java code for user authentication using keystroke dynamics

Abstract

Keystroke dynamics, keystroke biometrics or typing dynamics, is the detailed timing information that describes exactly when each key was pressed and when it was released as a person is typing at a computer keyboard.In today’s scenario there is a major threat to misuse the personal as well as official data. Data which is easily accessible from the storage device by an unauthenticated user is a major concern and needs to be eradicated. Increase in number of software and devices for hacking and cracking causes gains in unauthorized access which results in exploitation of important data.
Methods like user ID and password which is mostly used as security is now not reliable and secure due to rapidly increase in hackers and crackers. Also this method no longer provides consistent safety measures because passwords are prone to shoulder surfing and passwords can also be hacked. To gain secure and efficient access either user must change his passwordfrequently or the user should use strong password (combination of alphabets, numeric and special symbols). Users do not respect these conditions as theyfeel them quite strict and difficult to be applied. The solution to above said problems is keystroke dynamics.Keystroke Dynamics is a behavioral biometric approach to enhance the computer access rights. It verifies the
individual by its keystroke typing pattern. Keystroke biometric is based on the assumption that the typing pattern of each user is unique. The objective of this review paper is to summarize the well-known approaches used in keystroke dynamics.
