files among them can be taken out simultaneously. . Here, the "personal information file" refers to an aggregate of personal information of each member that cannot be further finely divided and taken out when taken out from the storage unit for the center. The personal information file includes, for example, a file of work information and a file of home information. Here, the work place information includes, for example, a photograph of the face of the member, a company name, a location of the company, a department, a position, a telephone number, an e-mail address, a self-introduction, and the like. The home information includes, for example, home address, telephone number, family structure, self-introduction and hobbies of each family member, mourning information, and the like. The home information file may be divided into two or more files according to the degree of secrecy. The personal information file may be one or two or more files including only the workplace information (for example, a file related to Company A and a file related to Company B). Further, the personal information file may be a single file including work information and home information. Therefore, the method of the present invention can be suitably used by a wide range of employees such as office workers, sole proprietorships, students, and housewives.

In order for a user to become a member using the method of the present invention, the user may perform an enrollment procedure according to the procedure shown in FIG. 4, for example. First, using a personal computer and a communication terminal connected to the personal computer, a user accesses a homepage of a company that provides software for managing personal information via the Internet (step 1; Abbreviated.) On this homepage, select a new member registration screen, and further, on a screen for inputting predetermined personal information, the user's own predetermined personal information (eg, name, address, telephone number, credit card number, etc.)
Is input (step 2). After the input, the provider of the personal information management software transmits the personal information management software with the member identification number, the member PIN, the variable PIN and the disclosure number attached to the user (step 3). . The user saves the transmitted personal information management software and the like in the user storage unit (HDD) of the personal computer owned by the user. The member PIN can be changed later by the user.

In the information stored in the user storage unit,
For example, the information of the membership card shown in FIG. 5 is included. The membership card book is printed in the form shown in FIG. 5 by printing with a printer connected to a personal computer. FIG.
Among them, what is printed at the top of the membership card book are numbers and bar codes representing the member identification number and the disclosure number. That is, the member identification number and the disclosure number are represented by numbers and also by bar codes. Therefore, the person who receives this business card,
A number may be input using a computer keyboard, or a barcode may be read using a barcode reader. Disclosure number (12
3456) indicates that only the workplace information of the user is provided to other members.

The membership card also includes a disclosure number for defining a different disclosure permission range for the user's personal information.
Has been described. “Disclosure number 2” described in the membership card book of FIG. 5 is a number for providing personal information (home information) including a home address and the like. If only the “disclosure number” (123456) in FIG. 5 is printed on the business card, only the workplace information will be provided. If only the “disclosure number 2” (123123) is printed on the business card, the home information will be provided. Only the “Disclosure Number” (12
3456) and “Disclosure number 2” (123123) together with “123456123123”,
It will provide both work information and home information. If neither the “disclosure number” (123456) nor the “disclosure number 2” (123123) is printed on the business card, no personal information is provided. Based on these four disclosure methods, four types of business cards can be prepared. “Personal identification number 1” described in the membership card book is a number used when the user changes his / her personal information (workplace information or home information). In addition, the member identification number and the disclosure number may be represented only by numbers, or may be represented only by bar codes. Also,
The number for disclosure is, for example, “12345” without separating the number for providing work information and the number for providing home information.
For example, six digits such as "6 (workplace information only)", "121212" (home information only), and "343434" (both workplace information and home information) may be used. The number is 6
The number is not limited to five digits, and may be five digits or less, or seven digits or more, and is arbitrary.

The user, for example, stores a business card recording a disclosure number for providing only workplace information and a business card recording a disclosure number for providing both workplace information and home information. When preparing and exchanging business cards, one of these two types of business cards may be presented according to the other party. FIG. 6 shows an example of a business card on which a number representing a member identification number and a disclosure number and a barcode are actually printed. For example, it is convenient to color-code the two business cards to distinguish them.

Next, even if the member identification number and the member PIN of the user are stolen by another person, the personal information of the other member owned by the user cannot be known by another person. For the technology, the use of variable PINs,
A description will be given together with a procedure for collectively updating information of other members owned by the user.

In order to collectively update the personal information of the other members owned by the user, the user first adds a personal identification number, a member PIN, and a variable PIN as shown in FIG. A signal requesting a batch update of information (for example, 6
(A code consisting of a digit of alphanumeric characters) is transmitted to the information center.
In the information center, after collating each of the user's member identification number, member PIN, and variable PIN, the personal information of the other members at the present time and the personal information of the user (for example, a male of 18 to 38 years old) Is transmitted to the user (for example, advertisement information of a sports car by a car sales company) selected on the basis of. Among the personal information of other members, information that has been changed recently (for example, within one month) may be separately displayed on the user's personal computer screen in the form of a list or the like as the latest changed information. It is.

At this time, the variable password is changed at random (randomly), and the changed variable password is stored in the center storage unit in the information center, transmitted to the user, and stored in the user storage unit. Let me save. When the user transmits next time, the user transmits the changed variable password together with other information (such as the member identification number of another member). The information center collates the changed variable password stored in the information center with the changed variable password transmitted from the user. If these variable passwords match, it means that the information is transmitted from the computer owned by the user to the information center. Conversely, if these variable PINs do not match, a person who has stolen the user's member identification number and member PIN from the user illegally accesses the information center using his / her own computer. Will be.

As described above, when another person steals the member identification number and the member PIN of the user, even if the other person accesses the information center, the variable PIN has already been changed by the user. , By collation at the information center,
The retrieving of information from the storage unit for the center is rejected, and information on other members cannot be obtained. Further, by employing a variable password, it is possible to prevent illegal copying of the personal information management software.

Normally, the variable password is automatically changed at every communication with the user at the information center. The variable password may be changed at random (at random) or at the time of access from the user (for example, 14:02).
(5 minutes) may be used to give some meaning, such as “1425”.

The storage unit for the center of the information center stores personal information of members and can change the personal information as needed. That is, to change the personal information of the user (member), the user himself
Activate the personal information management software, access the information center via the Internet network, and send the information to be changed (for example, department name, job title, telephone number, etc. newly assigned at the work place) What is necessary is just to change the user's own personal information in the center storage unit. In this case, by using the above-mentioned variable password, it is possible to prevent another person from altering the user's personal information without permission. In order to change the user's personal information, the user sends the information to be changed to the information center in writing, and the staff of the information center receiving the document writes the user's personal information stored in the storage unit for the center. May be changed using the input unit of the computer.

The member identification number, member PIN, disclosure number, and variable PIN can be any codes as long as they can be read by a computer. For example, it is possible to use a keyboard that can be input with a keyboard (usually a combination of about 4 to 10 numbers and alphabets).

Next, the user exchanges a business card with another member,
An example of a procedure for obtaining the personal information of another member by the method of the present invention will be described with reference to FIGS. In FIG. 8, the user (Mr. B) who is a member exchanges business cards with another member (Mr. C) to obtain a business card of Mr. (Step 11; abbreviated as “S11” in FIG. 8). In addition, on C's business card,
Mr. C's member identification number and disclosure number are printed.
Mr. B can perform the following procedure immediately based on the business card of Mr. C, or perform the following procedure based on a plurality of business cards after collecting several business cards other than Mr. C. You may.

Mr. B starts the personal information management software on the personal computer (step 12), and reads the member identification number and disclosure number recorded on Mr. C's business card using a bar code reader, or uses a keyboard. Then, the member identification number and the disclosure number recorded on the business card of Mr. C are input using the numeric keypad (step 13). Next, B
, B to the information center via the Internet
The member's own member identification number, member PIN, variable PIN, and C's member ID and disclosure number are transmitted (step 14).

The information center receives the information from Mr. B (step 15), and receives the received member ID number of Mr. B,
The member personal identification number and the variable personal identification number are collated with the member identification number, the member personal identification number, and the variable personal identification number of Mr. B stored in the center storage unit of the information center (step 16).

If all the numbers match as a result of the check, it is checked whether or not the number of transmissions from Mr. B is within 3 times / day (step 17). As a result, if the number of transmissions is less than 3 times / day, the information center changes B's variable password and B's personal information (hobby, etc.).
(Step 18). Here, if the number of transmissions exceeds 3 times / day, the information center once charges a communication fee, confirms with Mr. B, then changes the variable password and selects the advertising information ( Step 19).

Next, the information center collates the member identification number and disclosure number of Mr. C transmitted from Mr. B with the member identification number and disclosure number of Mr. C stored in the storage unit for the center. (Step 20). As a result, if these numbers match, the disclosure number of Mr. C (for example,
Mr. C's personal information (for example, a number indicating that both work information and home information are provided) (for example,
The work information file and the home information file), the variable password after the change, and the advertisement information are transmitted to Mr. B (step 21). The information center checks whether the personal information file of the other members owned by Mr. B is the latest one (step 22). If not, Mr. B determines whether or not to update to the latest data. (Step 23), and updates to the latest data (step 24).

Mr. B obtains Mr. C's personal information from the information center via the Internet network, saves it in the user storage unit, views the advertisement information, and downloads the advertisement information to the homepage of the desired advertisement providing company. Access (Step 2
5). Since Mr. B sends the changed variable PIN number when accessing the information center next time, it is possible to prevent unauthorized access from a personal computer other than the personal computer owned by Mr. B.

On the other hand, when Mr. C tries to disclose personal information including home information to Mr. B at the time of exchanging business cards, he later decides to limit his disclosure to only work information. Access to the information center, designate Mr. B based on Mr. B's business card, and specify the range of information to be provided to Mr. B (that is, C to be sent to Mr. B)
'S personal information file) can be changed. Mr. C can also stop providing personal information to Mr. B. Further, by accessing the information center, for example, Mr. C can obtain a list of members to whom Mr. C's information can be provided at the present time (that is, all members who have passed the business card so far) and the information disclosure permission range. Information can be provided from an information center.
