8. Opportunities for Research Authentication based solely on subject in question.  Separate sets of data holding only within and between class records for each subject,  Rather than comparing a community of subjects to a community of records.  Higher accuracies could be legitimately obtained in this manner.

9. Conclusion The study has furthered previous studies at Pace University through running experiments on Mouse Movement, Stylometry, and Keystroke Biometric data, new and previously obtained, using the data mining tool Weka. The data mining algorithms with which the experiments were conducted are widely used and provide an entry point for future researchers into the use of data mining with biometric data sets.
