Claim 0:
1. A physically activated device authorisation method to control device access to a wireless network, wherein the method comprises the steps of:
preconfiguring the values of a first time interval and a second time interval for receipt of a user input to an authorising device and a verifying device respectively;
detecting by a DHCP server forming part of the wireless network an identifier of a first Wi-Fi enabled device on its entering the range of the wireless network;
interrogating, a record of Wi-Fi enabled devices that previously sought permission to join the wireless network to find an entry with an identifier that matches that of the first Wi-Fi enabled device;
checking the values of a first and second indicator in a matching entry in the event a matching entry is found in the record;
granting by the DHCP server, permission to the first Wi-Fi enabled device to join the wireless network in the event the first and second indicator in the matching entry both have a first value, thereby indicating that a Wi-Fi enabled device corresponding to the matching entry had been previously granted permission to join the wireless network and otherwise refusing the first Wi-Fi enabled device permission to join the wireless network;
adding a new entry for the first Wi-Fi enabled device to the record in the event a matching entry is not found therein and thereby creating 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;
sharing the amended record with an authorising device;
requesting a first user for an input to the authorising device on its receipt of the amended record;
updating the first indicator in the new entry to the first value in the event the first user's input is received by the authorising device within the first time interval to thereby create an updated amended record; sharing the updated amended record with the verifying device; and otherwise denying the first Wi-Fi enabled device permission to join the wireless network;
requesting a second user for an input to the verifying device on its receipt of the updated amended record; and
updating 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; sharing the further updated amended record with the DHCP server and replacing the record with the further updated amended record; and otherwise denying the first Wi-Fi enabled device permission to join the wireless network.
