A Blockchain/Cloud Privacy Performance Comparison Using AHP Methodology: A Smart Road Case Study

The GDPR impacts on the design of information systems which process personal data, because it makes mandatory the adoption of the privacy-by-design and privacy-by-default principles. This compliance must be verified along all the design cycle, so that it must be considered as early as possible in the cycle, when alternatives are not yet detailed in the overall design and just general directions of the projects may be available. A comparison between alternatives should be performed, which can only have a qualitative nature, but which involves numerous factors, so a panel of experts is needed to obtained a reliable result. In this paper we propose a AHP-based evaluation approach to examine privacy-related features of alternative information system architectures in the early phases of the design cycle.
