Handwritten signature attributes for its verification

Handwritten signature verification is a biometric technology that uses the signature for identification purposes with the aim of establishing the authority for making automated transactions, obtaining access to computer terminals or physical access to the controlled area. The effectiveness of biometric verification is determined mainly by difference of attributes used for authentication. The paper examines authentication systems based on handwritten signature and the main informative parameters of signature such as size, shape, velocity, pressure, etc. We analyzed their statistical characteristics and considered methods to extract them using Wavelet transform, discrete Radon and Fourier transforms. Handwritten signature data acquisition methods were investigated in order to design an effective verification algorithm.
