Detailed Description
The embodiment of the invention provides a data processing method, which can realize the credibility check of target bill data created by a first terminal for a second terminal by introducing a server with higher credibility, and only after the credibility check of the target bill data by the server is passed, the second terminal can obtain the target bill data, and based on the check of the server with higher credibility on the target bill data, the risk that the first terminal optionally offers the bill data for the second terminal can be effectively avoided, and the effective specification of the issuing behavior of the bill data is realized. In a specific implementation, the server checks the target bill data and determines that the target bill data passes the check, and then the server can directly send the target bill data to the second terminal, but in order to ensure that the check result of the server on the target bill data is not maliciously tampered, the server can also upload the target bill data to the blockchain network after determining that the target bill data passes the check, so that the blockchain network performs consensus processing on the target bill data after acquiring the target bill data, and after the blockchain network performs consensus on the target bill data, the second terminal can acquire the target bill data after the consensus is completed from the blockchain network.
In one embodiment, the blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. The Blockchain (Blockchain) is essentially a decentralized database, which is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer. The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the valid request after consensus is completed on storage, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, and transmits the encrypted service information to a shared account (network communication) completely and consistently, and records and stores the encrypted service information.
The target bill data can be effectively ensured to be generated based on real resource replacement between the first terminal and the second terminal based on the verification of the server on the target bill data, and the verification result of the server on the target bill data can be effectively ensured to be the bill data which is not tampered based on the consensus processing of the block chain network on the target bill data, so that the authenticity of the verification result of the target bill data is effectively ensured. In one embodiment, the data processing method may be applied to a data processing system as shown in fig. 1a, the data processing system includes a first terminal 10, a second terminal 11, and a server 12, after the first terminal 10 and the second terminal 11 perform resource replacement, if the resource replacement is that the second terminal 11 acquires a target item resource from the first terminal 10 by using a target amount of electronic resources, the first terminal 10 creates target ticket data for the second terminal 11, wherein after the target ticket data is generated by the first terminal 10, the target ticket data is first sent to the access 12, so that the server 12 performs a credibility check on the target ticket data. In one embodiment, the server 12 verifying the trustworthiness of the target ticket data includes: whether the target bill data is created under the condition that a real resource replacement operation is executed and/or whether a terminal (namely, the first terminal 10) creating the target bill data is a risk terminal with randomly issued bill data is verified, after the server 12 receives the target bill data sent by the first terminal 10 and completes the credibility verification of the received target bill data, the target bill data passing the credibility verification can be sent to the second terminal 11, so that the second terminal 11 can obtain the target bill data.
In one embodiment, in order to ensure that the target bill data generated by the first terminal, and the verification result of the server on the target bill data are not tampered, the first terminal, the second terminal, and the server may all be connected to a blockchain network, as shown in figure 1b, the first terminal 10, the second terminal 11 and the server 12 are all communicatively coupled via a blockchain network 13, which, as will be appreciated, the first terminal 10, the second terminal 11 and the server 12 may be node devices in a blockchain network 13, thereby enabling the first terminal 10, the second terminal 11 and the server 12 to establish a communication connection, or, the first terminal 10, the second terminal 11 and the server 12 may not be node devices in the blockchain network 13, but establishes a communication connection through the blockchain network 13 by making a connection with a node device in the blockchain network. For example, the first terminal 10, the second terminal 11 and the server 12 can access the blockchain network 13 through Simple Payment Verification (SPV) nodes in the blockchain network 13, as shown in fig. 1c, the first terminal 10 can establish a communication connection with one node device (e.g., SPV1) in the blockchain network, the second terminal 11 can establish a communication connection with another node device (e.g., SPV2) in the blockchain network, and the server 12 can establish a communication connection with another node device (e.g., SPV3) in the blockchain network, so that the first terminal 10, the second terminal 11 and the server 12 establish a communication connection through the blockchain network.
When the server 12 performs the reliability verification on the obtained target bill data, the server 12 may obtain a white list from the blockchain network, thereby determining that the second terminal is a trusted terminal by judging whether the terminal identifier of the second terminal that creates the target bill data is recorded in the white list, and when the terminal identifier of the second terminal is recorded in the white list, that is, a terminal that does not perform the purchase of the bill data without performing the resource replacement, and further the server 12 may consider that the target bill data passes the reliability verification; alternatively, if the server 12 determines that the terminal identifier of the second terminal is not in the white list, it may send a logistics record acquisition request to the logistics equipment through the blockchain network, to obtain the logistics record between the first terminal and the second terminal from the logistics apparatus, and/or the server 12 may also send an obtaining request to a recording apparatus for recording the transfer of electronic resources between the first terminal and the second terminal, to obtain the resource transfer record between the first terminal and the second terminal from the recording device (i.e. the sending record of the electronic resource sent by the second terminal to the first terminal), further, the server 12 may determine whether the resource replacement operation is actually performed based on the logistics record and/or the electronic resource transfer record, and upon determining that the resource replacement operation is actually performed, determining that the target ticket data passes the trustworthiness check.
In one embodiment, if the server determines that the target ticket data does not pass the reliability verification, the server may directly discard the target ticket data to prevent the second terminal from acquiring the target ticket data, and when the server determines that the target ticket data does not pass the reliability verification, the server may perform invalidation processing on the target ticket data to prevent the first terminal from performing a ticket fraud based on the generated target ticket data. For example, the target bill data may be a value-added tax special invoice, after the first terminal and the second terminal perform target item replacement, the first terminal generates the value-added tax special invoice and sends the value-added tax special invoice to a server corresponding to a tax bureau, the server may verify the value-added tax special invoice to determine whether the value-added tax special invoice is generated under the condition that the target item replacement is really performed between the first terminal and the second terminal, and when the server corresponding to the tax bureau determines that the value-added tax special invoice is generated under the condition that the target item replacement is really performed between the first terminal and the second terminal, the value-added tax special invoice may be forwarded to the second terminal so that the first terminal and the second terminal may be used in subsequent tax reporting, and the verification of the target bill data generated between the first terminal and the second terminal based on the server may effectively avoid the first terminal and the second terminal from performing bill data issuing based on false resource replacement behavior privately The method and the device ensure the authenticity of the issued bill data, and can effectively avoid the tax evasion behaviors of the first terminal and the second terminal when the bill data is related to the tax.
Referring to fig. 2, a schematic flow chart of a data processing method according to an embodiment of the present invention is shown in fig. 2, where the method includes:
s201, acquiring target bill data, wherein the target bill data is created for the second terminal by the first terminal after resource replacement is executed between the first terminal and the second terminal.
In one embodiment, the resource permutation between the first terminal and the second terminal comprises: the second terminal acquires the target article resource from the first terminal by adopting the target quantity of electronic resources, namely, the resource replacement behavior comprises a transaction behavior, when the resource replacement behavior is the transaction behavior, the first terminal is the terminal device corresponding to the seller in the transaction, and the second terminal is the terminal device corresponding to the buyer in the transaction. It can be understood that if the first terminal acquires the article resource from the second terminal by using a certain amount of electronic resources, the second terminal creates the ticket data for the first terminal, and after the second terminal creates the ticket data for the first terminal, the second terminal can also send the ticket data created for the first terminal into the blockchain network after passing the credibility check on the ticket data created for the first terminal, so that the first terminal acquires the ticket data created for the second terminal from the blockchain network.
In one embodiment, the target bill data created by the first terminal for the second terminal may be used as a receipt for confirming, by the first terminal, that the target amount of the electronic resource sent by the second terminal is received, and when the resource replacement action is a transaction action, the target bill data may be, for example, a receipt or an invoice that the first terminal receives the target amount of the electronic resource from the second terminal, and further specifically, the invoice created by the first terminal for the second terminal may be a general value-added tax invoice or a special value-added tax invoice, and the like, where the general value-added tax invoice may be used as a reimbursement certificate, and the special value-added tax invoice may be used as an in-out certificate for the first terminal and the second terminal, and is used for deduction of taxes. Based on various different functions of the target ticket data, if the target ticket data created by the first terminal for the second terminal has no reliability, that is, if the target ticket data created by the first terminal for the second terminal based on the false resource replacement exists, the reliability of the amount of electronic resources in the first terminal and/or the second terminal determined based on the target ticket data will be low, and therefore, in order to ensure the reliability of the amount of electronic resources in the first terminal and the second terminal, it is necessary to ensure that the target ticket data created by the first terminal for the second terminal needs to have a certain reliability, so after the target ticket data is created for the second terminal by the first terminal, the created target ticket data needs to be checked for reliability (or reliability check), that is, step S202 is executed.
In one embodiment, the false resource replacement includes one or more of the following: the second terminal acquires the target article resource from the first terminal, but the second terminal does not transfer the target quantity of electronic resources to the first terminal; or the first terminal acquires the target quantity of electronic resources from the second terminal, but does not send the target article resources to the second terminal; or the first terminal does not acquire the target quantity of electronic resources sent by the second terminal, and the second terminal also receives the target article resources. In one embodiment, the electronic resource includes digital currency, virtual currency, or electronic currency, among others.
S202, obtaining verification information of the target bill data, and verifying the credibility of the target bill data by adopting the verification information.
In a specific implementation, after the server acquires the target bill data created by the first terminal for the second terminal, the server may further acquire verification information of the target bill data to perform credibility verification on the target bill data based on the verification information in order to ensure that the target bill data is generated based on real resource replacement performed between the first terminal and the second terminal. In one embodiment, the server checks the target ticket data includes checking the trustworthiness of a first terminal that creates the target ticket data, and in order to check the trustworthiness of the first terminal, the server may determine whether the first terminal is a trusted terminal, and when determining that the first terminal is a trusted terminal, determine that the target ticket data created by the first terminal passes the trustworthiness check, where it is understood that a white list is used to record a trusted identifier, and then the server may determine whether the second terminal is a trusted terminal by determining whether a terminal identifier of the second terminal is recorded in the white list. In an embodiment, the trusted terminal is a terminal that generates ticket data based on a false resource replacement with a low probability, or a terminal that has a long lifetime and cannot log out in a short period, for example, the second terminal may be a terminal device corresponding to a large enterprise, such as a terminal device corresponding to a large supermarket or a terminal device corresponding to a hospital.
In one embodiment, the server's verification of the target ticket data further includes a verification of the authenticity of the resource permutation performed, it being understood that the target ticket data generated based on the resource permutation may be determined to pass the trustworthiness verification when the server determines that the resource permutation performed is a true execution, and may be determined to fail the trustworthiness verification if the server determines that the resource permutation performed is a false execution. It is understood that, it is determined whether the resource replacement is actually performed, that is, it is determined whether the target amount of electronic resources related to the resource replacement and the corresponding target article resources actually perform the transfer, that is, the server, when determining whether the resource replacement is actually performed, may determine whether the target article resources are actually transferred through the logistics record, and determine whether the target amount of electronic resources are actually transferred between the first terminal and the second terminal through the transmission record of the electronic resources, so that it may be determined that the resource replacement is actually performed when the logistics record indicates that the target article is actually transferred, and the transmission record indicates that the target amount of electronic resources are actually transferred.
After the server determines that the resource replacement is a replacement that is actually performed, it may be determined that the target ticket data passes the reliability check, and then step S203 is performed, whereas if the server determines that the target ticket data does not pass the reliability check, the target ticket data may be directly discarded. In one embodiment, the server's trust check on the target ticket data may also check the first terminal's trust and the authenticity of the resource replacement performed at the same time.
And S203, if the target bill data passes the credibility verification, sending the target bill data to the block chain network so that the second terminal acquires the target bill data from the block chain network.
After the server determines that the target bill data passes the credibility verification, the target bill data can be sent to the blockchain network, so that the blockchain network performs consensus processing on the target bill data, and after the second terminal determines that the blockchain network completes consensus on the target bill data, the second terminal can obtain the target bill data with completed consensus from the blockchain network, so that the reliability of the target bill data sent to the second terminal is ensured, and the authenticity (or reliability) of the electronic resource amount in the first terminal and the second terminal determined based on the target bill data can be ensured. In one embodiment, the target bill data may be, for example, a special value-added tax invoice (or simply referred to as a special bill), the special bill can effectively avoid the problem of repeated tax collection, and can avoid the problem of tax evasion caused by making a special bill between enterprises, after making the special bill, the server needs to perform a reliability check on the made special bill before performing an actual tax deduction, wherein the reliability check on the special bill is performed based on a block chain network, so that the reliability and the validity of the check on the special bill can be ensured.
In one embodiment, the server may be a server used by a tax bureau to perform tax business, the first terminal may be a terminal device corresponding to enterprise a, and the second terminal may be a terminal device corresponding to enterprise B, if enterprise B is a purchasing enterprise and enterprise B sends a target amount of electronic resources to enterprise a to obtain target item resources, a process of generating target bill data based on a purchasing process between enterprise a and enterprise B may be as shown in fig. 3, and its specific process is as follows:
firstly, generating special tickets by the enterprise A based on the electronic resources with the target quantity;
the enterprise A sends the generated special ticket to a server;
thirdly, the server checks the credibility of the special ticket to determine whether the possibility of tax evasion exists in the enterprise A and the enterprise B;
if the server passes the credibility verification of the special ticket, forwarding the generated special ticket to the enterprise B;
and fifthly, after receiving the special ticket, when the tax is reported, the enterprise B uses the special ticket to deduct the tax.
In the embodiment of the invention, the server performs resource replacement between the first terminal and the second terminal, and the first terminal creates target bill data for the second terminal, can acquire the target bill data created by the first terminal, and performs credibility verification on the target bill data based on the verification information, further, the server can send the target bill data to the block chain network after the target bill data passes the credibility verification, so that the second terminal acquires the target bill data from the block chain network, thereby effectively avoiding the disorderly opening of bill data between the first terminal and the second terminal, effectively standardizing the opening behavior of bill data between different terminals, and further avoiding the economic loss of the server caused by the behavior of disorderly opening bill data between terminals, and in addition, based on the characteristic that data in the block chain network cannot be tampered, the authenticity of the target bill data acquired by the second terminal from the block chain network is ensured.
Please refer to fig. 4, which is a schematic flowchart of a data processing method according to an embodiment of the present invention, as shown in fig. 4, the method may include:
s401, acquiring target bill data, wherein the target bill data is created for a second terminal by a first terminal after resource replacement is executed between the first terminal and the second terminal; the target bill data is in a to-be-generated state.
In an embodiment, the specific implementation of step S401 may refer to the specific implementation of step S201 in the above embodiments, and is not described herein again.
S402, obtaining the verification information of the target bill data, and verifying the credibility of the target bill data by adopting the verification information.
In an embodiment, when the server performs the reliability check on the target ticket data, the acquired verification information includes a white list, where the white list is stored in the blockchain network, and then when the server acquires the white list, the server may acquire the white list from the blockchain network, specifically, the server may first send a first acquisition request for acquiring the white list to the blockchain network, so that after the blockchain network completes the consensus on the first acquisition request, the blockchain network sends the first acquisition request to the storage terminal of the white list, and acquires the white list from the storage terminal, and further, the server may acquire the consensus-completed white list from the blockchain network after the blockchain network completes the consensus on the acquired white list. In an embodiment, the white list is used to record a trusted identifier, that is, it can be understood that a terminal corresponding to the trusted identifier recorded by the white list is a trusted terminal, and then, when the server performs the trust level check on the target ticket data by using the white list, it may be checked whether the terminal identifier of the second terminal is the trusted identifier recorded in the white list; the second terminal may be determined to be a trusted terminal if the server determines that the terminal identity of the second terminal is listed in the white list.
In one embodiment, the server may also determine whether the target ticket data passes the credibility check by checking the authenticity of the resource replacement performed between the first terminal and the second terminal, wherein the server may determine the authenticity of the resource replacement performed between the first terminal and the second terminal through a replacement record when the first terminal and the second terminal perform the resource replacement, that is, the server may use the replacement record as the verification information, thereby checking the authenticity of the target ticket data. Similarly, the replacement record is recorded in the blockchain network, the server may obtain the replacement record from the blockchain network, and when the server obtains the replacement record and performs a reliability check on the target ticket data based on the replacement record, the server may determine, according to the replacement record, authenticity of resource replacement performed between the first terminal and the second terminal, and when the resource replacement that the server does perform is authentic, it may determine that the target ticket data passes the reliability check.
In one embodiment, the resource permutation performed between the first terminal and the second terminal comprises: the second terminal obtains the target asset from the first terminal using the target amount of electronic assets, and it is understood that the replacement record may comprise a logistics record. Then, when the server acquires the replacement record from the blockchain network, the server may first send a second acquisition request for acquiring the physical distribution record between the first terminal and the second terminal to the blockchain network, so that after the blockchain network completes the consensus on the second acquisition request, the blockchain network sends the second acquisition request to the physical distribution device, and acquires the physical distribution record indicated by the second acquisition request from the physical distribution device; after the block chain network completes the consensus on the logistics record acquired from the logistics equipment, the server can acquire the consensus-completed logistics record from the block chain network. The logistics record is used for recording logistics information of at least one article resource between the first terminal and the second terminal; the server, in determining whether the resource replacement performed between the first terminal and the second terminal is actually performed according to the logistics record, may determine that the resource replacement performed between the first terminal and the second terminal is actual if the server determines that the logistics record includes logistics information of the target item resource.
In an embodiment, the replacement record may further include a transmission record of the electronic resource sent by the second terminal to the first terminal, where the transmission record is also stored in the blockchain network, and then when the server acquires the transmission record from the blockchain network, the server may also first send a third acquisition request for the transmission record to the blockchain network, so that the blockchain network sends the third acquisition request to the recording device of the electronic resource after the consensus on the third acquisition request is completed, and acquires the transmission record indicated by the third acquisition request from the recording device; further, after the blockchain network completes the identification of the sending record obtained from the recording device, the server may obtain the sending record with completed identification from the blockchain network. It will be appreciated that the sending records include at least one record of the sending of the electronic resource by the second terminal to the first terminal; the server may first determine whether the transmission record includes a record for transmitting the target number of electronic resources when determining whether the resource replacement performed between the first terminal and the second terminal is actually performed according to the transmission record, and may determine that the resource replacement performed between the first terminal and the second terminal is actually performed if the server determines that the transmission record includes a record for transmitting the target number of electronic resources.
In one embodiment, the server may determine that the resource replacement performed between the first terminal and the second terminal is real based on only the logistics record included in the replacement record, or only the transmission record for the electronic resource included in the replacement record; alternatively, the server may also refer to the physical distribution record and the transmission record for the electronic resource at the same time, and may determine that the resource replacement performed between the first terminal and the second terminal is real.
