Embodiment Construction

[0031] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] as attached figure 1 As shown, a kind of anti-leakage method of electronic whiteboard provided by the present invention, said method comprises the following steps:

[0033] S1. The mobile terminal is located within the sensing range of the whiteboard, and the whiteboard establishes a link with the mobile terminal;

[0034] S2. After the whiteboard detects that it establishes a link with the mobile terminal, it saves the content displayed on the whiteboard to the mobile terminal through NFC;

[0035] S3. When the mobile terminal leaves the sensing range of the whiteboard, the whitebo...

Abstract

The invention provides an electronic whiteboard anti-disclosure method, a whiteboard and a mobile terminal. The method comprises the steps: uploading contents displayed on the whiteboard to the mobileterminal when a conference is interrupted, and trying to remove the contents displayed on the whiteboard; when the mobile terminal is located in the induction range of the white board again, automatically establishing a link with the mobile terminal by the white board, and obtaining the displayed content which is tried out on the mobile terminal. The functions of automatic trial division, storage, recovery and the like of the content displayed on the electronic whiteboard are achieved. The requirement for secrecy is met objectively.

Description

technical field [0001] The invention belongs to the technical field of electronic whiteboards, and in particular relates to a method for preventing leakage of electronic whiteboards, a whiteboard and a mobile terminal. Background technique [0002] Existing electronic whiteboards cannot automatically encrypt the content on the whiteboard, and need to manually clear the content on the whiteboard. If you continue to use it after interruption during use, the deleted data cannot be recovered, which is inconvenient to use. For example, in a company's routine meeting, a ten-minute break is required during the meeting. The question before the speaker is whether to erase the content displayed on the whiteboard; Altered or wiped off by someone, or if someone who is not a participant enters the venue, it may cause leaks in the meeting; if wiped off, it will bring unnecessary trouble to the continuation of the conference work after the break, for example, it is necessary to re-wipe the...
