Control of the access to your own data is a fundamental principle of ORCID: "Researchers control the defined visibility settings of their own ORCID record data."
You can change the visibility settings for all items on your ORCID record. Only one item always remains visible to everyone: your ORCID iD.
ORCID provides you three settings to control the visibility of your data:
Information marked as everyone can be viewed by anyone who comes to the orcid.org website or viewed by anyone using the ORCID public API. Data marked as visible to everyone will also be included in the public data file posted annually by ORCID.
Information marked as trusted parties can be seen by any trusted organizations that you have authorized to connect to your ORCID record. These connections require explicit action on your part. You will be asked if you would like to make a specific connection, and once you have confirmed, the trusted party will be able to see information that you have marked as trusted party access in addition to the information marked everyone. See trusted organizations for more information
Information marked as only me can only be seen by you and the trusted individuals you grant access to help administer your ORCID record. It is also used by ORCID algorithms to help distinguish your identity from another person who may have a similar name, be in a similar field, or may be confused with you for other reasons. This information is not shared with others.
