1. A method for verifying integrity of a computing process, comprising:

  • determining a trait associated with the computing process;

    determining a pattern statistic associated with the trait based in part on an execution of the computing process in a normal condition, wherein determining the pattern statistic further comprises;

    determining consecutive data associated with the trait;

    employing a graphical representation to convert the consecutive data to a radius-vector;

    if the radius-vector is mature, retaining an endpoint coordinate associated with the radius-vector;

    determining a frequency pattern associated with the trait; and

    employing the graphical representation in part to convert the frequency pattern to an average directional vector;

    determining a prototype statistic associated with the trait based in part on another execution of the computing process in another condition;

    comparing the pattern statistic to the prototype statistic; and

    if the comparison indicates abnormal behavior the computing process, performing a predetermined action.
