3. Blockchain techniques may perform advanced encryption for each session, message, and file.
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a flowchart of a video subscription method based on a coalition chain in an embodiment of the invention. As shown in fig. 1, the video signing method based on the coalition chain is applied to a coalition chain network, and comprises the following steps:
s101: video data from a video initiator of the alliance chain network is received, and missing data is determined according to a time stamp in the video data.
When S101 is executed, the live cameras of the respective users (video originating terminal, video receiving terminal, and third party video terminal) correspond to the respective IP addresses. In the video signing process, a plurality of cameras of a certain user acquire videos of the user in real time, and video data acquired by cameras with different IP addresses are uploaded to a alliance chain.
The video data to be uploaded comprises at least two parts: one part is the IP address of each camera, the other part is the created timestamp, and finally all camera IP addresses are sent to the hash function value with the timestamp, namely the hash (camera IP1, camera IP2, … …, camera IP N, timestamp). It is noted that the hash value can be placed in the access restricted area in the contract layer, so that data can be obtained in a limited manner, and each path of camera IP address and timestamp can be effectively protected from being tampered.
Each camera IP address of the same user may create one video blockchain of its own, e.g. "camera IP X" stands for video blockchain created by a camera with IP X and points to the same video blockchain node (iniBlock). The header block on the blockchain corresponding to each camera IP has a similar structure, i.e., a pointer to iniBlock, camera IP, and a timestamp, from which the subsequent video data collected by the camera can be hung on the corresponding video blockchain. The video data contains the IP address of the camera, the time stamp, the frame data length and the frame data. For example, the video blockchain created by camera IP X is (camera IP X header block, video block 1, video block 2 … … video block N-1, video block N).
After the video data module acquires video data transmitted by the N paths of cameras, the safety of the video data of each path is detected and analyzed, so that the situation that the video data are lost or key frames are disordered due to network problems, malicious tampering and the like is avoided.
The video signing is started, then the video stream is continuously pushed into the alliance chain, the video data passing through the security detection is placed in a local video frame pool by a video receiving end node, and the video data are arranged according to the sequence of time stamps, so that whether the video data are lost or not can be timely detected, the later video cannot be recovered, and especially the key frames are lost. Since there may be a delay in the P2P network, it may happen that video data of a subsequent time arrives first at the node, and these video data may be temporarily put into the video frame orphan pool. The video data module determines missing data from the time stamps in the video data: if the missing video data is not received for a long period of time, the video data module determines the video data to be missing data.
Before executing S101, further comprising:
(1) Proposal response: the signing service initiating terminal node initiates video signing proposal, and each node of the blockchain feeds back. Each node includes a respective interested party in the video subscription service. Corresponding to the invention, the user or business personnel is used as a proposer of the video subscription, inputs the required information in the user interface and initiates the video subscription operation.
(2) Constructing a alliance chain: at least two users (video originating and video receiving) involved in the video subscription service are determined to construct a coalition chain.
The related parties involved in the subscription in the blockchain are all filed with proposal, and after all responses of the related parties are collected, a alliance chain is built for each party. It should be noted that the alliance chain is only constructed for the fed-back user, all information is transmitted, loaded and stored based on the chain in the subsequent signing process, and other nodes which do not participate cannot acquire the relevant information of the video subscription service.
The alliance chain can configure an independent channel for each user, and particularly, the invention supports the configuration of the independent channel for the multi-purpose camera equipment used by the user, thereby realizing the backup of multiple video sources and avoiding the conditions of video data loss, tampering and the like. For example, each user information (including user identification) and camera IP are used as a group of information sets, a new channel configuration file is generated for each group of information sets, then a channel for communication only by the camera to which each user belongs is created according to the channel configuration file, and each user interacts with video data through the channel, so that a new alliance chain is formed for each user. The data are transmitted through encryption and are decrypted and loaded, so that interaction safety is guaranteed.
Each user on the blockchain collects video image data through a camera deployed in the field environment and uploads the video image data into the coalition chain. For example, the video initiator and the video receiver are different nodes in a coalition chain, which together form a P2P remote video subscription network. The video data source is obtained by a camera erected in the site environment of each node, and the generated video data is sent to the video initiating terminal and the video receiving terminal.
S102: and determining adjacent IP addresses according to the IP addresses of the receiving ends corresponding to the missing data.
When the video block chain system is implemented, after video frame data independently transmitted by each video camera IP are received, firstly, the safety of the video data is checked to prevent damaged data or malicious illegal data from entering a block chain network, the checked video data can be put into a video frame pool, meanwhile, a plurality of video frames are extracted from the video frame pool according to the sequence of video generation to construct a video block, and the video block is waited to be recorded into the video block chain. The invention adopts a workload proving mechanism to fairly compete for the accounting rights, the node (a certain camera IP of a user) which obtains the accounting rights has the right to propose the video block built by the node to write into the video block chain, the video block is broadcast to other nodes (third party video ends), and the other nodes verify and then synchronize to the local video block chains, thereby realizing the synchronization of the whole network video data. When video data at a certain IP address is lost in its entirety, S102 and S103 are executed to synchronize video data from other IP cameras (adjacent IP addresses) of the same user.
If video key frames under a certain IP address are disordered, the method starts to detect the validity and the integrity of the video data.
In one embodiment, the process of detecting the integrity of video data is as follows:
receiving integrity alarm data from a video initiating terminal, and positioning damaged data according to an IP address and a time stamp in the integrity alarm data; repairing the damaged data, and feeding back repairing information to the video initiating terminal and the third-party video terminal.
In the specific implementation, after the video data module analyzes the data integrity, a risk prompt is initiated to the alliance chain according to the preset condition and the actual condition, the alarm module responds to the proposal to record the bad frame identification information, and the risk prompt is sent to all cameras under the user name of the chain. The node receiving the alarm information locates the video data in the local video frame pool according to the IP address and the time stamp of the camera, restores the video data passing the security detection to the bad frame node, feeds the restoration information back to the alarm module, and deletes the bad frame information identification in the alarm module.
In one embodiment, the process of detecting the validity of video data is as follows:
and receiving the security alarm data from the video initiating terminal, and deleting the video data corresponding to the problem IP address in the security alarm data.
The security alarm data is generated by checking an initiating terminal IP address corresponding to the video data by the video initiating terminal according to a preset IP address.
The validity indicates whether the video data originates from a legal camera, i.e. it is checked whether the camera IP in the video data belongs to the camera IP address (preset IP address) set in the smart contract, and the video data sent on the problem IP address is discarded.
S103: and searching similar data from the video frame pools of adjacent IP addresses according to the missing data, and generating complete video data according to the similar data and the video data.
S104: and extracting target video data from the complete video data according to a preset time period, sequencing the target video data according to the time stamp, and displaying the target video data to sign a video.
When the video subscription normally proceeds, the video data uploaded by the video initiating terminal is sent to other nodes on the alliance chain, such as a video receiving terminal, after decryption and loading processing. The video receiving end automatically checks the IP address and the time range of the video to which the video to be extracted belongs, traverses the blocks on the video block chain, finds the corresponding time period by matching the time stamp of each block, then extracts the video data stored in each block in the time period, recovers the original video according to the time sequence, and displays the original video on the terminal interface to complete one-time complete video data transmission.
Video data associated with the subscription service is written into the coalition chain. If the user nodes on the blockchain receive bad frame data or do not receive video data within a period of time, prompting signing risks to all the user nodes, and continuing signing until the risks disappear, so that the safety of remote video signing is ensured.
The executing body of the video signing method based on the alliance chain shown in fig. 1 may be a video receiving end. As can be seen from the flow shown in fig. 1, the video signing method based on the coalition chain in the embodiment of the invention determines the missing data according to the time stamp in the video data to determine the adjacent IP address according to the corresponding receiving end IP address, searches the same kind of data from the video frame pool of the adjacent IP address according to the missing data, generates the complete video data according to the same kind of data and the video data, extracts the target video data from the complete video data according to the preset time period, sorts the target video data according to the time stamp, and displays the sorted target video data for video signing, thereby solving the requirement of online signing and reducing the network security risk.
