Apparatus and method for analyzing permission of application for mobile devices and detecting risk

Provided are an apparatus and a method that chooses an object to be preferentially controlled based on an accident risk degree and hazard and controls the chosen object. In the present invention, it is possible to choose and control a ship having high hazard calculated with trajectory prediction, current operation state information, and past history information under a traffic situation in which the ships are concentrated, by priority. The ship having high hazard is chosen by calculating and applying various history information including an accident record, an entry history of an operator, an aging degree history of the ship, and a steering feature history by using a collision risk on a real-time trajectory collision risk and past history information and different warnings are given during a control for each level.

Apparatus and method for choosing priority control object, and apparatus for controlling object

The present invention relates to an insider threat detection device and method which collects and analyzes a variety of information generated by insiders working for an organization, such as behaviors, events, and states of the insider, and detects an abnormal insider who may become a potential threat. According to the present invention, the insider threat detection method and apparatus analyzes information related to insiders using the correlation analysis method, and previously detects an abnormal sign of an insider who may become a potential threat to an organization, which makes it possible to protect the organization from attacks on systems inside the organization or seizure of important information inside the organization.

Disclosed are a method and apparatus for masking a privacy area of an image. The method for masking a privacy area of an image includes: detecting a privacy area required to be protected in an image; and performing masking on the image. An important area (a face area of a person, a number plate area of a vehicle, a window area of a house, etc.) detected from an image inputted through a CCTV camera can be effectively and easily encrypted, scrambled, decoded, and descrambled. Also, the position of the important area detected before or after the important area is scrambled can be maintained to be consistent without having to use a metadata file. In addition, a scrambling algorithm of the same key value can be applicable regardless of the size of the important area. As a result, the system efficiency can be enhanced by effectively protecting personal information compared with a CCTV-based video security system.
