Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of parental lock, and particularly relates to an intelligent parental lock based on display content, a control method and equipment. BACKGROUND

[0002] At present, there are two schemes for the specific implementation of the parental lock, as follows: The first scheme is in the field of digital television. At present, there are various digital signal standards in the world, and the standards used in various countries or regions have certain differences. Different digital signal standards are roughly the same in the implementation mechanism of the parental lock. Taking DVB-T as an example, the application on the television in the scene of watching television programs can obtain parental lock level information by analyzing EIT (Event Information Table) in the code stream. When violent or unsuitable-for-children scenes appear in the process of watching television programs, a dialog box will pop up to prompt the user, and then the display content can be controlled. The premise of this is that content viewing level information, i.e., parental lock information, needs to be added when the television code stream is produced. Obviously, this operation will increase the cost of producing television programs.

[0003] The second scheme is to provide an operation mode setting in the setting interface of a television, a mobile phone, a car machine and the like. Generally, a system mode (preset mode) and a child mode are provided. When a child needs to operate the equipment, a parent can select to enter the "child mode" to give the child the operation of the equipment. In the "child mode", only a small amount of applications, such as wisdom games, Tang poetry and Song lyrics, are available on the equipment, and these applications need to be specially developed by the developer, and the number and theme of these applications are relatively small, and the selectivity is obviously not very friendly.

[0004] The above methods have limited control over the display content. Either the film source needs special processing, or the application needs special customization, or the parent needs to accompany all the time. Obviously, such content control method has certain limitations and cannot achieve "real-time" control. For example, the child may watch online videos, browse web pages or play electronic games for a long time on different devices alone, or watch programs without EIT content on the television, and the parent cannot achieve comprehensive control over the viewing content. SUMMARY

[0005] In view of the above problems, the present application provides an intelligent parental lock based on display content, a control method and equipment, which does not need special processing of the film source, can achieve real-time control of the parental lock on the child's application of the electronic equipment and comprehensive control of the parental lock on the child's viewing of the application content, saves the development cost, and improves the comprehensiveness of the parental lock function.

[0024] Further, the method further comprises:

[0025] The second content level information is sent to the intelligent service end module and sent to a device processing module through the intelligent client module of the client;

[0043] The embodiments of the present application provide an intelligent parental lock based on display content, referring to Figure 1 ,

[0044] The controller module of the parental lock client establishes a communication connection with the intelligent client module, the screenshot module and the timer module respectively;

[0045] The intelligent client module is a service interface end agent and serves as an interface of the parental lock server;

[0046] The intelligent client module sends the content obtained by the screenshot module to the intelligent server module and receives the content level message fed back by the intelligent server module, and forwards the content level message to the device processing module through the controller module;

[0047] The controller module obtains the first content level information of the parental lock server and forwards it to the device processing module;

[0048] The device processing module receives the first content level information sent by the controller module, and forwards the first content level information to the system of the screen-equipped device.

[0049] The intelligent parental lock and the intelligent parental lock control method of the present application are applied to screen-equipped electronic devices, such as notebook computers, desktop computers, all-in-one machines and smart phones, and the present application does not make specific limitations.

[0050] The intelligent parental lock involved in the present disclosure comprises a parental lock server and a parental lock client, wherein the parental lock server is arranged on a server, and the parental lock client is arranged on a device end. The parental lock client comprises a controller module, an intelligent client module, a screenshot module and a device processing module.

[0051] Specifically, the controller module is a logic control module of the parental lock service on the client side, and is specifically responsible for scheduling the intelligent client module, the screenshot module and forwarding the first content level information obtained from the parental lock server to the device processing module. The intelligent client module and the intelligent server module have a common parental lock service interface, the intelligent client module is a client agent of the service interface, and the intelligent server module is a server-side specific implementation of the service interface. The intelligent client module is responsible for transmitting the content obtained by the screenshot to the intelligent server module, and receiving the content level message fed back from the intelligent server module, and then transmitting the content level information to the device processing module. It should be noted that the content level information obtained by the parental lock client is first content level information, and the content level information generated by the parental lock server is second content level information.

[0052] In some embodiments, the screenshot module provides starting or closing the screenshot service; setting a continuous screenshot interval duration;

[0053] When the screenshot module receives the starting screenshot instruction sent by the controller module, the screenshot module periodically intercepts the screen display content according to the screenshot interval duration, and feeds back the intercepted screen content to the controller module.

[0054] The continuous screenshot interval duration is a duration formed by a time interval obtained by setting a crystal oscillator frequency in the timer module.

[0055] Specifically, the screenshot module mainly provides two types of interface services: one is starting or closing the screenshot service; the other is about setting a continuous screenshot interval duration. When receiving the starting screenshot service instruction from the controller module, the screenshot service in the screenshot module will periodically intercept the screen display content according to the screenshot interval duration, and then return the intercepted screen content to the controller module. The device processing module is responsible for receiving the content level information from the controller module, and transferring the content level information to the system of the screen device for corresponding processing.

[0056] For example, if the currently watched video contains bloody pictures, the device processing module receives the corresponding rating information, and according to the rating information, the current application is directly closed.

[0057] In some embodiments, the parent lock server mainly includes an AI engine module, a database module, a preprocessing module and an intelligent server module.

[0058] The AI engine module of the parent lock server respectively establishes a communication connection with the database module and the intelligent server module.

[0059] The AI engine module determines the preprocessing result obtained by the image preprocessing algorithm, generates second content rating information and feeds back to the intelligent server module.

[0060] Specifically, the preprocessing module receives the screenshot content sent by the intelligent server module, obtains image information through the screenshot content, pre-processes and extracts features from the image information to obtain preprocessing results, and sends the preprocessing results to the AI engine module.

[0061] The preprocessing result includes a feature value extracted from the image information by the preprocessing module.

[0062] The preprocessing module is an image preprocessing module, responsible for information acquisition, preprocessing and feature extraction, receives the screenshot content from the intelligent server module, and sends the preprocessing to the AI engine module for processing; the database module is used by the AI engine module.

[0063] The intelligent server module sends the screenshot content received from the intelligent client module to the preprocessing module for feature extraction.

[0064] The extracted feature value is sent to the AI engine module for intelligent identification, and the identification result is fed back to the intelligent server module.

[0065] Specifically, the AI server module is specifically responsible for sending the screenshot content received from the AI client module to the preprocessing module for feature extraction to obtain a feature value, and then sending the extracted feature value to the AI engine module, the AI engine module intelligently identifies the screenshot content, and the evaluation result is fed back to the AI client module through the AI server module.

[0066] Based on the same inventive concept, another aspect of the embodiments of the present disclosure also provides an intelligent parent lock control method based on display content, comprising:

[0067] An intelligent parent lock service starting instruction is obtained; a parent lock service is initialized by a controller module; a screenshot module of a client is run and screen content is intercepted according to a screenshot interval duration, and the screen content is sent to an intelligent server module through an intelligent client module;

[0068] The screen content received by the intelligent service end module is preprocessed by the preprocessing module, including feature processing of image information in the screen content to obtain feature values;

[0069] The preprocessing result sent by the preprocessing module is received by the AI engine module, and content level evaluation is performed on the feature values therein to generate second content level information.

[0070] Further, the method further comprises:

[0071] The second content level information is sent to the intelligent service end module, and is sent to the device processing module through the intelligent client module of the client;

[0072] The intelligent client module converts the second content level information into first content level information and sends it to the controller module, and the controller module controls the first content level information to be sent to the device processing module.

[0073] Further, the method further comprises:

[0074] According to the second content information level received by the device processing module, the service scene is executed;

[0075] Among them, the first level information is executed to close the current application; the second level information is executed to set the time program, and whether the application running time exceeds the set time is determined to close the application;

[0076] If the application running time does not exceed the set time, the application is monitored by counting;

[0077] If the application running time exceeds the set time, the current application is closed.

[0078] The working process of the intelligent parental lock in the present disclosure will be described in detail below in conjunction with examples.

[0079] Referring to Figure 2 When the child has a demand to run a screen device, the parent starts the parental lock service on the device, at which time the parent's monitoring of the child can be performed by the parental lock. The normal operation of the screen device can choose to watch online live broadcast, network video, browse web pages, play games, etc.

[0080] At the same time, the controller module of the parental lock client initializes and runs the AI client module, the screen capture module, the game timer module and the device processing module, etc. Among them, the screen capture module will intermittently capture the content of the screen, specifically, the screen capture module of the running client is run and the screen content is captured according to the screen capture interval, and the screen content is sent to the intelligent service end module through the intelligent client module; wherein, through the controller module, the intelligent client module is sent to the AI service end module.

[0081] The parent lock service end acquires a large number of pictures by using a "web crawler" technology, and manually processes and labels the pictures and performs image preprocessing. On this basis, the content intelligent detection model is continuously trained to finally achieve an algorithm model with a relatively satisfactory recognition rate.

[0082] When the AI server module on the server receives the screenshot content on the end, the AI server module will be handed over to the preprocessing module for feature processing. Specifically, the AI server module will receive the screenshot content from the AI client module and hand it over to the preprocessing module for feature extraction to obtain feature values. Then the extracted feature values are sent to the AI engine module, which intelligently identifies the screenshot content and feeds back the evaluation results to the AI client module through the AI server module. The features related to inappropriate content for children to watch are extracted from the pictures, such as color, shape, texture, etc.

[0083] The AI engine module on the server receives the feature values output from the preprocessing module and performs the following actions: S1: pass the feature values to an algorithm model, which is a content intelligent detection model output by processing and training a large number of labeled pictures, to evaluate and finally generate second content level information, such as violent movies, smoking scenes, and ordinary games; S2: pass the second content level information to the AI server module and transmit it to the device processing module through the intelligent client module and the control module.

[0084] Among them, the intelligent client module converts the second content level information into first content level information and sends it to the controller module, and the controller module controls the first content level information to be sent to the device processing module. The device processing module of the device end (such as a television) receives the first content level and performs corresponding processing according to the business scenario. For the first level information, the current application program is closed; for the second level information, a time program is set, and whether the application running time exceeds the set time is determined to close the application;

[0085] If the application running time does not exceed the set time, the application is monitored by counting; if the application running time exceeds the set time, the current application program is closed.

[0086] For example, the device processing module receives violent and video that affects the physical and mental development of children as first level information, and directly closes the current application program for this content level information.

[0087] For games, TV series and animation programs, the second level information is determined. According to whether the application running time exceeds the set time, the application is determined to be closed; if the application running time does not exceed the set time, the application is monitored by counting; if the application running time exceeds the set time, the current application program is closed.

[0088] For example, the screenshot module obtains that the screen is in a game state, determines to close the application according to an application running time, and continues to allow the application to run when the application running time is less than a set time. The application is stopped when the application running time is equal to the set time.

[0089] Based on the above technical solutions, the controller module of the parental lock client establishes a communication connection with the intelligent client module, the screenshot module and the timer module respectively; the intelligent client module sends the content obtained by the screenshot module to the intelligent server module and receives the content level message fed back by the intelligent server module, and forwards the content level message to the device processing module through the controller module; the controller module obtains the first content level information of the parental lock server and forwards it to the device processing module; the device processing module receives the first content level information sent by the controller module and forwards the first content level information to the system of the electronic device with a screen. Real-time control of the parental lock on the child's application electronic device and comprehensive control of the child's viewing of application content can be realized, development cost is saved, and the comprehensiveness of the parental lock function is improved.
