[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0022] At present, when data intellectual property platforms handle data intellectual property-related businesses, they often encounter the following problems: 1. At present, each data intellectual property platform often adopts a relatively isolated information management model, that is, each data intellectual property platform is managed separately and data is stored in a decentralized manner. As a result, information synchronization between different intellectual property platforms is impossible, resulting in a serious information island effect; 2. Due to the serious information island effect, the transparency of information disclosure is limited. In this case, there is also the risk of data tampering and unreasonable transactions when handling data intellectual property-related businesses. Furthermore, it will also make it more difficult to authenticate and trace rights, making it difficult to identify and hold accountable for infringement of data intellectual property rights; 3. Since different data intellectual property platforms cannot synchronize information, they are unable to work together in important links such as registration, review, ownership change, and transfer of data intellectual property, resulting in low business processing efficiency and increased labor and time costs.

[0023] Based on this, the embodiments of the present application provide a business processing method, device, electronic device and computer-readable storage medium to solve the above problems.

[0024] Figure 1 For a block diagram of the business processing system, see Figure 1 The business processing system includes an electronic device 10 and a blockchain network 20, and the electronic device 10 is communicatively connected to the blockchain network 20.

[0025] Optionally, an intellectual property platform may be provided on the electronic device, and the intellectual property platform is used to process data intellectual property related businesses and upload intellectual property data corresponding to the data intellectual property.

[0026] It can be understood that the blockchain network can communicate with multiple electronic devices to obtain the intellectual property data corresponding to each data intellectual property uploaded by each intellectual property platform and store these data.

[0027] Optionally, the intellectual property platform may be a national intellectual property platform, a provincial intellectual property platform or a municipal intellectual property platform.

[0028] In this embodiment, if the intellectual property platform is a provincial intellectual property platform, the intellectual property platform is also used to obtain the rules and regulations issued by the national intellectual property platform, and issue the rules and regulations to the corresponding municipal intellectual property platforms.

[0029] In addition, the provincial intellectual property platform is also used to obtain relevant data reported by various municipal intellectual property platforms, organize the relevant data to form a provincial intellectual property database, and report the relevant data of the province to the national intellectual property platform, so that the national intellectual property platform can organize the data reported by various provincial intellectual property platforms to form a national intellectual property database.

[0030] Optionally, different IP platforms can adopt standardized interface specifications and data exchange protocols, and ensure accurate, secure and reliable information exchange through unified data formats and security encryption measures. Optionally, the interface can adopt a RESTful architecture style to ensure simplicity and ease of understanding, and can support HTTP / HTTPS protocols for data transmission, including GET, POST, PUT, DELETE and other methods to meet different operation requirements.

[0031] Optionally, industry-wide accepted data formats such as JSON or XML can be used to encapsulate the data content transmitted by the interface to ensure that the data structure is clear and easy to parse, and can effectively reduce problems caused by incompatible data formats. At the same time, strict field definitions and encoding rules can be set for the intellectual property data of the data intellectual property.

[0032] Optionally, security control measures based on OAuth2.0 or other security authentication protocols can be introduced during the interface call process to ensure that only authorized users and services can access and modify data.

[0033] Optionally, two-way SSL / TLS encrypted communication can be performed during data interaction to encrypt the transmission of sensitive data (such as authentication information, data intellectual property details), preventing the data from being intercepted or tampered with during transmission.

[0034] Optionally, mature message serialization technologies, such as protobuf or Avro, can be used to convert business objects into byte streams to improve transmission efficiency and reduce bandwidth usage, while ensuring efficient transmission and accurate recovery of data in a network environment.

[0035] Optionally, a clear error code system and response message format can be defined. When an interface call is abnormal, detailed error information and suggested solutions can be returned, allowing the caller to quickly locate the problem and take appropriate action. In addition, a sound logging system can be designed to record all interactive behaviors during the interface call process to facilitate problem troubleshooting and optimize service performance.

[0036] Optionally, version management and backward compatibility strategies can be implemented for interface updates and iterations. When a new version of the interface is released, the old version of the interface can continue to be used for a certain period of time, providing sufficient time for each intellectual property platform to upgrade and adapt.

[0037] Optionally, in Figure 1 On the basis of Figure 2 For a block diagram of an electronic device 10 provided in an embodiment of the present application, please refer to Figure 2 The electronic device 10 includes a memory 100, a processor 110 and a communication module 120. The memory 100, the processor 110 and the communication module 120 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines.

[0038] The memory 100 is used to store computer programs or data that can be executed by the processor. The memory 100 can be, but is not limited to, a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable read-only memory (EEPROM), etc.

[0039] The processor 110 is used to read / write data or computer programs stored in the memory and execute corresponding functions.

[0040] The communication module 120 is used to establish a communication connection between the electronic device and other communication terminals through the network, and to send and receive data through the network. It should be understood that Figure 2 The structure shown is only a schematic diagram of the structure of the electronic device. The electronic device may also include Figure 2 More or fewer components as shown, or with Figure 2 Different configurations are shown. Figure 2 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0041] Next, the above Figure 1 The electronic device in the embodiment is the execution subject, and the business processing method provided in the embodiment of the present application is exemplarily introduced in combination with the flow chart.

[0042] Specifically, Figure 3 A flowchart of a business processing method provided in an embodiment of the present application is shown in Figure 3 , the method can be implemented through steps S20 to S22.

[0043] Step S20: obtaining a service processing request sent by the user.

[0044] Optionally, the service processing request may include service data.

[0045] Optionally, the business processing request may be initiated by an enterprise through the intellectual property platform, or may be initiated by some institutions, such as a court, a bank, etc., through the intellectual property platform.

[0046] Step S21, obtaining the intellectual property data corresponding to the target data intellectual property from the blockchain network according to the business data.

[0047] Optionally, the target data intellectual property refers to the data intellectual property targeted by the business processing request.

[0048] Step S22: If the intellectual property data corresponding to the target data intellectual property meets the preset business processing conditions, the target business is executed on the target data intellectual property according to the business processing request.

[0049] Optionally, the service processing conditions may be determined by developers in advance according to each service and stored in the electronic device.

[0050] It is understandable that the business processing conditions corresponding to different businesses may be different.

[0051] Optionally, considering that there may be a large number of users using the intellectual property platform at the same time, the intellectual property platform may buffer and schedule data through a message queue.

[0052] In an example, the message queue may be Kafka, RabbitMQ, etc., which is not limited in this application.

[0053] In this embodiment, when the intellectual property platform receives service requests, these requests are first converted into message format and stored in the message queue. The queue processes messages using the first-in-first-out principle to ensure that tasks can be executed in sequence and stably under high data load or poor network conditions, thereby optimizing data consistency management and improving the system's ability to respond to sudden requests, thereby enhancing overall system reliability.

[0054] In the business processing method provided by the embodiment of the present application, an intellectual property platform may be provided on an electronic device, and the electronic device may be connected to a blockchain network for communication. The blockchain network stores intellectual property data corresponding to each data intellectual property uploaded by each intellectual property platform. The electronic device may obtain a business processing request sent by a user, and obtain intellectual property data corresponding to the target data intellectual property from the blockchain network according to the business data in the business processing request, so that when the intellectual property data corresponding to the target data intellectual property meets the preset business processing conditions, the target data intellectual property is executed according to the business processing request. In this method, each intellectual property platform may upload the intellectual property data corresponding to each data intellectual property to the blockchain network, and obtain the intellectual property data corresponding to the target data intellectual property from the blockchain network when corresponding business processing is required, so as to realize information interaction and synchronization between each intellectual property platform through the blockchain network, and break the information island effect between data intellectual property platforms.

[0055] In addition, since each intellectual property platform can upload the intellectual property data corresponding to each data intellectual property to the blockchain network, the intellectual property data of each data intellectual property can be made public to each platform through the blockchain network, preventing users from arbitrarily tampering with the data intellectual property, ensuring the security of the intellectual property data, and improving the transparency of the data intellectual property. It is also conducive to the subsequent authentication and tracing of rights, and is convenient for the identification and accountability of infringements of data intellectual property.

[0056] Furthermore, through this method, different intellectual property platforms can synchronize information through the blockchain network, thereby achieving collaborative work between different intellectual property platforms, improving business processing efficiency, and reducing labor and time costs.

[0057] Optionally, there may be multiple businesses targeting data intellectual property rights, but in order to protect the data intellectual property rights and facilitate the smooth development of other businesses, the data intellectual property rights need to be registered first.

[0058] In this embodiment, the user can apply for data intellectual property registration through the intellectual property platform and upload the content and ownership information of the target data intellectual property to be registered.

[0059] It can be understood that, based on this, the above-mentioned business processing request may include a registration request, and the business data may include content data of the target data intellectual property rights and the first ownership information.

[0060] Optionally, the content data may be description information of the target data intellectual property rights.

[0061] Optionally, the first ownership information may be a document proving ownership of the target data intellectual property rights and other necessary supporting materials that can prove ownership.

[0062] In this embodiment, the electronic device can obtain the registration information of the target data intellectual property rights from the blockchain network based on the content data.

[0063] It is understandable that if the target data intellectual property has not been registered by other users before, the registration information should be empty.

[0064] It is understandable that the target data intellectual property can only be registered when it has not been registered by other users before. If the target data intellectual property has been registered by other users, there will be a registration conflict at this time, which can be resolved by a preset conflict resolution method.

[0065] In one example, the later registration application may be rejected according to the time sequence, or the registration conflict may be resolved through the intervention of a reviewer.

[0066] In this embodiment, the preset service processing condition may be that the registration information of the target data intellectual property is empty. If the preset service processing condition is met, the electronic device may perform a registration service on the target data intellectual property according to the registration request. Specifically, if the registration information of the target data intellectual property is empty, the electronic device may generate a first registration certificate for the target data intellectual property according to the content data of the target data intellectual property and the first ownership information.

[0067] Optionally, the registration certificate may include user information for registering the target data intellectual property, registration certificate ID, registration time, description information of the target data intellectual property, and the like.

[0068] In this embodiment, after generating the first registration certificate, the electronic device may send the first registration certificate to the user, and upload the first registration certificate, content data, and first ownership information to the blockchain network, so that the blockchain network can update the registration information of the target data intellectual property rights according to the first registration certificate, and store the first ownership information and content data of the target data intellectual property rights.

[0069] Optionally, the registration information may include a first registration certificate, a registrant, a registration platform, and the like.

[0070] In this embodiment, the electronic device can determine through the blockchain network whether other users have registered the target data intellectual property through this intellectual property platform or other intellectual property platforms, and thus register the target data intellectual property if the target data intellectual property has not been registered, thereby ensuring the security and accuracy of the data intellectual property registration process.

[0071] Optionally, after the data intellectual property is registered, users can also perform other business operations on the data intellectual property they hold, including trading the data intellectual property and pledging the data intellectual property for financing.

[0072] Next, we will give an illustrative introduction to the data intellectual property transaction business and pledge financing business respectively.

[0073] Optionally, for the transaction business of data intellectual property rights, if a transaction party wants to purchase the data intellectual property rights of a party to be traded, it may first initiate a transaction request for the target data intellectual property rights to the party to be traded.

[0074] Optionally, if the transaction party is willing to conduct a transaction with the transaction party, the registration certificate of the target data intellectual property rights may be sent to the transaction party so that the transaction party can confirm the relevant information of the target data intellectual property rights.

[0075] In this embodiment, in order to ensure the transaction reliability and legality of the target data intellectual property, the transaction parties can confirm the specific circumstances of the target data intellectual property. Therefore, the transaction parties can send a transaction request to the intellectual property platform on the electronic device based on the registration certificate to be sent by the transaction parties.

[0076] It can be understood that based on this, the above-mentioned business processing request can be a transaction request, the business data includes the second registration certificate, and the intellectual property data can include the first registration certificate of the target data intellectual property, the first ownership information and the first transaction status information.

[0077] Optionally, the second registration certificate refers to an unverified registration certificate uploaded by the transaction party.

[0078] In this embodiment, the electronic device can obtain the first registration certificate, first ownership information and first transaction status information of the target data intellectual property rights from the blockchain network based on the second registration certificate.

[0079] Optionally, the electronic device can query in the blockchain network according to the registration ID of the second registration certificate, thereby obtaining the first registration certificate, first ownership information and first transaction status information of the target data intellectual property rights.

[0080] Optionally, the first transaction status information may indicate whether the target data intellectual property is in a transaction status.

[0081] It can be understood that the first ownership information refers to the information on the current ownership of the target data intellectual property obtained from the blockchain network. This information may be consistent with the ownership information when the data intellectual property was registered, or it may be inconsistent with the ownership information when the data intellectual property was registered.

[0082] Optionally, the electronic device may also obtain content data, historical transaction information, etc. of the target data intellectual property.

[0083] It is understandable that if the target data intellectual property has not been registered and the user directly initiates a transaction request, or the registration fails or is invalid, the intellectual property data corresponding to the target data intellectual property should be empty.

[0084] Optionally, the business data may also include second ownership information.

[0085] It can be understood that the second ownership information is the information of the party to be traded.

[0086] In this embodiment, the electronic device can determine whether to execute the transaction service according to the second registration certificate, the second ownership information, the first registration certificate, the first ownership information and the first transaction status information.

[0087] Specifically, if the first registration certificate of the target data intellectual property matches the second registration certificate, the first ownership information matches the second ownership information, and the first transaction status information indicates that the target data intellectual property is not currently in a pending transaction state, the electronic device can send transaction confirmation information to the user, generate second transaction status information for the target data intellectual property, and upload the second transaction status information to the blockchain network.

[0088] Optionally, the second transaction status information represents that the target data intellectual property right is currently in a pending transaction state.

[0089] It is understandable that the above business processing conditions may include that the first registration certificate of the target data intellectual property rights matches the second registration certificate, the first ownership information matches the second ownership information, and the first transaction status information indicates that the target data intellectual property rights are not currently in a pending transaction state. It is understandable that if the transaction is reliable, the second registration certificate provided by the pending transaction party should not have been modified, so the second registration certificate should match the queried first registration certificate.

[0090] In addition, in order to avoid the situation where the party to the transaction sells the target data intellectual property rights multiple times, for example, first selling the target data intellectual property rights to enterprise A and then selling the target data intellectual property rights to enterprise B after the transaction is completed, thereby causing the transaction to be illegal, it is also necessary to compare whether the current actual owner of the target data intellectual property rights is the party to the transaction.

[0091] It can be understood that if the first ownership information matches the second ownership information, it can be determined that the above-mentioned multiple sales problem does not exist.

[0092] Furthermore, in order to avoid the situation where the parties to the transaction sell the target data intellectual property rights multiple times at the same time, for example, first agreeing to sell the target data intellectual property rights to enterprise A, and then agreeing to sell the target data intellectual property rights to enterprise B before the transaction is completed and the ownership information is changed, thereby causing a transaction conflict, the electronic device also needs to determine whether the target data intellectual property rights are currently in a pending transaction state based on the first transaction status information, that is, the state of being traded but not yet completed.

[0093] It can be understood that if the first transaction status information indicates that the target data intellectual property is not currently in a pending transaction state, it can be determined that there is no situation where the pending transaction party sells the target data intellectual property multiple times at the same time.

[0094] In this embodiment, if the target data intellectual property does not meet the business processing condition, the electronic device may determine that a transaction conflict occurs at this time, and may handle the transaction conflict according to a preset transaction conflict resolution method.

[0095] For example, you can reject transaction requests that come in later in order of transaction time, or request staff to intervene to handle transaction conflicts.

[0096] In this embodiment, if the electronic device determines that the transaction can be carried out, it can send transaction confirmation information to the user, and generate second transaction status information indicating that the target data intellectual property is in a pending transaction state, and upload the second transaction status information to the blockchain network for query by other intellectual property platforms.

[0097] Optionally, the transaction confirmation information may include information obtained from the blockchain network based on the second registration certificate, and conclusion information on whether the transaction review has passed or failed.

[0098] Optionally, the transaction party can further determine whether to conduct a transaction with the transaction party based on the information and conclusion information obtained by the electronic device from the blockchain network.

[0099] Optionally, if the transaction party conducts a transaction with the party to be traded, the transaction completion information can be uploaded through the intellectual property platform when the transaction is completed.

[0100] In this embodiment, the electronic device may receive transaction completion information for the target data intellectual property rights sent by the user.

[0101] Among them, the transaction completion information includes transaction parameters and ownership change information.

[0102] Optionally, the transaction parameters may include the transaction contract, transfer record, transaction date, information of both parties to the transaction, etc.; the ownership change information may include the ownership change consent information of both parties, transaction party information, etc.

[0103] In this embodiment, the electronic device can also send transaction parameters and ownership change information to the blockchain network so that the blockchain network can update the second transaction status information and first ownership information of the target data intellectual property rights according to the transaction parameters and ownership change information.

[0104] Optionally, the blockchain network can store the transaction parameters and generate a transaction record for the target data intellectual property.

[0105] Optionally, the blockchain network can update the owner information of the target data intellectual property rights to the transaction party by updating the first ownership information.

[0106] Optionally, since the transaction has ended at this time, the blockchain network can also update the second transaction status information so that the second transaction status information indicates that the target data intellectual property is in a transaction-ended state at this time.

[0107] Optionally, for the pledge financing business of data intellectual property rights, if the user wants to pledge the target data intellectual property rights to a bank for financing, he or she may initiate a pledge financing request for the target data intellectual property rights to the bank.

[0108] Optionally, the pledge financing request may include a registration certificate of the target data intellectual property rights, and the bank may confirm the relevant information of the target data intellectual property rights based on the registration certificate.

[0109] In this embodiment, in order to ensure the reliability and legality of the pledge financing of the target data intellectual property, the bank can confirm the specific circumstances of the target data intellectual property. Therefore, the bank can send a pledge financing request to the intellectual property platform on the electronic device based on the registration certificate sent by the user.

[0110] It can be understood that based on this, the above-mentioned business request can be a pledge financing request, the business data can include a third registration certificate, and the intellectual property data can include the first registration certificate of the target data intellectual property, the first ownership information, the pledge financing information and the first pledge financing status information.

[0111] Optionally, the third registration certificate refers to an unverified registration certificate uploaded by the bank.

[0112] In this embodiment, the electronic device can obtain the first registration certificate, first ownership information, pledge financing information and first pledge financing status information of the target data intellectual property rights from the blockchain network based on the third registration certificate.

[0113] Optionally, the electronic device can query in the blockchain network according to the registration ID of the third registration certificate, so as to obtain the first registration certificate, first ownership information, pledge financing information and first pledge financing status information of the target data intellectual property rights.

[0114] Optionally, the pledge financing information may indicate whether the target data intellectual property has been currently pledged for financing; the first pledge financing status information may indicate whether the target data intellectual property is in a state of awaiting pledge financing.

[0115] It is understandable that the first ownership information refers to the information of the current ownership of the target data intellectual property obtained from the blockchain network, which may be consistent with the ownership information when the data intellectual property is registered, or it may be inconsistent with the ownership information when the data intellectual property is registered. It is understandable that if the target data intellectual property has not been registered and the user directly initiates a pledge financing request, or the registration fails or the registration is invalid, the intellectual property data corresponding to the target data intellectual property should be empty.

[0116] Optionally, the electronic device may also obtain historical pledge financing information of the target data intellectual property, content data, financial information of users who pledge financing for the target data intellectual property, etc. Optionally, the business data also includes third-party ownership information.

[0117] It can be understood that the third ownership information is the information of the user who pledges the target data intellectual property for financing.

[0118] In this embodiment, the electronic device can determine whether to execute the pledge financing business based on the third registration certificate, the third ownership information, the first registration certificate, the first ownership information, the pledge financing information and the first pledge financing status information.

[0119] Specifically, if the first registration certificate of the target data intellectual property rights matches the third registration certificate, the first ownership information matches the third ownership information, the pledge financing information indicates that the target data intellectual property rights have not been pledged for financing, and the first pledge financing status information indicates that the target data intellectual property rights are not in a state of pending pledge financing, then the electronic device may send pledge financing confirmation information to the user, generate second pledge financing status information for the target data intellectual property rights, and upload the second pledge financing status information to the blockchain network.

[0120] Optionally, the second pledge financing status information indicates that the target data intellectual property is currently in a state of awaiting pledge financing.

[0121] It can be understood that the above-mentioned business processing conditions may include that the first registration certificate and the third registration certificate of the target data intellectual property rights match, the first ownership information and the third ownership information match, the pledge financing information indicates that the target data intellectual property rights have not been pledged for financing, and the first pledge financing status information indicates that the target data intellectual property rights are not in a state to be pledged for financing.

[0122] It can be understood that if the pledge financing is legal, the third registration certificate provided by the user should not have been modified, so the third registration certificate should match the queried first registration certificate.

[0123] In addition, in order to avoid the situation where users repeatedly pledge the target data intellectual property for financing, for example, first pledge the target data intellectual property for financing to Bank A, and then pledge the target data intellectual property for financing to Bank B after this pledge financing is completed, thereby resulting in illegal pledge financing, it is also necessary to compare whether the current actual owner of the target data intellectual property is the user who pledged the target data intellectual property for financing.

[0124] It can be understood that if the first ownership information matches the second ownership information, it can be determined that the above-mentioned problem of multiple repeated pledge financing does not exist.

[0125] Optionally, in order to ensure the legality of pledge financing, the bank also needs to ensure that the target data intellectual property is not currently in a state of being pledged for financing.

[0126] In this embodiment, the electronic device can determine whether the target data intellectual property is currently pledged for financing based on the pledge financing information.

[0127] Furthermore, in order to avoid the situation where the user pledges the target data intellectual property for financing multiple times at the same time, for example, first pledging the target data intellectual property for financing to Bank A, and then pledging the target data intellectual property for financing to Bank B before the pledge financing is completed, thereby causing a pledge financing conflict, the electronic device also needs to determine whether the target data intellectual property is currently in a pending pledge financing status based on the first pledge financing status information, that is, the pledge financing has been proposed but the pledge financing has not yet been completed.

[0128] It can be understood that if the first pledge financing status information indicates that the target data intellectual property is not currently in a state to be pledged for financing, it can be determined that there is no situation where the above-mentioned user pledges the target data intellectual property for financing multiple times at the same time.

[0129] In this embodiment, if the target data intellectual property does not meet the business processing conditions, the electronic device can determine that a pledge financing conflict has occurred at this time, and can handle the transaction conflict according to a preset pledge financing conflict resolution method.

[0130] For example, you can reject pledge financing requests that come later in chronological order, or apply for staff to intervene to handle pledge financing conflicts.

[0131] In this embodiment, if the electronic device determines that pledge financing can be carried out, it can send pledge financing confirmation information to the user, and generate second pledge financing status information representing that the target data intellectual property is in a state of pending pledge financing, and upload the second pledge financing status information to the blockchain network for other intellectual property platforms to query.

[0132] Optionally, the pledge financing confirmation information may include information obtained from the blockchain network based on the third registration certificate, as well as conclusion information on whether the pledge financing review has passed or failed.

[0133] Optionally, the bank can further determine whether to approve the pledge financing of the target data intellectual property based on the information and conclusion information obtained by the electronic device from the blockchain network.

[0134] Optionally, if the bank approves the pledge financing of the target data intellectual property, the pledge financing completion information can be uploaded through the intellectual property platform when the pledge financing is completed.

[0135] In this embodiment, the electronic device can receive pledge financing completion information for the target data intellectual property sent by the bank.

[0136] Optionally, the pledge financing completion information includes pledge financing parameters.

[0137] Optionally, the pledge financing parameters may include pledge terms, pledge time, financing amount, pledge financing consent information of both parties, etc.

[0138] Optionally, the electronic device may send the pledge financing parameters to the blockchain network so that the blockchain network updates the pledge financing information and the second pledge financing status information of the target data intellectual property rights according to the pledge financing parameters.

[0139] Optionally, the blockchain network can update the pledge financing information according to the pledge financing parameters so that the pledge financing information represents that the target data intellectual property is in a state of being pledged for financing.

[0140] Optionally, since the pledge financing has ended at this time, the blockchain network can also update the second pledge financing status information so that the second pledge financing status information represents that the target data intellectual property is in a pledge financing process completion state at this time.

[0141] In this embodiment, when the electronic device conducts transactions or pledges financing for the target data intellectual property, it is necessary to match and confirm the data uploaded by the user and the data obtained from the blockchain network, so as to prevent the data from being tampered with by the user. In addition, the electronic device can also determine the specific transaction status or pledge financing status of the target data intellectual property through the first transaction status information, the first pledge financing status information and the pledge financing information, thereby avoiding non-compliant transaction operations and pledge financing operations, and improving the legality and reliability of transactions and pledge financing. Optionally, users can also conduct data query services through the data intellectual property platform. For example, users can conduct data queries when they need to understand the overall data intellectual property situation of the industry. In addition, when users need legal aid or dispute mediation, the court or law firm can collect evidence of the target data intellectual property to be mediated through the data intellectual property platform.

[0142] Optionally, based on this, the above-mentioned business processing request may be a data acquisition request, and the business data may include the fourth registration certificate.

[0143] Optionally, the fourth registration certificate refers to an unverified registration certificate uploaded by the user.

[0144] In this embodiment, the electronic device can obtain the registration information of the target data intellectual property rights from the blockchain network based on the fourth registration certificate.

[0145] Optionally, if the target data intellectual property has been registered before, the registration information should not be empty.

[0146] It can be understood that if the registration information is empty, it means that the target data intellectual property has not been registered, and then no other data corresponding to the target data intellectual property will be stored in the blockchain network, so the electronic device can return a query failure message.

[0147] Specifically, if the registration information of the target data intellectual property is not empty, the electronic device can obtain the target intellectual property data of the target data intellectual property from the blockchain according to the data acquisition request, and send the target intellectual property data to the user.

[0148] It can be understood that if the registration information of the target data intellectual property is not empty, it means that the information required by the user can be obtained for the target data intellectual property, such as for rights protection and evidence collection, and the electronic device can obtain the target intellectual property data of the target data intellectual property according to the data acquisition request.

[0149] Optionally, the target intellectual property data may include one or more of ownership information, content data, transaction information, and pledge financing information.

[0150] It is understandable that if the data acquisition request is a request for rights protection and evidence collection, the electronic device needs to obtain all relevant information about the intellectual property rights of the target data.

[0151] Optionally, when applying to courts or other institutions for rights protection and evidence collection, users can upload the registration certificate of the target data intellectual property rights to be protected, as well as the infringement situation, expected legal aid, etc., and the court can then conduct comprehensive evidence collection based on the registration certificate of the target data intellectual property rights.
