[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] In order to avoid the problem of data leakage that is prone to occur in the shared data storage process in the prior art, the embodiment of the present application deploys shared data by adopting a blockchain-based approach, and the shared data is processed data, while the original data will be stored locally on the sharing party and can only be obtained through application or authorization, which can well ensure the security of the shared data; specifically, Figure 1 A data processing method based on blockchain is provided in an embodiment of the present application. The method is applied to a blockchain node in a shared alliance chain. The method may include the following steps:

[0048] Step S110: publishing the data to be shared.

[0049] The data to be shared includes target shared data, which is obtained by performing preset processing on the original shared data. The target shared data has a definite corresponding relationship with the original shared data.

[0050] The embodiment of the present application establishes a shared alliance chain, which includes blockchain nodes deployed by each party to be shared, and each blockchain node is communicatively connected.

[0051] In the embodiment provided in the present application, each participant will deploy a blockchain node respectively, and these blockchain nodes will form a shared blockchain alliance, and the blockchain nodes in the shared blockchain alliance are connected to each other. Among them, each participant can be a party to be shared with data, or can include not only the party to be shared with data but also the party to obtain the shared data.

[0052] Each party to be shared in the embodiment of the present application will publish the data to be shared on the blockchain node deployed by itself, so that other participants in the shared alliance chain can access the published data to be shared through the shared alliance chain.

[0053] It should be noted that the data to be shared that is published by the party to be shared to the corresponding node of the shared alliance chain in the embodiment of the present application is data processed by a preset processing method, rather than the original data; for example, the published data to be shared is a hash value obtained after hash processing, and its original data will be stored in the service node inside the provider of the data to be shared, so that it can be avoided that the original data will not be affected by the leakage of the data to be shared. Of course, in addition to processing the original data by hashing to obtain the target shared data in the embodiment of the present application, other methods can be used for processing as needed to ensure that the target shared data has a certain corresponding relationship with the original shared data, so that it is very convenient to find the original data stored in the service node of the party to be shared through the data to be shared.

[0054] In addition, in order to prevent the above-mentioned preset processing method from being leaked and affecting the original data corresponding to the shared data deployed in the shared alliance chain, only part of the original data, such as the name or other less important data, can be processed by preset processing to obtain the target shared data, without having to process all the original data through, for example, hashing to obtain the target data. This can further and better avoid the risk of leakage of the original data.

[0055] It should be noted that, in addition to the target shared data, the data to be shared may also include data description information, which is used to describe the functions of the target shared data on the blockchain node in the shared alliance chain. In this way, other participants can directly understand what data the target shared data contains or what functions it has through the data description information, so that other participants can better understand whether they need to obtain the target shared data. In addition, the data to be shared may also include a data score, which is the score given by the requesting party after obtaining the data of the blockchain node in the shared alliance chain. In this way, other participants can understand the excellence of the target shared data through the score. Of course, when the provider of the data to be shared shares the data for the first time, there is no user score. After other users use the shared data, if they score it, the data to be shared will store the score and share it with other users.

[0056] Step S120: receiving a use request for the shared data.

[0057] Step S130: sending original shared data corresponding to the data to be shared.

[0058] When a request from a requesting party to use the data to be shared stored in the shared alliance chain is received, the corresponding original shared data is sent to the requesting party through the provider of the data to be shared.

[0059] In an embodiment of the present application, if the requesting party is interested in the data to be shared stored in the shared alliance chain and wants to obtain the corresponding original data, the request method can send a request to the data provider through the blockchain node in the shared alliance chain. In this way, when the provider of the data to be shared receives the requesting party's request to use the data to be shared stored in the shared alliance chain, the provider will review the request. If the review is passed, the corresponding original data will be sent to the requesting party.

[0060] The data processing method based on blockchain provided in the embodiment of the present application establishes a shared alliance chain, publishes the data to be shared provided by the sharing party to the blockchain node corresponding to the shared alliance chain, and upon receiving the request from the requesting party to use the data to be shared stored in the shared alliance chain, sends the corresponding original shared data to the requesting party through the provider of the data to be shared. This can avoid the risk of data leakage caused by the prior art of directly storing and sharing the original data, and can also record the data sharing records of the participants on each blockchain node in real time through blockchain technology, which can avoid data tampering and facilitate subsequent accountability.

[0061] Among them, based on the above-mentioned embodiments of the present application, in other embodiments provided in the present application, the contributed data can also be processed in a pass point system. For example, when it is detected that the requesting party obtains the original shared data sent by the provider of the data to be shared, the requesting party will reduce the preset amount of pass points, and the provider will increase the preset amount of pass points. Among them, the pass points can be exchanged through relevant rights and interests, which can be formulated according to specific circumstances.

[0062] In addition, in the embodiment provided by the present application, the contracts of each party to be shared can be deployed to the target blockchain node by selecting the target blockchain node on the shared alliance chain. The addresses of each party to be shared on the blockchain are obtained and the addresses are synchronously recorded on the contract. The contract includes the sharing rules that each party to be shared complies with.

[0063] In order to better realize data sharing and acquisition of shared data by each participant on the shared alliance chain, in another embodiment provided in this application, based on the above embodiment provided in this application, Figure 2 As shown, the above method, step S130 may further include the following steps:

[0064] Step S131, determining whether the user requesting the data to be shared has the audit-free authorization for the data to be shared stored in the shared alliance chain;

[0065] If so, in step S132, the original shared data corresponding to the data to be shared is sent to the user requesting party;

[0066] If not, in step S133, an audit request sent by the user requesting party is received. If the audit is passed, the user requesting party is added to the data authorization list. The authorization list is published on the blockchain node in the shared alliance chain. The user requesting party included in the data authorization list has the authorization-free permission; and the original shared data corresponding to the data to be shared is sent to the user requesting party.

[0067] The embodiment provided by the present application can be authorized by review. If the user requesting party enjoys the review-free authorization, the provider of the data to be shared can directly send the corresponding original shared data to the user requesting party, avoiding the tediousness of re-reviewing it. If the user requesting party does not enjoy the review-free authorization, the user requesting party can send a review request to the provider of the data to be shared. The provider of the data to be shared will review it after receiving the review request through the blockchain node. If the review is passed, the user requesting party will be added to the data authorization list, so that the user requesting party can enjoy the convenience provided by the review-free authorization the next time it requests to obtain the data to be shared. Among them, the authorization list is published on the corresponding blockchain node in the shared alliance chain, and the user requesting party included in the data authorization list has the authorization-free authority.

[0068] Based on the above embodiment, in order to further explain how to send the corresponding original shared data to the user requesting party through the provider of the data to be shared, in another embodiment provided in the present application, the target shared data can specifically be blacklist data, such as Figure 3 As shown, step S130 may include the following steps:

[0069] Step S134, obtaining the first blacklist data published by the requesting party on the blockchain node in the shared alliance chain and the second blacklist data published by the provider of the data to be shared on the blockchain node in the shared alliance chain.

[0070] Step S135: taking the intersection of the first blacklist data and the second blacklist data as target blacklist data.

[0071] Step S136, obtaining the original shared data corresponding to the target blacklist data, and sending the original shared data to the use requesting party.

[0072] In the embodiment of the present application, the target shared data can be specifically blacklist data. For example, in many financial institutions, in order to reduce losses and avoid certain loans or investments from getting due returns, the relevant institutions or individuals who have lost their credit will be blacklisted. In the embodiment of the present application, if the amount of shared blacklist data is very large, and the blacklist data between financial institutions is inevitably repeated, in order to improve the efficiency of data sharing, and also to avoid the use of the requester after obtaining the blacklist data, the first blacklist data published by the requester on the blockchain node in the shared alliance chain and the second blacklist data published by the provider on the blockchain node in the shared alliance chain will be obtained in the embodiment of the present application. Do intersection processing, that is, the data that exists in the second blacklist data but does not exist in the first blacklist data is sent to the requester, which can well guarantee the transmission efficiency during data sharing, and can also better avoid the use of the requester after obtaining the blacklist data. Deduplication processing. In addition, cryptographic means such as homomorphic encryption can also be used to achieve secure multi-party computing without data being stored, to obtain the intersection of the blacklist data of both parties.

[0073] In addition, in the embodiment of the present application, after the service node of the requester synchronizes the data information from the blockchain node, a network connection is established with the service node of the data provider. The requester service node is used to encrypt the query list of the requester and transmit it directly to the blacklist data provider without going through the blockchain. After the provider receives the query list, it uses the Bloom filter to match the query list and then returns the calculation result. The whole process is completed off-chain, which effectively improves the transaction efficiency.

[0074] In another embodiment provided in the present application, a data processing method based on blockchain is also provided, which is applied to blockchain nodes in a shared alliance chain, such as Figure 4 As shown, the method may include the following steps:

[0075] Step S410: sending a request for using the data to be shared.

[0076] The data to be shared includes target shared data.

[0077] The target shared data is obtained by performing preset processing on the original shared data, and the target shared data has a definite corresponding relationship with the original shared data.

[0078] Step S510: receiving original shared data corresponding to the data to be shared.

[0079] The embodiment provided by the present application is the initiator of the use request of the blockchain node in the shared alliance chain corresponding to the above method, that is, after the user joins the shared alliance chain, if he needs to use the data to be shared in the shared alliance chain, he can send the use request of the data to be shared through the blockchain node in the shared alliance chain. In this way, when another blockchain node in the shared alliance chain receives the use request, it can send the original data corresponding to the data to be shared through the blockchain node in the shared alliance chain.

[0080] Among them, in the embodiment of the present application, the data to be shared that the party to be shared publishes to the corresponding node of the shared alliance chain is data processed by a preset processing method, rather than the original data; for example, the published data to be shared is a hash value obtained after hash processing, and its original data will be stored in the service node inside the provider, so that it can be avoided that the original data will not be affected after the data to be shared is leaked. Of course, in the embodiment of the present application, in addition to processing the original data by hashing to obtain the target shared data, other methods can be used for processing as needed to ensure that the target shared data has a certain corresponding relationship with the original shared data, so that the original data stored in the node of the party to be shared can be easily found through the data to be shared. For details, please refer to the above description, which will not be repeated here.

[0081] In addition, the blockchain nodes in the shared alliance chain can also send an audit request, so that after the audit request is passed, the user requesting the data to be shared will be added to the data authorization list. The authorization list is published on the blockchain node in the shared alliance chain, and the user requesting party included in the data authorization list has the authorization-free permission. In this way, the next time you need to use the data to be shared, you can use it directly without sending an audit request again; of course, as described above, you can also obtain the data to be shared through the points mechanism, etc., which will not be repeated here.

[0082] Illustratively, the above method provided in the embodiments provided in this application also provides applications in the following scenarios:

[0083] 1) Financial institution A checks the data shared by the shared alliance chain through the blockchain node, selects a piece of data with a high score, and finds out that the provider of the data is financial institution B by querying the data information; 2) Financial institution A queries whether it is included in the list of authorized institutions for the data. If it is not in the list of authorized institutions, it initiates an approval request to financial institution B; 3) After financial institution B approves the approval request, financial institution A directly sends the query list to financial institution B through the blockchain node; 4) After receiving the query list, financial institution B finds the relevant data content locally according to the hash of the data published on the chain, then performs blacklist matching, and finally returns the result to financial institution A; 5) A transaction is added to the blockchain, and the token points method of financial institutions A and B is updated.

[0084] This application introduces a scoring mechanism, where data users evaluate data based on how well the data matches their business. Data with high scores are more likely to be used, thereby obtaining token points and obtaining incentives outside the system from regulators. The scoring mechanism can effectively motivate data providers to control data quality. In terms of data security, only the hash of the data and other information are published on the chain, and the data content only exists on the service nodes within the organization, so that data can be calculated without leaving the warehouse and data leakage can be avoided. In terms of transaction efficiency, the introduction of an authorization mechanism can reduce the process in data exchange, and at the same time, the service nodes are used to directly share data, eliminating the blockchain consensus process and improving transaction efficiency.

[0085] In addition, in the embodiment of the present application, by introducing a token points strategy, the data publishing and data acquisition behaviors of the participants are associated with token points, and the token points are exchanged by financial regulatory agencies outside the system, which can greatly increase the willingness of the participants to share data. In the application of blockchain, by adopting a "decentralized" strategy, all participants have equal status. The embodiment of the present application can also audit all data usage by introducing regulatory agency participants to ensure the compliance and legal use of data and maintain the overall quality of shared data.

[0086] The data processing method based on blockchain provided in the embodiment of the present application establishes a shared alliance chain, publishes the data to be shared provided by the sharing party to the blockchain node corresponding to the shared alliance chain, and upon receiving the use request of the user requesting party for the data to be shared stored in the shared alliance chain, sends the corresponding original shared data to the user requesting party through the provider of the data to be shared. This can avoid the risk of data leakage caused by the prior art of directly storing and sharing the original data, and can also record the data sharing records of the participants on each blockchain node in real time through blockchain technology, which is convenient for subsequent accountability while avoiding data tampering. And through the relevant authorization mechanism, it is convenient for the user requesting party to obtain the shared data in a timely and convenient manner, and by sending the blacklist intersection data, the sharing efficiency of the shared data can be guaranteed.

[0087] In addition, the present application provides a data processing system based on blockchain, such as Figure 5 As shown, the system includes the system including a first blockchain node 10 and a second blockchain node 20 in a shared alliance chain:

[0088] A first blockchain node 10 is used to publish data to be shared, wherein the data to be shared includes target shared data, wherein the target shared data is obtained by performing preset processing on the original shared data, and the target shared data has a certain corresponding relationship with the original shared data;

[0089] The second blockchain node 20 is used to send a use request of the to-be-shared data to the first blockchain node;

[0090] The first blockchain node 10 is further used to receive a request to use the data to be shared, and send original shared data corresponding to the data to be shared.

[0091] Optionally, the second blockchain node is further used to send a review request;

[0092] The first blockchain node is also used for:

[0093] Determine whether the user requesting the data to be shared has the audit-free authorization for the data to be shared stored in the shared alliance chain;

[0094] If available, sending the original shared data corresponding to the data to be shared to the user requesting party;

[0095] If not, receive the review request sent by the user requesting party, and if the review is passed, add the user requesting party to the data authorization list, the authorization list is published on the blockchain node in the shared alliance chain, and the user requesting party included in the data authorization list has the authorization-free permission; and send the original shared data corresponding to the data to be shared to the user requesting party.

[0096] Optionally, the first blockchain node is also used to perform hash operation on the original shared data and use the processed data as the target shared data.

[0097] Optionally, the target shared data is blacklist data, and the first blockchain node is further used to:

[0099] Using the intersection of the first blacklist data and the second blacklist data as target blacklist data;

[0100] The original shared data corresponding to the target blacklist data is obtained, and the original shared data is sent to the use requesting party.

[0101] Optionally, the data to be shared also includes a data score, which is a score given by the user requesting party after obtaining the data of the blockchain node in the shared alliance chain.
