Amazon has faced public outrage for providing cloud services to the U.S. government, including law enforcement agencies that conduct mass-raids and separate families at the southern border. Now, Amazon Web Services (AWS) has rolled out more terrifying features for its cloud-based facial recognition system—including the ability to detect fear.

“Amazon Rekognition provides a comprehensive set of face detection, analysis, and recognition features for image and video analysis,” a blog post announcing the new features reads. “Face analysis generates metadata about detected faces in the form of gender, age range, emotions,” and other attributes such as whether the subject is smiling.
