What is Electronic Services

Information security is increasingly necessary between citizens and public services. In a nearby environment, such as cities, there are digital services and infrastructures that help improve our quality of life. Secure access to services must be regulated and offer trust to the user. Initiatives like the Regulation from European Union, (EU) N° 910/2014 of the European Parliament and the Council intend to favour solutions for problems like interoperability and cybersecurity. In this chapter, two European countries are considered so that implementations of the electronic identification, authentication, and trust services are presented and discussed. The main contribution is a description of relevant European projects, a first step necessary to propel further research on this topic. The chapter also presents the current challenges for the consolidation of the technology used and for the adaptation of the electronic services offered by public administration bodies to citizens.
