A National Mobile Identity Management Strategy for Electronic Government Services

The purpose of electronic government (e-Gov) programs is to promote government transparency and improve interactions with its citizens. One of the strategies used by governments for the development and enhancement of e-Gov services is the adoption of a Mobile Identity Management (IdM) System. In this context, this paper aims to describe a Mobile eID solution for a Brazilian IdM Strategy. Our proposed solution focus on security, privacy, and usability using FIDO UAF, TEE, and SAML standards. A prototype was developed and evaluated through functional test cases and an user usability satisfaction questionnaire. The results showed our proposed mobile eID system contributes more to user privacy than the currently e-Gov services. However, we observed in the experiments that usability could be affected when the user does not understand alert messages.
