Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The blockchain network is a network formed by a peer-to-peer network (P2P network) and a blockchain, and may include a plurality of node devices (nodes for short) inside; by node is meant a computer device in a blockchain network that performs data processing, which may include, but is not limited to: the system comprises terminal equipment such as an intelligent terminal, a tablet computer, a desktop computer and the like, an APP (application) running in the terminal equipment, service equipment (such as a data server and a cloud server) and the like. Each node stores an identical blockchain inside, and the blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission (P2P transmission), consensus mechanism, encryption algorithm and the like, and is essentially a decentralized database.

Referring to fig. 1a, a block chain may be composed of a plurality of blocks; the tile herein refers to a data structure for recording input information (e.g., transaction data), and the transaction data refers to any data that needs to be uploaded to the blockchain network, and does not refer to commercialized data. The starting block (i.e. the first block) includes a block header and a block body, the block header stores a hash value, a random number, a version number, a current timestamp and a current difficulty value of input information, and the block body stores input information of the starting block. The next block of the starting block takes the starting block as a parent block, and the next block also comprises a block head and a block main body; the block head stores the hash value of the input information of the current block, the hash value of the parent block, the random number, the version number, the current timestamp and the current difficulty value, and the block body stores the input information of the current block. By analogy, the block data stored in each block in the block chain is associated with the block data stored in the parent block, so that the safety of the input information in the block can be effectively ensured. The version number refers to version information of a related block protocol in a block chain; the parent block hash value refers to the hash value of the block head of the last block; the current timestamp refers to the system time when the block header is composed; the current difficulty value refers to a calculated difficulty value that is constant over a fixed time period and is determined again after the fixed time period is exceeded.

An embodiment of the present invention provides a data processing system based on a block chain network, as shown in fig. 1 b. In particular, the data processing system may include at least a blockchain network 11 and clients 12 located outside of the blockchain network. The blockchain network 11 may include: self-construction node 111, ticket node 112, and consensus node 113. The self-building node 111 is a node which is created in the blockchain network by a consuming user and has registered the bill service in the bill node; the bill node 112 is a node corresponding to a bill management organization in a block chain network, and can be responsible for checking the validity of a bill; the consensus node 113 refers to a node that can participate in consensus in the blockchain network, and the number of the consensus nodes 113 may be one or more. The client 12 may be configured to perform human-computer interaction with a consuming user, and send consumption information or a related request of the consuming user to the self-established node 111 in the blockchain network 11; the client 12 may specifically include any of: terminal equipment such as an intelligent terminal, a tablet computer or a desktop computer, or an APP running in the terminal equipment, and the like. It should be noted that fig. 1b is only an exemplary illustration of the system architecture of the data processing system according to the embodiment of the present invention, and does not limit the specific architecture of the data processing system. For example, in FIG. 1b, self-construction node 111 communicates with Ticket node 112; in practical applications, the self-established node 111 may also communicate with the consensus node 113. For another example, in addition to the self-establishing node 111, the billing node 112, and the consensus node 113, the blockchain network may further include other nodes (e.g., SPV (simple payment verification) node that only provides storage service), service nodes that provide service processing service, and so on.

Based on the data processing system, the embodiment of the invention also provides a data processing scheme to better realize the issuing of the target bill. The general principle of this data processing scheme is as follows: firstly, a consuming user can create a self-building node in a block chain network and authorize a user private key and a user certificate of the consuming user to the self-building node; and the self-built node can register the bill service with the bill node and deploy the own node certificate and the node private key in the bill node. When the consuming user wants to make a bill, the consuming information can be sent to the self-building node; the self-built node can construct a target bill according to the consumption information, and double signatures are carried out on the target bill by adopting a user private key of a consumption user and a node private key of the self-built node to obtain two pieces of signature information. Then, the self-building node can send the two pieces of signature information and the target bill to the bill node; correspondingly, the bill node can verify the legality of the target bill, and after the target bill passes the verification, the two pieces of signature information and the target bill are sent to the consensus node for consensus, so that the consensus node performs consensus on the target bill, and after the consensus passes the two pieces of signature information and the target bill are added to the block chain for storage.

Therefore, the embodiment of the invention provides the bill service for the consuming user through the self-built node created by the consuming user in the blockchain network; professional invoices are not needed to participate, and the invoicing efficiency can be effectively improved and the labor cost is reduced. In addition, in the billing process, the self-established node can acquire two signature information of the target bill by adopting a double signature mode, and stores the two signature information and the target bill in the block chain network together, so that the reliability and the safety of the target bill can be effectively improved.

Based on the above description, an embodiment of the present invention provides a data processing method based on a block chain network. Referring to fig. 2, the data processing method may include the following steps S201 to S206:

s201, the self-built node receives consumption information sent by a consumption user and constructs a target bill according to the consumption information.

In the embodiment of the present invention, the consuming user may refer to an independent user or a user organization (e.g. an enterprise) including a plurality of users. As can be seen from the foregoing, a self-established node is a node that is created by a consuming user in a blockchain network and is capable of performing invoicing actions based on ticketing services; therefore, when a consuming user wants to make a bill according to the consumption information, the consumption information can be sent to the self-construction node through the client, and the self-construction node constructs the target bill according to the consumption information. Correspondingly, the self-building node can receive consumption information sent by a consumption user through the client and construct a target bill according to the consumption information.

S202, the self-built node signs the target bill by adopting a user private key of a consuming user to obtain first signature information; and signing the target bill by adopting a node private key of the self-built node to obtain second signature information.

And S203, generating target transaction data by the self-built node according to the first signature information, the second signature information and the target bill.

In steps S202-S203, after the self-built node constructs the target ticket, the user private key of the consuming user and the node private key of the self-built node may be obtained from the storage space. The private key of the user of the consumption user is sent to the self-construction node when the consumption user authorizes the self-construction node in advance, and the private key of the node of the self-construction node is generated by the self-construction node in advance by adopting a key algorithm. Secondly, the self-built node can respectively adopt a user private key of a consuming user to sign the target bill to obtain first signature information; and signing the target bill by adopting a node private key of the self-built node to obtain second signature information. After the two pieces of signature information are obtained, the self-built node can package the first signature information, the second signature information and the target bill to obtain target transaction data.

It should be understood that, in the embodiment of the present invention, the order of the two signature steps mentioned in step S202 is not limited; the self-built node can concurrently adopt the user private key and the node private key to sign the target bill respectively, and simultaneously obtain first signature information and second signature information; or the self-built node can also adopt a user private key to sign the target bill to obtain first signature information, and then adopts a node private key to sign the target bill to obtain second signature information; or the self-built node can also adopt the node private key to sign the target bill to obtain second signature information, and then adopts the user private key to sign the target bill to obtain first signature information.

And S204, the self-built node sends the target transaction data to the billing node.

After the self-built node obtains the target transaction data, the target transaction data can be sent to the bill node, so that the bill node verifies the legality of the target transaction data, and the target transaction data are broadcasted to the consensus node after the target transaction data are verified; and after the target transaction data passes the consensus, submitting the target transaction data to a block chain of the block chain network.

Accordingly, the Ticket node may receive the target transaction data sent from the construction node and perform the following steps S205-S206. The target transaction data is generated by the self-establishing node according to the first signature information, the second signature information and the target bill; the target ticket is constructed based on consumption information sent by the consuming user. And the first signature information is obtained by signing the target bill by using a user private key of a consuming user, and the second signature information is obtained by signing the target bill by using a node private key of the self-built node.

S205, the bill node verifies the legality of the target transaction data.

In a specific implementation, the note node may first detect whether a target note in the target transaction data is legal; and if the target bill is illegal, determining that the target transaction data does not pass the validity verification. And if the target bill is legal, verifying the first signature information by adopting a user certificate of the consuming user, and verifying the second signature information by adopting a node certificate of the self-established node. If the verification is successful, determining that the target transaction data passes the validity verification; and if the verification fails, or one signature information in the first signature information and the second signature information fails, determining that the target transaction data fails in validity verification.

The specific implementation manner of the ticket node detecting whether the target ticket in the target transaction data is legal may be: detecting whether a target bill in the target transaction data contains a bill supervision stamp issued by the bill node; if the target bill contains the bill check stamp, the target bill is determined to be legal; otherwise, the target bill is determined to be illegal. In one embodiment, the target ticket includes a user name (e.g., a business name) corresponding to the consuming user and a taxpayer identification number; then, upon determining that the target ticket contains a ticket escrow stamp, the ticket node may further detect whether a taxpayer identification number exists in the target ticket. If the taxpayer identification number exists, detecting whether the user name corresponding to the taxpayer identification number is the same as the user name in the target bill or not; and if the target bill is the same, determining that the target bill is legal. And if the taxpayer identification number does not exist, or the user name corresponding to the taxpayer identification number is different from the user name in the target bill, determining that the target bill is illegal. In one embodiment, the target instrument includes a consumption type (such as diet, transportation), a unit of measurement, a consumption amount, a consumption unit price, a consumption amount, a tax rate, and a tax amount; then, after determining that the target ticket contains the ticket escrow stamp, the ticket node may further calculate the total amount according to the calculation units, the consumption amount, and the consumption unit price in the target ticket. If the calculated total amount is the same as the consumption amount in the target bill, the applicable tax rate can be determined according to the consumption type in the target bill. If the applicable tax rate is the same as the tax rate in the target bill, calculating the tax payment according to the consumption amount and the tax rate; and if the calculated tax payment is the same as the tax amount in the target bill, determining that the target bill is legal. Otherwise, the target ticket may be determined to be illegal.

And S206, if the target transaction data passes the validity verification, the bill node broadcasts the target transaction data to the consensus node.

If the target transaction data passes the validity verification, the bill node can broadcast the target transaction data to the consensus node, so that the consensus node performs consensus on the target transaction data, and submits the target transaction data to a block chain of the block chain network after the target transaction data passes the consensus.

Fig. 3 is a schematic flow chart of another data processing method based on a blockchain network according to an embodiment of the present invention. Referring to fig. 3, the data processing method may include the following steps S301 to S313:

s301, the self-built node responds to the node building instruction of the consuming user to acquire the equipment information of the self-built node.

In a specific implementation, if a consuming user wants to create a self-created node in a blockchain network, one device can be selected as the self-created node, and a node creation instruction is sent to the self-created node; the node creation instruction is used for indicating a self-created node to join the blockchain network and registering a bill service to a bill node in the blockchain network. Accordingly, the self-established node may receive a node establishment instruction sent by a consuming user. The bill node usually has a certain requirement on the encryption performance of the node to which the bill service is to be registered, so that the safety of the bill is ensured. Therefore, the self-construction node can respond to the node construction instruction and acquire the equipment information of the self-construction node; and generating a node creation request carrying the equipment information through steps S302-S303, and sending the node creation request to the bill node, so that the bill node can evaluate the encryption performance of the self-created node according to the equipment information. The device information of the self-established node comprises: the equipment identification of the self-built node and the hardware module information of the self-built node; the hardware module information can be used for reflecting the hardware module included in the self-building node.

And S302, the self-built node generates a node creation request carrying equipment information, wherein the node creation request is used for indicating that the self-built node is to be added into the block chain network and is to open a bill service.

And S303, the self-building node sends the node building request to the bill node.

After generating the node creation request, the self-created node may send the node creation request to the ticket node to request the ticket node to check whether the self-created node is qualified for service according to the device information, and broadcast the node creation request to the consensus node after determining that the self-created node is qualified for service. Accordingly, the ticket node may receive a node creation request sent from the creation node. As can be seen from the foregoing, the node creation request is generated by the self-created node in response to the node creation instruction of the consuming user, acquiring the device information of the self-created node, and according to the device information. The Ticket node may then perform steps S304-306.

S304, the bill node verifies whether the self-built node has service qualification according to the equipment information.

In one embodiment, the ticket node may determine whether one or more of the cryptographic engine and the cryptographic chip are included in the self-established node based on the device information. Wherein, the cipher machine is a device under the action of a secret key; the encryption chip is a security chip which integrates various symmetric and asymmetric algorithms inside, has extremely high security level and can ensure that keys and information data stored inside cannot be illegally read and tampered. If the self-built node comprises one or more of a cipher machine and an encryption chip, the encryption performance of the self-built node can be determined to be better; at this point, the ticketing node may determine that the self-created node qualifies for service. If the self-built node does not contain at least one of the cipher machine and the encryption chip, the encryption performance of the self-built node can be determined to be poor; at this point, the ticker node may determine that the self-created node is not eligible for service.

In one embodiment, if the self-building node comprises an encryption chip, the bill node can further detect the security level of the encryption chip; if the security level of the encryption chip is greater than a preset level, determining that the self-established node has service qualification; otherwise, it may be determined that the self-established node is not eligible for service. Similarly, if the self-built node comprises a cipher machine, the bill node can further detect the security level of the cipher machine; if the security level of the cipher machine is greater than the preset level, determining that the self-established node has service qualification; otherwise, it may be determined that the self-established node is not eligible for service.

S305, if the self-establishment node is determined to have the service qualification, the bill node broadcasts the node establishment request to the consensus node.

After the self-establishment node is determined to have the service qualification by the bill node, the bill node can broadcast the node establishment request to the consensus node, so that the consensus node performs consensus on the node establishment request, and returns an agreement establishment notification to the bill node after the node establishment request passes the consensus. It should be noted that, if the ticket node determines that the self-established node does not have the service qualification, the ticket node may directly return a creation rejection notification to the self-established node, and end the process.

Correspondingly, the consensus node can receive the node creation request sent by the ticket node and perform consensus on the node creation request based on a consensus mechanism. Specifically, each consensus node in the block chain network can vote for the node creation request to obtain a voting result of each consensus node; the voting result here may include a support voting result indicating that the node creation request is supported by consensus or a pair voting result against which the node creation request is opposed to consensus. If the number of the voting support results meets a preset condition, determining that the node creation request passes consensus; in this case, the consensus node may return an agreement creation notification to the Ticket node. Wherein the preset condition may include any one of: the number of supported voting results is greater than the number of anti-voting results, the number of supported voting results is greater than a number threshold, and so on.

S306, if the creation approval notice is received, the bill node opens the bill service for the self-created node, and a creation success notice is returned to the self-created node.

S307, if receiving the successful creation notification returned by the bill node, the self-created node joins the block chain network and starts the bill service.

And if a successful creation notice returned by the bill node is received, indicating that the consensus node and the bill node in the block chain network agree that the self-created node is added into the block chain network, and the bill node opens a bill service for the self-created node. Therefore, at this time, the self-established node can join the blockchain network (as shown in fig. 4) and open the billing service. The successful creation notice is sent by the self-establishing node after the self-establishing node opens the bill service and responds to the creation approval notice sent by the consensus node.

In one embodiment, if a creation success notification returned by the ticket node is received, the self-created node may send an authorization prompt to the consuming user to prompt the consuming user to perform identity authorization on the self-created node. Specifically, the self-building node may send an authorization prompt to a client of the consuming user, so that the client may output the authorization prompt in a user interface. After seeing the authorization prompt on the user interface, the consuming user can input corresponding identity authorization information on the user interface and instruct the client to send the identity authorization information to the self-building node. Correspondingly, the self-building node can receive the identity authorization information sent by the consuming user and store the identity authorization information of the consuming user. Wherein, the identity authorization information comprises: a user private key of the consuming user, and a user certificate of the consuming user; and the identity authorization information can be used for authorizing the self-built node to carry out signature by adopting a user private key. It should be noted that, after seeing the authorization prompt, the consuming user can directly input the identity authorization information on the user interface, thereby completing the authorization operation; in this case, a schematic flow chart of identity authorization can be seen in fig. 5 a. Or after seeing the authorization prompt, the consumer can firstly carry out identity authentication in the bill node; if the identity authentication is successfully carried out in the bill node, identity authorization information can be input in a user interface, so that the authorization operation is completed; in this case, the identity authorization information is sent by the consuming user after the authentication at the ticket node is successful, and a corresponding flow diagram of identity authorization can be seen in fig. 5 b.

In one embodiment, if a creation success notification returned by the ticket node is received, the self-created node may further obtain a node certificate of the self-created node and a node private key of the self-created node. Specifically, the self-established node may generate a key pair by using a key algorithm, and a private key in the key pair is used as a node private key of the self-established node; sending a certificate issuing request carrying a public key in the key pair to a certificate issuing authority to request the certificate issuing authority to issue a node certificate for the self-established node; then, the node certificate returned by the certificate issuing authority can be received. After the node certificate and the node private key are obtained, the self-built node can generate an identity registration request according to the node certificate and the node private key; and sending the identity registration request to the bill node to request the bill node to register and backup the node certificate and the node private key of the self-built node, so that the node certificate and the node private key can be obtained again from the bill node after the node certificate and the node private key are lost by the subsequent self-built node. Accordingly, the note node can receive an identity registration request sent by the self-construction node, wherein the identity registration request is generated by the self-construction node according to a node certificate of the self-construction node and a node private key. Then, the bill node can register the node certificate and the node private key of the self-built node and back up the node certificate and the node private key; and returning a registration success notice to the self-construction node. And if the self-building node receives the registration success notification returned by the bill node, the self-building node can determine that the identity registration is completed.

In one embodiment, if the self-built node detects that the node certificate and the node private key are lost, the self-built node may send a data acquisition request to the ticket node to request the ticket node to return the node certificate and the node private key. Correspondingly, if the bill node receives a data acquisition request sent by the self-built node, the backed-up node certificate and the node private key can be acquired; the data acquisition request is sent by the self-construction node after detecting that the node certificate and the node private key are lost. Then, the bill node can return the node certificate and the node private key to the self-established node; correspondingly, the self-built node can receive the node certificate and the node private key returned by the bill node.

S308, the self-built node receives the consumption information sent by the consumption user and constructs a target bill according to the consumption information.

S309, the self-built node signs the target bill by adopting a user private key of the consuming user to obtain first signature information; and signing the target bill by adopting a node private key of the self-built node to obtain second signature information.

And S310, generating target transaction data by the self-built node according to the first signature information, the second signature information and the target bill.

S311, the self-built node sends the target transaction data to the billing node.

In one embodiment, after obtaining the target transaction data, the self-construction node may directly send the target transaction data to the billing node. In still another embodiment, as can be seen from the foregoing, the self-established node may include a communication chip and an encryption chip. The communication chip and the bill node are in first communication connection; the encryption chip comprises a root key of the self-building node, and the encryption chip and the bill node are kept in second communication connection. In this embodiment, the self-established node may obtain the root key of the self-established node from the encryption chip, and generate a random number by using a random algorithm; the root key here refers to the key from which the other keys are derived. Secondly, the self-building node can generate a temporary key according to the root key and the random number, and encrypt target transaction data by adopting the temporary key; the temporary key is a key valid only for this encryption process, and the temporary key generated each time is different. The self-established node may then send the encrypted target transaction data to the ticker node based on the first communication connection and send the temporary key to the ticker node based on the second communication connection, such that the ticker node decrypts the encrypted target transaction data with the temporary key, as shown in fig. 6. Therefore, the double protection of the target transaction data can be realized by adopting the embodiment: the first protection is to encrypt by using a temporary key, and the other protection is to separately transmit encrypted target transaction data and the temporary key by using two communication connections; through a double protection mechanism, the safety of target transaction data can be effectively improved.

Accordingly, the Ticket node may receive the target transaction data sent from the SetNode and perform steps S312-S313. In one embodiment, if the self-established node is the target transaction data sent directly to the ticketing node, the ticketing node can directly receive the target transaction data sent from the self-established node. In an embodiment, if the self-established node sends the encrypted target transaction data to the ticketing node, the specific implementation manner that the ticketing node receives the target transaction data sent by the self-established node may be: the bill node can receive encrypted target transaction data sent by the self-construction node based on the first communication connection; the encrypted target transaction data is obtained by encrypting the target transaction data by the self-established node by adopting a temporary key, and the temporary key is generated according to a root key and a random number generated by adopting a random algorithm. And, the ticket node may also receive the temporary key sent from the originating node based on the second communication connection. Then, the billing node can decrypt the encrypted target transaction data by using the temporary key to obtain the target transaction data.

It should be understood that if the self-establishing node needs to send the temporary key to the ticket node, the self-establishing node may also establish a second communication connection with the ticket node before sending the temporary key. Specifically, the self-established node may first obtain a communication address of the encryption chip; and then the communication address of the encryption chip is sent to the bill node, so that the bill node establishes a second communication connection based on the communication address and the encryption chip. Correspondingly, the bill node can receive the communication address of the encryption chip sent by the self-construction node; and establishing a second communication connection based on the communication address and the encryption chip.

S312, the bill node verifies the legality of the target transaction data.

And S313, if the target transaction data passes the validity verification, the billing node broadcasts the target transaction data to the consensus node.

If the target transaction data passes the validity verification, the billing node may broadcast the target transaction data to the consensus node. Correspondingly, the consensus node can perform consensus on the target transaction data; it should be noted that the principle of consensus on the target transaction data is similar to the aforementioned principle of consensus on the node creation request, and is not described herein again. After the target transaction data passes the consensus, the consensus node may submit the target transaction data into a blockchain of the blockchain network. Specifically, if the target transaction data passes the consensus, the consensus node may pack the target transaction data into the target block. The specific process of packaging the transaction data into the target block is as follows: the consensus node may add the transaction data to the tile body of the target tile, as shown in FIG. 7 a. Secondly, the consensus node can perform hash operation on the target transaction data in the block main body by adopting a merkel Tree algorithm (Merkle Tree algorithm) to obtain a hash value of the target transaction data. Then, the consensus node may generate a random number by using a random algorithm, and form a block header of the target block by using the hash value of the target transaction data, the random number, the version number, the parent block hash value, the current timestamp, and the current difficulty value obtained by calculation. Performing multiple hash operations on the content contained in the head of the block by using a characteristic value algorithm (such as SHA256 algorithm) to obtain a hash value of the head of the block of the target block; the number of hash operations can be determined according to the calculation difficulty, and the larger the calculation difficulty is, the more the number of hash operations is. If the hash value of the block head of the target block is smaller than the preset threshold, the block head of the target block is valid, and then the valid target block can be obtained. If the characteristic value of the block head of the target block is not less than the preset threshold value, indicating that the block head of the target block is invalid; at this time, it is necessary to jump to the step of "generating a random number using a random algorithm" until a valid block header is generated. After the target block is obtained, the consensus node may add the target block to the blockchain of the blockchain network, as shown in fig. 7 b.
