The need to regulate face recognition technology use is one of the most pressing legislative issues facing governments today. Existing and proposed measures demonstrate the wide range of available approaches to regulation, including absolute bans, carefully-crafted restrictions, and ongoing democratic accountability measures. With this resource, we have aimed to provide a foundational understanding of these approaches. Our hope is that with this information in hand, legislators and the broader public will be empowered to pursue regulatory options that are responsive to the needs of their communities and that sufficiently account for the potentially significant privacy and civil rights implications of FRT use.
