  • Anti-spoofing for contactless fingerprint readers
    Patent number: 11514708
    Abstract: Contactless fingerprint reader. The contactless fingerprint reader has one or more light sources adapted to emit light under different lighting conditions, a first camera adapted to successively capture first images of a subject captured with and without flash light, at least one second camera adapted to capture second images from different angles, one or more sensors adapted to generate one or more spatial-temporal signals representing a change of a distance between said subject and one or more locations of the contactless fingerprint reader, and communication module for sending the first images, said second images, and the one or more spatial-temporal signals to an anti-spoofing device.

  • Biometric sensor and processor pairing
    Patent number: 11210414
    Abstract: The present invention relates to a biometric system (FBS) comprising a sensor (FS) and a secure execution environment (SEE) as separate physical components, said biometric system being intended to be used in cooperation with a biometric application (BA), wherein said secure execution environment (SEE) comprises a data processing component (DP) and a secure memory (SEM) storing data enabling to access calibration data as determined at the time of the physical pairing of the sensor (FS) and the secure execution environment (SEE), said data processing component (DP) using the calibration data as retrieved when raw biometric data are received from the sensor (FS) to produce biometric sample to be used in the biometric application (BA).
