A planning committee of the National Academies of Sciences, Engineering and Medicine will organize a virtual workshop to examine the collection, interpretation, and use of location data by the government, academia and industry. The workshop will focus on how, and for what purposes, location data can be used in public health, research, and law enforcement. It will also address ethical issues associated with the collection and use of location data. It will examine the regulatory and governance frameworks governing the use, collection, and aggregation of such data both in the United States and globally (with particular attention to data protection and privacy), explore gaps in the current governance framework, and discuss potential mechanisms for enhancing data privacy protections and limiting, as appropriate, the use and sharing of data from the public health context. A proceedings in brief will be issued following the workshop.
