Masking
Mask sensitive field values while retaining the formatting criteria
Objective
A technique commonly used by dynamic data masking within the RDBMS.
On-the-fly data obfuscation rules are executed on the source data event to enable PII data.
Certain fields are replaced with a mask character (such as an ‘XXX’). This removes the actual content while preserving the same formatting.
Example
Masks credit card details while preserving the pattern.
