Literature Review Title: A Survey of Keystroke Dynamics Biometrics 
Chapter Title:  Keystroke Dynamics Quality Measure and Control. 
1. Abstract of Cited Paper (BIB001):  Keystroke dynamics-based authentication (KDA) is to verify a user's identity using not only the password but also keystroke dynamics. With a small number of patterns available, data quality is of great importance in KDA applications. Recently, the authors have proposed to employ artificial rhythms and tempo cues to improve data quality: consistency and uniqueness of typing patterns. This paper examines whether improvement in uniqueness and consistency translates into improvement in authentication performance in real-world applications. In particular, we build various novelty detectors using typing patterns based on various strategies in which artificial rhythms and/or tempo cues are implemented. We show that artificial rhythms and tempo cues improve authentication accuracies and that they can be applicable in practical authentication systems.

Literature Review:
When it comes to performance enhancement strategy, a lot of research works have been focusing on improving classification algorithms. However, BIB002 suggested that quality measure of keystroke patterns is a much more determinant criteria than classifier employed. Quality of user template has a direct impact on the performance of an authentication system BIB001 ; hence, designing a good and discriminative keystroke feature profile is a crucial process that should not be undermined.
