Facial Recognition in War Contexts: Mass Surveillance and Mass Atrocity

The use of facial recognition technology (FRT) as a form of intelligence has recently made a prominent public appearance in the theater of war. During the early months of Russia's invasion of Ukraine, Ukrainian authorities relied on FRT as part of the country's defensive activities, harnessing the technology for a variety of purposes, such as unveiling covert Russian agents operating amid the Ukrainian population; revealing the identity of Russian soldiers who committed war crimes; and even identifying dead Russian soldiers. This constellation of uses of FRT-in a war increasingly waged on the digital and information front-warrants ethical examination. The essay discusses some of the most serious concerns with FRT in the context of war, including the infringement of informational privacy; the indiscriminate and disproportionate harms it may inflict, particularly when the technology is coupled with social media intelligence; and the potential abuse of the technology once the fog of war dissipates. Some of these concerns parallel those to be found in nations that are not engulfed in war, but others are unique to war-torn settings.
