Unauthorized user detection-device

System for detecting that unintended user on distribution side is watching in streaming distribution

Overview

　In conventional systems, processing must be performed on the user's computer in order to understand the user's viewing status, resulting in the fatal problem of being interrupted by a malicious user. In this system, it is possible to understand the viewing status on the network under the control of the distribution side, and since the contents of the communication data are not directly referenced, it is a safe method for the user.　
　Specifically, it is a method to determine the degree of similarity by the correlation coefficient between a specific video or audio pattern and a previously recorded pattern based on the change in the output pattern of traffic data provided as standard equipment in the router.
