Can multibiometrics improve performance 论文

摘要

While it is widely acknowledged that the perfor-mance improvement in current biometrics-based per-sonal authentication systems is necessary, it is not clear what mechanisms could be used to improve the performance. In this paper, we formulate the prob-lem of multiple biometrics integration and examine whether the improvement in performance could be achieved from integrating multiple biometrics. For two practical and commonly used situations of multibio-metric integration, we analyze the performance gains. We also demonstrate empirically that integration of multiple biometrics does indeed result in a consistent and signicant performance improvement. 1
