Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The data report processing method provided by the embodiment of the application can be applied to the application environment shown in the figure 1. Wherein the terminal 102 communicates with the server 104 via a network. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104 or may be located on a cloud or other network server. In this implementation environment, the data storage manner in the server 104 may store report information generated by the application in a blockchain storage manner. The server 104, as a node joining the blockchain, can package report information generated by its installed application system to form a new block of the blockchain by a consensus mechanism, join the new block into the blockchain, and send the information of the new block to other nodes in the blockchain by broadcasting. In the implementation environment, in the situation that report information needs to be acquired, the server 104 responds to a report extraction instruction of the terminal 102, and performs matching search with historical report information stored in a blockchain block accessed by the server 104 based on target report information carried in the report extraction instruction; and if the historical report information stored in the block chain block is judged to be consistent with the target report information carried in the instruction, selecting the block chain block as a candidate block. Further, the report extraction instruction received by the server 104 may also carry time interval information; and based on the time interval information, performing secondary screening on the candidate blocks obtained by the primary screening to obtain target blocks with the block creation time matched with the time interval information. Then, based on the target block obtained by screening, the server 104 further obtains a timestamp formed when the block is created, and forms a time-associated path of the target report information according to the timestamp. Finally, based on the time correlation path, the server 104 extracts and sorts the report information in the target block according to the time dimension, and finally, the sorted target report information can accurately reflect the change condition of the data in the target report information in the set time interval. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices, where the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.
In one embodiment, as shown in fig. 2, a data report processing method is provided, and the method is applied to the server 104 in fig. 1 for illustration, and includes the following steps:
step 202, responding to a report extraction instruction, and acquiring target report information carried by the report extraction instruction.
In an embodiment, the report extraction instruction is instruction information that acquires historical report information that has been generated and stored into the blockchain in response to an operation of the target object in the terminal interactive interface. The target report information is information content used for describing the target report to be extracted in the report extraction instruction.
In an exemplary embodiment, the server obtains an interaction instruction of the operation object through an interaction operation interface of the terminal, triggers a corresponding report extraction instruction, sends the report extraction instruction to the server, performs necessary analysis processing on the report extraction instruction at the server to obtain target report information carried in the report extraction instruction, and the server can extract the corresponding report information from the historical report information stored in the blockchain based on the target report information and returns the report information to the terminal.
And 204, accessing the blockchain, and carrying out matching search according to the target report information and the historical report information stored in the blocks in the blockchain to obtain a plurality of candidate blocks corresponding to the report extraction instruction.
The Blockchain (Blockchain) applied in the embodiment is a distributed shared ledger and database, and has the characteristics of decentralization, non-falsification, whole trace, traceability, collective maintenance, disclosure transparency and the like. The foregoing features ensure the authenticity of the stored data in the blockchain blocks. In the block of the block chain in the embodiment, the historical report information generated by the application system in the life cycle is stored. In the embodiment, when the collected historical report information is packaged to form the blocks in the blockchain, the content of the historical report information needs to be encrypted, then the corresponding ciphertext data is formed, and the blocks in the blockchain are formed by packaging.
In an exemplary embodiment, a server with an application system background may be added to a blockchain as a new node, and in the adding process, a request is first sent to other nodes in the blockchain, so that the server can successfully establish a connection with the other nodes. If the other nodes agree, then both nodes successfully establish a connection. In a blockchain network, nodes must be connected by a network protocol, such as the P2P (Peer-to-Peer) protocol. In a P2P network, each node is peer-to-peer, and can send and receive data to and from each other. Furthermore, the server can obtain all the block bodies in the block chain and the history report information stored in the block bodies after establishing connection with other nodes as newly added nodes. After the server is successfully accessed to the blockchain and passes node authentication of the blockchain, matching search is carried out on the historical report information stored in the blockchain based on the target report information obtained by analyzing the report extraction instruction, so that tracing of the target report information is realized. In the matching search of the embodiment, since the historical report information stored in the block is encrypted to obtain ciphertext data, before the matching search is performed, the same encryption process can be performed on the target report information, similarity calculation is performed on two encrypted data in a text similarity calculation mode, a higher similarity threshold value is set, and if the calculated similarity value can meet the similarity threshold value, the ciphertext data in the current block is judged to be ciphertext of the target report information; the blockchain blocks storing the corresponding ciphertext data are marked as candidate blocks.
And step 206, screening the plurality of candidate blocks according to the time interval information carried by the report extraction instruction and the time stamp in the candidate blocks to obtain the target block.
In an embodiment, the time interval information is used to describe a time interval formed between a given start time node and end time node, wherein a specific time value is a description of the time generated for the target report information. That is, according to the time interval information carried in the report instruction, the data change of the target report information in the set time interval can be acquired from the blockchain. In an embodiment, the timestamp in the candidate block is the only time information when the encrypted historical report information is packed to form a new block of the blockchain, and the time information is stored in the block header of the block.
In an embodiment, after performing primary screening based on target report information and historical report information stored in a block chain block to obtain candidate blocks containing the same report information, a server extracts time interval information in report extraction information sent by a terminal to obtain a start time node and an end time node of the time interval information, performs second-round screening on the candidate blocks based on a time interval formed by the two nodes and a timestamp in a block head of the candidate block, and generates time of the screened target blocks within a time range formed by the time interval information. Before the embodiment performs the second round of screening, the embodiment can convert the starting time node and the ending time node of the time interval information through timestamp conversion tools such as Unix timestamp and the like due to the particularity of the data structure of the timestamp of the candidate block, the data format with the same timestamp is formed, and whether the timestamp of the candidate block falls between the sequence numbers is judged according to the starting character string sequence numbers and the ending character string sequence numbers corresponding to the starting time node and the ending time node, so that whether the candidate block is a target block is judged. In contrast, in the embodiment, the timestamp may be converted into the time information in the normal time format by using a timestamp conversion tool such as Unix timestamp, and whether the time information falls into the time interval is determined, so as to determine whether the candidate block is the target block.
Step 208, according to the time stamp in the target block, a time-associated path is constructed.
In an embodiment, the time-associated path is based on a plurality of time node information, and forms a path according to the sequence of the time nodes; the time node information may be converted by a time stamp.
In an embodiment, the time stamps of the candidate blocks are filtered through time interval information to obtain target blocks, then time stamps are extracted from the block heads of all the target blocks, a plurality of time stamps obtained by extraction are converted into time information in a normal time format through a time stamp conversion tool such as Unix time stamp, and the obtained time information is the time generated by the block, and meanwhile, the time node can also reflect that the data content of the target data report changes in the report. The service forms time node sequences according to the sequence of the time nodes corresponding to all the time stamps, and the time nodes are connected in series in a coordinate axis mode and the like, so that corresponding time correlation paths can be obtained.
And step 210, extracting target report information from the target block according to the time correlation path.
The embodiment of the invention is characterized in that after a time correlation path is formed based on the time stamp of the target block, the data content of the target report information is extracted from the target block, the data content of the target report information is decrypted to obtain a corresponding data plaintext, meanwhile, the data plaintext is correlated with the time node after the time stamp conversion, the data plaintext is ordered according to the sequence of the time nodes in the time correlation path based on the correlation relationship between the data plaintext and the time node, finally, the obtained data content records of the target report in different time intervals can also more intuitively and clearly reflect the change of the data content in the data report along with the change of time, and the data content is convenient to track.
The data report processing method in the embodiment is based on report extraction instructions, extracts and calls the stored historical report information in a block chain mode, replaces a manual data source tracing mode in the traditional scheme, saves labor cost and time cost, and is high in processing efficiency; when searching and screening target report information, the method firstly performs primary screening based on the target report information in the report extraction instruction to obtain candidate blocks storing corresponding report information, and then performs secondary screening based on time interval information in the report extraction instruction and time stamps carried by the candidate blocks to obtain target blocks; the time correlation path is formed based on the time stamp carried by the target block, so that the target report information is obtained through extraction, and the change condition of report data can be reflected more intuitively; and the reliability of the finally extracted target report information is higher by combining the characteristic that the blockchain cannot be tampered.
In one embodiment, as shown in fig. 3, the data report processing method may further include:
step 302, obtaining historical report information.
Illustratively, in an embodiment, the data content of the data report in the application system may be obtained by automating data collection, database connection, and by way of a Web service or calling an API interface. For example, in the embodiment, the data change condition of the data report in the application system can be directly obtained through the API interface, and the real-time data acquisition and processing can be realized through the API interface, and meanwhile, the data report can be integrated with other application programs. It should be noted that in the embodiment, an appropriate data acquisition mode needs to be selected according to a specific scene and requirements, and effective management and maintenance are performed on data, so as to ensure accuracy and reliability of the data.
Step 304, the history report information is hashed to obtain an intermediate state hash character string.
The intermediate Hash string is a string of binary values with a fixed length, which is calculated by a Hash algorithm, and in an embodiment, the Hash algorithm can map binary values with any length to binary values with a shorter fixed length, and the small binary values are called Hash values. Hash values are a unique and extremely compact representation of a piece of data.
Illustratively, in the embodiment, the server is used as a blockchain node, and after acquiring a newly generated data report or an updated data report, the data content in the data table can be verified through a necessary verification process. After the verification is passed, the server will first encrypt the report data. Because the Merkle (Merkle) tree is an essential component of the blockchain, all encrypted report data is firstly converted into hash values based on the characteristics of the Merkle tree and recorded in the father node of the Merkle tree of the operation record; then, all hash values recorded by the operation are pairwise captured, the hash value of the sum of the hash values is calculated, and the hash values of the two captured pairs are recorded in a common father node; the process of pairwise computing the hash value records is repeated until the final total hash value is generated, and the block performs hash operation on the final hash value again and then records the final hash value into the head as the ID of the block.
And step 306, obtaining the calculation difficulty value of the intermediate state hash character string according to the hash operation, and generating the workload certification of the block.
The workload certification in the embodiment belongs to a consensus mechanism, and is used for proving whether the nodes in the blockchain complete the certification of a certain amount of work when forming a new block.
Illustratively, in the embodiment, each time a new block is generated, after the data content of report data for uplink storage is selected, the version number, the timestamp and the difficulty value in the block header need to be filled, and a root hash of the corresponding Merkle tree is generated. These values are unique and fixed after the data content of the report data is selected, and the only value that can be changed is the random number (Nonce). The server is used as a node of the block chain, and two SHA256 algorithms for calculating the block head of the whole new block are required according to the difficulty value, and the obtained hash result is smaller than a preset threshold. The server can find the corresponding random number only by continuously trying and enumerating according to the pseudo-randomness of the period number SHA256 algorithm, and the workload of the server can be proved.
And 308, generating a block corresponding to the historical report information according to the workload certification and the intermediate hash character string.
For example, the server needs to obtain the block information of the last block of the new block before packaging to form the new block, where the block information of the last block mainly includes the last block ID. And calculating the current block ID and the last block ID according to the steps to realize the linking function of the blocks. Finally, the server forms a block header of the new block based on the previous block ID, the current block ID, the root hash of the Merkle tree, the timestamp, the version number, and the workload proof; and encrypting and packaging the acquired report data to form a block body, combining the block head and the block body to obtain a new block, and accessing the new block into a block chain.
In the embodiment, report data is stored in a block chain mode, each block can store the report data content in a specific time, and a safe and reliable chain is constructed in a cryptography mode to form a non-tamperable storage structure, so that the safety of the data is improved.
In one embodiment, before generating the block corresponding to the historical report information according to the workload certification and the intermediate state hash character string, the method may further include a process of verifying the electronic signature of the intermediate state hash character string, so that generating the new block in the blockchain in the embodiment method may include the following steps:
step one, an electronic signature corresponding to the intermediate hash character string is obtained.
And step two, if the electronic signature and the intermediate state hash character string pass through the verification of the nodes in the block chain, generating a block corresponding to the historical report information according to the workload certification and the intermediate state hash character string.
The electronic signature is signature information formed by encrypting report data subjected to hash operation through a private key generated by an asymmetric encryption algorithm, so that the signature information contains related information of hash character strings of the data report.
Illustratively, in an embodiment the server needs to check the validity and validity of the report data obtained before it is packaged as a blockchain link to form a blockchain chunk. Aiming at the validity verification in the embodiment, firstly, the blockchain in the embodiment adopts an asymmetric encryption mode to form a public key and a private key; wherein, in a node of the blockchain, its generated public key is public to other nodes in the blockchain, and its generated private key is private to the blockchain node. Furthermore, when the server is used as a block chain link point to package the report data to form a block in the block chain, firstly, the hash operation is required to be performed on the report data to generate a hash character string, and the hash character string is recorded as an intermediate state hash character string. And then the server encrypts the hash character string according to the locally stored private key to form signature information. After the signature encryption is completed by the server, other nodes in the blockchain are broadcasted, wherein the broadcasted content is report data obtained through initial acquisition and signature information formed through private key encryption. After receiving the broadcast message, other nodes can decrypt the signature information in the broadcast message by utilizing the public key which is generated and broadcast in advance by the node to obtain a corresponding hash character string, meanwhile, the other nodes synchronously carry out hash operation on report data in the broadcast message to obtain another hash character string, the two hash character strings are compared, whether the two hash character strings are consistent or not is judged, if so, the data transmission is proved to be correct, and the verification is passed. If the transaction information is inconsistent, the transaction information is proved to be changed, and verification cannot be passed. The method of the embodiment effectively solves the problem of node verification consistency through a partial symmetric encryption mode.
In one embodiment, the method performs a matching search according to target report information and historical report information stored in blocks in a block chain to obtain a plurality of candidate blocks corresponding to report extraction instructions, and the method includes the following steps:
step one, a history hash character string corresponding to the history report information is obtained.
And secondly, carrying out hash operation on the target report information in the report extraction instruction to obtain a target hash character string corresponding to the target report information.
And thirdly, searching and obtaining candidate blocks corresponding to the report form extraction instructions from the block matching corresponding to the historical hash character strings according to the fact that the historical hash character strings and the target hash character strings are identical.
Illustratively, in the process of extracting report data based on the target report information carried in the report extraction instruction in the embodiment, similar to the process of packaging the report data to form the blocks in the blockchain, the consistency of the data needs to be checked in a comparison manner. For example, in the embodiment, the target report information may select the topic name and part of the core attribute fields of the data report, and hash the character strings formed by the combination to obtain the target hash character string of the target report information. Correspondingly, when the block chain stores the report data, a corresponding index can be generated based on the report data in the block, and the source report topic name and part of core attribute fields of the report data in the block are combined to form index information. And when matching search is carried out, comparing the target hash character string with the hash character string obtained after hash operation is carried out on the index information, and if the comparison result is the same as the target hash character string, taking the block corresponding to the index information as a candidate block corresponding to the report extraction instruction. According to the embodiment, the matching search efficiency is improved on one hand by setting the index and comparing the hash strings; on the other hand, the consistency of the data before and after the data is ensured, and related information is prevented from being tampered maliciously.
In one embodiment, in the method, according to time interval information carried by a report extraction instruction and a timestamp in a candidate block, screening a plurality of candidate blocks to obtain a target block includes the following steps:
step one, time interval information in the report extraction instruction and a time stamp in the candidate block are obtained.
And step two, binding a hash value obtained by hash operation of the data report information corresponding to the report extraction instruction with the time interval information to form an interval time stamp.
And thirdly, screening the target block from the candidate blocks according to the time stamp in the candidate block and the interval time stamp.
In the embodiment, since the time stamp in the candidate block is obtained by performing hash operation on report data to be stored in the block when the block is formed, and based on the hash string, a time stamp request is sent out by a time stamp server, the time stamp server signs the hash string and the time record, and the obtained time stamp is generated. This timestamp is bound to the report data and stored in the block. Based on the feature that the time stamp is bound with the report data, in the embodiment, after the time interval information of the screened report data is extracted from the report extraction instruction, hash operation is performed on the target report information to obtain a corresponding hash value, and the hash value and the time interval information are sent to a time stamp server to obtain the corresponding time stamp. For example, the embodiment may select the start time and the end time in the time interval information as the time record of the target report, and send the time record to the time stamp server to obtain the time stamp. It should be noted that, in the embodiment, when the data report is generated, hash operation may be immediately performed on the data in the report, and the hash operation is sent to the timestamp server according to the time of generating the data report, so as to obtain the corresponding timestamp; because the binding relation exists between the time stamp and the report data, when the data report is called, the binding relation between the report and the time stamp can be directly utilized to directly acquire the time stamp as a starting time node or an ending time node of the time interval information. The server screens the time stamp in the candidate block according to the starting time stamp and the ending time stamp; the time stamp can prove the context between the blocks, and then the time stamp falls into the block between the start time stamp and the end time stamp, and the target block is determined. In the embodiment, the non-tamperable data of the time stamp is utilized, the blocks are screened through the time stamp, and the reliability of the obtained result is higher.
In one embodiment, the data report processing method may further include the steps of:
step one, obtaining a time correlation path corresponding to target report information.
And step two, pushing the target report information according to the time information corresponding to the target report information in the time correlation path.
Illustratively, the time-associated path in the embodiment can describe the life cycle of one data report, and meanwhile, the embodiment obtains the change content of the data in the target report in the life cycle from the blockchain based on the time-associated path. After the server obtains the change content of the report data, the server pushes the data report corresponding to different time to the terminal according to the time information described by the time correlation path and the time sequence, and the data report is visually displayed through the terminal.

firstly, data information which is generated for the first time by each business function in a financial transaction system and comprises target object information, operation time, a storage system, a target report and the like is packaged into blocks in a block chain, and a time stamp of a new block is generated based on the operation time. Then, the data report after the change is stored in the chain structure of the blockchain for any information or data change of the report.
Then, when the report data stored in the blockchain is called, matching screening can be performed according to specific report information and the time stamp of the block storing the report information, so as to realize the analysis of the data source of any report tracking analysis or the analysis of the range and influence of the change of certain data.
Specifically, in the embodiment, the report extraction instruction is responded, and based on target report information carried in the report extraction instruction, matching search is performed with history report information stored in an accessed blockchain block; and if the historical report information stored in the block chain block is judged to be consistent with the target report information carried in the instruction, selecting the block chain block as a candidate block. Further, the received report extraction instruction can also carry time interval information; and based on the time interval information, performing secondary screening on the candidate blocks obtained by the primary screening to obtain target blocks with the block creation time matched with the time interval information. And then, based on the target blocks obtained by screening, further acquiring time stamps formed during the block creation, and forming a time correlation path of the target report information according to the time stamps. Finally, based on the time correlation path, the report information in the target block is extracted and sorted according to the time dimension, and finally, the sorted target report information can be accurately reflected in a set time interval, and the change condition of data in the target report information can be accurately reflected.
