Data Sharing and Privacy Protection

lableing sample

The promises and perils of the digital age are apparent in every aspect of online information, and scientific research data is no exception. The ability to share widely the digital data from personal exposures to toxics found in blood, urine or household air and dust helps promote collaboration and discovery and also prevents the need to repeat collection of the same data for each separate study – a process that takes precious research dollars and, in some cases, is not possible. At the same time, online sharing of personal data raises new concerns about the possibility that the identity of study participants might be revealed (a process called “re-identification”) even in data considered anonymized, exposing participants to discrimination or other risks.

As scientists committed to collaboration, we addressed the growing need for an ethics of data sharing and privacy protection as we know best – through research. With funding from the National Institutes of Health and in partnership with Harvard’s Digital Privacy Lab and Northeastern’s Social Science and Environmental Health Research Institute, Silent Spring Institute is currently investigating privacy risks in environmental health studies. We will develop a model to predict the probability of re-identification and design technical strategies to fix vulnerabilities. Results from this project – the first of its kind – will provide researchers with ethically and technically sound methods for sharing environmental data, making the discovery of preventable causes of disease easier and safer.
