A video and audio trusted playback method based on intra-frame extraction to generate association summaries

Abstract

The invention discloses a video and audio trusted playback method based on intra-frame extraction to generate an associated summary, and relates to the field of digital security technology. Extract video clips at regular intervals, and a certain length of data segments in each video frame constitutes a data aggregate corresponding to the video frame, and use a one-way hash algorithm to generate a real-time associated abstract of the corresponding video frame; use the real-time associated abstract to obtain a digital signature aggregate; The client receives the video clip embedded with the digital signature aggregate, extracts the digital signature aggregate and the original video clip; decrypts the digital signature aggregate to generate the received association summary of the corresponding video frame; compares the received association abstract with the real-time association abstract, and controls according to the comparison result The player plays the content of the video segment, and the invention transfers the security strategy for ensuring trusted playback from the complex intermediate network to the two ends of the streaming media transmission and reception, reducing the engineering cost of the security strategy.

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 intra-frame extraction and generation of association summaries. 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 leve...
