Abstract

The invention discloses an unmanned aerial vehicle streaming media encryption and multi-level calibration method; the method comprises the steps: carrying out the disassembly and packaging of video streaming data based on the video streaming data collected by an unmanned aerial vehicle, randomly extracting one sub-video transmission data package, and extracting a part of video data A1, audio data A2 and picture data A3 in the sub-video transmission data package; then correspondingly generating, by the server, a random sequence matrix Wn containing sub-video transmission data packet information, responding to generate random numbers of four levels and four sub-servers corresponding to the four levels, performing encryption on the four sub-servers according to the level arrangement, so that the current sub-server is removed only by adopting a secret key during decryption, and the next sub-server starts the unlocking state and can continue to decrypt by using the secret key. That is to say, the multi-level encryption and decryption operation is adopted, and the sub-video transmission data packets are in a random sequence, so that the encryption level is further enhanced.

Description

technical field [0001] The invention belongs to the technical field of streaming media information encryption, and in particular relates to an encryption of unmanned aerial vehicle streaming media and a multi-level checking method thereof. Background technique [0002] Streaming media (streaming media) refers to a technology and process that compresses a series of media data, sends the data through the Internet, and instantly transmits video and audio on the Internet for viewing. This technology enables data packets to be sent like flowing water. [0003] Streaming media information transmission refers to the general term for the technology of transmitting media (audio, video, etc.) through the network. There are two main ways to implement streaming: progressive streaming and realtime streaming. [0004] sequential streaming [0005] Sequential streaming is sequential downloading. Users download files while watching online media. In this process, users can only watch the d...
