ORCID strives to enable transparent and trustworthy connections between researchers, their contributions, and their affiliations by providing a unique, persistent identifier for individuals to use as they engage in research, scholarship, and innovation activities. Ensuring that the correct ORCID iD is associated with the right researcher is a critical step in building the trustworthiness of the ORCID dataset and the broader scholarly communications ecosystem. For this reason, ORCID does not permit the manual collection or entry of ORCID IDs in any workflow where it is possible to collect ORCID IDs directly from record holders themselves.
Researchers can easily and securely share their ORCID iDs with the systems they interact with, which proves they own their ORCID iD. Those systems can then share information about researcher activities with other systems, which creates a chain of validated and trusted assertions about researcher activity. The end result is that the correct person is associated with the correct activities across a broad range of scholarly information workflows.
