Claim 9:
10. A physically activated device authorisation method to control device access to a wireless network, wherein the system comprises a DHCP server coupled with an authorising device and a verifying device through a distributed ledger infrastructure;
wherein the DHCP server forms part of a wireless network and is adapted to:
receive a preconfigured record of Wi-Fi enabled devices that previously sought permission to join the wireless network;
replace the record with a further updated amended record on its receipt from the verifying device;
detect an identifier of a first Wi-Fi enabled device on its entering the range of the wireless network;
interrogate the record to find an entry with an identifier that matches that of the first Wi-Fi enabled device;
grant permission to the first Wi-Fi enabled device to join the wireless network in the event a first and second indicator in the matching entry both have a first value, and otherwise refuse the first Wi-Fi enabled device permission to join the wireless network;
add a new entry for the first Wi-Fi enabled device to the record in the event a matching entry is not found therein, to create an amended record, wherein the new entry in the amended record comprises the first and second indicators both of which are set to a second value;
share the amended record with the authorising device; and
wherein the authorising device is adapted to:
request and receive an input from a first user on receipt of the amended record; and
update the first indicator in the new entry to the first value in the event the first user's input is received within a first preconfigured time interval, to thereby create an updated amended record; and share the updated amended record with the verifying device; and otherwise deny the first Wi-Fi enabled device permission to join the wireless network;
wherein the verifying device is adapted to:
request and receive an input from a second user on receipt of the updated amended record;
update the second indicator in the new entry to the first value in the event the second user's input is received by the verifying device within the second time interval, to thereby create a further updated amended record; share the further updated amended record with the DHCP server; and otherwise deny the first Wi-Fi enabled device permission to join the wireless network.
