Video and audio credible playing method for generating associated abstract based on intra-frame extraction

Abstract

The invention discloses a video and audio credible playing method for generating an associated abstract based on intra-frame extraction, and relates to the technical field of digital security. The method comprises the following steps: in the transcoding service process of the video streaming media, a publishing end extracts data segments with a certain length in each video frame of a video clip atintervals according to a set intra-frame extraction rule to form a data set corresponding to the video frame, and generates a real-time associated abstract corresponding to the video frame by using aone-way hash algorithm; the real-time associated abstract is utilized to obtain a digital signature aggregate; the client receives the video clip embedded with the digital signature assembly, and extracts the digital signature assembly and the original video clip; the digital signature assembly is decrypted to generate a receiving association abstract corresponding to the video frame;and the received associated abstract is compared with the real-time associated abstract, and a player is controlled to play the video clip content according to a comparison result. According to the method, the security policy for ensuring credible playing is transferred to the streaming media receiving end and the streaming media transmitting end from the complex intermediate network, and the engineering overhead of the security policy is reduced.

Description

technical field [0001] The invention relates to the technical field of digital security, and more particularly to a video and audio trusted playback method based on intra-frame extraction to generate an associated summary. Background technique [0002] Video streaming media is currently the largest form of video data dissemination 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 from the source end to the audience end through the Internet often needs to go through a third-party Internet video live broadcast service platform and corresponding video technology service providers. Even if it does not go through a third-party video platform, it needs to be accelerated through a commercial CDN network . In this context, video flows and distributes among these manufacturers, and the network security levels of these manufacturers are uneve...
