A methodology for designing trustworthy e-commerce applications

Trustworthy e-commerce applications are not easy to design. Currently, patches are periodically released to countermeasure trust issues that arise in e-commerce communities. In this paper, we propose a methodology for designing trustworthy applications that enables an application designer to model applications resilient to trust related threats early in the development life cycle. Such modeling requires understanding of the system data flow and how the different processes use the system data. Our methodology consists of two phases, namely, data flow trust model and trust mitigation model.
