503. If the user using the electronic equipment is not the user corresponding to the application account, the privacy information associated with the application account in the target application is continuously hidden in the display interface of the target application.

The processes in steps 501 to 503 may refer to the processes described in the above embodiments, and are not limited herein.

In the embodiment, the detection of the identity recognition is carried out at regular time, so that the influence on the power consumption and equipment loss of electronic equipment such as a mobile phone caused by the long-time opening of the identity recognition function is avoided.

When the user privacy protection system is a blockchain system in the embodiment of the present invention, the electronic device is a node in the blockchain system in the embodiment of the present invention, and the privacy information (for example, personalized recommendation data, historical usage data, and the like) associated with the application account in the target application may be stored in the blockchain. Specifically, in the embodiment of the present invention, the method further includes: when new privacy information associated with the application account is generated in the target application; generating a new block according to the new privacy information; adding the new tile to the chain of tiles. For a specific manner of adding a new block, reference may be made to the description of the block chain system, and details are not described herein.

The following describes a user privacy protection method in an embodiment of the present invention with reference to a specific application scenario.

Referring to fig. 6, a schematic flowchart of another embodiment of a user privacy protection method according to an embodiment of the present invention is shown, where the user privacy protection method is applied to a mobile phone, the mobile phone supports a face recognition function, and a video application a is installed in the mobile phone, and the user privacy protection method includes:

601. it is determined whether video application a is to be enabled.

Video application a function settings open part: after a user starts the video application A, whether the mobile phone supports the face recognition function is detected, and if not, the function that the face recognition can not be started to assist in protecting the privacy video is prompted. If the function of face recognition is supported, the video application A is prompted in a pop-up window mode to protect the privacy video content in an auxiliary mode through the face recognition mode, and a setting button is provided to guide a user to jump to a setting page to start the face recognition auxiliary authentication function. And after the video application A obtains the authorization of the user and starts the face recognition auxiliary authentication, the current application account C and the current user B2 are bound, and the function setting part is completed.

In this embodiment, the implementation is performed on a mobile client side video application a (the device itself is required to support a face recognition function), the front-end logic flow is mainly divided into a face recognition auxiliary protection setting starting flow and a privacy protection actual monitoring flow, the face recognition auxiliary protection setting starting flow is specifically shown in fig. 7, and the detailed description is as follows:

when a video application a (APP in fig. 7) is installed on a mobile phone and is opened for the first time, a mobile phone system API is called in an initialization process to inquire whether a face recognition auxiliary authentication function is supported. If the mobile phone does not support the function, the function cannot be used, and the existing function of the video application A is maintained unchanged. If the mobile phone supports the function, entering a setting process.

Firstly, a dialog box with a clickable button is created, the content of the dialog box is a prompt document, and a user can jump to a setting interface for face recognition assisted identity verification after clicking. And if the user selects the return key, exiting the dialog box and maintaining the original function of the video application A. If the user clicks the setting button, the user jumps to a real setting page, the page is divided into a guiding part and a switch for acquiring the system authority, the guiding part introduces the protection function played by the function to the user in a gallery mode of transverse sliding through the ViewPager, and simultaneously shows the recognition opportunity of face auxiliary recognition, namely the detection opportunities of several kinds of face recognition described in the above embodiment, for example, the opportunities of starting the video application a or jumping from other applications to the video application a and the like.

When a user clicks a button of the starting function to apply for the calling right of the face recognition of the system, the system setting page is pulled up through the system calling, and the video application A is allowed to use the face auxiliary recognition function in the page, so that the setting process is completed.

The following describes in detail guiding face recognition assisted identity verification in the embodiment of the present invention with reference to a specific usage scenario.

Taking a mobile phone system as an Android system as an example, the guidance setting part is divided into a frame popping part for starting the video application A and a guidance part after frame popping is carried out, and after the video application A is started, a system interface is called in a page declaration period onCreate to detect whether the mobile phone supports face recognition. And initializing guided missile framework guiding dialogs after the judgment that the face recognition is supported. And adding a 'to open' button in the dialog box to set the click behavior of the click event detection button, and canceling the current pop-up box after the user clicks the button. And pulls the real guide activity through Intent.

The guiding activity is divided into an upper part and a lower part, the upper part is a gallery realized by using the ViewPager, the opportunity of face recognition of the video application A is displayed through transverse rolling, and the opportunity comprises that when the video application A is started, the video application A jumps from other APPs or when a preset detection interval period arrives. The lower half part is a fixed clickable button which displays the next page in the display process of the gallery until the gallery displays the last page of content, and the button file is changed into 'confirm on'. And opening the system to set a bullet frame when clicking, and applying for the authority of face recognition to the user in the bullet frame. And after the user authorizes the face recognition authority of the video application A, exiting the guide page, returning to the home page of the video application A, and finishing the face recognition auxiliary identity verification setting process.

Privacy video protection function: after the face recognition auxiliary function is started, the user identity is recognized at regular time during the period that the user uses the video application A, and because the long-time start of the face recognition function can influence the power consumption and equipment loss of terminals such as a mobile phone, the face recognition mode is selected to be detected at regular time and fixed point. The recognition occasions are as follows:

(1) and the mobile phone changes from a screen-saving state to a screen-lightening state every time the mobile phone enters the video application A or every time the mobile phone changes from a screen-lightening state.

(2) When the video application a is not opened, the video application a is jumped to from the desktop or other application at a time.

In addition, during the use period of the video application A, the face recognition verification can be performed every 10 minutes, it can be understood that other interval duration settings can be supported, and the detection duration can be set according to the user's own intention.

When the setting of starting the face recognition auxiliary verification is finished, the opportunity is explained to the user through another guide page, so that the user can trigger the face recognition when the mobile phone is turned on next time in the modes of manually turning off the mobile phone screen and the like. Or the video application A is self-grasped to identify the interval time at regular time, and the proper detection interval duration is selected under the condition of comprehensively considering factors such as the power consumption of the mobile phone.

602. When it is determined that the video application a is to be enabled, a face image R1 corresponding to the user B1 who is currently using the cell phone is captured.

Specifically, the front camera of the mobile phone may be used to collect the face image R1 corresponding to the user B1 who currently uses the mobile phone.

603. And acquiring a preset human face image R2 in the mobile phone.

Since the mobile phone in this embodiment supports the face recognition function, the face image R2 of the user B2 corresponding to the application account C may be pre-entered. The step can directly acquire the face image R2 preset in the mobile phone.

604. It is determined whether the face image R1 and the face image R2 match.

If so, go to step 605, and if not, go to step 606.

605. And determining that the user B1 is the user B2 corresponding to the application account C of the video application A, and displaying the privacy information associated with the application account C in the video application A on a display interface of the video application A.

606. And determining that the user B1 is not the user B2 corresponding to the application account of the video application A, and hiding the privacy information associated with the application account C in the video application A in a display interface of the video application A.

Fig. 8 is a schematic diagram illustrating a specific scenario flow for applying privacy protection in the embodiment of the present invention.

After the user starts face recognition auxiliary verification on the mobile phone, the user performs face auxiliary recognition through the background service of the video application A according to polling at a preset time (for example, 10min), and when the user who uses the device currently is recognized to be the same user as the user who logs in and binds with the application account, the current video application A is considered to be in a normal state, and at the moment, the display content of the video application A does not need to be processed. And continuing to poll for the next identification verification. When the identity of the current video application A user is identified not to be the user bound by the login account, the video application A background service sends a message to the main thread to inform all modules of the video application A of the current privacy disclosure state, and the state of the video application A needs to be reset. The main thread of the video application a notifies the current privacy disclosure state of each component of the video application a in an EventBus manner, and corresponding privacy hiding processing needs to be performed, and a viewing history component and a personality recommendation component are taken as examples for description here.

After receiving the notification message of the main thread of the video application a, the viewing history component temporarily stores the real data structure stored in the memory, including the video vid viewed by the user, the viewing time, the viewing duration, and the like, and refreshes the component on the display interface of the video application a by using the empty data structure, at this time, the viewing history displayed on the display interface is refreshed to be in an empty state. But the real account data is still stored in the memory, and the video application A refreshes the interface to display the real data again when the real account owner uses the mobile phone.

Similarly, after receiving the notification message of the main thread of the video application a, the personality recommendation component removes the personality recommendation data in the memory, and retains the data (i.e., the general recommendation data) from which the personality recommendation is removed, so that a third party cannot deduce the personal preference of the real account number user from the personality recommendation data.

When the next face detection opportunity is triggered, if the human application account of the currently used mobile phone is detected, sending a normal global message to the main thread through the video application A background service. The component that receives the message resets the data of the video application a to the normal state.

The following description is given with reference to a process of implementing face recognition detection on a video application a background by using a specific use scene, specifically as follows:

the background monitoring part of the video application A is mainly combined by a monitoring service running in the background and a timer realized by a Handler mechanism to complete polling monitoring, and a global message is sent through EventBus. And a timing mechanism is realized by sending the delay message according to a time interval set by a user in a way that a Handler sends the delay message. When the timing is reached, the Handler executes a preset check logic, and identifies whether the current user is the person bound by the logged account through a face recognition interface of the mobile phone. If the detection is the self, no processing is carried out, and the next detection is continuously waited. If the account is not the user bound by the current account, the account is not used by the user at present, and privacy protection processing is needed.

The Handler is a set of mechanisms provided by android for updating the UI, and is also a message processing mechanism. The main roles of the Handler are two: (1) sending a message in the newly started thread; (2) and acquiring and processing the message in the main thread.

EventBus is an event publish-subscribe bus for Android, developed by GreenRobot. The method simplifies the complexity of communication among all components in the application program, particularly the problem of communication among fragments, and can avoid inconvenience caused by using broadcast communication.

And the video application A background monitoring service sends a message to the main thread, and marks the current state of the video application A as a privacy disclosure state. The main thread receives the message. And sending a notification message to a component registered in the EventBus, wherein the main component for receiving the notification message is a component with privacy disclosure risk, such as a viewing history component, a personality recommendation component, a My like component, a personal collection component and the like. The viewing history component and the personality recommendation component are only taken as examples here.

The viewing history component body is a RecycleView list, and each item of the list is detailed information of a viewed video, a thumbnail and the like. After receiving the notification that the global state is changed into the privacy disclosure state, the data source of the list is replaced by the empty list and the page is refreshed, so that the real data of the list can be hidden, and the blank page is displayed to realize the effect of privacy protection. After receiving the notification that the global state is changed to the normal state, the data of the previous list stored in the memory is taken out to refresh the list again, so that the viewing history data of the video application a can be normally displayed, and fig. 9 is a schematic view of a viewing history interface of the video application a.

The data of the personalized recommendation component is a component for recommending new videos which may be liked by the user according to historical videos clicked, played and the like by the user, and the videos in the component comprise normal operation videos and personalized recommendation videos. And marks which type of video the video belongs to by a flag bit. After receiving the notification that the global state is changed into the privacy disclosure state, screening the data of the personalized recommendation component, assembling a new data list by using a normal operation video to refresh the component, and only storing the data of the personalized recommendation component in a memory to achieve the purpose of privacy protection. And when the component receives the notification that the global state is changed into normal, the complete data stored in the memory is taken out to refresh the component so as to restore the original personalized recommendation data of the video application A.

Specifically, as shown in fig. 10, a schematic diagram of a monitoring flow of a video application a client background service is shown, where monitor service is a service that runs in the video application a background to execute tasks at regular time. The service performs continuous polling monitoring according to the timing monitoring duration set by the user. And calling a system call every time the monitoring is initiated, and judging whether the person currently using the mobile phone is the account number according to the recognition result of the face recognition module of the mobile phone. And sends the results to the various components of video application a via EventBus.

The EventBus is a framework used by the Android end for inter-component communication. By registering the viewing history component, the personality recommendation component, and the like in the EventBus in advance, a message sent by the EventBus can be received. The message sent herein refers to a privacy state change event PrivacyStatusChangeEvent. The viewing history component, the personality recommendation component and the like which receive the message ensure data security in a privacy leakage state by refreshing the current interface by using null data. And the original interface can be redisplayed through real data under the condition that the privacy state is normal.

In addition, a client implementation process of the video application a in this embodiment is described with reference to fig. 11, and as shown in fig. 10, a User Interface (UI) is opened for protecting the client privacy video of the video application a. The screen display device comprises "-1 screen guide content", "home screen guide content" and "+ 1 screen guide content", each screen comprises a page switching area (ViewPager area), and a jump button is arranged in a display interface.

Viewpager, a view flipping tool, provides the effect of multi-page switching. Is a UI control introduced after Android 3.0 and is positioned in a v4 package. The viewport is used by filling it with multiple views by creating an adapter, and switching between different views when sliding left and right.

Wherein, the ViewPager uses the adapter mode, binds the different guide page fragments with the data through the adapter Fragment Pager adapter, and submits to the ViewPager for display. Fragment is used to handle the display and logical work of a lead page, and a single lead page can be considered a Fragment. Taking three guide pages as an example, the content of the guide pages is the timing and interval of face recognition, and the number of the guide pages is dynamically determined by the amount of the guide data, and can be configured by the background issuing. And the Fragment corresponding to the index of the current page needs to be returned in the adapter. And initializing the current page in the corresponding life cycle of the Fragment, and the like.

The skip button is a control button linked with the ViewPager, the OnClickListener of the skip button triggers the sliding operation of the ViewPager, and the current screen of the ViewPager slides to the content of +1 screen. After the content sliding of all the ViewPager is finished, the next jumping action of the jumping button pulls up the system face recognition authorization page. The face recognition function is turned on after the user is finally authorized.

Nowadays, various applications integrate various personalized recommendation and accurate recommendation functions, and the functions can serve users more comfortably and cause the leakage of user privacy. By the face recognition auxiliary verification method provided by the embodiment of the invention, the security of privacy can be kept even when a user is far away from a mobile phone, and related content containing privacy in an application can be refreshed in real time when a non-application account is used by the user, so that the privacy is not leaked. When the application account is used by the user, the application with complete functions of personal recommendation, history watching and the like can be restored, and even if the mobile phone is far away or stolen, the safety of the account does not need to be worried.

In addition, in the embodiment, from the power consumption of the mobile phone, the triggering time is preset to perform auxiliary recognition verification on the human face, and under the condition that the power consumption is not needed to be worried about, more recognition times can be added, and the recognition interval is shortened, so that the recognition instantaneity is improved.

It should be noted that the face recognition auxiliary verification method adopted in the embodiment of the present invention is only one of various recognition methods of the current mobile phone, and based on other recognition methods such as screen fingerprint recognition, post-fingerprint recognition, and the like, the effect similar to the face auxiliary recognition can be achieved, the user can be recognized only by manual verification, and although background silence cannot be achieved like face recognition without disturbing the user operation, the effect of auxiliary recognition can also be achieved, which is also a scheme included in the idea of the present invention.

In order to better implement the user privacy protection method provided by the embodiment of the present invention, an embodiment of the present invention further provides a device based on the user privacy protection method. The terms are the same as those in the above-mentioned user privacy protection method, and details of implementation may refer to the description in the method embodiment.
