In this paper the off-line type signature analysis have been considered. Signature image by means of three different approaches is analysed, what allows to define features (weights) of the signature. Different influences of such features were tested and stated. In this paper, personal signature is preprocessed and in the three stages signature is processed. In proposed approach the Hough transform is introduced, centre of signature gravity is determined, and the horizontal and vertical signature histograms are performed. Proposed approach gives good signature recognition level, hence described method can be used in many areas, for example in biometric authentication, as biometric computer protection or as method of the analysis of person's behaviour changes.
