1 is a flowchart illustrating a method for managing distribution of a blockchain-based business plan according to an embodiment of the present invention, and FIG. 2 is a sequence diagram showing a method for managing distribution of a blockchain-based business plan according to an embodiment of the present invention )to be.

3 to 5 show contents of each item of a business plan to be classified as non-encrypted information 10 or encrypted information according to an embodiment of the present invention, and FIGS. 6 and 7 are ratios according to an embodiment of the present invention. It is a chart showing the classification criteria for encryption information 10 or encryption information.

In addition, FIG. 8 is a block diagram showing a document management server 200 for distribution management based on a blockchain-based business plan according to an embodiment of the present invention, and FIGS. 9 and 10 are blockchain-based according to an embodiment of the present invention It is a conceptual diagram showing the business plan distribution management system.

1 and 2, in the distribution management method of a blockchain-based business plan according to an embodiment of the present invention, when a business plan of a preliminary or initial founder is generated, the processor 210 of the document management server 200 ) Classifying the content of each item of the business plan as non-encrypted information 10 or encrypted information (S100), and the processor 210 sends the non-encrypted information 10 to the database 220 of the document management server 200 Storing and transmitting the first transaction including the encryption information and the viewing conditions of the encryption information to the blockchain network 400 to generate the genesis block (S200), from the investor terminal 100 in the document management server 200 1 When receiving the request to view the car, the document management server 200 provides the unencrypted information 10 stored in the database 220 to the investor terminal 100 (S300), the investor terminal in the document management server 200 ( 100) from secondary heat Upon receiving the request, the document management server 200 transmits a second transaction regarding the viewing of the encrypted information to the blockchain network 400 (S400) and the viewing conditions are verified in the blockchain network 400, When an investor satisfies the viewing condition, a block for the second transaction is generated, and the step (S500) of providing encryption information from the blockchain network 400 to the document management server 200 or the investor terminal 100 may be included. have.

Here, the preliminary founder may mean a non-corporate, and the initial founder may refer to a founder of less than 3 years.However, according to the start-up policy, the criteria for the classification of the preliminary founder or the initial entrepreneur may be different. It is not limited.

In step S100 according to an embodiment of the present invention, first, when the contents of the business plan are input by item through the preliminary founder terminal or the initial founder terminal 300, the business plan is written to the database 220 of the document management server 200. Can be created. At this time, the document management server 200 may provide an application (or website, program, etc.) to the preliminary starter terminal or the initial starter terminal 300 so that the contents of the business plan can be input for each item.

For example, referring to FIGS. 3 to 5, when an application is executed with the pre-starter terminal or the initial starter terminal 300, the table of contents of the business plan (ie start-up overview, product service, technology, domestic industry analysis, overseas industry analysis , Start-up item business model, marketing strategy, sales and profit forecast, funding plan and financial soundness) may be classified and displayed, and detailed items may be classified and displayed for each table of contents.

Accordingly, if the table of contents and the detailed items of the business plan are selected by an external input authorized from the pre-founder or the initial entrepreneur, contents may be input for each table of contents and detailed items according to the selection. As shown in FIG. 3, when the management item of the start-up overview is selected, an output window is displayed in which a general status of the CEO, education, whether to complete training related to start-up, type of job before start-up, and start-up-related award results are displayed, and a preliminary entrepreneur or initial Content may be input to an output window displayed by an external input authorized by the founder.

Referring to FIG. 2, when input of each item of the business plan is completed as described above, when the business plan is generated in the document management server 200, the content of the business plan is a data classification unit of the processor 210 of the document management server 200. (211) may be classified as non-encrypted information 10 or encrypted information according to the table of contents and detailed items of the business plan. As described above, the business plan is not generated in the form of a single document, but is generated by inputting contents for each table of contents and detailed items, so that the information classification by the processor 210 can be quickly processed simultaneously with the creation of the business plan.

For example, referring to FIG. 3, in the management section of the entrepreneurship overview, information on whether or not training related to entrepreneurship is completed and awards related to entrepreneurship are non-encrypted information (10), and information on education and job type before starting is encrypted information Can be classified. In addition, referring to FIG. 4, all items of the business model of the start-up item may be classified as encryption information, and referring to FIG. 5, all items of the estimated income statement may also be classified as encryption information.

At this time, the classification criteria for the non-encrypted information 10 or the encrypted information according to an embodiment of the present invention is necessary for determining whether there is no legal problem even if it is disclosed to unspecified unspecified persons, and whether investors are investing. Whether it is recognized and whether or not content related to an important business item is included may be considered and set in advance for each table of contents and detailed items. For example, the product service can be set to be classified as non-encryption information (10) because it is necessary for the investor to check basic information about the start-up before verifying for the investor. Since the content includes important keywords related to business items, it can be set to be classified as encryption information that can only be provided to verified investors.

6 and 7 showing criteria for classification into non-encrypted information 10 or encrypted information according to an embodiment of the present invention are only examples and are not limited thereto. Referring to FIG. 7, in the details of sales and profit forecasts, in the case of detailed items related to target customers and sales by target market, it may be set to be classified as non-encryption information 10, and in the case of detailed items related to the estimated income statement It can be set to be classified as encryption information. That is, even within the same table of contents in the business plan, the classification criteria for the non-encrypted information 10 or the encrypted information may be different for each detailed item.

If the contents of the business plan are classified as non-encrypted information 10 or encrypted information by the data classification unit 211 of the processor 210 according to an embodiment of the present invention, the encrypted information is determined by the data classification unit 211. It can be re-classified into upper information 22 or lower information 21 again. This is to further strengthen the security by dualizing the verification process for investors, and among the encrypted information, contents classified by the data classification unit (211) ), It can be further classified as higher information 22.

For example, referring to FIG. 3, content related to educational background classified as encryption information and job type before start-up may be reclassified as lower information 21. Referring to FIG. 4, similarly, the information on the business model of a start-up item classified as encryption information may be reclassified as lower information 21. However, referring to FIG. 5, information representing the financial situation of the company, such as the calculation of investment cost, estimation of corporate value, planning to attract funds, financial soundness, operating conditions, etc., including estimated profit and loss statements, is first classified as encryption information, and then upper information Reclassified as (22), the access security can be further strengthened.

1 and 2, when the contents of the business plan are classified as the non-encrypted information 10 or the encrypted information through the above-described process (S100), the data is encrypted by the data classification unit 211 of the processor 210. The information 10 may be stored in the database 220 of the document management server 200 (S210). Since the purpose of classifying the non-encryption information 10 is to facilitate access to investors, the non-encryption information 10 can be stored and managed in the database 220 so that the investor can request and read it at any time.

On the other hand, the encrypted information may be included in the first transaction generated by the transaction generating unit 212 along with the viewing conditions to enhance access security and transmitted to the blockchain network 400 (S220, S230). The first transaction may include necessary information for distribution management of encrypted information, such as a timestamp related to the transaction occurrence time, encryption information, and viewing conditions. In the blockchain network 400, a genesis block including encryption information and a viewing condition may be generated based on the first transaction transmitted. At this time, the genesis block is the first block created on the blockchain.

The genesis block is divided into a header and a body, and the header may include a hash value, nonce, merkle root, etc., and the body has a timestamp based on the first transaction. , Encryption information, access conditions, and the like. Blocks based on the second transaction, which will be described later, also have the same structure.

Since the encrypted information can be reclassified into the upper information 22 or the lower information 21 by the data classification unit 211, the reading conditions include the reading conditions of the upper information 22 and the reading conditions of the lower information 21. Can be included. The details of each viewing condition and verification method for the viewing conditions will be described in more detail through step S300, which will be described later.

According to an embodiment of the present invention, the viewing conditions included in the first transaction may be generated as a smart contract-based source code. A smart contract is a technology in which a transaction is automatically concluded between the parties when a certain condition of the transaction is satisfied on the blockchain. That is, the viewing conditions according to an embodiment of the present invention correspond to conditions for determining whether an investor is qualified to access cryptographic information, and an investor is entitled to access cryptographic information according to the viewing conditions. If it is verified as having, management in the blockchain network 400, such as viewing of encrypted information by the investor, can be automatically performed.

In addition, the first transaction according to an embodiment of the present invention may include a condition for discarding the encrypted information. At this time, the discard condition may include a restriction condition that automatically deletes the encrypted information when a capture, copy or print operation of the encrypted information is performed by the investor terminal 100. The revocation conditions can also be generated with smart contract-based source code.

Even if verification of the investor has been made, problems such as unauthorized theft of cryptographic information can occur at any time, so in order to prevent such problems as much as possible, if the capture, copying or printing of the encrypted information is performed by the investor, the encrypted information is automatically A revocation condition that allows revocation can be included in the first transaction.

In order for the above-mentioned viewing conditions and disposal conditions to be automatically performed, viewing of the business plan in the investor terminal 100 must be performed through an application (or website, program, etc.) provided through the document management server 200.

1 and 2, when the first reading request is transmitted from the investor terminal 100 to the document management server 200 after step S200 (S310), the document management server 200 is a database through the communication unit 230 The non-encryption information 10 stored in the 220 may be provided to the investor terminal 100 (S320). In this way, only the non-encrypted information (10) is provided to the investor at the time of the first reading request, thereby inducing the investor's interest and access to the pre-founder or the initial entrepreneur, and at the same time, problems such as theft due to unverified investors' access to the business plan The occurrence can be prevented in advance.

The investor can determine whether to proceed with obtaining additional investment information based on the non-encryption information 10 according to the first reading request, and if additional investment information is required, the document management server 200 through the investor terminal 100 ) To request a second reading. Referring to FIG. 2, when a second viewing request is received from the document management server 200 (S410), a second transaction regarding viewing of encryption information may be generated by the transaction generation unit 212 of the processor 210. There (S430), before generating the second transaction, the reliability evaluation of the investor who requested the second view may be performed by the reliability evaluation unit 213 of the processor 210 (S420).

Reliability evaluation for an investor according to an embodiment of the present invention may be understood as a process of estimating a reliability score based on basic personal information about an investor, investment experience, and credit rating. That is, when the document management server 200 receives a second view request, the reliability evaluation unit 213 of the processor 210 inputs information through the investor terminal 100 and information collected through other credit institutions, etc. Based on these, the reliability score can be estimated and coded to generate reliability evaluation information.

Referring to FIG. 2, when the reliability evaluation information is generated by the reliability evaluation unit 213 (S420), a second transaction including a timestamp related to the transaction occurrence time, the reliability evaluation information for the investor, and the like, the communication unit 230 Through the document management server 200 may be delivered to the blockchain network 400 (S430, S440). When the second transaction is delivered to the blockchain network 400 (S440), whether or not the investor is qualified to access cryptographic information can be automatically verified according to the viewing conditions generated by the smart contract-based source code. Yes (S510). At this time, the viewing condition may include an allowable condition for allowing the encryption information to be viewed when the reliability evaluation for the investor is greater than or equal to a predetermined reference value.

For example, when the reliability score for an investor included in the second transaction is determined to be greater than or equal to a predetermined threshold value by nodes constituting the blockchain network 400 and verification of the investor is completed, the blockchain network ( At 400), a block based on the second transaction may be generated. If it is automatically determined by the nodes constituting the blockchain network 400 that the reliability score for the investor included in the second transaction is below a defined reference value, the block based on the second transaction is generated in the blockchain network 400. In the end, the investor cannot access the encrypted information.

When the viewing conditions are divided into the viewing conditions of the upper information 22 and the viewing conditions of the lower information 21, the above-mentioned allowable conditions may be included for each viewing condition. At this time, the predetermined reference value may be higher in the case of the viewing condition of the upper information 22 than in the case of the viewing condition of the lower information 21. The predetermined reference value in the allowable condition may be determined by considering the investment policy, environment, etc. when creating the first transaction.

2 and 9, when the investor verification is completed, the encrypted information is transmitted from the blockchain network 400 to the document management server 200 (S520), and the investor terminal 100 from the document management server 200 Encrypted information may be transmitted (S530). The dualization of the process of transmitting encrypted information is intended to enhance security by blocking access to the blockchain network 400 of the investor terminal 100 and managing the information transmission route as one.

If it is an authorized investor who does not have any risk of hacking or information leakage, the investor terminal 100 may directly receive the encrypted information through the blockchain network 400, as shown in FIG. 10, and the investor terminal 100 It can be made to participate as a node of the blockchain network 400.

However, for this purpose, in the process of evaluating the reliability of the investor in the reliability evaluation unit 213 of the document management server 200, it is determined whether the investor is authorized, and whether the investor terminal 100 participates in the blockchain network 400. A consensus should be carried out. The investor terminal 100 participates as a node of the blockchain network 400 when the investor terminal 100 determines whether the investor is authorized by the reliability evaluation unit 213 and the agreement between nodes on whether to participate in the blockchain network 400 is completed. By doing so, the document management server 200 can receive the second transaction, and can directly receive the encrypted information through the blockchain network 400.

Referring to Figure 8, the document management server 200 for distribution management of a blockchain-based business plan according to an embodiment of the present invention, when the business plan of the preliminary or initial entrepreneur is created, the contents of each business plan Creates a first transaction including a data classification unit 211 that classifies as non-encrypted information or encrypted information, and a condition for viewing encrypted information and encrypted information, and reads encrypted information according to a second read request from the investor terminal 100 A processor 210 including a transaction generator 212 for generating a second transaction with respect to a database 220 for storing unencrypted information may be included.

In addition, upon receiving a second reading request from the investor terminal 100 in the document management server 200 in the processor 210 of the document management server 200 according to an embodiment of the present invention, the reliability of the investor is evaluated. The reliability evaluation unit 213 may be further included. At this time, the reliability evaluation for the investor may be understood as a process of estimating the reliability score based on basic personal information about the investor, investment experience, and credit rating.
