Introduction

As organizations collect and process vast amounts of personal data, ensuring privacy and security is paramount. Data anonymization and pseudonymization are two key techniques that help organizations protect sensitive information while still making it usable for analysis and research. These techniques are essential for compliance with regulations such as GDPR, which requires that personal data be handled in ways that preserve privacy. This course will provide both theoretical knowledge and practical skills for implementing data anonymization and pseudonymization strategies in data management systems.

Objectives

By the end of this course, participants will be able to:

• Understand the principles and regulatory requirements surrounding data anonymization and pseudonymization.
• Differentiate between anonymization and pseudonymization, and when to use each technique.
• Learn how to implement various data anonymization techniques (e.g., generalization, suppression, data perturbation).
• Understand and apply pseudonymization techniques, including tokenization and encryption.
• Explore the advantages and limitations of these techniques for data privacy and security.
• Integrate anonymization and pseudonymization into data workflows while ensuring compliance with data protection laws (e.g., GDPR).
• Assess the effectiveness of anonymization and pseudonymization in different use cases.
