摘要： A method and apparatus for generating discriminant functions for distinguishing obscene videos by using visual features of video data, and a method and apparatus for determining whether videos are obscene by using the generated discriminant functions, are provided. The method of generating discriminant functions includes: creating a first frame set by extracting a predetermined number of frames for each video data unit from a group of video data classified as obscene or non-obscene, and creating a second frame set by selecting the frames; generating a frame based discriminant function by extracting visual features of frames of the second frame set, and then generating a first discriminant value by determining whether each frame of the first frame set contains obscene video data; generating a group frame based discriminant function by extracting visual features of a group of frames of the first frame set, and then generating a second discriminant value by determining whether the frames of the group contain obscene video data; and generating a synthetic discriminant function by using the first and second discriminant values as a representative value of the video data. Accordingly, obscene video data stored in a computer system can be automatically and accurately distinguished.

摘要： A method and a device for discriminating an obscene video using a time-based feature value are provided. The method includes: forming a first time-based flow of predetermined feature values varying with the lapse of time from one or more types of videos which are normalized with a first time interval; extracting a feature value varying with time from an input video of which obsceneness is to be determined and which is normalized with a second time interval, and forming a second time-based flow of the extracted feature value; and determining the obsceneness of the input video by calculating a loss value between the first time-based flow and the second time-based flow. The videos such as movies and dramas in which many persons appear have different obscenity characteristics from that of pornography, so it is possible to enhance reliability in determination of obsceneness.

摘要翻译： 提供了一种使用基于时间的特征值来辨别淫秽视频的方法和设备。 该方法包括：从以第一时间间隔归一化的一个或多个类型的视频形成随时间流逝而变化的预定特征值的第一时间流; 从要被确定淫秽的输入视频中提取随时间变化的特征值，并且以第二时间间隔被归一化，以及形成所提取的特征值的第二基于时间的流; 以及通过计算所述第一基于时间的流和所述第二时间流之间的损失值来确定所述输入视频的猥亵性。 许多人出现的电影和戏剧等视频与淫秽色情有不同的淫秽特征，因此有可能提高羞辱性的判断力的可靠性。

摘要： An adaptive security policy based scalable video service apparatus includes a video streaming server, an adaptive security policy server and a terminal. The video streaming server receives a service demand via a network and generates an encrypted streaming data. The adaptive security policy server analyzes a media structure and the service demand, by using a service profile received from the video streaming server, so as to generate a security policy description. The terminal generates and transmits the service demand to the video streaming server or the adaptive security server, obtains the encrypted streaming data from the video streaming server and decrypts the encrypted streaming data for playback, storing and retransmission.
