Embodiment 1

[0048] The embodiments of the present application provide a video processing method, such as figure 1 As shown, applied to the encoder side, the method may include the following steps:

[0049] Step S101, obtaining a video source;

[0050] Specifically, a video source is acquired, wherein the video source may be obtained by shooting through a terminal device (such as a mobile phone, a PAD) or a monitoring device (a monitoring camera).

[0051] In step S102, the video source is encoded by the encoder to obtain initial encoding information; for example, if the video source is captured by a mobile phone, the encoder may be the mobile phone. Among them, the encoder (encoder) is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission and storage.

[0052] Step S103, perform a signature operation based on the first private key corresponding to the encoder, the initial encoding information and the ...

Embodiment 2

[0060] like figure 2 As shown, another video processing method is provided, applied to the forwarding node side, including:

[0061] Step S201, determining a second signature value based on the target encoding information, the forwarding node information and the second private key of the forwarding node, storing the second signature value in the blockchain, and the forwarding node information including the forwarding node location information and the forwarding device information;

[0062] Step S202 , adding the second signature value to the extension information that is not involved in decoding in the target encoding information to obtain the target encoding information to be forwarded.

[0063] Wherein, based on the geographic location coordinates of the encoder, device name, device network parameters, and forwarding node location information, forwarding device information, etc., the trajectory and scope of video forwarding can be determined.

[0064] In this embodiment of...

Embodiment 3

[0066] like image 3 As shown, a video processing apparatus is provided, applied to the encoder side, including:

[0067] an acquisition module 301, configured to acquire a video source;

[0068] An encoding module 302, configured to perform encoding processing on the video source through an encoder to obtain initial encoding information;

[0069] A signature module 303, configured to perform a signature operation based on the first private key corresponding to the encoder, the initial encoding information and the encoder information to obtain a first signature value, and store the first signature value in the blockchain;

[0070] The first adding module 304 is configured to add the first signature value to the extended information that is not involved in decoding in the initial encoding information to obtain target encoding information.

[0071] Optionally, the encoder information includes:

[0072] Geolocation coordinates, device name, device network parameters.

[0073]...

Abstract

The invention provides a video processing method and device, electronic equipment and a computer readable storage medium, and is applied to the technical field of block chains. The method comprises the steps: uploading a signature value obtained based on an encoder, a private key corresponding to a forwarding node and video coding information to a block chain node, so that traceability of the video is realized based on the blockchain technology. Besides, the signature value is added to the extended information which does not participate in decoding in the coded information, and thus server resources consumed by transcoding are not increased when the coded information is decoded; in addition, the image quality is not reduced, and extra hardware equipment does not need to be arranged.

Description

technical field [0001] The present application relates to the field of blockchain technology, and in particular, the present application relates to a video processing method, apparatus, electronic device, and computer-readable storage medium. Background technique [0002] At present, there are a huge number of video sources in the Internet and security industry. The speed of video transmission is getting faster and faster with the development of network technology, and illegal videos are also increasing, which seriously threatens the healthy environment of the Internet. It also becomes extremely difficult to trace back such video sources. [0003] At present, the methods of tracing the source of such videos mainly rely on the management information of the streaming media platform and the digital signature of video watermarks in the process of video dissemination. The obtained device information and user information are used to form the original information, the watermark ge...
