Tarini Padmanabhuni’s grandfather was fooled by a deepfake claiming his brother had been kidnapped and held for ransom. Now her job is to prevent others from falling victim to the same scam. She founded DetectifAI to develop technology that detects deepfake voices. The market for deepfake voice detection is crowded, but they’re all cloud based AI models that don’t protect users. DetectifAI’s model is small enough to run on a smartphone, detecting fake calls without the user’s data leaving the device. Padmanabhuni is selling the model to phone manufacturers, so deepfake detection will be a built-in feature of operating systems going forward
