A set of sampled data points, associated with a different position along the signature are compared with a set of characterising nodes in a pre-stored user profile. If each identified characterising node lies within a predetermined threshold range of a corresponding predetermined characterising nodethen a positive verification is made. The data points may comprise a time component relating to the interval between a data point and an adjacently located sample data point, or a distance of separation between nodes, or a vector of both time and spatial components. Optimisation matching may be used, to select the highest correlation with stored signature profiles, and to authorize a financial transaction remotely. A hash may be taken to ensure that the new signature is unique. |
