A system and methods are provided for determining a vehicle action during a phantom projection attack, including processing a received image to identify a traffic object, and creating from the received image multiple processed images that are applied to respective neural network (NN) models. Latent representations of the multiple processed images from each of the NN models are then fed to a combiner model trained to determine whether the latent representations indicate a phantom projection attack, and, responsively to a determination of a phantom projection attack, issuing a phantom projection indicator.

Methods for detecting phantom projection attacks against computer vision algorithms

A signature verification system, which comprises a plurality of worn devices of signing users, each provided with one or more motion sensors, and a processor for receiving motion signals from the sensors, the processor is adapted to define a set of features that describe a signature and distinguish one signature from another; perform a training phase by obtaining motion signals from one or more motion sensors of the worn devices; training a machine learning classifier using the instances and labels; obtain motion signals from motion sensors of the a worn device, the motion being of an allegedly genuine signature of one of the users; scale and domain transform the allegedly genuine signature; calculate values of the features describing the allegedly genuine signature with respect to scaled and transformed reference signatures of the one of the users; and apply the trained classifier on the feature values, thereby classifying the allegedly genuine signature as genuine or forged.

A system and method for identifying if a drone is illegitimately video streaming a location, object or person. An interceptor intercepts radio transmissions and identifies if a radio transmission is an FPV video transmission. A watermarker is used for emitting a periodic physical stimulus at a given frequency for a given duration. The system then verifies if there is a correlation between the video transmission and the periodic physical stimulus; and issues a privacy invasion attack notification if such a correlation is determined between the video transmission and the periodic physical stimulus.
