Improving Single Modal and Multimodal Biometric Authentication Using F-ratio Client-Dependent Normalisation

This study investigates a new client-dependent normalisation to improve a single biometric authentication system, as well as its effects on fusion. There exists two families of client-dependent normalisation techniques, often applied to speaker authenticat ...

An Investigation of F-ratio Client-Dependent Normalisation on Biometric Authentication Tasks

Samy Bengio, Norman Hoon Thian Poh

This study investigates a new \emph{client-dependent normalisation} to improve biometric authentication systems. There exists many client-de-pendent score normalisation techniques applied to speaker authentication, such as Z-Norm, D-Norm and T-Norm. Such n ...

Advanced Peer-to-Peer Networking: The P-Grid System and its Applications

Karl Aberer, Manfred Hauswirth, Philippe Cudré-Mauroux, Anwitaman Datta, Roman Schmidt, Jie Wu, Zoran Despotovic

The limitations of client/server systems become evident in an Internet-scale distributed environment. Peer-topeer (P2P) systems offer an interesting alternative to traditional client/server systems: Every node acts both as a client and a server and “ ...

Generating Synchronization Contracts for Web Services

Alain Wegmann, Otto Preiss

Component composition and Web-service composition have in common that the usage pattern of a certain black-box component or Web-service needs to be described precisely. Because usually many interactions between the client and the service provider are requi ...

Joint Server Scheduling and Proxy Caching for Video Delivery

Pascal Frossard

We consider the delivery of video assets over a best-effort network, possibly through a caching proxy located close to the clients generating the requests. We are interested in the joint server scheduling and prefix/partial caching strategy that minimizes ...

Chasing the FLP Impossibility Result in a LAN or How Robust Can a Fault Tolerant Server Be?

André Schiper, Xavier Défago

Fault tolerance can be achieved in distributed systems by replication. However, Fischer, Lynch and Paterson have proven an impossibility result about consensus in the asynchronous system model. Similar impossibility results have been established for atomic ...
