That is, after the user clicks the "key data", the user directly jumps to the time point (i.e., directly jumps to the time point "1: 04") including the content in the media information to play. The content search area may be switched between display and hiding based on the display or hiding function item shown in the number 3, so that the screen display area of the terminal can be effectively utilized.

The above manner of determining the target content based on at least one piece of recommended content can achieve rapid positioning for the target content.

In some embodiments, the terminal may implement the presentation of the target content of the media information in such a manner that: displaying the position information of the corresponding recommended content in the association area of each recommended content in the content searching area; the position information is used for indicating the display position of the recommended content in the media information.

In practical implementation, in addition to the recommended content, the content search area may also display position information indicating a display position of the currently recommended content in the media information, and based on the position information, quick positioning for the target content may be achieved. If the media information is a video, the location information may be a time point at which the recommended content appears in the entire video; if the media information is a document, the location information may be a page number of the recommended content in the document, which is not limited in this embodiment of the present application.

Illustratively, referring to fig. 5, fig. 5 is a schematic diagram of position information of target content provided by an embodiment of the present application, where the position information shown by number 1 in the diagram is a playing time point, and the position information shown by number 2 in the diagram is a page number appearing in a document.

The above-mentioned manner of displaying the position information can further improve the accuracy of the positioning target content.

In some embodiments, the terminal may implement the presentation of the target content of the media information in such a manner that: displaying the content of the media information in a media information display interface, and displaying at least one keyword; in the process of displaying the content, responding to the selection operation aiming at a target keyword in the at least one keyword, jumping to second content from the displayed content, and taking the second content as the target content; and the second content is obtained by searching the content included in the media information based on the target keyword.

In practical implementation, the manner of determining the target content may be determined based on preset keywords, a plurality of keywords for determining the protected content are presented in the media information presentation interface, and the second content is determined in response to a selection operation for the target keywords. There are a variety of display methods for keywords: the media information can be displayed in a suspension manner in a display area of the media information in the display interface, and can also be displayed in a special keyword display area (the content search area mentioned above). In addition, when there are a plurality of second contents determined based on the keyword, since the plurality of second contents have a time-series relationship, the second content appearing earliest may be automatically used as the target content, and the second content list for the user to select may be displayed, and the user may manually operate to select the target content from the plurality of second contents.

Exemplarily, referring to fig. 6, fig. 6 is a schematic diagram of a second content determination interface provided in an embodiment of the present application, in which reference numeral 1 shows keywords for media information, such as "key data", "privacy", "security", "protection", "privacy", and the like, and the keywords are presented in a floating-layer style in the interface.

The mode of determining the target content based on the keywords can be more targeted, and meanwhile, the human-computer interaction experience is improved, namely the participation of the user is stronger.

In some embodiments, the terminal may implement the presentation of the target content of the media information in such a manner that: displaying the content of the media information in a media information display interface, and displaying a content search function item; in the process of displaying the content, responding to a search instruction aiming at the input content and triggered based on the content search function item, skipping the displayed content to third content, and taking the third content as target content; the third content is obtained by searching the content included in the media information based on the input content.

In practical implementation, the content search function item may be suspended in the display area of the media information, or the content search area and the media information display area may be displayed in the media information display interface, and the search function item (including the search box and the corresponding search control) is displayed in the search area. The user can directly determine the target content by inputting the content to be searched in the content search function item (such as a content search box).

Exemplarily, referring to fig. 7, fig. 7 is an interface schematic diagram of a content search function item provided in an embodiment of the present application, where reference numeral 1 shows a content search area in a presentation interface of media information, reference numeral 2 shows a content search area presentation area in the presentation interface of media information, reference numeral 3 shows a content search function item presented in the content presentation area, and reference numeral 4 shows a content search function item directly presented in the presentation area in a floating layer.

In some embodiments, the terminal may implement the presentation of the target content of the media information in such a manner that: displaying a content searching area and a media displaying area in a media information displaying interface, displaying at least one content thumbnail in the content searching area, and displaying the content of media information in the media displaying area; wherein, the content thumbnail is the thumbnail of the content unit of the media information; in the process of displaying the content, responding to the selection operation of the target content thumbnail in the at least one content thumbnail, jumping the displayed content to fourth content corresponding to the target content thumbnail, and taking the fourth content as the target content.

In practical implementation, the terminal may also determine the target content according to the content unit of the media information. The presentation style for the content unit may be presented in the form of a content thumbnail, for example, a thumbnail of the content unit may be displayed in the content search area. In addition, the content units of the media information may be divided according to the type of the media information: when the media information is a conference recording video with the presentation as content, the content unit can be each presentation; when the media information is a scene video, the content unit can be scene content when the scene is shot or a lens in the scene; when the media information is a common document (article), the content unit may be content corresponding to each page. The embodiment of the present application does not limit the specific form of the content unit. Meanwhile, due to the size limitation of the terminal screen, the thumbnail can be provided with a function of enlarged display, namely, after the thumbnail obtains a focus, the thumbnail can be enlarged and displayed in a relevant area, so that a user can conveniently select the target content.

Exemplarily, referring to fig. 8, fig. 8 is a schematic diagram of a thumbnail of a content unit, taking media information as an example, where number 1 in the figure shows a thumbnail for the content unit, where the thumbnail may be a thumbnail corresponding to each frame image containing target content, and after the thumbnail shown in number 2 in the figure obtains a focus, an enlarged image (shown in number 3 in the figure) for the content contained in the thumbnail may be presented, so that the target content in the thumbnail can be more clearly shown; in response to a trigger operation for a target thumbnail in the thumbnail, such as double-clicking the thumbnail shown by the number 2, the content of the presentation of the media information can be directly jumped to the content corresponding to the thumbnail (the content shown by the number 4 in the figure). In practical applications, the position information of the content corresponding to the thumbnail in the media information, such as the thumbnail corresponding to number 2 shown as number 5 in the figure, can also be displayed, and the position appearing in the video is the time point "1: 18". In the figure, numeral 2 indicates a thumbnail image when the content unit is a page number when the media information is an article. Numeral 3 shows that when the cursor is hovered over the thumbnail, an enlarged view corresponding to the content indicated by the thumbnail is presented.

By the method for displaying the content units of the media information through the thumbnails, the user can conveniently preview the content of the corresponding content units, and the target content units are further determined.

In some embodiments, the terminal may implement the presentation of the target content of the media information in such a manner that: when the media information is a video, playing the content of the video in a media information display interface, and displaying a playing progress bar for indicating the playing progress of the video; and in the process of displaying the content, responding to the progress adjustment operation triggered based on the playing progress bar, skipping the displayed content to the fifth content which is indicated to be adjusted by the progress adjustment operation, and taking the fifth content as the target content.

In actual implementation, when the media information is a video, a play progress bar for indicating a play progress may be displayed in the process of playing the video, and a user switches the displayed content by adjusting the play progress bar. Namely, the target content is determined by dragging the playing progress bar.

Illustratively, referring to fig. 9, fig. 9 is a schematic diagram of a play progress bar provided in an embodiment of the present application, in which reference numeral 1 shows the play progress bar for controlling the play progress of media information, and in response to an adjustment operation on the play progress bar, the play progress of the media information may be adjusted. In addition, the target content of the media information can be marked on the playing progress bar, and when the progress bar is dragged to the corresponding time point, a thumbnail of the target content corresponding to the current time point can be displayed, so that a user can select whether to jump to the target content corresponding to the thumbnail.

In step 102, a content encryption command is received, wherein the content encryption command is used for indicating that all or part of the target content is encrypted.

In actual implementation, after the terminal determines the target content based on step 101, a content encryption operation for the target content may be further performed, where the content encryption may be performed for all the content of the target content or for part of the content of the target content. Namely, the terminal executes the encryption operation corresponding to the content encryption instruction on the target content based on the received content encryption instruction.

To describe the triggering manner of the content encryption command, in some embodiments, the terminal may receive the content encryption command by: the terminal displays an automatic encryption control in a media information display interface; and receiving a content encryption instruction in response to a triggering operation for the automatic encryption control.

In practical implementation, the terminal may receive a content encryption instruction based on the automatic encryption control, where the content encryption instruction is to automatically encrypt the target content. When the media information is a video, the starting time point of the target content appearing in the video and the ending time point of the target content appearing in the video are required to be firstly, and the video content (including voice) from the starting time point to the ending time point is automatically encrypted.

For example, referring to fig. 4, in response to the triggering operation of the "encryption" control in the figure, a part of content (i.e., content corresponding to the time point "1: 04" in the figure) in the currently presented media information may be automatically encrypted, so that the part of content may be controlled to be in an invisible state in the subsequent presentation process.

In some embodiments, the terminal may further receive the content encryption instruction by: displaying a smearing encryption control in a media information display interface; and receiving a content encryption instruction in response to the smearing operation triggered based on the smearing encryption control.

In actual implementation, the terminal may further receive a corresponding content encryption instruction through a smearing encryption control presented in the media information presentation interface. In practical application, when a user needs to encrypt part of content in target content, a content encryption instruction for the part of content in the target content can be triggered by triggering the smearing encryption control.

Exemplarily, referring to fig. 10, fig. 10 is a schematic view of smearing encryption provided by an embodiment of the present application, where reference numeral 1 in the figure shows a smearing encryption control, and reference numeral 3 shows target content, where the target content is part of data in a certain page in a presentation. In practical applications, with continued reference to fig. 10, in response to a trigger operation for the "encryption" control in the figure, the media information may be controlled to be in an encryptable state, and an encryption mode selection interface including two functional items, that is, "automatic encryption" and "smearing encryption" is presented, where the process of implementing "automatic encryption" which may also be referred to as "one-key encryption" is the same as that of the "encryption" control in fig. 4.

In some embodiments, the terminal may also receive the smearing operation by: the terminal responds to the triggering operation aiming at the smearing encryption control and displays an icon corresponding to at least one smearing tool; responding to the selection operation of a target icon in at least one icon, and displaying a target smearing tool corresponding to the target icon; receiving the application operation triggered based on the target application tool.

In practical implementation, after the terminal responds to the triggering operation for the smearing encryption control, the terminal can control the target content to be in a spreadable state, and select the target smearing tool to trigger the smearing operation for the target content. In practical applications, the degree of fineness of the smearing on the target content can be controlled by different types of smearing tools. For example, the application tool may be a "pen" for line application, a "brush" for irregular area application, or a "shape brush" for regular area application, and the specific form of the application tool is not limited.

Illustratively, referring to fig. 10, in response to a trigger operation for a "smear encryption" function item shown by the number 1 in the drawing, a smear tool selection interface is presented, and in response to a selection operation for a target smear tool, a smear operation is performed with the target smear tool (a "pen" that performs line smearing) in the presentation area.

In some embodiments, the terminal may also receive the content encryption instruction by: the terminal displays a box selection encryption control in a media information display interface; responding to the trigger operation aiming at the box selection encryption control, and controlling the target content to be in an editing state; in response to a content selection operation for the target content in the editing state, displaying a selection box including the selected content; content encryption instructions for the content included in the box are received.

In actual implementation, the terminal may further perform area selection on the content in the target content through the box selection encryption control to obtain a part of the content in the target content, and receive a content encryption instruction for the content included in the box selection when the operation triggered based on the box selection encryption control for selecting the area is completed.

Exemplarily, referring to fig. 11, fig. 11 is a schematic view of a box encryption provided in an embodiment of the present application, where media information is a video based on a presentation, a target content is a picture in a current presentation page, at this time, a "box encryption" control shown by trigger number 1 is used to present a box (regular quadrangle, which may also be in other shapes) shown by number 2 in a presentation area, determine a starting point of the box, drag the box, enable a part of content in a current frame image in the video to be in an area formed by the dragging of the box, and trigger a corresponding completion operation (a "√" function shown by number 3), at this time, a content encryption instruction for the selected content in the box can be received; when a cancel frame selection operation is triggered (an "x" function item shown by the number 3), an operation related to frame selection encryption can be canceled.

Above-mentioned smear tool based on different grade type is paintd the encryption to target content, can use the encryption demand of various different encryption precisions, improves encrypted universality, can be applicable to the encryption of various target content, can also effectively improve the accuracy nature of encrypting simultaneously.

In step 103, in response to the content encryption instruction, the encrypted content indicated by the floating layer overlay content encryption instruction is adopted.

In actual implementation, the terminal encrypts the target content of the media information through the encryption processing logic in response to the content encryption instruction. The encryption processing logic comprises the following two processes: and encrypting the key page corresponding to the target content in the media information and encrypting the voice information corresponding to the target content in the media information. Firstly, converting a key page corresponding to target content into a frame image sequence, and determining the position where a first frame image in the frame image sequence begins to appear in media information and the position where a last frame image in the frame image sequence finally appears in the media information (wherein, the position of the frame image can be embodied in a time point mode in a playing progress bar). For media information containing teletext content, a key page may occupy a plurality of successive frame images in a sequence of frame images. If the play time of a presentation to be encrypted is 2 minutes based on the media information of the presentation, each frame image corresponding to the 2 minutes of media information is encrypted individually (the same frame image is encrypted in a combined manner), so that the encryption of the presentation to be encrypted can be completed. Secondly, performing an encryption operation on the voice information corresponding to the target content, specifically, performing voice recognition on the voice information corresponding to the target content, performing voice masking on the voice content obtained through recognition, encrypting the point information or short message aiming at the encryption of a single certain information, namely, performing encryption processing on data, namely, performing compression coding processing through a mobile terminal and a communication network, performing regular pulse excitation-long prediction (RPE-LTP) coding through PCM coding and a vocoder at the vocoder, and finally outputting the voice subjected to the compression coding. After the image information and the voice information corresponding to the target content are encrypted, the encrypted content can be covered by the floating layer, that is, the encrypted content can be in an invisible state by adopting a floating layer covering mode, so that the data security is ensured. For example, after the media information is encrypted, when the target content of the media information is shown again, the floating layer of the 'content is encrypted' is directly displayed, or the encrypted watermark of the complete page is provided, and the user is informed that the content is encrypted through the display of characters and graphs.

In some embodiments, the terminal may further receive a content encryption instruction triggered based on the automatic encryption control, and automatically overlay all content of the target content with the floating layer in response to the content encryption instruction.

In practical implementation, when the encryption type for the target content is automatic encryption, the floating layer may be used to cover the entire content of the target content. It should be noted that, when the media information is a video, the time length of the floating layer display is equal to the display time length of the target content in the video, that is, the terminal determines the starting time point of the target content appearing in the video and the ending time point of the target content in the video, determines the display time length of the target content based on the ending time point and the starting time point, and when the target content is displayed, the floating layer starts to be displayed from the starting time point until the floating layer disappears from the ending time point. When the media information is a document comprising a plurality of pages, the floating layer directly covers the page number of the target content.

Exemplarily, referring to fig. 12, fig. 12 is a schematic diagram of a floating layer presentation provided in an embodiment of the present application, where media information is a video as an example, a target content start presentation is "1: 18" shown in a number 2 in a time point diagram, and a time point of ending presentation is "1: 58" which is a second before "1: 57" shown in a number 3, then for a video with completed encryption, in a process of the video presentation, the video is normally presented at "1: 17" shown in a number 1 (i.e. before "1: 18"), starting from "1: 18" shown in a number 2, the floating layer is presented to cover the target content until "1: 58" shown in a number 3 is a second before "1: 57", and then the related content of the video is normally presented again at "1: 58" shown in a number 3.

In some embodiments, the terminal may further receive a content encryption instruction triggered based on the smearing encryption control, and in response to the content encryption instruction, display a smearing track of the smearing operation by using the floating layer, and use the content covered by the smearing track as the encrypted content indicated by the content encryption instruction.

In practical implementation, the smearing encryption may be to erase or hide the target content by a pen touch or other encrypted hiding manner to protect the content. When the encryption type for the target content is the smearing encryption, the floating layer can be used to display a smearing track corresponding to the smearing operation, that is, the shape and size of the floating layer are the same as those of the smearing track. In this case, the floating layer does not cover the entire content of the target content, but only covers a part of the target content subjected to the smearing operation. It should be noted that, when the media information is a video, the floating layer appears for the same time length as the smeared content is displayed.

Illustratively, referring to fig. 10, clicking the number 1 in the figure to show the "smearing encryption" function item, presenting a smearing tool selection interface shown in the number 2, in response to a selection operation (selecting a "pen" in the figure) for a target smearing tool, smearing the image-text information presented in the media information to obtain a smearing track shown in the number 3 in the figure, and directly presenting the smearing track shown in the number 3 when the smeared content is presented, so as to make the smeared content in an invisible state.

In some embodiments, the terminal may further receive a content encryption instruction triggered by the box-based encryption control, and in response to the content encryption instruction, overlay the content included in the box with the floating layer.

In actual implementation, the terminal can select the frame of the target content through the frame selection encryption control aiming at the target content with a large area. In practical application, a box selection tool is presented by triggering a box selection encryption control, then a starting point of a box selection is determined, the content selected by the box selection is used as target content in response to the dragging operation of the box selection, when the dragging operation is completed, a content encryption instruction for the content included by the box selection is received, and at the moment, the content included by the box selection is covered by a floating layer.

Exemplarily, referring to fig. 11, taking a video in which media information is based on a presentation as an example, a target content is a picture in a current presentation page, at this time, a "box encryption" control shown by a trigger number 1 presents a box (regular quadrangle, which may be in other shapes) shown by a number 2 in a presentation area, determines a starting point of the box, drags the box, so that a part of content in a current frame image in the video is in an area formed by the dragging of the box, and triggers a corresponding completion operation (a "√" function shown by a number 3), at this time, a content encryption instruction for the selected content in the box may be received, and the content in the box is covered with a floating layer; when a cancel in-box operation is triggered (an "x" function item shown at number 3), the box encryption related operation may be cancelled.

The content encryption instruction triggered by the box selection encryption control can realize the selection operation of the content with a large area, so that the acquisition efficiency of the target content can be improved, and the encryption operation rate can be further improved.

In some embodiments, the terminal may further locate the encrypted target content by: marking the position of the target content in the media information, and displaying corresponding marking information; and in the process of showing other contents different from the target contents, when a trigger operation aiming at the mark information is received, displaying the encrypted contents indicated by the content encryption instruction covered by the floating layer.

In actual implementation, after the target content in the media information is encrypted, the encrypted target content may be edited again. For example, when the user finds that the encrypted target content is not accurate (e.g., too much or too little), the encrypted target content may be edited again. Therefore, in order to quickly locate the position of the encrypted target content, the position of the encrypted target content in the media information can be marked, and thus, the encrypted target content can be quickly located based on the relevant mark in the process of showing other content of the media information different from the target content. Wherein the other content may be regarded as content included in the media information other than the target content. In addition, different encrypted target contents may be marked by different marking patterns.

Exemplarily, referring to fig. 13, fig. 13 is a schematic diagram of position marks of target content provided by an embodiment of the present application, taking media information as a video as an example, in the figure, in a playing progress bar of the video, positioning information a1-a2 and b1-b2 of 2 encrypted target contents in the video are shown in different display styles, that is, in the process of playing the video, when playing time point a1, a floating layer is presented to cover corresponding content until time point a2, so as to prompt a1-a2 that the corresponding target content is encrypted, and after playing time point a2, the media information is normally played until playing time point b1 presents the floating layer again to cover corresponding content until time point b2, and then the media information is normally played. At this time, the user finds that the target content at the position a1-a2 is more than the content actually required to be encrypted, and needs to edit the encrypted content at the position a1-a2 again, and at this time, the user only needs to click the mark of a1-a2 or directly adjust the playing progress bar of the video to the time point a1, so that the target content at the position a1-a2 can be located.

The mode for marking the encrypted target content is convenient for a user to quickly locate the position, so that operations such as modification of the encrypted content can be performed, the marked content can be quickly located, and secondary operations for the encrypted content can be improved.

In some embodiments, after the content indicated by the floating-layer overlay content encryption instruction is encrypted, the terminal may also revoke the corresponding encryption operation by: and in response to the revocation operation aiming at the content encryption instruction, removing the floating layer covered on the content and displaying the content in a visible state.

In practical implementation, after the encryption operation is performed on the target content, the encryption on the target content may also be revoked in response to a revocation operation on the content encryption instruction, that is, the overlay floating layer is removed, so that the target content is in a visible state.

Exemplarily, referring to fig. 14, fig. 14 is a schematic diagram of a revocation operation provided by an example of the present application, in which reference 1 shows a previous revocation control, and clicking "previous revocation" can revoke an encryption operation performed on a target content for one time, and reference 2 shows a next revocation control, and clicking "next revocation" can revoke an encryption operation performed on a target content for the next time; clicking the 'one-click cancel' control shown by the number 3 can cancel the encryption operation executed on the content of the media information in the media information display process.

By providing different types of revocation controls, revocation of different granularities can be performed on encrypted content, and media information can be restored in time.

In step 104, in response to the content generation instruction, the target media information is generated, and when the content in the target media information is displayed, the content is controlled to be in an invisible state.

In actual implementation, after the encryption operation on the target content of the media information is completed, the target media information including the encrypted content may be generated, and the generated target media information may be stored for other users to perform related operations. When the target media information is presented again, the encrypted target content is in an invisible state. Thus, the security of the media information can be effectively improved.

In some embodiments, when the media information is a video, the target content is a frame image of the video, and the content encryption instruction indicates that the encrypted content is the target image content included in the frame image. The terminal may control the content to be in the invisible state by: in the process of playing the video, when a target video clip in the video is played and the target video clip comprises a plurality of frame images containing target image content, the target image content in each frame image is controlled to be in an invisible state.

In practical implementation, when the media information is a video, the media information is composed of a plurality of frame images with a time sequence relationship, and if the encrypted content indicated by the content encryption instruction received by the terminal is the target image content included in the frame images, the terminal needs to acquire all the frame images corresponding to the current target image content in the video, and in the process of playing the video, control all the frame images including the target image content to be in an invisible state, and shield corresponding voice information (that is, voice related to the target image content is in an inaudible state).

Illustratively, referring to fig. 15, fig. 15 is a schematic diagram of content units provided by an embodiment of the present application, where a video shown in the diagram is a session record, the content units are frame images, an annual summary including 15 presentations is shown in the video, when the 8 th page is presented, that is, the content shown by number 2 in the frame images at the time points of "1: 24" of the entire video is encrypted, since the content shown by number 2 appears on the 8 th page of the entire presentation corresponding to the video, the starting time point and the ending time point of the presentation of the 8 th page in the video are obtained, and it is assumed that the starting time point of the presentation of the 8 th page in the video (the playing time length is 3 minutes and 45 seconds) is "1: 10 "(time point shown in number 3), and the ending time point is" 2:38 "(time point shown in number 4), then the corresponding frame images in the time period from" 1:10 "to" 2:38 "are in an invisible state (i.e. shielded by using a floating layer) during playing, and the voice in the time period from" 1:10 "to" 2:38 "is shielded (i.e. the voice is in an inaudible state).

In some embodiments, when the media information is a video, the terminal may mask an audio segment corresponding to the target video segment by: the terminal acquires audio clips corresponding to a plurality of frame images; encrypting the content of the audio clip to obtain an encrypted target audio clip; in the process of playing the video, when the target audio clip is played, the target audio clip is shielded.

In practical implementation, when the media information is a video, and when a target video segment in the video is controlled to include a plurality of frame images containing target image content and to be in an invisible state, the terminal further needs to encrypt an audio segment (target audio segment) corresponding to the plurality of frame images, and when the target audio segment is played in the process of playing the video, the target audio segment is directly shielded. In practical application, when the terminal plays the target audio clip, the terminal can replace the target audio clip with other audio clips with equal duration, and can also directly control the target audio state to be in a mute state. In addition, the terminal may determine the target audio segment by means of speech recognition, and at the same time, the encryption processing logic (technical implementation process) for the target audio segment may be implemented by the following means: and carrying out compression coding processing on the target audio segment by combining PCM coding and RPE-LTP coding, and outputting the audio segment after compression coding.

Illustratively, a 36-minute-duration video conference M (including 48 presentations) is provided, wherein the 3 rd presentation P is protected content (i.e., requires encryption processing), a frame image sequence Q of the 3 rd presentation in the video M is determined, assuming that 25 frame images are included, an audio clip corresponding to the 25 frame images is determined, the obtained audio clip is compressed and encrypted, and masking processing is performed on the target audio clip.

In some embodiments, referring to fig. 16, fig. 16 is a flowchart of an audio segment masking process provided by an embodiment of the present application, and is described in conjunction with the steps shown in fig. 16.

Step 201, when the media information is a video, the terminal acquires an audio file in the video, and performs semantic recognition on the audio file to obtain a recognized content.

In practical implementation, the terminal performs semantic understanding on an audio file corresponding to a video in a voice recognition mode to obtain voice content corresponding to the video. The terminal can identify pronunciation phonemes in the audio file through a speech recognition model constructed based on a GMM-HMM model, and find Chinese characters (words) or words with corresponding semantics in a dictionary to obtain identified contents.

Based on the encrypted content indicated by the content encryption directive, a search is performed in the identified content to determine an audio clip matching the encrypted content indicated by the content encryption directive, step 202.

In actual implementation, the terminal parses the content encryption command to obtain the encrypted content indicated by the content encryption command, and in the voice content obtained in step 201, retrieves the encrypted content indicated by the content encryption command, and determines the specific position of the audio clip by corresponding to the start time point and the end time point of the audio clip in the video, and takes the audio clip as a matched audio clip.

Step 203, encrypting the content of the audio clip to obtain the encrypted target audio clip.

In actual implementation, the terminal encrypts the obtained audio clip (i.e., performs a masking process on the audio clip). The implementation logic of encryption may be to perform compression coding processing on the target audio segment by combining PCM coding and RPE-LTP coding, and output the target audio segment after compression coding.

Step 204, in the process of playing the video, when the target audio clip is played, the target audio clip is shielded. In practical implementation, when the terminal plays a video, and when the terminal plays a target audio clip, the terminal can replace the target audio clip with another audio clip (for example, playing an advertisement audio, a busy tone, or playing a voice loop in a manner that the voice is shielded, etc.) to implement shielding processing for the target audio clip; the target audio clip can be controlled to be in a mute state, and prompt information that the audio clip is shielded is shown to inform the user that the target audio clip is encrypted. It should be noted that, when the graphics context information in the video corresponding to the target audio clip is the encrypted content, the terminal controls the graphics context information to be in the invisible state while the target audio clip is displayed.

In some embodiments, when the terminal displays the content in the target media information, the terminal displays an encrypted prompt message, where the encrypted prompt message is used to prompt that the content corresponding to the current display position is encrypted.

In actual implementation, when the terminal displays the content in the target media information, when the encrypted target content is displayed, the prompt information for prompting that the content corresponding to the current display position is encrypted can be displayed. The encrypted prompt message may be at least one of text message, image message, or animation message, where the image message or the animation message may be a message with an advertisement announcement function, such as playing an animation related to the content of the media message, and the embodiment of the present application does not limit the specific form of the encrypted prompt message.

Exemplarily, referring to fig. 17, fig. 17 is a schematic diagram of an encrypted hint provided by an embodiment of the present application, where the encrypted hint "the content is encrypted" is a text type encrypted hint shown by number 1 in the figure; the number 2 indicates the animation type information, which may be set by the publisher of the media information, and may be related advertisement for service promotion.

In some embodiments, the terminal may further perform the following target operations after generating the target media information: the terminal receives a target operation instruction which indicates to execute target operation on the target media information, wherein the target operation comprises one of the following operations: sharing operation, uploading operation and exporting operation; and responding to the target operation instruction, and executing the target operation on the target media information.

In actual implementation, for the generated target media file, operations such as sharing, uploading, exporting and the like for the target media information may be further performed, so that other users may perform other operations, such as viewing and the like, for the target media file.

For example, referring to fig. 18, fig. 18 is a schematic view of a target operation provided in an embodiment of the present application, where after a target media file is generated, a user clicks a "share" control shown by number 1, and may share target media information with other users having a social relationship with a current user; click number 2 shows that the "upload" control can save the target media file to the cloud; click number 3 shows that the "export" control can save the target media file to the local terminal in the target format.

The target operation executed aiming at the target media information can effectively increase the applicable scenes of the target media information.

In some embodiments, before generating the target media information, the terminal may further determine the target object by: responding to the permission setting instruction, and displaying at least one object having a social relation with the current object; in response to an object selection operation for at least one object, the selected object is determined as a target object.

In actual implementation, when a target operation performed on target media information has a corresponding target object, corresponding permissions may be set for one or more other objects having a social relationship with the current object for different responses to the target operation before generating the target media information. If the sharing operation is performed on the target media information containing the encrypted content, different permissions may be set for the object indicated by the sharing operation, if an object shows the target media information at a corresponding terminal, the encrypted target content is still in an invisible state, and if some objects show the target media information at corresponding terminals, the encrypted target content may be in a visible state. That is, a white list or a black list may be set for other objects having a social relationship with the current object.

For example, referring to fig. 19, fig. 19 is a schematic diagram of an object permission setting interface provided in an embodiment of the present application, a current object clicks a "permission setting" function item, the permission setting interface shown in the diagram is presented, number 1 in the interface shows a plurality of other objects having a social association relationship with the current object, and the current object may set, for each object shown by number 1, whether encrypted content in media information can be normally presented. The current object adds the "object 3", "object 5" and "object 7" to the rights white list, so that when the object 3 displays the target media information corresponding to the media information, the encrypted content can be controlled to be in a visible state (i.e. normally displayed).

Accordingly, in some embodiments, after generating the target media information, the terminal may further control the presentation state of the target media by: when a first sharing instruction is received, wherein the first sharing instruction is used for indicating that the target media information is shared to the target object, the target media information is shared to a first terminal of the target object, so that when the first terminal displays the content in the target media information, the content is controlled to be in an invisible state; when a first sharing instruction is received, the first sharing instruction is used for indicating that the target media information is shared to other objects except the target object in at least one object, the target media information is shared to second terminals of the other objects, and therefore when the second terminals display the content in the target media information, the content is controlled to be in a visible state.

In actual implementation, when the target operation for the target media information is a sharing operation, if the determined target object for receiving the target media information is in a permission blacklist set by the current object for the media information, and the target object displays the target media information through a terminal where the target object is located, a floating layer for covering the target content is displayed, namely the target content is in an invisible state at the moment; when the target object is in a permission white list set by the current object for the media information, the target object displays the target media information through the terminal where the target object is located, and when the target media information is displayed, the target content is normally displayed, namely the target content is in a visible state.

By applying the embodiment, the position of the target content in the media information is determined in various positioning modes in the display process of the media information, so that the searching efficiency of the target content is improved, and the encryption efficiency is improved; the method comprises the steps that a content encryption instruction for indicating that all or part of target content of media information is encrypted is responded, and the target content is encrypted, so that encryption operation for part of content in the media information can be realized, the accuracy of encrypted content is improved, and the accuracy of encryption operation is improved; and generating target media information based on the content generation instruction, and controlling the encrypted content to be in an invisible state in a floating layer covering mode in the target media information display process, so that the human-computer interaction experience can be improved on the premise of ensuring the data security.

Next, a method for processing media information provided in the embodiments of the present application is described by taking a terminal as a receiving end embodiment of target media information. Referring to fig. 20, fig. 20 is a schematic flowchart of a method for processing media information according to an embodiment of the present application, where the method for processing media information according to the embodiment of the present application includes:

step 301, a receiving end acquires target media information, wherein the target media information comprises a plurality of continuous content units, and part of content in the content units is encrypted by adopting a floating layer covering mode.

In actual implementation, the target media information acquired by the terminal comprises a plurality of continuous content units, and the existing part of the content is encrypted. Taking the example that the target media information is a video containing encrypted content, the corresponding content unit may be an image frame, a shot, a scene, etc.; taking the example where the target media information is a multi-page document containing encrypted content, the content units may be paragraphs, pages, etc.

And step 302, responding to a display instruction aiming at the target media information, and displaying the content included in the target media information.

In practical implementation, the terminal deploys a client for playing the media information, and when receiving a display instruction for the target media information, the terminal displays the target media information in the media information interface. The manner of receiving the display instruction may be that the user triggers a display function item for displaying the media information.

And step 303, controlling the partial content to be in an invisible state when the encrypted partial content is displayed.

In practical implementation, when the terminal displays the encrypted partial content in the process of displaying the target media information, the floating layer is displayed to shield the encrypted content, namely, the partial content is controlled to be in an invisible state.

In some embodiments, the partial content may be controlled to be in a visible state by: displaying an identity verification function item; and in response to the identity verification operation for the current object triggered based on the identity verification function item, when the identity verification for the current object passes, the control part of the content is switched from the invisible state to the visible state.

In actual implementation, because the authority setting is performed on the relevant object (user) receiving the target media information when the target media information is generated, the encrypted content can be normally displayed when the object in the authority white list displays the target media information through the terminal. That is, when the object displaying the target media information is in the permission white list, the target media information can be normally displayed. In practical application, in order to further ensure the security of the media information, the receiving end may check the identity of the current object corresponding to the receiving end before displaying the media information, and the specific check mode may be a bottom-layer check based on user authorization or a check based on user information input. When the identity verification is passed, the target media information can be normally displayed, namely, the control part of the content is switched from the invisible state to the visible state.

Exemplarily, referring to fig. 21, fig. 21 is a schematic diagram of an identity verification function interface provided in this embodiment, where number 1 in the diagram shows an object, media information corresponding to "2020 conference end" is shown in a corresponding terminal, when content corresponding to a time point "1: 18" is shown, a floating layer is displayed to shield related content and prompt that "the content is encrypted", at this time, the object number 1 may perform corresponding identity verification processing by clicking an "identity verification" function item shown by number 2 in the display interface, click the "identity verification" function item, present a verification interface shown by number 3, that is, by scanning a two-dimensional code in the verification interface, send identity confirmation information to a publisher of the media information (a publisher avatar shown by number 4), after the identity verification passes (the publisher has a social association relationship with the object shown by number 1), the content corresponding to the time point of "1: 18" is controlled to be in a visible state (i.e., the normally presented content shown by the number 4). When the identity verification fails, a message prompt interface can be popped up, namely 'no right to check the content and please contact the publisher for processing'.

The above-mentioned mode of carrying out identity verification to the object of receiving the target media information can avoid the content of encryption to be propagated and revealed, promotes the security of encrypting the content.

By applying the embodiment, when the target media message containing the protected content is displayed, the target object is subjected to corresponding identity verification, so that the target object can be accurately screened, the protected content can be prevented from being spread and leaked, and the safety of the protected content is improved.

Next, an exemplary application of the embodiment of the present application in a practical application scenario will be described.

In the related art, video protection encryption is divided into three schemes, namely downloading prevention, screen recording prevention and anti-theft chain. The anti-download scheme mainly adopts a file slicing technology, namely, an uploaded video is cut into countless small segments, and different encryption algorithms are adopted in each small segment. With this encryption algorithm, even if the video is downloaded, it cannot be played out completely because the critical data order of the video has been disturbed.

However, for the screen recording prevention scheme, modes such as setting a marquee and prohibiting a browser from recording a screen are mainly adopted to prevent screen recording, and although screen recording prevention cannot be achieved completely, great screen recording difficulty is increased for pirates. However, the educational institution or the teacher individual can add the institution mark or the trademark to the live video to help the video-stealing person to publicize, and it needs to be noted that the trademark and the institution mark cannot be clear or cannot be absent. The anti-theft chain scheme mainly limits the identity of a watching user and effectively restrains pirated videos through the self-defined functions of a live background, such as white list setting, identity authentication watching, payment watching and the like. Meanwhile, in order to prevent people who have pirated videos in watching users from watching live videos, the users need to check identities, namely, the videos generate different addresses every millisecond, and each address is allowed to be watched once, so that the videos are prevented from being illegally spread in the process of playing.

In the scheme, the related video encryption technology only aims at the whole video file and cannot encrypt or smear partial information of the content in the video file; in addition, the video encryption technology cannot be positioned in specific video content through key information mentioned in the conference process, and smearing protection of partial information is implemented.

Based on this, the embodiment of the present application provides a method for processing media information, where the method is a method for protecting video information in an encrypted smearing manner, where the video information may be a meeting record, a teacher classroom video, and the like. The video information can be obtained by encrypting and smearing the video content or the image-text information content appearing in the video before the user generates the cloud storage record by recognizing the voice key or the subsequent video in the live conference scene, and finally synthesizing a new video record again and uploading the new video record to the cloud so that the user can protect the content information of the video in the subsequent transmission/review content.

Next, a usage scenario and a processing flow of the processing method of media information will be explained. When a user uses video conference (live broadcast) software, keyword eyes such as 'secret', 'important', 'key' and communicated semantic comprehension, which are mentioned in the process of the user, for example, a person on the conference mentions that the 'sensitive data cannot be uploaded', and the like can be identified, after the video conference is finished, the user can locate the keyword pages of the keyword eyes through the generated video records temporarily stored in the cloud, and directly encrypt or smear part of information in the whole video page of the current frame; or the user can smear the page or part of information to be encrypted by adjusting the progress bar of the video conference record, in the encryption process, the user can cancel all encryption/smearing in a single step or cancel all encryption/smearing by one key, finally, the record generation button is clicked, the current video conference record can be stored in the cloud again (if the user does not perform any operation, the video conference record can be directly stored in the cloud within a limited period), and the video conference record can be transmitted or shared after being stored in the cloud.

Next, an interactive flow of the processing method of media information is explained from the product side. Referring to fig. 22, fig. 22 is a flowchart of a processing interface of media information provided in an embodiment of the present application, where a video played in fig. 1 is a video conference record that has been temporarily stored in a cloud, the video pauses at a position of a keyword that a user has said in a conference process or automatically locates at a position where the video pauses according to semantic understanding in the conference process, and a smearing position can be confirmed by dragging a video playing progress bar; fig. 2 shows that after the user clicks the "encrypt" button, the video file is controlled to be in an encrypted state, and the "one-key encrypt" (automatic encrypt in the foregoing) and "smear encrypt" function items are presented in the video playing interface; after the click operation of the one-key encryption button is responded, the presentation page to which the content at the position in the video belongs is encrypted, all frame pictures related to the encrypted presentation page are encrypted, and at the moment, the 'withdrawal' state is activated, and the user can withdraw the operation by returning to the previous step; after the user clicks 'finish', the video file is encrypted successfully, a 'cancel' button appears, and the user clicks to indicate that the encryption before the one-key cancellation is carried out; at the moment, the user can also click on encryption storage, and then the current video record can be stored; when a user drags a playing progress bar of the video to another playing time point '01: 18' (another positioning position) to prepare to start encryption; responding to the click operation of the encryption button in the figure (2) again, controlling the video information to be in an encryptable state, and presenting the one-key encryption function item and the smearing encryption function item in a playing interface of the video information; in fig. 4 is shown that in response to a click operation for the "paint encrypt" button, a "pencil" icon is presented, which can be clicked or manually painted to cover important information; in response to the click operation of the 'completion' button, the video information is successfully encrypted, a 'cancel' button is presented, and in response to the click operation of the 'cancel' button, the encryption operation of the video information can be cancelled by one key; in addition, in response to a click operation for "save encrypted", the current video information may be saved. In response to the click operation for 'encryption saving', encrypted video information (also called target video information) is generated and stored in the cloud, then operations such as sharing and exporting can be performed on the encrypted video information, a user can select a user to check the permission in the sharing process, and an open permission can be set for people who do not need to keep secret to share, namely, the encryption is closed.

Next, from the aspect of technical implementation, a hardware environment, implementation logic, and a data processing flow of the media information processing method provided in the embodiment of the present application are described. Referring to fig. 23, fig. 23 is a schematic diagram of a media information processing method according to an embodiment of the present application.

Firstly (the first step in the figure), in a video conference (live broadcast) client side of any mobile terminal or desktop terminal, in the live broadcast video conference process, keywords such as 'secret', 'important', 'key' and the like mentioned by a speaker are automatically identified through an intelligent voice identification technology; after the initial video conference record is generated, a key video page (one or more continuous frame images) where the key words are located is automatically searched according to Artificial Intelligence (AI), and besides, the key frames of the page where the key information is located are selected according to semantic understanding identification in all conference videos of an AI algorithm. After the corresponding keyword is recognized, modeling is carried out on the time sequence information by utilizing an HMM model in an acoustic model GMM-HMM, and after one state of the HMM is given, the GMM models the probability distribution of the speech feature vector belonging to the state. By recognizing pronunciation, Chinese is the correspondence between pinyin and Chinese characters, and English is the correspondence between phonetic symbols and words. Finding out corresponding Chinese characters (words) or words in a dictionary according to phonemes identified by the acoustic model, establishing a bridge between the acoustic model and the language model, connecting the acoustic model and the language model, identifying video segments for speaking the keywords in the video information in the generated conference record, positioning, and pausing to display a current key page (namely jumping to a key frame corresponding to the keywords).

Secondly (the second step in the figure), the key page in the video information is converted into a plurality of frames of pictures with time sequence relation, and the playing progress bar of the video information is adjusted to the time point of the key page. For encryption of a complete page, pictures can be directly encrypted according to an encryption algorithm, and picture and text information such as pictures, presentation files, labels and the like in a video live conference with the same page is automatically combined for encryption, specifically, the scalable and lightweight video encryption algorithm based on H.264/AVC (video compression format) aims at diversity formed by video application scenes, safety requirements and calculation resource differences, and is a scalable and lightweight video encryption algorithm which can meet most media application platforms. In consideration of the security of the encryption algorithm, the encryption speed, the mutual restriction relationship among several factors such as compression ratio and the like, the key data such as the intra-frame prediction mode, the motion vector difference and the brightness quantization transformation coefficient are encrypted by using the standard encryption algorithm. The algorithm can realize the encryption effect of multiple levels from low to high according to the difference between the security requirement level and the computing resource level in practical application, the compression ratio is not changed greatly, the computing complexity is relatively low, and certain operability is realized. In the encryption process, the single frames are encrypted, the same frames can be combined and encrypted, the encrypted frames are displayed as that the content is encrypted, or an encrypted watermark of a complete page is provided, and the user is informed that the content is encrypted through the display of characters and graphs.

In addition, the encryption of the key page for partial information can erase or block any characters and graphics on the pictures, the presentations and the labels in a stroke or other encrypted covering modes through real-time smearing processing so as to protect the contents of the pictures, the presentations and the labels. The essence of smearing is that the information which is not required to be displayed in the video is supplemented, the video supplementing method is based on an optical flow technology, the color and the optical flow can be synthesized, the color is transmitted along the track of the optical flow, the time continuity of the video is improved, and therefore the memory problem is relieved, and high-resolution output is achieved. The method based on the optical flow is adopted, the edge of a moving object is extracted and supplemented, and then the optical flow is supplemented by taking the optical flow edge as a guide. Since not all missing regions in the video can be completed by this method, researchers have introduced non-local optical flow, enabling video content to propagate over motion boundaries.

Meanwhile, for voice information in a video, related encryption needs to be performed as well, specifically, voice identification is performed on the voice information to obtain voice content, voice shielding is performed on the content of the whole page, the point information or short message is encrypted for encryption of a single piece of information, namely, data is encrypted, namely, compression coding is performed through a mobile terminal and a communication network, RPE-LTP coding is performed through PCM coding and a vocoder, and finally, voice after compression coding is output.

And thirdly (the third step in the figure), after partial information in the video content is encrypted or smeared, the real-time processing is reintegrated into a new video record, and the encrypted video information can be stored in the cloud again in a mode of returning to the previous step for revocation or revoking all encryption by one key.

Finally (fourth step in the figure), for the sharing operation of the generated encrypted video information, encrypted sharing and non-encrypted sharing can be selected, and in the sharing process, the encrypted video information stored in the cloud is encoded and converted into corresponding links. For a target object (user) indicated by a sharing operation requiring an open right, the video converts the revoked encrypted content into a link, and a specific revocation encryption mode is reverse coding for the situation of previous encryption.

By applying the embodiment of the application, partial information of the content in the video file can be encrypted or smeared, including but not limited to image and text information such as pictures, presentations, labels and the like, so that the video recording information is protected from being stolen or used for other purposes in subsequent transmission and sharing.

According to the embodiment of the application, the mode of encrypting and smearing the generated video conference record in the conference process and after the conference process is adopted, so that part of information in the video content, including but not limited to picture, presentation, annotation and other image-text information, is encrypted or smeared in the video recording Chinese on the temporary cloud, and the video recording information is protected from being stolen or used for other purposes in the transmission and sharing after being stored in the cloud again.

In the embodiment of the present application, related data such as user information is referred to, when the embodiment of the present application is applied to a specific product or technology, user permission or consent needs to be obtained, and collection, use and processing of the related data need to comply with relevant laws and regulations and standards of relevant countries and regions.
