Abstract: Disclosed herein is an apparatus for analyzing a video shot. The apparatus includes at least one program, memory in which the program is recorded, and a processor for executing the program. The program may include a frame extraction unit for extracting at least one frame from a video shot, a shot composition and camera position recognition unit for predicting shot composition and a camera position for the extracted at least one frame based on a previously trained shot composition recognition model, a place and time information extraction unit for predicting a shot location and a shot time for the extracted at least one frame based on previously trained shot location recognition model and shot time recognition model, and an information combination unit for combining pieces of information, respectively predicted for the at least one frame, for each video shot and tagging the video shot with the combined pieces of information.

Abstract: An apparatus and a method for an attack source traceback capable of tracing back an attacker, that is, an attack source present behind a command and control (C&C) server in a cyber target attack having non-connectivity over a transmission control protocol (TCP) connection are disclosed. The apparatus for the attack source traceback includes: a server information extracting unit detecting an attack for a system, which is generated via a server to thereby extract information on the server; a traceback agent installing unit installing a traceback agent in the server based on the information on the server; and a traceback unit finding an attack source for the system by analyzing network information of the server obtained by the traceback agent.

Abstract: Disclosed herein are an apparatus and method for generating evidence video. The apparatus includes a video object indexing unit, a video object search unit, and an evidence video generation unit. The video object indexing unit recognizes an object by storing and analyzing videos received from multiple surveillance cameras, extracts the features of the recognized object, and then generates object metadata. The video object search unit compares received search conditions with the object metadata, and then outputs search results, including the feature information of at least one object, which corresponds to the search conditions. The evidence video generation unit generates an evidence video by aggregating only videos including a specific object selected from the search results.
