Managing Information Assurance in Subscription-Based Financial Services

Abstract

This chapter reviews the main types of access control mechanisms that can be used to govern subscription-based financial services. The overall performance of these mechanisms is analyzed with respect to several important features of subscription-based financial services. Namely, the chapter analyzes the impact of the following features: (1) the number of clients/ subscriptions can be potentially large; (2) the number and types of subscriptions offered by a provider varies in time; (3) subscription terms may change; and (4) subscriptions terms may take into account mutable information. Furthermore, the chapter presents in detail one mechanism that achieves good performance.
