The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.
Fig. 1 schematically shows a flow chart of a video transmission control method in an exemplary embodiment of the present disclosure. Referring to fig. 1, the video transmission control method 100 may include:
step S102, receiving a first physiological characteristic parameter of a user acquired by first equipment, and establishing a user account for the user on a block chain network according to the first physiological characteristic parameter;
step S104, responding to a video acquisition request from the user account, and verifying whether the video acquisition request comprises decryption information of a target video;
step S106, circularly acquiring a second physiological characteristic parameter of the user through the first equipment when the video acquisition request comprises decryption information of a target video;
step S108, when the difference value between the second physiological characteristic parameter and the first physiological characteristic parameter is smaller than or equal to a preset value, transmitting the target video to the user account so that the first device can acquire and play the target video.
According to the embodiment of the disclosure, the video file is encrypted and then stored on the block chain network, the decryption information is verified in the video file acquisition process, and the transmission object is verified in real time in the video file transmission process, so that the video file can be effectively prevented from being stolen in the storage process and stolen and recorded in the transmission process, and the security of the video file is improved.
The steps of the method 100 are described in detail below.
In step S102, a first physiological characteristic parameter of a user acquired by a first device is received, and a user account is established for the user on a block chain network according to the first physiological characteristic parameter.
In the embodiment of the disclosure, the server establishes a user account corresponding to the user on the blockchain network according to the retina characteristic parameter of the user, so as to be used for subsequent transmission of the video file. The user account may be, for example, an intelligent contract account, and the intelligent contract account may be used as a node of the blockchain network and is correspondingly recorded in the first device, that is, the user account is bound with the first device, so that the first device transfers a file with the server and the blockchain network through the intelligent contract account. The registration of the user account on the blockchain network can improve the security of the user account, and prevent the video file from being stolen or inverted as much as possible, which is the first key for protecting the security of the video file in the technical scheme of the disclosure.
When a user with a registered user account uses other equipment to obtain a video, the first physiological characteristic parameter obtained by the other equipment can be compared with the first physiological characteristic parameter corresponding to the existing user account, so that the user account corresponding to the user is accurately located, and the user account and the other equipment are bound. In addition, this approach also allows different users to set up different user accounts using the first device, providing conditions for the shared security of the first device.
The first physiological characteristic parameter may include, for example, a retina characteristic parameter, a fingerprint characteristic parameter, a body temperature infrared parameter, an iris characteristic parameter, or other parameters of the user, as long as a unique characteristic of one user can be marked. In the embodiment of the present disclosure, the first device is preferably smart glasses, and the first physiological characteristic parameter is preferably a retina characteristic parameter of the user.
In step S104, in response to the video acquisition request from the user account, it is verified whether the video acquisition request includes decryption information of the target video.
In the embodiment of the disclosure, the user account and the server are both intelligent contract nodes. After each video is uploaded to the server, the video is stored in a plurality of intelligent contract nodes through the server, and an intelligent contract is established. Each intelligent contract is provided with an authorization range, namely the authorization range set when the video is uploaded, the server can encrypt the video by using the public key of the intelligent contract node in the authorization range, and when one intelligent contract node requests to acquire a target video, the server verifies whether the video acquisition request sent by the intelligent contract node has the public key of the intelligent contract node in the authorization range according to the intelligent contract corresponding to the target video, if so, the server transmits the video to the intelligent contract node sending the video acquisition request, otherwise, the server rejects the video acquisition request.
The user account can acquire the video information by updating the node information in the block chain and is displayed to the user through the first device. The first device can respond to an instruction input by a user in various ways to determine a target video which the user wants to acquire, so that a video acquisition request is sent to the server by using a wireless network through a bound user account corresponding to the user.
In the embodiment of the disclosure, whether the user account has the authority to acquire the target video may be determined by verifying whether the video acquisition request includes decryption information of the target video. In this embodiment of the disclosure, the decryption information may include a private key of an authorized intelligent contract node, that is, it may be determined whether the intelligent contract node (i.e., the user account sending the video acquisition request) has the acquisition right of the target video by verifying whether the private key of the intelligent contract node is within the authorized range of the target video.
In addition, the decryption information may also include other information. For example, the decryption information may further include a decryption password of the video, the server may decrypt the target video through the password, and if the decryption is successful and the private key of the user account is within the authorized range, it is determined that the target video may be transmitted to the user account.
The verification of the decryption information is used as a second key for protecting the security of the video file in the technical scheme disclosed by the invention, so that the video file can be further prevented from being stolen.
In step S106, when the video obtaining request includes decryption information of a target video, a second physiological characteristic parameter of the user is obtained by the first device in a loop.
In the embodiment of the disclosure, in order to prevent the video from being illegally recorded, a link of circularly verifying the user characteristics in the video transmission/playing process is provided. When the first device is smart glasses, the video may be projected directly onto the retina of the user. In the playing process, the first device is controlled to circularly obtain the retina characteristic parameters (second physiological characteristic parameters) of the user and upload the retina characteristic parameters (second physiological characteristic parameters) to the server through the user account, so that the server verifies whether the retina characteristic parameters (second physiological characteristic parameters) are consistent with the corresponding retina characteristic parameters (first physiological characteristic parameters) when the user account is registered.
Step S108, when the difference value between the second physiological characteristic parameter and the first physiological characteristic parameter is smaller than or equal to a preset value, transmitting the target video to the user account so that the first device can acquire and play the target video.
If the difference value of the two is within the preset range, the target video is watched by the user by using the intelligent glasses (first equipment), and the target video can be continuously transmitted to the user account; if the difference between the two exceeds the preset range, the video played by the intelligent glasses is possibly stolen and recorded, or the user account is used by other people, and the target video can be stopped from being transmitted at the moment in order to be protected and only played to the target user.
It should be noted that, in the embodiment of the present disclosure, instead of transmitting a complete video file to the first device for the first device to download to the local device for playing, the server provides an online video transmission service for playing, and the first device can only obtain each frame of image in the target video according to the playing speed, or perform a small amount of caching, so as to prevent an illegal user from copying the video file downloaded to the local device to another storage device through the first device.
Through real-time playing and real-time verification, the video can be prevented from being stolen and recorded in the playing process, or the video is prevented from being illegally stolen or used after being downloaded to the local by a user, and the method is a third key for protecting the safety of the video file.
In the embodiment of the disclosure, the smart glasses play the target video by a retina projection method.
Fig. 2 is a functional block diagram of smart glasses in an exemplary embodiment of the present disclosure.
Referring to fig. 2, the smart glasses 2 may mainly include:
a micro projector 21 for receiving and playing a video file;
a prism 22 coupled to the micro-projector 21 for projecting the video file onto the retina of the user;
a retina characteristic collection module 23, configured to collect retina characteristic parameters of a user;
and the controller 24 is coupled to the retinal feature acquisition module 23 and the micro projector 21 and is connected with the server 1 through a wireless network.
The controller 24 receives the video image transmitted by the server 1 through the wireless network, and then plays the video image through the micro projector 21, and the micro projector 21 projects the video image on the prism 22, so that the prism 22 directly projects the video image on the retina of the user. The video image is directly projected on the retina of the user, so that the video can be effectively prevented from being stolen and recorded in the video playing process, and the safety of the video file is improved.
In addition, the controller 24 acquires the retinal feature parameters of the user through the retinal feature acquisition module 23, and sends the retinal feature parameters to the server 1 through the wireless network, so that the server 1 establishes a user account (the attribute of the user account is, for example, an intelligent contract node) for the user on the blockchain network according to a first retinal feature parameter corresponding to the user, and compares a plurality of second retinal feature parameters acquired subsequently with the first retinal feature parameter, and if the difference value between the two retinal feature parameters is within a preset range, the server 1 continuously transmits the video image of the target video to the controller 24; if the difference between the two exceeds the preset range, the server 1 stops transmitting the video image to the controller 24.
In some embodiments, the server 1 may obtain the playing progress of the controller 24 for the video according to the communication with the controller 24, and further send the video image to the controller 24 according to the playing progress, so that the controller 24 can buffer a small amount of video image for the micro projector 21 to play.
Fig. 3 is an interaction diagram of a video transmission control process in an exemplary embodiment of the present disclosure.
The method provided by the embodiment of the disclosure can be applied to a video playing mode of 'person-to-person authorization', for example.
Referring to fig. 3, the server 1 communicates with the smart glasses 2 and the second device 3 through a wireless network. The second device 3 is, for example, an intelligent terminal such as a mobile phone and a tablet computer, and the disclosure does not particularly limit this.
The second device 3 may send a request to the server 1 to register an account on the blockchain network in the form of an intelligent contract node, thereby uploading local video to the server 1 through the account. The video uploaded together with the video may also have authorization information of the video, such as a password (encryption public key), an authorization range, authorization time, and the like, so that the server 1 encrypts the video according to the authorization information and stores the encrypted video on the blockchain network. For example, a function named sendtransmission may be packaged in the mobile application, and the input parameters of the function are information of the packaged encrypted video file, the authorized aging, the authorized account, and the video publishing user. The server stores the function in the Transaction content by using the public key signature authorization information parameter of the authorized person, and then the function is issued to the block chain network, the solidification of the block can adopt a DPOS (trusted Proof of trust) consensus mechanism, the solidified contract has a unique identifier of the contract, and the intelligent contract node in the block chain network can store all contract information to the local after being updated.
The smart glasses 2 register a user account in the form of a smart contract node on the blockchain network, and the smart contract node can acquire the latest data (e.g., video name/cover picture, etc.) in response to the node update information of the blockchain network and store the latest data in the local memory of the smart glasses.
The smart glasses 2 read the local data, and verify the integrity of the local data according to the hash value (signature) of the local data. The local data may include, for example, a video title/cover picture, etc. The intelligent contract network data comprises numerous intelligent contract nodes, each intelligent contract node needs to create an intelligent contract every time when issuing an authorized video, each intelligent contract node can check which contracts the intelligent contract node joins according to a private key of the intelligent contract node, and the video data of the contracts are read according to selection.
After the data integrity is verified, the intelligent glasses 2 (i.e. an intelligent contract node) can respond to a selection request of a user for a target video, send a video acquisition request corresponding to the target video to all intelligent contract nodes according to a private key of the intelligent contract node (actually, due to an election mechanism of a block chain network, a server is often elected as an intelligent contract node for decision making, the video acquisition request is actually sent to a server in charge of decision making), the intelligent contract node receiving the video acquisition request performs authorization verification according to a contract, and after the verification is successful, a file is sent to the intelligent glasses 2. The node for authorization verification is elected in a plurality of intelligent contract nodes by adopting a DPOS (distributed data processing system) consensus mechanism in a block chain network (intelligent contract network), the elected intelligent contract node for authorization verification is a server 1, namely the server 1 verifies a decryption application, and after verification is successful, a video file is sent to the intelligent glasses 2.
Through the process, the point-to-point authorized transmission of the user of the intelligent glasses 2 by the user of the second device can be realized, the video file is effectively prevented from being copied or stolen and recorded in the transmission process, and the communication safety is effectively improved.
In other embodiments of the present disclosure, the authorized range of the video may also be expanded by other methods. For example, the authorized range may be set by the server that receives the video. The server can set the authorization scope to be certain regions (the IP address conforms to the preset rule) and the intelligent contract node can access the video, and can also set the user account (the intelligent contract node) with certain authority to access the video, wherein the authority can be, for example, a VIP user, a paying user, a user who has purchased the video and the like. In addition, the server may also adjust the authorization range of the video in real time according to the latest user payment information and the user account property, which is not limited in this disclosure.
In summary, the embodiment of the present disclosure establishes the user account on the block chain according to the physiological characteristic parameter, verifies the decryption information to determine the authorization range, and controls the continuation and termination of the transmission process of the video file according to the cyclic verification result of the physiological characteristic parameter, so that the security of the video file in the transmission process can be effectively ensured, the video file is prevented from being illegally copied, stolen and recorded, and the transmission security is effectively improved.
