Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
The method and the device aim to solve the technical problems that when a data provider and a data demander trade data in a knowledge graph through a block chain, the data provider needs to store all data in the knowledge graph into the block chain, a large amount of storage space is occupied, and data trading efficiency is low in the related technology. The embodiment of the application provides a data processing method and device, electronic equipment and a storage medium.
For clarity of description of the solution, in the first aspect, a detailed description is first given of a data processing system provided in the embodiments of the present application.
Specifically, in the process of carrying out transaction on data in the knowledge graph through the blockchain, a data providing end, a data requiring end, namely a data receiving end, and a data transaction platform, namely a blockchain management server are involved. In practical application, the data providing end and the data receiving end can complete data transaction in the knowledge graph through the blockchain management server.
As can be seen from the above description, the data processing system provided in the embodiment of the present application may include a data providing end 11, a data receiving end 12, and a blockchain management server 13, as shown in fig. 1, and the interaction process of the data providing end 11, the data receiving end 12, and the blockchain management server 13 is as follows.
S110, the data providing terminal 11 sends a first data transaction request to the blockchain management server 13.
The first data transaction request carries node identification of a node corresponding to the data to be transacted in the knowledge graph and data description information of the data to be transacted.
Specifically, the data providing end is provided with a knowledge graph, wherein the knowledge graph is a large-scale data asset and has the characteristics of multi-domain relation associativity, frequent data updating and large data magnitude.
A knowledge spectrogram is a multi-relationship graph composed of nodes and edges of different types, where each node represents an entity and each edge represents a relationship between two nodes (which may be referred to as a head node and a tail node) connected by the edge, i.e., indicates that the head entity and the tail entity are connected together by a specific relationship. Each node has data.
When a data providing end wants to perform data transaction on some data in the knowledge graph, a first data transaction request may be sent to the blockchain management server, where the first data transaction request may carry a node identifier of a node corresponding to data to be transacted in the knowledge graph. For example, the data to be traded is data corresponding to the first node, data corresponding to the second node, and data corresponding to the third node, and then the data trading request may carry the node identifier G1 of the first node, the node identifier G2 of the second node, and the node identifier G3 of the third node. That is, the first node, the second node, and the third node are trusted nodes. Nodes except the first node, the second node and the third node in the knowledge graph are nodes which are not trusted, and data corresponding to the nodes which are not trusted cannot be subjected to data transaction, namely, the control of a trusted area is ensured.
In addition, in order to enable the data receiving end to know the data to be transacted in the subsequent steps, the data transaction request can also carry data description information of the data to be transacted.
S120, the blockchain management server 13 configures a key for the node identifier of the node corresponding to the data to be traded.
The key configured for the node identifier of the node corresponding to the data to be traded is the key corresponding to the block in the block chain.
Specifically, in the method adopted by the embodiment of the present application, instead of storing all data in the knowledge graph in the blockchain, each node in the knowledge graph is taken as an independent object, and each node points to one trusted block in the blockchain, wherein each trusted block corresponds to one key, and the keys corresponding to different trusted blocks are different. Therefore, data in the knowledge graph with large data magnitude can be traded efficiently, and the block chain does not need to be subjected to multiple times of full chain confirmation due to frequent changes of the data in the knowledge graph.
Therefore, after receiving the data transaction request, the blockchain management server can analyze the data transaction request to obtain the node identifier of the node corresponding to the data to be transacted carried in the data transaction request and the data description information of the data to be transacted. And after the node identifier of the node corresponding to the data to be transacted is obtained, a block key can be configured for the node identifier of the node corresponding to the data to be transacted, so that the node of the data to be transacted points to a trusted block in the block chain.
And when the key is configured for the node identifier of the node corresponding to the data to be transacted, different keys are configured for the node identifiers of different nodes to ensure the safety of data transaction. For example, there are 3 nodes corresponding to the data to be traded, and the node identifiers of the three nodes are G1, G2, and G3, respectively. Then, the KEY configured for G1 may be the first KEY1 corresponding to the first block; the KEY configured for G2 may be a second KEY2 corresponding to the second block; the KEY configured for G3 may be the third KEY3 corresponding to the third block.
It should be noted that, in order to ensure data transaction safety, before configuring a key for a node identifier of a node corresponding to data to be transacted, the blockchain management server may perform compliance verification on the data to be transacted through data description information of the data to be transacted, that is, check whether the data to be transacted is compliant, and if the data to be transacted is compliant, configure a key for a node identifier of a node corresponding to the data to be transacted; otherwise, a key is not configured for the node identifier of the node corresponding to the data to be traded, so that the data to be traded which is not in compliance cannot be traded, and the safety of data trading is ensured.
S130, the blockchain management server 13 sends a data transaction notification message to the data receiving end 12.
The data transaction notification information carries data description information of the data to be transacted.
Specifically, after the node of the transaction data points to a trusted block in the block chain, that is, after the key is configured for the node identifier of the node corresponding to the data to be transacted, the block chain management server may perform regional broadcast, that is, send a data transaction notification message to the data receiving end, where the data transaction notification message may carry data description information of the data to be transacted, so that the data receiving end can know whether the current data to be transacted is data required by itself after receiving the data transaction notification message.
If the data to be traded is data required by a certain data receiving terminal, the data receiving terminal can send a data trading request to the blockchain management server to acquire the data required by the data receiving terminal. On the contrary, if the data to be traded is not the data required by the data receiving terminal itself, the data receiving terminal does not send a data trading request to the blockchain management server.
S140, the target data receiving end of the data receiving ends 12 sends a second data transaction request to the blockchain management server.
And the second data transaction request carries the signature of the target data receiving end.
Specifically, if the data to be transacted is data required by a certain data receiving end, that is, a target data receiving end, the target data receiving end may send a second data transaction request to the blockchain management server, and for data transaction security, the target data receiving end also needs to provide its own key, that is, a signature of the target data receiving end.
S150, the blockchain management server 13 binds the signature of the target data receiving end with the key configured for the node identifier of the node corresponding to the data to be transacted, so as to obtain a new key.
Specifically, the signature of the target data receiving end is a key of the target data receiving end, the key distributed by the blockchain management server for the node identifier of the node corresponding to the data to be traded is a key of the data providing end, and the blockchain management server can form a new key by binding the key of the target data receiving end and the key of the data providing end.
And the blockchain management server can send the new key to the data providing end and the target data receiving end, so that in the subsequent step, the target data receiving end can successfully extract the data to be traded from the data providing end by using the new key.
And S160, the data providing terminal 11 and the target data receiving terminal 12 perform data transaction on the data to be transacted through the new key.
Specifically, after obtaining the new key, the target data providing end may send a data obtaining request to the data providing end, where the data obtaining request may carry the new key, and then the target data providing end may obtain the data to be transacted from the data providing end.
According to the technical scheme provided by the embodiment of the application, when the data in the knowledge graph is traded through the block chain, all data in the knowledge graph is not stored in the block chain, but a key is configured for the node identification of the node corresponding to the data to be traded, namely, each node in the knowledge graph is used as an independent object, and each node points to a trusted block in the block chain. And binding a key configured for the node identification of the node corresponding to the data to be traded with the signature of the target data receiving end, and finally trading the data to be traded through a new password. Therefore, by the technical scheme provided by the embodiment of the application, the storage space can be saved, the data transaction efficiency of the data in the knowledge spectrogram is improved, and the data transaction safety is high.
After a detailed description of a data processing system provided by the embodiments of the present application, in a second aspect, a detailed description of a data processing method provided by the embodiments of the present application will be provided.
It should be noted that an execution subject of the data processing method provided in the embodiment of the present application may be a data processing apparatus, where the data processing apparatus may be run in an electronic device, and the electronic device may be a block chain management server.
As shown in fig. 2, a data processing method provided in the embodiment of the present application may specifically include the following steps:
s210, receiving a first data transaction request sent by a data providing terminal.
The first data transaction request carries node identification of a node corresponding to the data to be transacted in the knowledge graph and data description information of the data to be transacted.
Specifically, the data providing end is provided with a knowledge graph, wherein the knowledge graph is a large-scale data asset and has the characteristics of multi-domain relation associativity, frequent data updating and large data magnitude.
A knowledge spectrogram is a multi-relationship graph composed of nodes and edges of different types, where each node represents an entity and each edge represents a relationship between two nodes (which may be referred to as a head node and a tail node) connected by the edge, i.e., indicates that the head entity and the tail entity are connected together by a specific relationship. Each node has data.
When a data providing end wants to perform data transaction on some data in the knowledge graph, a first data transaction request may be sent to the blockchain management server, where the first data transaction request may carry a node identifier of a node corresponding to data to be transacted in the knowledge graph. For example, the data to be traded is data corresponding to the first node, data corresponding to the second node, and data corresponding to the third node, and then the data trading request may carry the node identifier G1 of the first node, the node identifier G2 of the second node, and the node identifier G3 of the third node. That is, the first node, the second node, and the third node are trusted nodes. Nodes except the first node, the second node and the third node in the knowledge graph are nodes which are not trusted, and data corresponding to the nodes which are not trusted cannot be subjected to data transaction, namely, the control of a trusted area is ensured.
In addition, in order to enable the data receiving end to know the data to be transacted in the subsequent steps, the data transaction request can also carry data description information of the data to be transacted.
S220, configuring a key for the node identification of the node corresponding to the data to be traded.
Wherein, the key is a key corresponding to the block in the block chain.
Specifically, in the method adopted by the embodiment of the present application, instead of storing all data in the knowledge graph in the blockchain, each node in the knowledge graph is taken as an independent object, and each node points to a trusted block in the blockchain, wherein each trusted area corresponds to one key, and the keys corresponding to different trusted blocks are different. Therefore, data in the knowledge graph with large data magnitude can be traded efficiently, and the block chain does not need to be subjected to multiple times of full chain confirmation due to frequent changes of the data in the knowledge graph.
Therefore, after receiving the data transaction request, the blockchain management server can analyze the data transaction request to obtain the node identifier of the node corresponding to the data to be transacted carried in the data transaction request and the data description information of the data to be transacted. And after the node identifier of the node corresponding to the data to be transacted is obtained, a block key can be configured for the node identifier of the node corresponding to the data to be transacted, so that the node of the data to be transacted points to a trusted block in the block chain.
And when the key is configured for the node identifier of the node corresponding to the data to be transacted, different keys are configured for the node identifiers of different nodes to ensure the safety of data transaction.
In one embodiment, when the node corresponding to the data to be transacted is a plurality of nodes, configuring the key for the node identification of the node corresponding to the data to be transacted may include the following steps, namely step a1 and step a 2:
step a1, configuring a first key corresponding to the first block for a first node identifier of a first node, where the first node is any one of nodes corresponding to the data to be traded.
Step a2, configuring a second key corresponding to the second block for a second node identifier of a second node, where the second node is a node other than the first node in the nodes corresponding to the data to be transacted, and the second key is different from the first key.
For example, there are 3 nodes corresponding to the data to be traded, and the node identifiers of the three nodes are G1, G2, and G3, respectively. Then, the KEY configured for G1 may be the first KEY1 corresponding to the first block; the KEY configured for G2 may be a second KEY2 corresponding to the second block; the KEY configured for G3 may be a third KEY3 corresponding to the third block, where KEY1, KEY2, and KEY3 are all different.
Moreover, as an implementation manner of the embodiment of the present application, in order to ensure data transaction security, before configuring a key for a node identifier of a node corresponding to data to be transacted, the data processing method further includes the following steps:
and checking whether the data to be traded is in compliance or not through the data description information of the data to be traded.
And when the data to be traded is in compliance, executing a step of configuring a key for the node identification of the node corresponding to the data to be traded.
Specifically, before configuring a key for the node identifier of the node corresponding to the data to be transacted, the blockchain management server may perform compliance verification on the information to be transacted through the data description information of the data to be transacted, that is, check whether the data to be transacted is compliant, and configure a key for the node identifier of the node corresponding to the data to be transacted if the data to be transacted is compliant; otherwise, a key is not configured for the node identifier of the node corresponding to the data to be traded, so that the data to be traded which is not in compliance cannot be traded, and the safety of data trading is ensured.
And S230, sending a data transaction notification message to the data receiving end.
The data transaction notification information carries data description information of the data to be transacted.
Specifically, after the node of the transaction data points to a trusted block in the block chain, that is, after the key is configured for the node identifier of the node corresponding to the data to be transacted, the block chain management server may perform regional broadcast, that is, send a data transaction notification message to the data receiving end, where the data transaction notification message may carry data description information of the data to be transacted, so that the data receiving end can know whether the current data to be transacted is data required by itself after receiving the data transaction notification message.
If the data to be traded is data required by a certain data receiving terminal, the data receiving terminal can send a data trading request to the blockchain management server to acquire the data required by the data receiving terminal. On the contrary, if the data to be traded is not the data required by the data receiving terminal itself, the data receiving terminal does not send a data trading request to the blockchain management server.
S240, receiving a second data transaction request sent by a target data receiving end in the data receiving ends.
And the second data transaction request carries the signature of the target data receiving end.
Specifically, if the data to be transacted is data required by a certain data receiving end, that is, a target data receiving end, the target data receiving end may send a second data transaction request to the blockchain management server, and for data transaction security, the target data receiving end also needs to provide its own key, that is, a signature of the target data receiving end.
In one embodiment, after receiving the data transaction request sent by the target one of the data receiving ends, the data processing method may further include:
and sending data transaction success information to each data receiving end.
The data transaction success information carries a data transaction contract, and the data transaction contract is used for describing the transaction of the information to be transacted between the data providing end and the target data receiving end.
In this embodiment, after receiving the data transaction request sent by the target data receiving end, the blockchain management server may generate a data transaction contract, where the data transaction contract is used to describe that the data providing end and the target data receiving end have transacted the information to be transacted. And the blockchain management server can send data transaction success information to each data receiving end, namely, the data transaction success information is subjected to regional broadcast, so that each data receiving end can know that the data providing end and the target data receiving end perform data transaction on the data to be transacted, and each data receiving end can supervise the transaction, and the openness and the safety of the data transaction are ensured.
And S250, binding the signature and the key of the target data receiving end to obtain a new key, so that the data providing end and the data receiving end perform data transaction through the new key.
Specifically, the signature of the target data receiving end is a key of the target data receiving end, the key distributed by the blockchain management server for the node identifier of the node corresponding to the data to be traded is a key of the data providing end, and the blockchain management server can form a new key by binding the key of the target data receiving end and the key of the data providing end.
In an embodiment, after the signature of the target data receiving end is bound to the key to obtain a new key, the data processing method may further include:
and sending new keys to the data providing end and the target data receiving end so that the target data receiving end sends a data acquisition request to the data providing end and acquires the data to be traded from the data providing end, wherein the data acquisition request carries the new keys.
Specifically, the blockchain management server may send the new key to the data providing end and the target data receiving end, and after the target data providing end obtains the new key, the target data providing end may send a data obtaining request to the data providing end, where the data obtaining request may carry the new key, and the target data providing end may obtain the data to be transacted from the data providing end.
According to the technical scheme provided by the embodiment of the application, when the data in the knowledge graph is traded through the block chain, all data in the knowledge graph is not stored in the block chain, but a key is configured for the node identification of the node corresponding to the data to be traded, namely, each node in the knowledge graph is used as an independent object, and each node points to a trusted block in the block chain. And binding a key configured for the node identification of the node corresponding to the data to be traded with the signature of the target data receiving end, and finally trading the data to be traded through a new password. Therefore, by the technical scheme provided by the embodiment of the application, the data transaction efficiency of the data in the knowledge spectrogram can be improved, and the data transaction safety is high.
For clarity of description, reference will now be made to specific examples.
As shown in fig. 3, there are four nodes in the knowledge-graph, and the nodes of the four nodes are identified as G1, G2, G3 and G4, respectively. If the data to be traded is: data corresponding to the node identified as G1, data corresponding to the node identified as G2, and data corresponding to the node identified as G3, then the block chain management server may configure the KEY original-KEY1 for the node identified as G1, the KEY original-KEY2 for the node identified as G2, and the KEY original-KEY3 for the node identified as G3, without configuring the KEY for the node identified as G4.
When the data of the knowledge-graph is updated, as shown in fig. 4, the knowledge-graph is added with a NEW node, and the node of the NEW node is identified as (NEW) G5. Since the blockchain management server does not distribute the key to the new node, the data receiving end cannot trade the data corresponding to the node, that is, the data receiving end cannot acquire the data corresponding to the node.
According to the description, when the data in the knowledge graph is updated, the data transaction of other trusted nodes is not influenced, and the repeated full-link confirmation of the block chain is not caused, so that the data transaction efficiency can be improved.
Also, the process of trading data assets in a knowledge graph is described in detail below with reference to specific examples.
As shown in fig. 5, the transaction process of the data assets in the knowledge graph involves three-terminal interaction, namely, the data provider, the data consumer, and the transaction platform blockchain manager, the blockchain management server.
Specifically, the data asset provider has a knowledge graph of the to-be-uplink transaction, and sends an uplink request to the transaction platform block chain manager, where the uplink request may carry an identifier of a sub-graph, i.e., a node, corresponding to the to-be-transacted data asset, and data description information of the to-be-transacted data asset.
After receiving the uplink request, the transaction platform blockchain manager analyzes the uplink request to obtain the identifier of the node and the data description information, and performs compliance verification, that is, whether the data asset to be transacted is compliant is verified through the data description information.
If the data assets to be traded are in compliance, the trading platform blockchain manager can issue the KEY of each node for each node according to the graph nodes, namely, the KEY is configured for each node.
After the keys are configured for each node, the transaction platform blockchain manager performs regional broadcast, and at this time, the transaction is ready.
After receiving the regional broadcast, the buyer, i.e. the data asset demander, initiates a transaction request and submits a buyer signature to the transaction platform blockchain manager, i.e. links up the key of the data asset demander.
And after receiving the key of the data asset demander, the transaction platform block chain manager performs signature binding operation, namely binding the key of the data asset demander with the key configured for the node, and further generating a new key combination.
After generating the new key combination, the data asset provider may perform authorization validation. And, the trading platform blockchain manager can perform the on-chain disclosure of the new key combination according to the blockchain logic.
The data asset demander and the data asset provider can conduct data asset transaction through the newly generated key combination and pass the authentication of the key group in the data asset transaction process. Therefore, the data transaction efficiency of the data in the knowledge graph can be improved through the scheme, and the transaction safety of the data assets in the knowledge graph can be improved through generating a new key combination.
