1. A computer-implemented method for autocorrelation based security monitoring and detection, comprising:
determining that input signal data transmitted to a white noise generator for generating white noise autocorrelates with itself at one or more time lags; and
responsive to determining that the input signal data transmitted to the white noise generator for generating white noise autocorrelates with itself at one or more time lags:
determining whether an autocorrelation in the input signal data transmitted to the white noise generator for generating white noise matches one or more predetermined input signal data patterns associated with a known event or individual.
