Customs declaration data processing method and device, computer equipment and storage medium

Abstract

The invention relates to the field of big data processing, in particular to a customs declaration data processing method and device, computer equipment and a storage medium. The method comprises the following steps: receiving customs declaration data sent by a declaration main body, wherein the customs declaration data carries an order identifier, a payment order identifier and a waybill identifier; obtaining encrypted order data, encrypted payment order data and encrypted waybill data from corresponding nodes of the block chain according to the order identifier, the payment order identifier and the waybill identifier; obtaining a directionally authorized decryption key corresponding to the encrypted order data, the encrypted payment bill data and the encrypted waybill data; decrypting thecorresponding data through the obtained decryption key of the directional authorization; performing cross validation on the decrypted order data, payment data and waybill data to obtain a cross validation result; and when the cross validation result shows that the order data, the payment order data and the waybill data are inconsistent, increasing the check rate of customs clearance articles corresponding to the customs clearance data. By adopting the method, the data security can be ensured.

Description

technical field [0001] The present application relates to the technical field of big data processing, in particular to a customs declaration data processing method, device, computer equipment and storage medium. Background technique [0002] At present, the mode of electronic customs declaration is mostly used to process the customs declaration data, and the mode of "three bills matching" is introduced to review the customs declaration data, in which the three bills refer to the order, payment bill and waybill respectively. However, there is the possibility of data tampering in the data of the three orders, and its authenticity and security cannot be guaranteed, which leads to the fact that the data in the three-order match is not true. Contents of the invention [0003] Based on this, it is necessary to address the above technical problems and provide a customs declaration data processing method, device, computer equipment and storage medium capable of ensuring data secur...
