Abstract
A REE can approve or deny authentication based on a sensor output signal and a secure element (SE) operatively coupled to the REE can detect a replay attack. A feature extractor produces a feature vector from the sensor output signal. The feature vector can be used to authenticate a user. Detecting the replay attack can include storing previous feature vectors, sending a security breached signal to the REE in response to determining that the feature vector equals one of the previous feature vectors, and storing the feature vector as one of the previous feature vectors. The REE can deny authentication in response to receiving the security breached signal.
