A method, device and medium for providing information with delay based on blockchain

Abstract

This application discloses a method, device, and medium for delayed information provision based on blockchain. The method includes: determining a pre-created blockchain platform; determining that the information to be written meets a first preset condition; writing the hash value of the information to be written into the blockchain platform; and writing the information to be written into the blockchain platform after determining that the information to be written meets a second preset condition. Since the data in the blockchain platform is public and transparent, nodes in the blockchain can query the information to be written at any time through appropriate channels. Furthermore, because the blockchain platform is a distributed storage system, data tampering by a single node will not take effect, thus ensuring the authenticity and trustworthiness of the data on the blockchain platform. When a user needs to store data, they can only write the hash value into the blockchain for storage, which not only saves time but also ensures that the information is not publicly exposed, protecting the user's privacy.

Description

Technical Field

[0001] This application relates to the field of blockchain, specifically to a method, device, and medium for providing information with delays based on blockchain. Background Technology

[0002] With the advancement of technology, more and more individuals and companies will generate more and more data and information of various types. Some of this information often needs to be stored in external space due to various reasons, such as insufficient local storage space or external storage.

[0003] However, this presents some problems. For example, storing large amounts of information in external storage can take a long time. Or, even if information is encrypted and stored in external storage, there is still a risk of it being decrypted and exposed. Summary of the Invention

[0004] To address the aforementioned issues, this application proposes a blockchain-based method for providing information with delayed delivery, comprising: determining a blockchain platform pre-created based on a blockchain framework, wherein the nodes in the blockchain platform include several users; determining that the information to be written meets a first preset condition, wherein the first preset condition is related to at least one of information quantity, information purpose, information content, and confidentiality level; writing the hash value of the information to be written into the blockchain platform; and, after determining that the information to be written meets a second preset condition, writing the information to be written into the blockchain platform, wherein the second preset condition is related to at least one of the information purpose, the confidentiality level, and the duration since the hash value was written into the blockchain platform.

[0005] In one example, the nodes in the blockchain platform also include a corresponding institution, which is related to the second preset condition; determining that the information to be written meets the second preset condition includes: receiving condition compliance information sent by the institution, indicating that the information to be written has met the second preset condition, and writing the condition compliance information into the blockchain platform.

[0006] In one example, the institution includes a patent office; determining that the information to be written meets a first preset condition includes: determining that the information to be written includes technical disclosure information, wherein the technical disclosure information is used to apply for a patent right; receiving condition compliance information sent by the institution, indicating that the information to be written has met a second preset condition, and writing the condition compliance information into the blockchain platform includes: receiving application information sent by the patent office, indicating that the information to be written has been applied for a patent, and writing the application information into the blockchain platform.

[0007] In one example, the institution includes a registration institution; determining that the information to be written meets a first preset condition includes: determining that the information to be written includes the user's identity information; receiving condition compliance information sent by the institution indicating that the information to be written meets a second preset condition, and writing the condition compliance information into the blockchain platform includes: receiving registration information sent by the registration institution indicating that the identity information is required for registration, and writing the registration information into the blockchain platform; writing the information to be written into the blockchain platform includes: encrypting the information to be written using the registration institution's public key and then writing it into the blockchain platform.

[0008] In one example, the institution includes a rating agency; determining that the information to be written meets a first preset condition includes: determining, through the rating agency, that the confidentiality level of the information to be written exceeds a preset level; receiving condition compliance information sent by the institution indicating that the information to be written has met a second preset condition, and writing the condition compliance information into the blockchain platform includes: receiving decrement information sent by the rating agency indicating that the confidentiality level of the information to be written has decreased to below the preset level, and writing the decrement information into the blockchain platform.

[0009] In one example, the method further includes: generating a smart contract and deploying it in the blockchain platform, wherein the smart contract includes the first preset condition, a hash algorithm, and the second preset condition.

[0010] In one example, the smart contract is used to: hash the information to be written using the hash algorithm to obtain the hash value when the information to be written meets the first preset condition; and write the hash value into the blockchain platform; and write the information to be written into the blockchain platform when the information to be written meets the second preset condition.

[0011] In one example, the method further includes generating a unique identifier for the digital object to be written, so that the user can query the information to be written.

[0012] On the other hand, this application also proposes a blockchain-based information delay provisioning device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to: determine a blockchain platform pre-created based on a blockchain framework, wherein nodes in the blockchain platform include a plurality of users; determine that information to be written meets a first preset condition, wherein the first preset condition is related to at least one of information amount, information purpose, information content, and confidentiality level; write the hash value of the information to be written into the blockchain platform; and after determining that the information to be written meets a second preset condition, write the information to be written into the blockchain platform, wherein the second preset condition is related to at least one of the information purpose, the confidentiality level, and the duration for which the hash value has been written into the blockchain platform.

[0013] On the other hand, this application also proposes a non-volatile computer storage medium for providing information delay based on blockchain, storing computer-executable instructions, wherein the computer-executable instructions are configured to: determine a blockchain platform pre-created based on a blockchain framework, wherein the nodes in the blockchain platform include several users; determine that the information to be written meets a first preset condition, wherein the first preset condition is related to at least one of information amount, information purpose, information content, and confidentiality level; write the hash value of the information to be written into the blockchain platform; and after determining that the information to be written meets a second preset condition, write the information to be written into the blockchain platform, wherein the second preset condition is related to at least one of the information purpose, the confidentiality level, and the duration for which the hash value has been written into the blockchain platform.

[0014] The method for delayed information provision proposed in this application can bring the following beneficial effects:

[0015] Because data on a blockchain platform is public and transparent, nodes can query the information to be written at any time through appropriate means. Furthermore, since the blockchain platform uses distributed storage, data tampering by a single node will not take effect, thus ensuring the authenticity and reliability of the data on the blockchain platform. When users need to store data, they can write only the hash value to the blockchain for storage, which not only saves time but also ensures that the information is not publicly exposed, protecting user privacy. Once a user wants to establish ownership, they only need to write the information to be written to the blockchain platform, and ownership can be established by hashing it.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown in the figure, this application provides a blockchain-based information delay provisioning method, including:

[0022] S101. Determine a blockchain platform pre-created based on a blockchain framework, wherein the nodes in the blockchain platform include several users.

[0023] Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanisms, and encryption algorithms. In essence, it is a decentralized database.

[0024] First, we can identify the blockchain platform built upon the blockchain framework. The blockchain framework can be any framework capable of implementing the functions described in the embodiments of this application, such as Bitcoin, Ethereum, Fabric, Corda, etc. The blockchain platform can refer to a platform that stores the blockchain, for example, a distributed system. Of course, the blockchain platform can also directly represent the blockchain itself, and this is not limited here.

[0025] In a blockchain platform, users can be deployed as nodes. Users can refer to individuals, companies, enterprises, groups, or various institutions and organizations; there are no specific limitations.

[0026] S102. Determine that the information to be written meets the first preset condition, wherein the first preset condition is related to at least one of the following: information amount, information purpose, information content, and confidentiality level.

[0027] S103. Write the hash value of the information to be written into the blockchain platform.

[0028] When a user wants to write information into the blockchain platform, they can first determine whether the information to be written, i.e. the information to be written, meets the first preset condition.

[0029] Specifically, when the first preset condition is related to the amount of information, such as when the amount of information to be written exceeds a preset threshold, it indicates that the amount of information to be written is large. If written directly, it would result in excessively long writing time, wasting the user's time and resources. In this case, the information to be written can be hashed, and then the hash value can be written into the blockchain platform.

[0030] When the first preset condition indicates that the user does not want to disclose the information to be written at this time, the first preset condition can be related to at least one of the following: information purpose, information content, and confidentiality level. The information purpose refers to the intended use of the information to be written, such as for applying for a patent, executing a project, or writing a paper. In this case, the first preset condition can be several preset information purposes. If the information to be written includes at least one of these preset information purposes, it can be determined that it meets the first preset condition. The information content refers to all or part of the content contained in the information to be written. The confidentiality level is determined in advance through a rating. The rating can be given to the user node itself, determining its level of confidentiality. The rating can also be given by a relevant institution or agency, and the evaluation can be based on various standards or regulations, without limitation here.

[0031] S104. When it is determined that the information to be written meets the second preset condition, the information to be written is written into the blockchain platform, wherein the second preset condition is related to at least one of the information purpose, the confidentiality level, and the duration for which the hash value has been written into the blockchain platform.

[0032] After the hash value of the information to be written is written into the blockchain platform, after a certain delay, if the information to be written meets the second preset condition, then the information to be written can be written into the blockchain platform for corresponding operations such as confirmation of rights and public disclosure.

[0033] Specifically, when the second preset condition is related to duration, for example, after the hash value has been written to the blockchain platform for a certain period of time, the information to be written can be written to the blockchain platform. This certain duration can be constant or determined separately for each piece of information to be written; no limitation is made here.

[0034] When the second preset condition indicates that the user can now publicly disclose the information to be written, the second preset condition can be related to at least one of the information's purpose and its confidentiality level. For example, when the purpose corresponding to the information to be written has been used up, the user no longer needs to hide it and can publicly disclose the information, at which point it can be written to the blockchain platform. The confidentiality level of the information to be written can also remain constant, but may decrease over time or as the project progresses. If the confidentiality level decreases below a certain threshold, then the information to be written can be written to the blockchain platform.

[0035] In one embodiment, the nodes in the blockchain platform may further include a corresponding institution, which is associated with the second preset condition; that is, whether the information to be written meets the second preset condition is determined by this institution. This institution can send a condition compliance message indicating that the information to be written meets the second preset condition, and then write this condition compliance message into the blockchain platform, at which point it can be concluded that the information to be written meets the second preset condition.

[0036] Specifically, the institution can include patent offices, such as the State Intellectual Property Office or relevant patent search agencies. The first presupposition condition is related to the purpose of the information. Determining that the information to be written meets the first presupposition condition can be that the information to be written includes technical disclosure information. Technical disclosure information can refer to a technical disclosure document used for patent application. If the technical disclosure document is not filed for patent, it will have a significant impact on the patent application process, causing the applied technology to become prior art. Therefore, in this case, only the hash value can be written to the blockchain platform. Then, when the institution sends the condition-compliant information, it can indicate that the information to be written has been applied for as patent information, meaning that the technical disclosure information can be made public, and at this time, the information to be written can be written to the blockchain platform.

[0037] Institutions can also include registration institutions. When users want to conduct business on certain platforms, businesses, or websites, they usually need to register. These institutions can then be referred to as registration institutions. The first preset condition is related to the information content. Determining that the information to be written meets the first preset condition can mean that the information to be written includes the user's identity information. Normally, a user's identity information is not convenient to disclose directly, as this would expose the user's privacy. Therefore, it can be hashed and written into the blockchain platform. Then, when an institution sends information indicating that the condition is met, it can be registration information indicating that the identity information is required for registration. At this time, the information to be written containing the identity information needs to be written into the blockchain platform. Direct writing would also expose the user's privacy; therefore, it can be encrypted using the registration institution's public key before writing.

[0038] The institution can also be a rating agency, which is used to rate the information to be written. This rating agency can be a third-party rating agency, such as a defense agency or a third-party certification body. For certain materials, such as information related to defense or industry secrets, users need to send the information to be written to the rating agency in advance for rating. The rating agency can also be an internal rating agency of the user's company; there are no restrictions here. The first preset condition is related to the level of confidentiality. When it is determined that the information to be written meets the first preset condition, the rating agency rates it and writes the level of confidentiality into the blockchain platform, confirming that the level of confidentiality exceeds a preset level. Then, in subsequent processes, when the level of confidentiality of the information to be written drops below the preset level, the rating agency can send the corresponding decrease information and write it into the blockchain platform, at which point the information to be written can be written into the blockchain platform.

[0039] In one embodiment, a corresponding smart contract can be pre-generated and deployed on the blockchain platform. The smart contract includes a first preset condition, a hash algorithm, and a second preset condition. The smart contract is used to hash the information to be written using the hash algorithm when the information to be written meets the first preset condition, obtain a hash value, and write the hash value into the blockchain platform. It is also used to write the information to be written into the blockchain platform when the information to be written meets the second preset condition. Since the smart contract on the blockchain platform is public, each node can verify whether the smart contract conforms to the pre-agreed terms and deploy it on its own node. Users can also query the smart contract through appropriate means, which improves the automation of transactions and further increases user trust. Furthermore, the smart contract can only be changed through upgrades, requiring synchronous deployment across all nodes. Once deployed, it can only be executed by the program, without human interference, thus enhancing data credibility.

[0040] In one embodiment, a Digital Object Unique Identifier (DOI) for the information to be written can also be generated, such as a QR code or barcode, to facilitate users in querying the information. For example, by scanning the QR code corresponding to the information to be written, users can access the data associated with that information, such as the hash value or a first preset condition, which is very convenient.

[0042] At least one processor; and,
