Claim One:
1. A method of handwritten signature verification comprising: at a first location obtaining reference signature data in the form of time series data relating to a plurality of attributes of at least one reference signature; dynamically capturing time series data as a signature to be verified is made at a second location, the dynamically captured time series data relating to a plurality of attributes of the signature to be verified, the time series data of the signature to be verified being obtained without tracing, at least one of said at least one reference signature and said signature to be verified being obtained with a signature capture device coupled to a processor; comparing attribute data of the reference signature to attribute data related to the dynamically captured time series data of the signature to be verified using time series analysis, wherein a processor is programmed to perform time series analysis; comparing attribute data of the reference signature to attribute data related to the dynamically captured time series data of the signature to be verified using spectral analysis, wherein the processor is programmed to perform spectral analysis, the comparison being based upon at least two sets of attribute data from each of the at least one reference signature and at least two sets of attribute data from the signature to be verified; and determining if the signature to be verified matches the reference signature based on the comparisons.
