An Ügyfélkapu, a government authentication-based electronic signature service will be detailed in our paper. This service was designed to accomplish the rules of semantic Web and component-based design. The important milestones of the birth process of e-signature are described in our other paper, Electronic signature. The services of Electra Signature are described in this study. Thanks to the semantic Web infrastructures Electra can cooperate with other semantic Web-based applications, for example, FOAF using as a digital business card.
