Design and Performance of Biometric System [PDF ebook] 

The use of biometrics to confirm personal identity has become a key component to our nation’s security. And, as such, there is an escalating need to design and develop biometric systems which accurately and effectively identify individuals. To date, biometric technologies are the most definitive, real-time identity management tools currently available, yet many shortcomings of these tools have yet to be addressed. This book works to introduce designers to the concept of usability and showcase the ways in which a properly implemented user-centered design process can improve a system’s effectiveness, and efficiency, and user satisfaction.
