Paper Abstract
Three main topics of recent research on multimodal biometric systems are addressed in this article: The lack of
sufficiently large multimodal test data sets, the influence of cultural aspects and data protection issues of multimodal
biometric data. In this contribution, different possibilities are presented to extend multimodal databases by generating
so-called virtual users, which are created by combining single biometric modality data of different users. Comparative
tests on databases containing real and virtual users based on a multimodal system using handwriting and speech are
presented, to study to which degree the use of virtual multimodal databases allows conclusions with respect to
recognition accuracy in comparison to real multimodal data. All tests have been carried out on databases created from
donations from three different nationality groups. This allows to review the experimental results both in general and in
context of cultural origin. The results show that in most cases the usage of virtual persons leads to lower accuracy than
the usage of real users in terms of the measurement applied: the Equal Error Rate. Finally, this article will address the
general question how the concept of virtual users may influence the data protection requirements for multimodal
evaluation databases in the future.
