Description
Technical Field
The present application belongs to the technical field of rights management, and in particular, to a content processing method and system for client cooperation.
Background
With the development of internet technology, the mobile internet has come into the lives of people now, and the living habits of people are changed. The access to the internet through a smart phone is popular, people can surf the internet anywhere and anytime, however, the content on the internet is more conveniently browsed.
For example, in a video surveillance system, the content of the surveillance pictures changes in real time. With the change of the screen content, the viewer's request changes. The normal public scene can be completely opened to the ordinary people, but once malignant events such as car accidents, conspiracy, fighting and the like or bloody fishy pictures occur, the minor should be shielded. For another example, some of various online videos, pictures, and contents are not suitable for young people to watch.
In the prior art, generally, a right is set for a user account, a central management system judges the right of a login account and grants a resource which can be used by the user account, and the right control is more suitable for a scene with more stable resource attributes. However, if the attribute of the resource itself is changed in real time, once the attribute of the resource itself exceeds the account authority, a timely response will not be obtained, resulting in that the user with low authority can view the content which is not suitable. Obviously, for the situation that the attribute of the resource itself is changed in real time, a cutting permission control method cannot be applied, and if the camera resource is allocated according to the minimum permission principle by cutting, the resource is seriously wasted.
In addition, after the resource sender receives the resource request of the resource receiver, if the resource sender directly sends the video stream to the resource receiver, huge performance consumption of the resource sender is caused, the exit bandwidth of the resource sender faces severe examination, and a single point of failure is easily formed, so that congestion and rushing of the network are caused.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a content processing method in cooperation with a client is provided, including:
step S1, the resource management server authenticates and verifies the resource receiver account, sets the account permission value of the resource receiver, and issues the account permission value to the resource receiver, and the resource receiver carries the account permission value to initiate a resource request to the resource sender.
The present embodiment takes a video monitoring system as an example, and is also applicable to other content-on-demand systems, such as web browsing and the like. In the video monitoring system, as shown in fig. 2, a resource receiver is a video monitoring client, a resource sender is a front-end device (such as a camera, a network hard disk recorder, etc.) in the video monitoring system, and a resource management server is a video management server, and may also be any background management server in the video monitoring system.
Each resource receiver has a corresponding user account (hereinafter referred to as an account), and the user account is registered in a video monitoring system, for example, registered in a video management server or other management servers, and the account of each resource receiver is authenticated and checked, and the on-demand permission of the account of the resource receiver to the resource transmitter, that is, the permission value of the account of the resource receiver, is set, and the permission value of the account of the resource receiver is issued to the resource receiver. The present application is not limited to which device performs the step, and may be a resource management server or other management server, such as a separately configured user management server. When the on-demand right of the resource receiver account to the resource sender is set, a uniform right value can be set for the resource receiver account, and the on-demand rights of the resource receiver to each different resource sender can also be set to be different, which is not limited in the present application.
It is easy to understand that, in order to prevent the leakage of the account, the encrypted account authority value is issued after the account is verified. After receiving the information, the resource receiver decrypts the information to obtain the information.
And after receiving the account authority value, the resource receiver initiates a resource request to the resource sender with the account authority value.
Step S2, the resource sender identifies the content of the resource to be sent, adjusts the right value corresponding to the resource according to the content of the resource, and carries the right value corresponding to the resource in the sent resource.
In this embodiment, taking the video management system as an example, after obtaining the information of the resource sender, the resource receiver requests the resource sender for a video stream. In the video monitoring system, it is a mature technology that a client requests a front-end device for a video stream, and details are not described here.
In this embodiment, the resource receiver carries its own account permission value when requesting a video stream. A resource sender, taking a video monitoring system as an example, is generally a front-end device of the video monitoring system, such as a network camera, a network hard disk recorder, and the like, and after receiving a resource request of a resource receiver (e.g., a monitoring client), establishes a connection, and sends a video stream to the resource receiver. The front-end equipment of the embodiment intelligently identifies the image content, and adjusts the authority value corresponding to the resource in real time along with the characteristics of the image content.
For example, the front-end device intelligently recognizes image content, and improves the right value corresponding to the resource when finding that a malignant event such as a car accident, a murder, a fighting and the like or a bloody picture exists.
When sending a resource to a resource receiver, a resource sender carries a right value corresponding to the resource.
Step S3, when receiving the resource request sent by the first resource receiver, the resource sender compares the authority value corresponding to the resource with the account authority value of the first resource receiver, and sends the resource request according to the preset policy.
Specifically, the preset strategy in this embodiment is as follows:
if the account authority value of the first resource receiver is smaller than the authority value corresponding to the resource, further judging whether a second resource receiver is receiving the scrambling resource at present, if not, sending the scrambling resource to the first resource receiver, and if so, informing the second resource receiver to forward the scrambling resource to the first resource receiver;
if the account authority value of the first resource receiver is larger than or equal to the authority value corresponding to the resource, further judging whether a second resource receiver receives the unscrambled resource or not at present, if not, sending the unscrambled resource to the first resource receiver, and if so, informing the second resource receiver to forward the unscrambled resource to the first resource receiver;
the resource sender carries the information and account authority value of the first resource receiver when informing the second resource receiver to forward the scrambled resource or the unscrambled resource to the first resource receiver;
and when the second resource receiver forwards the scrambled resource or the unscrambled resource to the first resource receiver, comparing the authority value corresponding to the current resource with the account number authority value of the first resource receiver to determine whether to continue forwarding, and when the forwarding cannot be continued, stopping the forwarding and continuously processing the resource by the resource sender according to the sending strategy.
In this embodiment, the resource sender has the capability of sending two paths of resources, and may send one path of unscrambled resources or send one path of scrambled resources. The resource sender can compare the authority value corresponding to the resource with the account authority value of the resource receiver, and when the account authority value of the resource receiver is smaller than the authority value corresponding to the resource, the scrambled resource should be sent to the resource receiver, otherwise, the unscrambled resource should be sent to the resource receiver, so that the resource receiver with the lower account authority value cannot see the unscrambled resource, the authority control is realized, and some malignant events such as car accidents, conspiracy, fighting and the like or bloody smell pictures are prevented from being seen by underage users.
In order to avoid the performance consumption of the resource sender, the video stream is forwarded by the resource receiver, so that the performance consumption of the resource sender is reduced, meanwhile, the requirement on the outlet bandwidth of the resource sender is reduced, and the risk of network congestion is reduced.
For example, in a video surveillance system, a resource sender is an IPC, and a resource receiver includes a plurality of clients, such as client 1-client 4.
When client 1 requests a video stream from IPC1, IPC1 compares the right value corresponding to the resource with the account right value of client 1, and the following conditions are provided:
in case 1, the account right value of the client 1 is smaller than the right value corresponding to the resource, and at this time, the IPC should send the scrambled video stream to the client 1. At this point, IPC needs to further determine whether there are other clients receiving the scrambled video stream. If no other client is receiving the scrambled video stream, the IPC sends the scrambled video stream to client 1.
If there are other clients already receiving the scrambled video stream, for example, the client 2 is receiving the scrambled video stream, it means that the account right value of the client 2 is also smaller than the right value corresponding to the resource. At this point, the IPC notifies client 2 to forward the scrambled video stream to client 1. The notification message carries the information of the client 1 and the account authority value.
Further, when the client 2 forwards the video stream to the client 1, the right value corresponding to the current resource is compared with the account right value of the client 1 in real time or at regular time, and whether to continue forwarding is determined.
When the client 2 transfers the scrambled video stream, the authority value corresponding to the current resource is compared with the account authority value of the client 1 in real time, and if the account authority value of the client 1 is found to be larger than or equal to the authority value corresponding to the current resource, the forwarding is suspended. At this time, it shows that the right value corresponding to the current resource changes and becomes smaller, and the account right value of the client 1 is larger than that of the client 2, and the client 1 can already receive the unscrambled resource, so the client 2 should suspend forwarding the scrambled video stream, and notify the IPC, and the IPC processes the scrambled video stream again according to the policy.
It is easy to understand that, after the right value corresponding to the current resource changes and increases, if the account right value of the client 1 is smaller than the right value corresponding to the current resource, the IPC may notify the client 2 to continue forwarding.
In case 2, the account right value of the client 1 is greater than or equal to the right value corresponding to the current resource, and at this time, the IPC should send the unscrambled video stream to the client 1. At this point, IPC needs to further determine whether there are other clients receiving unscrambled video streams. If no other clients are receiving the unscrambled video stream, the IPC sends the unscrambled video stream to client 1.
If there are other clients receiving the unscrambled video stream, for example, the client 3 receiving the unscrambled video stream, it indicates that the account right value of the client 2 is also greater than or equal to the right value corresponding to the current resource. At this point, the IPC notifies client 3 to forward the unscrambled video stream to client 1. The notification message carries the information of the client 1 and the account authority value.
Further, when the client 3 forwards the video stream to the client 1, the right value corresponding to the current resource is compared with the account right value of the client 1 in real time or at regular time, and whether to continue forwarding is determined.
When the client 3 forwards the unscrambled video stream, the authority value corresponding to the current resource is compared with the account authority value of the client 1 in real time, and if the account authority value of the client 1 is found to be smaller than the authority value corresponding to the current resource, the forwarding is suspended. At this time, it shows that the right value corresponding to the current resource changes and becomes larger, and the account right value of the client 1 is smaller than that of the client 2, and the client cannot receive the unscrambled resource, so the client 2 should suspend forwarding the unscrambled video stream, and notify the IPC, and the IPC processes the unscrambled video stream again according to the policy.
It is easy to understand that, when the right value corresponding to the current resource changes and becomes smaller, if the account right value of the client 1 is greater than or equal to the right value corresponding to the current resource, the IPC may further notify the client 2 to continue forwarding.
That is, in this application, when the second resource receiver forwards the scrambled resource or the unscrambled resource to the first resource receiver, the method for determining whether to continue forwarding by comparing the authority value corresponding to the current resource with the account authority value of the first resource receiver includes:
when the second resource receiver forwards the unscrambled resource to the first resource receiver, comparing the authority value corresponding to the current resource with the account number authority value of the first resource receiver;
and when the account authority value of the first resource receiver is found to be smaller than the authority value corresponding to the current resource, suspending forwarding.
And when the second resource receiver forwards the scrambled resource or the unscrambled resource to the first resource receiver, comparing the authority value corresponding to the current resource with the account authority value of the first resource receiver to determine whether to continue forwarding, wherein the method comprises the following steps:
when the second resource receiver forwards the scrambled resource to the first resource receiver, comparing the authority value corresponding to the current resource with the account number authority value of the first resource receiver;
and when the account authority value of the first resource receiver is found to be larger than or equal to the authority value corresponding to the current resource, the forwarding is suspended.
It should be noted that, when the forwarding cannot be continued, the forwarding is stopped and the resource sender continues to process according to the sending policy, which is not described herein again. When in use
In another embodiment of the present application, when notifying the second resource receiver to forward the scrambled resource or the unscrambled resource to the first resource receiver, the resource sender further carries information of a third resource receiver having the same authority as the second resource receiver and receiving the scrambled resource or the unscrambled resource, and when the second resource receiver stops receiving the scrambled resource or the unscrambled resource, the information of the first resource receiver and the account authority value are sent to the third resource receiver, and the third resource receiver forwards the information and the account authority value, and notifies the resource sender.
For example, when notifying the client 2 to forward the scrambled video stream or the unscrambled video stream to the client 1, the IPC also carries information of other resource receivers having the same authority as the client 2 and receiving the scrambled video stream or the unscrambled video stream, for example, when the client 3 and the client 2 are receiving the same video stream as the client, the IPC sends the information of the client 3 to the client 2.
When the client 2 stops receiving the scrambled video stream or the unscrambled video stream (for example, the user of the client 2 logs out), the client 2 sends the information and the account authority value of the client 1 to the client 3, and the client 3 forwards the information and the account authority value and informs the resource sender IPC, and the specific forwarding strategy is described above and is not described herein again.
In another embodiment of the present application, when notifying the second resource receiver to forward the scrambled resource or the unscrambled resource to the first resource receiver, the resource sender also carries information of all resource receivers, and when the resource received by the second resource receiver is scrambled or not, selects a fourth resource receiver having the same authority as the second resource receiver and receiving the scrambled resource or the unscrambled resource from the other resource receivers, sends the information of the first resource receiver and the account authority value to the fourth resource receiver, and the fourth resource receiver forwards the information and the account authority value and notifies the resource sender.
For example, IPC also carries information of all other resource receivers, e.g. information of client 3, client 4, when informing client 2 to forward the scrambled video stream or the unscrambled video stream to client 1.
When the resource received by the client 2 is changed in scrambling or not, for example, from scrambled to unscrambled or from unscrambled to scrambled, the client 2 is not suitable for further forwarding. A fourth resource recipient is selected from the other resource recipients that has the same rights as client 2 and is receiving the scrambled resource or unscrambled resource. Assuming that the client 4 has the same authority as the original client 2, the information and account authority value of the client 1 are sent to the client 4, forwarded by the client 4, and notified to the resource sender IPC, and the specific forwarding policy is described above and will not be described herein again.
In the technical scheme of the application, the resource sender intelligently realizes the identification of the picture content and automatically realizes the real-time change of the authority value corresponding to the resource, and carries the authority value corresponding to the current resource in the video stream. After receiving the resource request, comparing the authority value corresponding to the resource with the account authority value of the first resource receiver, sending the resource according to the sending strategy, and forwarding the resource by other resource receivers, thereby reducing the pressure of the resource sender.
In one embodiment, the present application further provides a client-side collaborative content processing system, including a resource management server, a resource sender, and a plurality of resource receivers, wherein:
the resource management server authenticates and verifies the account of the resource receiver, sets the account permission value of the resource receiver, and issues the account permission value to the resource receiver, and the resource receiver carries the account permission value to send a resource request to the resource sender;
a resource sender identifies the content of a resource to be sent, adjusts the authority value corresponding to the resource according to the content of the resource, and carries the authority value corresponding to the resource in the sent resource;
when a resource sender receives a resource request sent by a first resource receiver, comparing a right limit value corresponding to a resource with an account right limit value of the first resource receiver, and sending the resource request according to the following sending strategy:
if the account authority value of the first resource receiver is smaller than the authority value corresponding to the resource, further judging whether a second resource receiver is receiving the scrambling resource at present, if not, sending the scrambling resource to the first resource receiver, and if so, informing the second resource receiver to forward the scrambling resource to the first resource receiver;
if the account authority value of the first resource receiver is larger than or equal to the authority value corresponding to the resource, further judging whether a second resource receiver receives the unscrambled resource or not at present, if not, sending the unscrambled resource to the first resource receiver, and if so, informing the second resource receiver to forward the unscrambled resource to the first resource receiver;
the resource sender carries the information and account authority value of the first resource receiver when informing the second resource receiver to forward the scrambled resource or the unscrambled resource to the first resource receiver;
and when the second resource receiver forwards the scrambled resource or the unscrambled resource to the first resource receiver, comparing the authority value corresponding to the current resource with the account number authority value of the first resource receiver to determine whether to continue forwarding, and when the forwarding cannot be continued, stopping the forwarding and continuously processing the resource by the resource sender according to the sending strategy.
For specific limitations of the content processing system in client cooperation, reference may be made to the above limitations of the content processing method in client cooperation, which are not described herein again.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
