Data Masking and Anonymization: Protecting Sensitive Information

Organizations often handle large amounts of personally identifiable information (PII) and must ensure it is protected when shared or processed. Data masking and anonymization are techniques used to protect sensitive data while maintaining its usability.

Data Masking vs. Anonymization:

Data Masking: Replaces sensitive data with fictional but realistic values to prevent unauthorized access (e.g., masking credit card numbers as “XXXX-XXXX-XXXX-1234”).

Data Anonymization: Removes or alters personally identifiable information so it cannot be traced back to an individual (used in healthcare, research, and analytics).

These techniques allow businesses to use data for testing, analysis, and reporting while ensuring that privacy regulations like GDPR and CCPA are met. Implementing data masking and anonymization helps organizations reduce the risk of data exposure while maintaining functionality.
