Provided is a system for automatically generating 3D roads in a virtual environment based on precise road map data, the system including: a map data pre-processing unit configured to perform a pre-processing operation with respect to data of each layer constituting a precise road map; a roadway generation unit configured to generate a roadway by extracting roadway perimeter data based on driving path links; a shoulder generation unit configured to generate a mesh between a curb of a sidewalk which connects a border of the sidewalk and a border of the roadway, and the roadway; a sidewalk and bike road generation unit configured to generate a sidewalk and a bike road; and a road surface marking generation unit configured to generate a mesh for displaying lanes, crosswalks, and road surfaces on a road.

Provided is a deepfake detection model training system and method. A deepfake detection model training method according to an embodiment includes: combining a training dataset by using real face images, fake face images, and enhanced face images; and training a deepfake detection model by using the combined training dataset, and the deepfake detection model is a deep learning network model that classifies input images as a real class, a fake class, and an enhancement class. Accordingly, the deepfake detection model may classify even enhancement face images which are widely used recently, so that an error of falsely detecting an enhancement face image as a fake face image may be prevented.

Provided are a method and device of performing time synchronization. Delays and offsets are calculated through a messaging process in which a coordinator transmits a Sync message to one or more followers, the followers transmit Delay_Req messages to the coordinator in response to the Sync message, and the coordinator receiving the Delay_Req messages transmits a Delay_Resp message to the followers, and time synchronization is performed on the basis of the delays and offsets. Even when a plurality of followers are connected, the number of times PTP messages are transmitted is reduced by broadcasting the Sync message and/or the Delay_Resp message of the coordinator at once. Also, a transmission bandwidth occupied by PTP messages is reduced by performing PTP messaging using symbols that have significantly shorter lengths than existing PTP messages.
