“…Trustworthiness has several interpretations, but one that seems to be well accepted is that it is related to the assurance the system will perform as expected (e.g., [1,13,15]). In this sense, trustworthiness can be presented as a more complex metric that builds on top of the operativeness metric, using a well defined methodology to select the actions tested in that metric.…”

Abstract. Transparency, a principle advocated by the General Data Protection Regulation, is usually defined in terms of properties such as availability, auditability and accountability and for this reason it is not straightforwardly measurable. In requirement engineering, measuring a quality is usually implemented by defining a set of metrics for its composing properties, but conventional approaches offer little help to achieve this task for transparency. We therefore review requirements for availability, auditability and accountability and, with the help of a meta-model used to describe non-functional properties, we discuss and advance a set of metrics for them. What emerges from this study is a better justified and comprehensive tool which we apply to measure the level of transparency in medical data-sharing systems.

“…We assume a requirement engineer has already elicited the goals of involved stakeholders based on domain knowledge. In the future, we will address these issues by a method for analysis of trustworthiness requirements using goal-oriented approaches [7]. Furthermore, the social aspects of trustworthiness will be given more attention.…”

“…The left side of Figure 1 shows the level of abstraction for trustworthiness and their influences on different levels of abstraction on the system-side (simplified SOA layers). The refinement of trustworthiness requirements on different abstraction levels with a combination of goal models and business process models is presented in our other work [7].…”

The trustworthiness of systems that support complex collaborative business processes is an emergent property. In order to address users' trust concerns, trustworthiness requirements of software systems must be elicited and satisfied. The aim of this paper is to address the gap that exists between end-users' trust concerns and the lack of implementation of proper trustworthiness requirements in software systems. We focus on the challenges of specifying trustworthiness requirements and integrating them into the software development process as business process models. This paper provides a conceptual model of our approach by extending Business Process Model and Notation (BPMN) for integrating trustworthiness requirements. Our proposed approach explicitly considers the trustworthiness of individual components as part of the business process models. We use an application example from the health care domain to demonstrate our approach.

Abstract:The trustworthiness of systems that support complex collaborative business processes is an emergent property. In order to address users' trust concerns, trustworthiness requirements of software systems must be elicited and satisfied. The aim of this paper is to address the gap that exists between end-users' trust concerns and the lack of implementation of proper trustworthiness requirements. New technologies like cloud computing bring new capabilities for hosting and offering complex collaborative business operations. However, these advances might bring undesirable side effects, e.g., introducing new vulnerabilities and threats caused by collaboration and data exchange over the Internet. Hence, users become more concerned about trust. Trust is subjective; trustworthiness requirements for addressing trust concerns are difficult to elicit, especially if there are different parties involved in the business process. We propose a user-centered trustworthiness requirement analysis and modeling framework. We integrate the subjective trust concerns into goal models and embed them into business process models as objective trustworthiness requirements. Business process model and notation is extended to enable modeling trustworthiness requirements. This paper focuses on the challenges of elicitation, refinement and modeling trustworthiness requirements. An application example from the healthcare domain is used to demonstrate our approach.
