  When targeting an unspecified communication partner, it is often a new communication partner for the connected side, and in many cases it cannot be handled by a method of previously registering a verification target. In addition, when a person other than the owner of the telephone number performs communication by temporarily borrowing the communication terminal of the corresponding telephone number, it is difficult to confirm the person who actually communicated.

  Therefore, an object of the present invention is to provide a network system that enables identity verification and a communication terminal used therefor.

  In order to solve this problem, the network system according to the present invention includes an issuing means for issuing a personal identification number unique to the user of the originating communication terminal, stores credit information, and corresponds to the issued personal identification number. Database means for issuing a reference number for referring to the credit information when there is valid credit information, and notification means for notifying the reference number issued by the database means to the receiving communication terminal; The receiving communication terminal refers to the credit information from the database means based on the reference number.

  It is possible to provide a network system that enables identity verification and a communication terminal used therefor.

  FIG. 1 is a diagram illustrating an example of the configuration of a network system. In FIG. 1, 10 is a personal authentication system, 20 is a communication terminal on the transmitting side that connects to the personal authentication system and inputs a personal identification number (hereinafter referred to as a personal ID), and 30 is a network to which the communication terminal 20 is connected. Reference numeral 40 denotes a reference ID notification system, which inputs the principal ID from the calling communication terminal 20 via the network 30. Reference numeral 50 denotes a credit information database connected to the network 30, and the sender ID is input from the reference ID notification system 40. The credit information database 50 further checks whether valid credit information corresponding to the principal ID exists, and outputs a reference number (hereinafter referred to as a reference ID) for referring to the credit information to the reference ID notification system 40. The credit information is information used to determine whether or not it is worth providing credit.

  Reference numeral 60 denotes an incoming communication terminal, which is connected to the outgoing communication terminal 20 via the network 30. In particular, the receiving communication terminal 60 receives a reference ID from the reference ID communication system 40 via the network 30 and downloads credit information from the credit information database 50 using the reference ID.

  The principal authentication system 10 needs to issue a principal ID associated with the credit information in the credit information database 50. As a method of personal authentication, for example, a method using biometric authentication technology such as fingerprint, retina, vein, etc. can be considered, but other authentication methods may be used as long as the personal ID can be issued. The identity ID does not necessarily have to be a constant value, and safety against eavesdropping should be considered.

  The caller communication terminal 20 is a terminal to which the user authentication system 10 can be connected, and can notify the reference ID notification system 40 of the user ID in the course of the transaction process with the network at the time of call. .

  The reference ID notification system 40 requests the credit information database 50 to perform a valid registration check based on the notified principal ID. In this system, this process is executed each time a call is made. If there is valid information, the credit information database 50 issues a temporary reference ID to the reference ID notification system 40. That is, in order to reduce the risk of eavesdropping on the reference ID, in this embodiment, the reference ID is changed every time transmission is made. If there is no valid information, a test failure is notified.

  The reference ID notification system 40 can notify the rewriting / receiving communication terminal 60 of the caller ID display information area that is originally notified to the called side by a call connection message in accordance with the requested inspection result. When the reference ID is issued, it is rewritten with a reference code and a control code indicating that the incoming call has an ID that refers to the credit information. If the inspection result is unacceptable, the original caller ID information is notified to the receiving communication terminal.

  The destination communication terminal 60 changes the operation according to the content of the caller ID display information when receiving an incoming call. This point will be described with reference to the flowcharts of FIGS. FIG. 2 is a flowchart for explaining the operation when receiving an incoming call, and FIG. 3 is a flowchart for explaining the operation when communication is disconnected.

  As shown in FIG. 2, when an incoming call is received via the network 30, first, the control code is checked to determine whether or not the credit information has a reference ID (step 601). The ID is acquired (step 602), and the fact that this incoming call is an incoming call with a reference ID of credit information is displayed to the user instead of the caller ID information (step 604). If the reference ID is not added, the process proceeds to other incoming call processing (step 603). After step 604, the user looks at the display and determines whether to respond to this incoming call, and performs the corresponding operation (step 605). If no response is made, the process proceeds to an incoming call rejection process (step 607). If an answer is made, an incoming call response and connection process (step 606) is performed, and the process proceeds to a call state (step 608).

  At the time of disconnection, as shown in FIG. 3, when a disconnection request is received from the user, a communication disconnection process (step 610) is performed, and then it is determined whether a reference ID is attached or received based on the presence or absence of the reference ID acquired earlier (step 610). 611). If the reference ID is attached, the credit information database 50 is accessed via the network 30 to refer to the credit information (step 612). If the reference ID is not added, the process proceeds to other disconnection display processing (step 613). When the credit information is referred to, the obtained credit information is displayed in association with the previous incoming call (step 614). Here, it is assumed that association with the incoming time information is performed. As a display example, the one shown in FIG. 4 can be considered. FIG. 4 is a display example of the credit information of the receiving communication terminal 60. Name information (6141), affiliation (6142), contact information (6143), still image data (6145), and incoming time (6144) based on clock data. Of these, 6144 is not downloaded data but data added by the destination communication terminal 60. Concerning the display of such credit information, for example, the GUI is configured so that the cursor can be moved to and selected from the contact information, and the convenience is improved by providing a function for performing automatic transmission according to the selection operation. . The still image data (6145) is effective for identity verification when it has a TV phone function. Now, after carrying out storage processing (step 615) so that this credit information and related data can be re-displayed arbitrarily, the communication terminal shifts to a standby state (step 616).

  According to the present embodiment, it is possible to determine whether or not the credit information can be referred to when an incoming call is received for an unspecified unknown source, and in some cases, it is possible to determine whether to reject the incoming call. In addition, the identity of the called party can be immediately confirmed after the disconnection request. Further, since the credit information is specified using the personal ID, the personal identification can be performed regardless of the caller telephone number used.

  It can be assumed that some communication terminals have multicall and multiconnection functions. In this case, the processing corresponding to steps 612 to 615 shown in FIG. 3 can be executed during the incoming call.

  The network system is not limited to the example of FIG. For example, as shown in FIG. 5, the personal authentication system 11 may be arranged so as to face the transmission side communication terminal 21 via the network system 30. That is, it is assumed that the personal authentication system 11 performs the personal authentication procedure via a network. In this case, the personal ID is notified directly from the personal authentication system 11 to the reference ID notification system 41. For example, the transmission side communication terminal 41 is assumed to include an authentication processing execution medium and a password input GUI.

  According to this system, on the receiving side, identity verification can be performed for an unspecified communication partner regardless of possession of the telephone number of the caller, and safety can be improved.
