Scopus author profiles are created automatically when two or more articles are linked to the same author. The details are derived from their articles which are index in Scopus and these include: the author name, affiliation(s), subject area(s), publications, citations, and co-authors.
ORCiD, which stands for Open Researcher and Contributor iD provides a persistent digital identifier for the researcher (an ORCID iD) that they own and control, and that distinguishes them from every other researcher. This ID can be linked with their professional information — affiliations, grants, publications, peer review, and more. It can further be used to share the researcher's information with other systems, ensuring they get recognition for all their contributions.
It is important for researchers to use their ORCiD when requested, in systems and platforms from grant application to manuscript submission and beyond, in order to get credit for their contributions.
