 Anonymity has value in a variety of public health and medical research contexts. Research publications commonly shield the identities of biomedical research subjects or clinical patients. Special attention is paid to genetic information. Although a number of prominent scientists and lay people have made their genomes public, genetics research and scholarly publication standards call for protection of the identities of research subjects and their families. Bioethicists distinguish between identifiable, de-identified and anonymized whole genome sequencing data. (Presidential Commission, 2012) In the US, de-identified data is not protected under the laws protecting human subjects known as the Common Rule. Concerns can arise about whether particular methods of de-identification and anonymization adequately shield individuals from invasion of privacy and breaches of confidentiality (Yoo et al. 2018). “Differential privacy” is an anonymization approach to personal data sharing favored by some computer scientists that has potential value to health care data (Dwork 2006).
