1 is a block diagram of a system for automatically updating subscriber information according to an embodiment of the present invention.

Referring to FIG. 1, an automatic subscriber information update system 100 according to an embodiment of the present invention includes an information provider 10, a communication network 20 and 21, a VAN server 30, and an information cleaning unit 40. ) And a plurality of information using institutions (50).

The information provider 10 serves to receive and maintain personal information of the subscriber. For example, if a subscriber wishes to make a transaction with a reliable institution such as a bank, the subscriber's name, social security number, postal address, e-mail address, landline telephone number, mobile phone number and e-mail address will be submitted. The information provider 10 then stores this subscriber information in an internal database and utilizes it in future credit transactions.

Therefore, in the present invention, a highly reliable institution such as a bank is utilized as the information provider 10. On the basis of the subscriber information registered in the information providing agency 10, the latest subscriber information is continuously maintained for the information user organization 50 such as other offline agencies and internet sites with which the subscriber is trading or subscribing. Will be provided.

At this time, the information provider 10 receives an information utilization consent message for updating the information of the subscriber from the subscriber. In this case, the "information utilization consent message" is a message about allowing the subscriber to provide his or her information to the other information using organization 50 and to provide updated information when there is a change in the personal information.

This information utilization consent message can be entered by the subscriber through the Internet site operated by the information provider institution 10, and also by using a variety of media such as tablets, PDAs, OMR cards, such as 'electronic document' The consent form can be signed and kept. In addition, by using an outbound call (Out Bound Call) such as ARS to the subscriber, the subscriber's voice may be attached to the consent message and used as an information utilization consent message.

The VAN server 30 initially receives the information on the subscriber from the information provider 10, and stores in the internal database (31 to 35). The databases DB1 to DB5 31 to 35 classify and store various subscriber information for each kind of information. For example, DB1 (31) stores information about new or changed telephone subscribers, DB2 (32) stores customer address, map / information information, and DB3 (33) administrative name and postal code. Information about a credit card merchant may be stored in DB4 34, and information about a building and an address may be stored in DB5 35.

The internal subscriber information processing unit 36 provides the subscriber information to the information using organization 50. If the subscriber information is updated, the subscriber information processing unit 36 periodically authenticates the updated information to the information using organization 50. Perform the function provided.

The information cleaning part 40 performs a function of correcting when the subscriber information stored in the databases 31 to 35 is incorrectly input. In addition, the information cleansing unit 40 may automatically update the subscriber information by utilizing reliable information held by the information cleaning unit 40. The function of the information cleaning unit 40 will be described in more detail below.

The information user organization 50 receives various subscriber information from the VAN server 30 as various organizations that allow sharing of subscriber information. For example, the information usage agency 50 may include an insurance / financial institution 51, a public agency 52, a website 53, and other agencies 54 that require up-to-date subscriber information. The information user organization 50 can receive the subscriber information and the update information from the information provider 10 and the VAN server 30 from the beginning, and only future update information for the subscriber information that is independently built by the user. You may be provided.

In the embodiment of the present invention, the information providing organization 10 and the VAN server 30, or the VAN server 30 and the information using organization 50 is connected through a communication network (20, 21). Herein, the communication networks 20 and 21 may be variously implemented according to transmission media as follows. For example, the communication networks 20 and 21 may be configured using dedicated lines. If you use a dedicated line, the security is very high. In addition, the communication networks 20 and 21 may be configured using a virtual private network (VPN). In this case, a VPN refers to a communication network in which a private network is established using a public network such as the Internet. In the case of using a VPN as described above, it may be configured by utilizing an existing built VPN, or installing a separate VPN or installing a S / W VPN Client Module. In addition, the communication network (20, 21) can be configured using a public network. When using a public network that is not secure, such as ADSL, it is required to encrypt the data transmitted. When using a public network as described above, an encryption protocol such as SEED and DES (Data Encryption Standard) or commercially available open SSL can be applied to encrypt data transmitted.

The VAN server 30 and the information cleaning unit 40 may also be connected using a dedicated line, a VPN, or a public network.

2 is a detailed configuration diagram of a VAN server and an information cleaning unit according to an embodiment of the present invention.

2, the VAN server 30 according to an embodiment of the present invention includes a subscriber information processor 36, databases 31 to 35, and input / output interface modules 210 and 211 therein.

The subscriber information processing unit 36 includes a central processing unit 201, an ETL unit 202, an information authentication unit 203, an update information transmission unit 204, a subscriber notification unit 205, and a transaction log DB ( 206).

The central processing unit 201 sequentially controls the subscriber information according to the embodiment of the present invention to other blocks in the subscriber information processing unit 36.

The ETL unit 202 functions to extract and transform necessary subscriber data from the databases 31 to 35 to transmit and load raw data in a step before updating.

The information authentication unit 203 stores the changed subscriber information input from the information provider 10 and the external cleansing information provided from the information cleaning unit 40 in the existing databases 31 to 35. It compares the information and checks whether or not there is a change in the subscriber information. As such, the process of cleaning the subscriber information may be repeated every day, or may be performed on a weekly or monthly basis.

The update information transmission unit 204 transmits the updated subscriber information to each of the operators (51 to 54) included in the information user institution 50. In this case, the information using institution 50 may include various types of organizations and Internet sites 51 to 54, and the various types of subscriber information are different from each other. The form may be different. Accordingly, the type of subscriber information required by the information user organizations 51 to 54 of each update information transmission unit 204 is selected and variously modified into a format required by the operators 51 to 54. Function to transmit.

The subscriber notification unit 206 recognizes that the update is completed when the information of the subscriber included in the information using institution 50 is updated by using the latest subscriber information on which the change or cleansing of the subscriber information is completed. Notify me so. As the method of such notification, the VAN server 30 may send a short message service (SMS) using the mobile phone number of the subscriber, or notify by email using an email address.

The transaction log DB 206 is a database that stores a transmission record for subscriber information provided from the VAN server 30 to the information user institution 50.

In this way, the VAN server 30 can always provide the latest subscriber information to the information using organization 50 by using the subscriber information provided from the information provider 10 and the information cleaning unit 40. . At this time, the VAN system 30 retains the metadata (Meta Data) for the provided subscriber information, the maintenance and management of such metadata is performed by the ETL unit 202 or information authentication unit 203. .

The input interface module 210 restores a signal received from the information provider 10 through the communication network 20 and provides the information to the information processor 36. The output interface module 211 converts the updated subscriber information to the information user organization 50 so that the information can be transmitted through the communication network 21.

The information cleaning unit 40 according to the embodiment of the present invention includes a plurality of information providing organizations CP1 to CP5 41 to 45. The information cleaning unit 40 may provide the latest data on the subscriber information every predetermined period of time (for example, 'daily'), or only when a change occurs in the subscriber information. For example, CP1 (Cleansing Part1) may be an organization such as Korea Telephone Directory, Inc. 41, and the subscriber, telephone construction date, area code, telephone number, zip code, address and Provide your social security number. CP2 (Cleansing Part2) can be an institution such as credit card merchant 42, daily customer name, telephone construction date, area code, telephone number, postal code, address, business name (business) to the VAN server 30 Provide your name, type of business, business number and social security number. CP3 (Cleansing Part3) may be an institution such as the Korea Information Exchange (43), and provides the zip code, address, site number, building name, X / Y coordinate value, statutory copper code to the VAN server 30 every day. And CP4 (Cleansing Part4) may be an administrative agency system 44, such as the Ministry of Information and Communication, and if there is a change in postal code, address, branch number, administrative code, administrative name, etc., the changed subscriber information is stored in the VAN server 30. To provide.

As such, the latest subscriber information (cleaning information) provided from the information cleaning unit 40 together with the changed subscriber information provided from the information provider 10, the VAN server 30 is updated with the latest subscriber information. Make sure you keep the update information.

3 is a flowchart of an automatic subscriber information update procedure according to an embodiment of the present invention.

First, the VAN server 30 according to an embodiment of the present invention receives and stores the first subscriber information from the information provider 10. Thereafter, the VAN server 30 uses the changed subscriber information input through the information provider and the cleansing information input through the information cleaning unit 40 to update the first subscriber information with the latest updated subscriber information. To be maintained. The updated subscriber information may be periodically provided to the information using organization 50 at predetermined intervals. A detailed update procedure for subscriber information according to an embodiment of the present invention is as follows.

Referring to FIG. 3, when a subscriber first applies to change his / her personal information through the information provider 10 (step 301), the information provider 10 may request that the subscriber use another information user institution 50. Check whether there is a request of the subscriber information update service so that the subscriber's personal information can be automatically updated (step 302). If there is no application for the subscriber information update service, the process proceeds to step 301. If there is an application, the subscriber information utilization consent message is input (step 303). The subscriber information utilization agreement message may be used to restrict the request of the subscriber information update service and the information usage organization 50 to automatically update the subscriber information. Subsequently, the information provider 10 transmits the changed subscriber information to the VAN server 30 (step 304).

The changed subscriber information input from the information provider 10 is used to update the existing subscriber information (or the first subscriber information) together with the cleansing information input from the information cleaning unit 40. That is, the VAN server 10 maintains personal information about the subscriber in advance, and the subscriber information is updated with the latest subscriber information by using the changed subscriber information and cleaning information every predetermined time (for example, every day). Is updated (step 305). The updated subscriber information is subjected to a predetermined authentication process. Namely, among the updated subscriber information, for example, whether the social security number, address, building name, administrative name, etc. actually exist, and the like, the authentication is completed only if it can be properly updated (step 306).

When the authentication of the updated subscriber information is completed, it is determined whether the updated subscriber information matches the existing subscriber information (step 308). As a result of the determination in step 308, if the updated subscriber information matches the existing subscriber information, the procedure ends. On the other hand, if the updated subscriber information does not match the existing subscriber information, the existing subscriber information is changed to the updated subscriber information to maintain the latest subscriber information (step 309).

After the subscriber information is updated, the VAN server 30 selects the information using organization 50 and the transmission method for providing the updated information (step 310). In this case, the subscriber may selectively provide update information to a specific information user organization. In addition, the information transmitted from each of the information using institutions 50 may be constantly limited. That is, in order to effectively utilize subscriber information to be provided according to the characteristics of each information using organization 50, the transmission method of different types of information, form, format, etc. of the information may be used. Then, the updated subscriber information is transmitted to the information using organization 50 (step 311).

In this way, when the personal information of the subscriber is automatically updated to the specific information user organization 50, the result is notified so that the user can recognize it. As a notification method to the subscriber, an e-mail, an SMS message, or the like may be used (step 312).

4 is a flowchart illustrating an information transmission procedure through a communication network according to an embodiment of the present invention.

Referring to FIG. 4, a secure socket layer (SSL) is established between a VAN server 30 and an information provider 10, or a communication network 20 or 21, such as the Internet, between the VAN server 30 and an information user institution 50. The following describes an example of communication. In this case, the VAN server 30 serves as an SSL server as follows, the information provider 10 and the information using authority 50 serves as an SSL client.

First, the VAN server 10 transmits a hello request message (Hello Request) for proceeding the handshake protocol (Handshake Protocol) to the information provider 10 or the information user organization 50 (step 401). If the handshake protocol is already in progress, the information providing agency 10 or the information using organization 50 ignores the message.

Then, the information providing agency 10 or information using authority 50 transmits a client hello message (Client Hello) to the VAN server 30 (step 402).

After processing the client hello message, the VAN server 30 transmits a handshake failure alert message or a server hello message to the information provider 10 or the information user 50. . At this time, the VAN server 30, i) a random version generated by the SSL version of the server and the server, and ii) a cipher suit selected from the session identifier and the cipher suit sent by the client. Information about the compression method selected from the list is transmitted to the information providing organization 10 or the information using organization 50 (step 403).

If the VAN server 30 has its own public key certificate for server authentication, a message for server authentication to the VAN server 30 to the information provider 10 or the information user institution 50 (Server). Certificate or Server Key Exchange) (step 404). In this case, X.509 version 3 certificates are generally used, and the type of certificate or algorithm used for key exchange uses the one defined in the cipher suite of the server hello message.

Subsequently, the VAN server 30 allows the client to authenticate the server itself, and requests the client's certificate and sends a certificate request message to confirm whether the client is a trusted client. Or it transmits to the information using organization 50 (step 405). Steps 404 and 505 operate selectively, but through this, the client and server can mutually authenticate.

Thereafter, the VAN server 30 transmits a server hello done message (Server Hello done) informing that the information provider 10 or the information user institution 50 has sent all the messages to be sent from the server (step 406). . The reason why the server hello completion message is further sent is that a certificate request message (step 405) may be omitted, and the information provider 10 or the information user institution 50 may send the server hello completion message. It can be seen that there will be no further message transmission by receiving.

Subsequently, when the information providing agency 10 or the information using organization 50 requests a request for sending the client's certificate from the VAN server 30, the information providing agency 10 or the information using authority 50 transmits the client's own client certificate (step 407). If you do not have a certificate, send a No Certificate Alert.

Thereafter, the information providing agency 10 or the information using organization 50 generates 48-byte pre_master_secret information, which is arbitrary secret information used to generate the session key, and encrypts the pre_master_secret information according to the selected RSA public key algorithm. Send to the VAN server 30 (step 408).

In addition, the information provider institution 10 or information user agency 50 electronically signs the handshake message and transmits it to the server so that the server can easily verify the client's certificate transmitted by the request of the server, the server is included in the client's certificate Client verification is completed by verifying that the public key has been validated (step 409).

Subsequently, all messages transmitted in the future of the information providing agency 10 or the information using organization 50 transmit a message (Change Cipher Specs) indicating that the negotiated algorithm and key will be used (step 410). It then immediately generates a Finished message and sends it to the server, where the negotiated algorithm and key are first applied (step 411).

Subsequently, the VAN server 30 checks all messages transmitted by the client, that is, the information provider 10 or the information user 50, and then sends a Change Cipher Specs message to the information provider 10 or the information user. And transmits to step 50 (step 412). The service immediately generates and transmits a Finished message. The secure service is first applied to the Finished message using session information shared with each other, and the SSL handshake protocol step is terminated (step 413). Here, the client and the server may generate connection information (Server Write MAC Secret, Client Write MAC Secret, Server Write Key, Client Write Key) using the Master Secret before transmitting the Finish message.

In this case, when the SSL handshake is made, application data can be transmitted and received between the VAN server 30 and the information provider 10 or the information user 50 (step 401). That is, the information providing agency 10 may transmit the changed subscriber information to the VAN server 30, and the VAN server 30 may transmit the updated subscriber information to the information using organization 50.

5 is a diagram illustrating a transport packet formation procedure according to an embodiment of the present invention.

Referring to FIG. 5, a packet transmitted and received between the VAN server 30 and the information providing institution 10 or the information using authority 50 is formed as follows. First, the application data 510 is fragmented or combined into record protocol data (511 to 513). Each of the data 511 to 513 is compressed, and the compressed data 520 is encrypted by SEED / DES using a message authentication code (MAC) 530. The data 540 encrypted as described above may be transmitted and received through the Internet as a TCP packet 550.

The automatic subscriber information updating method according to the present invention can be embodied as computer readable codes on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also include those implemented in the form of carrier waves such as transmission over the Internet. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by those equivalent to the claims.

According to the present invention as described above, since the personal information of the subscriber can be automatically updated for various financial and public institutions on a plurality of Internet sites or offline, the subscriber does not have to repeatedly enter the changed personal information. The services of this registered agency can be provided smoothly.

In addition, according to the present invention, since the institutions providing credit transactions or various services can always maintain the latest subscriber information, it is possible to provide information services for subscribers without disruption, and waste time and money due to incorrect subscriber information. There is an advantage that can be reduced.
