This paper proposes an approach to verify signature using autonomous self-organized Neural Network Model, fused with fuzzy membership equation of fuzzy c-means algorithm, based on the features of the signature. To overcome limitations of the functional approach and parametric approach among the conventional on-line signature recognition approaches, this paper presents novel autonomous signature classification approach based on clustering features. Thirty-six global features and twelve local features were defined, so that a signature verifying system with FE-SONN that learns them was implemented. It was experimented for total 713 signatures that are composed of 155 original signatures and 180 forged signatures yet 378 original signatures written by oneself. The success rate of this test is more than 97.67%. But, a few forged signatures that could not be detected by human eyes could not be done by the system either.
