Improved SVM Algorithm and its Application in Media Information Security System

With the development of network, more and more broadcast television information transfers from simulation to digit, and increasingly transmits in the network. Therefore the media information security question is imminent, is a pending issue. This paper is from the perspective of intrusion detection to consider security issues. This paper adopts the technology of text classification, designing an improved SVM algorithm to identify intrusion information. The experiment results show that this method has high classification precision and efficiency.
