"Seeing is not Always Believing": Detecting Perception Error Attacks Against Autonomous Vehicles
Jinshan Liu, Jerry Park
Abstract
Due to the great achievements in artificial intelligence, it is predicted that autonomous vehicles with little or even no human involvement will come to market in the near future. Autonomous vehicles are equipped with multiple types of sensors. An autonomous vehicle relies on its sensors to perceive its environment, and this sensory information plays a key role in the vehicle's driving decisions. Hence, ensuring the trustworthiness of the sensor data is crucial for drivers’ safety. In this article, we discuss the impact of <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">perception error attacks (PEAs)</i> on autonomous vehicles, and propose a countermeasure called LIFE ( <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</b> IDAR and <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">I</b> mage data <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">F</b> usion for detecting perception <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</b> rrors). LIFE detects PEAs by analyzing the consistency between camera image data and LIDAR data using novel machine learning and computer vision algorithms. The performance of LIFE has been evaluated extensively using the KITTI dataset.
