The present invention relates to a certified electronic document storage system and a service providing method thereof. More specifically, after registering and storing electronic documents (image documents, structured documents, and atypical documents), the electronic documents storage service, sending and receiving relay services, certificate issuance services, etc. The present invention relates to a technology capable of providing a portal service for electronic document storage.

It is estimated that Korean companies and financial institutions spend more than 27 trillion won per year on the distribution and storage of various documents or documents, and the reality is that the utilization of archived documents such as search and reference is difficult. For example, 1.5 billion copies of credit card sales slips are issued annually, which is estimated to cost about 120 billion won to be collected by credit card companies and stored in document storage. In addition, there is always a risk of loss or damage during the storage of the documents. In addition, there is an inefficiency in finding and referring to the relevant credit card sales documents in case of dispute.

Similar examples can be found in most companies. In fact, most of the representative companies in Korea, such as Samsung Electronics and Hyundai Motor Company, have document warehouses of more than 1,000 pyeong. Paper documents stored in these document warehouses are stored for 5 to 10 years including tax data, and there is a risk of loss or damage of documents such as fire.

In addition, the amount of paper documents continues to increase as business activities expand, and it becomes difficult to sort, search, and reference them over time due to the reorganization and the movement of personnel. Despite these inputs of time, cost and effort, the ratio used for dispute resolution and data submission is very low.

If the paper document is replaced with an electronic document, the document storage required for storing the paper document can be gradually reduced, and the search and utilization can be performed online, thereby greatly saving time and money.

Therefore, the use of electronic documents is one of the key factors in enhancing competitiveness by enhancing the efficiency and speed of business processes. In addition, the electronic documents can be stored remotely using a backup system to prevent the risk of loss or damage due to fire or flood.

The present invention is to solve the above problems, the object of the present invention is to register and store electronic documents (image documents, structured documents, unstructured documents) electronic documents to customers, such as enterprises, organizations through a certified electronic document storage server By providing portal services for storing certified electronic documents such as storage, transmission / reception, certificate issuance, etc., it is possible to reduce the cost of storing electronic documents, and to improve the efficiency and speed of work processing.

At this time, the DB server includes a medium information DB for storing long-term storage medium information data for electronic document properties and classification, content certificate issuance, certificate issuance, etc. of each financial institution, private enterprise, public institutions; An original / certificate storage DB for storing information data about the original, converted document, certificate, etc. of the electronic document; Meta-information DB for storing the system information automatically generated by the index information, classification information, user information, etc. for managing the electronic document, and meta information data for automatic extraction and handwriting input data by recognition for indexing and searching; Characterized in that configured to interlock.

In addition, according to the present invention, in conjunction with the electronic document conversion server, the electronic document registration / storage / conversion for the purpose of storage until the generated and discarded, electronic document search / reading, electronic document issuance, electronic A first step of providing an electronic document storage service for a document transfer / disposal process; Distribute the electronic document to the designated recipient for the electronic document submitted for distribution or for distribution only, and check the transmission and reception of the electronic document, status / history management, forgery / deny prevention, linkage with other storage servers, and distribution A second step of providing a transmission / reception relay service for a process; And a third step of providing a certificate issuance service for a process of performing a task of issuing / inquiring / revocation / verification of a certificate for the electronic document and generating and processing a certificate request message and a configuration of a certificate in a specified format. ; It provides a method for providing a certified electronic document storage service comprising a.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

Prior to the description of the present invention, a detailed description of known functions or configurations related to the present invention will be omitted if it is determined that the gist of the present invention may be unnecessarily obscured.

1 is an overall configuration diagram of a certified electronic document storage system according to the present invention, Figure 2 is a detailed configuration diagram of the certified electronic document storage server shown in FIG.

As shown in Figure 1, the authorized electronic document storage system according to the present invention is a user terminal 100 that is linked with the scanner device 50; Network 200; Certified electronic document storage server 300; A DB server 400 interworking with the medium information DB 410 for long-term storage, the original / certificate information DB 420, and the meta information DB 430; Public certification authority server 500; And a billing management server (600).

The user terminal 100 may be a financial institution such as a financial settlement agency, the Bank of Korea, domestic or foreign banks; Private companies such as mobile carriers, construction companies, manufacturing / services, distribution / logistics, etc .; Other public institutions; as a communication terminal device for the use of certified electronic document storage service, a computer (PC), a notebook computer, a mobile communication terminal (mobile phone), and a personal digital assistant (PDA) are applied. The scanner device 50 is a device for converting various paper documents into electronic documents, and excludes a digital camera, a hand scanner, and the like.

In this case, in the case of a paper document, the user terminal 100 includes a large-capacity document of a financial institution (a variety of financial documents), a private company (internal corporate document, external document, inter-company transaction document), or a public institution (civil document). By scanning the batch using the high-speed scanner device 50 and performing the recognition and correction work, the paper document is imaged (digitized) to be registered and stored. Of course, among the types of electronic documents, the structured document and the unstructured document can recognize the document itself as an electronic document, thereby eliminating scanning operations such as paper documents.

The network 200 represents a wired or wireless communication network for establishing a communication interface to enable data communication between the user terminal 100 and the official electronic document storage server 300.

Certified electronic document storage server 300 is to ensure the originality of the electronic document (image document, structured document, unstructured document) legally while keeping / storing the electronic document and using the stored original document, and transferred to another storage server. Basically, it provides management services for the life cycle of electronic documents, up to disposal. In this case, the electronic document in the present invention refers to an image document, a structured document, and an unstructured document, which are created in an electronic form by an information processing system such as a computer and transmitted or stored and certified by an authorized certification authority.
