Abstract:

The ability to prevent unauthorized users from gaining access to classified or sensitive data is crucial to many organizations, especially the military. There has been significantly increased attention in recent years in biometrics technology in order to provide more secured access controls to information systems. Different technologies and various products have been developed to authenticate users at entrances. However, once a user has logged on to a system, there is currently no mechanism to monitor the users identity. It is important to ensure that the user, throughout the communication, is the authorized user for high-security applications. The objective of this project is to develop a demonstration system that will automatically log off a PC when the users face disappears for an adjustable time interval. In this report, a brief overview of face detection technologies is provided. The particular neural network-based face detection algorithm employed in the demo system is discussed in more detail. It is followed by the design of the demo system, and discussion of technical issues encountered during the development.
