Holistic Trust Design of E-Services

Abstract

As a central issue of modern e-services, trust has to be tackled early during the development phases. We present and compare, in this chapter, various works and methodologies that contribute to this aspect. A holistic trust design methodology that combines useful aspects encountered in the existing works is then described in detail. It is based on a systematic analysis of scenarios that describe the typical use of the e-service by using a trust analysis grid. The trust analysis grid is composed of 11 trust issue categories, which cover the various aspects of the concept of trust, and is used to guide the design of the computing system by analyzing and refining the scenarios, and providing hints at the suitability of technologies for the scenario. We illustrate this methodology in several examples.
