Definition

A large scale biometric system is a system involving the authentication of a huge number of users via the biometric features. A Large Scale Biometric Database is generally designed for civilian applications and is not merely the increased size of database compared to the personal use system. In the case of a large scale system, there is greater emphasis on the issues of system reliability and flexibility. To meet the requirements of public use, the system must have a high enrollment rate and adapt to environmental variations. Security is another issue in designing such a system due to the large number of users enrolled. A one-to-many matching may sometimes lead to system breakdown, thus other authentication policies may be applied to complement the one-to-many matching to enhance system reliability, such as cross validation of multiple biometric features.
