Description

[DESCRIPTION]

[invention Title]

SYSTEM FOR REQUEST AND REGISTRATION FOR INTEGRATED RECEPTION OF EMAIL DOCUMENTS USING CLIENT-INTEGRATED ELECTRONIC MAILBOX

[Technical Field]

The present invention relates, in general, to a system for request for the integrated reception of online bills or notices, and, more particularly, to a system for request and registration for the integrated reception of a plurality of email documents using a client-integrated electronic mailbox, which allows a client to request the integrated reception of a plurality of email documents, such as online bills, from a plurality of institutions as desired by the client, using a client-integrated electronic mailbox on the basis of a certificate .

[Background Art]

Generally, emails destined for a client-integrated electronic mailbox are provided online to a user terminal as electronic information on the basis of personal information requested by a relevant institute. Of course, such emails destined for a client-integrated electronic mailbox may include online bills for charging fees incurred through the usage of service provided by a relevant institution, but may be collectively designated as various types of emails to be received, including personally managed documents which are provided to the client-integrated electronic mailbox according to the circumstances . As shown in FIG. 1, emails destined for the client- integrated electronic mailbox, for example, online bills, are processed through an integrated billing server 11, a bill presentment server 12, a consumer 13, a user Database (DB) 14, a bill DB 15, and a Simultaneous Peripheral Operation Online (SPOOL) DB, which are components required when an online bill processing system using a computer network is implemented.

Here, the integrated billing server 11 receives information about bills, which are to be sent, from respective business users, and stores the bill information in a suitable format. When the integrated billing server 11 transmits the bill information to the bill presentment server 12 using the SPOOL DB to enable the bills to be directly printed, the bill presentment server 12, having received the bill information from the integrated billing server 11, converts the bill information into a format suitable for the recipient thereof, and stores and manages various types of information related to the sending of bills . This method will be described below with reference to FIG. 2.

FIG. 2 is a diagram showing the integrated billing server in a conventional online bill processing method. As shown in FIG. 2, an input unit is a module for processing billing information input through a gateway and is configured to convert billing information, created in various formats, to a single identical metadata format and to support the bill presentment server so that the bill presentment server can process the total amount charged by each biller and other various types of related information, like the case of a consumer, through the management of the accounts of the user and the biller.

A record formatter functions to convert data having a metadata format into an internal record format so as to store the data in the SPOOL DB. A filter functions to classify bills into bills for the mass mail system of Korea Post Business Value, Information & Express (KOVIX) and bills for the bill presentment server, with reference to the bill sending method set forth in user registration information, and to convert billing data, which are to be sent to the KOVIX mass mail system, into the KOVIX mass mail format.

A search engine is a conditional DB search engine based on a Structured Query Language (SQL) and supports marketing by searching for consumers who satisfy conditions . The Electronic Bill Presentment and Payment (EBPP) Application Programming Interface (API) , which is configured to support a library used to create an EBPP application, supports a group of functions that will be used when the additional development of a library for subsequent high-quality service is required, without supporting applications for current consumer support centers. Further, the EBPP API supports both an EBPP DataBase Management System (DBMS) and a system management-based library, and thus executes APIs₇ provided by the system, with which it is used, and the DBMS.

The SPOOL DB refers to storage space for storing billing information before the billing information is transmitted to the bill presentment server. That is, the SPOOL DB is a storage space used before the billing information is transmitted to the KOVIX mass mail system, and is configured to automatically transmit billing information in the form of a combination of load/time conditions and to support both the real-time mode and the batch mode of data transmission.

First, a system manager can provide a module for EBPP service management (thick/thin consolidator or the like) , thus configuring the system according to the business model at the time of configuring the system, and can provide management functions required for respective cases . Second, the system manager provides a module for EBPP software management (backup of various types of DBs) , thus managing bill consolidator software itself, such as by monitoring errors occurring in the bill consolidator software itself and the performance of the software. Third, the system manager manages the load of a bill consolidator server system, thus monitoring and managing the entire situation of loads present in the bill consolidator hardware and software and networks on the basis of a Graphical User Interface (GUI) . As described above, the conventional online bill processing system is advantageous in that, since bills are not delivered by traditional postal services, the consumption of paper can be reduced, and costs incurred by- delivery and additional costs related to delivery failure can also be reduced, and in that consumers facing time constraints can be prevented from falling inevitably into arrears, through the realization of online payment for billing. However, this is merely a basic advantage between a single service provider and a person, so that, in the current situation, the person must input personal information for respective service providers and must be authorized to register the personal information when desiring to receive a plurality of bills or emails using a client-integrated electronic mailbox. Therefore, in the case in which personal information is provided to a plurality of service providers, it is inconvenient for a user to input such personal information, and, in addition, there is a serious concern about the leakage of personal information, and thus a fundamental revision to the system is required.

[Best Mode]

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings . FIG. 3 is a diagram showing a client-integrated certified electronic mailbox used to request and register the integrated reception of email documents using a client- integrated electronic mailbox according to the present invention. As shown in the drawing, the client-integrated certified ^' electronic mailbox is configured to receive insurance-related documents, real estate-related contracts, tax invoices, contents-certified documents, official documents, financial statements, and specification on transaction as well as various types of bills, settlement data, and fee notices, in an integrated manner from various credit card companies, insurance companies, communication service providers, banks, financial companies, real estate agents, medical institutions, public institutions, educational institutions, security insurance companies , etc .

The present invention is used to request and register the integrated reception of email documents in order to receive various types of documents and bills-, and performs a certification procedure on the basis of a digital signature created in connection with various credit card companies, communication service providers and public institutions . The certification procedure is performed based on a certificate for a client who uses the client-integrated certified electronic mailbox. Therefore, an integrated electronic mailbox, enabling certification with respective institutions to be performed in an integrated manner, is required in order to receive various types of documents .

The integrated electronic mailbox is used to request the reception of email documents from relevant institutions and the management of the email documents over the Internet by the terminal of each client . The client needs to initially input personal information requested by respective institutions only a single time. That is, the client inputs personal information according to a preset format through the integrated electronic mailbox, and attaches a certificate to the personal information so as to certify the personal information, thus receiving various types of documents, bills, etc . from arbitrary institutions .

Meanwhile, the integrated electronic mailbox is part of the business model proposed in the present invention, and may include a B2B model implemented for business clients and a B2C model and a G4C model implemented for personal clients . The B2B model, which is related to the internally managed documents in a business, for example, documents related to financial affairs, accounts, general affairs, personnel affairs, internal contracts, etc., may include content- certified documents, official documents, contracts, financial statements, appended papers for reports, specification on transaction, etc., which are required by law to be preserved. The B2B model may be utilized to issue bills, settlement data, fee notices, etc., which can increase the convenience of work. Further, the B2C model of the integrated electronic mailbox can be applied to the bills and notices provided through each individual's credit card payment amount, giro, charges for public service, communication fees, and four social insurance components .

FIG. 4 is a network configuration diagram of an integrated electronic mailbox unit according to the present invention.

First, an integrated electronic mailbox unit 401 according to the present invention is operated in association with a plurality of client terminals 403 and the management servers (not designated by reference numerals) of a plurality of document-sending institutions 405. The management servers are configured to send documents, provided by the databases (not designated by reference numerals) of respective institutions/ to a relevant client terminal 403. The databases are configured to manage the acceptance, registration, disposal and update of information about members who access the management servers and to retain the account information of email recipients .

The above-described integrated electronic mailbox unit 401 includes a member management server 409 for collecting and registering member information provided by each client terminal 403, a mail server 411 for providing information about the digital signature of each member to the document- sending institutions 405 and receiving documents, bills, and notices, provided by a relevant document-sending institution 405, together with the results of the registration of the member, on the basis of the digital signature thereof, a mailbox server 413 for retaining account information based on the establishment of cooperation with the document-sending institution 405, and receiving digital signature information required for the certification of a client, requested by the client terminal 403, and an operation server 407 for providing a one-click pattern web browser, required to request the reception of documents from various types of institutions, to the client terminal 403, requesting the sending of documents from any one. document-sending institution 405 selected through the web browser in an integrated manner, and transmitting the digital signature information for the certification of a relevant client, provided by the mailbox server 413, and the personal information, previously stored in the member management server 409, to the relevant document-sending institution 405 in order to request the sending of documents.

The operation server 407 preemptively prevents personal information from being leaked on the basis of the communication protocol set up with the document-sending institution 405 and the client terminal 403. Such a protocol may be one of a Simple Mail Transfer Protocol (SMTP) , a File

Transfer Protocol (FTP) , Telnet, a HyperText Transfer Protocol

(HTTP) , a Domain Name Service (DNS) protocol, a News Network Transfer Protocol (NNTP), etc. according to an embodiment of the present invention. Meanwhile, the certification server 415, not described above, is the operation server of a separate certification authority, and is operated in association with the mailbox server 413 of the integrated electronic mailbox unit 401. The representatives of the certification authority may include Korea Certification

Authority Central (KACA) , Korea Information Certificate

Authority (KICA) Inc., Korea securities computer corporation

(Koscom) , Korea Financial Telecommunications & Clearings Institute (KFTC) , National Information society Agency (NIA) Certification Authority, Korea Electronic Certification Authority (KECA) Inc., Korea Trade Net (KTNET), etc.

Therefore, when the web browser, required to request the reception of documents and provided by the operation server 407, receives a document reception request from the client terminals 403, the integrated electronic mailbox unit requests a digital signature required for certification from a relevant client, through the above-described certification authority. Further, the digital signature information for certification, provided by the relevant client terminal 403, is stored in the mailbox server 413. Further, the certification server 415 of the certification authority performs certification for the client, who requested the reception of documents, in association with the document-sending institution 405. The document-sending institution 405 performs the revision, registration, update or deletion of member information on the basis of the certification.

FIG. 5 shows an example of the web browser provided by the operation server 407, that is, the integrated electronic mailbox web browser used to request the integrated reception of documents or bills, which are sent by respective document- sending institutions .

The integrated electronic mailbox web browser includes a category selection key 507 formed on one side portion thereof to select information, such as a bill, a contract, a certificate, etc. for respective categories, an item selection button 505 provided to select all of a plurality of items belonging to a selected category when any one category is selected from the category selection key 507, an add button 511 provided to add an institution corresponding to an item, which is not set, and an information save button 509 provided to store and manage selected information, and further includes a folder display unit 503 provided to display folders corresponding to respective categories .

The above-described integrated electronic mailbox web browser is provided to the client terminal 403. For this operation, the client terminal 403 initially inputs personal information only a single time according to a predetermined procedure. The personal information is typical information required to verify whether the certificate of each person is authentic, and may include a name, a resident registration number, an address, a phone number, etc. When member subscription has been performed on the basis of personal information, the client terminal 403 receives the integrated electronic mailbox web browser, as shown in FIG. 5.

Therefore, the client receives documents, such as bills, contracts, and certificates, in , an integrated manner through the manipulation of the category selection key 507. Before this operation, the selection of items belonging to a given category must be conducted as a precondition. As illustrated in the 'bill' category, the selection of items is performed to select one or more items from among bills provided by public institutions, public services, public insurance providers, communication service providers, banks, credit card companies, insurance companies, and security corporations. For example, in the case of public institutions, detailed items, such as the National Tax Administration, the Office of Military Manpower Administration, self-governing bodies, administrative organizations, and police agencies, are arranged. When a document-sending institution is a communication service provider, detailed items, such as KT, SK Telink, SK Telecom, KTF, LGT, and Hanaro telecom, are arranged. Therefore, the client clicks a desired item among the detailed items using a mouse, thus completing the document reception request procedure requested by the client .

Of course, in addition to the institutions shown, other necessary institutions can be required according to the user' s environment. This operation can be performed by selecting an additional institution using the add button 511. The integrated electronic mailbox web browser can enable the integrated reception of documents to be requested using the integrated electronic mailbox proposed in the present invention, without individually accessing different institutions online. Hereinafter, the principal operation of the present invention will be described in detail below with reference to the attached drawings .

FIG. 6 is a flowchart showing operation in a B2B environment according to a first embodiment of the present invention. This shows the function of receiving and viewing documents between a plurality of businesses, and illustrates the operation performed between a single business client and a plurality of business members .

First, as shown in the drawing, at the first step, the business client must first endorse a contract to use a certified electronic document depository and the integrated electronic mailbox. This can be performed such that contracts for usage can be differently set according to the category of business operated by the business client, and such that contract conditions can be changed according to the type and number of documents that the business client desires to send. After contract conditions with the business client have been established, the business client registers a plurality of documents desired to be sent, for example, internally managed documents and externally sent documents, in the certified electronic document depository at the second step. The term 'internally managed documents' may be related to financial affairs, accounts, general affairs, personnel affairs, etc., and the term "externally sent documents' may include official documents, contracts, etc. When the registration of the documents in the certified electronic document depository has been completed, the viewing of the documents is possible.

The integrated electronic mailbox unit 401 sends an arbitrary document stored by the business client to a business member at the request of the business client. The notification of the document sending is provided to the relevant client terminal 403 via the Internet. Here, the business member can view the corresponding document through the integrated electronic mailbox unit 401, but this viewing is possible only after subscription to the integrated electronic mailbox unit 401 as a member has been conducted as a precondition. That is, the business member that has subscribed as a member can view the document sent by the relevant business client on the basis of a certification procedure that uses the certificate of the business member together with the ID and the password thereof.

That is, the member server 409 receives the member's personal information provided by the client terminal 403, determines whether the business member is an authentic member, and notifies the operation server 407 of the results of the determination. The operation server 407 requests the certification of the relevant business member on the basis of the results of the determination. The client terminal 403 goes through a predetermined certification provision procedure, and the mailbox server 413 verifies such certification. The mailbox server 413 verifies the certification of the business member in association with the certification server 415, and notifies the operation server 407 of the results of the verification.

When it is determined by the operation server 407 that the currently accessing business member is a previously registered member, the mail server 411 transmits information about the document of the relevant business client, previously registered in the certified electronic document depository, to the client terminal 403 of the business member. Therefore, the business member views the document sent by the relevant business client. Here, as a precondition, the business member must subscribe to the integrated electronic mailbox 401 as a member, but a business member who has not subscribed to the integrated electronic mailbox 401 as a member can also view the document on the basis of an admission key required to view a deposited document. Such an admission key can be transmitted through the personal email or mobile phone of a business user who has not subscribed to the integrated electronic mailbox as a member, and the inquiry about and viewing of documents deposited in the certified electronic document depository can be performed on the basis of the admission key.

FIG. 7 is a flowchart showing operation performed in a B2C environment according to a second embodiment of the present invention. This shows the function in which persons receive and view documents as part of the relationship between arbitrary businesses and persons . In this procedure or the above-described procedure, the certified electronic document depository may be each business client's own document deposit server, or may be a certified document deposit agency, which is the component of a network for guaranteeing the originality of the documents sent by the business client .

At the first step of this flowchart, a personal member accesses the integrated electronic mailbox 401 via the client terminal 403, and subscribes to the integrated electronic mailbox 401 through a defined procedure. The procedure for personal member subscription can be performed in such a way that a digital signature is attached to a certificate as a personal information input procedure or a personal authentication procedure. Of course, the personal member subscription procedure can vary according to the method in which the system is implemented.

When the member subscription of the client terminal 403 has been completed, the operation server 407 provides the integrated electronic mailbox web browser to the client terminal 403 at the first step. This corresponds to the web screen of the client terminal 403, as shown in FIG. 5. The personal member request the reception of one or more documents using the plurality of category selection keys 507 and the item selection buttons 505 corresponding to respective categories at the second step. Here, the term 'documents' means bills or contracts sent by public institutions, public services, communication service providers, banks, insurance companies, etc .

That is, the personal member requests the reception of documents that are sent by a plurality of document-sending institutions 405 in an integrated manner. The document- sending institutions 405 must register relevant documents in advance in their own document depositories, or the certified electronic document depository. Of course, respective document-sending institutions 405 must enter into an agreement with the integrated electronic mailbox unit 401 on cooperation as a precondition. Therefore, the mailbox server 413 retains information about online communication with respective document-sending institutions 405. Thereafter, a plurality of reception document items selected through the integrated electronic mailbox web browser is registered and managed in the member management server 409, and includes digital signature information for the certification of the personal member. The mailbox server 413 verifies the digital signature for the certification of the personal member in association with the certification server 415, and provides the results of verification to the operation server 407. After the completion of the certification of the personal member, the operation server 407 collects and combines both information about institutions from which documents, registered in the member management server 409, are desired to be received, that is, the institutions from which the personal member has requested the integrated reception of documents through the integrated electronic mailbox web browser, and information about corresponding document items to be received. Further, the operation server 407 collects and combines online account information about the institutions that have been arbitrarily selected by the personal member and are registered in the mailbox server 413. The operation server 407 sends a document reception request to the institutions so that the client terminal 403 can receive documents from the institutions . This is performed in such a way as to sequentially send reception document items, together with a certificate that carries the digital signature of the personal member, to a plurality of institutions, that is, the selected document-sending institutions 405. The relevant document- sending institutions 405 verify the certificate in association with the certification server 415. After the verification by the document-sending institution 405 has been completed, the business client sends documents desired by the personal member to be received, that is, documents, such as contracts, certificates, guarantees, certificates of inscription, and licenses, as well as notices/bills for credit cards, electric charges, gas charges, and communication fees, to the integrated electronic mailbox unit 401 via the mail server 411 at the third step. The operation server 407 sends a plurality of documents, received from the mail server 411 to the client terminal 403, and the personal member receives various types of documents from respective institutions, which are received through the client terminal 403 in an integrated manner.

Meanwhile, in this embodiment, the documents sent by the document-sending institutions 405 are directly sent from a relevant institution, that is, the business client, to the integrated electronic mailbox 401, but it is apparent that the documents can alternatively be provided to the integrated electronic mailbox 401 via the certified electronic document depository, as described above. This procedure can be implemented as a procedure for guaranteeing the originality of sent documents, or a personal information guaranteeing procedure for preventing information about personal members from being provided to relevant institutions .

[industrial Applicability] As described above, the present invention is advantageous in that the client-integrated electronic mailbox, proposed in the present invention, enables a complicated procedure, for authenticating members and requesting the reception of documents from respective institutions in order to receive online documents, to be performed only a single time, so that the usage of service can be simplified, undesirable effects attributable to the leakage and illicit use of personal information can be fundamentally eliminated, and reliable service can be realized, thus increasing the usefulness of the service and greatly improving industrial applicability.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims .
