How to opt-out secondary use of National Health Insurance Data? Massive Databases you might not Aware

Medical Privacy: Do You Care?

An introduction to opting out of data sharing, current limitations, and examples of the landscape of government databases in Taiwan.

Do you care about your medical privacy? For years, national health insurance data in Taiwan have been shared with industry and academia without consent. It is mandatory insurance, which means almost all the population in Taiwan have joined the system.

Following a series of "Right to Opt-Out" lawsuits spearheaded by three NGOs—the Taiwan Association for Human Rights (TAHR), Taiwan Women's Link, and the NHI Supervision Alliance—the secondary use of National Health Insurance (NHI) data has gradually shifted. Changes included halting the sale of data on physical discs and restricting access strictly to research purposes. In 2022, a landmark Constitutional Court ruling finally confirmed that the government must allow citizens to exercise their Right to Object (the right to stop the use of their data), ensuring individuals can refuse to have their personal information used for purposes other than their original intent. While Taiwan finally amended its laws last year to enable this right, several exceptions were added during the legislative process, significantly narrowing the actual scope of the "Right to Opt-Out."

Why This Matters

Beyond the NHI database, Taiwan maintains numerous other databases containing vast amounts of identifiable personal data. Many of these operate under vague legal frameworks with unclear protections for data subjects' rights. Now more than ever, these systems require vigilant oversight from civil society.
