Certificates of Confidentiality (CoC) - Human Subjects
Certificates of Confidentiality (CoCs) protect the privacy of research subjects by prohibiting disclosure of identifiable, sensitive research information to anyone not connected to the research except when the subject consents or in a few other specific situations. Learn about the NIH Policy for issuing CoCs, its purpose, scope and applicability, disclosure requirements, and responsibilities of CoC recipients.
CoCs are issued automatically for any NIH-funded projects using identifiable, sensitive information. Learn more about eligibility for receiving a CoC for research that is funded by other HHS-agencies, by non-HHS federal agencies, and for research supported by non-federal funders.
NIH uses an online system for CoC requests for non-NIH funded research. Learn how to access the NIH online CoC system through this page, and the type of information required before you submit your CoC request. Find information about extending or amending an existing CoC.
