Abstract

The invention provides a hash-based account checking method and device, and relates to the technical field of big data. The Hash-based account checking method comprises the following steps: acquiring transaction data to be checked; calculating a hash value corresponding to each piece of transaction data in the transaction data, and generating leaf nodes of a Merkel tree based on the hash values; generating a plurality of reconciliation files according to leaf nodes of the Merkel tree; and performing checking based on a plurality of reconciliation files respectively generated by an upstream system and a downstream system. According to the method, the transaction data are converted into the hash value through hash calculation, the transaction data of any length are effectively reduced to be of a fixed size, and the difficulty degree of data checking is reduced; by generating the Merkel tree and the multiple reconciliation files, the amount of data needing to be checked is effectively reduced, and the reconciliation efficiency is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of big data, in particular to a hash-based reconciliation method and device. Background technique

[0002] With the rapid development of banking business, the transaction volume and data volume of the banking system are increasing by leaps and bounds. At the same time, the transaction process and business functions are separated, and the banking system is constantly and carefully divided into many business subsystems. Therefore, there will be many sub-service systems involved in a transaction process. In order to improve performance, the banking system relies more and more on distributed system technology, which leads to a large number of scenarios in the banking system that need to check the consistency of upstream and downstream data, and the system resources consumed for reconciliation also continue to increase. At present, the methods generally used are as follows: the downstream system generates a full...
