The ALIZE Project

ALIZE Project - Open source platform (LGPL) for biometrics authentification

The main objective of this project is to facilitate access to biometric technologies for academic's (centre for research and education) and industrial's. To achieve this objective, ALIZE project provide an efficient, modular, and easy to master platform, capable of managing differents biometrics tasks, in different environments. One of the expected impact of the project is to animate a strong community of users of the ALIZE platform , composed of academic and industrial players. Major originality of ALIZE, is proposal of a single recognition engine for multiple modalities: primarily voice and face. ALIZE is also available on different operating systems(Linux / Windows / Mac OSX). For users of ALIZE, adoption of a unique and free recognition engine, allows to focus on research and development efforts on specific aspects of the modality studied, rather than on the development and monitoring of complex low level softwares engines.

With ALIZE, it's becomes easier to integrate new methods based on the know-how acquired over those already studied. Furthermore this approach simplifies the integration of biometrics in demonstrators or products, and fusion of different modalities. This is essential because multimodality should play a significant role in next generation of biometric systems. ALIZE is the continuation of previous biometrics projects TECHNOLANGUE AGILE/ALIZE completed in January 2005 and Mistral project (founded by French National Research Agency) completed in 2009.

Biometrics library ALIZE is today widely used by an international community of academic's and industrial's users. Those users are very active and prolific (as shown on the "project pages of ALIZE Website), and demonstrate that free software, when published trough a scientific collaboration, with respect to the rules of software engineering (UML standards), have great potential. ALIZE has obtained very good results in major international evaluation campaigns - NIST SRE, RT - and French - ESTER. The performance of ALIZE will also be tested by modality modality, through regular participation in various international campaigns.
