Design and Architecture of Mobile Cross-Border Services Building Blocks

The growing trend of mobile services usage compared to desktop services necessitates the development of mobile-accessible e-government to cater to citizens’ growing digital needs. Secure and efficient solutions for strong authentication and cross-institutional data exchange are crucial in this context, particularly within the eID (electronic Identification) and SDG (Single Digital Gateway) domains. This work presents an advanced technical architecture developed as part of the H2020 mGov4EU project, which addresses these challenges by offering a comprehensive set of mobile-tailored building blocks that could serve as a basis when using e-Government. The proposed architecture consists of four building blocks: (1) eID Interoperability System, enabling mobile-based cross-border authentication; (2) Digital Wallet System, providing a user-friendly platform for citizens to manage their eID credentials and (SDGR) evidence; (3) SDG Interoperability System, enabling efficient cross-border data exchange and user-authorization access point; and (4) eSignature Interoperability System, ensuring secure and efficient creation of electronic signatures. Integrating these building blocks, the mGov4EU project enhances the baseline of e-Government in a mobile environment.
