Taipei Veterans General Hospital (TVGH), one of Taiwan’s leading medical centers, has long faced challenges managing the vast amounts of data generated across its various front-end information systems. All data is funneled into a central core database, making it difficult to normalize, organize, and manage efficiently. Historically, data extraction and handling have relied heavily on manual work or custom-developed programs by IT staff and researchers. The hospital lacked a unified tool or system to support consistent data integration, maintenance, and preservation.

Given the nature of healthcare data, the hospital stores a substantial volume of sensitive information that must be carefully protected and processed in accordance with Taiwan’s Personal Data Protection Act (PDPA). Beyond common practices like encryption and access control, it is essential that even authorized system operators, administrators, and developers follow strict protocols to mitigate the risk of data exposure.

To address these concerns, TVGH implemented Trinity ETL within its Health Information System. Beyond leveraging auditing systems to monitor user activity, the hospital used Trinity to conduct a comprehensive scan and inventory of sensitive data across all environments. Every field across existing databases was systematically reviewed, making all categories of sensitive and personally identifiable information (PII) fully visible and accounted for.

As part of the project, Trinity not only facilitated a centralized inventory of PII but also applied masking and obfuscation techniques in compliance with privacy regulations—ensuring that critical personal data remains protected from unauthorized exposure. Today, TVGH continues to expand its research data initiatives, aiming to further extend the use of Trinity into applications such as precision medicine, AI-driven analytics, and other advanced healthcare solutions.
