When to Use Oracle Data Redaction

1.2 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.

Data Redaction enables you to easily disguise the data using several different redaction styles.

Oracle Data Redaction is particularly suited for call center applications, ad hoc reporting, and analytic workloads where the data is only available to the end user in a read-only format. However, take care when using Oracle Data Redaction with applications that perform updates back to the database because redacted data can be written back to this database.

For example, you may wish to redact:

U.S. Social Security Numbers to only display the last four digits.
American Express credit card numbers to only the last five digits.
Fully redact salary, marital status, or medical data from views.
Only certain columns in an analytic query, where the end user needs to see summaries of data but not actual values.
