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.

Apparatus for training recognition model, apparatus for analyzing video, and apparatus for providing video search service

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.

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.

Disclosed herein is an object-tracking apparatus and method in the environment of multiple non-overlapping cameras. Color rendering values are divided into a plurality of sub-color regions. RGB pixels of objects in a first image and a second image are converted into first hue values and second hue values, respectively. The first hue values are assigned to corresponding sub-color regions, and then a first color histogram is generated. The second hue values are assigned to corresponding sub-color regions, and then a second color histogram is generated. An area of the first color histogram is extended. It is determined whether the second color histogram is included in the extended area of the first color histogram. It is determined that the object in the first image is identical to the object in the second image if the second color histogram is included in the extended area of the first color histogram.

A privacy region-masking device of an automobile black box system includes a masking region configuration module for constructing a masking region on an internal image of a vehicle and a key management module for creating and managing a masking key which is used for masking the masking region on the internal image of the vehicle. The privacy region-masking device further includes a masking execution module for masking the masking region on the image using the masking key, thereby generating a masked image adaptable to protect the privacy of a passenger.

Disclosed are a system and method of sharing intrusion detection information detected at different networks and tracking the intrusion, to thereby defense against the intrusion on a network to which an intruder belongs, and a computer-readable medium storing a program for implementing the above method therein. The system detects an intrusion through the analysis of an input packet, adds information associated with the intrusion into the packet, creates an active packet and transmits the active packet to an address of an intruder, which transmitted the packet. Thereafter, the system tracks the intrusion, for all routes through which the intruder passed based on the active packet, and filters the packet associated with the intruder for the isolation thereof.
