Questions & Answers

What is Anonymization?

Anonymization is the process of irreversibly altering personal data so that a specific individual can no longer be identified. According to Recital 26 of the EU's General Data Protection Regulation (GDPR), anonymized data is not considered personal data and is therefore not subject to its regulations. This concept aligns with de-identification, where data is processed to prevent identification of the data subject.

Why is it important for Taiwanese companies?

Taiwan's Personal Data Protection Act (PDPA) can impose fines of up to NT$15 million for data breaches. To enter the EU market, companies must comply with the strict GDPR, which carries fines of up to 4% of global annual turnover. Proper anonymization is not just a legal obligation but is crucial for protecting business reputation and maintaining trust with customers and supply chain partners, especially in sensitive industries like semiconductors and healthcare.

Which ISO standards or international regulations are directly related?

The primary standard is **ISO/IEC 27701 (Privacy Information Management System)**, which provides guidance on privacy protection controls like data minimization and de-identification techniques. This standard builds upon **ISO/IEC 27001 (Information Security Management System)**. In terms of international law, **Recital 26 of the EU's GDPR** explicitly defines the concept and legal effect of anonymization, serving as a key global benchmark.
