The American giant of automobile production General Motors (GM) has filed a blockchain patent for a solution for the management of data from autonomous vehicles. The patent application was published by the U.S. Patent and Trademark Office (USPTO) on 29 November.
GM's application, submitted on May 25, 2017, outlines a system for using the blockchain to provide "secure" and "robust" data distribution and an interoperable exchange between multiple automated vehicles and other entities, such as municipalities, regional authorities and public facilities.
While autonomous vehicles in particular require "high levels of integrity" for "data on temporal events", the application emphasizes that a blockchain system is "desirable" even for semi-autonomous and non-autonomous vehicles.
Like storage profiles, blockchain "realizes [the] enterprise "to" allow a trusted consensus of trust in which all transactions can be verified in the future by the participants in the blockchain exchange without compromising privacy. "
The patent proposes that a blockchain system can be used to share information in relation to a series of practical needs, resources and legal documents. These include navigation of the route, availability of charging and refueling services, determination of the validity of permits and licenses for vehicles operating as "hack, taxi or other rental services", as well as "maintenance of balances for […] expenses related to tolls, parking, car washes and access to other paid services. "
As a precaution, the document warns that it would be better to "implement a blockchain bag to push only approved, verified and secure location information to the occupants of an autonomous vehicle".
GM's filing indicates that the use of the blockchain may further extend to allow interaction with traffic management systems and highways and autonomous car users, in the form of an online ledger booklet or cloud for access and distribution [different types of ] information from the National Highway Transportation Safety Administration (NHTSA). "
An additional type of data for entry into the blockchain system could relate to the "behavioral skills" of autonomous vehicle users, with an online ledger blockchain created for information relating to "vehicle actions, driver behavior and driver follow the traffic rules ".
This summer, GM joined BMW, Ford and Renault as new members of the Mobility Open Blockchain Initiative (MOBI), an important joint venture with over 30 participants including Bosch, Hyperledger, IBM and IOTA.
In June, IOTA and Volkswagen demonstrated a theoretical verification (PoC) for autonomous cars, which uses the Tangle-oriented IoT (Internet of Things) IoT architecture rather than a "traditional" blockchain.
