Query: On-line signature verification system with failure to enroll managing   In this paper we simulate a real biometric verification system based on
on-line signatures. For this purpose we have split the MCYT signature database
in three subsets: one for classifier training, another for system adjustment
and a third one for system testing simulating enrollment and verification. This
context corresponds to a real operation, where a new user tries to enroll an
existing system and must be automatically guided by the system in order to
detect the failure to enroll situations. The main contribution of this work is
the management of failure to enroll situations by means of a new proposal,
called intelligent enrollment, which consists of consistency checking in order
to automatically reject low quality samples. This strategy lets to enhance the
verification errors up to 22% when leaving out 8% of the users. In this
situation 8% of the people cannot be enrolled in the system and must be
verified by other biometrics or by human abilities. These people are identified
with intelligent enrollment and the situation can be thus managed. In addition
we also propose a DCT-based feature extractor with threshold coding and
discriminability criteria.
