The legislation (and especially European Directive 1999/93/EC of 13 December 1999) defines the electronic signature as data in electronic form which are attached to or logically associated with other electronic data and which serve as a method of authentication.
Today any written electronic document is accepted as evidence on the same account as a written document on paper, provided that the person it comes from can be duly identified and that this electronic document is established and kept in appropriate conditions so as to guarantee its integrity. The Universign electronic signature has been developed to be in perfect compliance with this legal frame.
