Abstract

The invention provides a transparent online database anonymized data parallel migration method comprising the following step: (1) adding a flag bit field and a corresponding anonymized field to a table which is determined and needed to be anonymized; 2) renaming the table to be anonymized, creating a view with the same name as the table to be anonymized and making the name and the number of each field the same as the table to be anonymized; (3) creating insert / add, update / modify and delete / delete triggers for views with the same name; (4) cyclically obtaining the unmigrated data in small batches according to the unmigrated flag bits and anonymously updating the data needed to be anonymized into the table until all updates are completed; and (5) the business operation data of the application system of the corresponding table are added, deleted, modified and queried in real time according to the rows of the view. The method can solve the problem that the business information system needsto be shut down in the data migration process so as to realize the online type transparency of the data migration and service of the business information system.

Description

technical field [0001] The invention relates to a method for parallel migration of anonymized data in a transparent online database, belonging to the field of data security protection. Background technique [0002] With the gradual and in-depth application of informatization construction, various businesses have higher and higher requirements for real-time online business systems. At present, the anonymization protection of existing information data needs to stop the business and perform separate data migration to achieve data synchronization. consistency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transparent online database anonymized data parallel migration method to solve the need to shut down the business information system during the data migration process and achieve the data migration of the business information system. Online transparency with services. [0004] The technical solution adopted by...
