To Uncover a Deepfake Video Call, Ask the Caller to Turn Sideways - Metaphysic.ai

There is an interesting vulnerability in video deepfakes that, to date, has been generally overlooked by the security research community, perhaps because'live', real-time deepfakes in video calls have not been a major cause for concern until very recently. For a number of reasons, which we'll examine in this article, deepfakes are not usually very good at recreating profile views: The above examples are taken* from a session with tech exponent and commenter Bob Doyle, who agreed to run some tests with us, using DeepFaceLive to change his appearance to that of a series of popular celebrities. DeepFaceLive is a live-streaming version of the popular DeepFaceLab software, and is capable of creating alternate video identities in real-time. For these tests, Bob used a mix of models downloaded from deepfake communities, as well as some community-trained models that come bundled with the DeepFaceLive application. From more or less face-on viewpoints, most of the celebrity recreations are quite effective, and some are very convincing even at fairly acute angles – until the facial angle hits a full 90 .
