Interoperability of Biometric Systems: Analysis of Geometric Characteristics of Handwritten Signatures
Handwritten signatures are considered one of the most useful biometric traits for personal verification. In the networked society, in which a multitude of different devices can be used for signature acquisition, specific research is still needed to determine the extent to which features of an input signature depend on the characteristics of the signature apposition process.
In this paper an experimental investigation was carried out on constrained signatures, which were acquired using writing boxes having different area and shape, and the different behaviour of geometric features with respect to the writing boxes is discussed.
