Given the sensitivity of PII, stringent measures are put in place to protect it:
1. Data Encryption: Encrypting data ensures that even if it is intercepted, it cannot be read without the decryption key. 2. Access Controls: Only authorized personnel should have access to PII. This is often managed through role-based access controls. 3. Data Anonymization: Transforming PII into anonymous data where individual identifiers are removed or masked, making it impossible to trace back to the individual. 4. Legal Compliance: Adhering to laws and regulations such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States, which sets standards for protecting health information.
