Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a method for issuing an electronic card based on a block chain, including:
s101, deploying a blockchain platform based on the blockchain framework, and deploying the card and ticket issuing platform and the user in the blockchain platform by taking the card and ticket issuing platform and the user as nodes.
The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database.
A blockchain platform is first deployed based on the blockchain framework. The blockchain frame may be any blockchain frame capable of implementing the corresponding function of the embodiment of the present application, for example, bitcoin, etherhouse, Fabric, Corda, and the like. A blockchain platform may refer to a platform that stores a blockchain, e.g., may be a distributed system, etc. Of course, the blockchain platform may also directly represent the blockchain itself, and is not limited herein.
And then, the card issuing platform for issuing the electronic card and the user are taken as nodes and deployed in the block chain platform. The electronic card issued by the card issuing platform can be a coupon, that is, when the user purchases corresponding goods or services, the price of the purchase can be reduced through the coupon. The electronic card ticket may be in other forms such as a membership card and a deposit card, and is not limited herein.
S102, receiving the card information sent by the card issuing platform, wherein the card information comprises a card number and a random verification code.
After the regional cross-chain platform is deployed, if the card ticket issuing platform wants to issue the electronic card tickets, the card ticket information of the electronic card tickets which want to be issued is sent to the block chain platform. After receiving the card information, the blockchain platform can perform corresponding storage. The card information comprises a card number and a random verification code, and the random verification code is used for verification.
Further, the card information may further include other data, such as at least one of a corresponding item link, a corresponding item type, a usage requirement, a usage mode, a lifetime, a value, and a dispensing time. When the electronic card is a coupon, the electronic card corresponds to a corresponding commodity, and the card information may include a commodity link and a commodity type of the commodity. The usage requirement may be, for example, that the electronic card coupon is a coupon, and the consumer can use the coupon when the coupon is full. The usage pattern can be, for example, when the electronic card ticket is a membership card, when the platform is available, when the price is settled, when a shopping cart is added, or the like. The lifetime may be described in terms of a duration, an expiration time, etc. The value may be, for example, a price that can be reduced when the electronic card is a coupon, a price that can be reduced per purchase when the electronic card is a membership card, or the like. The issuing time is the time of issuing the electronic card.
S103, encrypting the random verification code through the public key of the user to obtain an encrypted verification code; and hashing the random verification code to obtain a hash verification code.
S104, writing the card information carrying the encryption verification code and the Hash verification code into the block chain platform.
In obtaining the card information, the blockchain platform may encrypt the random verification code included in the card information by the public key of the user to obtain an encrypted verification code. And then, hashing the random verification code to obtain a hashed verification code. Wherein the user prepares an object for the card issuing platform to issue the electronic card.
And after the encrypted verification code and the Hash verification code are obtained, writing the card information carrying the encrypted verification code and the Hash verification code into the block chain platform. Since the data in the blockchain platform is public, each node can acquire the data therein, and therefore, a user as a node can also acquire the encrypted verification code and the hashed verification code.
S105, decrypting the encrypted verification code through the private key of the user to obtain the verification code to be confirmed.
S106, if the hash value obtained after the verification code to be confirmed is hashed is consistent with the hash verification code, the electronic card is issued to the user, and the identity information and the receiving time of the user are written into the block chain platform.
After the user acquires the encrypted verification code and the hash verification code, the encrypted verification code can be decrypted through the private key of the user, so that a decrypted random verification code is obtained, and the decrypted random verification code is called as a verification code to be confirmed. Certainly, the private key of the user can be hosted by the blockchain platform, that is, the user informs the blockchain platform of the private key, and then the blockchain platform decrypts the private key of the user to obtain the verification code to be confirmed.
And then comparing the hash value of the verification code to be confirmed after hashing with the hash verification code. If the electronic card information is consistent with the user identity information, the electronic card information of the electronic card is not tampered, and the user identity information is not wrong, the electronic card can be issued to the user, and after the electronic card is issued, the user identity information and the picking time are written into the block chain platform. The issuing process of the electronic card may be the issuing process by binding the card number of the electronic card with the account of the user, which is not described herein again. The issuing process of the electronic card is stored in the block chain platform, and the data in the block chain platform is public and transparent, so that the user can trace the issuing of the electronic card through a corresponding way at any time. And because the blockchain platform is in distributed storage, data tampering of a single node cannot be effective, and the truthfulness and the credibility of the data on the blockchain platform are ensured. The system can trace the source through related approaches regardless of any node in the card and ticket issuing platform or the user, and once the user thinks that the issuing process of the electronic card and the ticket has problems, the user can confirm through data in the block chain platform at any time so as to maintain the rights and interests of the user.
Further, the user information and the pickup time of the user can be written into the block chain platform and the block where the card information is located. The user or other nodes can conveniently inquire the information corresponding to the electronic card, and corresponding information does not need to be searched from other blocks.
In one embodiment, the blockchain platform may be deployed through a hyper book fabric. Fabric is known as HyperLegendr Fabric and is a licensed blockchain architecture (licensed blockchain architecture). It was originally contributed to the Hyperridge project by IBM and Digital Asset. A Fabric network comprises Peer nodes (Peernodes) executing the chalnode contract, accessing ledger data, endorsing transactions and being called an interface of an application program. The commander nodes (Orderer nodes) are responsible for ensuring the consistency of this block chain and communicating endorsed transactions to peers in the network; and an MSP service that manages x.509 certificates primarily as Certificate authorities (Certificate authorities) for verifying membership and roles.
In one embodiment, the corresponding intelligent contracts may also be generated in advance and deployed in the blockchain platform. The intelligent contract comprises an encrypted verification code, a random verification code and a hash verification code. The intelligent contract is used for decrypting the encrypted verification code to obtain a verification code to be confirmed after receiving a private key of the user, then comparing a hash value of the verification code to be confirmed after hashing with the hash verification code, and if the hash value is consistent with the hash verification code, issuing the electronic card to the user. Since the intelligent contracts on the blockchain platform are public, each node can check whether the intelligent contracts are in accordance with the preset agreement or not and deploy the intelligent contracts on the own node. The user can inquire the intelligent contract through a corresponding way, so that the degree of automation of the transaction is improved, and the trust degree of the user is further increased. The intelligent contract can only be changed in an upgrading mode, each node needs to be synchronously deployed, once the intelligent contract is deployed, the intelligent contract can only be executed through a program, interference of human factors is avoided, and the reliability of data is enhanced.
In one embodiment, if the electronic card coupon is a coupon, a commodity link corresponding to the coupon can be further determined, and the commodity link is written into the block chain platform through the coupon information. For example, when the coupon is for a certain product of a certain e-commerce platform, a link for the product may be written into the blockchain platform. If the electronic card ticket is a membership card, the official network link of the merchant corresponding to the membership card can be written into the block chain platform through card ticket information. By writing the commodity link or the official network link of the merchant into the blockchain platform, the user can find the corresponding commodity or merchant more conveniently, and the electronic card ticket is used more conveniently.
In an embodiment, if the number of the card information is multiple, the multiple pieces of card information may be sorted according to the commodity types corresponding to the card information and the preset corresponding relationship, and then the card information carrying the encrypted verification code and the hashed verification code is written into the block chain platform in sequence according to the sorting result. Because different commodity types have different use time limits, for example, the use time limits of fresh and fresh fruits and vegetables are lower, the card coupon information corresponding to the part of commodity types is preferentially written into the block chain platform, so that a user can acquire the corresponding card coupons as soon as possible.
