In order to permit verification of a signature at a point remote from initial registration of a standard signature and without reference to a central data bank, the process of generation of the standard signature at the point of registration is analysed and a transform of the standard signature derived therefrom. Both the signature and the transform are recorded on an item, for example a traveller's cheque or a credit card. When the traveller's cheque is presented for encashment, the signature of the person presenting it may be verified by deriving a transform of the signature as generated by the person and comparing the transforms. Whereas the signatures may appear visually identical, a fraudulent signature will not have been produced in the same manner as the original standard signature and the transforms will differ. |
