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).
