The Digital Car Passport

The automotive industry to build the digital car passport
Learn how The Blockchain Group and Eniblock in conjonction with IRT SystemX federated big names of the automotive industry to build a blockchain-based trustful car data platform.
Context
According to the FIA (Fédération Internationale de l’Automobile), more than 15% of vehicles circulating in Europe were subject to mileage frauds in 2018. This impacts the entire automobile industry negatively.
On the second-hand market, car re-sellers suffer from price devaluation and car buyers incur higher risk due to this breach of trust.
Insurance companies are struggling to evaluate the risks of breakdowns, and repair agents don’t have the correct information to work efficiently.
The lack of reliability and traceability on the vehicle life cycle data also hinders all service providers in the development of new services such as predictive maintenance or personalized insurance.
The Challenge
Bring together the automotive players to create a Connected Vehicle Passport that securely tracks and certifies all maintenance and upkeep data.
Today The Digital Car Passport project is supported by a consortium of companies in the automobile industry and insurance – including PSA, Mobivia, COVEA (MAAF, MMA, GMF), Matmut, Crédit Agricole Pacifica, Inter Mutuel Assistance.
List of consortium members
“The reflection on data sharing, its articulation between free competition and cooperation between the different actors brings a totally new and conquering vision for the whole automotive industry. This is why I support this very interesting project for the automotive industry, our economy and our sovereignty.”
Laure de La Raudière, Deputy of Eure-et-Loir French Department
The solution
A trusted automotive data platform based on the Tezos blockchain, which will make it possible to issue and manage an NFT representing the vehicle and all the data that characterise its life cycle: administrative data, usage data, maintenance data, etc. – data that is already accessible, but in a fragmented manner.
Vehicle traceability
Dematerialised invoices
Innovative customer service
Transparency and accountability
Obstacles to better use of valuable data
The vehicle’s maintenance record suffers from several weaknesses:
- Information registered in maintenance record is not digitized.
- Lack of trust on mileage claims on the second-hand market.
- Lack of trust about maintenance and upkeep on cars when re-selling.
- The car manufacturer has no visibility on interventions outside its network.
- Maintenance record information is not shared with insurers or other service providers.
- Some cars declared as wrecked go back on the road.
Make reliable data accessible to all companies within the consortium
Our ambition is to develop a blockchain-based system that creates a secured and accurate maintenance record for the lifecycle of each car:
Create a Car Passport
Share car management information
Develop new services
A platform designed for industry collaboration
Eniblock overcame several technical challenges:
Network incentives: Effective collaboration relies on alignment of interest and well-designed incentive schemes. We have set a dual token economy, pegged to the Euro, in order to incentivize data sharing amongst the stakeholders (PCC_token) and enforce fair governance and repartition of costs and benefits amongst the consortium members (PCC_gold token).
Reliability: The system is fed with manual input of data into the shared ledger by different members of the ecosystem. In order to maximize data collection, and hence optimize data valuation, we have introduced the notion of quality index attached to each source. All events and measures recorded in the blockchain will always be associated to this quality index.
Confidentiality & Dynamic Access Control: Information on a Blockchain is accessible among all its participants. However, some critical data fields are not meant to be shared widely. Moreover, these access rights have to be updatable. We have proposed a new on-chain protocol based on cryptography to implement dynamic access control.
RGPD compliance: Private information such as the vehicle identification number or its owner’s identity cannot be stored on the Blockchain according to the CNIL (French data protection authority). We have hence developed a protocol to match on-chain and off-chain data.
Performance & Data market performance: In order to increase performance of the queries within the data marketplace, we have built the data pipeline using a Lambda architecture, designed to handle massive quantities of data by taking advantage of both batch and stream-processing methods.
Interoperability & Integration: the system has to interact with the IT systems of PSA Groupe as well as that of all the other consortium members.
« This project is very ambitious as it lays the foundations for a sovereign reference architecture for the automotive industry.”
Abdelkrim Doufene, Directeur Stratégie et Programmes de l’IRT SystemX
New horizons for car owners and the automotive industry
We have demonstrated how to make existing markets more reliable and have opened up to new opportunities by building the grounds for a large, secure, and fair market data platform.
Information that was previously collected and stored in a silo by each market player, can now be shared in a collaborative approach, allowing all players to build new customized added-value services.
The blockchain architecture ensures the security and sovereignty of the data collected and allows an efficient and fair re-distribution of the value created using tokens.

The outcome
Validation of a common product vision (POC) and publication of a white paper that define the roadmap to lead the consortium : “Passeport du Véhicule Connecté, bénéfices de la Blockchain”.
