The Block Chain (Block Chain) is a Chain data structure which combines data blocks in a sequential connection mode according to a time sequence and is a distributed book which is cryptographically used for ensuring that the data cannot be tampered and forged. Multiple independent distributed nodes (i.e., first block link point devices) maintain the same record. The blockchain technology realizes decentralization and becomes a foundation for credible digital asset storage, transfer and transaction.

Platform protocol data or activity announcement data is recorded in each block, and the hash (hash) value of the previous block is included, and all blocks store the hash value of the previous block in such a way and are connected in sequence to form a block chain. The hash value of the previous block is stored in the block head of the next block in the block chain, and when the fingerprint data in the current block changes, the hash value of the block is changed, so that the fingerprint data uploaded to the block chain network is difficult to tamper, the transaction between the client and the service platform is carried out on the block chain, the open and transparent transaction process is realized, and the reliability of the fingerprint data is improved.

Referring to fig. 3 based on the schematic architecture diagram of the data processing system of fig. 2, fig. 3 is a schematic flow chart of a data processing method provided in an embodiment of the present application, where a user platform in the method may be an e-commerce platform, an insurance platform, a payment platform, and the like, and the method includes, but is not limited to, the following steps S301 to S305:
s301, a first block chain node device receives first fingerprint data sent by a user platform, wherein the first fingerprint data comprises summary hash of at least one of platform protocol data and activity announcement data of the user platform.
Wherein the platform protocol or activity bulletin comprises any platform protocol or activity bulletin generated and published by the user platform, or all platform protocol or activity announcements generated and published by the customer platform, when the first blockchain node device receives the first fingerprint data from the customer platform, the first fingerprint data can be subjected to block chain chaining processing according to a user request, the user can be an enterprise user or a personal user, both the enterprise user and the personal user can send a request for performing the block chain chaining processing on the first fingerprint data to first block chain node equipment through a user platform, the user platform is associated with a user terminal, the user terminal comprises a mobile phone client, a computer client and the like, the user logs in the user platform after inputting account information of the user platform through the held terminal, and the terminal can become a terminal associated with the user platform. The first fingerprint data includes a digest hash of user platform protocol data or activity announcement data. The first cell link point device may be any node device in a cell chain associated with the user platform, for example, the cell link point device closest to the user terminal associated with the user platform, or the cell chain node device with the best communication quality with the user terminal.
In one implementation, before the first block link point device receives the first fingerprint data sent by the user platform, the method further includes: obtaining a storage certificate request sent by at least one user through the user platform, wherein the user comprises an enterprise user or an individual user; and after the certificate storing request is received, sending a data instruction to the user platform, wherein the data instruction is used for prompting the user platform to extract a data abstract of the platform protocol data or the activity announcement data, and performing digital signature on the data abstract to obtain first fingerprint data. After receiving a certificate storage request sent by at least one user terminal through a user platform, a first block chain network can verify the identity of the at least one user terminal, and sends a data instruction to the user platform after the verification is passed, wherein the data instruction prompts a user to process platform protocol data or activity announcement data by the user platform to obtain a data abstract of the platform protocol data or the activity announcement data, and carries out data signature on the data abstract, so that first fingerprint data is obtained, rather than directly sending the platform protocol data or the activity announcement data to first block chain link point equipment. When the user platform receives platform protocol data or activity announcement data submitted by a user, the user platform calculates the platform protocol data or the activity announcement data by adopting a preset Hash algorithm, and then obtains a Hash abstract of the platform protocol data or the activity announcement data, only the Hash abstract is needed to carry out uplink data, and at the moment, the first block chain node equipment can carry out uplink processing on the first fingerprint data after receiving the first fingerprint data.
In one implementation, the method further comprises: acquiring the platform protocol data or the activity announcement data in the first fingerprint data; and verifying whether the platform protocol data or the activity announcement data are publicly issued valid data. The first blockchain node equipment receives first fingerprint data, wherein the first fingerprint data comprises the abstract hash of platform protocol data or activity announcement data of a user platform, so that uplink processing is only needed to be carried out on the abstract hash, but before uplink processing, the first blockchain node equipment needs to acquire the platform protocol data or the activity announcement data firstly and verify whether the platform protocol data or the activity announcement data are valid data published publicly, if so, uplink processing is carried out on the first fingerprint data, and if not, no processing is carried out. For example, when the e-commerce platform issues a profit for rebate and rebate when a specific product is purchased in a certain time slot, the first fingerprint data is the activity announcement data, whether the activity announcement data is valid data which really exists needs to be detected, if yes, the platform already issues the activity announcement and the activity announcement is known by the user, and the user has purchased the specific product in the time slot, and in order to prevent the data from being tampered, the user cannot obtain the rebate after the activity is finished, the data needs to be uplink processed.
S302, the first block chain node equipment performs uplink processing on the first fingerprint data.
In one implementation, the uplink processing the first fingerprint data includes: verifying the first fingerprint data; when the first fingerprint data is successfully verified, sending the first fingerprint data to each second block chain node point device in a block chain network, so that each second block chain node point device performs block chain consensus on the first fingerprint data; when the block chain consensus passes, storing the first fingerprint data into a consensus ledger of the block chain network. Before the first fingerprint data is subjected to uplink processing, the first block chain link point device verifies the first fingerprint data, for example, whether the first fingerprint data meets uplink conditions is detected, whether the font size meets rules, whether the format meets specifications and the like are detected, after the verification is successful, the first block chain link point device sends the first fingerprint data to each second block chain link point device in a block chain network, at the moment, each second block chain link point device in the block chain network can perform block chain consensus on the first fingerprint data, when the block chain consensus passes, the first block chain link point device stores the first fingerprint data into a consensus book of the block chain network, and the verified and consensus first fingerprint data are stored in the block chain network and are not easy to be tampered and lost.
In one implementation, after storing the first fingerprint data in a consensus ledger of the blockchain network, the method further comprises: acquiring address information and transaction information of the first fingerprint data stored in the consensus ledger; and sending the address information and the hash of the transaction information to the user platform. The first block chain node can acquire address information and transaction information of the first fingerprint data stored in the common account book, and accordingly, the Hash of the address information and the transaction information is sent to the user platform, so that the user platform can acquire the first fingerprint data according to the address information and the transaction information and through other block chain node devices.
S303, after the first block link node device receives a fairness notification sent by the first server, the fairness notification includes the first fingerprint data and a first fairness certificate of the first fingerprint data.
The public and positive mechanism can acquire first fingerprint data from the block chain, and carry out public and positive on the first fingerprint data, carry out chain winding processing on the first fingerprint data and the first public and positive certificate after obtaining the first public and positive certificate, and the public and positive mechanism can realize chain winding processing on the first fingerprint data and the first public and positive certificate through the first block chain link point equipment, and can send a public and positive notice to the first block chain link point equipment at the moment, wherein the public and positive notice comprises the first fingerprint data and the first public and positive certificate.
S304, the first block chain node equipment carries out uplink processing on the first fairness certificate.
In specific implementation, after receiving a fairness notification, a first block link node device performs uplink processing on a first fairness certificate in the fairness notification, where the fairness notification includes first fingerprint data, and the first node device may first obtain address information of the first fingerprint data in a block link network, then store the first fairness certificate in an address that is the same as or close to the first fingerprint data, and establish a corresponding relationship between the first fingerprint data and the first fairness certificate.
In one implementation, the first certificate of fairness includes the first fingerprint data identifier and time information of the first fingerprint data, where the time information is used to indicate that the first fingerprint data exists before a time corresponding to the time information, and the first fingerprint data identifier is used to mark platform protocol data or activity announcement data associated with the first fingerprint data, or to mark platform protocol data and activity announcement data associated with the first fingerprint data. The first certificate of justice includes an identifier of the first fingerprint data and time information of the first fingerprint data, where the identifier may be an identifier uniquely used for identifying the first fingerprint data, such as key feature information of the first fingerprint data, address information stored in a blockchain network, and the like, and the time information may be, for example, a uplink time of the first fingerprint data, or an effective time or an issue time of a platform protocol or an activity announcement indicated by the first fingerprint data, and the time information is mainly used for proving that the first fingerprint data exists before a time corresponding to the time information, and the first fingerprint data is used for indicating accuracy of platform protocol data or activity announcement data associated with the first fingerprint data.
S305, when a first block chain link point device receives a judgment request sent by a second server, the first fingerprint data and the first justice certificate are obtained from the block chain, and the first data fingerprint and the first justice certificate are sent to the judicial platform, so that the judicial platform obtains a reference result according to the first fingerprint data and the first justice certificate after obtaining the first fingerprint data and the first justice certificate through the second server.
In a specific implementation, the judicial platform may obtain the first fingerprint data and the first certificate of fairness through the second server, specifically, the second server may send a decision request to the first blockchain network device, and the second server obtains the first fingerprint data and the first certificate of fairness from the blockchain after receiving the decision request. The judicial platform can obtain a reference result by the first fingerprint data and the first justice certificate, and further carry out judicial judgment.
For example, in the application scenario that the user platform is an e-commerce platform and the first fingerprint data is summary hash of the shopping festival activity announcement data, the first target user purchases an item a after seeing the activity announcement issued by the e-commerce platform, the activity announcement indicates that the purchased item a can participate in a discount activity of buying one and sending one within a specified time period of a specified date, but the first target user, after receiving item a, finds that the e-commerce platform does not make any one-for-one promised in the activity bulletin, the first target user can initiate an arbitration request to the judicial platform for this situation, as long as the first target user stores the activity announcement issued by the e-commerce platform into the blockchain through the blockchain link point device associated with the e-commerce platform in advance, and the certificate is just performed by a just platform in advance, and the generated just certificate is stored in the block chain network. At this time, the first target user submits evidence data to the judicial platform, the judicial platform extracts evidence obtaining data from the block chain, and the corresponding shopping festival activity announcement data in the evidence obtaining data is compared with the shopping festival activity announcement data in the evidence data submitted by the first target user, so that the validity of the evidence data can be verified, and the rights and interests of the first target user are guaranteed.
For another example, in an application scenario where the user platform is an e-commerce platform and the first fingerprint data is summary hash of the shopping rebate agreement data, the second target user sees the shopping rebate agreement issued by the e-commerce platform, and purchases a specific commodity of the e-commerce platform in the shopping rebate agreement, so that the second target user can enjoy a rebate offer, and the rebate is 50% higher, so that the second target user purchases a commodity B. After the second target user purchases the commodity B and confirms to receive the commodity, and the e-commerce platform does not execute the shopping rebate protocol or the rebate proportion does not have 50% of the promise in the shopping rebate protocol, the second target user can make an arbitration request to the judicial platform, because the second target user stores the shopping rebate protocol data in an uplink manner through the block chain link point equipment associated with the e-commerce platform in advance and stores a justice certificate generated after justice by the justice platform in the block chain, when the user submits evidence data to the judicial platform, the judicial platform can obtain evidence for evidence collection from the block chain and compares the corresponding shopping rebate protocol data in the evidence collection data with the corresponding shopping rebate protocol data in the evidence data, so as to determine whether the evidence data submitted by the second target user is valid data, and finally obtain a judgment result, the method is beneficial to simultaneously guaranteeing the user rights and the platform rights.
