The only way to fight deepfakes is by making deepfakes

Deepfake detection companies like Reality Defender and Pindrop are using AI to combat AI-generated fake audio and video, creating a $5.5 billion industry. These firms primarily serve corporations facing industrial-scale fraud, where scammers use deepfakes to impersonate executives and steal hundreds of thousands of dollars per incident. The technology analyzes voice and video calls in real-time, though it struggles with quality versus speed tradeoffs and remains too expensive for consumer use, leaving individuals vulnerable to deepfake scams.
