X Preface
Section 3 groups three biometric encryption applications. Chapter 8 proposes a user-
specific biometric key with multimodal biometric for encryption. In Chapter 9, the
authors apply a cryptography scheme known as the “Co-Z approach” to biometric
systems. Chapter 10 presents a novel remote authentication scheme based on the
secret-splitting concept for cloud computing applications.
Finally, Section 4 groups a number of novel biometric applications. Chapter 11
provides a comprehensive review of existing research work that exploits
electrocardiograms (ECGs) for human identification as well as addresses several
important technical challenges arise from this application. Chapter 12 investigates new
magnetic sensing technologies for use in biometrics. In Chapter 13, the authors study
run-time reconfigurable hardware platforms and hardware-software co-design
techniques for biometric systems. Embedded systems based on programmable logic
devices such as field programmable gate arrays (FPGA) are presented as case studies.
Chapter 14 proposes a contactless biometric system based on the combination of hand
geometry and palmprint using only low cost devices for medium security
environments. The device uses infrared illumination and infrared camera in order to
handle changing lighting conditions as well as complex background that contains
surfaces and objects with skin-like colors. In Chapter 15 the biometric concept is
applied to the fuel cells, microbial fuel cells and micromixer. The findings suggest that
a novel flow slab design would be useful to improve Proton Exchange Membrane Fuel
Cells (PEMFC) and can even be expanded to other types of cell, and the prototype will
be useful in the design of a optimal biophysical passive micromixer and even show the
feasibility and potential of biometric concept widely applied in biochemical, biological,
chemical analysis, fuel cell and bioenergy.
