Description

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

The present invention relates to a project information management means using a block chain system, and more specifically, by using and distributed storage of project information created by an administrator using a dual block chain system, objectivity and transparency of project information are strengthened as well as It relates to a project information management means using a block chain system that improves security, confidentiality, and processing (storage) speed.

project is,

It is used in a variety of meanings, and refers to a unit work or project that has the character of a one-time operation, such as system development, program design, R&D plan, or construction work, which is carried out to achieve a specific purpose.

Generally, it refers to an organic and organizational plan for the development of research or new business, and refers to a learning activity for a specific goal or plan, an action plan, etc.

Projects are generally carried out in the research unit of a company or university, but in the case of large-scale research plans that are carried out according to long-term planning with a specific purpose, they are often carried out under the leadership of the state.

In particular, this is a case in which a large number of required personnel or continuous and extensive investment of funds is required.

In accordance with the nature of various projects, the conclusion of a project execution contract between a client and a partner must be accompanied by objectivity, reliability, and sometimes confidentiality.

However, at present, there is an insufficient point in maximizing objectivity, reliability, confidentiality, and security, such as simply recording the project execution contract and the work and progress on a computer or storing it in a file.

Blockchain is

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

This is essentially a form of distributed data storage technology, and it is a change list in which continuously changing data is recorded in all participating nodes, so that arbitrary manipulation by the operator of the distributed node is impossible.

The hash value is

In order to prove the identity of the copied digital evidence, it is a password-like number that abbreviates the file characteristics and is generally referred to as a 'fingerprint of digital evidence' in the investigation process.

A value obtained by mapping data having various lengths to data having a fixed length.

That is, it is a function that maps data of an arbitrary length to data of a fixed length.

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

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

Because hash functions can find duplicate records in large files, they can speed up database searches or table searches.

Accordingly, the present invention applies a block chain technology that can prevent forgery and falsification of data as a public transaction ledger by transparently recording and distributing project-related tasks in a project system that creates and manages project information. However, by using both private and public blockchains at the same time, taking advantage of their respective strengths, maximize the effectiveness and efficiency of the project system, and enhance the objectivity and transparency, reliability, confidentiality, and processing (storage) speed of project information. , to establish and provide a more systematic and robust project information management means.

Accordingly, as a prior art on project information management means using a block chain system,

As shown in (a) of Figure 7, the "project management system and project management method" of Republic of Korea Patent Publication No. 10-1841161 (hereinafter referred to as 'prior art 1'),

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

As "method, apparatus and program for providing a blockchain-based project management service" (hereinafter referred to as 'prior art 2') of Republic of Korea Patent Publication No. 10-2061448,

Acquiring project information, classifying the task of the project, determining the type of the project, selecting one or more performing subjects to perform the project based on the divided task and the type of the project A method for providing a blockchain-based project management service, comprising the step of determining, determining the task to be performed by each of the one or more execution entities, and transmitting information for managing the project to a node on a block chain will be.

As can be seen, the prior art 1 to the prior art 2 relate to a project management system, and although the present invention and the technical field are similar, there is a difference from the technical idea of the present invention.

In more detail, the present invention converts and encrypts data to be combined with a block chain in order to apply the project information created and recorded from the means for managing the project to the block chain technology, but the administrator can at times and easily By making it possible to read and sort the data combined with the block chain, as well as convert the data into a hash value, so that the hash value is also recorded on the block chain, the objectivity, transparency, reliability, and confidentiality of the management of project information are strengthened. Of course, this is to provide a management means that allows the processing (storage) speed to be improved.

Therefore, since there is a difference in the problem to be solved (objective of the invention), the solution (component) for solving it, and the effect of the invention exhibited thereby, the technical characteristics are different from the prior art 1 and the prior art 2 will do

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

First, access to the project information management means (1) using the inventor's blockchain system (▶ S100, system connection step)

The manager writes the project information (D) to be transacted with the first block chain (BC1) using the project information management means (100) (▶ S200, project information creation step)

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

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

At this time, when the block data (Db) is recorded in the first block chain (BC1) by the first project information block chain recording means (310), the first electronic money (EC1) issued from the management body is used, Conclude a transaction with the 1st special node (SN1) so that the block data (Db) is recorded in the first block chain (BC1) with approval by the authorized participant. (▶ S400, participant approval step)

The block data generation step (S300) is,

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

a project specific item extraction module 217 for extracting and inputting specific details of the project (project extension, payment processing method, etc.) from the project information (D);

It consists of; a project contract date extraction module 218 for extracting and inputting the contract date between the client and the partner from the project information (D);

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

Referring to Figure 4, in more detail,

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

Of course, it is also possible to batch-process multiple project registrations at once.

For example, "On January 1, 2021, K2B (Partners), a patent firm, concluded a project related to the analysis of technology trends in the 4th industry requested by Yiwu INC (client) for 6 months. , if the project request of “50 million won” has been completed,

Project information (D) includes "Client) Yiwu INC Partners Co., Ltd.) K2B", "Performed 4th industrial technology trend analysis for 6 months", project conditions and period, and "January 1, 2021 It can be the project date of ", the project amount of "50 million won".

In addition, data such as "0001", which is a transaction serial number, may also be included.

The metadata generator 210 that converts the project information D as described above into metadata D' has properties as shown in FIG. 4 .

The metadata D' is converted in the same manner as in FIG. 4, but is actually created using plain text and a delimiter.

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

It can be expressed as "0001; 4th industrial technology trend analysis performed for 6 months; 20210101; Client; Yiwu INC Co., Ltd.; Partners; K2B, a patent corporation; 50 million won in price".

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

For example, if it is simply encrypted,

If "0001; 4th industrial technology trend analysis performed for 6 months; 20210101; Client; Yiwu INC; Partners; K2B Patent Corporation; 50 million won in price" is encrypted,

It can be encoded as "1112; 7 worms trap stalks, 5 stinks, and breathes well ; 31321212; squeaks and squeaks; - each porridge + squeaks;

The above encryption is an embodiment of the present invention, and in order to help the understanding of the present invention, 1 is added to each character to be encrypted.

On the other hand, in the first block chain (BC1), an arbitrary data variable is provided that can contain a separate record in addition to the project information (D) record.

This is possible not only with Ethereum, the current virtual currency, but also with Bitcoin.

In the case of Bitcoin, you can use OP_RETURN as an arbitrary data variable.

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

On the other hand, the hexadecimal text data generation unit 230 may register the encrypted code data (D") created by the code data generation unit 220 in a format used in the first block chain BC1. , It processes the encrypted code data (D") and converts it into hexadecimal text data (D^).

Random data variables of the first block chain (BC1) use hexadecimal text.

Therefore, a plain text such as "i love, love."

It is converted to "69206C6F76652C206C6F76652E".

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

This hexadecimal text data is created by "1112; 7 worm worms, 5 worms, squeaky, stinky, breathing; 31321212; by part 230,

Converts to "313131323B37AC1DC6DCAC07C81D35CC29C0B3C5C7AE31C228B3C43148D5903148BD87C120C219D57431483B33313332313231323BD07CB77DC775C5BBD2B93B2DC8FD2BC775C653B1C5C545C7752BD30DD2DC8FD2BC775C653B1C545C7752BD30DD2BC8FD2BC775C653B1C545C7752BC5D227777

At this time, during the process of generating the block data Db, the code data generating unit 230 and the hexadecimal text data generating unit 230 may change the order of operations.

That is, metadata (D') is generated from project information (D), and metadata (D') is converted to code data (D") and code data (D") to hexadecimal text data (D^). Finally, block data (Db) to be recorded in the first block chain (BC1) is generated by the first project information block chain recording means (310), or hexadecimal text data (D^ ), by converting the hexadecimal text data (D^) into code data (D"), block data Db may be generated.

For example, a plain text such as "i love, love." is converted to "69206C6F76652C206C6F76652E", and the converted hexadecimal is encrypted by adding 1 to "7A317D7087763D317D7087763F" that can be converted.

On the other hand, the first project information block chain recording means ( 310) is,

a management subject electronic money transaction unit 311 in charge of transactions using the first electronic money (EC1);

Consists of; a first block chain recording unit 312 that records block data (Db) as a first block chain (BC1);

It is a transaction using a predetermined number of first electronic money (EC1) issued by a management entity that has the authority to approve the transaction and create blocks, so that the block data (Db) is recorded in the first block chain (BC1).

That is, since the block data Db is recorded in the first block chain BC1 by the first project information block chain recording means 310, confidentiality, storability, and stability of the project information D are secured, as well as processing With the improvement of (storage) speed, the efficiency of management is also improved.

More specifically,
