DESCRIPTION OF ATVS-SG_NOTE
The SG-NOTE dynamic signature database was captured in two
different sessions with an average gap of 5 days between them. In
each session, signatures were acquired in two blocks of 5 samples,
with a short break between blocks. No skilled forgeries are
available in this database. Consequently, the database contains a
total amount of 500 signatures (2 sessions with 25 users and 10 signatures per session). See
Fig. 1 for an example signature acquisition in SG-NOTE.
