Claim 6:
7. A method comprising:
determining whether a processing unit needs to enter a secure mode;
entering the processing unit into the secure mode;
changing an execution environment of the processing unit to the secure environment;
while in the secure environment, receiving digital sensor data from a motion sensor over a signal acquisition time;
deleting a beginning portion of the digital sensor data in the signal acquisition time;
suppressing signal components in the digital sensor data associated with voluntary movement of the user;
signal processing the suppressed digital sensor data to extract signal features representing neuro muscular tone of the user;
tabulating the extracted signal features over periods of time of the signal acquisition time into a feature vector table;
performing a training operation with the feature data to generate model parameters fora predictive model; and
storing the model parameters for inferential use with the predictive model to perform a user based application, wherein the user based application is one or more of authenticating a user, encrypting user data; granting user access to a secured area; logging into a user to a computer system; and logging into a software application.
