Health data privacy protections must extend beyond individuals, microbiome researchers argue
When a person consents to sharing their health data, they may inadvertently reveal sensitive information about the people with whom they interact. For example, someone who submits an oral swab for analysis could expose shared microbial signatures that provide information about others in their orbit, without those individuals' knowledge or consent. This is called a breach of relational privacy.
Researchers at Yale University are urging for the extension of health data privacy protections beyond individual consent to include the broader implications of microbiome data sharing. The human microbiome, which consists of microorganisms living on and within the body, can reflect not only an individual's health and physiology but also reveal sensitive information about their social interactions and the people they frequently encounter.
This phenomenon, known as relational privacy, arises when sharing one's microbiome data unintentionally exposes information about others in their network without their knowledge or consent. While advancements in biomedical and data science have made it easier to collect and analyze microbiome data, existing privacy frameworks primarily focus on individual privacy rather than the collective nature of this information.
This oversight leaves gaps in relational privacy protection, particularly when it comes to large-scale microbiome data sharing and its potential to uncover social interactions and health information about individuals who have not consented to data sharing. The researchers advocate for the development of collective data governance principles and stronger safeguards to address these gaps and ensure that the benefits of microbiome research are balanced with the need to protect relational privacy.
