DYNAMIC DATA MASKING METHOD AND DATABASE SYSTEM

摘要

A dynamic data masking method, suitable for a database including plural data, is disclosed in this invention. Each of the data includes plural values and plural keys corresponding to the values. The dynamic data masking method includes steps of: determining whether values and keys of one data are sensitive contents when the data are requested to be written into the database; if one of the values/keys of the data is sensitive, setting a key corresponding to the sensitive value or the key itself as a sensitive key and dynamically establishing a filtering rule corresponding to the key; and then, saving the filtering rule and writing the data into the database. In addition, a database system is also disclosed herein.
