1 is a conceptual diagram showing a blockchain-based notarization system according to an embodiment of the present invention.

In Figure 1, a notarization method through a blockchain-based notarization system is disclosed.

Referring to FIG. 1, the blockchain-based notarization system includes a block chain network, a notarization service providing node 110, a personal node 120, a proof information providing node 130, a proof information receiving node 140, and a notary node 150. ) Can be included.

The blockchain network 100 may create a blockchain that stores and/or processes various transactions generated by nodes constituting the blockchain network 100. On each of the plurality of blocks included in the blockchain, transaction information generated for a certain period of time (block creation time) and verified by the node may be included. In addition, after verification of the node, information on the block connected to the block chain may be propagated to nodes constituting the block chain network 100.

Blocks connected to the blockchain can be created based on mining, and various methods such as proof of work (POW), proof of stake (POS), and delegated proof of stake (DPOS) can be used. Blocks are mined including information of previous blocks, and this mining method can prevent modulation of transaction information recorded on the block.

Each block constituting the blockchain is information on the movement of cryptocurrency occurring on the blockchain, programming code (or blockchain code) to perform a specific algorithm based on the blockchain such as smart contract, smart contract It may include transaction information generated based on.

Nodes constituting the blockchain network 100 include a notary service providing node 110, a personal node 120, a proof information providing node 130, a proof information receiving node 140, a notary node 150, etc. I can.

The notarized service providing node 110 provides personal information (eg, educational background information, career information, and/or personal information to the personal node 120 through the proof information providing node 130, the proof information receiving node 140, and the notary node 150). It may be a node for providing a notarized service for identification information, etc.). The notary service providing node 110 may store programming code such as a smart contract for providing a notarized service on the blockchain. Notarized through a transaction between the notarized service providing node 110 and the call of the smart contract stored on the block and the private node 120, the proof information providing node 130, the proof information receiving node 140, and the notary node 150 Service can be provided. The specific notarization process on the blockchain will be described later.

The individual node 120 may be a node subject to notarization. For example, the individual node 120 may be a node of an individual who wants to notarize a personal career document for studying abroad.

The individual node 120 requests notarization to the proof information providing node 130 and/or the notary node 150, and the proof information providing node 130 and/or the notary node 150 provides notarization information according to the notarization request. It can be created and stored on the blockchain. The notarized information on the blockchain may be transmitted to the proof information receiving node 140.

The proof information providing node 130 may be implemented to generate personal information according to the proof request of the personal node 120 and to provide the generated personal information on a blockchain. The proof information providing node 130 may perform an authentication procedure for an individual according to the request of the personal node 120, generate the requested personal information, and upload it on the blockchain.

For example, when the proof information providing node 130 is a university node and receives personal information (graduation proof documents, academic records, etc.) for studying abroad from an individual as a university node, it generates personal information and converts the generated personal information to a blockchain. The evidence information may be transmitted to the receiving node 140 through the method.

The notarization node 150 may be implemented for an additional notarization procedure when notarization by the proof information providing node 130 is impossible. For example, it may be assumed that the personal information is in a first language (eg, a Korean version), and notarization is required after the translation of the second language. In this case, in the past, additional costs were paid through a separate notary agency, and notarized documents had to be created through translation through a notary agency. However, in the embodiment of the present invention, the verification procedure for the accuracy of translation on the network is performed through a translation and verification procedure for translation based on a plurality of notarized nodes 150 without going through a separate notary organization for such translation. Can be done.

If the proof information providing node 130 can directly generate personal information in the second language, the notarization procedure based on the notary node 150 may not be performed. Conversely, when the proof information providing node 130 can generate personal information only in the first language and translation into the second language is required, a notarization procedure based on the notary node 150 according to the embodiment of the present invention is performed. Can be.

As a specific example, in the case where proof documents related to grades are issued only in Korean for studying abroad, a notarization process is performed through the notarization node 150, and if the proof documents related to grades can be issued in English for study abroad, the notarization node The notarization procedure through (150) may not be performed. A notarization method through the notary node 150 will be described later.

The proof information receiving node 140 may be implemented to receive the personal information generated by the proof information providing node 130 and/or the personal information notarized by the notary node 150.

The proof information receiving node 140 may receive personal information through a block chain, reflect the personal information without additional verification as to whether the received personal information is authentic, and process subsequent procedures.

Hereinafter, in an embodiment of the present invention, based on a block chain network, a notarized service providing node 110, a personal node 120, a proof information providing node 130, a proof information receiving node 140, and a notary node 150 A notarization process is initiated.

The procedure on the blockchain disclosed below may be performed based on the smart contract recorded on the block by the notary service providing node 110.

2 is a conceptual diagram showing a notarization procedure on a blockchain according to an embodiment of the present invention.

In FIG. 2, a procedure for performing personal authentication and requesting personal information to a node providing evidence information based on personal authentication is disclosed.

Referring to FIG. 2, a personal authentication procedure for requesting personal information from a personal node may be performed.

The personal authentication procedure may be a procedure for checking whether an authority for requesting personal information exists. The personal authentication procedure may be performed based on the private key assigned to each individual node 220. The supporting information providing node 210 may allocate a public key and a private key for each of the individual nodes 220 in advance, and authentication for the private node 220 is performed by the assigned private node 220 It can be performed based on the private key of. The proof information providing node 210 may be a user equipment of a school institution, and a personal node may be a user equipment of a student.

In order to request a blockchain-based notarization process, the node 210 providing proof information proceeds with a verification process for the personal identity, and when the personal identity is confirmed through the verification process, a personal identity verification completion transaction notifying the completion of the personal identity verification (213) can be transmitted. Verification procedures for personal identification may include online or offline procedures for personal identification verification. The verification procedure for personal identification may be an identification procedure on a blockchain or a non-blockchain.

When the personal identification completion transaction 213 is transmitted, a private key and a public key may be allocated to the personal node 220 based on the smart contract. In this case, information on the public key allocated to the personal node 220 is also transmitted to the proof information providing node 210 so that the personal identification information and the public key may be matched.

The personal node 220 may sign the personal information request transaction 215 with the assigned private key and transmit it together with the public key, and the personal information request transaction 225 may be transmitted on a blockchain. When the personal information request transaction 225 occurs from the personal node 220, the personal information request transaction 225 and the personal information request transaction 225 to the proof information providing node 210 that has performed authentication for the personal node 220 based on the smart contract. The public key of the private node 220 may be transmitted.

The proof information providing node 210 receives the personal information request transaction 225, decrypts the personal information request transaction 225 based on the public key of the personal node 220, and requests according to the personal information request transaction 225 Personal information can be generated. Personal information may be a variety of information. When the subject of the proof information providing node 210 is a university and the subject of the individual node 220 is a student who intends to study abroad, the personal information may include graduation proof information, grade proof information, and the like.

In this case, the personal information generated by the proof information providing node 210 may be transmitted through the personal information transaction 216 and stored on the block. The personal information transaction 216 generated by the proof information providing node 210 is firstly encrypted with the public key of the personal node 220 for protection of personal information, and is generated by the proof information providing node 210 In order to authenticate that it is, it may be secondaryly encrypted with the private key of the node 210 providing proof information. In the case of encryption with the public key of the private node 220, since it can be decrypted only with the private key of the private node 220, it is impossible to check the personal information of a third party. In addition, when it is decrypted with the public key of the proof information providing node 210, it may be proved that the transaction is generated by the proof information providing node 210 as a transaction generated with the private key of the proof information providing node 210.

In the method disclosed above, a request for personal information for notarization can be performed on the blockchain.

The above-described encryption method of personal information is an example of a method for preventing a third party from decrypting personal information, and various other encryption methods are applied to personal information to prevent the third party from decrypting personal information.

3 is a conceptual diagram showing a notarization procedure on a blockchain according to an embodiment of the present invention.

In FIG. 3, after providing personal information, a method for transmitting the provided personal information to an evidence information receiving node is disclosed.

Referring to FIG. 3, personal information generated by the proof information providing node, encrypted on a block, and stored may be transmitted to the proof information receiving node 320.

The personal node 310 may transmit a personal information transfer request transaction 313 including identification information of the proof information receiving node specifying the proof information receiving node 320 on the block.

The personal information transfer request transaction 313 may also include information on a personal information transfer timing when personal information should be transferred to the node 320 at any time. When such personal information delivery time is specified, a deadline block in consideration of the personal information delivery time and block generation prediction time may be set on the block chain so that the delivery of personal information is performed before the creation of the deadline block.

When the personal information transfer request transaction 313 is transmitted, as described above, based on the smart contract, personal information is first encrypted with the private key of the supporting information providing node, and secondly encrypted with the public key of the private node 310 The transaction 323 may be transmitted to the evidence information receiving node 320.

The proof information receiving node 320 may receive the personal information transaction 323 and decrypt the personal information transaction 323.

In order to decrypt the personal information transaction 323, the proof information receiving node 320 first performs decryption with the public key of the proof information providing node to confirm that the personal information transaction 323 is generated by the proof information providing node. I can.

Next, after the first decryption, the proof information receiving node 320 needs the private key of the private node 310 for the second decryption, but because only the private node 310 knows the information on the private key, it is impossible to decrypt itself. Do.

Accordingly, the proof information receiving node 320 may request the personal node 310 to input the private key to confirm the personal information.

The personal node 310 can input the private key according to the request of the proof information receiving node 320, and the proof information receiving node 320 can receive the decrypted personal information through the input of the transmitted private key. In addition, a decryption completion transaction 326 for personal information may be transmitted to the personal node 310.

Through the above procedure, personal information may be transferred from the proof information providing node to the proof information receiving node 320 on the blockchain.

The encryption/decryption of the personal information disclosed in FIGS. 2 and 3 is performed based on the public key of the proof information providing node and the private key of the private node as an example, and various other encryption methods may be used, and this embodiment is also shown. It may be included in the scope of the present invention.

In FIGS. 2 and 3, when a separate notarization procedure for personal information is not required, it is a transfer procedure of personal information, and in the embodiment of the present invention, operation on a block chain when a separate notarization procedure is required is started. . For convenience of explanation, a case where notarization is required for language translation is disclosed, but a notarization node-based notarization procedure according to an embodiment of the present invention may be performed in a procedure that requires not only language translation but also various other notarizations.

4 is a conceptual diagram showing a notarization method on a block chain according to an embodiment of the present invention.

In FIG. 4, a procedure for notarizing personal information for studying abroad is exemplarily disclosed in the case of notarization requiring language translation. Specifically, it may be assumed that the proof information providing node 410 is a Korean university node, the proof information receiving node 440 is a US university node, and personal information is a graduation certificate, transcript, etc. required for studying abroad. If personal information is provided in English by the evidence information receiving node 440, the procedure disclosed in FIGS. 2 and 3 may be performed, but the personal information is provided only in Korean by the evidence information receiving node 440. If so, additional notarization procedures may be necessary. In the existing case, a notary was requested from a notary company, and the notary company proceeded with the notarization process. However, according to an embodiment of the present invention, it is possible to perform the notarization procedure on the blockchain without a separate notary company.

4, when a notarization operation is required, a personal information transaction 415 encrypted by the proof information providing node 410 is transmitted to the notary node 420 through a block chain, and the notary node 420 is encrypted. The notarization operation may be performed through the decryption of the personal information transaction 415.

For example, as described above, encryption based on the private key of the proof information providing node 410 and the public key of the private node 430 may be performed on a document to be notarized including personal information. Alternatively, encryption based on the private key of the proof information providing node 410 and the public key of the private node 430 may be performed by dividing the personal information included in the document to be notarized for each sub-item.

The personal information transaction 415 encrypted by the proof information providing node 410 may be transmitted to the notary node 420 through a block chain, and the notary node 420 decrypts the personal information transaction 415 can do. For example, decryption may be performed primarily based on the public key of the proof information providing node 410, and secondarily based on the private key of the personal node 430. Specifically, the notary node 420 first decrypts the public key using the public key of the disclosed proof information providing node 410, and then, requests the private node 430 to input the private key. Secondary decryption of personal information can be performed according to the input of the private key.

In this way, the notarization node 420 may decrypt the acquired personal information and perform translation/verification work on the personal information.

The notary node 420 may encrypt the final result determined after the translation/verification operation and transmit it on the blockchain. Specifically, the notarization node 420 firstly performs encryption based on the private key of the notary node 420, and secondly performs encryption based on the public key of the private node 430, so that the first notarization result transaction 423 ) Can be created and transmitted on the blockchain.

A second notarization result transaction 426 may be generated based on one first notarization result transaction 423 or a combination of a plurality of first notarization result transactions 423 on the blockchain, and a second notarization result transaction 426 ) May be transmitted to the evidence information receiving node 440. When the notarization work for the entire notarization target document is performed, when the translation/verification work for each notarization target item is not performed, one first notarization result transaction 423 may be generated. Conversely, when the notarization work on the entire notarization target document is performed, when the translation/verification work is performed for each notarization target item, a plurality of first notarization result transactions 423 may be generated.

The proof information receiving node 440 may receive the second notarization result transaction 426 and decrypt the second notarization result transaction 426. In order to decrypt the second notarization result transaction 426, the proof information receiving node 440 primarily performs decryption with the public key of the notary node 420, and performs a second notarization through a notarization operation by the notary node 420. It can be seen that the resulting transaction 426 has been created. Likewise, after the first decryption, the proof information receiving node 440 needs the private key of the private node 430 for the second decryption, but only the private node 430 can know the information about the private key of the private node 430. Therefore, it is impossible to decrypt itself. Accordingly, the proof information receiving node 440 may request the personal node 430 to input the private key to confirm the notarization result of the personal information. The personal node 430 may input the private key according to the request of the proof information receiving node 440, and the proof information receiving node 440 based on the input of the transmitted private key, the notarization result of the personal information. May be received, and a decryption completion transaction for the notarization result may be transmitted to the personal node 430.

5 is a conceptual diagram showing a notarization method on a block chain according to an embodiment of the present invention.

In Fig. 5, the translation/verification work of the notary node on the blockchain is started.

Referring to FIG. 5, in the method of verifying personal career based on the block chain according to an embodiment of the present invention, a notarization procedure may be performed by a pool of notarized nodes.

At least one notary node from the pool of notary nodes is selected as the work notarization node 510, and a translation procedure by the work notarization node 510 may be performed.

At least one work notarization node 510 generates a translation result, and at least one of the other notarization nodes other than the work notarization node 510 from the notary node pool can verify the translation result as a verification notarization node 520 have.

The at least one verification notarization node 520 may check a difference between the original and the translated version and determine whether to pass/fail (P/F) for each item. P/F can be determined for the entire translation, or P/F for each item can be determined. Hereinafter, in an embodiment of the present invention, a method of determining a P/F for each item is disclosed for convenience of description.

For example, if the document to be notarized includes a name item as the first item, an address item as the second item, and a grade item as the third item, P/F for the first item (name item), the second item ( Each of the P/F for the address item) and the P/F for the third item (the grade item) may be determined.

When the verification notary node 520 having a first threshold value (eg, a majority) or higher for a specific item among at least one verification notary node 520 determines a pass, the corresponding item may be determined as a pass.

If the verification notarization node 520 less than the first threshold (for example, a majority) determines the pass for a specific item among at least one verification notarization node 520, the item is included as a review item and work notarized again. By selecting the node 510, a review of the corresponding item may be performed.

In addition, according to an embodiment of the present invention, when a plurality of job notarization nodes 510 are selected for a specific item, a job that receives the highest pass by performing P/F on the result of each of the plurality of job notarization nodes 510 The result of the notary node 510 may be determined as the final result. For example, for the notarization work on the grade item, the first work notarization node to the fifth work notarization node are selected, and each of the first work notarization node to the fifth work notarization node is 2 Each of the work result, the third work result, the fourth work result, and the fifth work result can be presented.

The first work result, the second work result, the third work result, the fourth work result, and the fifth work result are delivered to a plurality of verification notarized nodes, and the first work result, second work result, third work result, and Whether or not P/F for the 4 work result and the 5th work result can be determined. If the second work result has a pass ratio that exceeds the threshold value and has the highest pass ratio among the first to fifth work results, the second work result may be selected as the final result for the grade item.

The P/F result for the work result of each of the verification and notary nodes 520 may be stored on the blockchain, and the work notary node 510 may check the P/F result.

The final result may be stored on the blockchain as a notarized result of the grade item, combined with other items, and transmitted to the proof information receiving node 550. As described above, a second notarization result transaction is generated through a combination of a plurality of first notarization result transactions through a block chain, and the second notarization result transaction may be transmitted to the evidence information receiving node 550.

When at least one work notarization node 510 generates a full translation for the original and the verification notarization node 520 determines P/F for the entire translation, the work results of the plurality of verification notarization nodes 520 The P/F is determined, and the work piece having the highest pass ratio can be determined as the final result. As described above, a second notarization result transaction 555 is generated based on one first notarization result transaction through the block chain, and the second notarization result transaction 555 can be transmitted to the evidence information receiving node 550. have.

According to an embodiment of the present invention, rewards may be given to the work notarization node 510 and the verification notarization node 520 on the blockchain. For example, a token (or virtual currency, cryptocurrency, etc.) may be generated according to the creation of a block on the blockchain, and the generated token is the work (eg, translation) of the work notarization node 510 and/or It may be provided as a compensation for verification of the verification notary node 520. The P/F result for the work result of the work notarization node 510 can be accumulated, and the reliability according to the P/F result of the work result of the work notarization node 510 is determined, and this reliability is then determined for the notarization work. It can be related to the allocation and distribution of tokens. The higher the reliability of the work notarization node 510, the greater the amount of notarization work, and the allocation of tokens (or rewards) according to the notarization work may be relatively large.

6 is a conceptual diagram showing a notarization method on a block chain according to an embodiment of the present invention.

In FIG. 6, a method is disclosed in which a work notarization node matched for each of a plurality of items performs a notarization operation, and a plurality of verification notarization nodes perform a verification work on each of a plurality of items.

Referring to FIG. 6, the document to be notarized is divided into a plurality of items based on the recognition of the contents included in the document to be notarized, and the notarization procedure for each of the plurality of items is performed by each of the plurality of working notary nodes. Can be done.

Each of the plurality of items can be divided so that the work notary node does not specify personal information. For example, if the verification item of the document to be notarized is a name, address, and last name, the name is assigned to the first work notarization node pool 613 as the first item 610, and the address is subtracted as the second item 620. 2 It is allocated to the work notarized node pool 623, and the grade may be assigned to the third work notarized node pool 633 as the third item 630. Nodes belonging to the first work notarized node pool 613, the second work notarized node pool 623, and the third work notarized node pool 633 may not overlap. This work notarization node pool can be determined according to the amount of work and the nature of the work. For example, for items that do not have a large amount of work and have a low error rate (e.g., name, address, etc.), a pool of work notarized nodes including relatively few notary nodes is determined, the amount of work is large, and the error rate For these many items (for example, grade items, etc.), a pool of work notarized nodes including relatively many notarized nodes is determined, and translation work can be performed. The translation error rate may be determined in consideration of the deviation of the P/F according to the existing translation result.

Further, according to an embodiment of the present invention, the amount of translation work is divided in consideration of the difficulty level and the amount of translation of the translation item, and a time point for receiving the translation work result may be determined. For example, the completion time of the notarization procedure for the personal information may be determined in consideration of the time when the block is generated and the time when the personal information is transmitted to the node receiving the evidence information. A specific block may be set as a deadline prediction block as a deadline for transmission of personal information to the proof information receiving node. Based on the deadline prediction block, the notarization completion prediction block may be determined so that the notarization work is completed before that, and the amount of translation work in consideration of the difficulty of the translation item and the amount of translation so that the notarization work is completed before the creation of the notarization completion prediction block. This can be assigned to multiple work notarization nodes.

In order not to specify personal information for each of a plurality of items, a learning result (eg, machine learning) for personal information may be used. For example, in order to divide a plurality of items in which personal information cannot be specified among the full text, personal information and non-personal information are separated from the full text, and sub-personal information (name, resident Separation can be performed through recognition of each of the numbers, addresses, etc.). When the items are divided, combination identification information for subsequent combinations of items may be given, and a plurality of items may be combined based on the combination identification information to regenerate one personal information document.

According to an embodiment of the present invention, a plurality of work notarization nodes (or a plurality of work notarization node pools) are determined based on the items divided from the document to be notarized, and each of the plurality of work notarization nodes (or a plurality of work notarization node pools) May proceed with the notarization process for each divided item. Hereinafter, for convenience of description, it is assumed that a task notarized node pool task is performed.

For example, the first work notarized node pool 613 for translation for the first item (name) 610, the second work notarized node pool 623 for translation for the second item (address) 620 ), a third work notarization node pool 633 for translation for the third item (grade) 630 may be determined.

The first item (name) 610 is transferred to the first work notarized node pool 613 to perform translation work, and the second item (address) 620 is transferred to the second work notarized node pool 623 The translation work is performed, and the third item (grade) 630 is delivered to the third work notarized node pool 633, so that the translation work may be performed.

The verification work can likewise be performed item by item. The first verification notarized node pool 616 for verification of the first item (name) 610, the second verification notarization node pool 626 for translation of the second item (address) 620, third A third verification notarized node pool 636 for translation for the item (grade) 630 may be determined.
