Contact-tracing apps are not a solution to the COVID-19 crisis

By Ryan Calo on

The unprecedented threat from the novel coronavirus has confined many Americans to their homes, distancing them from one another at great cost to local economies and personal well-being. Meanwhile the pressure grows on American institutions to do something—anything—about the pandemic.

Encouraged by the White House, much of that pressure to act has focused on Silicon Valley and the tech industry, which has responded with a fragile digital solution. Tech companies and engineering departments at major universities are pinning their hopes of returning Americans to work and play on the promise of smartphone apps. Coronavirus? There’s an app for that.

We are concerned by this rising enthusiasm for automated technology as a centerpiece of infection control. Between us, we hold extensive expertise in technology, law and policy, and epidemiology. We have serious doubts that voluntary, anonymous contact tracing through smartphone apps—as Apple, Google, and faculty at a number of academic institutions all propose—can free Americans of the terrible choice between staying home or risking exposure. We worry that contact-tracing apps will serve as vehicles for abuse and disinformation, while providing a false sense of security to justify reopening local and national economies well before it is safe to do so. Our recommendations are aimed at reducing the harm of a technological intervention that seems increasingly inevitable.

We have no doubts that the developers of contact-tracing apps and related technologies are well-intentioned. But we urge the developers of these systems to step up and acknowledge the limitations of those technologies before they are widely adopted. Health agencies and policymakers should not over-rely on these apps and, regardless, should make clear rules to head off the threat to privacy, equity, and liberty by imposing appropriate safeguards.
