Abstract

The invention discloses a distributed encryption method for a real-time video. Real-time video stream data are received by using a real-time calculation frame; the real-time video stream data are segmented into video fragment data by using time as reference and each time fragment corresponds to one piece of video fragment data; according to the video fragment data, an elastic distributed data set is constructed, wherein each element in the elastic distributed data set expresses one piece of video fragment data; all elements in the elastic distributed data set are distributed to all node work stations; and the node work stations carry out encryption processing on the video fragment data and output encryption results. According to the method, distributed encryption on the real-time video can be realized rapidly. Compared with the prior art, the method has advantages of simple process, low operation realization difficulty, and good encryption effect.

Description

technical field [0001] The invention relates to the field of media, in particular to a distributed encryption method for real-time video. Background technique [0002] In computer data processing applications, video encryption is a relatively common data processing application. Due to the large amount of video data, usually video encryption operations need to consume a large amount of computing resources. [0003] With the continuous development of distributed system technology, more and more technical fields use distributed data processing technology to reduce the data processing pressure of a single processing system. Distributed data processing technology has also been applied to the field of video encryption. [0004] In the prior art, a native parallel computing framework (map-reduce MapReduce) is usually used to perform distributed encryption on video. Use MapReduce for video encryption. Inside the MapReduce task, in order to prevent the failure of the Reduce task, ...
