Abstract

The embodiment of the invention discloses a method, a device and a system for preventing eavesdropping and stealthy recording in a conference. The method comprises any one or more of the following steps: transmitting N first sound wave signals in an omnibearing manner, wherein for each first sound wave signal, the first sound wave signal is obtained by performing frequency modulation on a specificsignal sequence, and the average amplitude of the specific signal sequence is greater than or equal to a preset threshold, and N is an integer greater than or equal to 1; directionally transmitting asecond sound wave signal to one or more than one audio collector in the X audio collectors of the conference, wherein the frequencies of the first sound wave signal and the second sound wave signal are the same, and are in a frequency band which cannot be perceived by human beings, the second sound wave signal is obtained by performing frequency modulation on the reverse sequence, the reverse sequence is obtained according to N specific signal sequences, and X is an integer greater than or equal to 1. According to the embodiment of the invention, the confidentiality of conference content is improved.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the communication field and video conferencing technology, especially a method, device and system for preventing eavesdropping and stealth recording in a meeting. Background technique [0002] The wide application of video conferencing equipment has brought great convenience to users. At the same time, users have put forward new requirements for the equipment itself according to specific usage scenarios. Among them, the security and confidentiality of conference content is an urgent problem to be solved. At present, the confidentiality of meeting content is usually achieved by manpower, that is, relevant personnel are required to check the security situation of the venue in advance. However, with the development of science and technology, eavesdropping and sneak recording equipment is getting smaller and more hidden, and it is difficult to guarantee the security of manpower. Security...
