Blockchain-Based Privacy Preservation for 5G-Enabled Drone Communications

5G-enabled drones have potential applications in a variety of both military and civilian settings (e.g., monitoring tracking individuals demonstrations and/or enforcing social/ physical distancing during pandemics such as COVID-19). Such generally involve the collection dissemination (massive) data from to remote centers for storage analysis via 5G networks). Consequently, there are security privacy considerations underpinning drone communications. We posit leveraging blockchain facilitate preservation, therefore this article we review existing blockchain-based solutions after introducing architecture communications block-chain. also legislation regulations that need be considered design solutions, well identify challenges open issues will hopefully inform future research.
