   Select Data Source	Select a data source. Only MRS_HIVE is available.
   Data Source NOTE: If no Hive database is available, click Add Database to add database assets. For details, see Authorizing Access to Big Data Assets.	Database instance: Select the database instance where the data you want to mask is located.
   	Database: Select the name of the database where the data you want to mask is located.

   1. Select the data columns you want to mask.
   2. Select a data masking algorithm. For details about data masking algorithms, see Configuring a Data Masking Rule.

8. Click Next to switch to the Configure Data Masking Period page and configure the data masking period.

   Select and set the execution period of a masking task.

   • Manual: Manually enable a masking task and execute it based on masking rules.
   • Hourly: Execute a data masking task every several hours.

     Example: If the masking task needs to be executed every two hours, set this parameter to 02:00.

   • Daily: Execute a data masking task at a specified time every day.

     Example: If the masking task needs to be executed at 12:00 every day, set this parameter to 12:00:00.

   • Weekly: Execute a data masking task at a specified time every week.

     Example: If the masking task needs to be executed at 12:00 every Monday, set this parameter to 12:00:00 every Monday.

   • Monthly: Execute a data masking task at a specified time on a specified day every month.

     Example: If the masking task needs to be executed at 12:00 on the 12th day of each month, set this parameter to 12:00:00 12th day of every month.

     

     If you want to execute a data masking task on the 31st day of each month, the system automatically executes the task on the last day of every month.

9. Click Next.
   Figure 2 Setting target data
   
   1. Select a database instance and database name, and enter the database table name.

      If the entered data table name already exists, the system updates the data table in the target database.

      If the entered data table name does not exist, the system automatically creates a data table with the same name in the target database.

      

      Do not fill in an existing service data table. Otherwise, services may be affected.

   2. Set the column name of the target data type.

      By default, the system generates a name that is the same as the name of the data source column. You can retain the default name or change it as required.

10. Click Finish.
11. Click the MRS tab. Locate the row containing the target data masking task and click Execute in the Operation column.
12. The data masking task is executed as configured.
