Abstract: Eavesdrop technology involves the national confidential information security. As the representative of covert visible light information transmission, visible light communication eavesdrop technology has the characteristics of strong elusiveness, being difficult to detect and protect and wide distribution of LED lights, which will lead to huge threats to information security. This paper first describes research status of visible light communication eavesdrop technology at home and abroad. The technical principles and key technologies are also introduced. Then through the analysis of characteristics of visible light communication eavesdrop technology, it shows that the technology will be a serious threat to the national information security. According to the security problems of this technology, the paper proposes that relative organizations should take measure to strengthening awareness and employ visible light communication eavesdrop detection device.

Key words: eavesdrop, covert visible light information transmission, visible light communication, visible light communication eavesdrop, visible light communication eavesdrop detection

摘要： 语音监听技术涉及到国家保密信息安全，以可见光通信监听技术为代表的可见光信息隐蔽传输具有隐蔽性强、不易检测防护、前置LED灯分布广等特点，将会对信息安全产生巨大威胁.首先阐述了可见光通信监听技术在国内外研究现状、监听技术原理和涉及到的关键技术，通过分析可见光通信监听技术的特点，说明该技术将严重威胁国家信息安全，提出有关部门应增强防范意识、使用可见光监听检测设备等手段进行有效应对
