Abstract
For user authentication, finger touch information from a user is accepted via a touch sensitive element, the finger touch information including at least a time series of finger touch samples that define a trace of the user's signature, and each of the finger touch samples including centroid coordinates and non-centroid information, the non-centroid information including at least one of (A) a shape of the finger touch sample, (B) a size of the finger touch sample, (C) an orientation of the finger touch sample, and (D) characteristics of a multi-touch finger touch sample. A similarity of such finger touch samples with previously entered and stored finger touch samples is determined and compared with a threshold for purposes of user authentication.
