We base our research on Roger's diffusion of innovation theory, and derive generic factors influencing the diffusion of federated identity management solutions. To validate our model and investigate specific contributions of parameters in specific usage scenarios, we investigate market success of federated identity management systems. We examine several application scenarios in the fields of e-business, Web, and e-government.enText/Conference Paper1617-5468
