Description

Document notarization system using unique identification information and blockchain network {SYSTEM FOR NOTARIZATING DOCUMENTS USING UNIQUE IDENTIFICATION IMFORMATION AND BLOCKCHAIN NETWORK}

An embodiment of the present invention relates to a document notarization system using unique identification information and a blockchain network.

When a general company issues a letter of commendation or a letter of appreciation to its workers, there may be a third party who wishes to verify the authenticity of the document years or even decades from the time of issuance, and it may be difficult for that person to determine the authenticity of the document. To do this, contact the issuing company separately and request a verification of authenticity. Afterwards, the company can review the existing issuance-related records and confirm the authenticity after confirmation and verification by the issuance-related staff.

If it is impossible to receive confirmation of the authenticity of the document due to various reasons, such as the company that issued the document going out of business or the previously issued data being lost, a third party will not be able to confirm the authenticity of the document, and the document will actually be Even though it is a genuine product, it may have environmental limitations such as intentional or unintentional denial or concealment of the issuance by the issuing organization.

Therefore, the reality is that it is difficult to establish complete trust between the issuing agency and the users who use the document, as evidence can only be provided by completely trusting and relying on the issuing agency.

This reality can occur not only for companies but also for anyone who can issue a specific document, such as institutions, government offices, and associations. A certification service allows a third party to verify the authenticity of the initially issued document without going through the issuing agency. and related technologies are required.

In order to clearly explain the present invention in the drawings, parts that are not related to the description are omitted, and similar parts are given similar reference numerals throughout the specification.

Figure 1 is a schematic diagram showing the overall implementation and operation of a document notarization system using unique identification information and a blockchain network according to an embodiment of the present invention, and Figure 2 is a schematic diagram showing unique identification information and a blockchain network according to an embodiment of the present invention. It is a block diagram showing the overall configuration of a document notarization system using , and Figure 3 is a diagram showing the operation process of the document register and biometric information authentication control unit according to an embodiment of the present invention.

Referring to Figures 1 and 2, the document notarization system 1000 using unique identification information and a blockchain network according to an embodiment of the present invention includes a document register 100, an NFT issuing unit 200, and issuing unique identification information. It may include at least one of a unit 300, a document notarization information providing unit 400, a document ownership transfer brokerage service providing unit 500, and a biometric information authentication control unit 600.

The document register 100 can receive document information, including a document image file and document issuance information, when the document is first issued by the issuer (or issuing agency) and register it on the blockchain network.

More specifically, when an issuer (or issuing agency) first issues a document such as a certificate, diploma, commendation, appreciation plaque, certificate, or contract, a document image file including a scanned image file or photo image file of the document, When document information, including document issuance information, is uploaded using the homepage or dedicated application, the uploaded document information is registered on the blockchain network, thereby preventing arbitrary alteration or deletion of information by a third party. can be processed.

Here, the document issuance information may include at least one of the contents of the document to be notarized (or issued), information on the issuer (or issuing agency), and information on the date of issuance of the document, but in this embodiment, the document issuance information In addition to being limited to the above, various information that can prove the authenticity, ownership, etc. of the notarized (or issued) document can be additionally included.

Meanwhile, the document registration unit 100 additionally registers at least one biometric information such as iris information and fingerprint information of the original document owner, separately replicates the document issuance information before registration on the blockchain network, and then issues the duplicated document. Information can be generated as metadata for biometric information, and biometric authentication information with the generated metadata can be stored and managed in the database 40. Here, the owner of the original document, unlike the issuer (or issuing agency), is the person who first actually received and currently owns the original document such as a certificate, diploma, commendation, appreciation plaque, certificate, or contract (if purchased or transferred). , or a person, institution, or organization with ownership, and additional authentication processes related to such biometric information will be described in more detail later in the section on the biometric information authentication control unit 600.

The NFT issuing unit 200 can issue a non-fungible token (NFT) for document information. More specifically, it can be issued by applying a hash function, a blockchain-based computer encryption technology, to document information to extract a unique hash value and record it in an NFT.

The NFT generated by the NFT issuing unit 200 can be recorded on the blockchain network, and ownership of the original document can be authenticated or proven using the NFT. The NFT issuing department 200 records the issued NFT on the blockchain network to authenticate or prove the ownership of the original document generated by the NFT. In addition to this method, by registering the NFT information on a separate website server Ownership of the model video can be authenticated or proven later. NFT authentication or proof in the NFT issuing unit 200 uses a hash function used for NFT issuance. This hash function is an irreversible one-way function, and only one hash value can be extracted from one original object. Therefore, the authenticity can be verified by backtracking the unique hash value recorded in the NFT and checking the image and corresponding information about the original document linked to the hash value.

In this way, the NFT issuing unit 200 issues the image file and issuance information of the uploaded document as an NFT at the same time as the original document is registered, and then serves to transfer the ownership of the NFT to the original document issuer.

The unique identification information issuing unit 300 issues unique identification information matched with the NFT, and may issue it in a form that can be attached to the original printout of the document or attached to the document image file. The unique identification information according to this embodiment may be issued in the form of at least one of a QR code, bar code, and unique serial number. Here, the QR code and barcode are printed in the form of a sticker and attached to the document, or when the document is printed and issued, the QR code or barcode is printed together on the document to provide the original document with the QR code or barcode printed on it. You can. In addition, the unique serial number may be printed together on the document when the document is printed and issued to provide an original document with the unique serial number printed on it, or it may be printed in the form of a sticker and attached to the document. In this way, the unique identification information issuing unit 300 distributes or distributes the original document in the form of attaching or printing a two-dimensional code such as a QR code or barcode, or prints or separately prints the unique serial number by including it in the document contents. It can be distributed or distributed in the form of a sticker attached, etc.

The document notarization information provider 400 can provide document information on a preset web page using NFT when recognizing unique identification information.

More specifically, the document notarization information provider 400, when unique identification information exists in the form of at least one two-dimensional code among a QR code and a bar code in the original document, when the two-dimensional code is recognized through scanning. , After accessing the web page using the URL information included in the two-dimensional code, extract the NFT that matches the unique code included in the two-dimensional code through the integrated management server 20 that provides the web page, Using the extracted NFT, document information registered in the blockchain network can be returned and made available for viewing through the corresponding web page. As described above, NFT authentication or proof uses a hash function used in NFT issuance. This hash function is an irreversible one-way function, and only one hash value can be extracted from one original object, so NFT By backtracking the unique hash value recorded in and providing the document image file and document issuance information for the original document linked to the hash value, the authenticity can be verified.

In addition, the document notarization information provider 400, when unique identification information exists in the form of a unique serial number in the original document, when the two-dimensional code is entered into the input window of the corresponding web page, the integrated management server 20 You can extract the NFT that matches the unique serial number and unique code, and use the extracted NFT to return the document information registered in the blockchain network and make it available for viewing through the corresponding web page. As described above, NFT authentication or proof uses a hash function used in NFT issuance. This hash function is an irreversible one-way function, and only one hash value can be extracted from one original object, so NFT By backtracking the unique hash value recorded in and providing the document image file and document issuance information for the original document linked to the hash value, the authenticity can be verified.

In this way, the document notarization information providing unit 400 provides the document and information at the time of the original document issuance of the code value included in the unique identification information, allowing anyone to determine whether the document is identical and authentic, and ensures that the document exists. If you enter an unauthorized code (i.e. unique identification information), a counterfeit document will be returned, allowing you to determine that the document is not genuine.

The document ownership transfer brokerage service provider 500 provides at least one transfer brokerage service among the sale, consignment, and gift of ownership of the document to a third party based on NFT, but in advance when selling and consigning ownership of the document. It provides a payment service for a set amount, and a portion of the profits from the payment service can be paid to the issuer (or issuing institution).

In this way, since the NFT delivered to the issuer was issued based on the document information registered at the time of issuance, ownership can be proven in the process of distributing or distributing the document online, and at the same time, authenticity can be determined online. there is. Additionally, an issuer who owns an NFT can sell, entrust, or deliver (gift) the ownership of the NFT to a third party, thereby providing additional added value to the issuer of the original document.

The biometric information authentication control unit 600 receives at least one biometric information of the iris recognition information and fingerprint recognition information of the original document owner and the issuance date and time information of the document to be certified through the biometric information upload web page, respectively, If there is biometric authentication information stored in the database that matches the information uploaded through the web page, the recognition process of the unique identification information is controlled to be executable, and if there is no matching biometric authentication information, the unique identification information is The recognition process can be controlled or controlled so that it cannot be executed.

More specifically, as shown in FIG. 3, biometric information such as fingerprints or iris of the owner of the original document (the person who received the original document from the issuer or issuing institution) is first sent to the website through the communication terminal 10. When uploaded (①) through a dedicated application, the integrated management server (20) inputs document issuance information, that is, issuer information and issue date information, for the original document owned by the owner as metadata of the uploaded biometric information, and enters the biometric information into the biometric information. Authentication information is generated and the generated biometric authentication information is stored in the database 40 (②).

Afterwards, the owner of the original document must perform a biometric authentication process first, rather than confirming the authenticity of the document he or she owns to a third party or entering the unique identification information present in the document in order to sell it. At this time, if authentication is not completed through performing the biometric authentication process, the authentication process for the unique identification information cannot be performed, so it is designed to be performed first with the biometric authentication process. Accordingly, when the owner of the original document inputs his or her biometric information through a third party's communication terminal 30, it is uploaded to the biometric information authentication control unit 600 of the integrated management server 20 through a website or dedicated application. At the same time, document information for the document, that is, issuer information and issue date information, can be input and uploaded to the biometric information authentication control unit 600 of the integrated management server 20 along with the corresponding biometric information.

At this time, the biometric information authentication control unit 600 checks whether biometric authentication information matching the uploaded biometric information and document information is already registered in the database 40, and confirms that the biometric authentication information exists (④). After confirming the existence of biometric information to a third party, that is, notifying the third party that biometric authentication has been successfully completed, proceed with the authentication process to confirm the authenticity of the subsequent document by entering the unique identification information present in the document to be certified. Make this possible. At this time, if the corresponding biometric authentication information does not exist in the database 40, it is controlled so that the authentication process using the unique identification information cannot be executed even if the code value of the unique identification information is entered through the third party's communication terminal 30. , the authenticity of the document cannot be confirmed using unique identification information and NFT. Accordingly, the authenticity of the document can be accurately determined even through theft or theft of the original document and falsification of the identity of the original owner.

According to this embodiment, anyone can easily and conveniently prove the authenticity of various issued documents that are closely used in our lives, such as certificates, diplomas, commendations, appreciation plaques, certificates, and contracts, and the issuer or issuing organization can verify the authenticity of the document. It is possible to provide a reliable authentication service by a third party so that cooperation is impossible, denial of issuance regarding authenticity, destruction of issuance records, and forgery/falsification of issuance facts are prohibited.

Additionally, by using a blockchain network, contamination such as document forgery and destruction by third parties can be prevented as long as document information exists in the network.

In addition, the NFT received by the issuer at the time of publication can be sold and delivered to external parties, so it can add added value to the issued document. For example, the first paper the winner received in the past has document information registered using the present invention. In this case, anyone can check the authenticity of the paper, and the first issuing institution (university) can obtain high added value because it can be distributed and traded later by owning the NFT of the document.
