Description

  The present invention relates to an electronic business card certification method and system, and more specifically, when an electronic information business card (electronic business card) is exchanged using a terminal device, for example, a mobile terminal device such as a mobile phone. The present invention relates to a method and a system for guaranteeing and proving that the electronic business card itself or its contents are valid. The present invention also relates to an electronic business card proving device and a terminal device for constituting such a system.

  Conventionally, personal information has been printed on a so-called business card size card. However, business cards tend to be converted to electronic information in accordance with IT in recent years. Such an electronic information business card, that is, an electronic business card is stored as electronic information in a terminal device, for example, a mobile terminal device such as a mobile phone, so that the terminal devices are directly connected by a cable or infrared communication. It is also possible to perform so-called business card exchange by directly transmitting and receiving by short-range dedicated wireless communication such as Bluetooth (see Patent Document 1).

  By the way, in the case of a conventional card-type business card, it was possible to make a business card with a false content by ordering it from a “business card shop” in the town. Furthermore, the recent enhancement of functions of personal computers and printers enables individuals to create business cards of any content very easily. The situation is the same for an electronic business card, and there is no guarantee that the content of an electronic business card arbitrarily created by an individual is authentic. For this reason, for example, in Patent Document 2, the contents of an electronic business card certified as a witness by a third party are registered in the server and the mobile terminal device, and when requested by the mobile terminal device, the server can execute the mobile terminal. An invention is disclosed in which the content of an electronic business card is allowed to be output to the device, thereby enabling the electronic business card to be output for the first time from the mobile terminal device.

  However, in the invention disclosed in Patent Document 2, there is a possibility that such a guarantee is not made for the side that receives the electronic business card, and the contents of the electronic business card stored on the portable terminal device side are not understood. It may have been tampered with for the convenience of the person. In order to prevent falsification of the contents of the electronic business card stored on the portable terminal device side, the contents of the electronic business card are registered in a secure server or the like, and information for identifying the electronic business card, for example, an electronic business card is stored. It is conceivable to replace the assigned ID and the like and access the server with this ID to download an electronic business card (see Patent Documents 3 and 4).

In addition to the above-described configuration, storing information on a large number of electronic business cards in a mobile terminal device such as a mobile phone wastes memory capacity, and when a mobile phone is replaced. Since it is necessary to reinstall the data, and if the contents of the memory are destroyed due to a submergence accident, etc., all of the data will be lost, so each mobile terminal device stores only information identifying the electronic business card. There is also known an invention in which the main body of an electronic business card, that is, the contents of the electronic business card is downloaded to the mobile terminal device each time by accessing the server with this information (see Patent Document 5).

FIG. 10 is a schematic diagram showing a display state of the screen 227S of the display unit 227 of Mr. B's mobile phone 22 in this case. The business card information of Mr. A and the public certification authority (public certification authority 3) ) Certificate is displayed together.

  By the way, Mr. A's electronic business card downloaded to Mr. B's mobile phone 22 as described above is stored in the memory 224 of Mr. B's mobile phone 22, and the Mr. B's mobile phone 22 is operated. It can be displayed on the display unit 227 at an arbitrary time. However, a user DB 15 is prepared in the service site 1, and when Mr. B is a registered user of the service site 1, an electronic business card album for Mr. B is prepared in the user DB 15.

  For example, when Mr. B's mobile phone 22 receives the password from Mr. A's mobile phone 21, the position specifying information by the GPS function provided in Mr. B's mobile phone 22 or the nearest mobile phone The location information of the relay station and the time (year / month / day / hour / minute) at that time can be associated with each other and registered in the electronic business card album for Mr. B in the user DB 15 of the service site 1. Furthermore, before and after the time when Mr. B's mobile phone 22 received the password from Mr. A's mobile phone 21, Mr. A's face photograph was taken with the CCD camera 222 of Mr. B's mobile phone 22, and this image information was also added to the user. It is also possible to register in the electronic business card album for Mr. B in the DB 15 for use.

  In the above case, the memory 224 of Mr. B's mobile phone 22 extracts and stores the name of the person from the electronic business card received from the other person's mobile phone, and displays the person name in a list for selection. It is possible to easily configure an electronic business card of an arbitrary person so that it can be downloaded from the user DB 15 of the service site 1 and viewed at an arbitrary point of time using a known technique.

  In the case of adopting the configuration as described above, since the electronic business cards of a large number of persons are not stored in the own mobile phone, only the personal names need be stored on the mobile phone side. It is possible to effectively use the memory capacity of the mobile phone, and even if the mobile phone is replaced or lost, the electronic business card can be used in the same way as before without troublesome data backup and reloading. It is possible to browse.

  As described above in detail, according to the present invention, the business card information authenticated by the public third party organization is stored in the server without being stored in the individual personal digital assistant device (mobile phone), and the electronic business card is stored. Since it is transmitted directly from the server to the mobile terminal device of the scolding person, there is no possibility of falsification within the mobile terminal device of the owner of the business card information. In addition, since the person receiving the electronic business card acquires personal authentication information such as a fingerprint of the owner of the business card information with his / her mobile terminal device and transmits it to the server, so-called impersonation can be prevented. Since it is possible to confirm that the received electronic business card information has been authenticated by a public third-party organization, the received electronic business card information can be sufficiently trusted.
