NASA considers using block chain technology to ensure the safety and privacy of flight data

However, from January 1, 2020, the United States will launch another new monitoring system called ADS-B, which will disclose status information such as the identity and location of aircraft.

The good news is that with the open source licensed block chain framework, we can re-realize the privacy and anonymity of flights, provide safe and effective air traffic services and operational support, or communicate with other authorized entities.

Reisman outlines a prototype of "Aircraft Block Chain Infrastructure" (ABI), which is based on Hyperledger Fabric (one of the projects hosted by the Linux Foundation) and smart contract technology, allowing open control and authorization, or private data sharing.

As mentioned in the study, many block chain systems currently deployed allow some members to conduct private transactions while coexisting with restricted members of the same block chain network.

The system allows members to define one or more channels, isolate peers into subnets, and create private ledgers. Accounts for each channel can only be accessed by peer members.

The organization (or entity) that manages the channel must first approve the membership of each peer in the channel. Requests from the client are routed to the specified channel to run the smart contract deployed on that channel.

The final result needs to be recognized and verified before it can be updated in the channel's ledger. These channels will then be used to complete private transactions to ensure the security of aircraft status information such as altitude, longitude and latitude in dedicated channels.

As for non-confidential information such as aircraft flight plans (take-off place, destination, route, etc.), it can still be published on public channels for public access by all approved members.

Interestingly, last year, NASA donated $330,000 to a professor at Akron University to study space debris auto-detection technology based on the Ethernet block chain network.
