Trust is crucial when a truster allows a trustee to carry out desired services. Regulatory authorities thus set requirements for organizations under their jurisdiction to ensure a basic trust level. Trusted auditors periodically verify the auditee’s compliance with these requirements. However, the quality of the auditees’ compliance and the auditors’ verification performance often remain unclear and unavailable to the public. In this work, we examine the regulations of Identity and Access Management (IAM) and identify typical patterns. We enhance these patterns to include trust measurements for the auditee providing services and the auditors verifying compliance. We demonstrate the feasibility of this approach for an application utilizing decentralized blockchain technologies and discuss the implications, potential, and benefits of this architecture.
