This recently published patent from car maker Jaguar Land Rover states car-mounted cameras will use facial recognition and gait analysis to identify drivers as they approach their vehicles allowing them to unlock their vehicles without the need to carry keys. This move is an attempt by the manufacturer to combat car thefts. Using gait analysis ensures thieves could not fool the system by holding up pictures of the owner’s face.
The patent application states: ”The user of the vehicle must carry out a registration process which requires them to record a still image of their face and a moving image such as a hand gesture or their gait as they approach the vehicle.”
Multiple drivers of a vehicle (i.e. family members and friends) can register their personal characteristics, allowing them to unlock the vehicle. If the owner sells the vehicles their details can be erased and new user details installed.
