Method for carrying out screen projection by using safety screen projector and safety screen projector

Abstract

The invention provides a method for carrying out screen projection by using a safe screen projector and the safe screen projector, and the method comprises the steps: S1, establishing a connection between the safe screen projector and a screen projection terminal, and receiving first request information sent by the screen projection terminal, the first request information at least comprising the identification information of the screen projection terminal; S2, the safety screen projector detecting whether the identification information exists in a pre-stored terminal white list or not, if yes,executing the step S4, and if not, executing the step S3; S3, the safety screen projector detecting whether a confirmation instruction generated by the key is received or not, if the confirmation instruction is detected, storing the received identification information in a terminal white list, and executing the step S4; and S4, starting a working mode of the safety screen projector. According tothe invention, the authority setting of video playing is carried out by skillfully utilizing the keys on the screen projector, a user needs to confirm the screen projection or screen sharing request sent by the screen projection terminal which is not in the white list of the terminal through the keys on the screen projector, and the screen projection or screen sharing work is carried out after confirmation information is received.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method for projecting a screen using a safe screen projector and the safe screen projector. Background technique [0002] At present, wireless screen projection technology is widely used, and you can enjoy personal pictures, music and videos at any place and at any time. The purpose of the screen projection protocol is to open and facilitate sharing on different audio-visual devices, so there is basically no security for the screen projection content. Control; the methods developed in the prior art to control the content of the projection screen are roughly divided into the following two types: [0003] 1. Encrypted transmission of screen projection content: The digital information on the Internet is transmitted to the screen projection device through encryption. However, although this method increases the security of the transmission process, it greatly reduces t...

Problems solved by technology

[0005] The above method is equivalent to agreeing on a private protocol for security control, which runs counter to the original intention of the screen projection protocol to be open and convenient, and is not easy to implement. It is incompatible with a large number of existing screen projection devices and projection terminals, and has no practical value.
