Abstract: An apparatus for detecting a malicious app. The apparatus may include a collector to collect a mobile app, a static analyzer to extract basic information from the collected mobile app, analyze the basic information of the extracted mobile app, and generate a call flow graph (CFG) of the mobile app, a dynamic analyzer to execute the collected mobile app, expand the CFG of the mobile app, generated by the static analyzer, to a dynamic action-based CFG, and determine a similarity between the expanded CFG and a flow graph that performs a malicious action, and a malicious app determiner to determine whether the collected mobile app is malicious by analyzing the basic information, the CFG, the call flow graph, and the similarity.

Abstract: There are provided an apparatus and method for tracking temporal variation of a video content context using dynamically generated metadata, wherein the method includes generating static metadata on the basis of internal data held during an initial publication of video content and tagging the generated static metadata to the video content, collecting external data related to the video content generated after the video content is published, generating dynamic metadata related to the video content on the basis of the collected external data and tagging the generated dynamic metadata to the video content, repeating regeneration and tagging of the dynamic metadata with an elapse of time, tracking a change in content of the dynamic metadata, and generating and providing a trend analysis report corresponding to a result of tracking the change in the content.

Abstract: A technology for allowing anyone to easily create interactive media capable of easily recognizing a user interaction by using a stored image is provided. A system according to the present invention includes an image reconstruction server, an image ontology, and an image repository. The image reconstruction server includes an image reconstruction controller, a natural language processing module, and an image search module. The image reconstruction controller of the image reconstruction server receives a scenario based on a natural language from a user and searches for images desired by the user by using the natural language processing module, the image search module, and the image repository. The natural language processing module of the image reconstruction server performs a morphological analysis and a syntax analysis on the scenario input by the user as a preliminary operation for the search of the image ontology. The image search module of the image reconstruction server automatically generates an ontology search query sentence, such as SPARQL, by using a result of natural language processing, and searches the image ontology by using the generated query sentence.
