As shown in fig. 1, the data circulation system may include: a data providing system (or data provider) 10; a data consumer (or data consumer) 20 and a data distribution platform 30. Wherein the data providing system 10 is used for providing circulation data; the data circulation platform 30 is used for displaying the circulation data and the associated information (for example, process information, etc.); the data usage system 20 is used to view and filter the circulation data in the data circulation platform 30 and apply for information associated with the circulation data from the data providing system 10. For example, the data circulation platform 30 may be a data mart in which the data providing system 10 may present data to be circulated for the data using system 20 to select the use data.

Specifically, the data providing system 10, the data using system 20, and the data circulation platform 30 may serve as a block chain node, and access the block chain 40, so that information associated with circulating data may be directly acquired; or access the blockchain through an interactive interface or an interactive interface provided by the blockchain link points to acquire information associated with the circulating data.
Example one
Fig. 2 is a flowchart of a block chain-based process management method according to an embodiment of the present invention. The process management method is executed by a process management system based on a block chain, and the process management system can be matched with the data circulation system to complete the circulation process of data in the data circulation platform shown in fig. 1 and manage corresponding process information.
As shown in fig. 2, the flow management method applied to the blockchain node may include the following steps:
step S201, receiving a data operation request, where the data operation request is a request for using streaming data.
The circulation data may be data circulated in the data circulation system shown in fig. 1, and may also be data displayed in the data circulation platform 30.
The data operation request may be a data upload request initiated by the blockchain node when the data providing system (or the data provider) 10 issues the circulation data to the data circulation platform 30; a rights management request initiated to the blockchain node when the data usage system (or data consumer) 20 requests the data providing system (or data provider) 10 for authorization management; and/or a data verification request initiated from the blockchain node when the data usage system (or data consumer) 20 requests the data providing system (or data provider) 10 to use the circulation data.
On one hand, a data provider or a data user can be used as a block chain node and directly broadcast in the block chain, and correspondingly, the block generation node receives and processes the data operation request; on the other hand, the data provider or the data user may also send a data operation request to the blockchain node through an interactive interface (e.g., a browser interface or a client interface) provided by the blockchain node or an interactive interface of the lightweight node, where the blockchain node converts the received data operation request into a data operation request that can be processed by the blockchain node, and broadcasts the data operation request to the blockchain network, so that the blockchain generation node receives and processes the data operation request.
Step S202, processing the data operation request to execute the operation of using the circulation data.
And if the data operation request is a data uploading request, executing the data uploading request to acquire fingerprint information and meta (meta) information of the circulating data, and uplink-storing the fingerprint information and the meta information of the circulating data, wherein the meta (meta) information comprises description information and a storage position of the circulating data.
The fingerprint information of the circulation data can be calculated by the data provider, and can also be calculated by a third-party device through a specific algorithm. In a preferred embodiment, to reduce the computational load of the data provider, the fingerprint information may instead be computed by a third party device trusted by the data provider. The third-party device may be a server or a server cluster capable of providing a trusted computing environment, supporting complex algorithmic computing functionality.
And if the data operation request is an authority management request, executing the authority management request, associating the identity of the data user with the identity of the circulating data, and performing uplink storage. The identification of the circulation data can be product identification, description information or fingerprint information of the circulation data.
And if the data operation request is a data verification request, executing the data verification request, verifying the fingerprint information of the circulating data and the authority information of the data user, and feeding back the result of the authority verification of the circulating data.
Step S203, determining and uplink storing the flow information of the circulation data based on the usage operation of the circulation data.
If the data operation request is a data uploading request, based on the uploading operation of the circulation data, determining that the flow information of the uploading operation of the circulation data is to upload fingerprint information and meta (meta) information of the circulation data to a block chain and the like, and uploading and storing the flow information.
And if the data operation request is an authority management request, determining that the process information of the authority application operation of the data is an approval task of one or more data providers based on the authority application operation of the circulating data, and uploading and storing the process information. And the approval task is to authorize a data user corresponding to the identity associated with the fingerprint information of the circulation data so as to confirm that the data user can legally use the circulation data.
If the data operation request is a data verification request, based on the verification operation of the circulation data, determining that the flow information of the verification operation of the circulation data is fingerprint information of the circulation data and authority information of the data user, feeding back the result of the authority verification of the circulation data, and finally, uploading and storing the flow information.
The present embodiment first performs a usage operation on the traffic data by processing a data operation request; then, based on the use operation of the circulation data, determining the flow information of the circulation data; and finally, uplink storing the determined flow information of the circulation data. The technical scheme is based on the block chain, the related circulation information is determined when the circulation data are used, and the flow management method can display the flow information of the circulation data on the block chain, so that decentralized flow management is realized, and a fair, fair and transparent data circulation process is realized.
Example two
Fig. 3 is a flowchart of a block chain-based process management method according to a second embodiment of the present invention, where the second embodiment of the present invention performs optimization and improvement on the basis of the technical solutions of the foregoing embodiments. The method comprises the steps that the step of determining and uploading process information for storing the circulation data based on the use operation of the circulation data is further refined into the step of calling a process management intelligent contract based on the use operation of the circulation data so as to generate a process creation request; processing the flow creation request to generate flow information of the circulation data; and the uplink stores the flow information.
A block chain-based process management method as shown in fig. 3 includes the following steps:
step S301, receiving a data operation request, where the data operation request is a request for using streaming data.
Step S302, processing the data operation request to execute the operation of using the circulation data.
Step S303, based on the use operation of the circulation data, calling a flow management intelligent contract to generate a flow creation request.
Step S304, the flow creation request is processed to generate flow information of the circulation data.
In step S305, the uplink stores the process information.
When the data provider issues the circulation data to the data circulation platform, a data uploading request is initiated. And after the block generation node receives the data uploading request, the data uploading request is executed by calling a data uploading intelligent contract so as to acquire the fingerprint information and the data introduction information of the circulating data, and the circulating data is linked and stored. Then, the data upload intelligent contract calls a process management intelligent contract to generate a process creation request. Then, based on the executed data uploading operation, the flow information of the circulation data is generated. And finally, storing the flow information in a block chain.
When the data user browses the needed circulation data on the data circulation platform, the data user initiates a permission management request to the data provider. After the block generation node receives the authority management request, the authority management request is executed by calling an intelligent contract for authority management so as to associate the identity of the data user with the identity (preferably, fingerprint information) of the circulating data, and the circulating data is uplink stored. The rights management intelligent contract then invokes a process management intelligent contract to generate a process creation request. Then, based on the executed authority management operation, flow information of the circulation data is generated. And finally, storing the flow information in a block chain.
When a data user has the right to use the circulation data, a data verification request needs to be sent to a data provider before using the circulation data. After the block generation node receives the data verification request, a data verification intelligent contract is called to execute the data verification request so as to verify the fingerprint information of the streaming data and the authority information of a data user; and feeding back the result of the authority verification of the circulation data. And when the fingerprint information of the circulation data and the authority information of the data user are successfully verified, feeding back a verification result of allowing the circulation data to be used, and calling a flow management intelligent contract to generate a flow creation request. Then, based on the executed authority management operation, flow information of the circulation data is generated. And finally, storing the flow information in a block chain. When the circulation data is tampered, the fingerprint information of the circulation data changes, which results in unsuccessful fingerprint verification; if the data user does not have the right to use the distributed data, the right verification will be unsuccessful. Thus, when the verification of the fingerprint information of the circulation data or the authority information of the data user is unsuccessful, the verification result that the circulation data is not allowed to be used is fed back.
In this embodiment, the triggering and calling of the intelligent contract for flow management is triggered through the intelligent contract corresponding to the data operation request, so that flow information corresponding to the use operation of the circulating data is established in the circulation period of the circulating data, and the flow information is stored in a chain manner, thereby realizing decentralized flow management and further realizing a fair, fair and transparent data circulation process.
EXAMPLE III
Fig. 4 is a flowchart of a block chain-based process management method according to a third embodiment of the present invention, and this embodiment optimizes a technical solution based on the second embodiment. And after the process information is uplink stored, receiving a polling request of the process approval system, and feeding back a corresponding process approval task to the corresponding process approval system.
The process approval system can be a data providing system or a specially-arranged process approval system, for example, when the data providing system issues the circulation data to the data circulation platform, the specially-arranged process approval system can audit the process so as to twist the uploading process of the circulation data to the next task or finish the process; under the condition that the data using system requests the data providing system for authorization management, the data providing party can verify the authority application so as to authorize the data using party; in the case where the data usage system requests the data providing system to use the circulation data, the usage right may be verified by the data provider.
Step S401, receiving a data operation request, where the data operation request is a request for using streaming data.
Step S402, processing the data operation request to execute the usage operation on the circulation data.
And step S403, based on the use operation of the circulation data, calling a flow management intelligent contract to generate a flow creation request.
Step S404, processing the flow creation request to generate flow information of the circulation data.
In step S405, the uplink stores the process information.
Step S406, receiving a process management polling request sent by the process approval system.
Specifically, the process approval system can send a process management polling request to the blockchain in a real-time or timed manner; the block generating node receives the process management poll request.
Step S407, processing the process management polling request, so as to feed back the process approval task of the circulation data to the process approval system according to the process information.
And after receiving the process management polling request, processing the process management polling request by calling a process management intelligent contract so as to feed back a process approval task of circulating data to the process approval system according to the process information. And then, under the condition that the process approval task is received, the process approval system initiates a process approval request.
Step S408, receiving a process approval request initiated by the process approval system.
Step S409, processing the flow approval request to examine the flow of the circulation data.
And step S410, under the condition that the process passes the audit, calling the process management intelligent contract to twist the process of the circulation data to the next task or end the process according to the process information.
Under the condition of receiving the process approval task, the process approval system sends a process approval request to a block chain, and a block generates a node to receive the process approval request; and processing the process approval request by calling the process approval intelligent contract so as to examine the operation on the process of the circulating data. After the process approval passes, a process management intelligence contract is invoked to turn the process back to the next task in the process information or to end the process.
Of course, in the case of receiving the process approval request, the present invention is not limited to processing the process approval request by invoking the process approval intelligent contract, but may also process the process approval request by invoking the intelligent contract corresponding to the data operation request.
Specifically, for example, the data using system requests the data providing system for authorization management, and according to the flow information, the authorization task of the circulating data is fed back to the corresponding data providing system. The data provider receives the authorization task and sends an authority management request to a block chain, and a block generation node receives the authority management request; and processing the authority application request by calling the authority management intelligent contract so as to authorize the authority of the data user. After the authorization is successful, a process management intelligence contract is invoked to either turn the process back to the next task in the process information or end the process.
In this embodiment, the process information of each data flow in the data flow platform can be obtained in time by polling the intelligent contract for process management in real time or at regular time through the process approval system, so as to realize a fair, fair and transparent data flow process.
Example four
Different intelligent contracts on the block chain are mutually called through a preset interface, but for the safety of calling, the intelligent contracts are only called by the preset interface on the block chain, and other interfaces do not have the authority of calling the intelligent contracts. Therefore, on the basis of the foregoing embodiments, in order to prevent the flow management intelligent contract from being maliciously attacked, that is, the preset interface on the non-blockchain calls the flow management intelligent contract, the present embodiment may verify the authority of calling the preset interface of the flow management intelligent contract before the step of processing the flow creation request.
Therefore, the technical scheme adopted by the embodiment is as follows: and calling a process management intelligent contract through a preset interface based on the use operation of the circulation data, and performing authority verification on the preset interface before executing the step of processing the process creation request. Specifically, if the permission verification is successful, the flow creation request is processed to generate flow information of the circulation data; otherwise, no operation is performed.

In step S513, the rights management intelligent contract triggers the process management intelligent contract to generate a process creation request.
Step S514, authenticating the preset interface for calling the process management intelligent contract, if the preset interface passes, creating and recording the process information of the circulation data on the block chain 40, otherwise, ending the process.
In step S515, the data providing system 20 polls the process management and invokes the process management intelligent contract to obtain the process information.
Step S516, according to the process information, feeding back the authorization task of the circulating data to the data providing system 10.
Step S517, the data providing system 10 accesses the block chain 40, calls the intelligent contract for authority management, and performs the authority authorization operation.
