Insight: The new EU–US data protection framework’s implications for h

=================================

Winners Consulting Services Co. Ltd. (積穗科研股份有限公司), Taiwan's expert in Privacy Information Management System (PIMS) consulting, alerts healthcare technology executives and compliance officers: a landmark 2024 academic study — cited 24 times since publication — reveals that the EU–US Data Privacy Framework (DPF), which took effect in July 2023, contains structural gaps that may render it insufficient for lawful health data transfers between the European Union and the United States. For Taiwanese enterprises seeking to partner with EU or US healthcare institutions, this finding demands an immediate reassessment of cross-border data transfer strategies, DPIA protocols, and ISO 27701 readiness.

About the Authors and the Research

This paper brings together three scholars at the forefront of privacy law, biomedical data governance, and life sciences regulation. Charlotte Tschider is a law professor at Loyola University Chicago School of Law, where she specializes in healthcare data privacy, AI regulation, and digital health policy. Her work occupies a distinctive niche at the intersection of US federal health law and emerging data protection frameworks, making her one of the most cited voices in American health privacy scholarship.

Marcelo Corrales Compagnucci focuses on data protection law and digital transformation across European and Latin American legal systems, contributing comparative legal perspectives that are rarely found in English-language data privacy literature. Timo Minssen holds a chair at the University of Copenhagen Faculty of Law and is among Europe's leading authorities on life sciences law, with particular expertise in biotechnology, health data governance, and intellectual property at the intersection of innovation and regulation.

Published in the Journal of Law and the Biosciences — one of Oxford University Press's flagship interdisciplinary journals — this paper has accumulated 24 academic citations since its 2024 publication, reflecting rapid uptake in both legal and health policy communities. The tri-continental authorship (US, continental Europe, and Nordic) gives the paper unusual analytical depth in comparing transatlantic regulatory systems.

Three Structural Gaps in the DPF That Threaten Lawful Health Data Transfers

The core contribution of this research is not simply documenting what the DPF does — it is demonstrating where the DPF falls short, specifically when applied to the sensitive and legally complex domain of health and medical research data. The authors identify three structural inadequacies that enterprises relying solely on the DPF will find difficult to overcome.

Finding One: The EU Member State Fragmentation Problem

Article 9 of the GDPR classifies health data as a "special category" and explicitly permits EU Member States to impose additional, more restrictive conditions beyond the baseline GDPR requirements. The research demonstrates that the DPF was designed primarily with reference to the GDPR's federal-level adequacy criteria, without adequately accounting for the divergent national health data regulations across all 27 EU Member States. An organization certified under the DPF may be fully compliant at the EU level yet simultaneously non-compliant with the health data laws of Germany, France, Ireland, or any other individual Member State. This fragmentation risk is not hypothetical — it represents a real legal liability for any enterprise conducting health data transfers into or out of specific EU jurisdictions.

Finding Two: The Fundamental HIPAA–GDPR Institutional Mismatch

The United States has long governed healthcare data through the Health Insurance Portability and Accountability Act (HIPAA), a sectoral law focused on specific covered entities and their business associates. The GDPR operates on fundamentally different principles, including broader definitions of personal data, stronger data subject rights (access, erasure, portability), stricter purpose limitation and data minimization requirements, and more expansive territorial scope. The study finds that the DPF does not meaningfully bridge this institutional gap. US healthcare organizations relying on DPF certification may believe they have addressed EU adequacy concerns, when in reality their HIPAA-compliant practices may still fall short of GDPR's expectations for health data processing. This creates a false sense of compliance security that is particularly dangerous for organizations handling patient data across transatlantic borders.

Finding Three: Alternative Transfer Mechanisms Offer Greater Legal Certainty

After systematically evaluating the DPF against other GDPR-recognized cross-border transfer tools, the research team concludes that Standard Contractual Clauses (SCCs) under Article 46, Binding Corporate Rules (BCRs), and other supplementary safeguards under Article 46(2) provide measurably greater predictability and legal certainty for health data transfers than the DPF. This is a significant strategic finding: for healthcare entities and health technology companies considering their cross-border data transfer architecture, the DPF should not be the first or only instrument considered. In many scenarios, SCCs combined with robust technical and organizational measures — and documented through a comprehensive DPIA — will offer a more defensible compliance posture.

What This Research Means for Taiwan Enterprises Managing Cross-Border Health and Business Data

Taiwan's enterprises — particularly those in the health technology, biomedical, semiconductor, and professional services sectors — increasingly seek to establish data-sharing relationships with European and American institutions. This research delivers three important signals for Taiwan's Privacy Information Management (PIMS) practitioners.

First, the Taiwan Personal Data Protection Act (個人資料保護法, hereinafter "Taiwan PDPA") has not yet received EU adequacy recognition, meaning that Taiwanese companies receiving EU personal data must currently rely on SCCs or other Article 46 mechanisms as the legal basis for transfer. The DPF's inadequacies in the health data domain underscore the importance of Taiwan enterprises understanding which transfer mechanism applies to them and building compliance systems accordingly — rather than assuming any single framework is universally sufficient.

Second, ISO 27701 — the international standard for Privacy Information Management Systems — provides a structured framework that maps directly onto both GDPR compliance requirements (including Article 5 processing principles, Article 25 Privacy by Design, Article 32 security measures, and Article 35 DPIA requirements) and the security maintenance obligations under Article 27 of the Taiwan PDPA. Achieving ISO 27701 certification is increasingly recognized by EU supervisory authorities as credible evidence of an organization's commitment to privacy-compliant data processing.

Third, the research's emphasis on DPIA as a critical tool for evaluating health data transfer risks aligns with best practices in ISO 27701 implementation. Taiwan enterprises that have not yet integrated DPIA into their standard operating procedures for cross-border data transfers are operating with a significant compliance blind spot — one that this research makes impossible to ignore.

How Winners Consulting Services Co. Ltd. Helps Taiwan Enterprises Build Compliant Cross-Border Data Governance

積穗科研股份有限公司（Winners Consulting Services Co. Ltd.）provides end-to-end consulting services for Privacy Information Management System (PIMS) implementation, ISO 27701 certification, GDPR compliance assessment, DPIA execution, and Taiwan PDPA alignment. In response to the cross-border health data compliance challenges identified in this research, we recommend the following specific actions:

1. Cross-Border Data Transfer Compliance Audit: Systematically map all existing cross-border data flows within your organization, with special attention to flows involving health data, biometric data, or other GDPR special category data. Evaluate whether current transfer mechanisms (DPF, SCCs, BCRs, or others) are appropriate for each data flow and jurisdiction pair, and identify gaps requiring remediation. This audit should produce a documented transfer mechanism register that can withstand regulatory scrutiny.
2. DPIA Execution for Health Data Transfer Scenarios: For any enterprise handling health-related data in cross-border contexts, commission a customized Data Protection Impact Assessment (DPIA) in accordance with GDPR Article 35 and ISO 27701 Annex requirements. The DPIA should specifically address the Member State fragmentation risk identified in the research — assessing not only EU-level GDPR compliance but also the additional requirements of each target Member State jurisdiction. Complete DPIA documentation, including risk registers, mitigation measures, and review schedules, should be maintained as part of the enterprise's accountability record.
3. ISO 27701 Implementation and Certification Roadmap: Engage a structured ISO 27701 implementation program, beginning with a Gap Analysis to identify current shortfalls against the standard's requirements, followed by policy and procedure development, staff training, internal audit, and third-party certification application. For enterprises already holding ISO 27001 certification, the additional effort required for ISO 27701 is substantially reduced, as the two standards share an integrated architecture. Winners Consulting offers an accelerated 90-day program to establish the foundational PIMS structure required for certification readiness.

Frequently Asked Questions

Is the EU–US Data Privacy Framework (DPF) sufficient for Taiwanese healthcare companies to legally transfer patient data to EU partners?

No — and for most Taiwanese enterprises, the DPF is not even directly applicable. The DPF is a self-certification mechanism designed specifically for US-based organizations. Taiwanese companies receiving EU personal data must rely on GDPR Article 46 mechanisms such as Standard Contractual Clauses (SCCs). Even for US organizations, the 2024 research published in the Journal of Law and the Biosciences (cited 24 times) finds that the DPF contains structural gaps for health data scenarios — particularly the inability to preemptively address individual EU Member State health data requirements that exceed GDPR's baseline. Taiwan enterprises should work with qualified PIMS consultants to identify appropriate transfer mechanisms for each specific cross-border data flow.

What are the most commonly overlooked GDPR compliance risks for Taiwanese companies engaging European business partners?

The most frequently overlooked risk is Member State legal divergence. Many Taiwanese enterprises assume that GDPR compliance provides a single, unified pass for all 27 EU Member States — but this is incorrect. Each Member State may enact additional restrictions on special category data (including health data, genetic data, and biometric data), and
