In view of this, an embodiment of the present application provides a video processing scheme, where after receiving original transaction data and a transaction video sent by a client through a network, a server encrypts the original transaction data by using an encryption token to obtain encrypted transaction data, where the encryption token may be stored in the server or acquired by the server from a cloud, and then embeds the original transaction data and the encrypted transaction data into a corresponding extension field in a video format of the transaction video to generate new transaction video data, where the new transaction video data includes not only an original transaction video but also the original transaction data and the encrypted transaction data, and does not destroy the integrity of the original transaction video.
For a video file, the video file or video stream follows a certain video format, and there is an extension field in the video format, and in practice, the extension field may or may not be filled with content, and does not affect the normal use of the video.
The above technical solution will be described in detail with reference to specific embodiments.
Fig. 1 is a schematic flow diagram of a server-side video processing method according to one embodiment.
As shown in fig. 1, in step 101, a verification request is obtained, and corresponding video data to be verified is determined according to the verification request;
the server side obtains a verification request initiated by the client side, if the verification request carries identification information, corresponding video data to be verified is determined according to the identification information in the verification request, and if the verification request carries the video data, the video data is determined to be the video data to be verified. That is to say, the application provides two application scenarios, one is that the client sends identification information to the server, the server stores the corresponding relationship between each identification information and the video data, the server determines the video data to be verified according to the identification information first, and then verifies whether the video data to be verified is damaged, the other is that the client directly sends the video data to the server, and the server directly verifies the received video data.
The server stores a plurality of video data to be verified, each video data to be verified is provided with identification information, a corresponding relation between each video data and each identification information is formed, each video data can correspond to one or more identification information, but one identification information only corresponds to one video data, that is, one video data can be uniquely determined according to one identification information, so that after the identification information sent by the client is received, the video data to be verified can be correspondingly determined according to the identification information, and a video object required to be verified by the client is determined.
The video data to be verified comprises encrypted transaction data, original transaction data and original video data. The original transaction data can be at least one of transaction amount, transaction content, transaction time and transaction object, and the original video data at least comprises video data for recording transaction process. The specific generation process of the video data to be verified will be described in detail below.
In step 102, extracting original transaction data and encrypted transaction data from video data to be verified;
specifically, according to the method and the device, original transaction data and encrypted transaction data are embedded into original video data at a server side, and new transaction video data, namely video data to be verified, are obtained. Here, extracting the original transaction data and the encrypted transaction data from the video data to be verified specifically includes: searching an extension field corresponding to the video format of the video data to be verified; original transaction data and encrypted transaction data are extracted from the extension field.
In practical application, a video has a corresponding encoding format, for example, for an flv video format, an extended field in the encoding format of the flv video is a script tag, the script tag has a fixed format, and it is good to analyze according to the fixed format, for example, a first field represents a data type, a second field represents a data length, and then a specific data value can be extracted according to the data length.
In step 103, decrypting the encrypted transaction data according to the encrypted token to obtain decrypted transaction data;
the encryption token used for decryption in the application is the same as the encryption token used for encrypting the original video data, so that the decrypted transaction data obtained by decrypting the encrypted transaction data can be compared with the unencrypted original transaction data to confirm whether the video is tampered.
In step 104, it is determined whether the video data to be verified is tampered according to the decrypted transaction data and the original transaction data.
In the step, the decrypted transaction data obtained by decrypting the video is compared with the original transaction data extracted from the video, and the cashing audit video is indicated to be tampered if the comparison result is different.
Determining whether the video data to be verified is tampered according to the decrypted transaction data and the original transaction data, and specifically comprising the following steps: when the decrypted transaction data is the same as the original transaction data, determining that the video data to be verified is not tampered; and when the decrypted transaction data is different from the original transaction data, determining that the video data to be verified is tampered.
The method of generating new transaction video data is described in detail below, as shown in figure 2,

in practical application, original transaction data and original video data generated by a client are sent to a server through a network, the server encrypts the original video data to obtain new transaction video data, and specifically, the original transaction data is encrypted by using an encryption token to obtain encrypted transaction data, wherein the encryption token can be stored in the server or can be acquired from a cloud by the server.
In step 202, the server generates video data to be verified according to the encrypted transaction data, the original transaction data and the original video data.
The video data to be verified is new transaction video data, the server side embeds the encrypted transaction data and the original transaction data into an extension field corresponding to the video format of the original video data to obtain the new transaction video data, and the new transaction video data comprises the original video data and three parts of contents of the original transaction data and the encrypted transaction data.
Taking an flv video format as an example, an extended field in an encoding format of the flv video is a script tag, and the step embeds original transaction data and encrypted transaction data into the script tag of the original video data, so as to generate a new video.
In addition, after the new transaction video data is generated, the server stores the new transaction video data in the server, sets a network video playing address for the new transaction video data correspondingly, and sends the network video playing address to the client, so that the client can access and play the new transaction video data to the server according to the received network video playing address.
Therefore, in the technical scheme, in the video encryption process, the original transaction data are encrypted to obtain encrypted transaction data, the original transaction data and the encrypted transaction data are embedded into the extension field in the original video data, so that the generated new transaction video data comprise two parts of data, one part of the data is the original transaction data, the other part of the data is the encrypted transaction data, the verification of whether the new transaction video data is tampered can be completed by extracting the original transaction data and the encrypted transaction data and decrypting the encrypted transaction data, and thus, the service end provides an effective way for verifying whether the video is tampered.
In a retail scene, the video can be a cash register audit video, the cash register audit video is provided for a bank to be a transaction running line certificate, and transaction counterfeiting is prevented.
