• This paper discusses an on-line signature verification method based on angular direction of pen-point movement (ADPM). The locus of pen-point movement is approximated by N line segments with a constant length. In this case, it is assumed that the variation of the angular direction along the locus can be described as an autoregressive (AR) process by considering the variations of angular direction as time series. Under this assumption the feature of handwriting motion is extracted by taking the discrete cosine transform (DCT) on the logarithms of the power spectral density (PSD) of the AR process. Signature verification experiments on a data base of four hundred KANJI signatures from four individuals were attempted. Type I (false rejection) error rates were 15-25% while Type II (false acceptance) error rates were 20-30%.
