Background
In the current agricultural product anti-counterfeiting tracing scheme, a video scheme and a label scheme are generally adopted. The video scheme takes video data generated by shooting a target object as anti-counterfeiting evidence.

Next, a video authentication method in an exemplary embodiment of the present application will be described with reference to fig. 2.
In step S210, first video data to be checked and a first time are obtained. The first video may be video data to be verified containing a target object, such as video data containing a current agricultural product. The first time may be a certain time in the shooting time period of the first video data, for example, a shooting start time or an intermediate time of the first video data may be used as the first time, and the present invention is not particularly limited thereto.
According to an example embodiment, the first video may be acquired by a first video capture device, wherein the first video includes a video image of a predetermined area.
In step S220, a first keypoint in the first video data is extracted. According to an example embodiment, the first keypoint may be a designated recognizable object, and the first keypoint may be, for example, a photographed item, and may also be other objects in the photographing scene, such as a light, a movable object, and the like.
In step S230, second video data is acquired in the blockchain according to the first time. And the second video data is credible video data related to the video to be authenticated. According to an example embodiment, the second video data may be generated by performing consistency verification on a plurality of third video data; and storing the second video data to the blockchain. Wherein the third video data is a video object waiting to be verified as real data.

Wherein the third key point may be a designated recognizable object.
According to an example embodiment, the third video may be acquired by a third video capture device. The third video includes a video image of a predetermined area, for example, a plurality of third video capturing devices are installed at a plurality of positions in the predetermined area to capture a plurality of third videos.
The second video data can be acquired by deploying a certain number of video acquisition points in the peripheral range of the target object video acquisition area and submitting the video data acquired by the acquisition points to a block chain consensus node, wherein the consensus node comprises a trusted node of a third party. And at the block chain consensus node, extracting key points of the data acquired by each video data acquisition point, comparing based on the key points, if the key points are consistent, achieving consensus, and storing the video data into the block chain after carrying out hash operation to form second video data, otherwise, rejecting the data.
In step S240, a second keypoint in the second video data is extracted. According to an example embodiment, the second keypoint may be a designated identifiable object.
In step S250, when the first key point and the second key point are identical, it is determined that the first video is an authenticated video. For example, a first key point extracted from the first video data is a red pillar beside the target object, a second key point extracted from the second video data collected from another shooting point in the shooting area is also a red pillar, and when the first key point and the second key point are found to have a coincident part through comparison, the first key point and the second key point are considered to be in accordance through comparison, and at this time, the first video is determined to be an authenticated video.
According to an example embodiment, the target object in the first video data may also be verified. For example, the following steps can be decomposed: extracting a target object in the first video data; determining label information corresponding to the target object through the first video; and verifying the target object according to the label information. The tag information comprises display information and a timestamp corresponding to the display information; the tag information is stored in the block chain. For example, a tag may be bound to the target object, the tag cannot be opened without inputting a password or a password error, the tag may display random numerical information, or display a random specific color, and the display manner includes displaying a number or other form of code through a display screen of the tag; at the same time, the tag can save the specific number or other form of encoded information that is displayed and upload the encoded information containing the time stamp to the blockchain.

And step S420, obtaining the logo display information through the block chain according to the second time. For example, the encoded information stored in the block chain and including the time stamp may be searched according to the second time to obtain the target display information.
And step S430, extracting display information in the label information corresponding to the target object according to the second time. For example, a corresponding picture at a second time point in the second video may be determined, and corresponding tag information may be extracted in the corresponding picture to extract display information from the tag information.
Step S440, comparing the logo-aligning display information with the display information to verify the target object. By comparison, when the display information of the alignment mark is confirmed to be consistent with the display information content in the first video, the first video data can be verified as the real video recorded with the target object. If the comparison result is inconsistent, the first video data may be fake video data.
