DID-IMP

DID-IMP is leveraging blockchain technologies to remove the need for a classical hierarchical structure with players like the Certificate Authority (CA) and the Registration Authority (RA). We replace these administrator-like trusted third parties (RA & CA) with a feeless blockchain smart contract. The blockchain is also used as a Certificate Store on which services providers can issue and manage revocable certificates and credentials. Such a lean architecture is especially well adapted for Internet of Things (IoT) Secure Automatic Data Sharing SADS. Indeed, SADS can be used in various ways to simplify and streamline data sharing processes, and to secure and trace data transfers. Some of the main use cases include connected cars, remote healthcare, cognitive cities or energy management. In a nutshell, we build a Trust Chain for IoT secure data sharing, bringing better traceability to data, securing their flow and allowing companies to reduce administrative overhead, save time and money, and offer a better protected data sharing experience for final customers. Indeed, users can retain ownership and control over their IoT data while granting access to specific parties through permissioned credentials. Additionally, our SADS-enabled solution can help to manage the flow of sensitive data and the compliance to the new European and Global regulations, thanks to the native traceability features provided by blockchain technologies combined with the process proposed by this DID-IMP project, which implies a traced blockchain transaction for each data transfer, also tracking the main regulatory characteristics of the data exchanged.

- Motivation for the project: DID-IMP, as a secure data automatic transfer system, is crucial in a trusted blockchain ecosystem to ensure data transfer integrity, to improve efficiency by automation and to increase scalability, handling increased loads and complex transactions without compromising security or performance.
- Generic use case description: As an IoT device fleet manager, the user wants to be able to control all the IoT devices he manages and for which he can create or revoke verifiable credentials. He also wants to have a status of the data that have been transferred or procured and to which other IoT devices.
- Essential functionalities: The essential functionalities are the following: create and delete IoT device account, associate IoT device account with fleet (or modify this association), create and delete verifiable credentials to control secure data flows, audit data transfers.
- How these functionalities can be integrated within the software ecosystem: DID-IMP answers the specific needs of secure automatic data transfers for IOT devices in the Trustchain software ecosystem. It can be integrated into any other solution.
- Gap being addressed: IoT devices often require a decentralized identity solution because they need to securely interact with other devices and systems without relying on a central authority or intermediary. Indeed, IoT devices may be autonomous, have limited processing power or memory, and operate in environments where connectivity is intermittent or unreliable.
- Expected benefits achieved with the novel technology building blocks: Our IoT-specific SADS solution brings numerous benefits tailored to the unique needs and challenges of IoT environments. These benefits enhance the overall operational effectiveness of IoT systems. The key advantages are enhanced security, data Integrity and privacy, automated management and remote monitoring and control.
- Potential demonstration scenario: A potential demonstration scenario would be photovoltaic solar panels data transmission to a decentralized energy community. In this use case, the solar electricity quality would be ensured by DID-IMP secure automatic data transfer between the solar panel management system and the energy community. This would allow to certify the electricity origin.
