Mobile Identity Management

In this paper we review the state-of-the-art in Mobile Identity Management and discuss its implications for the emerging ubiquitous computing systems. We start by establishing the concept of identity in the digital context and then proceed to discuss the emerging field of digital identity and mobility. We identify the benefits of mobile identity management both for the consumer and for service providers. Next, we discuss the implications of Mobility Identity Management for the mobile business value chain. The limitations as well as the opportunities created by the introduction of mobile identity enabled services for collaborative, federated service provision across the value chain and its effect on market dynamics are the subject of the following sections leading to the introduction of a mobile identity management capability maturity model. Finally, we discuss the importance of Mobile Identity Management in the emerging field of ubiquitous computing and some possibilities for innovation in this context
