Explanation:
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. References:
