A Novel Method for Video Surveillance System Safety

摘要

A secure method used by monitor system to prevent video attack is shown in this article. This method is based on FDM (Frequency-division multiplexing), FH (Frequency Hopping) and mutually verification. By the scheme, cheating video and interception of video can be avoided, the system can alarm automatically if video attacking happened. In this paper, how to use the technology to achieve the scheme is explained. This easier and more practical technique can improve the safety of analogue or digital monitor systems.
