A system to capture and to automate the maintenance of reference signatures for automatic signature verification systems. Generally, signatures as well as the identity of a person are captured from customer opening forms or recorded when subscribing for a service, which requires automatic signature verification. The identity (example customer name) and acquired signatures are stored into a database for later signature verifications required by business transactions. Rather than storing the initial reference signatures into the database, which is a manual time consuming process, signatures are taken from valid transactions and automatically stored into the database as a kind of reference signature. In paper based transactions the signature area of the document's image is taken and stored into the database as a so called "variant" to the reference customer or service identity. In paperless transactions the signature is taken directly from the input device and stored as a variant. This leads to a significant reduction in initial manual and continuous maintenance work needed. As individuals show variations in signatures over the years or they sign in two or several different forms (example: first name and last name or only last name), the signature reference database keeps the most up-to-date signature references without manual intervention.
