Disclosed is a method of obfuscating a Controller Area Network (CAN) message performed by a first computing device including a processor, the method including: obtaining a first index from a first input value corresponding to a first time point by using an index output algorithm; determining a first CAN ID of the first computing device corresponding to the first index based on a predetermined CAN ID table; and generating a first normal CAN message including the first CAN ID and first normal data.

Obfuscation method for controller area network message

A method for compressing time series data includes: reading original data including time series data; measuring a unit of the original data; determining a threshold for determining a range allowing for a difference between compressed data and the original data; performing longest distance downsampling to preserve an abnormal point of the original data; storing a start point and an end point of the original data; performing drop-out on the longest distance downsampling result, wherein the drop-out is not performed for the start point and the end point; and if the number of values of the original data is smaller than &#x3b1; times the original data length, storing at least one of the values of the original data as a reference point, wherein &#x3b1; is a real number having a value between 0 and 1.

Method for compressing and restoring time series data

A method and an apparatus for predicting a collision are provided. The method includes calculating, by a controller, a driving trajectory of the subject vehicle based on a yaw rate using driving information of the subject vehicle. In addition, the controller is configured to calculate a driving trajectory of a target vehicle for a predetermined period of time that uses driving information of the target vehicle that includes information from an imaging device, configured to obtain a front image, and radar sensors installed on a plurality of locations. Further, the method also includes predicting classified collision types by analyzing a collision possibility between the subject vehicle and the target vehicle based on the driving trajectory of the subject vehicle and the driving trajectory of the target vehicle.
