Abstract:
A method for training a classifier for authenticating signatures hand-drawn on an electronic input element includes receiving a set of multiple signature properties of each of multiple signatures documented over a time range of a common user, each set of multiple signature properties is associated with a time period during which a respective signature was documented at the time range, wherein the plurality of signatures were hand-drawn and digitally recorded using an electronic input element; generating a signature authenticating classifier for authenticating additional signatures of the common user based on the set of multiple signature properties of each of the plurality of signatures, wherein a weight assigned to each the set of multiple signature properties or a portion thereof decreases overtime, the weight is used for the generation of the classifier; and providing the signature authenticating classifier for authenticating the additional signatures

Claim (Index 7):
A method for authenticating signatures hand-drawn and digitally recorded using an electronic input element, comprising:\n receiving a signature authentication classifier for authenticating signatures of a common user based on a set of a plurality of signature properties of each of a plurality of signatures of the common user documented over a time range, wherein a classifier weight assigned to at least a portion of the plurality of signature properties of each set of a plurality of signature properties decreases over time, and the classifier weight is used for the generation of the classifier; receiving, from the common user, a signature for authentication, the signature being hand-drawn and digitally recorded using an electronic input element; and authenticating the received signature by applying the classifier to the received signature, the authenticating comprises: authenticating the received signature of the common user by applying said signature authentication classifier generated based on a set of a plurality of signature properties of each of a plurality of signatures documented over a time range of the common user, wherein said classifier weight is calculated based on a combination of at least one of: (i) common user specific coefficients and multi-user coefficients; and (ii) static features and dynamic features, the features extracted from the set of plurality of signature properties of each of the plurality of signatures documented over the time range, (iii) the classifier weight is used for the generation of the classifier; and providing an authentication result.
