Oracle Data Redaction is a new feature in Oracle Database 12c that enables the protection of data shown to users in real time without requiring changes to applications. It applies redaction at query execution time, so the stored data remains unchanged. Redaction policies are defined that specify what data to redact for which users. The feature is useful but has some limitations, such as not preventing privileged users like DBAs from accessing protected data. It also incurs a small performance overhead for queries against tables with redaction policies.
