Researcher in AI

Since our founding, IDEMIA has been on a mission to unlock the world and make it safer through our cutting-edge identity technologies. Our technology leadership makes us the partner of choice for hundreds of governments and thousands of enterprises in over 180 countries, including some of the biggest and most influential brands in the world. In applying our unique expertise in biometrics and cryptography, we enable our clients to unlock simpler and safer ways to pay, connect, access, identify, travel and protect public places – at scale and in total security.

Our teams work from 5 continents and speak 100+ different languages. We strongly believe that our diversity is a key driver of innovation and performance.

Deepfakes pose a significant threat to the reliability of information and the security of biometric systems. The candidate will be tasked with developing automatic deepfake detection algorithms to enhance the security of our biometric solutions.

IDEMIA is recruiting researchers to enrich and strengthen its teams. The goal is to cover all aspects of scientific research from data collection to modeling, implementation, and ultimately the publication of articles or patents. The methodologies employed include Bayesian approaches, machine learning, deep learning (CNN, Transformer, GAN, Diffusion, and VLM), as well as computer vision techniques for optimized analysis of still images and automated video processing.

Technological Environment :

• Rapid progress is currently being made in the field of Generative AI and deepfake technology [1, 2]
• Although deepfake videos are not yet perfect, they have already caused significant harm to many individuals [3], and it is widely acknowledged that they represent a serious threat to society
• For example, deepfakes have recently been used to attempt to misinform the Ukrainian armed forces [4]
• It is therefore of utmost importance that defenses against this threatening technology remain robust and up to date
• Public information campaigns and word-of-mouth have already made the general public more skeptical about videos coming from untrusted sources
• However, more systematic and reliable defense mechanisms are required
• In the absence of strict governance regarding media provenance and distribution, deepfake detection remains the only realistic option
• Automatic deepfake detection relies on deep learning–based classification methods, whose performance largely depends on the quality and quantity of data available for neural network training
