Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
The embodiment of the invention provides a block chain-based credit card transaction method which can be applied to but not limited to a credit card transaction business system of any bank.
Fig. 1 is a flowchart of a block chain-based credit card transaction method provided in an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
s101, receiving a credit card transaction request from a client, wherein the credit card transaction request at least comprises identification information of a target user applying for credit card transaction.
It should be noted that the credit card transaction request received in S101 may be a request for the target user to apply for transaction of a credit card to any bank; in the embodiment of the present invention, the identification information of the target user included in the credit card transaction request may be information that can be used to uniquely identify the target user, for example, an identity card number or a mobile phone number.
And S102, inquiring the user information of the target user from the block chain network according to the identification information of the target user.
It should be noted that the blockchain network in the embodiment of the present invention may be a blockchain network constructed by using each bank end as a blockchain storage node; or a single blockchain network, and each bank terminal accesses the blockchain network through a blockchain client terminal.
In the implementation, the user information of the target user may be stored in the blockchain network in advance. In one embodiment, the block chain based credit card transaction method provided in the embodiment of the present invention may further store information required for a user to transact a credit card to the block chain network in advance by: collecting user information input by a target user when applying for transacting a credit card for the first time; and storing the collected user information to the block chain network. Through the embodiment, the user information input when a user applies for transacting the credit card for the first time in a certain bank is stored in the blockchain network, and the user information can be conveniently used when other banks apply for transacting the credit card subsequently.
S103, judging whether the target user meets the credit card transaction condition or not according to the user information of the target user.
It should be noted that, the credit card transaction conditions required by different banks are different, and in the embodiment of the present invention, the credit card transaction conditions for each bank to transact credit cards may be configured in advance according to specific situations. For example, for most banks, each user is often required to apply for only one credit card, and thus, the credit card transaction condition in S103 may be to check whether the target user has a transacted credit card in the target bank (i.e., the bank that requested to transact the credit card by the credit card transaction request received in S101), and if not, it indicates that the target user meets the credit card transaction condition; if the credit card exists, the target user is not qualified for the credit card transaction condition.
And S104, verifying the identity information of the target user under the condition that the target user meets the credit card transaction condition.
In a specific implementation, the step S104 may be implemented by: sending a video verification request to a client; receiving a video image returned by the client according to the video verification request; and verifying the identity information of the target user according to the video image returned by the client. Optionally, in the embodiment of the present invention, the video image may be a video image recorded when the user performs a preset action (for example, blinking, turning, nodding), so as to avoid a situation that others use the user's photo to verify the identity information.
In one embodiment, a video authentication request is sent to the client through a 5G message, and a video image returned by the client according to the video authentication request is received. In the embodiment, the video image is transmitted through the 5G message, so that the transmission rate of the video image can be greatly improved, and the real-time verification of the user identity information is realized.
When the identity information of the target user is checked according to the video image returned by the client, the electronic image of the identity card of the target user can be inquired from the blockchain network; and then verifying whether the video image returned by the client is operated by the user or not according to the electronic image of the identity card.
And S105, when the identity information of the target user passes the verification, executing credit card transaction service corresponding to the credit card transaction request according to the user information of the target user stored in the block chain network.
In an embodiment, after performing a credit card transaction service corresponding to a credit card transaction request according to user information of a target user stored on a blockchain network, the method for credit card transaction based on a blockchain provided in an embodiment of the present invention may further include the following steps: acquiring credit card information successfully applied and transacted by a target user; and updating the user information of the target user on the block chain network according to the credit card information successfully transacted by the target user application. In the embodiment, the user information of the target user on the block chain network is updated according to the credit card information successfully transacted by the user application, so that the subsequent verification of the credit card transacting condition can be facilitated.
The credit card transaction method based on the block chain provided by the embodiment of the invention enables a user to efficiently and conveniently transact credit cards of multiple banks simultaneously.
FIG. 2 is a flow chart of a credit card transaction implementation according to an embodiment of the present invention, as shown in FIG. 2, when a user needs to apply for the transaction of a credit card, the user information of the user stored on the block chain network is queried according to application information (including but not limited to an identification number, bank information of a first bank, and bank information of a second bank) included in a request for the transaction of the credit card, and whether the user has a credit card at the bank where the user applies for and does not apply for the credit card any more is determined according to the queried user information; and after the user records the portrait video, the portrait video is sent to the corresponding bank terminal through a 5G message. After receiving a portrait video of a user, a bank side firstly queries user information (including but not limited to an identity card number, an identity card photo and the like) of the user in a block chain according to the identity card number; and verifying the identity information of the user to determine whether the operation of applying for transacting the credit card is the operation of the user. When the user identity information passes the verification, the basic information (including but not limited to name, mobile phone number, identity card photo, home address, etc.) of the user is inquired in a block chain according to the identity card number, the user information is simultaneously sent to all bank terminals of the user applying for transacting the credit card through 5G information, and corresponding credit card transacting business is executed. After applying for and transacting the credit card successfully, the bank returns the credit card number, and the credit card number is updated in the basic information of the block chain user. And simultaneously, the user is informed that the application of the credit card of a certain bank is successful.
