Novel Impostors Detection in Keystroke Dynamics by Support Vector Machine
To detect the novel impostors whose data patterns have never been learned previously in keystroke dynamics, two solutions are proposed in this paper. The first solution employs two-class SVM and provides the training data with an overall coverage on the possible impostors. The second one uses oneclass SVM to capture the domain of the normal data patterns where probability lives. Test results ha...
متن کاملRetraining a Novelty Detector with Impostor Patterns for Keystroke Dynamics-Based Authentication
In keystroke dynamics-based authentication, novelty detection methods have been used since only the valid user’s patterns are available when a classifier is built. After a while, however, impostors’ keystroke patterns become also available from failed login attempts. We propose to retrain the novelty detector with the impostor patterns to enhance the performance. In this paper the support vecto...
متن کاملOutlier Detection for Support Vector Machine using Minimum Covariance Determinant Estimator
The purpose of this paper is to identify the effective points on the performance of one of the important algorithm of data mining namely support vector machine. The final classification decision has been made based on the small portion of data called support vectors. So, existence of the atypical observations in the aforementioned points, will result in deviation from the correct decision. Thus...
