As data de-identification becomes a critical responsibility for all enterprises, the enactment of the European Union’s General Data Protection Regulation (GDPR) in 2018—considered the strictest international data privacy law—has had a major impact on industries such as finance, aviation, and e-commerce. Prudential Life Insurance, a company with nearly 30 years of presence in Taiwan and a nine-time recipient of the Financial Supervisory Commission’s “Model Life Insurance Company” recognition, took note of Trinity’s widespread adoption in the financial sector. After careful evaluation and hands-on testing, Prudential selected Trinity ETL and Trinity Data Protection as core tools for internal data de-identification and governance.

In this project, Trinity first performed a comprehensive scan across source systems to detect personal data fields, using configurable matching rules. Based on these scan results and pre-defined masking/encryption policies, Trinity automatically applied protection to the identified fields. Sensitive data from source tables was masked or encrypted and written into designated working tables and log tables. All of this was handled via Trinity’s built-in automated scheduling system, which enabled seamless processing of daytime changes during operational windows and nighttime changes after batch jobs and backups were completed—without requiring manual intervention, even in complex database environments.

With diverse data sources across multiple database systems, Prudential relies on change logs to track all information movement. Trinity ETL and the Trinity Data Protection module allow the company to dynamically apply masking and encryption rules based on scan results and corporate data governance policies. This ensures that sensitive information is protected at every stage of its lifecycle, significantly reducing the risk of data leakage or regulatory non-compliance.
