Description

[Technical Field]

[0001] This invention relates to a business information type digital information guard and trading system that protects personal information and other data that is difficult to manage from high-level cyber attacks, mainly on-chain, against risks such as high-level cyber attacks that exceed normal levels, severe natural disasters, or physical attacks that are expected in the future, while also making it possible to effectively utilize (basically) small amounts of data linked to personal information and generate revenue. In this specification, "system" refers to a computer system that is configured by combining elements such as computers, other electronic devices, software, communication networks, and data, and that specifically realizes software-based information processing using hardware resources. [Background technology]

[0002] Conventionally, distributed encryption technology such as blockchain has been used as an example of a measure to protect data from common cyber attacks. However, in the future, we can expect to see more sophisticated cyberattacks (by state actors or actors combining state and non-state actors) that exceed the usual level, such as quantum computer-based cryptography and EMP attacks, which will be discussed later. These sophisticated cyberattacks aim to leak, alter, erase, or destroy digital assets (confidential information such as personal information and national security-related information, control modules for important functions, currencies such as stablecoins, digital currencies, and digital securities, and rights such as contracts). This makes it important to protect digital assets from high-level cyber attacks.

[0003] Digital assets that are subject to high-level cyber attacks are thought to cover a wide range of areas, including personal information (account information) and personal asset information held by financial institutions, confidential information such as personal information and national security-related information held by large corporations and government agencies, confidential internal information, important contracts and designs, control modules and data, and information related to lifelines.To date, there have been no services (especially for private use) that can provide a high degree of protection against high-level cyber attacks, and in fact, no services with quantum computer cryptanalysis resistance (such as PQC (Post-Quantum Cryptography)) have been put into practical use. Summary of the Invention [Problem to be solved by the invention]

[0004] Furthermore, when it comes to personal information, confidential corporate information, or state-level confidential information, the system is subject to very strict restrictions on the evacuation of digital assets. For example, if a business entity other than the individual manages digital assets, the individual's consent is required. However, in reality, it is difficult to obtain consent from the individual for all digital assets that may be subject to management. This makes digital asset management limited and complicated.

[0005] Therefore, the inventors of the present invention have considered and examined measures to strongly and efficiently protect important information such as secret / classified information and personal information from high-level cyber attacks and physical destruction, and to restore important information without it being stolen by third parties even if it is subjected to cryptographic analysis by a quantum computer or an EMP attack, or measures to make it impossible for third parties to analyze the management information even if it is stolen by a third party.First, the inventors have considered and examined the preservation processing of backup data for internal systems, etc., which is carried out periodically in batches.

[0006] However, among the data that constitutes digital assets that need to be preserved, there is a huge amount of small-volume data linked to personal information. Unlike backup data held by corporate systems, small-volume data linked to personal information often requires real-time data preservation from the perspective of convenience (in the event of system destruction, in order to quickly restore the system, even a backup structure that allows for database-like processing is desirable; in other words, a function that realizes storage-like processing with data preservation functionality is desirable).

[0007] Furthermore, personal information is subject to strict legal regulations from the perspective of protection, and there is a strong need to further strengthen defenses against external cyber attacks in order to preserve small amounts of data linked to personal information.

[0008] Furthermore, there is a wide variety of data linked to personal information, and it is desirable to preserve the data in a variety of forms. Data linked to personal information in small units that do not exceed the block size can be saved to a blockchain, but as mentioned above, blockchains such as public chains cannot cut the chain that connects the blocks. When saving data to a blockchain, even if the data itself is subjected to a cyber attack, or as an application of this, information that exceeds the blockchain's block size is recorded in a distributed file function, with only the management information recorded on the block side, but even if this data itself is subjected to a cyber attack, it must be managed as meaningless data that is not recognized as personal information (including important information), and it must be made impossible to restore the original personal information as is.

[0009] Therefore, the inventors of the present invention have further considered and examined measures that can preserve digital assets, which are (basically) small amounts of data linked to personal information, in real time, strongly and efficiently protect important information such as confidential information and personal information from high-level cyber attacks and physical destruction, and restore important information without it being stolen by third parties even if it is subjected to cryptographic analysis using a quantum computer or an EMP attack, or that make it impossible for a third party to restore the management information even if it is stolen by a third party.

[0010] Incidentally, among data linked to personal information, information that does not identify the individual can be useful to the individual and third parties. For example, big data, which is information collected from electronic medical records from which information that identifies the individual has been removed, can contribute to the analytical needs of doctors, researchers, pharmaceutical companies, and others for the purpose of advancing medical care in areas such as treatment and drug development, and it is believed that patients and doctors can receive compensation for providing the information that does not identify the individual. Therefore, it is believed that by making it possible to collect such useful information more efficiently and by enabling the individual in question to monetize the information by selling it to third parties without any information that could identify the individual, it will be possible to make effective use of the information without any information that could identify the individual.

[0011] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a business-information type digital information guard and trading system that can preserve digital assets consisting of (basically) small amounts of data linked to personal information in real time, strongly and efficiently protect important information such as confidential information and personal information from high-level cyber attacks and physical destruction, restore important information without it being stolen by third parties even if it is subjected to cryptographic analysis using a quantum computer or an EMP attack, or make it impossible for third parties to restore the management information even if it is stolen by a third party, and make it possible to effectively utilize (basically) small amounts of data linked to personal information and generate profits.

DETAILED DESCRIPTION OF THE INVENTION

[0039] Before describing the embodiments, the circumstances under which the present invention was derived and the effects of the present invention will be described. Conventionally, distributed encryption technology such as blockchain has been used as an example of a measure to protect data from common cyber attacks. However, in the future, we can expect to see more sophisticated cyberattacks (by state actors or actors combining state and non-state actors) that exceed the usual level, such as quantum computer-based cryptography and EMP attacks, which will be discussed later. These sophisticated cyberattacks aim to leak, alter, erase, or destroy digital assets (confidential information such as personal information and national security-related information, control modules for important functions, currencies such as stablecoins, digital currencies, and digital securities, and rights such as contracts). This makes it important to protect digital assets from high-level cyber attacks.

[0040] Digital assets subject to high levels of cyberattacks Digital assets that are subject to high-level cyber attacks are thought to cover a wide range of areas, including personal information (account information) and personal asset information held by financial institutions, confidential information such as personal information and national security-related information held by large corporations and government agencies, confidential internal information, important contracts and designs, control modules and data, and information related to lifelines.To date, there have been no services (especially for private use) that can provide a high degree of protection against high-level cyber attacks, and in fact, no services with quantum computer cryptanalysis resistance (such as PQC (Post-Quantum Cryptography)) have been put into practical use.

[0041] Furthermore, when it comes to personal information, confidential corporate information, or state-level confidential information, the system is subject to very strict restrictions on the evacuation of digital assets. For example, if a business entity other than the individual manages digital assets, the individual's consent is required. However, in reality, it is difficult to obtain consent from the individual for all digital assets that may be subject to management. This makes digital asset management limited and complicated.

[0042] Therefore, the inventors of the present invention have considered and examined measures to strongly and efficiently protect important information such as secret / classified information and personal information from high-level cyber attacks and physical destruction, and to restore important information without it being stolen by third parties even if it is subjected to cryptographic analysis by a quantum computer or an EMP attack, or measures to make it impossible for third parties to analyze the management information even if it is stolen by a third party.First, the inventors have considered and examined the preservation processing of backup data for internal systems, etc., which is carried out periodically in batches.

[0043] However, among the data that constitutes digital assets that need to be preserved, there is a huge amount of small-volume data linked to personal information. Unlike backup data held by corporate systems, small-volume data linked to personal information often requires real-time data preservation from the perspective of convenience (in the event of system destruction, in order to quickly restore the system, even a backup structure that allows for database-like processing is desirable; in other words, a function that realizes storage-like processing with data preservation functionality is desirable).

[0044] Furthermore, personal information is subject to strict legal regulations from the perspective of protection, and there is a strong need to further strengthen defenses against external cyber attacks in order to preserve small amounts of data linked to personal information.

[0045] Furthermore, there is a wide variety of data linked to personal information, and it is desirable to preserve the data in a variety of forms. Data linked to personal information in small units that do not exceed the block size can be saved to a blockchain, but as mentioned above, blockchains such as public chains cannot cut the chain that connects the blocks. When saving data to a blockchain, even if the data itself is subjected to a cyber attack, or as an application of this, information that exceeds the blockchain's block size is recorded in a distributed file function, with only the management information recorded on the block side, but even if this data itself is subjected to a cyber attack, it must be managed as meaningless data that is not recognized as personal information (including important information), and it must be made impossible to restore the original personal information as is.

[0046] Therefore, the inventors of the present invention have further considered and examined measures that can preserve digital assets, which are (basically) small amounts of data linked to personal information, in real time, strongly and efficiently protect important information such as confidential information and personal information from high-level cyber attacks and physical destruction, and restore important information without it being stolen by third parties even if it is subjected to cryptographic analysis using a quantum computer or an EMP attack, or that make it impossible for a third party to restore the management information even if it is stolen by a third party.

[0047] Incidentally, among data linked to personal information, information that does not identify the individual can be useful to third parties. For example, big data, which is information collected from electronic medical records from which information that identifies the individual has been removed, can contribute to the analytical needs of doctors, researchers, pharmaceutical companies, etc., with the aim of advancing medical care in areas such as treatment and drug development, and it is believed that patients and doctors can receive compensation for providing the information that does not identify the individual. Therefore, it is believed that by making it possible to collect such useful information more efficiently and by enabling the individual in question to monetize the information by selling it to third parties without any information that could identify the individual, it will be possible to make effective use of the information without any information that could identify the individual.

[0048] Consideration and examination of the peculiarities of real-time digital asset guard service provision systems The inventors of this invention have repeatedly considered and examined the construction of a storage function that enables data deletion for blockchain ledgers (in the future, they envision a GRID-compatible DB (in-memory data grid: a database structure constructed in memory) that will consolidate multiple scattered computer resources and treat them as a single large-scale computer), and in the process have derived a real-time preservation type digital asset guard service provision system.

[0049] However, the inventors of the present invention have conceived of configuring a real-time preservation type digital asset guard service provision system that serves as the basis for managing data linked to personal information and that has the functionality to satisfy the requirements for third-party opposition. It is impossible to meet third-party protection requirements, including those for managing personal information, simply by using blockchain. Even if it were possible to manage personal information using blockchain, it would be necessary to ensure that the protection of personal information (guaranteeing 100% data retention) could withstand evolving cyberattacks. However, there are a wide range of anticipated cyberattacks, including quantum computer cryptography, ransomware via users, and internal crimes.

[0050] Therefore, the inventors of the present invention have conceived a real-time preservation type digital asset guard service provision system that combines polynomial secret sharing encryption processing with a processing method based on bidirectional agreement between the parties to the contract (which complements polynomial secret sharing encryption processing), thereby preserving data while simultaneously preventing analysis of the data preservation address and index information, thereby realizing PQC (post-quantum cryptography) and solving the above-mentioned issues regarding the preservation of personal information.

[0051] According to the real-time preservation type digital asset guard service provision system, in the management of personal information, the mosaicization of data using polynomials and the polynomial secret sharing encryption process that renders the data meaningless are made irreversible processes, and by cutting the index information that records the management destination of the meaningless information, it is possible to sever the link with the information actually managed and make it equivalent to the information being deleted, which is thought to make it possible to manage personal information in a form that is not personal information.

[0052] This nullified information cannot be copied by anyone other than an authorized person (a person who has formed the agreement information through a processing method based on a two-way agreement on data preservation), and since it is possible to lock certain rights based on the specified content, it is considered to meet the requirement for third-party protection. This will enable data management information linked to personal information on-chain to be linked to multiple chains.

[0053] Consideration and examination of the relationship between real-time digital asset guard service provision system and data linked to personal information The inventors of the present invention have considered having data linked to personal information reside in the upper layer of the real-time preservation type digital asset guard service providing system, and have considered having the real-time preservation type digital asset guard service providing system function as a storage (auxiliary storage device) that preserves data linked to personal information in real time. The real-time secure digital asset guard service provision system will be built with multiple private or consortium blockchains and distributed file management functions. Data in the blockchain and distributed file management function is rendered meaningless in a mosaic format using a processing method based on polynomial secret sharing encryption processing and bidirectional agreement between the parties to the contract. Management information for these data is managed as index information by black box concealment processing.

[0054] Consideration and examination of two forms of business-type information that constitutes data linked to personal information The inventors of the present invention broadly classify business information, which is data linked to personal information, into information for managing and executing processing based on a distributed program contract, and other business information type digital information. In this application, the inventors have considered and examined business information type digital information, out of the two types of business information mentioned above.

[0055] Business information type digital information Business information type digital information is not divided and managed internal information in business information type digital information, but Type We thought about dividing and managing all digital information. The business information type digital information is configured to have, for example, a data area. The idea was to have personal information or some other important information set in the data area. We thought that business-type digital information could be applied to medical record resale services, etc.

[0056] The inventors of the present invention have considered splitting and managing internal information such as personal information and important information. Specifically, the inventors have considered nullifying personal information using polynomial secret sharing encryption processing and a two-way agreement method in a real-time security-type digital asset guard service providing system, sorting it into multiple points, and managing it in a split manner. Furthermore, the inventors have considered encrypting index information and recording it in the security point sorting destination information management means of the real-time security-type digital asset guard service providing system.

[0057] Consideration and examination of managing medical records as business-type digital information Medical information includes information linked to individuals in medical records. In the medical field, doctors generally use electronic medical records, which are records of a patient's medical treatment, each time they examine a patient. In such cases, medical information including electronic medical records is used only by a specific doctor for examining the patient and is not publicly available. Therefore, the inventors of the present invention have considered creating medical information, including electronic medical records, as business-type digital information with fixed original information, based on the electronic medical records of a specific hospital. Furthermore, the original information linked to individuals in medical information, including electronic medical records, is preserved as meaningless information in a real-time preservation type digital asset guard service provision system. In the medical field, clinical trial data may be required by an unspecified number of doctors and research institutions for the development of treatments and drugs. In such cases, when using medical information including electronic medical records, it becomes necessary to exclude personal information. Therefore, the inventors of this case came up with the idea of ​​creating liquid business-type digital information that uses medical information, including electronic medical records, by deleting any information that could identify individuals and processing it into information that makes it impossible to identify individuals, and that has the property of allowing the data to be referenced and moved. In addition, in the medical field, doctors and medical institutions that can provide treatment are specified, and there are cases where medical information, including electronic medical records, needs to be provided to those specified doctors and medical institutions with the patient's consent. Therefore, the inventors of this case came up with the idea of ​​using medical information, including electronic medical records, to create user-restricted business-type digital information that would allow data to be viewed and moved, with users limited to specific certified doctors and medical institutions.

[0058] The inventors then considered generating liquid business information digital bond tokens and user-restricted business information digital bond tokens to enable trading in the market for liquid business digital information and user-restricted business digital information, and selling them on the business information digital information trading market.

[0059] In addition, the inventors have conceived a system in which, when liquid business information type digital claim tokens and user-restricted business information type digital claim tokens are traded in the business information type digital information trading market and rights are exercised using the claim tokens at the time of liquidation, the original information linked to individuals that is preserved as meaningless information in the real-time preservation type digital asset guard service provision system is restored, and liquid business type digital information and user-restricted business information type digital information are created using the restored original information.

[0060] In addition, as a way to effectively utilize personal attribute information that does not identify individuals, the inventors considered creating business information-type digital information for personal attribute information trading that does not include original information and consists only of information that does not identify individuals, and selling it in the business information-type digital information trading market.

[0061] Furthermore, in order to stimulate trading of liquid business information type digital claim tokens and user-restricted business information type digital claim tokens offered for sale in the business information type digital information trading market and to enable potential purchasers to efficiently obtain useful information, the inventors have conceived of a system in which potential purchasers can specify search items for the personal attribute information they desire in the business information type digital information trading market, extracting user-restricted business information type digital claim tokens that have personal attribute information that matches the search items, and contracting the extracted liquid business information type digital claim tokens and user-restricted business information type digital claim tokens, and matching the claim tokens and business information type digital information for personal attribute information trading with the purchase requests of potential purchasers at the time of liquidation.

[0062] Furthermore, liquid business information type digital information, user-restricted business information type digital information, and business information type digital information for personal attribute information trading will be equipped with an encrypted unified ID linked to an individual, and personal link information equipped with the encrypted unified ID will be created. Prior to a prospective purchaser in the business information type digital information trading market inputting the personal attribute information they desire, the encrypted unified ID equipped in the personal link information will be used to settle liquid business information type digital claim tokens and user-restricted business information type digital claim tokens that are being offered on different markets by personal origin information management businesses, and at the time of liquidation, groups of claim tokens and business information type digital information for personal attribute information trading will be sorted so that they can be searched for by data linked to an individual. However, in order to prevent the identification of non-individual traders, when a non-individual trader specifies a search item for personal attribute information about the individual, the encrypted unified ID associated with the individual will be converted into an ID that is different for each trader and presented to the non-individual trader.

[0063] The inventors also considered having the seller pre-set the number of times that purchasers of liquid business information digital bond tokens and user-restricted business information digital bond tokens purchased in the business information digital information trading market can exercise rights such as reference rights, and invalidate the bond token when the number of times the rights can be exercised is reached.

[0064] Furthermore, the inventors have considered allocating usage fees in proportion to the rights ratio to the rights holder's allocation address for the transaction amount at the time of settlement when a liquid business information type digital claim token, a user-restricted business information type digital claim token, or business information type digital information for personal attribute information trading is agreed upon.

[0065] The inventor then combined the measures derived from the above-mentioned considerations and studies, as appropriate, assuming various cases, and after further consideration and study, has derived a business information-type digital information guard and trading system that can preserve digital assets consisting of (basically) small amounts of data linked to personal information in real time, strongly and efficiently protects important information such as confidential information and personal information from high-level cyber attacks and physical destruction, restores important information without it being stolen by third parties even if it is subjected to cryptographic analysis using a quantum computer or an EMP attack, or makes it impossible for third parties to restore the management information even if it is stolen by a third party, and makes it possible to effectively utilize (basically) small amounts of data linked to personal information and generate profits.
