Semantic biometrics
Gait and face biometrics have a unique advantage in that they can be used when images are acquired at a distance and signals are at too low a resolution to be perceived by other biometrics. Given such situations, some traits can be difficult to extract automatically but can still be perceived …

Fair electronic exchange using biometrics
Fair exchange between two parties can be defined as an instance of exchange such that either both parties obtain what they expected or neither one does. Protocols that facilitate such transactions are known as “fair exchange protocols”. We analyze one such protocol by Micali that demonstrates fair …

Feature-level fusion in multimodal biometrics
Multimodal biometric systems utilize the evidence presented by multiple biometric modalities (e.g., face and fingerprint, multiple fingers of a user, multiple impressions of a single finger, etc.) in order to determine or verify the identity of an individual. Information from multiple sources can …

Continuous user authentication featuring behavioural biometrics
… is pro- posed and implemented using behavioural biometrics i.e., keystroke and mouse dynamics which tends to authenticate the user on each sin- gle action. Behavioural biometrics are used since these can passively provide the perpetual information about the user’s behaviour when interacting with …

Identification and Security Implications of Biometrics
<p>The usage of biometrics has become more frequent over the past couple of decades, notably due to technological advancements. Evolving technology in the field of biometrics has also led to increased accuracy of associated software, which have provided the opportunity to use a multitude of …

Ocular Biometrics: Human Recognition in Challenging Conditions
The iris is the most reliable human biometric known to date. The iris texture has been shown to be effectively unique under ideal imaging conditions. However, as imaging constraints are relaxed, the iris becomes increasingly difficult to image, dra- matically decreasing its usability as an accurate …

Information Theoretic Methods For Biometrics, Clustering, And Stemmatology
… including biometric cryptosystems, cancelable biometrics, secret binding and secret generating systems, and salt biometric systems. In addition to attacks at the database, information leakage from communication links between sensor modules and databases is considered. A general information …

Three Factor Authentication Using Java Ring and Biometrics
… physical tokens, (something you possess) and biometrics, (something you are). Using any one of these techniques to secure a system always has its own set of threats. One way to make sure a system is secure is to use multiple factors to authenticate. One of the ways to use multiple factors is …

Adversarial Activity Detection and Prediction Using Behavioral Biometrics
<p>Behavioral biometrics can be used in different security applications like authentication, identification, etc. One of the trending applications is predicting future activities of people and guessing whether they will engage in malicious activities in the future. In this research, we study the …

On guided model-based analysis for ear biometrics
… we propose a new model-based approach to ear biometrics. Our model is a part-wise description of the ear structure. By embryological evidence of ear development, we shall show that the ear is indeed a composite structure of individual components. Our model parts are derived by a stochastic …

Development, Evaluation, and Analysis of Complex Eye Movement Biometrics
… solution to the challenges faced by modern biometrics. Consisting of both physical and neurological components, and due to the minute scale, the accurate replication of eye movements outside of a living subject is practically infeasible (if not impossible), providing an inherent level of …

Multimodal biometrics score level fusion using non-confidence information
Multimodal biometrics refers to automatic authentication methods that depend on multiple modalities of measurable physical characteristics. It alleviates most of the restrictions of single biometrics. To combine the multimodal biometrics scores, three different categories of fusion approaches …

Gestalt Biometrics and their Applications; Instrumentation, objectivity and poetics
This thesis is about the relationship between human bodies and instrumental technologies that can be use to measure them. It adopts the position that instruments are technological structures that evoke and manifest particular phenomena of embodied life. However, through their history of association …
