Covid-19 has given rise to an enormous amount of data. Everything from satellite data and mobile data to big data are providing insights on how the virus is spreading and where vulnerable communities are located. Collaboration is essential for leveraging this data, and the pandemic has prompted an increase in data partnerships. However, many of these data collaborations are raising privacy and security concerns - there are at least 27 countries currently using data from cell phone companies to track entire populations for COVID-19 purposes, and we don’t know how long this will continue. The crisis has also underscored many of the barriers to collaboration, including the lengthy negotiation process for negotiating data sharing agreements (DSAs) and the lack of trust and accountability between parties that can arise. Establishing the right legal frameworks and policies for managing the data are key to overcoming these obstacles.
