Abstract:
When discussing the security of e-government applications one of the most crucial aspects is the identification of the users (aka citizens). On the one hand, the authorities and the users want to be sure beyond doubt that a certain action or record is related to the correct individual. On the other hand users do not want to have their actions or data in different domains (like health-care, taxes, register of residents, legal authorities) being linked to each other by the authorities. In this paper, we propose an efficient mechanism, which guarantees both, unique identification and inter-domain privacy protection. First of all, the proposed scheme is a replacement for the domain-specific citizen identifier defined by the Austrian authorities, but the scheme may be used as well in other scenarios, depending on unlinkable and unique identifiers.
