Abstract

The authors propose a statistical model for signature verification by computer. The model recognizes that repeated signatures by the owner are similar but not identical. The model consists of a template signature for each individual, and several factors which allow for variations in each rendition of this template. These variations include the speed of writing, as well as slowly varying affine transformations size as size, rotation and shear. The estimated template represents the mean of a sample of signatures from an individual, and the variations in the factors can be used to establish several measures of variance. These quantitative measures are essential for reliable signature verification
