Embodiment 1

[0039] Such as figure 1 with image 3 As shown, this embodiment provides a video and audio trusted playback method based on inter-frame extraction to generate an associated summary, including the following steps:

[0040] S1: During the transcoding service process of video streaming media, the publishing end selects some video frames from all video frames of the video clip according to the set inter-frame extraction rules;

[0041] Usually, the transcoding service of the video publisher is to successively scale, encode and sign the decoded video streaming media;

[0042] There are many kinds of inter-frame extraction rules. This embodiment describes three kinds of inter-frame extraction rules. The first is to select the corresponding video frame according to the value of the Fibonacci sequence, and the second is to select the corresponding video frame according to the square of the odd number and the even number. The combination method selects the corresponding video frame....

Abstract

The invention discloses a video and audio credible playing method for generating an associated abstract based on inter-frame extraction, and relates to the technical field of digital security, and themethod comprises: a publishing end screening out a part of video frames from all video frames of a video clip according to a set extraction rule in a transcoding service process of video streaming media; forming a data set body corresponding to the video frame by the data segments of the screened video frame, and generating a real-time associated abstract corresponding to the selected video frame; generating a digital signature aggregate by using the real-time associated abstract; the client receiving the video clip embedded with the digital signature assembly, and extracting the digital signature assembly and the original video clip; decrypting the digital signature assembly to generate a receiving association abstract corresponding to the video frame. According to the method, the security policy for ensuring credible playing is transferred from a complex intermediate network to the streaming media receiving end and the streaming media transmitting end, and the engineering overhead of the security policy is reduced.

Description

technical field [0001] The present invention relates to the technical field of digital security, and more specifically relates to a video and audio trusted playback method based on inter-frame extraction to generate an associated summary. Background technique [0002] Video streaming media is currently the highest proportion of video data transmission in the Internet. While streaming media provides high real-time network communication services, it has certain security risks. [0003] With the expansion of the Internet scale, the source video often needs to go through the third-party Internet video live broadcast service platform and corresponding video technology service provider through the Internet from the source end to the audience end. Even if it does not pass through the third-party video platform, it needs to be accelerated through a commercial CDN network . In this context, video flows and is distributed among these manufacturers, and the network security levels of ...
