Pseudonymization

Pseudonymization is a data processing technique that reduces the risks associated with personal data. As defined in Article 4(5) of the EU's General Data Protection Regulation (GDPR), it is the processing of personal data in such a manner that it can no longer be attributed to a specific data subject without the use of "additional information." This "additional information" must be kept separately and be subject to technical and organizational measures to ensure non-attribution.

With the tightening of Taiwan's Personal Data Protection Act and stricter international supply chain requirements, companies face significant fines and class-action lawsuits if they fail to protect customer and employee data. For industries like semiconductors and automotive supply chains dealing with EU/US clients, implementing measures like pseudonymization to comply with GDPR is not just a legal obligation but crucial for retaining orders and market trust.

Pseudonymization is closely linked to several international standards and regulations: - **EU GDPR**: Article 25 (Data protection by design and by default) and Article 32 (Security of processing) explicitly encourage its use as a technical safeguard. - **ISO/IEC 27701 (Privacy Information Management System)**: As an extension to ISO 27001, this standard provides a framework for privacy protection, where pseudonymization is a key technique to meet PII protection objectives. - **ISO/IEC 27018 (Code of practice for PII protection in public clouds)**: Also references similar de-identification techniques to protect personal data in cloud environments.
