An Introduction To Data Masking In Privacy Engineering
Tripwire, Monday, March 24th, 2025
Protecting individual privacy is paramount, given the proliferation of Personally Identifiable Information (PII) and other sensitive data collected by enterprises across all industries.
One way to protect sensitive data is through PII masking e.g., consistently changing names or including only the last four digits of a credit card or Social Security Number.
What is data masking?
Data masking replaces sensitive columns in the source data with realistic test data. A data breach remediation strategy is primarily used to address areas of risk. By preserving the integrity and usability of the original, it creates an unidentifiable and secure version.
