Boeing filed a new patent that talks about aircraft manufacturing giant is looking at how blockchain can help protect in-flight GPS receivers. This is reported by the CoinDesk.
The application, released by the U.S. Patent and Trademark Office, the aircraft giant details an "onboard backup and anti-spoofing GPS system" that would be used if a plane's primary system becomes unreliable or nonfunctioning.
GPS "spoofing" is a practice by which counterfeit signals are used to effectively trick other receivers. Such attacks can be used to confuse a GPS receiver about the actual location of other objects. These simulated signals have been changed in such a way as to cause the recipient to misconstrue their location, considering it to be the one sent by the attacker. Because GPS systems work by measuring the time it takes for a signal to travel from satellite to receiver, successful spoofing requires that the attacker know exactly where his target is - so that the simulated signal can be structured with appropriate signal delays. GPS attacks can be extremely danger when aircrafts are the targets.
Blockchain data would be used as a backup record of information in the event that the anti-spoofing system detects potential danger.
The method further determines if the GPS signals, received by the GPS receiver, are spoofed GPS signals and, then, retrieves position data from the block-chain storage module if the GPS receiver is not receiving the GPS signals or is receiving spoofed GPS signals.

The backup would store environmental information received from the GPS, allowing it to act as a failsafe to prevent pilots from getting lost by providing all of the information a GPS normally would. The system can be applied to any type of vehicle, both manned and unmanned, according to the application.
The blockchaing data would store environmental information received from the GPS. It is designed to to act as a failsafe to prevent planes to lost in the air. The system can be applied to any type of vehicle, both manned and unmanned.
