Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
Fig. 1 is a block chain system architecture diagram disclosed in this embodiment, and it should be noted that fig. 1 is only a system architecture diagram disclosed in some embodiments of the present application, and other schematic diagrams obtained by optimizing or deforming based on fig. 1 are all within the protection scope of the present application.
The system architecture shown in fig. 1 comprises a plurality of nodes, n nodes are shown in the figure, the nodes can be interconnected through a network, the nodes can be represented as servers, intermediate devices, terminal devices and the like, and each node can provide data transceiving service of the internet of things for the rest nodes in the coverage area of the network. Typically, a node corresponds to one or more users, and the node responds to a request or a trigger instruction of the user to complete the behavior trace construction based on the service data.
Example 2
Based on the system architecture of fig. 1, fig. 2 shows an embodiment flow of a blockchain-based behavior trace construction method according to an embodiment of the present application, including:
and S11, signing the service data by the node user by using the user digital certificate.
Specifically, the node user holds a unique personal digital identity different from the machine digital certificate, and the user digital certificate of the node user is issued by an organization or a chain where the node user belongs to, so that the uniqueness and privacy of the identity of the node user on the chain are ensured.
In a further embodiment, the digital user certificate may be generated by using a cryptography technique, for example, in a public-private key pair manner, the private key is held by the node user, the public key is broadcast on the chain, the node user signs the service data by using the private key corresponding to the digital user certificate, and other users on the chain can verify the authenticity and validity of the signature of the current node user by using the corresponding public key.
And S12, the node writes the user signature information and the service data into the block together, wherein the block represents different versions of the service data.
Specifically, each node on the chain receives and verifies an update request of the node user for the service data, generates blockchain transaction data with the service data by user signature information provided by the node user, and stores the transaction data on the blockchain as historical traces of the data. The personal identity information is introduced by using the user digital certificate, so that the data endorsement process corresponds to the actual behavior, and the personal actual behavior is organically related to the data endorsement process.
In a further embodiment, the node may collect signature time and signature place corresponding to the user signature, generate transaction data according to the user signature information, the signature time, the signature place and the service data, and write the transaction data into the block, so as to ensure that the space-time background of the data is matched with the real service activity, and the service data will obtain more real and reliable endorsement trace.
In a further embodiment, the nodes also use the machine digital certificates to endorse and sign the transaction data, so that each transaction has a unique blockchain transaction record and is jointly verified and stored by a plurality of nodes, thereby ensuring the security and tamper resistance of the data.
Since each change of the data record corresponds to a unique blockchain transaction, there may be multiple versions of the data change trace, and the transaction information may be distributed over multiple blocks, forming a chained transaction data change history.
S13, reading the blocks on the chain, and constructing behavior traces of users on the service data according to the user signature information in the blocks.
When a node user on the chain reads the data on the chain, the data change trace including, for example, the identity information, time, place and the like of the participating user can be acquired, so that a clear user behavior trace is constructed, and the user can accurately know the change process of the data.
In a further embodiment, the node user information based on the behavior trace can also construct a knowledge graph comprising multiple items of information such as the participating user, the space-time background and the event, and the graph can reflect the relationship and the behavior trace among the participants more truly and credibly, which further supports the deep utilization and mining of the data and provides a richer and reliable data basis for the application in various fields.
The knowledge graph can be established by adopting various conventional graph construction models or methods, and the application is not limited in any way.
Example 3
Referring to fig. 3, the above behavior trace construction method is further described by taking the initiation application form as an example.
The Zhang III and Li IV in FIG. 3 are members of the same organization, which constructs the connection of each member node based on the blockchain, and each member holds a unique user digital certificate for signing and endorsing when the on-chain business data is changed.
In the example of fig. 3, the form application is created by the third party, the first party applies for the form and agrees, the content of the form application forms service data, the digital certificate of the Zhang Sanyong user signs the form, and then the node where the third party is located records the identity information, the event, the initiation time and the initiation place of the third party, generates the transaction 5532 illustrated in fig. 3 with the data content of the form application, writes the transaction data into a block together with other transaction data, and generates a block 609. Similarly, a form initiated by four pairs of Zhang Sans is initially verified, the form is signed and a transaction 6703 is generated, written to block with other transaction data, and block 617 is generated. Blocks 609 and 617 together form a change history for the form application on the blockchain, and ordered blocks on the chain can be regarded as different versions of the form application, from which information such as identity information, signature time, signature place, etc. of Zhang three and Li four can be obtained when the on-chain user reads the on-chain data, thereby constructing a behavior trace of the business data of the form application.
Example 4
FIG. 4 illustrates, on the basis of FIG. 3, the process of building behavioral traces for a form application from blocks of a blockchain. As shown in fig. 4, a form application is created for Zhang San, a four-in-one form application is first reviewed, a five-in-one form application is reviewed, three persons sign endorsed on the form by using own user digital certificates respectively at a capital company, a capital company and a Guangzhou headquarter, different block transactions are correspondingly generated by the nodes where the three persons are located, the block transactions are written into different blocks and stored on a chain, the different block transactions reflect the signing endorsement behaviors of the three persons on the form application, the ordered blocks on the chain reflect different versions of the form application, for example, the block generated by the node where Zhang Sanis located corresponds to the form for initiating the application, the block generated by the node where Lisi is located corresponds to the form for applying with the signature of the four-in-one primary nuclei, and the block generated by the node where Wang is located corresponds to the form for signing the application on the basis of the four-in-one primary nuclei. The information is extracted from the three blocks to construct the behavior trace of the form, and the behavior trace intuitively reflects the real business behavior of the three persons on the same form in different time and space as shown in the right part of fig. 4.
In a more specific example aspect, nodes where Zhang three, li four and Wang five are located can also use node digital certificates (i.e. machine digital certificates) to endorse forms and generate transactions which are different from the three-person signature and write into blocks together with other transaction data, so that service data is doubly protected by a trust chain of real behaviors and a machine trust chain, and is different from the traditional single-chain form only with the machine trust chain.
The scheme provided by the embodiment can start from any version of the business data and inquire out the participants of the business data and the corresponding behaviors of the participants.
Referring to fig. 5, a process of expanding and constructing a complete system-wide behavior graph based on behavior traces of users and service data on a chain is shown, and still taking Zhang san, li san and Wang san as examples, the behavior traces of other service data in which three persons participate can be constructed from different blocks constructed by different users, besides the behavior traces of the same service data in which three persons participate, based on block chain data. As shown in fig. 5, the king five initiates other form applications in addition to checking the form application initiated by Zhang san, and is initially checked by the buddha's warrior; the other form applications initiated by Zhang San are initially examined by the King Kong, so that the complete behavior patterns of different business data participated by the users on the chain can be constructed according to the transaction blocks recorded with different user signature endorsements on the chain.
Example 5
Based on the network topology shown in embodiment 1, the embodiment of the present application further provides a system for constructing a behavior trace based on a blockchain, which includes a first node and a second node, where the first node is a node where a user is located on a chain, and the second node may be a node where a user is located on a chain, or may be a server, a terminal device, or the like, which has a function of managing a node where a user is located on a chain, and fig. 6 and fig. 7 respectively illustrate different embodiments of the system.
The first node is configured to respond to the signature of the node user on the service data, and complete each step of generating the transaction data and the block in each embodiment.
The second node is used for reading the block on the chain and constructing the behavior trace of the user on the service data according to the user signature information in the block. It is easy to understand that the second node here may be a node where other users on the chain are located, or may be a manager that uses a server or terminal device to read data on the chain to construct a service trace.
