Abstract: A control method is provided. The method includes, before the individual or group of individuals presents at the control point, initializing a control protocol of each individual, including retrieving freshly acquired biometric datum from each individual; extracting metadata associated with each datum; verifying the coherence of the extracted metadata; and comparing each freshly acquired biometric datum retrieved with a set of biometric reference data stored in a control server, so as to ascertain whether a controlled individual belongs to a list of individuals of interest; and when the individual or group of individuals presents at the control point: finalizing the control protocol of each individual and if either authentication and/or verification fails, subjecting the individual or the group of individuals to more intense scrutiny, and if both authentication and verification pass, authorizing the individual or the group of individuals to cross the control point.

Abstract: Detection and transmission modules respectively fitted on several wheels of the vehicle are set up to transmit a detection signal incorporating an indication of a state of the wheel. The sensed signal is compared with several waveforms, respectively stored in relation to wheel positions, in order to select a wheel position for which the stored waveform matches the sensed signal. After pre-processing the sensed signal and identifying extrema of the pre-processed signal, the comparison between the sensed signal and a waveform comprises applying a time transform to the pre-processed signal to align first and second extrema of the pre-processed signal with first and second extrema of said waveform and computing a distance between the transformed signal and said waveform. The wheel position selected is the one for which the computed distance is minimum.
