19 Masking Sensitive Data

This chapter provides conceptual information about the components that comprise Oracle Data Masking, and procedural information about performing the task sequence, such as creating masking formats and masking definitions. Data masking presupposes that you have created an Application Data Model (ADM) with defined sensitive columns.

Topics discussed in this chapter include:

• Overview of Oracle Data Masking

• Format Libraries and Masking Definitions

• Recommended Data Masking Workflow

• Data Masking Task Sequence

• Defining Masking Formats

• Masking with an Application Data Model and Workloads

• Masking a Test System to Evaluate Performance

• Upgrade Considerations

• Using the Shuffle Format

• Using Group Shuffle

• Using Conditional Masking

• Using Data Masking with LONG Columns

The procedures in this chapter are applicable to Oracle Enterprise Manager 12.1 and higher Cloud Control only. You must have the Oracle Data Masking and Subsetting Pack license to use data masking features.
