BEST MODE FOR CARRYING OUT THE INVENTION In order to realize the same simplicity as a paper business card and to guarantee the authenticity of information, the electronic business card of the present invention has personal information necessary for providing information as a business card, a business card ID,
The feature value data obtained from the personal information and the access destination information of the system for authenticating the information are composed of the authentication information watermarked by using the digital watermark technique. The format of the electronic business card may be an HTML document or a document file format that can be read by general-purpose document creation software. The authentication information is
JP-A-11-239129 and JP-A-2000-18
It is embedded in an image file as a digital watermark in image information using the Internet mark method as disclosed in Japanese Patent No. 7442 or image information created by other means. When using the Internet Mark method,
By clicking the image containing the digital watermark, the authentication information is automatically transmitted to the access destination of the authentication system, and as a result, the authentication result is returned. The personal information may be composed only of character data, or may include image information such as a facial photograph of the person. In the latter case as well, it is possible to create feature value data including image information and embed it as a digital watermark.

An electronic business card system including an electronic business card creation management system and an electronic business card authentication system is provided to create and manage this electronic business card and authenticate the authenticity of information. First, an electronic business card authentication system that performs electronic business card authentication processing will be described.

An electronic business card authentication system server is installed in an organization to which a business card is created, such as a company, or an organization entrusted by the organization. The electronic business card authentication system includes an authentication information database for authenticating information of an electronic business card and an electronic business card authentication unit. The authentication information database is
Each electronic business card has a business card ID uniquely set, feature value data regarding personal information, an identifier as to whether or not the business card information is the latest information, and information on the creation date of the electronic business card which is the data update date. Since this information does not include personal information composed of plain text, even if the data is leaked by external access, there is no risk of personal information being leaked unless a key for decrypting the characteristic value data is obtained.

When an inquiry is made from the electronic business card recipient to the authentication system, the authentication system collates the transmitted inquiry information with the information in the authentication information database to create a determination result and send it back. When the present invention is configured by using the Internet mark technology, the authenticity of the business card information is confirmed mainly by accessing the Web page by the watermarked URL through the network. The application that performs this process is provided as add-in software, but the program information may be watermarked in the watermark information. The authentication system first recognizes the business card ID from the inquiry information and checks whether the corresponding business card ID exists in the authentication information database. If it does not exist, move to authentication error processing. When the corresponding business card ID is detected, the feature value data in the inquiry information is then compared with the feature value data corresponding to the business card ID. If this data does not match, the process moves to authentication error processing.

The matching of the corresponding feature value data with the business card ID means that the business card information is correct, but this does not mean that the "information is correct" as it is. That is, when the target person of the business card is transferred,
This is "incorrect" when compared to current subject information
Therefore, the latest identification code of the corresponding record in the authentication information database is determined next. If this is the latest code, it means that the information is correct, so the system returns the result of authentication OK and ends the process. In the case of "data is correct but not the latest information", a result message indicating that is returned and the process is terminated.
The error processing returns a result message indicating that the information is incorrect and ends the processing. When a database for managing the authentication history is set in the system, the business card ID inquired here, the verification date, and the authentication result information are stored as a set. At this time, address information of the inquiring user may be acquired and stored.

The electronic business card according to the present invention includes a company name, affiliation,
Since personal information data such as name and telephone number is displayed on the terminal as it is, it plays the same role as a conventional business card, and authenticity of the information is guaranteed by performing an authentication operation only when necessary. Further, by adding a face photograph of the person as the information of the electronic business card, it is possible to prevent impersonation of another person. As the image information in which the watermark information is inserted, this face photograph or a company mark or the like may be used. The distribution of the electronic business card of the present invention stores the electronic business card file in the personal mobile terminal,
This is done by copying and transmitting this. It is also possible to provide a business card distribution management system on a mobile terminal and create a business card distribution management database by inputting the issue date and the information of the distribution destination every time the electronic business card is issued. Further, the electronic business card of the present invention can be used as a normal paper business card by printing.

Next, the configuration of the electronic business card creation management system for creating an electronic business card and managing the latest authentication data according to the present invention will be described. The electronic business card creation management system has an electronic business card creation unit, an information management unit that manages the latest creation of the electronic business card, and the information in the authentication information database. A business card basic information database that stores common information such as a history database, company name logo, mark, location, representative telephone number, slogan, and a business card storage unit that stores the created electronic business card file. Work with. The personal information database is kept up to date by coordinating with the personnel information system or periodically obtaining information. By making the basic business card information database independent, even if the company name is changed or the office is relocated, it is only necessary to update the data in one place. When there is a change in the personal information database or periodically, the electronic business card creation unit starts business card creation processing.

The personal information database includes a personal identification number,
It has data items such as name, affiliation, telephone number, and information update date indicating a transfer date. In addition to this, the personal information database may be provided with personal information such as an email address, a name and alphabet, a facial photograph file name, an extension number, and data update item information. The business card history database is a personal identification number, business card I
D, it has an identifier of whether it is the latest information and a data item of a business card creation date corresponding to the transfer date. Actually, the day when a business card is created is often before or after the transfer date,
In terms of data management, it is preferable that the transfer date = business card creation date, so the “business card creation date” used here is not the date on which the business card file was actually created, but the transfer date.

The target person extraction function of the electronic business card creation unit collates the personal information database with the business card history database by the personal identification number to extract the business card creation target person. If the information update date of the personal information database is newer than the creation date of the data having the latest code in the business card history database, it is determined that the person is a business card creation target person. Next, the unique business card ID that the business card ID setting function does not duplicate with the data in the business card history database
To set. This function updates the latest number based on the personal identification number
It may be configured by a simple logic such as adding 1, as long as the uniqueness is maintained. Next, the business card data creation function extracts the personal information required for business card creation from the personal information database for the target person. The feature value data creation function creates feature value data from this personal information. The watermarked information creating function creates watermarked image information by watermarking the feature value data, the business card ID and the access destination information as digital watermarks on predetermined image data such as the face photograph data of the target person or the company mark.

Finally, the business card file creation function extracts basic format information from the business card basic information database, creates a new electronic business card file together with personal information, watermarked image data and creation date, and gives a name by which an individual can be identified. And stores it in the business card storage section. A new electronic business card can be obtained by sending this file to the target person or by accessing the system and downloading the file.

Next, the information management unit performs a database update process. First, the target person information updating function searches for a record having the latest code from the corresponding data in the business card history database by the target person personal identification number, and updates the code of the data to the code indicating the old information. At the same time, the corresponding data in the authentication information database is searched by the business card ID of this record, and the latest identification code is updated to the old code. If the authentication information database has a data end date, enter the value of the day before the creation date of the new business card as the end date. Next, the new business card data adding function stores the created business card ID, the personal identification number of the target person, the creation date, and the latest code in association with each other in the business card history database. At the same time, the business card ID, the characteristic value data created at the time of creating the business card file, the latest code, and the creation date of the business card are stored in association with each other in the authentication information database. As described above, the information in each database is updated to the latest information.

Each history record has a data structure including a personal ID, a business card ID for uniquely identifying business card data, a latest code indicating whether or not the business card information is the latest, a business card creation date, and an end date. It can be obtained from the information database 231 and is not used for the purpose of the present invention, so it need not be provided.
Here, since the business card data is associated with the personal ID, a record number is separately set as an index, but since the business card ID is a code that does not overlap, the personal ID may be associated with this as an index. This database is a personal information database 22
If the timing of updating 1 and the business card creation process are different,
Although it prevents the creation of new business card data that has already been created, it can also be used for the purpose of displaying the history of business cards created by an individual since joining the company.

FIG. 11 shows an electronic business card creation management system 22.
It is a figure which shows the flow of the process of 0. A processing procedure of the electronic business card creation management system 220 for creating an electronic business card and managing the latest information will be described with reference to FIGS. 8 to 11. The target person extraction unit 821 of the electronic business card creation management unit 225 uses the personal ID for the personal information database 221 and the business card history database 22.
3 is collated, and the business card creation target person is extracted (step 11).
01). The extraction condition is determined to be a business card creation target person when the update date of the personal information database 221 is newer than the creation date of the record in which the latest code of the corresponding personal business card history database 223 is "New" (step 11).
02 Yes). Taking the data of FIG. 9 and FIG. 10 as an example, the personal ID “00” whose update date of personal information is 01/03/01
The personal data of “0112” is the target. Next, the business card ID setting unit 822 sets the business card ID in the business card history database 223.
Set a unique business card ID that does not overlap with (Step 11
03). Next, the business card data creation unit 823 extracts personal information necessary for creating a business card from the personal information database 221 for the target person, and creates business card data (step 1
104). Here, the information about the department, name, English name, mail address, telephone number, and face photo is extracted and used as business card data.

Next, the characteristic value data creating section 824 creates characteristic value data from this business card data (step 110).
5). The characteristic value data is a function value of a function having business card data as a variable, and is, for example, a hash function value by a hash function. The watermarked information creating unit 825 converts the characteristic value data, the business card ID set in step 1103, and the authentication access destination information, which is the address of the electronic business card authentication system 230, into predetermined image data such as the face photograph data of the target person or the company mark. Image data watermarked as a digital watermark is created (step 1106). Here, the access destination information is not watermarked on the image and is one of the information items of the electronic business card.
In this case, it is set as information that is not displayed on the screen. Next, the business card file creation unit 826 extracts basic format information such as a company logo, a mark, a work address and a representative telephone number from the business card basic information database 222, and combines the business card data, the watermarked image data, and the creation date with each other. Then, a new business card file is created, and a file name including the personal name is given and stored in the business card storage unit 224 (step 1107). The electronic business card file stored in the business card storage unit 224 is stored in the business card storage unit 22 by the target person.
4 is stored in the user terminal 11 and used as an electronic business card. The business card file creation unit 826 adds the personal ID of the new business card creator to the temporarily created target person list file.

After the new business card data is created, the electronic business card creation management unit 225 updates the latest data up to that point in the business card history database 223 to the old data and adds the newest data based on the new business card creator personal ID list. I do. First, the target person information updating unit 831 determines that the business card history database 225
The record having the latest code "New" is searched from the data corresponding to the personal ID of the subject who created the business card file from and the code of this record is updated to the old code "Old" (step 1108). Here, the individual I in FIG.
Record number "000023" having D "000112"
The latest code of the record "5" is set to "Old" and the date before the creation date is input to the end date. An example of the updated business card history database 223 is shown in Fig. 12. Next, by the business card ID corresponding to the individual ID. The subject information updating unit 831 searches for the corresponding data in the authentication information database 231, and updates the latest code from Yes to No (step 1109).
Here, the latest code of the record number “000024” of the business card ID “0001122” of FIG. 4 is Old, and the date before the creation date is input to the end date. An example of the updated authentication database is shown in FIG.

Next, the new business card data adding unit 832 stores the created business card ID, the personal ID of the target person, the creation date, and the latest code in the business card history database 223 in association with each other (step 1110). In FIG. 12, the record number "00"
The record of "0909" corresponds to this.

Similarly, the new business card data adding unit 832 stores the new business card ID “0001123” of the subject, the characteristic value data, the latest code, and the creation date of the business card in association with each other in the authentication information database 231 (step 1111).
In FIG. 13, the record with the record number “000233” corresponds to this.

The above processing is repeated until there is no unmatched data in the business card history DB 223 (step 1112).
As described above, the contents of the business card history database 223 and the authentication information database 231 are updated to the latest information. The procedure of updating and adding the data corresponding to the corresponding personal ID after the creation of one business card file may be performed without separately performing the new business card creation and the information update processing collectively.

The user terminal 11 accesses the electronic business card creation management system 220 according to the user's instruction, downloads the electronic business card file of the user from the business card storage section 224 to the user terminal 11, and displays it on the display device. At this time, the electronic business card is transmitted on the network 250 as a computer-readable electronic business card.
