Competitive Compliance with Blockchain

Authentication is essential for sharing information in IoT and its secondary use with AI-capable machines. The aim is to support humans in optimizing risk of supply chains for industrial manufacturing and service provisioning in a timely manner. The ultimate aim is sustainability. The problem for deciding on authentication is probably imperfect information on compliance. Its asymmetric implications of the meaning of contracts for secure information sharing may cause vulnerability of data breach and misuse. A traditional way to avoid harm of that asymmetry requires authentic and consistent sharing of audit information on violation of a certification policy to a centralized audit intelligence. This information sharing is, however, subject to the problem of single point of failure of the centralized audit intelligence. With our work on Security by Design, we show a non-central approach of clarifying accountability to reduce the risk caused by asymmetric implications of the meaning of contracts on authentication. Our signaling and screening scheme SK4SC provides personal digital evidences on compliance to multilateral policies on using information or in other words on trustworthiness. Blockchains are used to realize their symmetric distribution while users share risk on accountability with competition on incentives in a privacy-enhancing manner. Customer relationship management with royalty points, e.g., for eGovernment with taxation, is an example for using SK4SC as digital platform.
