AISS4SA

The AISS4SA project (AI-based Self-Sovereign Identity for Smart Access) focuses on creating a privacy-aware, decentralized digital identity framework tailored for smart living environments, including smart homes, smart communities, and smart working spaces. Coordinated by Politecnico di Milano, it addresses challenges in access management by leveraging Self-Sovereign Identity (SSI) and blockchain technologies.

The system allows users to manage access credentials to various services (e.g., smart homes, workplaces, and communities) without relying on centralized authorities. It enhances privacy by using zero-knowledge proofs and distributed ledgers to authenticate users while ensuring minimal disclosure of personal data. The project also explores how to integrate these digital identities with existing physical and digital infrastructure.

The project is a multidisciplinary initiative developed within the 19th cycle of the Alta Scuola Politecnica (ASP), a joint program between Politecnico di Milano and Politecnico di Torino. As is customary for ASP projects, AISS4SA was carried out by a team of 6–7 students from diverse academic backgrounds, under the guidance of faculty tutors from both institutions.

AISS4SA is part of the Italian MUR-funded PNRR Extended Partnership “SEcurity and RIghts In the CyberSpace” (SERICS), under the NextGenerationEU initiative. It involves collaboration among academic institutions and industrial partners to test and validate its identity solution in real-world use cases.
