At least 42 law enforcement agencies in Minnesota reportedly used Clearview AI facial recognition software, according to a Buzzfeed investigation. Questions about the softwares reliability and legal standing remain in limbo, according to law enforcement, artificial intelligence, and privacy experts. Clearview AI is a web-based platform that allows users to submit pictures for possible matches in a database of more than 3 billion images pulled from open source websites, including news sites and social media, according to the company's web page. The company also boasted of a 100% accuracy rate at one point, according to a document obtained by a public records request from Buzzfeed. However, questions about the software's reliability and legal standing remain in limbo, according to law enforcement and artificial intelligence and privacy experts.
