In view of the safety problem brought by the information transmission mode in the traditional mode, the embodiment of the invention provides a video signing method, a video signing device and a video signing system based on a alliance chain.
The brand new application of the block chain in the communication field can completely change the channel of information transmission, and fundamentally solves the problem of path security of information transmission. Advanced encryption technology is adopted in the data communication processes of block chain checking, sending and the like. This technique ensures not only that the source of the data is correct, but also that the data is not intercepted and tampered with by a person in the middle of the process. The blockchain system reduces the conventional network security risk because it eliminates the need for an intermediary party. The user can obtain video contact with a financial institution by using the block chain, the identity confirmation is completed in a remote video form, meanwhile, the specific file is transmitted by using the block chain and signed in an agreement, and the validity and the falsification prevention of the signature are ensured by using a falsification prevention technology of the block chain.
The terms to which the present invention relates are explained as follows:
blockchain (Blockchain): the block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. It is essentially a decentralized database, and the underlying technology is a series of data blocks associated using cryptography, each data block containing information of a batch of network transactions for verifying the validity of the information (anti-counterfeiting) and generating the next block. As a high energy consumption system, to maintain the authenticity and integrity of the block chain, operations can be performed seven trillion times per second, thus requiring a large amount of hardware and energy for support.
Through a distributed protocol, a communication network of a block chain technology can realize communication establishment in less than ten seconds, the communication protocol is developed by using a fragmentation technology, the loading time is optimized, and the block chain technology has a plurality of obvious advantages in the aspects of communication network dispersibility, safety and the like, such as:
1. blockchain technology communication is not blocked by firewalls because each user and each conversation is a distinctive Session (Session) with unlimited access to anywhere in the world, which is useful for enabling secure communications.
2. The block chain technology has user-controlled record storage and has the characteristic of being not tampered, so that the protocol cannot be modified in the signing process.
3. Blockchain techniques may enable advanced encryption for each session, message, and file.
The present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a video subscription method based on a federation chain in an embodiment of the present invention. As shown in fig. 1, the video subscription method based on the alliance chain is applied to an alliance chain network, and includes:
s101: and receiving video data from a video initiating terminal of the alliance chain network, and determining missing data according to a time stamp in the video data.
In step S101, the live cameras of the users (the video initiator, the video receiver, and the third-party video client) correspond to their respective IP addresses. In the video signing process, a multi-purpose camera of a certain user acquires videos of the user in real time, and video data acquired by cameras with different IP addresses are uploaded to a alliance chain.
The uploaded video data comprises at least two parts: one part is the IP address of each camera, the other part is the created time stamp, and finally the hash function value of the IP address of all the cameras and the time stamp is uploaded, namely the hash (the IP1 of the camera, the IP2, … … of the camera, the IP N of the camera and the time stamp). It should be noted that the hash value can be placed in an access-restricted area in the contract layer, so that data can be acquired with restrictions, and the IP address and the timestamp of each road camera can be effectively protected from being tampered.
Each camera IP address of the same user can create a video block chain belonging to itself, for example, "camera IP X" represents a video block chain created by a camera with IP X, and points to the same video block chain node (iniBlock). The head blocks on the block chain corresponding to each camera IP have similar structures, namely a pointer pointing to iniBlock, a camera IP and a timestamp, and subsequent video data acquired by the camera can be hung on the corresponding video block chain according to the head blocks. The video data contains the IP address of the camera, a timestamp, a frame data length, and frame data. For example, camera IP X creates a chain of video tiles as (camera IP X header tile, video tile 1, video tile 2 … … video tile N-1, video tile N).
After the video data module acquires the video data transmitted by the N paths of cameras, the security of the video data of each path is detected and analyzed, and the phenomenon that the video data are completely lost or key frames are disordered due to network problems, malicious tampering and the like is avoided.
After the video subscription is started, video streams are continuously pushed to the alliance chain, video data detected through safety are placed in a local video frame pool by a video receiving end node and are arranged according to the sequence of timestamps, whether video data are lost or not can be detected in time, the situation that videos cannot be recovered at the later stage is prevented, and especially key frames are lost. Since there may be a delay in the P2P network, it may happen that video data of a later time arrives first at the node, and the video data may be temporarily put into the video frame orphan pool. The video data module will determine the missing data according to the time stamp in the video data: if the missing video data is not received for a long time, the video data module determines that the video data is missing data.
Before executing S101, the method further includes:
(1) and (4) proposing a response: and the signing service initiating end node initiates a video signing proposal, and each node of the block chain carries out feedback. Each node comprises each related party in the video subscription service. Corresponding to the invention, the user or the service personnel as a proposing party of video subscription inputs required information on a user interface and initiates the video subscription operation.
(2) And (3) constructing a federation chain: at least two users (a video initiator and a video receiver) involved in the video subscription service are determined to construct a alliance chain.
All the related parties involved in the subscription in the block chain are submitted for proposal application, and after all the responses of the related parties are collected, a federation chain is constructed for all the parties. It should be noted that the alliance chain is only constructed for the feedback users, all information is transmitted, loaded and stored based on the chain in the subsequent signing process, and other nodes which do not participate in the subsequent signing process cannot acquire the relevant information of the video signing service.
The alliance chain can configure an independent channel for each user, and particularly, the invention supports the configuration of an independent channel for multi-purpose camera equipment used by the user, thereby realizing the backup of a multi-video source and avoiding the situations of video data loss, tampering and the like. For example, each user information (including user identification) and a camera IP are used as a set of information sets, a new channel profile is generated for each set of information sets, then a channel for only the camera to which each user belongs to communicate is created according to the channel profile, and each user performs video data interaction through the channel, thereby forming a new alliance chain for each user. And data is sent and loaded through encryption and decryption, so that the interaction safety is guaranteed.
Each user on the blockchain acquires video image data through a camera deployed in the on-site environment and uploads the video image data into the alliance chain. For example, the video initiator and the video receiver are different nodes in a federation chain, and together they form a P2P remote video subscription network. The video data source is acquired 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 the adjacent IP address according to the receiving end IP address corresponding to the missing data.
In specific implementation, after video frame data independently transmitted by IP of each camera is received, firstly, the security of the video data is checked, damaged data or malicious and illegal data are prevented from entering a block chain network, the checked video data are put into a video frame pool, and meanwhile, a plurality of video frames are extracted from the video frame pool according to the sequence of video generation to construct video blocks and wait to be recorded into a video block chain. The invention adopts a workload proving mechanism to fairly compete for the accounting right, a node (a certain camera IP of a user) which obtains the accounting right has the right to propose a video block constructed by the node to be written into a video block chain, the video block is broadcasted to other nodes (third-party video terminals), and the video block is synchronized to the local video block chains of the node after being verified by the other nodes, thereby realizing the synchronization of the video data of the whole network. When all the video data under a certain IP address is lost, S102 and S103 are executed to synchronize video data resolution from other IP cameras (adjacent IP addresses) of the same user.
If the video key frame under a certain IP address is disordered, the detection of the legality and the integrity of the video data is started.
In one embodiment, the process of detecting the integrity of the video data is as follows:
receiving integrity alarm data from a video initiating end, and positioning damaged data according to an IP address and a timestamp in the integrity alarm data; and repairing the damaged data, and feeding back repair information to the video initiating end and the third-party video end.
In specific implementation, after the video data module analyzes data integrity, a risk prompt is initiated on a alliance chain according to preset conditions and actual conditions, and the alarm module responds to the proposal to record bad frame identification information and send the risk prompt for all cameras under the user name of the chain where the bad frame identification information is located. And the node receiving the alarm information positions the video data in the local video frame pool according to the IP address and the timestamp 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 identifier in the alarm module.
In one embodiment, the process of detecting the validity of the video data is as follows:
and receiving security alarm data from a video initiating end, and deleting video data corresponding to the problem IP address in the security alarm data.
And the video initiating terminal checks the IP address of the initiating terminal corresponding to the video data according to the preset IP address to generate the safety alarm data.
The validity indicates whether the video data is from a legal camera, that is, whether the camera IP in the video data belongs to the camera IP address (preset IP address) set in the intelligent contract is checked, and the video data sent from the problem IP address is discarded.
S103: searching homogeneous data from the video frame pool of the adjacent IP address according to the missing data, and generating complete video data according to the homogeneous 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 to perform video subscription.
When the video subscription is normally performed, the video data uploaded by the video initiator is decrypted and loaded, and then is sent to other nodes on the alliance chain, such as a video receiving end. The video receiving end automatically checks the IP address and the time range of a camera to which the video to be extracted belongs, traverses blocks on a video block chain, finds out a corresponding time period by matching the time stamps of the blocks, extracts video data stored in the blocks in the time period, restores the video data into an original video according to the time sequence, displays the original video on a terminal interface and completes one-time complete video data transmission.
Video data related to the subscription service is written into the alliance chain. If the user nodes on the block chain receive the bad frame data or the video data within a period of time, the signing risk is prompted to all the user nodes, and the signing can not be continued until the risk disappears, so that the safety of remote video signing is ensured.
The execution subject of the video subscription method based on the alliance chain shown in fig. 1 may be a video receiving terminal. As can be seen from the process shown in fig. 1, in the video subscription method based on the alliance chain according to the embodiment of the present invention, missing data is determined according to a timestamp in video data, so as to determine an adjacent IP address according to a corresponding receiving end IP address, homogeneous data is searched from a video frame pool of the adjacent IP address according to the missing data, complete video data is generated according to the homogeneous data and the video data, target video data is extracted from the complete video data according to a preset time period, the target video data is ranked according to the timestamp and then displayed for video subscription, so that the requirement of online subscription can be met, and the network security risk can be reduced.
