UASs (unmanned aircraft system) or drones, as they are known in common rather than legal parlance, can easily cross physical barriers. As drone use increases, both for commercial applications and for recreational purposes, new challenges are emerging with regard to privacy and information security.
Millions of drones are estimated to have already been sold worldwide; tens of millions are expected to be out-there by 2020. As with any easily available new technology, criminals are early innovators, for example getting drugs across borders and mobile phones into prisons; here existing laws are being broken. However, drone operators who wish to remain within the law, need to be aware of evolving rules.
