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 using a computer system to generate a plurality of synthetic fraudulent signatures for a person comprises the steps of;
inputting a name of the person;
inputting a set of simulation parameters;
performing a name mangling process to generate a set of various name versions based on the simulation parameter;
selecting a set of available fonts based on the simulation parameters;
selecting a set of available font characteristics based on the simulation parameters;
generating a set of initial signature images;
performing a name mangling process on all the initial signature images to create a plurality of intermediate signature images;
removing any image duplicates; and
outputting a set of unique synthetic signatures representing the person'"'"'s name.
