Description

  The present invention relates to a related information providing system, and more particularly, to a system for providing personalized information to a user without centrally managing the personal information of the user.

Until now, in the marketing world, it is believed that sales can be increased by collecting and accumulating personal information of users and providing customized product / service information for each person based on such information. Has been.
For example, when a PC software purchaser registers as a user, sex, age, occupation, e-mail address, subscription provider, Internet connection method (ADSL, FTTH, ISDN, etc.), machine used, purchase shop, personal computer history Such information is obliged to be disclosed, and based on such information, new product guide mails and DMs are sent.
Alternatively, when a user accesses a website and enters an ID and password, a web page optimized for the user is dynamically generated, and a product that matches the attribute of the user is proposed and an advertisement is displayed. Has been implemented.

Thus, it has been considered that selecting information to be transmitted based on the personal information of the user has advantages for both the seller and the user.
For example, if the new product is for advanced computer users, it is highly likely that it would be useless to send information to beginners of computers. Therefore, information will only be sent to users with relatively long personal computer history. Is efficient.
It can be said that it is welcome for the sending side to select from the beginning because it is only annoying even if guidance is sent about products that are not related to them.

From this point of view, in the following Patent Document 1, customer personal information (age, gender, etc.) is registered in the customer database in association with the customer ID, and the card reader stores the ID recorded on the customer card. There has been disclosed a system that, when read, performs matching between the customer's personal information and an advertisement information table and displays optimal advertisement information on a screen.
JP-A-11-52900

Even if you are a user, there are various economic conditions and life stages. Therefore, providing personalized product information as described above enables you to purchase products compared to sending DMs indiscriminately. It is possible to increase the probability.
It is also theoretically possible to stimulate potential user needs and drive new purchasing behavior.
Furthermore, for products with a wide range of peripheral devices and maintenance products such as personal computers and automobiles, the presence of such information is often not noticeable without the active transmission of information from the seller. It is also beneficial for

However, on the other hand, there is a strong caution on the part of users that their personal information is managed by the seller, and the number of people who refuse to subscribe to services that require the disclosure of personal information is increasing. ing. In fact, since personal information leaks and misuse cases occur one after another, such a user's attitude cannot be dismissed as mere depression.
On the other hand, it is beginning to be pointed out that the sales promotion effect is not as high as expected on the side of the seller, despite the huge cost of database construction, system maintenance and security measures (see the following Web Page).

FIG. 1 is a block diagram showing a configuration when registering personal information in the first related information providing system 10 according to the present invention.
In this case, the first related information providing system 10 includes an in-store terminal 12 as a personal information registration device, a membership card 14 possessed by the user, and a warranty card 16 of the product purchased by the user.

The in-store terminal 12 includes a display 18, an input device 20 such as a keyboard, a touch panel, and a numeric keypad, a reader / writer 22 for an RFID tag, and a personal information registration unit 24.
The personal information registration unit 24 is realized by the CPU of the in-store terminal 12 executing necessary processing according to the OS and a dedicated application program.

The membership card 14 is independent of the general information storage area 26 for storing general card information managed by the card issuer, such as a card number, user ID, expiration date, and service point. It has at least two storage areas for the RFID tag 28 that is not managed by the issuer.
A unique identification code assigned by the manufacturer is registered in the RFID tag 28 at the time of shipment.
The general information storage area 26 is preferably constituted by an IC chip memory, but may be constituted by other storage media such as a magnetic stripe or a two-dimensional barcode.

  The product warranty card 16 includes an RFID tag 30 in which a product code (JAN code) and the like are stored in addition to a print area in which warranty contents and warranty conditions are printed.

Next, according to the flowchart of FIG. 2, a processing procedure when the user registers purchased product information as a kind of personal information in the store will be described.
For example, when a user purchases a personal computer at a personal computer shop, the store staff takes out the warranty card 16 from the box, and writes information such as the store code and purchase date on the RFID tag 30 in an uncorrectable state by the reader / writer in the cash register ( S10).
Here, the user brings the membership card 14 and the warranty card 16 of the personal computer chain, which have been issued in advance, to the installation location of the terminal 12 in the store, and places both RFID tags 28 and 30 to the reader / writer 22.

As a result, the warranty card 16 is dedicated to the user and abuse by a third party is eliminated.
Next, the personal information registration unit 24 displays a message prompting the user to input the password of the user (S16).
When the user who has received this input his / her password via the input device 20, the personal information registration unit 24 generates encrypted product information, which is sent to the RFID tag 28 of the member card 14 via the reader / writer 22. Write (S22).
At this time, the personal information registration unit 24 generates encrypted product information in the following manner.
(1) A cryptographic function is generated by applying a hash function to a character string obtained by synthesizing the identification code stored in the RFID tag 28 of the membership card 14 and the password input by the user (S18).
(2) The product code read from the RFID tag 30 of the warranty card 16 is encrypted using the encryption password as a key (S20).

FIG. 3 is a block diagram showing a configuration when providing related information in the first related information providing system 10.
In this case, the first related information providing system 10 includes an in-store terminal 12 as a related information providing device and a member card 14 possessed by the user.
The in-store terminal 12 includes a display 18, an input device 20, a reader / writer 22 for an RFID tag, and a related information providing unit 32.
The related information providing unit 32 is realized by the CPU of the in-store terminal 12 executing necessary processes according to the OS and a dedicated application program.
Further, the related information providing unit 32 is connected to the in-store database 34 via a network such as a LAN.

Next, a processing procedure for presenting information related to personal information to the user will be described with reference to the flowchart of FIG.
First, a user who visits a computer shop approaches the in-store terminal 12 and puts the membership card 14 on the reader / writer 22.
Receiving this, the related information providing unit 32 reads the identification code from the RFID tag 28 of the member card 14 (S30), and displays a message prompting the input of the password on the display 18 (S32).
When the user who has received this enters his / her password via the input device 20, the related information providing unit 32 combines the identification code read from the RFID tag 28 of the membership card 14 with the password entered by the user. The encrypted password is reproduced by applying a hash function to the column (S34), and using this as a key, the encrypted product information stored in the RFID tag 28 of the member card 14 is decrypted (S36), and the product code is obtained.

Next, the related information providing unit 32 extracts attribute information such as the product name associated with the product code from the in-store database 34 (S38), and the product information registered in the member card 14 as shown in FIG. The list screen 36 is displayed on the display 18 (S40).
In the figure, an example in which two pieces of product information are registered in the member card 14 is shown.

On the other hand, when the user touches the “display related information” button 38 related to “Company A notebook PC AXB-306X” to request the display of related information (S42), the related information providing unit 32 displays the relevant PC. The store database 34 is searched using the product code as a key, and information associated with the product code is extracted (S44).
Next, the related information providing unit 32 displays a list of search results on the display 18 (S46).
FIG. 6 shows an example, and the stock status and sales floor information are listed together with the related product name (including manufacturer name and model number) of “Company A Notebook PC AXB-306X”.
When the user touches and selects a “detail” button 40 related to a specific related product, the related information providing unit 32 extracts detailed information (spec table, catchphrase, etc.) of the related product from the in-store database 34 and displays it. 18 is displayed.
Although illustration is omitted, when related information other than related product information such as information on the succeeding model and program bug information exists in the in-store database 34 for the “Company A notebook PC AXB-306X”, the related information providing unit 32 Is extracted and displayed on the display 18 together with the related product list.

According to the first related information providing system 10, the user can efficiently obtain only the information related to the product purchased by the user simply by placing the user's membership card 14 over the in-store terminal 12.
Moreover, since the in-store terminal 12 extracts related information on the spot based on the purchased product information registered in the membership card 14, the purchased product information, which is the user's personal information, is stored on the computer shop or chain side. Will not accumulate.
In addition, a large-scale information system for centrally managing the user's personal information is unnecessary, and it is only necessary to install an in-store terminal 12 having a simple configuration and prepare an interface for connection to an existing system. Therefore, the initial cost and running cost can be significantly reduced.
In addition, since the product information recorded on the membership card 14 is encrypted, even if it is read by a reader / writer elsewhere, it cannot be decrypted unless a password is manually entered, ensuring high security. ing.

  The in-store terminal 12 can be configured as an information processing terminal similar to a personal computer, but it is necessary to use an existing point management terminal or multimedia terminal, such as a reader / writer 22 for RFID tags, or a dedicated application program. It can also be realized by adding.

FIG. 7 is a block diagram showing a configuration at the time of personal information registration in the second related information providing system 50 according to the present invention.
In this case, the second related information providing system 50 includes a personal computer 52 as a personal information registration device installed in the home, a member card 14 possessed by the user, a warranty card 16 for the product purchased by the user, and the Internet 54. And an intermediary server 56 connected through the network.

The personal computer 52 includes a display 58, an input device 60 such as a keyboard and a mouse, and an RFID tag reader / writer 62 connected to a USB port. In addition, a dedicated application program is set up in the hard disk, and the personal information registration unit having the same functions as described above is executed by the CPU of the personal computer 52 according to the OS and the application program. 64 is realized.
For this purpose, the user accesses the website of the personal computer chain in advance, downloads necessary application programs, and sets up the personal computer 52 in advance.
In this application program, the URL of the mediation server 56 is set in advance.

Next, a processing procedure when the user registers product information at home will be described with reference to the flowchart of FIG.
In this case, the user puts the member card 14 and the RFID tags 28 and 30 of the warranty card 16 on the reader / writer 62 of the personal computer 52. In the RFID tag 30 of the warranty card 16, the store code and purchase date are written in advance in an uncorrectable state by the staff of the computer shop.

On the other hand, the personal information registration unit 64 of the personal computer 52 first reads the identification code from the RFID tag 28 of the member card 14 (S50), and writes it into the RFID tag 30 of the warranty card 16 in a write-protected state (S52). As a result, the warranty card 16 is dedicated to the user and abuse by a third party is eliminated.
Next, the personal information registration unit 64 displays a message prompting the user to input the password on the display 58 (S54).
In response to this, when the user inputs his / her password via the input device 60, the personal information registration unit 64 generates encrypted product information.
Also in this case, the personal information registration unit 64 generates encrypted product information in the following manner as described above.
First, an encryption password is generated by applying a hash function to a character string obtained by synthesizing the identification code stored in the RFID tag 28 of the membership card 14 and the password input by the user (S56).
Using this encryption password as a key, the product code stored in the RFID tag 30 of the warranty card 16 and the URL of the mediation server 56 are encrypted (S58).
However, not all of the encrypted product information generated here is written to the RFID tag 28 of the member card 14, and only a part thereof is stored in the RFID tag 28 of the member card 14 together with the URL of the mediation server 56. (S60).

Next, the personal information registration unit 64 accesses the mediation server 56 via the Internet 54 and requests registration of an identification code and a password (S62).
When the registration process by the mediation server 56 is completed (S64), the remaining part of the encrypted product information (the encryption generated by the personal information registration unit 64) is sent from the personal information registration unit 64 of the personal computer 52 to the mediation server 56. In the merchandise information, all remaining portions except for the portion written in the RFID tag 28 of the member card 14 are transmitted (S66). This communication itself is also encrypted by SSL (Secure Socket Layer) or the like.
Receiving this, the mediation server 56 registers the remainder of the transmitted product information in a predetermined database in association with the identification code (S68).

FIG. 9 is a block diagram showing a configuration at the time of product information provision in the second related information provision system 50.
In this case, the second related information providing system 50 includes an in-store terminal 12 as a related information providing device, a member card 14 possessed by the user, an intermediary server 56, and a plurality of Web servers 66.
The in-store terminal 12 includes a display 18, an input device 20, a reader / writer 22 for an RFID tag, and a related information providing unit 32.
The related information providing unit 32 is connected to the mediation server 56 via the Internet 54.

Next, a processing procedure when the user browses related information in the store will be described with reference to the flowcharts of FIGS. 10 and 11.
First, a user who visits a computer shop approaches the in-store terminal 12 and puts the membership card 14 on the reader / writer 22.
On the other hand, the related information providing unit 32 reads the identification code from the RFID tag 28 of the member card 14 (S70), and displays a message for prompting the input of the password on the display 18 (S72).
When the user who receives this inputs his / her password via the input device 20, the related information providing unit 32 combines the identification code read from the RFID tag 28 of the membership card 14 with the password input by the user. The hash password is applied to reproduce the encrypted password (S74), and the URL of the mediation server 56 stored in the RFID tag 28 of the membership card 14 is decrypted using this as a key (S76).

Next, the related information providing unit 32 accesses the mediation server 56 based on the URL (S78), the identification code stored in the RFID tag 28, the password input by the user, a part of the encrypted product information, and the store code. Is transmitted through a communication path encrypted by SSL or the like (S80).
Receiving this, the mediation server 56 reproduces the encrypted password by applying a hash function to the character string obtained by synthesizing the identification code and the password (S82).
Next, a part of the transmitted encrypted product information is combined with the remaining part registered in the database, and the product code is decrypted by applying the encrypted password as a key to this (S84).

Next, the mediation server 56 accesses a predetermined Web server 66 on the Internet 54 and requests a search process for information associated with the product code (S86).
For this reason, the correspondence relationship between the product code and the URL indicating the location of the related information is registered in the mediation server 56 in advance.
For example, the URL of the Web server 66 operated by the manufacturer or peripheral device manufacturer is registered as a search processing request destination.
In addition, the URL of the Web server 66 operated by the personal computer shop and the URL of the Web server 66 operated by the chain headquarters can be registered as a search processing request destination.

When the search result is transmitted from each Web server 66, the mediation server 56 generates a list of search results and transmits it to the in-store terminal 12 (S88).
As a result, a list of related products is displayed on the display 18 of the in-store terminal 12 (S90).
On the other hand, when the user touches a specific related product listed in the list and requests display of detailed information (S92), the request is transferred to the Web server 66 by the mediation server 56 (S94).
Further, when the detailed information is transmitted from the Web server 66, it is transferred to the in-store terminal 12 via the mediation server 56 (S96) and displayed on the display 18 (S98).

In the case of the second related information providing system 50, only part of the product information is exchanged on the Internet 54, and it is limited to the intermediary server 56 that is combined with the remaining part. There is no risk of misuse of personal information even if intercepted by a third party.
Further, since the intermediary server 56 is interposed, there is no risk that personal information is accumulated in the Web server 66 operated by the personal computer shop, the chain headquarters, the manufacturer, or the like.
Even in the intermediary server 56, only a part of the encrypted product information is stored in the database, and even if temporarily merged with the remaining part at the time of the search process, Erased from above. For this reason, even if the information in the server 56 is taken by a third party, there is no risk that valuable personal information will be leaked outside.

Of course, instead of the terminal 12 in the store, the mediation server 56 can be accessed from the personal computer 52 at home via the Internet 54 and a search for related information can be requested.
In this case, a function similar to that of the related information providing unit 32 is realized by the CPU of the personal computer operating in accordance with a dedicated application program.

As described above, instead of reading the product code from the RFID tag 30 affixed to the warranty card 16 via the reader / writer 22, the product code displayed in the barcode on the product packaging box or the warranty card 16 is read by the barcode reader. It can also be done.
Alternatively, the product code may be manually input using a keyboard.

In the above, “purchased product information” is exemplified as personal information, but the present invention is not limited to this.
For example, the code of an unpurchased product that the user is personally interested in is encrypted and registered in the RFID tag 28 of the membership card 14, and the related information is displayed on the display 18 of the in-store terminal 12 each time the customer visits the store. If operated to display, it is possible to guide the user to purchase the product.
Specifically, on the list screen 36 in FIG. 5, when the user touches the “add other product” button 68, a list of products handled at the computer shop is displayed on the display 18. When a specific product is selected, the code of the product is encrypted by the personal information registration unit 24 and registered in the RFID tag 28 of the member card 14 via the reader / writer 22.

Alternatively, when the user touches the “Add personal information other than product” button 70 on the list screen 36, a screen for selecting attributes such as gender, age, annual income, occupation, hobby, personal computer history, etc. is displayed. (Not shown).
On the other hand, when the user touches and selects a necessary attribute, the personal information registration unit 24 encrypts the code indicating the personal information and stores it in the RFID tag 28 of the member card 14 via the reader / writer 22. .
Thereafter, when the user puts the membership card 14 on the reader / writer 22 of the in-store terminal 12, the product information associated with the registered personal information is extracted by the related information providing unit 32 and displayed on the display 18. become.
For example, when a user registers personal information “age: 60s” and “personal computer history: less than one year” in the RFID tag 28 of the membership card 14, the related information providing unit 32 of the in-store terminal 12 Then, product information that matches the above two personal information is extracted from the in-store database 34 and displayed on the display 18.

Further, the user can delete the product information once registered in the RFID tag 28 of the membership card 14 at any time.
For example, in the list screen 36, when the user touches the “delete” button 72 related to a specific product, the corresponding encrypted product information is deleted from the RFID tag 28 of the member card 14 by the related information providing unit 32, and thereafter The related information of the product is not displayed on the display 18 of the terminal 12 in the store.
