TLDR
This paper uses two leading machine learning approaches: Support Vector Machine with Radial Basis Function (SVM-RBF) and Fuzzy-Rough Nearest Neighbour with Vaguely Quantified Rough Set (FRNN-VQRS) on multiple publicly available authentic and recognized keystroke dynamics datasets to demonstrate the impact of soft biometric traits.Abstract:
Identifying soft biometric traits such as gender, age group, handedness, hand(s) used, typing skill and emotional states from typing pattern and the inclusion of these traits as additional features in user recognitionis a recent research area in order to improve the performance of keystroke dynamics technique. Knowledge-based user authentication with the combination of keystroke dynamics as biometric characteristics relates the issues to user authentication/identification in cloud computing based applications. Our approach is the one way, where the performance of the keystroke dynamics biometricin user recognition can be improved by using soft biometric traits that provides some additional information about the user which can be extracted from the typing pattern on a computer keyboard or touch screen phone. These soft biometric traits have low discriminating power but can be used to enhance the performance of user recognition in accuracy and time efficiency. In this paper, we are interested in using this technique in thestatic keystroke dynamics user authentication system. It has been observed that the age group (18−30/30+or < 18/18+), gender (male/female), handedness (left-handed/right-handed), hand(s) used (one hand/both hands), typing skill (touch/others) and emotional states (Anger/Excitation) can be extracted from the way of typing on a computer keyboard for single predefined text. This soft biometric information from typing pattern as extra features decreases the Equal Error Rate (EER). We have used two leading machine learning approaches: Support Vector Machine with Radial Basis Function (SVM-RBF) and Fuzzy-Rough Nearest Neighbour with Vaguely Quantified Rough Set (FRNN-VQRS) on multiple publicly available authentic and recognized keystroke dynamics datasets. Our approach on CMU keystroke dynamics datasetsindicates the impact of soft biometric traits.read more

TL;DR: In this paper, soft biometric is used as secondary information to improve the recognition accuracy for primary keystroke biometric system and can be further improved using SVM as machine learning under the score level fusion in the combination approach.

Fuzzy-rough nearest neighbour classification and prediction
Richard Jensen,Chris Cornelis +1 more
TL;DR: This paper proposes an NN algorithm that uses the lower and upper approximations from fuzzy-rough set theory in order to classify test objects, or predict their decision value, and shows that it outperforms other NN approaches and is competitive with leading classification and prediction methods.

Fuzzy-rough nearest neighbor algorithms in classification
TL;DR: It is shown that the proposed classifier generalizes the conventional and fuzzy KNN algorithms and can distinguish between equal evidence and ignorance, and thus the semantics of the class confidence values becomes richer.
