Description

Project information management means using the blockchain system {Means for project management using block chain system}

The present invention relates to a project information management means using a blockchain system. More specifically, by distributing and storing project information created by an administrator using a dual blockchain system, the objectivity and transparency of project information are strengthened. , It is about a project information management method using a blockchain system that improves security, confidentiality, and processing (storage) speed.

What is a project?

It is used in various senses, and refers to a unit task or project that is of a one-time nature, such as system development, program design, research and development plan, or construction work, etc., carried out to achieve a specific purpose.

In general, it refers to an organic and systematic plan for research or development of a new business, and refers to specific goals, learning activities for the plan, action plans, etc.

Projects are generally promoted at the research level of companies or universities, but in the case of large-scale research plans that are carried out according to a long-term plan with a certain purpose, they are often carried out under the leadership of the government.

This is especially true in cases where the number of people required is large or continuous and massive investment of funds is required.

Depending on the nature of the various projects, the conclusion of a project performance contract between the client and partners must be accompanied by objectivity, reliability, and sometimes confidentiality.

However, currently, there are inadequacies in maximizing objectivity, reliability, confidentiality, and security by simply recording project execution contracts, tasks, and progress on a computer or storing them in files.

Blockchain is,

Distributed computing where small data called 'blocks' are stored in a distributed data storage environment based on chain-type links created based on the P2P method, so that no one can modify them arbitrarily and anyone can view the results of changes. It is a technology-based ledger management technology.

This is fundamentally a form of distributed data storage technology. It is a change list in which continuously changing data is recorded in all participating nodes, and arbitrary manipulation by operators of distributed nodes is impossible.

The hash value is,

It is a cipher-like number that abbreviates file characteristics to prove the identity of the copied digital evidence and is generally referred to as the 'fingerprint of digital evidence' during the investigation process.

It is a value that maps data with various lengths to data with a fixed length.

In other words, it is a function that maps data of arbitrary length to data of fixed length.

The value obtained by the hash function is called a hash value, hash code, hash checksum, or simply hash.

One of its uses is in a data structure called a hash table, which is widely used in computer software for very fast data retrieval.

Hash functions can accelerate database searches or table searches because they can find duplicate records in large files.

Therefore, the present invention applies blockchain technology that can transparently record and store project-related work in a project system that creates and manages project information, thereby preventing forgery and falsification of data as a public transaction ledger. However, by using both private blockchain and public blockchain simultaneously, the effectiveness and efficiency of the project system is maximized by taking advantage of the advantages of each, and the objectivity, transparency, reliability, confidentiality, and processing (storage) speed of project information are strengthened. , We seek to establish and provide a more systematic and robust project information management tool.

Accordingly, as prior art regarding project information management means using a blockchain system,

As shown in (a) of Figure 7, “Project Management System and Project Management Method” (hereinafter referred to as ‘Prior Art 1’) of Republic of Korea Patent Publication No. 10-1841161,

Performance information for each process of the project and feedback information corresponding to the performance information are input from the consignee terminal and the client terminal, respectively. If a dispute mediation request occurs from one or more of the consignee terminal and the client terminal, a log entry is set to provide performance information and It relates to a project management system and project management method that can generate data that serves as a basis for mediating disputes between a consignee and the client by generating only information corresponding to log items among feedback information as a log file.

As another prior art, as shown in (b) of Figure 7,

“Blockchain-based project management service provision method, device, and program” (hereinafter referred to as ‘Prior Art 2’) of Republic of Korea Patent Publication No. 10-2061448,

Obtaining project information, classifying the tasks of the project, determining the type of the project, selecting one or more performers to perform the project based on the classified tasks and the type of the project. A method of providing a blockchain-based project management service, including the step of determining, determining tasks to be performed by each of the one or more performing entities, and transmitting information for management of the project to a node on the blockchain. will be.

As seen, prior art 1 to prior art 2 relate to a project management system, and are similar in technical field to the present invention, but are different from the technical idea of the present invention.

In more detail, the present invention converts project information created and recorded from a project management tool into data to be combined into a blockchain in order to apply it to blockchain technology, and encrypts it so that the manager can easily By not only enabling reading and sorting of data combined in the blockchain, but also converting the data into a hash value and recording the hash value in the blockchain, the objectivity, transparency, reliability, and confidentiality of project information management are strengthened. Of course, this is to provide management means to improve processing (storage) speed.

Therefore, there is a difference between the prior art 1 and prior art 2 in the problem to be solved (purpose of the invention), the solution (component) to solve the problem, and the effect of the invention resulting from this, so the technical characteristics are different. I will do it.

Referring to Figure 3, looking at the mechanism of the present invention in more detail,

First, access the project information management means (1) using the blockchain system of the present invention, (▶ S100, system access step)

The manager uses the project information management means (100) to create project information (D) to be traded with the first blockchain (BC1), (▶ S200, project information creation step)

The created project information (D) is converted into block data (Db) by the blockchain data generation means (200), (▶ S300, block data generation step)

The first project information is recorded in the first blockchain (BC1) by the blockchain recording means 310. (▶ S500, first blockchain recording step)

At this time, when the block data (Db) is recorded in the first blockchain (BC1) by the first project information blockchain recording means 310, the first electronic money (EC1) issued by the management entity is used to 1 By concluding a transaction with Special Node (SN1), block data (Db) is recorded in the first blockchain (BC1) with approval by an authorized participant. (▶ S400, participant approval step)

In the block data generation step (S300),

A metadata generation step (S310) in which the project information (D) created by the manager from the project information management means (100) is converted into metadata (D') by the metadata creation unit (210);

At this time, when the block data (Db) is recorded in the second blockchain (BC2) by the second project information blockchain recording means 320, the second electronic money (EC2) issued from the electronic money exchange is used, Complete the transaction with the second special node (SN2) and have the block data (Db) recorded in the second blockchain (BC2). (▶ S700, electronic money use step)

In the participant approval step (S400), the first electronic currency (EC1) used to record block data (Db) in the first blockchain (BC1) is issued by a management entity with transaction approval and block creation authority. and

In the electronic money use step (S700), electronic money (EC), which is used to record the hash value for block data (Db) in the second blockchain (BC2), is the digital currency required for conventional public blockchain transactions. It is currency.

In the flow of the system as described above, the blockchain data generation means 200 encrypts the project information (D) so that it is recorded in the first blockchain (BC1) and converts it into block data (Db),

A metadata generator 210 that converts the project information (D) created by the manager from the project information management means (100) into metadata (D') in order to record it in the blockchain (BC). );

a code data generator 220 that processes the metadata (D') created by the metadata generator 210 and converts it into encrypted code data (D");

The code data (D") encrypted by the code data generator 220 is processed so that it can be registered in a format used in the blockchain (BC), and converted into hexadecimal text data ( It consists of a hexadecimal text data generator 230 that converts it to D^),

The project information (D) created and entered by the manager from the project information management means (100) is converted into block data (Db) that can be recorded in the blockchain (BC),

More specifically,

In order to record the project information (D) created from the project information management means 100 by the manager in the first blockchain (BC1), a metadata generator ( 210);

a code data generator 220 that processes the metadata (D') created by the metadata generator 210 and converts it into encrypted code data (D");

The code data (D") encrypted by the code data generator 220 is processed so that it can be registered in the format used in the first blockchain (BC1), and converted into hexadecimal text data. It consists of a hexadecimal text data generator 230 that converts it to (D^),

The project information (D) created by the manager from the project management means (100) is converted into block data (Db) that can be recorded in the first blockchain (BC1),

The metadata generator 210, as shown in FIG. 4,

Project condition extraction module 216 that extracts and inputs project conditions (business purpose, outline, advisory group composition and field, etc.) from project information (D);

A project specific information extraction module 217 that extracts and inputs project specific information (whether or not the project will be extended, payment processing method, etc.) from the project information (D);

It consists of a project contract date extraction module 218 that extracts and inputs the contract date between the client and partners from the project information (D),

Convert project information (D) into metadata (D').

Referring to Figure 4, to explain in more detail,

The project information management means 100, in which overall project information (D) for project conclusion is created and managed by the administrator's input, generates a transaction whenever a project registration occurs.

Of course, multiple project registrations can be collected at once and processed in a batch.

For example, "On January 1, 2021, it was concluded that K2B (Partner), a patent firm, will carry out a project on analysis of the 4th industrial technology trend requested by Ewoo INC Co., Ltd. (client) for 6 months. , If the project request for a price of 50 million won is successful,

Project information (D) refers to "client (EWINC Partners) K2B Patent Firm", project conditions and period of "performing 4th industrial technology trend analysis for 6 months", and "January 1, 2021" It can be the project date, “Price: 50 million won,” and the project amount.

Additionally, data such as transaction serial number “0001” may also be included.

The metadata generator 210, which converts the project information (D) as described above into metadata (D'), has the same properties as shown in FIG. 4.

Metadata (D') is converted in the same manner as in FIG. 4, but is actually written using plain text and a delimiter.

Here, assuming that the delimiter is ";" and writing the example,

It can be expressed as "0001; 6-month 4th industrial technology trend analysis performance; 20210101; Client; Ewoo I&C Co., Ltd.; Partners; Patent Firm K2B; Price 50 million won."

The metadata (D') as described above is processed and encrypted by the code data generator 220 and converted into code data (D").

For example, this is a simple encryption:

If you encrypt "0001; 6-month 4th industrial technology trend analysis performance; 20210101; client; Ewoo I&C Co., Ltd.; partners; patent firm K2B; payment KRW 50 million",

It can be encrypted as "1112; 7 guests, worms, 5 people, 5 people, 5 people, 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 31321212; 7 people.

The encryption described above is an embodiment of the present invention, and is encrypted by adding 1 to each character to facilitate understanding of the present invention.

Meanwhile, in the first blockchain (BC1), a random data variable that can contain separate records in addition to the project information (D) record is prepared.

This is possible not only for Ethereum, the currently available virtual currency, but also for Bitcoin.

In the case of Bitcoin, OP_RETURN can be used as an arbitrary data variable.

However, the length of the variable may be limited to 40 [byte] or 80 [byte].

Meanwhile, the hexadecimal text data generator 230 allows the encrypted code data (D") created by the code data generator 220 to be registered in the format used in the first blockchain (BC1). , It processes the encrypted code data (D") and converts it into hexadecimal text data (D^).

Random data variables in the first blockchain (BC1) use hexadecimal text.

Therefore, plain text such as “i love, love.”

It is converted to "69206C6F76652C206C6F76652E".

Accordingly, as in the example of the code data (D") above,

"1112; 7 guests, worms, 5 people, 5 people, 5 people, 31321212; 31321212; 31321212; - porridge + 1,000 people, 1 person, 2 people, 5 people, 5 people, 5 people, 31321212; 31321212; 31321212; 31321212; - porridge + 1,000 people; By wealth (230),

"313131323B37AC1DC6DCAC07C81D35CC29C0B3C5C7AE31C228B3C43148D5903148BD87C120C219D57431483B33313332313231323BD07CB77DC775C5BBD2B93B2DC8FD2 Converted to “BC775C6B1C545C775C5D03137C5293BD30DD2B9B109C2A53BD2BCD5C9BC97C7743137CF01C775D22DBE45”.

At this time, during the process of generating block data (Db), the code data generating unit 230 and the hexadecimal text data generating unit 230 do not matter even if the order of operations is changed.

In other words, metadata (D') is created from project information (D), metadata (D') is converted to code data (D"), and code data (D") is converted to hexadecimal text data (D^). Finally, block data (Db) to be recorded in the first blockchain (BC1) is generated by the first project information blockchain recording means 310, or hexadecimal text data (D^) in the metadata (D') ), hexadecimal text data (D^) is converted into code data (D"), and block data (Db) can be generated.
