  • the device 100 may be provided with a program and one or more processors to complete the calculations.
  • Calculating a user profile based on the measured one or more behavioural biometrics of the user may comprise extracting one or more specific features from each respective behavioural biometric and then aggregating the one or more specific features from each respective behavioural biometric.

  • Feature extraction is a way to reduce the large amount of measurement data to a much smaller set, while still maintaining the user characteristics contained within the data. This significantly reduces the amount of data needed to be stored as user identification data. It is advantageous to use statistical features, as these are easy to compute, reducing the processing requirements. For example, from a specific measurement data set usable statistical features could include, mean, standard deviation, kurtosis and skewness for each of the data streams.
  • usable statistical features could include, mean, standard deviation, kurtosis and skewness for each of the data streams.
  • the data features are stored in a NxM feature matrix, where N is the number of features extracted from the data, and M is the number of data streams received from the measurement. In general, the more features are extracted, the higher the achieved accuracy is. In practice, a maximum of 4 features proves to be enough.
  • behavioural biometric measurements that do not generate a continuous data stream, such as button presses (on/off)

  • the data aggregation can for example be carried out by a matrix multiplication of the feature matrices derived from a first behavioural biometric and a second behavioural biometric. Other methods of data aggregation are also possible.
  • the procedure can also be carried out with a single behavioural biometric, however this will not have the advantage of the increased accuracy of the multimode calibration.

  • the calibration result is not stored and the calibration is ended without determining a user profile. This prevents the user from storing an inadequate and not repeatable movement, thus resulting in high risk of being unable to unlock or having inadequate protection (for example calibration without movement (stationary device 100); this would result in an easily hacked behaviour).
