Novel approaches to biometric security with an emphasis on liveness and coercion detection

Student thesis: Doctoral Thesis


Chapter One contains the introduction, sets the context and aims of the research and highlights the original contribution to knowledge along with publications gained from this research. Chapter Two will cover the methodological choice, which is grounded theory, as well as highlighting other potential methodologies that while are viable have not been used. Chapter Three will identify the background to biometric security while identifying some of the key areas that are currently lacking such as an appropriate way of measuring liveness detection techniques as well as the entire coercion detection sub-discipline. Chapter Four discusses the development of a new taxonomy that will classify liveness detection while moving away from the current ordinal measurement system used within the research area. Analysis of these liveness classifiers will then follow leading into the adaptation of the taxonomy of coercion detection techniques. Further development of these new techniques will follow, identifying metrics for coercion detection and an analysis of the proposed classifiers. After the taxonomy development Chapter Five analyses coercion and liveness techniques by 1.6 Published Work 7 applying the taxonomy across a selection of liveness and coercion techniques. This will then be followed by the development of an algorithm to denote the level of security an individual technique has achieved. Explanation of the algorithm development, components and testing will then be included. Finally Chapter Six will contain the final concluding remarks and will cover some of the areas in the future that can be looked into, alongside some focuses for article and conference submission
