The increasing interconnectedness and reusability of scientific data have brought forth unparalleled challenges in the realm of international science and technology(S&T)cooperation.Against the backdrop of a dynamic and intricate international landscape,the rapid evolution of information technology has accentuated the salience of security concerns surrounding scientific data,thereby imposing significant challenges upon extant security frameworks.This paper,following a meticulous elucidation of the concept of scientific data safety,systematically consolidates governance policies and practices pertaining to scientific data sharing gleaned from prominent international S&T organizations and major international S&T initiatives.Four discerning recommendations are delineated:(1)Advocating the principle of"openness as the norm,with exceptions,"by discerningly deploying"exceptions"and"exemption lists"to strike a harmonious balance between obligations and rights;(2)Continuously enhancing the domestic governance policy ecosystem for scientific data security,thereby fostering transparency and compliance with scientific data policies within the ambit of international S&T collaborations;(3)Adopting a comprehensive approach that duly considers factors such as scientific data resources and risk control technologies,to facilitate genuine peer-to-peer scientific data exchanges;(4)Instituting a proficient data safety team adept in international policies,regulations,and best practices,and fortified with a robust array of technical competencies.
