In a post on the Ada Lovelace Institute blog, members of the PRIO project "Do No Harm: Ethical Humanitarian Innovation and Digital Bodies" Katja Lindskov Jacobsen and Belkis Wille look into how biometric data collection has caused harm in the context of humanitarian interventions and where the future risks lie. They find that in these specific settings, data protection policies and practices tend to be insufficient. Those already vulnerable from fleeing atrocities, wars or food insecurity are thus potentially exposed to further harm.
