System for automatically maintaining reference signatures
First Claim
1. A method for maintaining a set of reference signatures for use in a signature verification system comprising:
- establishing reference signature data containing information corresponding to one or more reference signatures, capturing a first new set of signature information, associating that new set of signature information with an account, evaluating the first new set of signature information to determine whether it is suitable for comparison to the reference signature data, and if the new set of signature information is suitable for comparison to the reference signature data, determining whether the new set of signature information constitutes a match with one or more signatures included within the reference signature data, and if the new signature information does not constitute a match with signatures in the reference signature data, adding the new set of signature information to the reference signature data, and if necessary, replacing information corresponding to one or more reference signatures that matched with the new set of signature information.

Abstract
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.

19. A method for maintaining a set of reference signatures for use in a signature verification system comprising:
-
establishing reference signature data containing information corresponding to one or more reference signatures, capturing a first new set of signature information, associating that new set of signature information with an account, determining whether the new set of signature information constitutes a match with one or more signatures included within the reference signature data, and if the new signature information does not constitute a match with signatures in the reference signature data, adding the new set of signature information to the reference signature data, and if necessary, replacing information corresponding to one or more reference signatures that matched with the new set of signature information, wherein replacing information corresponding to one or more reference signatures that matched with the new set of signature information is done with a step selected from the group consisting of;
a) replacing the data corresponding to the oldest variant within the reference signature data, b) replacing the data corresponding to the oldest variant within the reference signature data whose hit rate is lowest, and c) replacing the data corresponding to the oldest variant within the reference signature data having the highest number of compares and the lowest number of hits.
