Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings. The exemplary embodiments of the present invention and their descriptions herein are for the purpose of explaining the present invention, but are not to be construed as limiting the invention.
Fig. 1 is a flowchart of a cross-line withdrawal method based on blockchain and face recognition in an embodiment of the present invention, as shown in fig. 1, the method includes:
step 101: storing account information and face images submitted by a customer when the customer first transacts cards in a block chain;
step 102: receiving a customer face image recorded by an ATM when a customer withdraws through the ATM, carrying out matching identification on the recorded customer face image and the face image stored in the block chain, and acquiring account information and returning the account information to the ATM after successful identification;
step 103: receiving withdrawal information sent by the ATM after the ATM judges to carry out the cross-line withdrawal based on the account information, sending a transfer record to a corresponding bank based on the withdrawal information, and transferring a corresponding amount to the bank to which the ATM belongs by the corresponding bank based on the transfer record;
step 104: after receiving the transfer success message, sending a withdrawal notification to the ATM, and carrying out cross-line withdrawal by a customer;
step 105: and updating account information after receiving a customer withdrawal success message sent by the ATM.
Specifically, in step 101, when a customer first checks a card at a website, the account information and the face image of the customer are stored in a blockchain for subsequent face image recognition and recognition to obtain the information of the bank card of the customer. Wherein the account information includes: name, document type, document number, bank card number, balance, account opening, etc.
In step 102, when a customer withdraws money through an ATM, the ATM first records a face image of the customer, then transmits the face image to a face image stored in a blockchain for matching identification (identity), and after successful identification, obtains account information of all bank cards and the like under the customer name from customer account information stored in the blockchain, and returns the account information to the ATM.
In the embodiment of the invention, the account information comprises a plurality of pieces of bank card information;
the ATM judges whether to carry out the cross-line withdrawal or not based on the account information according to the following mode:
displaying information of a plurality of bank cards by the ATM;
receiving one or more bank cards to be deducted selected by a customer based on the information of the plurality of bank cards;
the ATM judges whether to carry out the cross-line withdrawal or not based on the selected one or more bank cards to be deducted.
In an embodiment of the present invention, as shown in fig. 2, the method further includes:
step 201: and receiving a withdrawal success message sent by the ATM after judging non-cross-line money based on the account information, wherein the ATM directly carries out withdrawal transaction when judging that the ATM withdraws in the non-cross-line area.
In the embodiment of the invention, the withdrawal information comprises a deducted bank card and a withdrawal amount selected by a customer through an ATM;
as shown in fig. 3, further includes:
step 301: judging whether the balance of the deducted bank card is sufficient or not based on the withdrawal amount, and if so, sending a transfer record to a corresponding bank based on the withdrawal information; if not, sending a withdrawal failure message to the ATM, and reselecting the deduction bank card by the client.
Specifically, the customer views all bank card information under his own name through the ATM, can select one or more deducted bank cards, and inputs the withdrawal amount. The ATM judges whether the customer withdraws by crossing the bank, and if not, the ATM directly withdraws; if the customer withdraws from the bank, the withdrawal information of the customer sent by the ATM is received, whether the balance of the bank card for deduction selected by the customer is sufficient is judged, if so, transfer records are respectively sent to the bank card selected by the customer, and the selected banks respectively transfer corresponding amounts to the bank to which the ATM belongs. For example, the customer selects to draw 1K and 2K from the bank buckles of the line B and the line C through the ATM of the line a, the line B needs to transfer 1K to the public account of the line a, and the line C needs to transfer 2K to the public account of the line a (i.e., transfer is performed between banks first). And after the transfer is successful, receiving a transfer success message returned by the bank end.
After receiving the successful transfer message, the ATM is informed to normally withdraw money, and the ATM normally spits money to the customer.
After the withdrawal is successful, the customer account information stored in the blockchain is updated, mainly the balance is reduced, and the amount of money withdrawn by the customer is reduced.
The data acquisition, storage, use, processing and the like in the technical scheme all accord with the relevant regulations of national laws and regulations.
