Presents a fractal transformation based technique for signature verification. In this method, the fractal code of the reference signature locus is applied to a test signature locus and a sequence of fractal decoded test loci is obtained. The successive distances between the decoded test loci transforming towards the fractal attractor are compared to those obtained from the genuine reference signatures. The verification decision is derived from the rate of change of these distances. The experiment shows that the current implementation of the fractal transformation based verification algorithm is effective for random forgery detection.
