A novel method to support user's consent in usage control for stable trust in E-business

Abstract

In the recent Web environment, the key issue is not who can use the resource, but how to control the usage of resources. Usage control (UCON) is a consolidate solution for this problem. UCON can be applied to solve existing authorization problems and support finer-grained control than any other methods. However, there are many situations in e-business and information systems in which the user consent is needed. For example, a contents provider should obtain the consent of the originator in order to modify digital contents. With this trend, the consent is suggested as a new issue that can establish trust in e-business. Unfortunately, the current UCON model does not support user consent. In this paper, we propose a novel method to control user consent in UCON model. We modify the authorization model of the UCON model to support consent handling and discuss the administration of proposed model. The proposed method extends the coverage of UCON model in security area. It also provides a solution for trust relationships on e-Business and individual privacy protection. © Springer-Verlag Berlin Heidelberg 2004.
