The patent is aimed at the development of ‘in-field authentication of autonomous electronic devices’ to enable deliveries securely.
The patent officially states,
“[i]n exemplary embodiments, two autonomous electronic devices, such as delivery drones or household autonomous robots, can authenticate each other using embodiments of security procedures described herein.”
The patent entitled as, “Systems, Devices, and Methods for In-Field Authenticating of Autonomous Robots”, was actually filed in January 2018 by Walmart. The system would enable multiple autonomous robots and drones for being incorporated in it’s supply chain. Blockchain will be used for the secure authentication devices on wireless signals.
As per the patent, blockchain deployment would be crucial for recording authentication signals and data, which is the primary target for hackers.
“Updates to the blockchain may comprise authentication signals or identification information, and one or more nodes on the system may be configured to incorporate one or more updates into blocks to add to the distributed database.”
Interestingly, Walmart has been actively applying for patents on blockchain related projects in U.S.A from last year. As per Investopedia, this move by Walmart seems to originate from their need to keep pace with its competitors.
One of the many patents Walmart files recently, one such example arises from its patent for managing smart appliances via blockchain. It would enable users to customise accessibility and control features on smart appliances.
This year July, The retail giant also published a patent for a blockchain enabled delivery system which would render the delivered items safe until the purchaser signs it off and collect.
