The mGov4EU project started with a comprehensive analysis of the state-of-the-art. This covered areas as diverse as mobile identity, mobile government and cross-border data exchange, all relevant to the project’s objectives. In gaining in-depth knowledge of the state of play, a reference architecture has been established which defines the core components on electronic identity, electronic signature, single digital gateway elements and a digital identity wallet. This reference architecture has been further refined and modularised to building blocks that shall support the implementation of cross-border use cases. mGov4EU itself aimed at demonstrating such use cases through pilots spanning areas as broad as i-voting, smart mobility, or electronic signatures. The project has, thus, derived comprehensive and concrete requirements stemming from the pilot domain and these requirements have been mapped to the building blocks. This resulted in the implementation of four software building blocks; eIDAS-based cross-border authentication, SDGR-based cross-border data retrieval, cross-border e-signature solutions, and identity wallet. These building blocks have been tested in three concrete pilots, i-voting, smart mobility, and electronic signatures. Pilots and buildings blocks got iteratively improved following the learnings from the evaluation activities.
As a horizontal activity, the evaluation framework and privacy and ethical aspects have been developed. This comprised work on the pilot evaluation that developed trans-disciplinary indicators and security evaluation where potential candidate methodologies have been screened. In order to address ethics, gender, and legal aspects, an ethics and gender management framework has been established. Further horizontal aspects were communication and dissemination, where electronic channels like the Web and social media have mainly been targeted and several scientific publications have been made. The project results have been presented in a symposium as a final event, as well have been published in a book.
