ORCID MandateACM now requires that all
accepted journal authors register and provide ACM with valid ORCIDs prior to paper publication. Corresponding authors are responsible for collecting these ORCIDs from co-authors and providing them to ACM as part of the ACM eRights selection process.
You and your co-authors can create and register your ORCIDs at
https://orcid.org/register. ACM only requires you to complete the initial ORCID registration process. However, ACM encourages you to take the additional step to claim ownership of all of your published works via the ORCID site.
