Redacting Sensitive Data for Display

Data Redaction provides selective, on-the-fly redaction of sensitive data in query results prior

to display by applications so that unauthorized users cannot view the sensitive data. It enables

consistent redaction of database columns across application modules accessing the same data.

Data Redaction minimizes changes to applications because it does not alter actual data in

internal database buffers, caches, or storage, and it preserves the original data type and

formatting when transformed data is returned to the application. Data Redaction has no

impact on database operational activities such as backup and restore, upgrade and patch, and

high availability clusters.
