Description

{System for data interworking for ownership certification of data and data sharing}

The present invention relates to a data verification system, and more specifically, to a technology field that embeds a node that verifies the integrity of data in a terminal, enables copyright authentication in a non-forgery manner at the time of digital data creation, and verifies the time of initial creation of digital data in a non-forgery manner on a public blockchain.

The global digital photo and video market size is estimated to reach KRW 60.3 trillion (approximately USD 45.9 billion) in 2021.

In the 21st century, digital devices capable of taking photos and videos, such as smartphones, have increased explosively. As of 2023, the number of smartphone users worldwide will exceed 5.5 billion, and the penetration rate will exceed 70%, making smartphones a universally used personal device worldwide.

The smartphone digital photo and video market continues to grow at an annual rate of approximately 6%, and the personal photo and video trading market (stock market) is expected to grow to KRW 10 trillion globally and KRW 40 billion domestically by 2022.

Five billion digital photos and videos are taken every day, or about 1.81 trillion per year, and the number is increasing every year. 1.3 billion photos are shared daily on social media (e.g. Instagram), accounting for 6% of all photos shared online.

As various types of data are accumulated in various ways and in various places, new problems and management points that were not previously highlighted are emerging. Issues such as privacy issues such as personal information leaks, unauthorized theft and abuse of personal information, indiscriminate collection of personal information by companies, indiscriminate data collection by large companies, and unauthorized commercial use are emerging as current issues.

Some suggested methods to fundamentally prevent image copyright infringement include inserting watermarks into photos, prohibiting downloads after right-clicking on a website, reinforcing copyright notices, or inserting a DCMA Badge (a CMA Badge is a service that automatically tracks copyright and takes down websites that are found to have been used without permission when the Badge is inserted into a website). However, a strong method or solution is needed to protect individual copyrights.

In addition, as the quality of text, photos, and videos generated by AI has recently improved, the need to distinguish between processed data produced by AI and actual articles and original photos taken by people has rapidly increased.

Recently, many startups are trying out new business models to address these issues. However, records such as financial data, various certificates and credentials, health records, and preference data are mainly produced, accumulated, and managed by external organizations such as the government, financial institutions, insurance companies, and public institutions. Therefore, business is impossible without collaboration in data linkage and data joint management with companies or organizations that have de facto exclusive management rights to this data.

However, personal archives such as photos and videos stored on personal terminals or smartphones not only have great potential value, but are also considered to be relatively easier to manage than other content where management authority is shared or delegated to institutions and companies, as individuals have the authority to manage and dispose of them.

For example, there is also a prior patent document on a method for managing copyright of data through blockchain, “Copyright Management Method and System (Registration No. 10-2144302, hereinafter referred to as Patent Document 1).”

In the case of Patent Document 1, a digital content copyright management method includes receiving a copyright processing request, configuring a copyright management transaction according to the copyright processing request, and storing the copyright management transaction in a blockchain for processing, wherein the blockchain is stored in all blockchain devices. Reliable and secure processing of the copyright management transaction can be implemented.

In addition, there exists a “copyright management system for non-digital works based on blockchain (registration number 10-1981699, hereinafter referred to as patent document 2).”

In the case of Patent Document 2, a copyright holder device that requests registration of a copyrighted work on a server for copyright management, a server that receives a registration request for the copyrighted work and information related to the copyrighted work from the copyright holder device, performs registration of the copyrighted work in response to the registration request, and generates an ID matching the copyrighted work upon registration, and records the generated ID and information related to the copyrighted work on a blockchain, and is characterized in that the copyrighted work is a non-digital copyrighted work.

In addition, there is also “The first copyright owner authentication system and method using blockchain (Registration No. 10-2319006, hereinafter referred to as Patent Document 3).”

In the case of Patent Document 3, the method includes: a copyright terminal which inputs minimum unit information on an original work and generates a request signal for generating a unique ID of the copyright holder; a copyright management server which receives a request signal for generating a unique ID, generates unique ID information depending on whether the unique ID is authenticated, determines whether the minimum unit information has the distinctiveness and similarity when the minimum unit information is received, and generates a hash value including time information of the minimum unit information depending on the determination result, and stores the generated hash value in a blockchain while connected to a blockchain network; and an authentication server which receives information on a unique ID and minimum unit information from the copyright management server and performs authentication of the received information.

For example, personal archives such as photos and videos that are continuously accumulated on smartphones can be commercialized relatively easily by 1) providing a new service model targeting personal archives stored on smartphones, and 2) strengthening indications of personal copyright and ownership for media contents such as photos and videos produced by individuals and shared on SNS, thereby eliminating the possibility of copyright infringement and unauthorized use, and granting legitimate rights to the data produced by individuals and enabling it to be traded for a fair price.

Faced with these changing environments and the emergence of new requirements, it is necessary to develop a system that distinguishes between processed content and original content, grants individuals fair rights to the data they produce, and allows it to be traded for fair compensation.

In order to verify personal data, it is common to use public blockchains, and in order to objectively and transparently verify blockchain data, a method is used where everyone can access the blockchain at all times and transparently verify the data.

However, general public blockchains (mainnets) have the disadvantage of slow data processing speed, requiring payment of blockchain usage fees, and being available only online.

On the other hand, in the case of the present invention, a personal blockchain is provided that first records are made on a conceptualized plurality of nodes (e.g., personal blockchain) built into a smartphone.

The advantages of providing a personal blockchain formed with built-in private nodes include i) real-time registration of new copyright information, ii) minimization of copyright management costs with no usage fees, iii) usability even in offline states when the network is disconnected, and iv) constant storage of supporting data for legal disputes.

Additionally, in order to secure the public nature of data stored in personal blockchains, it is possible to link with and utilize external public blockchains.

A data linkage system for proving ownership of data and externally sharing data according to the present invention comprises a personal loading unit (100), a node action unit (200), and an external sharing unit (300).

First, the personal loading unit (100) is provided on the user's terminal (1), is composed of N nodes, receives digital data (10) generated from the user's terminal (1), and registers the ownership and copyright of the digital data (10).

The user's terminal (1) may include any electronic equipment capable of producing content such as photos and videos and creating data such as documents, such as smartphones, tablet PCs, and personal computers.

In the case of digital data (10), it may correspond to i) data accumulated/stored in personal archives such as smartphones, such as images, videos, and other personal works, and ii) data for which personal management rights are limited or management rights are shared with external organizations or companies, such as posts or photos posted on SNS.

In addition, iii) it may be data that is personal data, such as personal information, financial information, and medical information, but whose management agency has been effectively delegated to an organization or company outside the individual.

Specific examples of digital data (10) include personal financial records, health records, preference records, purchase records, photographs, videos, documents such as personal contracts, various certificates and certifications, etc.

Ownership and copyright of digital data (10) may correspond to copyright and ownership information for digital data (10), and may correspond to, for example, information on the time of creation of content, information on the time at which digital data (10) was stored, etc.

In the case of the personal loading unit (100) and the node action unit (200), they can be said to be private applications that operate within a smartphone.

The node action unit (200) shares information on registered digital data, ownership information on digital data, and copyright information on digital data from the personal loading unit (100) to N nodes.

The stages of the distribution flow of copyright/original author information in digital data (10) through the personal loading unit (100), node action unit (200), and external sharing unit (300) may correspond to Table 1.

step Step Description Detailed Description 1 Content Creation Create new images/videos using a camera phone, etc. 2 Create and store private credentials Create and store on your personal blockchain built into your phone 3 Create and store public credentials Create and store on a public blockchain selectively linked to the app 4 Automatic exposure of public authentication information on SNS When sharing on SNS, information stored in the public blockchain is exposed in the post.

For example, if a copyright infringement or dispute arises regarding digital data, steps 1 and 2 or steps 3 and 4 can be used as evidence in legal proceedings.

The external sharing unit (300) shares digital data (10) stored and shared in N nodes with multiple external nodes.

In the case of multiple external nodes, it may correspond to an external blockchain (30).

External blockchains can issue NFTs and serve as external authentication for copyright/ownership.

It is desirable that there be no limitations on the type and size of the external multiple nodes, i.e. external blockchains.

The personal loading unit (100), node action unit (200), and external sharing unit (300) can store information and digital data (10) using the CPU, memory, storage space, and database provided within the terminal (1).

In addition, for example, the built-in personal loading unit (100) and node action unit (200) can be driven on a photo album (or camera) app, and when a new image or video is added, the copyright basic information and hash value of the corresponding digital data (10) can be stored.

The personal loading unit (100) of the data linkage system for data ownership proof and external data sharing according to the present invention is composed of conceptually distinct nodes, each of which is formed by N distinct nodes.

For N nodes, it consists of at least 2 nodes, but can consist of more than 2.

The personal loading unit (100) of the system may correspond to a personal blockchain formed by a private node built into the terminal (1), and may have differences as shown in Table 2 compared to the generally utilized mainnet structure.

The information receiving unit (120) receives ownership information and copyright information for digital data (10) received from the data receiving unit.

The information receiving unit (120) can receive information on the copyright and ownership at the time of creation of primary works such as photos, videos, documents, and texts produced by the terminal.

Ownership information and copyright information in digital data (10) may include information about the time of creation of the digital data (10) or information about the time of loading the digital data (10) into the personal loading unit (100).

The data receiving unit (110) may automatically or according to the user's choice (e.g., user operation) call the built-in personal blockchain to receive the users' digital data (10) whenever digital data (10) is generated in the terminal.

The node action unit (200) of the data linkage system for data ownership proof and external data sharing according to the present invention is configured to include an information sharing unit (210), a verification unit (220), and a data storage unit (230).

In the case of the information sharing unit (210), the digital data (10) and ownership information and copyright information stored in the data storage unit are shared among N nodes.

In the case of copyright information, it may correspond to the creator's rights information for the work of digital data (10).

In the case of copyright information, it may correspond to, for example, author name information, work title information, publisher information, work size information, classification information, work structure information, work genre information, work publication date information, work registration date information, etc.

In the case of ownership information, this may include, for example, owner name information, owner location information, and owner change information.

The verification unit (220) is configured to mutually verify digital data (10), ownership information, and copyright information through N nodes.

The data storage unit (230) stores digital data (10) and ownership information and copyright information shared through the information sharing unit (210) in each of the N nodes.

In addition, the data storage unit (230) is stored in each of the N nodes built into the terminal (1), and may not require separate payment conditions for data storage.

The data storage unit (230) can be selectively operated when new photos or videos are added, and the amount of internal database usage of the terminal (1) can be minimized through selective operation.

The data storage unit (230) operates when new digital data is stored to store the hash value, copyright, and original author information of the digital data (10), and can operate to use hardware resources and internal storage of a terminal (e.g., a smartphone).

In addition, the information stored in the data storage unit (230) can provide a backup function in response to terminal failure, loss, malfunction, etc., and can periodically back up the digital data (10) and the copyright information and ownership information of the digital data (10) to an external backup service to minimize the possibility of content loss.

For backup of digital data (10), a server (not shown) for an external backup service may be provided.

The verification unit (220) of the data linkage system for proving ownership of data and external sharing of data according to the present invention is configured to include a data verification unit (221) and an information verification unit (222).

The data verification unit (221) verifies digital data (10) stored in N nodes through each of the N nodes.

Verification can be made possible by comparing each other's matching for digital data (10).

The information verification unit (222) verifies the ownership information and copyright information stored in each of the N nodes by cross-matching and comparing the N nodes.

It is possible to verify the ownership information and copyright information by comparing them with each other.

The external sharing unit (300) of the data linkage system for proving ownership of data and externally sharing data according to the present invention is configured to include a data sharing unit (310), an authentication information generation unit (320), and an authentication information sharing unit (330).

The data sharing unit (310) shares digital data (10) stored from the terminal (1) with multiple external nodes according to the user's request.

The authentication information generation unit (320) selectively generates authentication information based on ownership information and copyright information.

In the case of authentication information, it may correspond to information for authentication of public copyright and ownership of digital data (10).

The authentication information may also correspond to information that proves ownership for issuing NFTs (Non-fungible tokens) by multiple external nodes.

The authentication information sharing unit (330) shares and stores authentication information among multiple nodes.

In the case of authentication information stored through the authentication information sharing unit (330), it can be shared and stored in N nodes and also shared and stored in multiple nodes.

The authentication information generation unit (320) of the data linkage system for data ownership verification and external data sharing according to the present invention generates authentication information from ownership information and copyright information on digital data (10), and allows the authentication information generated through the authentication information generation unit to be shared with multiple external nodes and N nodes, respectively.

External multiple nodes and N nodes are linked and can be linked and utilized to secure the integrity of N nodes and the public nature of data stored in N nodes.

Multiple nodes (e.g. external public blockchains) can act as external authentication for NFT issuance, copyright, and ownership, and can act as transaction intermediaries by linking with external markets.

For content (data) provided to multiple nodes (external public blockchains), ownership, copyright, and content (digital data) creation time can be authenticated on the external public blockchain based on the data stored in N nodes.

The external sharing unit (300) of the data linkage system for data ownership proof and external data sharing according to the present invention is networked with a plurality of external nodes, shares digital data (10) verified through an information verification unit (222) from N nodes, and enables sharing through mutual matching of digital data (10) between a plurality of nodes and the N nodes.

In the case of the external sharing unit (300), N nodes and multiple external nodes are linked and networked to share information among themselves.

A representative user scenario for the use and sale of digital data according to the present invention may correspond to Example 1.

[Example 1]

i) Upload a photo taken with a terminal (smartphone) to the personal loading unit (100) and register the copyright and ownership.

ii) After one week, issue the photo as an NFT on an external blockchain, and upload the photo to Instagram with copyright/ownership information (copyright notice) included. At this time, you can watch in-app ads to earn external blockchain usage fees and pay for the usage fees.

iii) Someone on Instagram expresses interest in purchasing the photo and sells it on the marketplace.

iv) After viewing the thumbnails of my photos published on the marketplace, I express my intention to purchase the entire content from the AI company, provide the AI company with the right to use the photos, and receive compensation.

Each of the N nodes of the data linkage system for data ownership proof and external data sharing according to the present invention receives transaction information of digital data (10) and allows the transaction information to be shared with each other.

A plurality of nodes compare the transaction information of the digital data (10) with the digital data (10) to confirm whether the transaction information of the digital data (10) and the digital data match each other.

In the case of transaction information of digital data (10), it may correspond to the work status change history for digital data (10).

For example, it may correspond to inquiry, update, additional work, change of ownership, etc. of digital data (10).

Transaction information can also be mutually verified and stored through matching of N conceptualized nodes, and transaction information can also be mutually shared between N nodes and multiple external nodes.

In addition, when sharing personal digital data (10) such as photos/videos on SNS (Social Network Service), the hash value and copyright information recorded in N nodes and the original author information can be exposed, or NFT can be issued through multiple external nodes and copyright authentication information can be exposed based on the NFT.

For example, when sharing photos and videos from a photo album on SNS, it is possible to display copyright and original author information, and when sharing on SNS, information stored in N nodes can be exported, or photos, videos, and information stored in N nodes can be stored and recorded on multiple external nodes, and information from multiple external nodes can be exported to SNS.

In addition, the data verification system for verifying ownership of personal data according to the present invention may include a management app (20) corresponding to an app for managing digital data (10).

The management app (20) can provide an app that authenticates and proves the copyright and ownership of photos, videos, documents, etc. produced by individuals within the terminal by linking with the personal loading unit (100) and the node action unit (200) through API communication, thereby enabling sharing and trading with the outside.

In addition, the management app (20) can be linked with an external marketplace (not shown) to enable content corresponding to digital data (10) to be issued and traded as NFT.

Users can trade with traders (2) for digital data (10) through external marketplaces (not shown), and may also be able to trade with content creators.

If data matching between nodes is not achieved through an event regarding a transaction that occurred in one of the N nodes, the verification unit (220) selectively removes information on digital data (10), copyright information, and ownership information that are not sourced from the personal loading unit (100), node action unit (200), and external sharing unit (300), and it is desirable to achieve matching of data between nodes.

In the case of N nodes, for example, if there are 1, 2, …, n nodes, a leading node is selected from among multiple nodes to perform verification, information is shared through the leading node, and thereafter, verification of the event can be performed through multiple preset nodes.

In this regard, the node action unit (200) may include a leader selection unit (240) that selects a leading node.

Election for the leading node follows a preset election method.

For the leading node, it is desirable to be elected according to an election method set by a plurality of preset nodes or a preset election method for N nodes.

Additionally, the leader selection unit (240) may include a leading verification unit (241) that enables the selected leader to perform verification on the occurrence of an event.

In addition, it includes a scattering unit (242) in which information about an event verified through a leading verification unit (241) is shared by a plurality of nodes preset by a leader node, and an event verification unit (243) in which event information shared to each node through the scattering unit (242) is verified by each node.

In the case of the leading verification unit (241), a leading node selected according to a preset election method performs verification of the occurrence of an event (here, verification of the occurrence of an event may correspond to copyright information, ownership information of digital data, and transaction information of digital data), and if there is no agreement on the occurrence of an event with the transaction information of digital data, the transaction for which there is no agreement is selectively removed by the leading node.

After verification of the occurrence of an event by the leading node, the scattering unit (242) shares a transaction corresponding to information about the event with multiple nodes.

Through the event verification unit (243), each of the plurality of nodes set in advance is allowed to proceed with subsequent transaction verification through mutual verification between the nodes, and mutual verification is performed to determine whether information about digital data shared by each node and an event occurring in transaction information of the digital data are consistent, and if an event occurring in digital data and an event occurring in ownership information or copyright information are not consistent, the corresponding transaction can be selectively removed.

The scope of the rights of the present invention is determined by the matters described in the claims, and the parentheses used in the claims are not described for optional limitation, but are used to indicate clear elements, and the description within the parentheses should also be interpreted as essential elements.
