Process Authentication through Blockchain: Three Case Studies

Il lavoro introduce le nozioni di gemello digitale e di autenticazione per un processo cyber-fisico sufficientemente generico, illustrando attraverso dei casi di studio concreti come implementare l'autenticità di processo grazie a concetti e strumenti utilizzati nel contesto delle tecnologie a registro distribuito.

In this work, we elaborate on the concept of process authenticity, which intuitively corresponds to the validity of all process steps and their proper binding. It represents the most exciting forefront of distributed ledger technology research concerning the primary challenge of reliably connecting distributed ledger networks to the physical context it must operate. More in detail, the paper describes a novel methodological approach to ensure the authenticity of business processes through blockchain and several security mechanisms applied to the digital twins of the actual processes. We illustrate difficulties and opportunities deriving from implementing process authenticity in concrete case studies in which we were involved as software designers belonging to three critical application domains: document dematerialization, e-voting, and healthcare.
