“In public health, we can’t do anything without surveillance. That’s where public health begins.”
-David Satcher, MD, PhD, U.S. Surgeon General, 1998-2002
Media outlets reported this week that representatives from Facebook, Google, Amazon, and Apple are meeting with members of the White House to brainstorm about ways in which the “Big Four”, can leverage the consumer information they possess to help in the war against COVID–19. Specifically, the government proposes to combine artificial intelligence with geolocation data collected from consumers’ smartphones and other devices to track the movement of individuals. Having knowledge about a population’s movement can help predict the future spread of the virus as well as pinpoint locations where an outbreak might be most severe.
The collaboration with these companies is noteworthy given the increasing and often hostile scrutiny by Congress and privacy advocates who demand increased oversight of the information giants. However, this is an unprecedented time of (hopefully temporary) self-isolation, plummeting financial markets, decimation of industries, shuttering of small businesses, and exacerbated food insecurity for the poor.
The value of cell-phone data in tracking, predicting, and understanding disease has been studied by various academics. In 2015, researchers from Harvard University and Princeton University published a study (Princeton University, Woodrow Wilson School of Public and International Affairs, 2015) in which cellphone data for more than 15 million users in Kenya was evaluated to determine whether movement around the country could predict the seasonal spread of rubella.
Interestingly, in November of 2019, just before news of the COVID-19 contagion broke, researchers from the Massachusetts Institute of Technology and the Ecole Polytechnique Federale de Lausanne published a paper in Scientific Reports regarding a study that demonstrated the relationship between human mobility and the 2013 and 2014 dengue outbreaks in Singapore. (Ecole Polytechnique Federale de Lausanne, 2019) Not surprisingly, the study revealed that human mobility is a significant variable in the spread of diseases such as malaria and dengue. In conducting the study, researchers used datasets that included anonymized mobile phone location data. The researchers ultimately called for legislation that would allow scientists, NGOs, and government to access consumer’s phone location data for public health purposes.
What would be the harm in allowing the government to gain access to mobile phone usage data? Will consumers receive notice if their cell phone usage data is disclosed to government or public health providers? How will a definitive connection be made between the activity associated with a given mobile phone and a specific individual? Do we feel comfortable with the disclosure and use of aggregated and anonymized geolocation data if it could provide valuable insight for disease mapping, resource allocation, and education purposes? Or, is the very real risk of reidentification too great? Can we ensure that the information shared will be limited to that of geolocation data or might the government gain access browsing history, app usage, photographs, etc.?
Disclosure of private personal information for use in the realm of public health and safety is not a novel concept. In fact, there exist today laws that attempt to codify a balance between consumer privacy and public health:
The laws referenced above speak to information pertaining to an individual’s health, not to information that, on its face, seems wholly unrelated to the safety and welfare of individuals. Is there a meaningful difference between the disclosure of such health-related information and information pertaining to mobile phone usage that will be used in the context of a public health crisis? Perhaps, is that a distinction without a difference given the urgency of the current situation.
Protecting society from public health threats is paramount, however, the privacy issues put forth by concerned individuals require thoughtful consideration. How will the data that is collected be used once the crisis ends? Will data collection cease at some point in time or continue indefinitely? Can we trust that public officials will appropriately govern access to and use of mobile phone data in a way that effectively balances consumer privacy with public health? Should consumer privacy carry equal weight in the face of a global quarantine and economic collapse? It will be interesting to see both the immediate results of the conversations between the White House and the Big 4 and the long-term impact on data privacy.
