Stream Media Steganalysis Based on Sliding Window Detection

Information hiding in network protocols & streaming media and its detection have been hot research points in recent years.In this paper,the problems of real-time steganalysis in the network environment are studied and a real-time detection model is put forward.The focus is on the sampling method based on sliding window.Extensive experiments reveal the relationship between the length of sliding window and the accuracy of detection.The results give insight into the key problem of how to choose a better window length to gain a balance between detection accuracy and time complexity.
