1. A method for applying a signature simplicity analysis for improving the accuracy of signature validation, comprising the steps of:

  • using a computer system to generate a plurality of synthetic fraudulent signatures for a person;

    encoding authentic signatures of the person using signature simplicity; and

    validating the signatures using signature simplicity;

    wherein the step of encoding authentic signatures using signature simplicity comprises the steps of;

    inputting a set of authentic signatures of the person;

    inputting a name of the person;

    creating an initial signature code for the person;

    validating the set of synthetic fraudulent signatures;

    using a set of simulation parameters as seeds to produce an updated set of synthetic fraudulent signatures;

    validating the updated set of synthetic fraudulent signatures against the initial signature code; and

    producing an adjusted signature code.
