1 Introduction to Oracle Data Redaction

Oracle Data Redaction enables you to redact data that is returned from queries issued by applications.

• What Is Oracle Data Redaction?
  Oracle Data Redaction enables you to obscure data that is returned from queries without affecting the data directly. This is done by redacting (selectively removing or obscuring sensitive or confidential information) the results of database queries just before presenting the results.
• When to Use Oracle Data Redaction
  Unlike data masking, which masks sensitive data by permanently replacing it with fictitious but realistic data, data redaction redacts data as it is received from the database, leaving the data in the database unchanged.
• Benefits of Using Oracle Data Redaction
  Oracle Data Redaction provides several benefits when you use it to protect your data.
• Example Use Cases for Oracle Data Redaction
  Oracle Data Redaction addresses common use case scenarios.
• Oracle Data Redaction in a Multitenant Environment
  Oracle Data Redaction policies are created and applied at the PDB level, and only apply to objects in that PDB. You cannot create redaction policies in the CDB root.
