   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. On the Configure Data Masking Period page that is displayed, configure the 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.

   1. Select the database instance, namespace, and data table name, and enter the column family.

      If the entered column name already exists, the system updates the data in the column.

      If the entered column name does not exist, the system automatically creates the column in the target data table.

      

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

10. Click Finish.
11. On the HBase page. In the Operation column of the target anonymization task, click Execute.
12. The data masking task is executed as configured.
