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： A packet intrusion detection rule simplification apparatus and method and an intrusion detection apparatus and method are provided. Test conditions of at least one intrusion detection rules are rearranged based on test items, and the same test conditions for the same test items are grouped. Group rules having a connection structure of the test conditions are generated so that the test items and orders of the intrusion detection rules are satisfied. A common rule consisting of test conditions existing at the test start positions in the connection structure of the group rules is generated. Next, packet intrusion detection is performed by using the common rule, and the packet intrusion detection is performed by using the group rules. According, it is possible to reduce a load involved in the intrusion detection process by using the grouped and simplified intrusion detection rules.
