SECURITY SYSTEM USING THE DATA MASKING AND DATA SECURITY METHOD THEREOF

摘要

A security system using data masking is disclosed. A query processing module receives a query from at least one user terminal and then transmits it to a relevant DBMS. A found data checking module receives and checks found data from the DBMS. A basic data management module stores a masking policy for security data. A masking module compares the found data checked by the found data checking module with the masking policy of the basic data management module and then masks relevant data. A user identification module checks information about a user who has gained access through the user terminal and information about the security level of the user. A DBMS identification module is provided with one or more application programs which are compatible with respective DBMSs so that communication can be performed regardless of the types of DBMSs. A masking server transmits the masked data to the user terminal.
