    The hardware design of a pressure based typing biometrics authentication system (BAS) is discussed in this paper. The dynamic keystroke is represented by its time duration (t) and force (F) applied to constitute a waveform, which when concatenated compose a complete pattern for the entered password. Hardware design is the first part in designing the complete pressure-based typing (BAS) in order to ensure that the best data to represent the keystroke pattern of the user is captured. The system has been designed using LabVIEW software. Several data preprocessing techniques have been used to improve the acquired waveforms. An experiment was conducted to show the validity of the design in representing keystroke dynamics and preliminary results have shown that the designed system can successfully capture password patterns.
