Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic business card providing method and an electronic business card providing apparatus. The present invention particularly relates to a technique for acquiring information to be registered as an electronic business card from a user and publishing the information for browsing on a network.
[0002]
[Prior art]
Conventionally, business card exchange has been indispensable as a business habit, but management of received business cards is complicated. In order to support the business card management, a method of electronically managing the contents of the business card by inputting the contents of the business card into a computer is considered. Although a method of digitizing information using a scanner is also conceivable, there is no much difference from the case where a scanner is not used in terms of the complexity of having to input data one by one. On the other hand, data to be posted on a business card can be handled by a portable terminal such as a PDA (Personal Digital Assistants) or a mobile phone. In this case, business card data can be exchanged using infrared communication or wireless communication from a close distance of the partner terminal.
[0003]
[Problems to be solved by the invention]
However, business card exchange in a portable terminal is limited by compatibility of hardware and software, etc., and has not yet become widespread as a technique for replacing a business card using a conventional paper medium. In addition, management is confused on the contrary if the other party is forced to use the electronic medium and the paper medium properly. Therefore, it was considered that there is a potential demand for a technology that can also be used with a conventional business card and that facilitates data management.
[0004]
The present inventor has made the present invention based on the above recognition, and aims to provide a technology for efficiently exchanging and managing information by fusing an electronic business card registered on a network with a business card printed on paper. It is in. Another object is to provide a technique for efficiently realizing various information exchanges performed in association with business card exchange.
[0005]
[Means for Solving the Problems]
One embodiment of the present invention relates to an electronic business card providing method. In this method, in order to create an electronic business card in a virtual world in which a business card in the real world is digitized, a step of obtaining the contents of the business card to be digitized from a user who is the person himself, and a user used to specify the electronic business card A process of issuing a business card ID, which is unique identification information to be posted along with a name in a business card in the real world, to a user who is a principal, and arranging the contents of the business card, the business card ID, and a URL indicating a site for viewing electronic business cards. A step of generating electronic business card data by determining a business card layout; a step of storing electronic business card data in association with a business card ID in a storage device; and collecting and storing another user's business card ID for each user. And generating a business card collection for performing a business card collection, and, when a business card ID is specified as a browsing target by a user serving as a viewer, the business card ID corresponds to the specified business card ID. Extracting the electronic business card from the storage device and transmitting the electronic business card to the user as a viewer, registering the business card ID to be viewed in the business card collection based on the instruction of the user as the viewer, and Notifying the registered user of the electronic business card of the fact that the registration has been made and the business card ID of the user who performed the registration, and performing the registration in the business card collection of the user who received the notification. Mutually registering the user's business card ID.
[0006]
A "business card in the real world" is a card that describes the name and status of an individual, and is exchanged with a business partner who is particularly new to business. The electronic information of the name and the like described in this business card is “electronic business card in a virtual world”, and it is assumed that the electronic business card is mainly downloaded from a server via the Internet and displayed on a screen. The “business card ID” is information unique to the user who has been issued an electronic business card, and the user or another person downloads a desired electronic business card by designating the business card ID. This business card ID is used not only in the virtual world but also on the business card in the real world. That is, the other party receiving the business card on which the business card ID is posted can access the server that manages the electronic business card and acquire the electronic information of the business card based on the business card ID. “Principal” is not intended to be strictly limited to one individual who is the person himself / herself. For example, in the case of a company contract, the manager or the person in charge of the company may be permitted to act on behalf of issuance procedures.
[0007]
The “business card collection” is an area in which business card IDs of the partners whose business cards are exchanged by a certain user are mainly collected, and are managed for each user. For example, the information may be managed in the same manner as an address book, an e-mail address book, a URL bookmark, and the like. When the first user registers the business card ID of the second user in the business card collection of the first user, the fact is notified to the second user and the first business card collection of the second user is similarly registered in the business card collection of the second user. The business card ID of the user is automatically registered.
[0008]
Generally, after a business card exchange in the real world, the person who exchanged the business card individually inputs the contents of the business card, for example, a name and an e-mail address, into a computer. According to this aspect, it is possible to acquire the electronic data of the contents of the business card only by inputting the business card ID, and to automatically obtain the electronic data from each other only by inputting the business card ID by one of the business card exchangers. . As a result, it is possible to save the trouble of inputting the business card data which has been performed repeatedly.
[0009]
Another embodiment of the present invention relates to an electronic business card providing device. This apparatus uses an electronic business card in a virtual world in which a business card in the real world is digitized, and a business card ID which is user-specific identification information used to identify the electronic business card and which should be posted on the business card in the real world. An issue unit for issuing to a certain user, an electronic business card storage unit for storing electronic business card data in association with a business card ID, and a business card collection for collecting and storing another user's business card ID for each user A business card collection storage unit, a display processing unit that extracts and transmits an electronic business card corresponding to the specified business card ID from the electronic business card storage unit when a business card ID is specified as a browsing target, and a business card ID to be viewed. And a registration processing unit for registering the business card collection based on an instruction of a user who is a viewer. The registration processing unit notifies the user who is the principal of the electronic business card registered in the business card collection of the fact that the registration has been made and the business card ID of the user who has performed the registration, and the business card collection of the user who has received the notification. , The business card ID of the user who has made the registration is reciprocally registered.
[0010]
The present device may be mainly realized as a server that holds electronic business cards of a plurality of users on a network and returns data of the electronic business cards in response to a browsing request from a user terminal. The electronic business card storage unit and the business card collection storage unit may be each realized as a storage device in terms of hardware.
[0011]
Also in this embodiment, the business card contents can be acquired only by inputting the business card ID, and the input of the business card ID may be performed only on one of the sides that exchanged the business card. This can save the trouble of inputting duplicate business card data. Further, since the management of the business card data is performed collectively on the server, the company can use the business card data in an outsourcing manner in a department unit or a company unit.
[0012]
As another form, the present device includes both a case where the device refers to a server or a user terminal installed on a network and a case where the device refers to a system including a server and a user terminal connected via a network. Each functional block of the display processing unit and the registration processing unit may be provided on the server side or may be provided on the user terminal side. It may be provided in both the server and the user terminal, and in that case, each functional block may have the same name. Each of these functions is provided in the form of a program module, and may be executed by one or both of the server and the user terminal, or may be downloaded from the server to the user terminal upon execution.
[0013]
It should be noted that any combination of the above-described constituent elements, and those in which the constituent elements and expressions of the present invention are mutually substituted among methods, apparatuses, systems, computer programs, recording media storing computer programs, data structures, and the like, are also included. This is effective as an aspect of the present invention.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an example of a business card layout in the real world in the present embodiment. As shown in the figure, a business card ID 102 and a browsing site URL 104 are listed below the name, address, and telephone number on the paper of the business card 100. As a result, the identification information of the own electronic business card and the site where the user can browse the electronic business card are transmitted to the partner who has exchanged the business card. The other party who has received the business card 100 can access the site based on the viewing site URL 104 and enter the business card ID 102 to view the electronic business card. When a business card with a business card ID is exchanged, the other party's electronic business card can be viewed with each other.
[0015]
On the other hand, the business card ID of the viewed electronic business card can be registered in its own business card collection. After the registration, the own business card ID is automatically registered in the business card collection of the other party. At this time, a method of registering with the consent of the other party can also be selected. In this case, a notification that the registration has been made and a request for consent are sent to the other party by e-mail or the like, and automatic registration is executed when a reply is received.
[0016]
In this way, mutual registration of business card IDs is realized only by one of the business card exchangers registering the other party's business card ID in the business card collection. Therefore, duplicate data input and input mistakes can be avoided, and business card data can be managed efficiently.
[0017]
FIG. 2 shows a configuration of the electronic business card providing system according to the embodiment. The electronic business card providing system 10 includes a plurality of user terminals 12 connected via a network 16 and an electronic business card providing server 14.

In FIG. 3 to be described, functional blocks realized by their cooperation are depicted. Therefore, these functional blocks can be realized in various forms by a combination of hardware and software.
[0019]
FIG. 3 is a functional block diagram illustrating a basic configuration of the electronic business card providing server according to the embodiment. The electronic business card providing server 14 includes a communication unit 20, an issuing unit 22 that issues an electronic business card and a business card ID, an electronic business card storage unit 38 that holds electronic business card data in association with the business card ID, and a business card collection for each user. , A registration processing unit 30 for registering a business card ID in a business card collection, a display processing unit 32 for transmitting an electronic business card to a viewer, and an authentication unit 40 for authenticating a viewer of the electronic business card. Have. The electronic business card providing server 14 obtains additional information to be displayed as supplementary information of the electronic business card from the user who is the principal, and stores additional information that stores the additional information in association with the business card ID of the user who is the principal. A unit 48, a condition setting unit 42 for setting conditions relating to browsing authority for the electronic business card and the additional information based on an instruction of the user who is the principal, and an authority setting storage unit 44 for holding the conditions. Each unit transmits and receives data to and from the user terminal 12 on the network 16 via the communication unit 20. The communication unit 20 may have a router function or a server function in addition to the data transmission / reception function.
[0020]
The issuing unit 22 includes a business card setting unit 24 that obtains information such as a name, a company name, a title, an address, and a telephone number that are published on a business card in the real world from a user who is the person who is issued the electronic business card, and the user Includes an ID setting unit 26 that issues a business card ID serving as identification information to the user. The contents and the business card ID of the electronic business card acquired and issued by the issuing unit 22 are stored in the electronic business card storage unit 38. The authentication unit 40 obtains its own business card ID and password from the viewer and authenticates himself. A viewer who does not have a business card ID may be authenticated using an e-mail address.
[0021]
The authority setting storage unit 44 stores the layout of the electronic business card and the definition of the combination pattern of the additional information. For example, the definition of the layout of the electronic business card to which the information for business is added, the definition of the layout to which the information for the company is added, and the like are set, and these are stored in the authority setting storage unit 44. For each of these definitions, the conditions of the browsing authority are set in association with the business card ID or the e-mail address of the partner to whom browsing is permitted. Thus, different display contents can be transmitted depending on the other party.
[0022]
The display processing unit 32 obtains, from the viewer, the unique business card ID of the electronic business card to be viewed from the viewer, and the electronic business card and the additional information corresponding to the specified business card ID from the electronic business card storage unit 38. And a content selection unit 36 to be extracted and transmitted. On the other hand, the unique information receiving unit 34 acquires not only the business card ID to be browsed but also information unique to the viewer, and compares this with the conditions held by the authority setting storage unit 44. The information unique to the viewer may be, in addition to the business card ID of the viewer, the e-mail address of the viewer if the viewer does not have the business card ID. The content selection unit 36 selects the content according to the collation result as the content of the electronic business card and the additional information to be transmitted to the viewer. A part of the electronic business card may be concealed from the reader of the business card ID or the e-mail address which is not defined in the condition of the browsing authority stored in the authority setting storage unit 44 to prevent information leakage.
[0023]
The registration processing unit 30 registers the business card ID to be viewed in the business card collection of the viewer in response to a registration instruction from the viewer, and informs that the registration has been made to the user who is the registered electronic business card. The business card ID of the registered user is notified. In addition, the business card ID of the user who has performed the registration is reciprocally registered in the business card collection of the user who has received the notification. Mutual registration will be notified to both parties.
[0024]
Mutual registration may be performed subject to the consent of the user who has received the notification in advance. For example, when notifying by e-mail, the URL is described in the body of the e-mail in the form of a character string that passes an argument to a CGI (Common Gateway Interface) that executes automatic registration. On the receiving side of the e-mail, by double-clicking the URL part, an argument indicating "agreement" can be passed to the CGI. Thereby, mutual registration is realized by a simple method. Also, a message for improving the friendliness of the other party may be set in advance as the text of the e-mail.
[0025]
Another form of the mutual registration may be realized by a method in which after the automatic registration is executed, the fact is notified afterwards, and the registration is canceled if the side receiving the notification does not agree.

The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and that such modifications are also within the scope of the present invention. Hereinafter, modified examples will be described.
[0039]
In the embodiment, the electronic business card providing server 14 is configured to acquire the business card ID or the e-mail address of the viewer by the authentication at the time of login. However, the acquisition timing does not necessarily have to be at the time of login. For example, a format in which the user's own business card ID is input at the time of specifying the business card ID to be browsed, or a format in which the user's own business card ID is automatically transmitted from the user terminal 12 to the electronic business card providing server 14 may be used.
[0040]
In the embodiment, the business card ID of the electronic business card being viewed is registered when a registration instruction to the business card collection is issued, but the registration target may not be the business card ID being viewed. For example, a configuration may be employed in which a plurality of business card IDs to be registered can be simultaneously specified and registered collectively.
[0041]
In a modified example, the character string of the business card ID may be provided with regularity and used for authentication. For example, the business card ID may be a character string having a predetermined regularity for each company to which the company belongs, thereby preventing so-called “spoofing”.
[0042]
In a modified example, the date and time of registration to the business card collection may be recorded. If the date and time of the mutual registration are also recorded, it becomes a record of business card exchange for both parties, and since an input by either one is sufficient, an AC record can be created efficiently.
[0043]
【The invention's effect】
According to the present invention, business card information can be managed efficiently.
