[0002] In order to attract users to make purchases, some merchants will provide parking coupons to users who have already made purchases. In the process of providing QR codes to users, merchants usually print fixed QR codes on paper or display them on data screens to allow users to scan and obtain parking coupons.

[0003] In actual scenarios, merchants usually need to pay a certain amount of money to obtain parking coupons from parking lot management. However, if the QR code provided by the merchant is fixed, usually just scanning the QR code can get the parking coupon. This makes the QR code provided by the merchant vulnerable to theft.

[0049] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of the embodiment of the present application is: receiving a coupon acquisition request sent by a user terminal, and reading the QR code identifier in the coupon acquisition request; if the QR code status corresponding to the QR code identifier is an activated state, sending the coupon to the user terminal; generating a random QR code according to the random QR code identifier, and updating the QR code display interface of the merchant terminal based on the random QR code.

[0052] Merchants usually need to pay a certain amount of compensation to obtain parking coupons from parking lot management to attract users to consume. In the related art, when merchants provide users with QR codes, they usually print the QR codes on paper or display them on a data screen to display fixed QR codes to users for them to scan and obtain parking coupons. When the QR codes provided by merchants are fixed, there are hidden dangers in the information security of the merchant's QR codes. Usually, parking coupons can be obtained by scanning the QR codes. This makes the QR codes provided by merchants vulnerable to theft, which affects the interests of merchants.

[0053] After receiving a coupon acquisition request based on a first QR code from a user terminal, the present application reads the QR code identifier in the coupon acquisition request, determines the QR code state corresponding to the QR code identifier, sends the coupon to the user terminal when the QR code state is activated, generates a random QR code at the same time, and updates the first QR code displayed on the data screen based on the random QR code. Each time the QR code on the data screen is used, it will become invalid and automatically updated, thereby ensuring the information security of the merchant's QR code, so that each QR code scanned by the user is a new QR code, avoiding the situation where the coupon is obtained unreasonably by scanning the QR code repeatedly or saving the QR code image, thereby protecting the interests of the merchant.

[0054] In order to better understand the above technical solution, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0055] It should be noted that the execution subject of this embodiment can be a coupon distribution system, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device that can achieve the above functions, a coupon distribution device, etc., which is not specifically limited in this embodiment. The following takes the coupon distribution system as an example to illustrate this embodiment and the following embodiments.

[0056] Based on this, the present application embodiment provides a coupon distribution method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the coupon distribution method of the present application.

[0057] In this embodiment, the coupon distribution method includes steps S10 to S30:

[0058] Step S10: receiving a coupon acquisition request sent by a user terminal, and reading a QR code identifier in the coupon acquisition request;

[0059] Step S20: If the QR code status corresponding to the QR code identifier is an activated status, the coupon is sent to the user terminal;

[0060] In this embodiment, the coupon issuance system includes a server, which is connected to the blockchain network and can perform data transmission and information exchange with the user end and the merchant end to complete the coupon issuance and other services. The user end is a terminal device such as a mobile phone or a tablet computer that can scan the QR code through a camera. After scanning the QR code displayed on the QR code display interface of the merchant end and decoding to obtain the QR code identifier of the QR code, a coupon acquisition request can be constructed based on the QR code identifier through an application (APP, Application), a public account or a web page, and the coupon acquisition request is sent to the server of the coupon issuance system. Among them, the coupon is a parking coupon, and the user can reduce the parking fee based on the coupon in the parking lot used.

[0061] Specifically, when the server receives the coupon acquisition request sent by the user terminal, it can read the QR code identifier in the coupon acquisition request. Each QR code identifier corresponds to a unique QR code, and the coupon issuance system can determine the QR code status of the target QR code and the QR code identifier based on the target QR code corresponding to the QR code identifier. The QR code status includes an activated state and an expired state. Among them, when the QR code status is an activated state, it means that the QR code has not yet issued a coupon, and when the QR code status is an expired state, it means that the QR code can no longer be used to obtain a coupon. When the coupon issuance system determines that the QR code status corresponding to the QR code identifier is an activated state, it will obtain or generate a coupon and send the coupon to the user terminal. Alternatively, if the QR code status corresponding to the QR code identifier is expired, the coupon issuance system will refuse to provide the coupon to the user terminal and send a prompt message to the user terminal that the QR code has expired.

[0062] Optionally, the method as described in step S20 includes steps S21 to S23:

[0063] Step S21: in the blockchain, obtaining the target QR code corresponding to the QR code identifier, and determining the QR code status of the target QR code;

[0064] Step S22: When the QR code is in an activated state, sending the coupon to the user terminal;

[0065] Step S23: updating the QR code status of the target QR code in the blockchain through the QR code status smart contract.

[0066] It should be noted that the blockchain network is a distributed system composed of multiple nodes, which stores data in multiple nodes in a decentralized manner and ensures the security and credibility of data through encryption algorithms and consensus mechanisms. The node can be a server, computer or other device connected to the blockchain network. The nodes in the blockchain network can perform data processing actions such as storage, forwarding and execution of smart contracts, and package the data processing actions into blocks, and broadcast the blocks to all nodes in the blockchain network, where each block contains the hash value of the previous block. At the same time, after receiving the block, all nodes in the blockchain network will determine the order and validity of adding new blocks based on the consensus mechanism of the blockchain network, so as to add the new blocks that have been agreed upon to the blockchain and update the ledger in the blockchain. Among them, the consensus mechanism can be selected from consensus mechanisms such as Proof of Work (PoW) and Proof of Stake (PoS). Based on multi-node storage, the blockchain network can achieve the immutability, reliability and transparency of data processing.

[0067] In the specific implementation, the blockchain network saves the QR code record and coupon generation information in the form of blockchain. At the same time, based on the QR code status smart contract, the QR code status is determined and updated. The coupon issuance system connects to the blockchain network, determines the target QR code corresponding to the QR code identifier in the blockchain, and obtains the QR code status. After the blockchain determines the QR code status corresponding to the QR code identifier based on the QR code status smart contract, the QR code status is fed back to the coupon issuance system. When the QR code status is activated, the coupon issuance system sends the coupon to the user terminal, which is saved in the electronic wallet by the user terminal. The coupon issuance system will also send the information on the completion of coupon issuance to the blockchain network, and the nodes in the blockchain network will simultaneously execute the QR code status smart contract, update the QR code status of the first QR code, and modify information such as the merchant coupon amount.

[0068] Exemplarily, based on the unmodifiable nature of blockchain, the QR code state is stored in the blockchain in the form of a state variable. The blockchain network can read and modify the state variable through the function in the QR code state smart contract. When the coupon issuance information based on the target QR code is received from the coupon issuance system, the function in the QR code state smart contract will be triggered, the state modification logic will be executed, the state variable will be updated from the activated state to the expired state, and the update will be broadcast to the blockchain network so that all nodes can verify and update their local state. The consensus mechanism of the blockchain ensures that all nodes agree on the changes in the data. When the state variable in the smart contract is modified, the modification will be packaged into a new block and propagated in the blockchain network through the consensus mechanism.

[0069] In an optional implementation, the coupon distribution system can also be directly deployed in the blockchain network in the form of a smart contract. In the blockchain network, all nodes receive coupon acquisition requests in the form of node servers, read the QR code identifier in the coupon acquisition request, and obtain the QR code status in the blockchain by executing the corresponding smart contract, and send the coupon to the user end when the QR code status is activated.

[0070] In another optional implementation, when the coupon issuing system is deployed in a server, the QR code and related information can also be saved in a database. After generating the QR code, the coupon issuing system will associate the QR code state, the QR code, and the QR code identifier with each other and save them in the database. The coupon issuing system determines the QR code state according to the QR code identifier through the database, and modifies the QR code state in the database.

[0071] Step S30: Generate a random QR code according to the random QR code identifier, and update the QR code display interface of the merchant terminal based on the random QR code.

[0072] In this embodiment, the coupon issuing system is also connected to the merchant terminal. The merchant terminal can be a data screen, or a terminal device equipped with a display screen such as a computer or a tablet computer. The merchant terminal can output the QR code display interface on the display screen or the data screen based on the preset rendering data, and receive the random QR code to be displayed generated by the server of the coupon issuing system for display. The random QR code is generated by the coupon issuing system and is used to update the QR code displayed on the data screen.

[0073] Specifically, the coupon distribution system generates a random QR code identifier through a random number generation algorithm. The random QR code identifier is binarized and encoded based on a preset QR code arrangement to generate the random QR code. The random QR code is sent to the merchant end, where the merchant end replaces the QR code currently displayed on the QR code display interface based on the received random QR code, so that the user end scans the updated QR code to obtain the coupon.

[0074] Exemplarily, the coupon distribution system generates a seed based on the current system time through a random number generation algorithm, and generates a target QR code identifier based on the seed. The target QR code identifier is binarized, arranged based on the layout of the QR code, and the arranged binary image is converted into a black and white image based on the method of black representing 1 and white representing 0, thereby generating a random QR code.

[0075] The embodiment of the present application reads the QR code identifier in the coupon acquisition request after receiving the coupon acquisition request based on the first QR code from the user end, and determines the QR code state corresponding to the QR code identifier. When the QR code state is activated, the coupon is sent to the user end, and a random QR code is generated at the same time. Based on the random QR code, the first QR code displayed on the data screen is updated. After each use, the QR code on the data screen will become invalid and automatically updated, thereby ensuring the information security of the merchant's QR code, so that the QR code scanned by the user each time is a new QR code, avoiding the situation where the coupon is obtained unreasonably by repeatedly scanning the QR code or saving the QR code image, and at the same time protecting the interests of the merchant.

[0076] Based on the same inventive concept, the present application also provides a second embodiment, referring to Figure 2 , Figure 2 This is a flow chart of the second embodiment of the coupon distribution method of the present application.

[0077] In this embodiment, as described in step S22, when the state of the QR code is in the activated state, after sending the coupon to the user terminal, steps S221 to S223 are also included:

[0078] Step S221: Determine the coupon smart contract corresponding to the target QR code in the blockchain;

[0079] Step S222: verifying the coupon acquisition request through the coupon smart contract;

[0080] In this embodiment, a coupon smart contract is stored in the blockchain, which includes but is not limited to the coupon acquisition rules of each merchant, and is used to verify the coupon acquisition request, determine whether the coupon acquisition request meets the coupon issuance conditions in the coupon acquisition rules, and the target amount, scope of use and other information of the issued coupon. The coupon acquisition request can optionally include consumption records and / or user terminal location information. The coupon issuance system can determine the corresponding merchant and the coupon smart contract corresponding to the merchant based on the QR code identifier and / or the target QR code and / or the coupon acquisition request, thereby verifying the coupon acquisition request based on the coupon smart contract through dimensions such as user location information and consumption records.

[0081] Optionally, the coupon smart contract includes a consumption smart contract and / or a positioning smart contract and / or an amount smart contract. Among them, the consumption smart contract identifies the merchant's coupon acquisition rules for the user's consumption record, which is used to determine whether the user's consumption meets the coupon issuance conditions. The positioning smart contract is used to verify whether the user's terminal location is within a reasonable range for obtaining coupons, rather than remotely scanning the QR code through photos or other methods to obtain coupons. The amount smart contract is used to verify whether the merchant's remaining coupon amount meets the coupon issuance conditions.

[0082] In the first implementation, the consumption smart contract is determined according to the merchant's coupon acquisition rules, and the user's consumption record can be verified, and the discount amount of the coupon can be determined based on the verification results. For example, when the coupon acquisition rule of the consumption smart contract is "a parking coupon worth 10 yuan will be given for consumption of 100 yuan or more", the consumption smart contract will automatically scan and analyze the user's dining consumption records. Once it is confirmed that the user's single consumption amount reaches or exceeds 100 yuan, the smart contract will immediately trigger the discount mechanism, automatically calculate and determine that the user should receive a parking coupon discount of 10 yuan. Subsequently, the coupon will be directly issued to the user's electronic wallet in digital form.

[0083] Optionally, the blockchain network can adjust the coupon smart contract based on upgrading the smart contract to adapt to the different smart contract requirements of merchants.

[0084] Optionally, the consumption smart contract can also be verified in the form of points. Merchants can assign corresponding points to users based on their consumption behavior. For example, when a user spends 100 yuan, 10 points are assigned. After obtaining the user's consumption record, the consumption smart contract can verify based on the points in the consumption record and determine the discount amount. For example, when the consumption smart contract automatically detects that the points in the consumption record are 10, a 10-yuan parking coupon will be assigned to the user. Among them, merchants can adjust the way users obtain points based on their own adjustments to the coupon acquisition rules, thereby avoiding frequent upgrades and updates of smart contracts that cause the blockchain network to be too redundant.

[0085] In the second implementation, the positioning smart contract needs to determine whether the user terminal is located within the reasonable position range for scanning the QR code to obtain the coupon. According to the positioning information of the user terminal in the coupon acquisition request, and according to the QR code identifier, the preset target positioning information is obtained. The target positioning information can be the positioning information of the merchant. By determining the positioning distance between the positioning information and the target positioning information, the positioning smart contract can verify the positioning distance. When the positioning distance is greater than the preset distance threshold, the abnormal prompt information of the abnormal position of the user terminal is output, or, when the positioning distance is less than the preset distance threshold, the coupon issuance action is performed normally.

[0086] In the third implementation, the amount smart contract will verify the remaining coupon amount of the merchant. After determining the merchant information corresponding to the QR code logo, the coupon amount of the merchant information is determined, and the coupon amount is verified according to the amount smart contract in the coupon smart contract. Among them, when the coupon amount is not zero, the coupon issuance system executes the coupon issuance action and updates the coupon amount according to the number of coupons generated. Optionally, the amount smart contract can also record the number of coupons issued by the merchant, and each time the coupon issuance system issues a coupon, the number of coupons issued by the merchant is added by one.

[0087] Step S223: Determine and generate the coupon according to the verification result.

[0088] In this embodiment, the coupon issuing system can determine the discount amount corresponding to the consumption record of the user terminal in the coupon acquisition request according to the verification result. At the same time, according to the target positioning information of the QR code, the target parking lot to which the coupon is applicable can be determined. The coupon issuing system generates a coupon according to the discount amount and the target parking lot.

[0089] Furthermore, after the coupon is generated, the blockchain network will package the coupon and coupon information and save them in the blockchain. At the same time, when the parking lot management system settles parking fees based on the user's identity information, it can also verify the coupon of the user's identity information through the coupon information saved in the blockchain.

[0090] The embodiment of the present application verifies the received coupon acquisition request through the coupon smart contract to determine whether the coupon issuance conditions are met, as well as the discount amount and discount amount of the issued coupon, thereby verifying the QR code issuance conditions and further reducing the risk of coupon theft.

[0091] Since the system introduced in the second embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of this application.

[0092] Based on the same inventive concept, the present application also provides a third embodiment, referring to Figure 3 , Figure 3 This is a flow chart of the third embodiment of the coupon distribution method of the present application.

[0093] In this embodiment, after generating a random QR code according to the random QR code identifier as described in step S30, and updating the QR code display interface of the merchant terminal based on the random QR code, steps S31 to S32 are also included:

[0094] Step S31: in the blockchain, obtaining the display time of the target QR code on the QR code display interface;

[0095] Step S32: Determine the display duration of the target QR code according to the display time and the current system time;

[0096] Step S33: When the display time is greater than the display time threshold, the random QR code is generated, and the QR code display interface of the merchant terminal is updated based on the random QR code.

[0097] In this embodiment, the blockchain records the display time of the target QR code currently displayed on the merchant's QR code display interface when it is put on the data screen, that is, the initial time when the target QR code is displayed. The coupon issuance system can determine the display time of the target QR code based on the display time and the current system time, and regularly update the QR code displayed on the data screen based on the display time threshold, that is, when the display time is greater than the display time threshold, generate a random QR code, and replace the target QR code displayed on the merchant's QR code display interface based on the random QR code, and use the random QR code as the new target QR code.

[0098] Optionally, the blockchain network can automatically trigger a smart contract through a smart contract when the display time of the QR code reaches a display time threshold, generate a random QR code, and update the target QR code displayed on the data screen.

[0099] The embodiment of the present application determines the display duration according to the display time of the QR code on the data screen, and updates the QR code displayed on the data screen when the display duration reaches a display duration threshold, thereby improving the security of the QR code.
