| Aspect | Data Anonymization | Data Masking |
|---|
| Purpose | To permanently remove or alter identifiable information to protect privacy | To temporarily hide sensitive data for testing or training |
| Method | Data is irreversibly transformed | Data is reversibly masked or obscured |
| Use Cases | Data sharing, privacy compliance, anonymized analytics | Testing, development, user training |
| Impact on Data | Data becomes non-identifiable and unusable for original purposes | Data remains usable but obscured |
While both Data Anonymization and Data Masking aim to protect sensitive information, Data Anonymization permanently alters data to prevent re-identification, making it suitable for privacy compliance and sharing. Data Masking temporarily obscures data for testing or training, allowing data usability while protecting sensitive details.
