Abstract: Aspects of the invention relate to methods of authenticating a user and user authentication systems. The method comprises classifying an image of the user as authentic or non-authentic by: identifying a separation vector between a user image characteristic vector and a hyperplane generated by a machine learning algorithm; comparing the separation vector with a threshold value; and associating the user image with a classification value if the separation vector exceeds the threshold value. The user may be authenticated based on a classification decision informed by the classification value associated with the user image.

Abstract: A flight departure control system comprises a central departure control system and a plurality of local departure control systems arranged at or in proximity of individual airports. Passengers check-in for flights via the central DCS and for each passenger a passenger data message is created and sent to the local DCS to which the flight relates. On detection of a fault condition at the central DCS or in communications with the central DCS, the local DCS assume responsibility for flights departing from the airport at which they are located based on the received passenger data messages and unchecked-in passengers check-in directly with the local DCS.

Abstract: An apparatus and computerized method are provided for monitoring the positions of one or more aircraft. The apparatus comprises a first receiver configured to receive first aircraft position information, over a digital data link, from a first radio frequency source located onboard the aircraft at a first period, via one or more ground stations and a second receiver configured to receive second aircraft position information broadcasted from a second radio frequency source located onboard the aircraft at a second period, via one or more ground stations. The apparatus additionally comprises a third receiver configured to receive electronic geographical mapping data and a processor configured to receive the first and second aircraft position information, to filter the quantity of first and second aircraft position information to smooth the filtered information and then output the smoothed information such that it can be overlaid onto the electronic geographical mapping data.
