Detailed Description
The embodiments of the present application will be described below with reference to the drawings.
With the rapid development of science and technology, the human society gradually advances into the internet era, and the internet technology accelerates the information transmission, facilitates modern communication and reduces the world range. But the internet technology is also a double-edged sword, which brings convenience to people and brings hidden danger to people. Such as information leakage, spurious information propagation, etc.
Taking the bill false opening as an example, the bill false opening means that the invoicing party utilizes false identity information to issue a bill and then the issued bill is distributed to other companies or individuals so as to earn private interest. For example, the invoicing party illegally acquires the identity information of other people through the internet, registers the empty-shell company by using the identity information of other people, and after the empty-shell company is operated for a period of time, the invoicing is convenient to take out the invoice by using the empty-shell company, and then the invoice is distributed to other companies or people earn benefits. Therefore, in the process of issuing bills by the invoicers by means of false identity information, the bills are not associated with the invoicers, so that the information of the invoicers cannot be traced back according to the bills when problems occur in subsequent bills, and the national fund loss verification is caused.
In order to solve the above problems, embodiments of the present application provide a method for issuing a bill and a block link point device, where the method for issuing a bill and the block link point device are implemented based on a block chain technology.
The Block Chain (BC) is a novel application mode of computer technologies such as distributed data storage, consensus mechanism, encryption algorithm and the like. The block chain technology has the characteristics of decentralization, openness, independence, safety, anonymity and the like. Generally, a traditional transaction model is a transaction model constructed based on centralized thinking, that is, on the premise that two transaction parties do not trust each other, the centralized formation of a third party is promoted, and the third party serves as an arbitrator to witness the activities of the two transaction parties in the transaction process. The decentralized feature of the blockchain technology means that in a blockchain network, each node device stores data, data redundancy is realized through distributed storage, all nodes can have the ability to maintain the safety of a database, and the whole transaction is autonomous and simplified.
In the scenario of issuing a bill, the block chain technique is introduced, and the method for issuing a bill provided by the embodiment of the present application includes: the method comprises the steps that a first block chain node point device receives a bill making request sent by a second block chain node point device, wherein the bill making request comprises a digital certificate of the second block chain node point device; the first block chain link point device compares the digital certificate included in the bill making request with a digital certificate of a second block chain link point device stored in the first block chain link point device; if the digital certificate included in the bill issuing request is the same as the digital certificate stored in the first block chain node point device, the first block chain node point device responds to the bill issuing request to generate a bill and sends the bill to the second block chain node point device, so that the second block chain node point device signs the bill according to the private key of the second block chain node point device to obtain the digital signature of the bill, and the second block chain node point device issues the bill, the digital signature and the digital certificate of the second block chain node point device to the block chain network.
It should be noted that the first block link point device and the second block link point device belong to the same block chain network. In the scenario of the bill making, the first block chain node device may be a tax bureau, and the second block chain node device may be a client. The embodiment of the present application does not limit the first block link point device or the second block link point device in other scenarios.
Therefore, the first block chain link point equipment verifies the digital certificate in the bill issuing request, and the identity information of the issuing party can be ensured to be real and reliable. And the second block chain node point equipment receives the bill sent by the first block chain node point equipment, and signs and chains the bill according to the private key of the second block chain node point equipment. The method can establish the incidence relation between the bill and the invoicer, thereby ensuring that the tracing process of the subsequent bill is more reliable and reducing the false opening condition of the bill.
Referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a billing system according to an embodiment of the present application. As shown in fig. 1, the issuing ticket system includes: a first block link point device, at least one second block link point device. The first block chain link point device and each second block chain link point device form a block chain network, and all block chain node devices in the block chain network share information in the block chain. The first block chain node point device may be a tax bureau, and the second block chain node point device may be a client.
The second block link point device sends a ticket issuing request to the first block link point device, the ticket issuing request including a digital certificate of the second block link point device. The first block link point device compares the digital certificate included in the ticket issuing request with a digital certificate of a second block link point device stored by the first block link point device. And if the digital certificate included in the bill issuing request is the same as the digital certificate of the second block chain link point device stored in the first block chain link point device, the first block chain link point device responds to the bill issuing request to generate a bill and sends the bill to the second block chain link point device. Correspondingly, the second block chain node point equipment signs the bill according to the private key of the second block chain node point equipment to obtain a digital signature. The second blockchain link point device also issues the ticket, the digital signature, and the digital certificate to the blockchain network.
Based on the schematic architecture of the billing system shown in fig. 1, please refer to fig. 2, and fig. 2 is a schematic flow chart of a method for billing according to an embodiment of the present application, which includes, but is not limited to, the following steps:
step S201: the first block chain node device receives a bill making request sent by the second block chain node device.
Wherein the ticket issuing request includes a digital certificate for the second block link point device. Note that the ticket issuing request may include information of the biller in addition to the digital certificate of the second block link point device. Such as a business name, a business address, etc.
For example, the first block link point device is a tax bureau, and the second block link point device is company B, so when company B wants to issue a bill, it needs to send a bill issuing request to the tax bureau. The ticket issuing request should include a digital certificate of company B, the name of company B, the address of company B, the account number of company B, the bank of company B, the phone of company B, and so on.
Step S202: the first block link point device compares the digital certificate in the ticket issuing request with a digital certificate of a second block link point device stored by the first block link point device.
A digital Certificate is a relatively authoritative and fair Certificate issued by a Certificate Authority (CA), and is a digital Certificate that identifies user identity information in internet communications. The digital certificate encrypts or decrypts information and data of network users in computer network traffic, so that the integrity and the safety of the information and the data are ensured. Referring to fig. 3, fig. 3 is a schematic diagram of a digital certificate disclosed in an embodiment of the present application, and as shown in fig. 3, the digital certificate may include, but is not limited to: enterprise name, enterprise address, taxpayer identification number, account row, public key, hash, and the like.
In one implementation, a first block link point device compares a digital certificate in a ticket issuing request with a digital certificate of a second block link point device stored by the first block link point device. If the digital certificate in the ticket issuing request is the same as the digital certificate of the second block chain node device stored by the first block chain node device, the first block chain node device may determine that the identity of the party issuing the ticket issuing request sent by the second block chain node device is legitimate. That is, the first block link point device allows a biller that sent a ticket making request to make a ticket.
The digital certificate in the ticket issuing request is obtained by: and the first block link point equipment issues a digital certificate of the second block link point equipment and sends the digital certificate to the second block link point equipment. Thus, the digital certificate is included in the ticket issuing request sent by the biller to the first block-link point device by the second block-link point device.
It will be appreciated that the digital certificate stored by the first block-link point device does not include only the digital certificate of the second block-link point device. For example, if the first blockchain link point device successfully verifies the third blockchain node device in the blockchain network, the first blockchain link point device may further store the digital certificate of the third blockchain node device.
It can be known that the first block chain node point device verifies the digital certificate in the ticket issuing request, and if the verification passes, the first block chain node point device responds to the ticket issuing request. The identity of the invoicing party can be ensured to be credible, and further the false invoicing of the bill is avoided.
Step S203: and if the digital certificate in the bill issuing request is the same as the digital certificate of the second block chain link point device stored in the first block chain link point device, the first block chain link point device responds to the bill issuing request to generate a bill.
Specifically, the first block link point device generates a ticket according to a ticket issuing request. The request includes information of the invoicing party, such as the name of the business, the address of the business, and the like. A ticket is a security of value having a certain amount of money. The ticket may be a money order, a promissory note, a check, an invoice, and the like. Referring to fig. 4, fig. 4 is a schematic view of a ticket provided in an embodiment of the present application, and as shown in fig. 4, the ticket may include, but is not limited to: the name of the person to be billed, the taxpayer identification number of the person to be billed, the address of the person to be billed, the phone of the person to be billed, the line and account number of the person to be billed, transaction information, and tariff totals.
Step S204: the first block link point device sends the bill to the second block link point device.
Step S205: and the second block chain node equipment signs the bill according to the private key to obtain the digital signature of the bill.
Specifically, the second block chain node point device signs the bill according to a private key of the second block chain node point device to obtain a digital signature of the bill. That is, the association relationship between the ticket and the invoicer is established, so that the invoicer who makes the invoicer through the second block link point device can be found through the ticket.
Step S206: the second blockchain link point device issues the ticket, the digital signature and the digital certificate to a blockchain network.
Specifically, the second blockchain link point device issues the ticket, the digital signature, and the digital certificate to the blockchain network. Namely, the note, the digital signature and the digital certificate are linked. Accordingly, the first blockchain link point device in the blockchain network can acquire the bill, the digital signature and the digital certificate.
As can be seen, after the first block chain node point device successfully verifies the digital certificate in the ticket issuing request, the first block chain node point device generates a ticket and sends the ticket to the second block chain node point device. And the second block chain link point equipment signs the bill and chains the bill. The incidence relation can be established between the bill and the invoicer, the tracing process of the follow-up bill is ensured to be more reliable, and the condition of the virtual opening of the bill can be reduced
Referring to fig. 5, fig. 5 is a schematic flow chart of another method for issuing a ticket according to an embodiment of the present application, where the method may include:
step S501: the first block chain node equipment receives identity information and biological characteristic information sent by the second block chain node equipment.
The identity information includes the name, gender, telephone, etc. of the drawer. The biometric information includes fingerprint feature information, face feature information, iris feature information, or the like of the drawer.
Step S502: the first block link point device compares the identity information and the biometric information.
In one implementation, a method of a first tile link point device comparing identity information and biometric information may comprise: the first block chain node equipment searches biological characteristic information corresponding to the identity information; and the first block chain node point equipment compares the biological characteristic information sent by the second block chain node point equipment with the searched biological characteristic information. If the biometric information sent by the second block link point device is the same as the found biometric information, the first block link point device may determine that the identity information used by the drawer for drawing the invoice is true and valid, and then the first block link point device may perform the operation of step S503.
Specifically, the first block link point device may obtain biometric information corresponding to the identity information through other devices. For example, the first block link point device is a tax bureau, and then the tax bureau can obtain identity card information corresponding to the identity information through a public security bureau in communication with the tax bureau, where the identity card information includes facial feature information (biometric information) corresponding to the identity information, and the like.
Step S503: and if the biological characteristic information sent by the second block link point equipment is the same as the searched biological characteristic information, the first block link point equipment acquires the enterprise information.
Step S504: and the first block chain node equipment receives the enterprise information sent by the second block chain node equipment.
The enterprise information refers to information of an enterprise represented by the drawer, and the enterprise information may include but is not limited to: business name, business address, business taxpayer identification number, business account opening row and account, business phone, etc.
Step S505: and the first block link point equipment judges whether the enterprise corresponding to the enterprise information is a credit enterprise or not according to the enterprise information.
In one implementation, the implementation process of step S505 may include: the first block chain node equipment acquires registration information corresponding to the enterprise information from the management equipment according to the enterprise information; and the first block link point device judges whether the enterprise corresponding to the enterprise information is a credit enterprise or not according to the registration information. Optionally, the management device may also be a block link point device. The management device is used for storing the registration information of the enterprise.
For example, the first block link point device is a tax bureau, the management device is a business bureau, the business bureau stores registration information of at least one enterprise, and the tax bureau and the business bureau can mutually acquire information. After the tax bureau obtains the enterprise information of the enterprise, the tax bureau can obtain the registration information of the enterprise corresponding to the enterprise information from the enterprise and business bureau.
In one implementation, the method for the first block link point device to determine whether the enterprise corresponding to the enterprise information is a credit enterprise according to the registration information may include: the first block chain node equipment obtains historical credit information of an enterprise corresponding to the enterprise information according to the registration information; the first block link point device detects whether the historical credit information indicates that the enterprise is a credit enterprise. The historical credit information may include, but is not limited to: the enterprise information corresponds to historical transaction data, risk management and control information and the like of the enterprise.
For example, if the first block link point device obtains the historical credit information indication of the enterprise corresponding to the enterprise information, and the credit level of the enterprise is low, the first block link point device may determine that the enterprise corresponding to the enterprise information is a low-credit enterprise.
In another implementation manner, the method for the first block link point device to determine whether the enterprise corresponding to the enterprise information is a credit enterprise according to the registration information may include: the first block chain node equipment compares the enterprise information with the registration information; and if the enterprise information is the same as the registration information, the first block link point device determines that the enterprise corresponding to the enterprise information is a credit enterprise.
For example, the first blockchain node device may request that the enterprise information sent by the second blockchain node includes all information included in the registration information, and then the first blockchain node device compares the content included in the enterprise information with the content included in the registration information, and if the content included in the enterprise information is the same as the content included in the registration information, it is determined that the enterprise corresponding to the enterprise information is a credit enterprise.
As can be seen, the first block link point device verifies the enterprise information provided by the invoicer, and if the verification is successful, the operation of step S506 is performed. The enterprise information provided by the invoicing party can be ensured to be real and reliable information, and the condition of virtual invoicing of the bill is further reduced.
Step S506: and if the enterprise information corresponds to the enterprise which is a credit enterprise, the first block link point device generates a digital certificate of the second block link point device.
In one implementation, the first block-link point device generates a digital certificate of the second block-link point device according to the registration information. Specifically, after the first block node device receives the biometric information sent by the second block node device, hash of the biometric information may be generated; and the first block chain node equipment generates a digital certificate containing the hash according to the registration information. Wherein the first tile linked-point device may generate a hash of the biometric information according to a hash algorithm.
Step S507: the first block link point device sends the digital certificate to the second block link point device.
Step S508: the first block link point device receives a ticket issuing request of the second block link point device.
Step S509: the first block link point device compares the digital certificate in the ticket issuing request with a digital certificate of a second block link point device stored by the first block link point device.
Step S510: and if the two are the same, the first block chain node equipment responds to the bill making request to generate a bill.
Step S511: the first block link point device sends the bill to the second block link point device.
Step S512: and the second block chain node equipment signs the bill according to the private key to obtain the digital signature of the bill.
Step S513: the second blockchain link point device issues the ticket, the digital signature and the digital certificate to a blockchain network.
It should be noted that the implementation process of step 507 to step 513 may refer to the implementation process of step S201 to step 206, and is not described herein again.
The first block chain node equipment verifies the identity information and the enterprise information sent by the second block chain node equipment respectively, the identity information and the enterprise information are verified successfully, and the first block chain node equipment issues the digital certificate of the second block chain node equipment. The identity information of the drawer can be ensured to be real and reliable, and the condition of false opening of the bill is further reduced.
It can be understood that after the second blockchain link point device issues the ticket, the digital signature and the digital certificate to the blockchain network, the first blockchain link point device can obtain the ticket, the digital signature and the digital certificate from the blockchain network, and the first blockchain link point device can trace back to the drawer who has issued the ticket according to the ticket, the digital signature and the digital certificate.
Referring to fig. 6, fig. 6 is a schematic flowchart of another method for issuing a ticket according to an embodiment of the present application, where the method includes:
step S601: the first block link point device acquires the ticket, the digital signature and the digital certificate.
Optionally, the first blockchain link point device acquires the ticket, the digital signature and the digital certificate from the blockchain network. Optionally, the first blockchain link point device may also obtain the ticket, the digital signature, and the digital certificate from a device outside the blockchain network.
Step S602: the first blockchain link point device compares the digital certificate obtained from the blockchain network with the digital certificate stored by the first blockchain link point device.
The first block link point device stores at least one digital certificate, and therefore the first block link point device compares the digital certificate of the second block link point device acquired from the block chain network with the digital certificate of the second block link point device stored in the first block link point device.
Step S603: and if the digital certificate acquired from the block chain network is the same as the digital certificate stored in the first block chain link point device, the first block chain node verifies and signs the digital signature.
In one implementation, the first block link point device verifies and signs the digital signature of the second block link point device obtained from the block chain network according to the public key of the second block link point device. According to the above, the second block chain node point device signs the bill according to the private key of the second block chain node point device, so as to obtain the digital signature. Therefore, the first block link point device can verify the digital signature according to the public key of the second block link point device, and if the verification is successful, the first block link point device determines that the digital signature is authentic.
Step S604: and if the signature verification is successful, the first block chain node equipment acquires the hash from the digital certificate and determines the identity information corresponding to the hash as the identity information associated with the bill.
Since the hash is generated from the biometric information of the drawer, there is an association between the hash and the drawer's identity information. Therefore, the first block chain node equipment acquires the hash from the digital certificate, and the drawer corresponding to the bill can be determined.
Therefore, the association relation is established between the bills and the drawer, so that the first block link point equipment can trace back the drawer who draws the bills according to the bills, and the condition of virtual opening of the bills is reduced.
