Researcher identification schemes (or author IDs) provide a unique identifier for each researcher. Having a distinctive author name is essential for academics’ work to be found among a global network of researchers.
ORCID (Open Researcher and Contributor ID) is a free nonproprietary alphanumeric code to uniquely identify authors and contributors of scholarly communication as well as ORCID's website and services to look up authors and their bibliographic output (and other user-supplied pieces of information).

Publons is an integrated space to manage researcher profiles, author identifiers, and peer review. Publons offers:
Via Web of Science:
Scopus automatically generates an author identifier for authors in the Scopus database and attempts to disambiguate authors and build an author profile. Citation metrics are included with each author profile. You cannot edit your author profile yourself, but you can request corrections if publications are incorrectly assigned (or missing from) your profile or you find other errors.
ISNI is the ISO certified global standard number (ISO 27729) for identifying the millions of contributors to creative works and those active in their distribution, including researchers, inventors, writers, artists, visual creators, performers, producers, publishers, aggregators, and is used to disambiguate contributor names to improve search and discovery. It is most commonly used in commercial publishing.
