Abstract

The present invention relates in general to electronic commerce realized in communications networks and more specifically to a new type of method and a new type of system for verifying electronic signatures and to a new type of electronic signature device. The solution according to the present invention provides additional flexibility and is still providing a simple solution in which also unstructured data can be used and utilized.
