Description

Document authentication method and document authentication system with enhanced authentication function by notification of inquiry history

The present invention relates to a document authentication method and a document authentication system, in addition to being able to check whether a document is authentic or not based on document authentication information registered by a document issuer, the document issuer can be notified of the inquiry history of a document viewer, thereby providing a document authentication function. It relates to a more enhanced document authentication method and document authentication system.

Various documents such as public documents issued by public institutions, private documents used for private business between individuals, commercial documents that travel between individuals or companies for profit purposes, and various documents such as slips used in a certain format to improve efficient business efficiency are available online and offline. It is actively published and distributed on the website.

Documents issued by public institutions are relatively easy to determine whether the documents are authentic, but documents issued by individuals or corporations can only be identified with a seal stamp of the document issuer (or document issuing company). It is difficult to accurately determine whether it is authentic or not.

In order to accurately determine the authenticity of a document issued by an individual or company, it is desirable to contact the document issuer directly to inquire about the authenticity of the document, but if the document issuer's contact information is not listed in the document, the document issuer It is also difficult to get in direct contact with.

Furthermore, if the document issuer is a company, it is not easy to find out who the person in charge of the document is. In general, only the company name is stated in the document, so it is difficult to accurately identify the department in charge and the person in charge as the document, and it is more difficult to determine the authenticity of the document when the person in charge is changed or absent.

Also, the person who received the document has no way of knowing whether the document was issued only to him or her or to another third party.

Also, in the case of document publishers, once a document is published, there is no way to verify who the document was distributed to, and even if the document is being abused, there is no way to verify this.

Korean Patent Laid-Open Publication No. 10-2002-0037651 (published on February 22, 2001) "How to issue a document in communication and provide a service for verifying the authenticity of the document" is to issue a document by fax, remote printer, e-mail, etc. And, if a third party enters the receipt time and document number indicated on the document for the issued document requested offline, the seal, signature, transmission time, and document issuer name of the issued document are displayed, and the third party displays the requested document and the document number. By comparing the contents, the document is checked for authenticity.

Republic of Korea Patent Publication No. 10-2009-0123555 (published on February 2, 2009) "On-line issuance confirmation system and method for issuing documents" refers to a document issued when a printer module installed in a printer that issues a document prints an issued document. The issuance information and authentication information are generated and sent to the issuance verification server, and the issuance verification server receives the authentication information of the issued document online and authenticates it, thereby presenting a technology that shows the issuance information of the issued document.

In addition, Korean Patent Registration No. 10-0405828 (registered on November 14, 2003) "An apparatus and method for producing a document capable of preventing forgery and alteration, and an apparatus and method for authenticating the document" refers to documents produced online and offline. It is to prevent forgery or forgery during online or offline distribution, or to check whether or not the barcode itself is forged or altered, and creates a barcode and a watermark based on the information included in the document, and The barcode and watermark are combined, the combined barcode and watermark are inserted into the document to produce a document.When authenticating the produced document, the document is detected and the barcode inserted in the document is extracted, and the extracted barcode The process of comparing the included information with the information contained in the document, and also the process of detecting the document and extracting the watermark inserted in the document, and comparing the information contained in the extracted watermark with the information contained in the document. It goes through.

In addition, Republic of Korea Patent Registration No. 10-1039390 (registered on May 31, 2011) "Method and device for verifying the authenticity of issued documents using bar codes" is to recognize the address of the verification server from the barcode printed on the issued document and verify through the recognized address. A technology that automatically connects to the server and receives a copy file of the issued document from the verification server to verify the authenticity is presented.

Such conventional techniques focus on verifying the authenticity of the document itself. However, it is very cumbersome for the document viewer to directly compare the real document and the certified document.

In addition, if the real document and the certified document are completely different, it is easy to know whether the document is authentic, but if a small part of the real document is altered, it is very difficult to compare it with the certified document and find the altered part directly. It's work.

The present invention has been devised to solve the problems of the prior art as described above, and has been proposed to more easily confirm the authenticity of a document.

In particular, the present invention makes it possible to easily check whether the document is authentic or forgery by using document authentication information registered by the document issuer, as well as easily determine whether the document is authentic or forgery by using the inquiry record of the document viewer.

As shown in FIG. 1, the system includes a document authentication server 100, a plurality of first terminals 10 and a plurality of second terminals connected to the document authentication server 100 through a wireless communication network or a wired communication network. It consists of (20).

The plurality of first terminals 10 are terminals each provided by a plurality of document issuers.

The plurality of second terminals 20 are terminals each provided by a plurality of document viewers.

The first and

second terminals

10 and 20 are also referred to as'devices' and refer to all devices that can access the Internet, such as PCs, mobile phones, and tablets.

When the first and

second terminals

10 and 20 are PCs, programs necessary for the present invention are executed through a client program or web connection, and when the first and

second terminals

10 and 20 are portable devices such as mobile phones and tablets, The program required for the present invention is executed by the application of the device.

As shown in FIG. 2, the document authentication server 100 includes a connection management unit 110, a member information management unit 120, a document authentication information management unit 140, an authentication document image generation unit 150, and a document authentication information inquiry. It consists of a unit 170, an inquiry history management unit 180, an inquiry history notification unit 190, and the like.

The member information management unit 120, when a person who has not yet registered as a member, that is, a member subject to new registration attempts to access the first terminal 10 or the second terminal 20, the personal information regarding the new member first. It is transmitted from the terminal 10 or the second terminal 20 and registers a member ID and personal information about the member in the member information storage unit 121.

Personal information about the member includes the member's name, the member's organization name, e-mail address, contact information, the location of the terminal (device) at the time of signing up, information of the terminal (device) at the time of signing up, and information on authenticated mobile phones.

You can use the member's e-mail address as a member ID or register a separate member ID.

Member information of the member information storage unit 121 is encrypted and stored.

In this embodiment, membership registration is performed by verifying the member's email address as a member ID.

Since the configuration of the member information management unit 120 and the member information storage unit 121 is very general, a detailed description thereof will be omitted.

The connection management unit 110, when the first terminal 10 or the second terminal 20 requests access while inputting a member ID (that is, when attempting to log in to a member), the member ID is stored in the member information storage unit ( 121) is determined to allow access to the first terminal 10 or the second terminal 20 in the case of a registered member ID.

In this embodiment, the connection management unit 110 executes the document authentication information management unit 140 when the program driven in the first and

second terminals

10 and 20 requesting access is a PC version or a web version, and requests access. When the program of the first and

That is, according to the type of the program running in the

terminals

10 and 20, whether the corresponding terminal is the first terminal 10 or the second terminal 20, and accordingly, the document authentication information management unit 140 or the document authentication information inquiry unit 170 is automatically selected and executed.

Of course, a program running in the

terminals

10 and 20 may provide an option of selecting the document authentication information management unit 140 or the document authentication information inquiry unit 170.

A case where the terminal connected to the connection management unit 110 is the first terminal 10 of the document issuer will be described.

Step of allowing connection to the first terminal

The first terminal connection permission step of allowing the connection management unit 10 to access the first terminal 10 is executed.

Steps to save document authentication information

When the first terminal 10 accesses the document authentication server 100, the document authentication information management unit 140 is executed, and the first terminal 10 is provided with an upload service screen of a document to be authenticated as shown in FIG. 4.

When a document issuer uploads a document file or image file to be authenticated on a corresponding service screen, the document file or image file is transmitted to the document authentication information management unit 140.

These document files or image files are collectively referred to as a'document image'.

If the document to be authenticated is an electronic document such as PDF, the electronic document such as PDF is a document image, which is directly transmitted to the document authentication information management unit 140.

If the document to be authenticated is a real document, the document is made into a document image (image file or electronic document file, etc.) using a scanner or a camera, and then transmitted to the document authentication information management unit 140.

After the document image is transmitted, the document authentication information management unit 140 stores access information of the first terminal and document authentication information including the transmitted document image in the document authentication information storage unit 141.

That is, the document authentication information includes at least access information of the first terminal and a document image.

Here, the connection information of the first terminal refers to information that can be obtained by accessing the first terminal without having to input separate data from the document issuer, and this includes the personal information of the document issuer, the date of issue of the document, and the location of the document issue.

The document issuer's personal information is the member's personal information obtained from the member ID of the member who accessed the member (name of the member, the member's organization name, email address, contact information, terminal (device) location at the time of membership registration, terminal (device) information at the time of membership registration, and authentication. Mobile phone information, etc.).

In practice, the document issuer personal information stored in the document authentication information storage unit 141 is to be stored only by the member ID, and when document authentication information is inquired, the member ID of the document authentication information is referred to and registered in the member information management unit 120 It is advisable to search together the member information.

The document issuance date and time is the date and time (date and time) at which the document image was transmitted.

The document issuing location is the location of the first terminal.

The document authentication information management unit 140 may additionally receive information on the document validity period and the number of copies of the document issued from the first terminal 10 and store the information by including it in the document authentication information.

The information on the document validity period is information on how long the document is valid, and the document authentication information after the document validity period is not inquired by the document viewer. This allows the document issuer to control the indiscriminate outflow of documents.

The information on the number of copies of the document issuance is information on how many copies of the document have been issued, and by this, the viewer of the document can check whether the document is normally distributed by comparing the information on the number of copies of the document and the inquiry history information. .

If the number of inquiry history to be described later is 1 even though the number of document issuance is 100, the reliability of the document will be low, and if the number of inquiry history to be described later is 5 even though the number of document issuance is 1, the document is likely to be forged. I can judge.

Meanwhile, the document authentication information may include information on the number of inquiry history. The number of inquiry history is information on how many times the document authentication information has been searched, and means the number of inquiry history information for the document authentication information stored in the inquiry history information to be described later.

Accordingly, the document authentication information may consist of a document issuer's personal information, document issuance date and time, document issuance location, document validity period, document issuance number, number of inquiry history, document image, and the like.

On the other hand, the document issuer may request to restrict inquiries for some of the document authentication information, and the information subject to such inquiry restrictions is not inquired by the document viewer, even if it is document authentication information.

It is preferable that the document authentication information stored in the document authentication information storage unit 141 is stored in an encrypted form, and the document authentication information in the encrypted form is transferred to the second terminal 20 by the document authentication information inquiry unit 170. When document authentication information is transmitted, it is decoded and transmitted.

This encryption and decryption method follows the following method.

The original file is encrypted after extracting the unique hash of the file. The body of the encrypted file (BODY) is stored in the database (DB) in a BLOB method. This is a structure that cannot be recovered without a hash key value even if the DB value is retrieved by malicious hacking. The unique hash value of the file is separately stored in the database along with the location information where the body of the file is stored. When calling (ie, restoring) the original file, the original file body value is retrieved by referring to the location value stored with the hash, and the hash value is combined to restore the original file.

This encryption/decryption process is applied not only to document authentication information, but also to storage of member information and inquiry history information.

The document authentication information storage unit 141 may be divided into a document image storage unit in which a document image is stored, and a database storage unit in which the remaining information data is stored in a database format.

The document authentication information stored in the document authentication information storage unit 141 is stored in an encrypted form so that it cannot be viewed unless there is a recognition mark (specifically, a QR code) to be described later. Therefore, even if the administrator of the document authentication server 100 does not store a separate QR code in the document authentication server 100, the document authentication information stored in the document authentication information storage unit 141 cannot be arbitrarily inquired.

Steps for sending the certified document image

The authentication document image generation unit 150 generates a recognition mark including inquiry key information for the document authentication information, and generates an authentication document image in which the generated recognition mark is inserted into the document image, and the first terminal ( 10) Send the authentication document image.

The recognition mark may be a mark that can be visually recognized by taking a picture or the like, and the recognition mark may be a one-dimensional barcode, a two-dimensional barcode, or a quick response (QR) code.

The identification mark includes inquiry key information, and the inquiry key information is key information for inquiring the document authentication information.

In particular, the recognition mark in this embodiment is a key value for inquiring encrypted and stored document authentication information and related member information and inquiry history information. If there is no such recognition mark, document authentication information, member information, and inquiry history information Cannot search.

In this embodiment, the authentication document image generating unit 150 generates and stores an electronic document in PDF format by generating a QR code accessible to the document authentication information and inserting the QR code into the document image.

In this embodiment, not only the QR code is inserted into the document image, but also the authentication mark is inserted.

5 is an example of a document image (original document) and an authentication document image (with QR code and authentication mark inserted).

The QR code 21 and the authentication mark 22 are inserted into the document image 10 of the original document to generate the authentication document image 20.

Depending on the embodiment, the authentication document image may be additionally stored in the document authentication information storage unit 141 in an encrypted form. However, in any case, only the first terminal 10 of the document issuer can download the image of the authentication document.

6 is an example of a screen for downloading an authentication document image displayed on the first terminal 10.

The first terminal 10 of the document issuer downloads the image of the authentication document including the QR code, and after the download is received, the document issuer issues it.

That is, an image of an authentication document in PDF format is output to a printer connected to the first terminal 10 and directly transmitted to the document viewer or distributed to the document viewer in the form of an electronic document, that is, in the form of a PDF email.

This completes the document issuer's document issuance.

The following describes the document search process by the document viewer.

That is, when the terminal connected to the connection management unit 110 is the second terminal 20 of the document viewer.

Steps to allow access to the second terminal

The second terminal connection permission step of allowing the connection management unit 10 to access the second terminal 20 is executed.

Steps to look up document authentication information

When the second terminal 20 accesses the document authentication server 100, the document authentication information inquiry unit 170 is executed, and the second terminal 20 starts with a screen for recognizing (taking) a QR code.

That is, a camera application built into the second terminal 20 is executed, a QR code reading service on the web is executed, or a QR code is transmitted to the second terminal 20 using a camera or scanner connected to the second terminal 20. Can be entered.

Accordingly, the document inquiry person photographs or scans the QR code printed on the document, and the second terminal 20 transmits the inquiry key information of the QR code or the QR code itself to the document authentication information inquiry unit 170.

The document authentication information inquiry unit 170 receives information on a recognition mark (QR code) or inquiry key information included in the recognition mark, uses the inquiry key information to inquire the document authentication information, and retrieves the searched document authentication information. It transmits to the second terminal 20.

At this time, the document authentication information is stored in the document authentication information storage unit 141 in an encrypted form, and the document authentication information is decrypted using the inquiry key information included in the QR code and transmitted to the second terminal 20. desirable.

As mentioned above, the document authentication information to be inquired includes the document issuer's personal information, the document issuance date and time, the document issuance location, the document validity period, the number of documents issued, and the document image.

Among the document authentication information to be searched, the document image corresponds to the original document.

On the other hand, information that has been restricted by the document issuer is not searched by the document viewer. In other words, the document viewer can search only the information that the document publisher has allowed to search.

On the other hand, among the document authentication information for which the document validity period has been set, the document authentication information whose document validity period has elapsed is not searched by the document viewer, and the second terminal 20 "is a document whose validity period has passed". Is displayed.

Meanwhile, the document authentication information inquiry unit 170 stores not only document authentication information, but also inquiry history information (stored in the inquiry history storage unit 181 to be described later) for the document authentication information in the second terminal 20. Send together.

The inquiry history information for the document authentication information refers to the access information of the second terminal that inquired the document authentication information.

The access information of the second terminal as the inquiry history information refers to information that can be obtained by accessing the second terminal without the need for separate data input by the document viewer, and this includes the personal information of the document viewer, the date and time of the document inquiry, and the location of the document inquiry. .

As a result, the document viewer can search not only the document authentication information registered by the document issuer, but also the document inquiry records of other document viewers.

In this way, after the document authentication information is inquired by the second terminal 20, the inquiry history management unit 180 and the inquiry history notification unit 190 are executed.

Steps to save inquiry history

The inquiry history management unit 180 additionally stores access information of the second terminal 20 that has inquired for the document authentication information as inquiry history information for the document authentication information in the inquiry history storage unit 181.

In addition, whenever search history information is added to the document authentication information, the number of search history that is part of the document authentication information increases.

If the document authentication information is inquired 10 times, 10 inquiry history information is stored for the document authentication information, and the number of inquiry history of the document authentication information is 10.

Here, the connection information of the second terminal refers to information that can be obtained by accessing the second terminal without a separate data input by the document viewer, and this includes the personal information of the document viewer, the date and time of the document inquiry, and the location of the document inquiry.

The personal information of the document viewer is the personal information of the member obtained from the member ID of the member who accessed the member (name of the member, the name of the member's organization, e-mail address, contact information, the location of the terminal (device) when registering as a member, information on the terminal (device) when registering as a member, and authentication. Mobile phone information, etc.).

In practice, the personal information of the document viewer stored in the inquiry history storage unit 181 is to be stored only by the member ID, and when the document authentication information is inquired, it is registered in the member information management unit 120 by referring to the member ID of the inquiry history information. It is desirable to search member information together.

The document inquiry date and time is the date and time (date and time) when document authentication information was inquired.

The document inquiry position is the position of the second terminal 20.

In this way, if the inquiry history information for specific document authentication information is accumulated in the inquiry history storage unit 181, and other document viewers can view it by the document authentication information inquiry unit 170, other document viewers authenticate the document. It is easy to recognize who has searched the information how many times, and through this, it is possible to easily determine the authenticity of the document or whether it has been forged or altered.

In particular, the authenticity or forgery of the document can be easily determined by the number of inquiry history information itself. For example, if the document is expected to be distributed to only one person, but if multiple inquiry history information is confirmed, it is easy to confirm that there is a problem with the document. Conversely, even though the document is expected to be distributed to dozens of people, one or two inquiry history If only the information is confirmed, it can be judged that the document is not easily reliable.

Such inquiry history information is also encrypted and stored like document authentication information.

Steps to notify the inquiry history

Inquiry history notification unit 190, the connection information of the second terminal that inquired about the document authentication information, to the document issuer of the document authentication information by email, short message service (SMS), or a push alarm (mobile phone application) To notify.

The method of notifying information by means of e-mail, SMS, push alarm, etc. is a very general technique, so detailed descriptions are omitted.

Thus, the document issuer can check who, when and where, viewed the document they published.

Also, document publishers can establish countermeasures if they believe that their published documents are being abused.

In the present technology, document authentication information and the like are stored in an encrypted form, and since the administrator of the document authentication server does not have a QR code, it is impossible to query document authentication information, especially document images. In other words, if nobody has a QR code, it is impossible to view document authentication information, especially document images, and thus leakage of the main contents of the document can be reliably prevented.

In addition, in the present technology, the QR code itself only includes the inquiry key information, so even if a general person who has not registered as a member shoots the QR code, no information is provided to the general person.

In addition, this technology can prevent fraud because even if you create a fake document by copying only the QR code separately, you can easily match it with the original (document image of document authentication information).

In addition, this technology can easily authenticate the original without the help of a separate legal expert, and in the case of contracts, it is possible to certify the establishment of a normal contract by this technology.

As described above, in situations where the document itself, the document information, or the product information described in the document cannot be clearly trusted, the document authentication information and inquiry history can be easily identified, thereby significantly reducing the time and cost required for document trust. Can be reduced.

In addition, by the present technology, documents can be easily authenticated even with a smart phone, and document authentication information is easily inquired, thereby reducing work processing time and significantly reducing corporate and social costs required for document authentication.

In addition, this technology eliminates the need for separate management personnel in the document authentication process, and minimizes data input by document issuers and document viewers, greatly simplifying the entire document authentication process, and greatly reducing the cost and time consumption required for document authentication. I can make it.

The present invention can also be applied to all documents issued online/offline, certificates for products, and the like.

The present invention can be applied to a specific image or photograph, and can contribute to copyright protection.

In addition, the present invention is applied to a post posted on the Internet, so that the original author and the original of the post can be checked. In other words, it is possible to identify the original and the original author even on the Internet where indiscriminate copying is possible, making it easier to protect rights.

The above description of the present invention is for illustrative purposes only, and those of ordinary skill in the art to which the present invention pertains will be able to understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as being distributed may also be implemented in a combined form.

The scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention. do.

The present invention can be used to confirm the authenticity of various documents such as official documents, private documents, commercial documents, and journals.
