Civil Liberties of AI Video Analysis, A Mental Trespass?
Imagine an app on your phone or computer that can tell if you are being dishonest, just by processing affective features of your facial expressions, body movements, and voice. People could ask about your political preferences, your sexual orientation, and immediately determine which of your responses are honest and which are not. In this study, we investigate the likelihood that artificial intelligence-based, non-invasive lie detection technologies are likely to experience a rapid advancement in the coming years, and examine the implications such an advance may bring.
