Ellie Daw

Abstract: Various privacy-preserving protocols for exposure notification have been developed across the globe in order to aid in scaling contact tracing efforts during the COVID-19 crisis, a strategy proven to be critical in effectively slowing the spread of infectious disease. Although having a multitude of people working toward a similar goal creates momentum and aids in quality refinement, it also causes confusion for entities hoping to adopt one protocol for application development. This paper compares the protocols component-by-component, accumulating in a comprehensive comparison table so that entities are able to take action based on their priorities.
