Keystroke authentication systems available in the market are mostly software-based.This is due to the ease of use as well as the low cost of the mechanism.Any new keystroke www.intechopen.comDesign and Evaluation of a Pressure Based Typing Biometric Authentication System 237 authentication system has to consider these factors in the design.Likewise, the system designed for PBAS uses simplified hardware which minimizes the cost of production.The system is designed to be compatible with any type of PC.Moreover, it does not require any external power supply.In general, the system components are low cost and commonly available in the market. System hardware componentsThe hardware layout of the system is unique.It consists of a desktop computer equipped with a data acquisition card, and a specially designed alphanumeric keyboard embedded with pressure sensors (Eltahir et al., 2003).As illustrated in Figure 3, the main hardware components of PBAS are as follows: 1. Alphanumeric keyboard (biokeyboard) embedded with force sensors to measure the keystroke pressure while typing.2. Data Acquisition System consisting of the following components: a. Analogue Interface Box (filtering and amplification of signal).b.DAQ PCI card fitted onto the PC. 3. PC/central processing unit (CPU) for running the PBAS program using Windows XP operating system.
