LOCATION-BASED DATA ACCESS CONTROL

摘要

Particular functionality of an item of equipment (70) is enabled upon both a location condition and a personnel condition being satisfied. The location condition is tested for by obtaining current-location data (67) representing the current location of the equipment, and comparing the current-location data with authorised-location data representing a predetermined authorised location or locality for operation of the equipment functionality. The personnel condition is tested for by checking for the presence at or near the equipment of at least one person (77) fitting stored authorized-personnel data (42) that identifies specified person or persons, or a specified grade of person. The location and personnel conditions can be tested for at the equipment (70) or at a remote service system (40).
