| Abstract | ||
| Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be. As the dependence upon computers and computer networks grows, the need for user authentication has increased. User’s claimed identity can be verified by one of several methods. One of the most popular of these methods is represented by (something user know), such as password or Personal Identification Number (PIN). Biometrics is the science and technology of authentication by identifying the living individual’s physiological or behavioral attributes. Keystroke authentication is a new behavioral access control system to identify legitimate users via their typing behavior. The objective of this paper is to provide user authentication based on keystroke dynamic in order to avoid un authorized user access to the system. Naive Bayes Classifier (NBC) is applied for keystroke authentication using unigraph and diagraph keystroke features. The unigraph Dwell Time (DT), diagraph Down-Down Time (DDT) features, and combination of (DT and DDT) are used. The results show that the combination of features (DT and DDT) produces better results with low error rate as compared with using DT or DDT alone. | ||
