How to Implement Privacy Enhancing Technologies (PETs)?

Organizations face increasing pressure to protect sensitive information while maintaining compliance. Privacy Enhancing Technologies (PETs) have emerged as a critical solution to achieve this balance. Leveraging PETs within a solid data risk management and governance strategy and data management framework helps companies protect user privacy, ensure ethical data use, and improve trust. As generative AI and analytics advance, ensuring data quality and security becomes essential to long-term success.

A Guide to Data Protection with Privacy Enhancing Technologies (PETs)

PETs refer to a set of tools and practices designed to minimize the exposure of personal data while still allowing valuable analysis. These technologies enable privacy by design, ensuring compliance with global regulations like GDPR and CCPA. They are used in both consumer-facing applications and enterprise-level analytics systems.

7 Essential Privacy Enhancing Technologies for Data Protection

1. Differential Privacy – Adds mathematical noise to datasets to prevent re-identification.

2. Homomorphic Encryption – Allows computations on encrypted data without decryption.

3. Secure Multi-Party Computation (SMPC) – Enables data analysis across sources without exposing raw data.

4. Federated Learning – Trains algorithms across decentralized devices without moving the data.

5. Synthetic Data Generation – Produces anonymized, artificial datasets with statistical value.

6. Data Masking – Hides specific data within a database to reduce exposure risk.

7. Zero-Knowledge Proofs – Validates a statement without revealing the underlying data.

How to Use PETs for Enhanced Privacy

To implement PETs effectively, companies must:

• Conduct a data protection risk assessment

• Classify data types based on sensitivity

• Integrate PETs into existing data governance and engineering frameworks

• Educate employees on data privacy best practices

• Regularly evaluate PET performance and regulatory compliance
