Description

Profit distribution method and system according to the distribution of pseudonymous information based on blockchain

The present invention relates to a method and system for distributing revenue according to the distribution of personal information, and more particularly, to a method and system for distributing revenue generated from the distribution of pseudonymized information, which is personal information processed under pseudonymation, based on a block chain. .

In the past, personal information collected with the consent of the information subject was pseudonymized (performed de-identification measures) so that the original owner of the information could not be identified. A problem arises that the revenue generated from distribution cannot be distributed to the information subject who provided the information.

In other words, in the case of pseudonymous information for which de-identification measures have been performed, even if revenue is generated from the sale/distribution of pseudonymous information, it is not possible to know who the original data subject of the pseudonymous information for which revenue was generated, so that the revenue cannot be distributed to the data subject. will be.

Therefore, even in the case of selling/distributing collected personal information under a pseudonym, it is required to identify a data subject of pseudonymized information that is pseudonymized personal information and to find a way to decompose the generated profits.

For example, the processor 130 adds a data ID (ex. OxD11) and a pseudonym processing ID generated while generating pseudonym information to pseudonym information in which region, block chain account, and consent information are combined, to the block chain network. can be recorded

In addition, the processor 130, the pseudonymized ID recorded in the block chain network in the non-pseudonymized personal information (including name, mobile phone number, etc.) and the data ID generated while the personal information is transmitted to a separate storage means (ex OxD21) may be added and stored in a separate storage means separated from the storage unit 120 .

Here, the pseudonymization ID may be a hash value that is output by combining at least two or more of personal information according to a rule set for each operator or service, inputted into a hash function.

Also, at this time, the processor 130 may generate a pseudonymization ID including unique information according to a business operator or service supported by the processor 130 , even with the same processor 130 , and add it to the pseudonym information.

That is, the processor 130 pseudonymizes the collected personal information in a specific service supported by the processor 130 among a plurality of services provided by a specific operator.

And the information recorded in the block chain network includes data IDs (ex. OxD11, OxD21) for each block chain account (ex. OxA1), parent data IDs (ex. OxD1) and other information (ex. OxD1), which are previously added and accumulated data IDs ( notes) may be included.

6 is a diagram provided to explain a process of combining each pseudonym information processed by another service of the same operator according to an embodiment of the present invention.

Referring to FIG. 6 , in this revenue sharing method, through the processor 130 , each pseudonym information processed by different services within a specific business operator may be combined.

For example, the processor 130 may generate the first combined pseudonym information by performing a combination between each pseudonym information processed by different services within a specific business operator (S610), and in this case, each pseudonym Based on each pseudonymization ID added to the information, a new pseudonymization ID may be generated and added to the first combined pseudonym information, and the generation history of the first combined pseudonymous information may be recorded in the block chain transaction ledger (S620).

That is, the processor 130 may not only use information collected through a specific service, but may also use information collected through other services, and may generate more various information through combination of information to provide information to various operators or services. You can distribute/sell information and generate revenue through it.

For example, the processor 130 may include pseudonym information in which the region, BC account and data ID are combined with the pseudonym processing ID, the house classification information in which the information subject resides in the pseudonym processing ID, and pseudonym information in which the BC account and data ID are combined. may be combined to generate the first combined pseudonym information.

In this case, in the first combined pseudonym information, a new pseudonymization ID (A41) is added instead of the two existing pseudonymization IDs (A1, A31), and a new data ID (OxD41) is generated and added.

And here, the information recorded in the blockchain network may include data IDs (ex. OxD41) and parent data IDs (ex. OxD11, OxD21) and other information (memo) for each blockchain account (ex. OxA1). .

7 to 8 are diagrams provided to explain a process of combining each pseudonym information processed by another operator according to an embodiment of the present invention.

Referring to FIGS. 7 to 8 , in this revenue sharing method, through the processor 130 , each pseudonym information processed by different operators may be combined.

Specifically, the processor 130 may convert each pseudonym information into a CSV (Comma Separated Value) file when combining each pseudonym information processed by different operators is performed (S710).

For example, the processor 130 adds a data ID (ex. OxD50) added when a CSV file is created to pseudonym information including name, mobile phone number, region and house classification and identification information (#) of the CSV file. So, you can create a CSV file.

Here, the information recorded in the blockchain network may include data ID (ex. OxD50) and parent data ID (ex. OxD41, OxD42, OxD43) and other information (memo) for each blockchain account (ex. OxA1). In addition, the parent data ID refers to an accumulated data ID in which two or more pseudonym information is combined so that the name, mobile phone number, region and house classification are included in the pseudonym information.

And the processor 130 generates second combined pseudonym information by combining the respective CSV files, and when the second combined pseudonym information is generated, based on the data ID added to each pseudonym information converted into a CSV file, new A data ID may be generated, added to the second combined pseudonymous information, and the generation details of the second combined pseudonymous information may be recorded in the block chain transaction ledger (S720).

That is, when the processor 130 supporting the operator A and the processor 130 supporting the operator B provide a CSV file, respectively, the processor 130 supporting the operator A or the processor 130 supporting the operator B respectively When the second combined pseudonym information is generated by combining each CSV file of The generation of the second combined pseudonym information can be recorded in the block chain transaction ledger, at this time, the information recorded in the block chain network is data ID (ex. OxD70) and parent data ID for each block chain account (ex. OxA1) (ex. OxD50, OxD60) and other items (memo) may be included.
