Abstract: Identifying a user based on the analysis of his/her typing pattern is termed as keystroke dynamics. There are four processes involved in keystroke dynamics. They include feature extraction, feature selection and classification. Initially the statistical measures of feature characteristics such as latency, duration and digraph are computed. Artificial bee colony algorithm is implemented for feature selection. The selected features are classified using a hybrid distance measure. A moderate efficiency was achieved with the obtained results.

Keywords: keystroke dynamics; feature extraction; feature selection; artificial bee colony; ABC algorithm; classification; receiver operating characteristic; ROC curve; distance measures; typing patterns.
