Persistent Identifiers (PIDs) play a vital role in enhancing research security by enabling transparent, accurate, and interoperable tracking of research activities, affiliations, funding, and outputs. This presentation will explore how PIDs—such as ORCID iDs for researchers, ROR IDs for institutions, DOIs for publications and datasets, and grant identifiers—can help uncover risks related to undisclosed foreign affiliations, collaborations, and misattributed funding. PIDs support automated data validation, improving the integrity of researcher profiles, and facilitating cross-system compliance checks. PIDs are becoming essential tools for institutions and funding agencies to uphold the security and trustworthiness of the research ecosystem. In this session, we will explain the different persistent identifiers used in research, how they are used, and the level of adoption of PIDs worldwide. We will focus on the impact they have on research security workflows.
