How I built the world’s most efficient deepfake detector with $100

At a time when disinformation and manipulation of opinion spread through social networks, it is necessary to be equipped to spot fake identities, especially via their profile pictures which are the hardest elements to fake. During this talk, you will discover a method to detect images generated via ultra-realistic deepfake generator ThisPersonDoesNotExist.com, with 100% reliability and even a way to know the exact time the photo was produced.

The talk will focus on a technical challenge faced during the implementation of one of the attacks, which involves TensorFlow models leveraging features of a customized ElasticSearch instance, on very limited hardware.
