Specifically, the method of the embodiment of the present invention includes the following steps.
S201: and acquiring a tax refund request, wherein the tax refund request carries an invoice identifier.
In the embodiment of the invention, a node can obtain a tax refund request, wherein the tax refund request carries an invoice identifier, and the node is any one of a plurality of nodes in a block chain network. In some embodiments, the invoice identifier includes, but is not limited to, any one or more characters of numbers, letters, words, etc., and in one example, the invoice identifier may be a number.
In one embodiment, the node may receive a tax refund request sent by a user through a tax refund device when obtaining the tax refund request. In one embodiment, the tax refund device may include a tax refund interface, and the user may input tax refund information such as an invoice identifier, an identity identifier, and the like on the tax refund interface. The user can use the tax refunding device to input tax refunding information such as invoice identification, identity identification and the like after the customs is released in an airport, the tax refunding device can generate a tax refunding request according to the tax refunding information input by the user, and the user sends the tax refunding request to the tax block chain by selecting a tax refunding control on the tax refunding device, so that a node in the tax block chain can receive the tax refunding request sent by the user through the tax refunding device. In some embodiments, the identification may include, but is not limited to, any one or more of a passport number, an identification number, and the like. In some embodiments, the tax blockchain is a blockchain in the aforementioned blockchain network.
For example, after a user enters customs at an airport, an invoice identifier and a passport number may be input by using a tax refund device, the tax refund device may generate a tax refund request according to the invoice identifier and the passport number input by the user, and the user may send the tax refund request to the tax block chain by selecting a tax refund control on the tax refund device, so that a node in the tax block chain may receive the tax refund request sent by the user through the tax refund device.
In one embodiment, before receiving a tax refund request sent by a user through a tax refund device, the node may obtain bill information of an electronic invoice sent by an invoicing terminal after the electronic invoice is issued for a consumption transaction of the user and an identity of the user, and the node may write the bill information and the identity into a block after binding the bill information and the identity, and broadcast the block to other nodes in the plurality of nodes, so that the block is added into a tax block chain when the other nodes verify the block. By the implementation mode, tampering is effectively prevented, and the effectiveness and traceability of tax refund data are ensured.
In one embodiment, the node may obtain the bill information of the electronic invoice and the identity of the user, which are sent by the billing terminal after the electronic invoice is issued for the consumption transaction of the user, and calculate the summary information of the bill information and the summary information of the identity of the user. The node may bind the correspondence between the digest information of the ticket information and the digest information of the user's identification, and write the bound information into a block, and broadcast the block to other nodes of the plurality of nodes, so that the block is added to a tax block chain when the other nodes verify the correspondence between the digest information of the ticket information and the digest information of the user's identification in the block. By this embodiment, the non-tamper-ability of the tax refund information is ensured.
In one embodiment, the node may receive a tax refund request sent by the tax refund device upon verifying that the invoice identification entered by the user matches the identity identification, before receiving the tax refund request sent by the user through the tax refund device. In one implementation, a user may input an invoice identifier and an identity identifier through a tax refund device, and verify the invoice identifier and the identity identifier, and if the invoice identifier input by the user is matched with the identity identifier through verification, the tax refund device sends a tax refund request to a node of a block chain, so that the node may receive the tax refund request sent by the user through the tax refund device. By the implementation mode, the tax refund can be requested on the premise of ensuring the identity safety of the user, and the safety of the tax refund operation is improved.
In an embodiment, when receiving a tax refund request sent by a user through a tax refund device, the node may receive the tax refund request sent by the tax refund device after successfully identifying a graphic code displayed by a designated application on a user terminal corresponding to the user, where the graphic code includes bill information of the electronic invoice sent by the invoicing terminal to the user terminal. In some embodiments, the graphical code may include, but is not limited to, any one or more of a two-dimensional code, a bar code, and the like. By the implementation mode, the complexity of tax refund operation is reduced, and the flexibility of tax refund is improved.
In one example, after issuing an electronic invoice for a consumer transaction of a user, a billing terminal may generate a corresponding graphic code according to bill information of the electronic invoice and send the graphic code to a user terminal of the user, and the user may store the graphic code in a designated application of the user terminal through the user terminal. When the user is in the outbound, the graphical code can be scanned through the tax refund device, and when the tax refund device successfully identifies the graphical code, a tax refund request can be sent to the node.
For example, after the billing terminal issues an electronic invoice for a consumer transaction of a user, a corresponding two-dimensional code may be generated according to the bill information of the electronic invoice, and the two-dimensional code is sent to the user terminal of the user, and the user may store the two-dimensional code in a designated application of the user terminal through the user terminal. When the user is in the outbound, the two-dimension code can be scanned and identified through the tax refunding device, and when the two-dimension code is successfully identified through the tax refunding device, bill information corresponding to the two-dimension code can be obtained, a tax refunding request is generated according to the bill information, and the tax refunding request is sent to a node of the tax block chain.
In one implementation, after a user successfully identifies a graphic code designated for application display on a user terminal corresponding to the user, an invoice identifier and an identity identifier corresponding to the graphic code may be obtained, the invoice identifier and the identity identifier are verified, and if the invoice identifier and the identity identifier input by the user are verified to be matched, the tax refund device sends a tax refund request to a node of a block chain, so that the node may receive the tax refund request sent by the user through the tax refund device. By the implementation mode, the tax refund can be requested on the premise of ensuring the identity safety of the user, and the safety of the tax refund operation is improved.
For example, after the user successfully identifies the two-dimensional code displayed by the designated application on the user terminal corresponding to the user, the user may obtain an invoice identifier and a passport number corresponding to the two-dimensional code, and verify the invoice identifier and the passport number, and if the invoice identifier input by the user is matched with the passport number through verification, the tax refund device sends a tax refund request to a node of the block chain, so that the node may receive the tax refund request sent by the user through the tax refund device.
S202: and calling the intelligent contract to generate a tax refund transaction corresponding to the invoice identification, wherein the tax refund transaction comprises a tax refund amount and an account specified by the user.
In the embodiment of the invention, the node can call the intelligent contract to generate the tax refund transaction corresponding to the invoice identifier, wherein the tax refund transaction comprises tax refund amount and an account specified by a user. In some embodiments, the intelligent contracts are explained as previously, and are not described in detail herein.
In an embodiment, the tax refund request further carries an identity, before the node invokes the intelligent contract to generate the tax refund transaction corresponding to the invoice identity, the node may obtain first summary information of the invoice identity carried in the tax refund request and second summary information of the identity, and query whether the invoice identity carried in the tax refund request and the identity are matched from the tax block chain according to the first summary information and the second summary information, and if so, execute the step of invoking the intelligent contract to generate the tax refund transaction corresponding to the invoice identity.
In one embodiment, the node queries, according to the first summary information and the second summary information, whether a correspondence between the summary information of the invoice identifier carried in the tax refund request and the summary information of the identity identifier carried in the tax refund request matches a correspondence between the first summary information and the second summary information from the tax block chain, and if so, executes the step of invoking the intelligent contract to generate the tax refund transaction corresponding to the invoice identifier. By the implementation mode, tampering is effectively prevented, false tax return is avoided, and the safety of tax return is ensured.
S203: and sending the tax refund transaction to a tax terminal so that the tax terminal refunds to the account designated by the user according to the tax refund transaction.
In the embodiment of the invention, the node can send the tax refund transaction to the tax terminal so that the tax terminal refunds to the account appointed by the user according to the tax refund transaction. In one example, the user-designated account may be the user-designated bank account.
In an embodiment, the tax refund request further carries an identity, and before the node sends the tax refund transaction to the tax terminal, the node may send an inquiry request to an entry and exit management center, where the inquiry request includes the identity carried in the tax refund request. The node can acquire the entry and exit information which is sent by the entry and exit management center and corresponds to the identity identification, determine whether the user corresponding to the identity identification is out according to the entry and exit information, and send the tax refund transaction to the tax terminal if the user is determined to be out, so that the tax terminal refunds to an account specified by the user according to the tax refund transaction. By the implementation mode, the user can be ensured to return the tax after the user is out of the country, and safe tax return is realized.
For example, after calling an intelligent contract to generate a tax refund transaction corresponding to an invoice identifier in a tax refund request, a node may send an inquiry request to an entry and exit management center, where the inquiry request includes an identity identifier a carried in the tax refund request. The node can acquire the entry and exit information which is sent by the entry and exit management center and corresponds to the identity mark A, and determine whether the user corresponding to the identity mark A exits according to the entry and exit information, if the user is determined to exit, the node can send the tax refund transaction to the tax terminal, so that the tax terminal refunds to an account appointed by the user according to the tax refund transaction.
In the embodiment of the invention, the node can generate the tax refund transaction corresponding to the invoice identifier carried in the tax refund request by acquiring the tax refund request and calling the intelligent contract, wherein the tax refund transaction comprises the tax refund amount and the account specified by the user, so that the tax refund transaction is sent to the tax terminal, and the tax terminal refunds to the account specified by the user according to the tax refund transaction. Through the implementation mode, the automatic and intelligent requirements of the user on tax refund can be met, the tax refund efficiency is improved under the condition of ensuring the safety, and the consumption experience of the user is improved.
