Financial regulators face challenges in promoting information sharing within the industry due to data privacy compliance issues, particularly under GDPR, but Privacy-Enhancing Technologies (PETs) offer a solution by enabling secure data sharing without compromising privacy and regulatory compliance. During a discussion on Financial Intelligence Sharing under GDPR, experts highlighted successful implementations such as the DANIE consortium for Customer Due Diligence, Transaction Monitoring Netherlands for collective transaction monitoring, and the Cyber Defence Alliance for fraud investigations, all of which utilized PETs to enhance data protection and collaboration. These technologies help overcome regulatory uncertainties and compliance risks, allowing institutions to share encrypted insights, thus facilitating innovation in financial crime prevention. Despite regulatory grey areas, PETs minimize compliance risks, enhance machine learning applications, and promote efficient cross-border data sharing, suggesting a need for clearer regulatory guidance to further encourage such initiatives.
