Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
The embodiment of the application provides a recording control method, which can be applied to a mobile terminal. The mobile terminal can be a smart phone, a tablet personal computer, a desktop computer, a smart watch, a camera, a recording pen and other devices with a recording function.
Referring to fig. 1, fig. 1 is a schematic flow chart of a recording control method according to an embodiment of the present application. The recording control method is applied to a mobile terminal, and can comprise the following steps:
For example, a user starts a recording application in a terminal, and before starting recording, the user needs to have both the runtime permission of a microphone and the application operation permission of OP _ READ _ AUDIO, and thus when the recording application starts, the user needs to perform permission check on the runtime permission and the application operation permission of the recording application.
For example, the run-time permission refers to a permission that a user does not need to authorize all applications at one time when the application program is installed, but can authorize a certain permission application in the use process of the application program. If the user uses a certain input method to input information in the instant communication program, the user needs to apply for the microphone authority, and if the user refuses, the user is only prohibited to input voice information, but text or picture information can be normally input.
For example, the authority generally has a difference between a common authority and a dangerous authority, the common authority system can automatically authorize, the dangerous authority usually relates to privacy and safety of a user, and the user needs to manually click authorization when applying for the authorization. For example, the object of the dangerous authority generally includes a calendar, a camera, an address book, location information, a microphone, a telephone, a sensor, a short message, and the like.
For example, for an android system, the system implicitly provides application operation (AppOps) authority management at the same time, the AppOps command is an executable program of the android system, and for example, the recording operation authority may be represented by OP _ READ _ AUDIO.
And 102, initializing the recording thread of the recording application program when the permission check results of the run-time permission and the application operation permission are allowed.
When the operation permission of the microphone is checked to be allowed and the recording operation permission of the microphone is detected to be allowed, initializing a recording thread of the recording application program to control the microphone to start to collect audio data.
And 103, monitoring the authority state change of the application operation authority in real time.
For example, when the recording thread of the recording application program is initialized, an operation right monitor for OP _ READ _ AUDIO operation is mounted on the recording thread, so that the operation right monitor monitors the right state change of the application operation right in real time. When the operation of the OP _ READ _ AUDIO is monitored as rejection, executing step 104; when the operation of the OP _ READ _ AUDIO is monitored as being permitted, step 105 is performed.
Before the user closes the recording application program, no matter the authority state of the application operation authority is changed into refusal or permission, the recording thread is not interrupted.
In some embodiments, the monitoring, in real time, a change in a right state of the application operation right includes:
monitoring the authority operating instruction of the application operating authority in real time;
and changing the authority state of the application operation authority according to the monitored authority operation instruction.
In some embodiments, the monitoring, in real time, the authority operation instruction of the application operation authority includes:
and determining the authority operation instruction of the application operation authority according to any one of the acquired designated characters, designated operation gestures and designated sounds input by the user.
For example, the user may set a first designated character corresponding to the "deny" permission operation instruction in advance in the terminal content, for example, the first designated character is "deny" or the like; and setting a second designated character corresponding to the permission operation instruction, wherein the second designated character is 'allow' and the like. For example, when a user uses a recording application program in a mobile terminal to record, in the recording process, when the user feels that contents related to secret information will appear in a recording scene, and some specific contents do not want to be recorded next, a first designated character is input into the mobile terminal, when the mobile terminal acquires the first designated character input by the user, an authority operation instruction of the recording operation authority is determined to be refused, and then the authority state of the application operation authority is changed from an original permission state to a refused state. For example, when the user feels that the content related to the secret information will not appear in the recording scene, and wants to continue recording, a second designated character is input into the mobile terminal, when the mobile terminal acquires the second designated character input by the user, the authority operation instruction of the recording operation authority is determined to be allowed, and the authority state of the application operation authority is changed from the previous refusal state to the permission state.
For example, the user may set a first designated operation gesture corresponding to a "deny" permission operation instruction in advance in the terminal content, where the first designated operation gesture is, for example: drawing an x on the touch screen of the mobile terminal, or continuously knocking at least 3 times on the touch screen of the mobile terminal, or pressing a volume reduction key and the like; and setting a second specified operation gesture corresponding to the permission operation instruction, for example, the second specified operation gesture is: drawing a check mark on the touch screen of the mobile terminal, or clicking and pressing the touch screen of the mobile terminal for a preset pressing time (such as 2 seconds), or pressing a volume increasing key, and the like. For example, when a user uses a recording application program in a mobile terminal to record, in the recording process, when the user feels that contents related to confidential information will appear in a recording scene, and some specific contents do not want to be recorded next, a first specified operation gesture (for example, drawing an x on a touch screen of the mobile terminal) is input into the mobile terminal, when the mobile terminal acquires the first specified operation gesture input by the user, a permission operation instruction of the recording operation permission is determined to be a rejection, and the permission state of the application operation permission is changed from an original permission state to a rejection state at this time. For example, when the user feels that the content related to the confidential information will not appear in the recording scene, and wants to continue recording again, a second specified operation gesture (for example, "√" is drawn on the touch screen of the mobile terminal) is input into the mobile terminal, and when the mobile terminal acquires the second specified operation gesture input by the user, the authority operation instruction for determining the recording operation authority is allowed, and the authority state of the application operation authority is changed from the previous refusal state to the allowed state at this time.
For example, the user may set a first designated sound corresponding to the "deny" permission operation command, for example, a "ticker" sound for short announcement, and a second designated sound corresponding to the "allow" permission operation command, for example, a "beep" sound for long announcement, in advance in the terminal content. For example, when a user uses a recording application program in a mobile terminal to record, in the recording process, when the user feels that contents related to secret information will appear in a recording scene, and some specific contents which do not want to be recorded next are recorded, a first specified sound is input into the mobile terminal, when the mobile terminal acquires the first specified sound input by the user, an authority operation instruction of the recording operation authority is determined to be refused, and then the authority state of the application operation authority is changed from an original permission state to a refused state. For example, when the user feels that the content related to the secret information will not appear in the recording scene, and wants to resume recording, the second designated sound is input into the mobile terminal, and when the mobile terminal acquires the second designated sound input by the user, the authority operation instruction for determining the recording operation authority is allowed, and at this time, the authority state of the application operation authority is changed from the previous refusal state to the permission state.
In some embodiments, the monitoring, in real time, the authority operation instruction of the application operation authority includes:
in the recording process, when the recording content is detected to have the preset keyword, determining the authority operation instruction of the application operation authority as a rejection instruction.
For example, the preset keyword may be a keyword for authenticating confidential information or sensitive content in a recording scene. For example, many conferences generally require a meeting record to be written after the meeting, and generally for the convenience of writing a meeting record later, the meeting record writer can record the meeting content, but some speakers mentioned in the meeting only want conference participants to hear at the meeting site, but do not want the content to be recorded or to be transmitted outside, and the speakers often do some language suggestion, such as "speak something with others but do not transmit it", "the content below", etc., before speaking the confidential information or sensitive content, so that the rejection instruction can be responded to by presetting a keyword. For example, the preset keyword may be "don't transfer", "confidential", "secret", or the like, and during the recording process, when the preset keyword is detected to appear in the recorded content, the permission operation instruction of the application operation permission is determined to be a refusal instruction, and then the permission state of the application operation permission is changed from the original permission state to the refusal state.
For example, when the user wants to resume recording, the user may input any one of a second designated character, a second designated operation gesture, and a second designated sound corresponding to the "permission operation instruction to determine that the permission operation instruction of the recording operation permission is permitted, and then the permission state of the application operation permission is changed from the previous refusal state to the permission state.
For example, a second preset keyword corresponding to an "allow" permission operation instruction may be preset, and when the second preset keyword is detected to appear in the recorded content, the permission operation instruction applying the operation permission is determined to be the allow instruction.
And 104, if the permission state is monitored to be changed into the refusal state, writing preset data into a cache region corresponding to the recording thread in the recording time period in which the permission state is changed into the refusal state.
In some embodiments, the preset data is null data or specified audio.
For example, when the preset data is empty data, if it is monitored that the permission state is changed into rejection, the empty data is written into the cache area corresponding to the recording thread within the recording time period in which the permission state is changed into rejection. That is, when the operation of the OP _ READ _ AUDIO is rejected, the recording thread writes null data into the Buffer (Buffer). By writing in the empty data, the storage pressure of the cache area can be reduced, and the specific content can be guaranteed not to be recorded in the recording time period when the permission state is changed into rejection under the condition that the recording thread is not interrupted.
For example, when the preset data is the designated audio, if it is monitored that the permission state is changed into rejection, the designated audio is written into the cache region corresponding to the recording thread within the recording time period in which the permission state is changed into rejection. That is, when the operation of the OP _ READ _ AUDIO is detected as rejection, the recording thread writes the designated AUDIO into the Buffer. For example, the designated audio may be a designated piece of music, a disturbing audio, or a certain piece of speech recorded in advance by the user, etc. By writing in the specified audio, the specific content can be ensured not to be recorded in the recording time period when the authority state is changed into the refusal state under the condition that the recording thread is not interrupted, and the continuity of the audio can be ensured when the finally output recording segment is played.
And 105, if the permission state is monitored to be allowed, writing the real audio data acquired by the recording application program into a cache region corresponding to the recording thread in the recording time period in which the permission state is allowed.
And only when the permission state is monitored to be allowed, the real audio data acquired by the recording application program is written into the cache region corresponding to the recording thread in the recording time period when the permission state is allowed, so that certain specific contents related to secret information or sensitive contents are filtered. That is, when the operation of the OP _ READ _ AUDIO is monitored to be allowed, the recording thread writes the real AUDIO data into the Buffer.
In some embodiments, the method further comprises:
and outputting a recording fragment comprising the preset data and the real audio data after the thread of the recording application program is finished.
For example, when the preset data is empty data, after the thread of the recording application is finished, the output recording segment may include only real audio data acquired by the recording application within the recording time period in which the permission state becomes allowable.
For example, when the preset data is a preset audio, after the thread of the recording application is finished, the output recording segment may include the preset audio and real audio data acquired by the recording application within the recording time period in which the permission state becomes allowed.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the recording control method provided in the embodiment of the present application, when the recording application is started, the permission check is performed on the run-time permission and the application operation permission of the recording application; when the permission check results of the operation permission and the application operation permission are allowed, initializing a recording thread of the recording application program; monitoring the authority state change of the application operation authority in real time; if the permission state is monitored to be changed into refusal, writing preset data into a cache region corresponding to the recording thread in the recording time period in which the permission state is changed into refusal; and if the permission state is monitored to be changed into permission, writing the real audio data acquired by the recording application program into the cache region corresponding to the recording thread in the recording time period when the permission state is changed into permission. According to the method and the device, under the condition that the recording thread is not interrupted, whether the specific content is recorded or not is controlled in real time according to the monitored authority state change of the application operation authority, and the information safety is improved.
The embodiment of the application further provides a recording control device, the recording control device can be integrated in the mobile terminal, and the mobile terminal can be a device with a recording function, such as a smart phone, a tablet computer, a desktop computer, a smart watch, a camera and a recording pen.
