Description

FIELD OF THE INVENTION [0001] The present invention relates to a system and a method for searching and providing an original document image file,

The present invention relates to a system and method for searching and providing a file, and more particularly, to a system and method for searching and providing an original document image file.

In a government office, a securities company, or a bank, all documents such as contract documents, personal information documents, and application documents are stored. These documents are scanned by a scanner and stored as image files . In addition to written documents, fax documents and e-mails are kept as scanned image files for personal information documents.

Since the amount of documents is so large and constantly accumulated, it is easily stored as a scanned image file since it is not easy to keep it as a document file.

However, when a personal information document or a document to be searched later is to be searched, the character of the image file can not be read so that the search level is lowered and the usability thereof is very low.

When storing a scanned image file, only the basic information such as the type of the scanned image file, the title, the date, and related personal information are stored together. Therefore, the scanned image file can be searched only within the range that can be searched through such basic information Only.

Since the scanned image file also contains various contents, there is a limitation in performing a specific search in a wide range, for example, collecting real estate contract documents or searching for a real estate contract document of a specific individual. For example, although you can specifically search for Person A's September 23, 2016 dossier, a more diverse and broader search based on the text is not possible.

Of course, scan image files may be recognized as OCR (optical character reader) and stored as document files such as PDF. However, personal information and security related contents contained in these documents may be illegally leaked through document files or exposed by hacking The risk is very high. Most of these documents contain personal information.

In addition, in the case of separately storing each document file such as PDF, it takes a considerable time to open and read each file to check the contents of the document file, and there is a problem that the convenience of access is very low.

Accordingly, it is possible to solve the problem that the inconvenience of searching according to the existing scan image file method and the problem that the searchable level itself is lowered, and the security risk or convenience of access which is caused when the document file is stored is lowered There is a demand.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a system for searching and providing an original document image file according to an embodiment of the present invention.

Referring to FIG. 1, an original document image file searching and providing system 100 according to an embodiment of the present invention includes an original document image file database 110, an optical character reader (OCR) recognition / metadata metadata extraction module 120, an XML conversion module 130, an XML document file database 140, a tag extraction module 150, an XML document search module 160, an original document image file provision module 170, . ≪ / RTI >

The system 100 for searching and providing an original document image file is configured to separately construct an original document image file database 110 and an XML document file database 140. The system 100 includes two operations, Can be implemented.

In particular, there is no fear that the contents of the text or the personal information contained in the text will be leaked, and each document is implemented as an XML document, so it is very convenient and easy to search Is high.

Hereinafter, the detailed configuration will be described.

The original document image file database 110 is a configuration in which an original document image file is stored in advance.

The original document image file database 110 is a configuration for scanning original documents including personal information of a securities company, a bank, a government office, a court, a hospital, and the like and storing them as image files. It is a database already built in various uses.

The OCR recognition module 120 may be configured to perform an optical character reader (OCR) recognition by scanning an original document image file stored in the original document image file database 110. [

The OCR recognition / metadata extraction module 120 can be configured to recognize characters of an original document image file and convert them into readable character codes such as ASCII codes.

In addition, the OCR recognition / metadata extraction module 120 may be configured to extract metadata representing a format of an original document image file.

The OCR recognition / metadata extraction module 120 may be configured to extract metadata for replacing an original document such as data, schema, contents, links, etc. in an XML format.

Meanwhile, the tag extraction module 150 may be configured to automatically extract a tag from the contents of the original document image file recognized by the OCR recognition / metadata extraction module 120.

The tags can be defined by predetermined algorithms and can be determined according to the characteristics of the documents. The tag can be automatically extracted from the contents of the document. In the case of a bank, the title such as an account opening agreement or a cash card application can be automatically designated as a contract month, a name, and the like. In addition, the tag may be composed of predetermined keywords such as a contract, an opening, an account, a card, a loan, a credit loan, a security, and the like.

These tags can be used to perform searches on vast amounts of document content. The tag can also be used for searching for big data analysis.

The XML conversion module 130 may be configured to convert the original document data of the original document image file recognized by the OCR recognition / metadata extraction module 120 into an XML document using the metadata. An XML document is implemented in a format that is configured to facilitate retrieval as well as accessing its contents. Multiple XML documents can be interlinked and configured to enable full content retrieval from a remote location.

The XML document converted by the XML conversion module 130 may be stored in the XML document file database 160. [ The XML document stored in the XML conversion module 130 may be stored in a one-to-one correspondence with the original document image file already stored in the original document image file database 110. [

Meanwhile, the XML document search module 160 may be configured to receive a search request from the user terminal 10 at a remote location.

The XML document retrieval module 160 may be configured to retrieve the original text data requested to be retrieved by the user terminal 10 in the XML document stored in the XML document file database 140. [

The original document image file providing module 170 does not provide the XML document retrieved from the XML document retrieving module 160 directly to the user terminal 10 but directly outputs the original document image file corresponding to the retrieved XML document to the original document image file DB (110) and provide it to the user terminal (10).

The XML document search module 160 searches the contents of the text itself and does not provide the retrieved contents to the user terminal 10 as it is. This is because if the contents of the body of the XML document can be read or read as character code, the access is restricted because of the risk of leakage of personal information or important security information.

The XML document retrieving module 170 may be configured to retrieve the original document data requested to be retrieved by the user terminal 10 by using the metadata extracted from the tag extracting module 150. [

For example, the contents of an XML document can be retrieved by using search terms such as X, XX, contract, and loan. Multiple XML documents containing these search terms can be retrieved.

On the other hand, the retrieval method using metadata can be utilized for big data analysis. Since the content of the text is not provided in the form of a readable character code even in the analysis of the big data, the XML document search module 160 searches the search result while limiting the exposure of the contents of the text, Results can be provided. For example, the search results such as the number of contracts for mortgage loans in 2016, the number of cases by region, and age can be culled, and the Big Data Analysis Module (not shown) can perform big data analysis using these search results. The XML document retrieval module 160 provides only the number of hits, such as the number of contracts, the number of regions, and the age, without exporting the personal information, so that the big data analysis can be performed without exposing personal information or security information can do. Searchers or big data analysts who search for them or search for big data can do search or big data analysis without exposing personal information or security information.

That is, the content of the XML document itself is configured not to leak out of the XML document file database 140. It can be seen that only an identifier indicating the retrieval result (retrieval result, number of hits, etc.) or an original document image file corresponding to the retrieved XML document is provided outside the XML document file database 140.

2 is a flowchart illustrating a method of searching for and providing an original document image file according to an embodiment of the present invention.

Referring to FIG. 2, an optical character reader (OCR) recognition module 120 scans an original document image file stored in advance in an original document image file database 110 to perform OCR recognition, Metadata is extracted (S101).

Next, the XML conversion module 130 converts the original document data of the original document image file in which the OCR recognition is performed by the OCR recognition module 120 into the XML document using the extracted metadata, (S102).

Next, the tag extraction module 150 automatically extracts a tag for searching the contents of the original document image file in which OCR recognition is performed by the OCR recognition / metadata extraction module 120 (S103 ).

Next, the XML document search module 160 searches the XML document stored in the XML document file database 140 for the text data to be searched by the user terminal (S104).

At this time, the XML document retrieving module 160 may retrieve the original document data that is requested to be retrieved by the user terminal 10 by using the tag extracted from the tag extracting module 150.

Next, the original document image file providing module 170 searches the original document image file database 110 for the original document image file corresponding to the original text data retrieved from the XML document retrieval module 160, and provides the original document image file to the user terminal 10 (S105).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims. There will be.

110: Original document image file database
120: OCR recognition / metadata extraction module
