Preface
Throughout history, humankind has been progressing steadily in the generation
of knowledge and applications using such findings. In this context, different
revolutions have emerged across the years, such as in agriculture, industry,
technology, science, and, most recently, information. Information technologies
refer to the analysis, structuring and interpretation of vast amounts of data and
information available as an endless resource for research, and development
in different fields. Healthcare represents one among many other fields with
increasing applications of information technologies.
Biometric systems are some of the most notorious representatives of this
type of technology. These systems obtain relevant information regarding our
bodies and behaviors. Many innovative solutions under this scheme generate
biosensors, the development of personalized healthcare services, intelligent
fitness applications, wearable devices, and algorithms for predicting pathologies
and health risks based on readings and analyses of physiological features,
among other data. Thus, biometric systems provide the means to identify,
authenticate, and model individuals in a reliable way through unique
physiological and behavioral features. Ultimately, such systems generate
information and knowledge about the health and behavior of humans.
Biometrics has been an essential component in security, military, and
criminology, and new types of biometric systems are emerging as essential
platforms in healthcare, smart cities, and industrial business. Former and
seminal applications in health, ergonomics, transportation, industry, education,
neuromarketing, and arts could lead these efforts to develop biometric systems
to become an everyday asset. Such systems will strongly support the health,
wellness, and performance of humans. These are current opportunities as the
reliability and wearability of these technologies dare and inspire our researchers
to look for innovative solutions for humanity.
This book presents a compilation of biometric technologies studied and
developed in various research groups in Tecnologico de Monterrey, Mexico. A
summary of biometric systems as a whole provides a starting point for all readers.
It explains the principles behind physiological and behavioral biometrics. It
explores different types of commercial and experimental technology and current
and future applications in the fields of security, military, criminology, healthcare,
education, business, and marketing.
iv Biometry: Technology, Trends and Applications
The following chapters include more in-depth descriptions of research
methods and results from studies where biometric systems are the main
protagonists. Among the selected topics are
• The analysis of brain signals, or electroencephalography (EEG) in mobile
and home EEG in natural environments of children, as well as in the
monitoring of epileptic encephalopathies in children.
• The development of functional Human Machine Interfaces (HMI) and
Brain-Computer Interfaces (BCI).
• A description of the BCI framework and novel applications-oriented towards
rehabilitation, human performance, and treatment monitoring.
• Some t echniques as machine learning, deep learning, and artificial
intelligence aid in the diagnosis, seizure detection, and data-centered
medical decisions.
Finally, the authors highlight that this book is a compilation of biometric
systems, and many other exciting research proposals exist. Therefore, we hope
readers will become interested in such technology, and the invitation is open to
keep researching and innovating in this field.
