In the retail industry, more and more merchants send electronic coupons (such as coupons, group purchase coupons, vouchers, etc.) through the Internet, and use electronic coupons as carriers for various marketing activities. In order to solve the problems of trust, cost, efficiency and cooperation in the exchange of cards and coupons in the offline retail industry, a card and coupon trading platform built on the bottom of the blockchain has been launched, with card and coupon suppliers and card and coupon purchases. Merchants use the card and coupon trading platform to match, and use the blockchain as the bottom layer to realize card and coupon life cycle management and clearing and reconciliation. Since a considerable part of the cards and coupons on the market currently adopt the mode of bearer redemption codes, the products can be exchanged directly by using the redemption codes, and the card and coupon trading platform is based on the blockchain and the information on the chain is open and transparent, so sensitive redemption is required Code to establish a corresponding protection mechanism.

At present, there are mainly two protection mechanisms for card and coupon redemption codes: 1) The redemption codes are kept by the card and coupon suppliers themselves and are not chained. Although this method of management is simple, it cannot realize the life cycle management of coupons and coupons on the chain. The issuance and verification of coupons and coupons are done unilaterally by the supplier. If the supplier has false verification, it will cause the purchaser Loss; 2) The redemption code is on the chain. Although this method is more open and transparent, because of the sensitivity of the redemption code, the chain means that encryption must be performed. The encryption requires the management of key pairs for each merchant, and both the chaining and pulling data from the chain need to be performed Encryption and decryption, the process is complicated, and the management difficulty is greatly increased.

Based on the above hardware structure, an embodiment of the card management method of this application is proposed.

Referring to Fig. 2, Fig. 2 is a schematic flowchart of a first embodiment of a card and coupon management method according to this application. The method includes:

Step S10, when it is detected that the coupon purchase order is created, the redemption code of the coupon purchased by the coupon purchase order is obtained;

In this embodiment, coupons refer to electronic coupons such as coupons, group purchase coupons, and vouchers. The application scenario of this embodiment may be: a certain company wants to issue benefits to employees in the form of issuing cards and coupons, or wants to provide points redemption on its own mall by purchasing cards and coupons from other companies to provide more for its own customers. When multi-equity value is exchanged, it can be used as a card purchaser to purchase cards and coupons on the card and coupon trading platform, and then distribute the purchased cards and coupons to client users who meet the issuance conditions for client users to use.

In the above process, the life cycle of a coupon refers to the entire process of a coupon from being created, to being activated, and to verification or invalidation. In order to realize the openness and transparency of card and coupon life cycle management, the card and coupon management method of this embodiment is applied to a card and coupon trading platform built with a blockchain as the bottom layer. Card and coupon suppliers and card and coupon purchasers are matched through the card and coupon trading platform. , And use blockchain as the bottom layer to realize card and coupon life cycle management and clearing and reconciliation.

During specific implementation, you can first obtain the coupons and coupons and redemption codes created by the coupon supplier on the coupon trading platform, and then save the created coupons and coupons and redemption codes in a card coupon redemption code pool; purchasers purchase cards When purchasing coupons, you can place an order on the coupon trading platform based on the denomination of the coupons you want to purchase, the type of coupons, and the number of coupons. When the coupon trading platform detects that the coupon purchase order has been created, the coupon purchase order can be obtained. Order the purchased coupons and find the redemption code pool to get the redemption codes of the purchased coupons. Among them, the redemption code refers to a character string that can be directly exchanged for a commodity, and it is anonymous. Different suppliers have their own generation rules, such as a mixed character string of 16 letters and numbers.

Step S20: Obtain a pre-stored code code corresponding to the redemption code, and generate a code mapping code corresponding to the code, wherein the redemption code, the code, and the code mapping code correspond one-to-one;

In this step, after the redemption code of the purchased coupons is obtained, the code corresponding to the redemption code preset and stored locally on the coupon trading platform is further obtained, and a code mapping code corresponding to the code is generated. Among them, the redemption code, code and code mapping code correspond one-to-one. The code is a character string generated by the coupon trading platform itself. There will be no repeated activation codes for the same type of coupons, and the code after verification can be reused; code The mapping code is a character string generated by numbering the code according to the relationship between the coupon purchase order and the code.

Step S30: Obtain the current state of the coupon during the preset full life cycle, and set the state to the state of the code mapping code;

In this step, take the preset full life cycle of the coupons and coupons as created-activated-written off as an example. After the coupon purchase order is created, the status of the coupons purchased can be changed from the original created Marked as activated means that the coupon can be used by the user; when the coupon is used and verified, the status of the coupon can be marked as verified.

In this embodiment, after generating the code mapping code, the card and coupon trading platform further obtains the state of the currently purchased card and coupon in the preset full life cycle, and sets the obtained state as the generated code mapping code status. Since the redemption code, code, and code mapping code have a one-to-one correspondence, the status of the code mapping code can also be regarded as the status of the redemption code and code, that is, the status of the redemption code, code, and code mapping code remains the same.

Step S40: After associating the code mapping code, the status of the code mapping code, and the coupon purchase order, they are sent to the blockchain for storage.

After setting the status of the code mapping code, associate the code mapping code, the status of the code mapping code and the card purchase order, and then send them to the blockchain for storage. As a result, the life cycle of coupons can be managed based on the blockchain.

Referring to FIG. 3, FIG. 3 is a schematic diagram of the system architecture of the card management method in an embodiment of the application. Among them, the card and coupon trading platform can interact with the blockchain. In the card and coupon trading platform, there is a one-to-one correspondence between the redemption code, code and code mapping code. The redemption code and code are not directly linked to the chain, but the code mapping code is uploaded. The status of the code mapping code on the chain is the actual redemption code and the status of the code. The current order in the figure corresponds to the three code mapping codes code1, code2 and code3. The statuses are activated, activated, and written off respectively. When the status of the code changes, correspondingly modify the status of the code mapping code on the chain to realize the card coupon life cycle management on the blockchain.

In this embodiment, by uploading the code mapping code and its status to the chain, the on-chain life cycle management of cards and coupons is realized without disclosing the redemption code. Since the code mapping code is double-mapped for the redemption code It is obtained that even if the code mapping code on the chain is public, it is difficult to steal the corresponding card and coupon redemption code, which fully guarantees the security of the card and coupon redemption code, and also makes the code mapping code need not be encrypted when it is chained, thereby saving Going to set up key pair, encryption and decryption management procedures, greatly reducing the difficulty of card management.

Further, based on the first embodiment of the card and coupon management method of the present application, a second embodiment of the card and coupon management method of the present application is proposed.

In this embodiment, before the above step S10, it may further include: receiving a coupon creation request and a redemption code import request sent by a supplier node; creating a corresponding coupon according to the coupon creation request, and importing a coupon according to the redemption code Request to assign a corresponding redemption code to the created coupons; generate a code corresponding to each redemption code; place the created coupons, the assigned redemption codes, and the code corresponding to each redemption code locally Save it encrypted.

In this embodiment, the supplier can first create the coupons to be sold on the coupon trading platform and import the redemption code corresponding to the coupons. The coupon trading platform receives the coupon creation request and the coupon creation request sent by the supplier node. When the redemption code import request, create the corresponding card and coupon, and assign the corresponding redemption code to the created card and coupon. For the redemption code, different suppliers have their own generation rules, which are not limited in this embodiment; then, the generation is related to each The code corresponding to each redemption code, the specific generation method can be to generate a string according to preset rules, such as generating a 30-digit decimal code (16-digit 62-digit converted to decimal, the longest is 29 digits), and guarantee The code corresponding to different redemption codes is different; after that, the coupon, redemption code and code are associated and encrypted and stored locally. The encryption algorithm can be a symmetric encryption algorithm or a hash encryption algorithm such as MD5.

Through the above method, a prerequisite guarantee is provided for subsequent acquisition of the redemption code and code corresponding to the card and voucher, and a prerequisite guarantee for the verification of the card and voucher based on the redemption code and code.

Further, based on the first embodiment of the card and coupon management method of the present application, a third embodiment of the card and coupon management method of the present application is proposed.

In this embodiment, before step S40, the method may further include: sending the code to a buyer node, so that the buyer node can issue the code to the client of the buyer node.

Specifically, after associating the code mapping code, the status of the code mapping code, and the card purchase order and sending it to the blockchain for storage, the code can be encrypted and sent to the buyer node, so that the buyer node can When the code is issued to the client, the client user obtains the code, which means that they have the rights to exchange cards and coupons. For example, when a point platform is deployed on the purchaser node, the platform user uses points to redeem cards and coupons. At this time, the card and coupon code can be sent to the user, and the user obtains the card and coupon redemption rights.

Further, the card and coupon management method may further include: when a card and coupon exchange request sent by the client is received, obtaining a code carried in the card and coupon exchange request; and obtaining a pre-saved exchange code with the card and coupon The redemption code corresponding to the code carried in the request is returned to the client.

In this embodiment, when the card and coupon transaction platform receives the card and coupon redemption request sent by the client, it obtains the code carried in the card and coupon redemption request, then obtains the pre-stored redemption code corresponding to the code, and exchanges it The code is returned to the client. This method of pulling the corresponding redemption code through the code ensures that the client user can use the coupons corresponding to the redemption code normally.

Further, based on the first, second and third embodiments of the card and coupon management method of this application, a fourth embodiment of the card and coupon management method of this application is proposed.

In this embodiment, the card and coupon management method may further include: receiving a card and coupon verification request, the card and coupon verification request carrying the redemption code or code of the coupon to be verified; The redemption code of the card or coupon to be verified or the target code mapping code corresponding to the code; a verification request based on the target code mapping code is initiated to the blockchain, so that the participating nodes of the blockchain can respond to the target The code mapping code performs the verification of the consensus, and after the consensus is reached, the status of the target code mapping code on the blockchain is marked as the verified state; when the verification is completed, the verification returned by the blockchain is received When sending information, mark the redemption code and code status corresponding to the target code mapping code stored locally as the written-off status.

Specifically, in this embodiment, the voucher verification request may be initiated by the supplier or the purchaser. When initiated by the supplier, the voucher verification request carries the redemption code of the voucher to be verified. When initiated by the purchaser, the voucher verification request carries the code of the voucher to be verified; when the voucher verification request is received by the voucher verification request, the card and voucher transaction platform obtains the pre-saved redemption code or the voucher to be verified. code corresponding to the target code mapping code, and then initiates a verification request based on the target code mapping code to the blockchain, so that the participating nodes of the blockchain can perform a verification consensus on the target code mapping code, and the consensus is reached After that, the status of the target code mapping code on the blockchain is marked as the verified state, which means that the coupon corresponding to the target code mapping code has been verified.

As a result, the verification of the card and coupon based on the blockchain is realized. The redemption code of the verification process is always encrypted and stored locally on the card and coupon trading platform, thereby ensuring the security of the redemption code while managing the life cycle on the chain.
