Face recognition systems are used for user authentication in everyday applications such as logging into a laptop or smartphone without need to memorize a password. However, they are still vulnerable to spoofing attacks, as for example when an imposte... Read More about Designing a facial spoofing database for processed image attacks.

Resilience of Luminance based Liveness Tests under Attacks with Processed Imposter Images (2016)
Presentation / Conference Contribution
Omar, L., & Ivrissimtzis, I. (2023, May). Resilience of Luminance based Liveness Tests under Attacks with Processed Imposter Images. Presented at 24th International Conference in Central Europe on Computer Graphics, Visualization and Computer Vision 2016 (WSCG 2016)., Plzen, Czech Republic

Liveness tests are techniques employed by face recognition authentication systems, aiming at verifying that a live face rather than a photo is standing in front of the system camera. In this paper, we study the resilience of a standard liveness test... Read More about Resilience of Luminance based Liveness Tests under Attacks with Processed Imposter Images.
