Multi-IVE: Privacy Enhancement of Multiple Soft-Biometrics in Face Embeddings
Sébastien Marcel, Hatef Otroshi Shahreza
This study focuses on the protection of soft-biometric attributes related to the demographic information of individuals that can be extracted from compact representations of face images, called embeddings. We consider a state-ofthe-art technology for soft- ...
IEEE COMPUTER SOC2023Indexing Protected Deep Face Templates by Frequent Binary Patterns
Sébastien Marcel, Hatef Otroshi Shahreza
In this work, we present a simple biometric indexing scheme which is binning and retrieving cancelable deep face templates based on frequent binary patterns. The simplicity of the proposed approach makes it applicable to unprotected as well as protected, i ...
IEEE2022Building a path towards responsible use of Biometrics
Like many other enterprises, humanitarian organizations are investing in their digital transformation. In this sector, an important effort is put into biometric solutions. The ICRC has been exploring new ways of how they could integrate biometrics into the ...
2021Generating Master Faces for Use in PerformingWolf Attacks on Face Recognition Systems
Due to its convenience, biometric authentication, especial face authentication, has become increasingly mainstream and thus is now a prime target for attackers. Presentation attacks and face morphing are typical types of attack. Previous research has shown ...
IEEE2020Vulnerability Analysis of Face Morphing Attacks from Landmarks and Generative Adversarial Networks
Sébastien Marcel, Eklavya Sarkar, Laurent Colbois
Morphing attacks is a threat to biometric systems where the biometric reference in an identity document can be altered. This form of attack presents an important issue in applications relying on identity documents such as border security or access control. ...
Idiap2020Smartphone Multi-modal Biometric Authentication: Database and Evaluation
Sébastien Marcel, Amir Mohammadi
Biometric-based verification is widely employed on the smartphones for various applications, including financial transactions. In this work, we present a new multimodal biometric dataset (face, voice, and periocular) acquired using a smartphone. The new da ...
Idiap2020DOMAIN ADAPTATION FOR GENERALIZATION OF FACE PRESENTATION ATTACK DETECTION IN MOBILE SETTINGS WITH MINIMAL INFORMATION
Sébastien Marcel, Amir Mohammadi
With face-recognition (FR) increasingly replacing fingerprint sensors for user-authentication on mobile devices, presentation attacks (PA) have emerged as the single most significant hurdle for manufacturers of FR systems. Current machine-learning based pr ...
IEEE2020Evaluation Methodologies for Biometric Presentation Attack Detection
Sébastien Marcel, André Anjos, Ivana Chingovska, Amir Mohammadi
Presentation attack detection (PAD, also known as anti-spoofing) systems, regardless of the technique, biometric mode or degree of independence of external equipment, are most commonly treated as binary classification systems. The two classes that they dif ...
Springer International Publishing2019Recent Advances in Face Presentation Attack Detection
Sébastien Marcel, André Anjos, Amir Mohammadi
The undeniable convenience of face-recognition (FR) based biometrics has made it an attractive tool for access control in various applications, from immigration-control to remote banking. Widespread adopti
on of face biometrics, however, depends on the how ...
Springer2019Learning How To Recognize Faces In Heterogeneous Environments
Face recognition is a mature field in biometrics in which several systems have been proposed over the last three decades.
Such systems are extremely reliable under controlled recording conditions and it has been deployed in the field in critical tasks, suc ...
