This paper proposes the point-wise matching method of online drawings. This medhod can be used as the pre-processing in on-line signature verification using only the positional information. After this pre-processing, various dynamical or local features of the signature can be used in verification. The test signature and the model one are to be matched point-wise by applying time-variant linear transformation. Fixed-interval smoother is used for estimating the time-variant transformation parameters.
