Forskning

SALT (2022 - 2026) funded by Norwegian Research Council

SALT, (Secure privacy preserving Authentication using faciaL biometrics to proTect your identity) project will develop new algorithms for privacy preserving, presentation/Morphing attack detection techniques on face biometrics.

“OffPAD” - Optimizing balance between high security and usability (2022-2025)

“OffPAD” project will develop cryptographic tools and presentation attack detection techniques for fingerprint biometrics.

Secure Access Control over Wide Area Network (SWAN) (2015-2020)

The SWAN-project will develop innovative technologies and countermeasures to mitigate presentation attacks (also coined as spoofing attacks), which lead to a usable, economic, and privacy-preserving access control platform based on biometrics.
