Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, a first message may also be referred to as a second message, and similarly, a second message may also be referred to as a first message, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

The application aims to provide a video query method, wherein when a server receives a query request, the server can find at least one corresponding video segment according to the query request and determine at least one hidden time segment corresponding to the query request. If the user identity is determined to be used for indicating that the hidden video is allowed to be checked according to the user identity, the video segments which are not matched with the hidden time periods in the at least one video segment and the video segments which are matched with the at least one hidden time period and are provided with the hidden marks are returned to the query end for sending the query request, so that the query end displays the video segments which are not matched with the hidden time periods and the video segments which are matched with the at least one hidden time period and are provided with the hidden marks in a distinguishing mode.

On the one hand, the server returns the hidden video clips (i.e. the video clips which are matched with at least one hidden time period and are provided with the hidden marks) in the authority range to the inquiring party based on the user identity of the inquiring party, so that the hidden video with privacy in the video clips can be ensured not to be revealed.

Referring to fig. 1, fig. 1 is a network architecture diagram of a video query system according to an exemplary embodiment of the present application.

The networking of the video inquiry system comprises the following steps: object recognition device, client and server.

The object recognition device is deployed in the monitoring area and is used for recognizing whether a specified object appears in the monitoring area and notifying the client when the specified object appears. In addition, the object recognition device can also send the video collected in the monitoring area to a server for storage.

The object recognition device may be a physical device such as a monitoring device with object recognition functionality (the monitoring device is also referred to as a monitoring point such as a camera, etc.). Of course, the object recognition device may also be a virtual device, such as a virtual device composed of a monitoring device and an object recognition server. The monitoring device is used for collecting images and sending the images to the object recognition server, and the object recognition server recognizes objects from the images.

In addition, it should be noted that the above objects may include people, vehicles, animals, etc., and the objects are only exemplarily described herein and are not specifically limited thereto.

And the client is used for providing the functions of setting the hidden time period and inquiring the video recording section for the user.

The server is used for storing the video segments collected by the object recognition equipment, storing the hidden time segments set by the user, returning the video segments to be queried by the user when the user queries the video segments, and the like.

The video query method provided by the application is described in detail below from both the setting of the hidden time period and the query of the video period.

1. Setting of hidden time periods

In this application, a client provides multiple types of roles for a user, such as a first type of role and a second type of role. Wherein a first type of character (also referred to as a first type of user) has the right to set a hidden time period and a second type of character (also referred to as a second type of user) does not have the right to set a hidden time period. For example, the first type of role may be an administrator role. The second type of role may be an operator role. Of course, other roles are possible, which are only exemplary and not specifically limited.

The setting of the hidden time period provided in the present application will be exemplarily described below using the first type of role as an administrator and the second type of role as an operator.

The administrator has the right to set the hidden time period, and the operator does not have the right to set the hidden time period.

Specifically, after the user logs into the system, if the user logs into the client with the administrator identity, the client will display the administrator page to the user. The administrator page is provided with an option for triggering the setting of the hidden time period, and the setting of the hidden time period can be completed when the administrator triggers the option.

If the user logs in the client with the operator identity, the client displays an operator page to the user. The operator page does not have an option to trigger setting the hidden time period, so the operator cannot set the hidden time period.

In an alternative implementation, the object recognition device may send a prompt message to the client when detecting that the specified object is present in the monitoring area. After receiving the prompt information displayed by the client, the administrator can set a hidden time period according to the video collected by the object recognition device.

When the method is realized, the information of the appointed object is preconfigured on the object recognition equipment, the object recognition equipment collects the information of the target object appearing at the monitoring point, whether the information of the target object hits the recorded information of the appointed object or not can be detected, and if the information of the target object hits, the target object is determined to be the appointed object.

When the object is a person, the information of the specified object is a face image or a face feature of the specified person, and the information of the target object is a face image or a face feature of the person appearing at the monitoring point.

When the object is a vehicle, the information of the specified object is the license plate number and the color of the specified vehicle, and the information of the target object is the license plate number and the color of the vehicle appearing at the monitoring point.

In this embodiment of the present application, after determining that the target object is a specified object, the object recognition device may send a prompt message to the client. After receiving the prompt information, the administrator of the client can set the hidden time period based on the video returned by the object recognition device (such as according to the time length of the target object appearing at the monitoring point).

For example, the monitoring area is a conference room. The designated object is a corporate manager. And after the object identification equipment of the conference room detects that the manager enters the conference room, a reminding message is sent to the client. The administrator may set the duration of the meeting at the manager to be a hidden time period, or the duration occupied by important meeting content in the meeting to be a hidden time period.

The administrator sets a correspondence between the hidden time period and the monitoring point identifier (i.e., the identifier of the monitoring device in the monitoring area) on the administrator page. And the client generates a hidden video setting request according to the corresponding relation between the hidden time period and the monitoring point mark, and sends the hidden video setting request to the server.

After receiving the hidden video setting request, the server can record the corresponding relation between the hidden time period and the monitoring point mark.

In another alternative implementation, the object recognition device may send a prompt to the client when detecting that the monitoring point presents the specified object. The prompt message comprises: the monitoring points identify and specify information of the object. The client may set the hidden time period based on information of the specified object returned by the object recognition apparatus.

For example, the client may determine a residence time of the specified object at the monitoring point based on the video of the monitoring point returned by the object recognition device, and set the hidden time period according to the residence time.

For another example, the object recognition device further has a voice recognition function, and the object recognition device transmits the recognized specified vocabulary to the client. For example, when the object recognition device recognizes "important content", the "important content" is returned to the client, and the client sets the hidden time period according to the receiving time of the vocabulary.

The client automatically setting the hidden period is only exemplarily described here, and is not particularly limited.

After determining the hidden time period, the client can send a hidden video setting request to the server. The hidden video setting request includes: hiding the corresponding relation between the time period and the monitoring point mark.

2. Query of video segments

Referring to fig. 2, fig. 2 is a flowchart of a video query method according to an exemplary embodiment of the present application, where the method may be applied to a server and may include the following steps.

Step 201: the server receives a query request; the query request includes at least: a user identity mark;

the query request may further include: the target monitoring point identification to be queried, the target query time period to be queried and other information. The query request is only exemplarily described here, and is not specifically limited thereto.

When the user wants to inquire the video segment, the user can input the information such as the target monitoring point identification to be inquired, the target inquiring time period to be inquired and the like on the client

The client may acquire the user identity when the user logs into the client, or may generate the user identity based on the identity used/displayed when the user logs into the client.

The client may generate a query request based on the target monitoring point identifier, the target query time period, and the user identity input by the user, and send the generated query request to the server.

Step 202: the server searches at least one corresponding video segment according to the query request; the server determines at least one hidden time period corresponding to the query request.

In implementation, the query request may further include: the target monitoring point to be queried is identified and queried for a time period.

During inquiry, the server stores video segments collected by each monitoring point and video time corresponding to each video segment. The recording time refers to a time period formed by the starting time and the ending time of one recording section.

The server can search at least one video segment with video time in the target inquiry time period and corresponding to the target monitoring point identification in the acquired video segments.

In the implementation of the present application, as can be seen from the above description, the corresponding relationship between the monitoring point identifier and the hidden time period may be recorded on the server.

The query request may also carry the target monitoring point identifier to be queried.

When determining at least one hidden time period corresponding to the query request, the server may search for the at least one hidden time period corresponding to the target monitoring point identifier in the corresponding relationship between the monitoring point identifier and the hidden time period, as the at least one hidden time period corresponding to the query request.

Step 203: if the server determines that the user identity is used for indicating permission to view the hidden video according to the user identity, the video segments which are not matched with the hidden time periods in the at least one video segment and the video segments which are matched with the at least one hidden time period and set with the hidden mark are returned to the query end for sending the query request, so that the query end displays the video segments which are not matched with the hidden time periods and the video segments which are matched with the at least one hidden time period and set with the hidden mark in a distinguishing mode.

Step 203 is described in detail below by steps 2031 to 2032.

Step 2031: the server sets a hidden mark in the at least one video segment.

Step 2031 is described in detail below by steps A1 to A2.

Step A1: and the server determines at least one target video clip matched with the hidden time period in the searched at least one video clip.

Here, it may be that at least one target video clip matching with the partial concealment period is determined, for example, in the case that, in the at least one concealment period, a video clip corresponding to the partial concealment period cannot be returned to the query for display, then only the target video clip matching with another partial concealment period other than the partial concealment period needs to be determined; all target video clips can be determined according to each hiding time period, wherein all target video clips comprise target video clips which are determined for each hiding time period and matched with the hiding time period.

When the method is realized, for the searched video clips with intersections with the hidden time period, determining the target video clip matched with the hidden time period from the video clips according to the hidden time period.

The found video segments that have intersections with the hidden time segments include two cases.

In the first case, the recording time of the recording section and the hidden time section have an intersection, and the recording time of the recording section is included in the hidden time section. For this case, the server may directly treat the video segment as a target video segment that matches the hidden time segment.

In the second case, the recording time of the recording section and the hidden time section have an intersection, and the recording time of the recording section is not included in the hidden time section. For this case, the server may divide the video segment based on the start time or the end time of the hidden time period, obtain a plurality of video segments, and use the divided video segments within the hidden time period as target video segments.

Example 1, assume that the target monitoring point in the query request is monitoring point 1 and the target query time period is 2020-06-01 08:00:00 to 2020-06-01-12:00:00.

Assume that the hidden time period corresponding to the monitoring point 1 is 2020-06-01 09:20:00 to 2020-06-0110:20:00.

After receiving the query request, the server may search for at least one video segment of the video time within the target query time period (i.e. 2020-06-01 08:00:00 to 2020-06-01 12:00:00) and corresponding to the target monitoring point identifier (i.e. monitoring point 1) in the acquired video segments, where the searched video segment is shown in table 1.

Video segment	Start time	End time
			Video segment 1	2020-06-01T08:00:00.000Z	2020-06-01T09:10:00.000Z
Video segment 2	2020-06-01T09:10:00.000Z	2020-06-01T10:10:00.000Z
			Video segment 3	2020-06-01T10:10:00.000Z	2020-06-01T11:10:00.000Z
Video segment 4	2020-06-01T11:10:00.000Z	2020-06-01T12:00:00.000Z

TABLE 1

The server may then have video segments, in this example video segment 2 and video segment 3, that intersect with the hidden time segment.

For video segment 2, in accordance with the second scenario described above, the server may divide video segment 2 into segments 21 of 9:10-9:20 and segments 22 of 9:20-10:00 based on the start time of the hidden time period (i.e., 9:20). Since segment 22 is within the hidden period, the server may determine that segment 22 is the target video segment.

For video segment 3, in accordance with the second scenario described above, the server divides video segment 2 into 10:10-10:20 segments 31, 10:20-11:10 video segments 32 based on the end time of the hidden time period (i.e., 10:20). Since segment 31 is within the hidden period, the server may determine that segment 31 is the target video segment.

The divided fragments are shown in table 2.

Video segment	Start time	End time
			Video segment 1	2020-06-01T08:00:00.000Z	2020-06-01T09:10:00.000Z
Fragment 21	2020-06-01T09:10:00.000Z	2020-06-01T09:20:00.000Z
			Fragment 22	2020-06-01T09:20:00.000Z	2020-06-01T10:10:00.000Z
Fragment 31	2020-06-01T10:10:00.000Z	2020-06-01T10:20:00.000Z
			Fragment 32	2020-06-01T10:20:00.000Z	2020-06-01T11:10:00.000Z
Video segment 4	2020-06-01T11:10:00.000Z	2020-06-01T12:00:00.000Z

TABLE 2

Step A2: and the server selects a target video clip to be returned from the at least one target video clip, and sets a hidden mark for the target video clip to be returned.

In an alternative implementation, the target video clip to be returned is all target video clips matching the hidden time period, and the server may set a hidden flag for all target video clips matching the hidden time period. Optionally, if the server determines all the target video clips according to each hidden time period in the at least one video clip that is found, where the all the target video clips include the target video clips that are determined for each hidden time period and that match the hidden time period, the target video clip to be returned may be the all the target video clips, and the server may set a hidden flag for the all the target video clips.

The hidden mark is used for enabling the inquirer to distinguish the hidden video clip and the common video clip in the video clip returned by the server, so that the inquirer can distinguish and display the hidden video clip and the common video clip.

Still taking the example of table 1 as an example, in such an implementation, the server may determine that fragments 22 and 31 are fragments to be returned and set hidden flags for fragments 22 and 31.

In another alternative implementation manner, the server may select, from the determined at least one target video clip, a target video clip that meets a preset video clip condition as the video clip to be returned, and set a hidden flag for the video clip to be returned.

Wherein, the preset video clip condition may include one or more of the following:

condition 1: the video grade of the video clip to be returned is lower than the preset video grade;

condition 2: matching the video grade of the video clip to be returned with the video grade corresponding to the user identity;

condition 3: the hidden time period corresponding to the video clip to be returned is set by the user indicated by the user identity;

condition 4: setting the user level of the user of the hidden time period corresponding to the video clip to be returned to be lower than or equal to the user level indicated by the user identity.

For condition 1:

the server can set different video levels for the acquired video segments according to factors such as importance of the video segments, and the lower the video level is, the lower the importance of video is. Regardless of the identity of the querying party, as long as the querying party is permitted to view the hidden video, the server may return the target video clips with video levels below the preset threshold to the querying party, but not return the target video clips with video levels above the preset threshold to the querying party. In other words, the service may return video clips of low importance to the querying party and not return video clips of high importance to the querying party.

For condition 2:

condition 2 achieves the goal that the user can only view hidden video clips of video levels that match the user's own level (i.e., video clips that match the hidden time period).

The server may set video levels for the video segments collected and different user levels for the user. In addition, the server pre-configures the video levels of the target video clips that can be viewed by each user level.

For example, video recording levels are configured as level a, level B, and level C, respectively. The user level is configured as a high-level manager, a medium-level manager and a general manager.

The video recording level corresponding to the user identity configured by the server is shown in table 3.

TABLE 3->

Assuming that the inquirer is a middle-level administrator, the server can select a video clip with a video level of B-C from at least one target video clip matched with each hidden time period as a video clip to be returned.

For condition 3:

the object achieved by condition 3 is that: when the user identity is used for indicating that the hidden video is allowed to be viewed, the user can view the video clip which is set by the user and is matched with the hidden time period.

For example, the example in example 1 is still taken as an example.

If the above hidden time periods 2020-06-01:20:00 to 2020-06-01:10:20:00 are set by the inquirer, then the determined segments 22 and 31 are determined to be video clips to be returned.

If the above-mentioned hidden time periods 2020-06-01:20:00 to 2020-06-01:10:20:00 are not set by the inquirer, it is determined that there is no video clip to be returned that matches the hidden time period.

For condition 4:

the object to be achieved by condition 4 is: the high-level user can view the video clips that match the hidden time period set by the low-level user.

For example, the example in example 1 is still taken as an example.

It is assumed that the above-described hidden time periods 2020-06-01:20:00 to 2020-06-01:10:20:00 are set by a middle-level administrator, and that the inquirer is a high-level administrator.

The server may determine that both the determined segment 22 and segment 31 are to be video clips to be returned.

It is further assumed that the above-described hidden time periods 2020-06-01:20:00 to 2020-06-01:10:20:00 are set by a senior manager, and that the inquirer is a senior manager.

Since the inquirer level is lower than the user level for setting the hidden time period, the server can determine that there is no target video clip matching the hidden time period that meets the inquirer's inquiry authority, so in this example, there is no video clip to be returned that matches the hidden time period.

Step 2032: if the user identity is determined to be used for indicating that the hidden video is allowed to be checked according to the user identity, the video segments which are not matched with each hidden time period in the at least one video segment and the video segments which are matched with the at least one hidden time period and set with the hidden mark are returned to the query end for sending the query request, so that the query end displays the video segments which are not matched with each hidden time period and the video segments which are matched with the at least one hidden time period and set with the hidden mark in a distinguishing mode.

When the method is realized, if the user identity meets a third condition and/or meets a fourth condition, determining that the user identity is used for indicating permission to view the hidden video;

the third condition includes: the user type corresponding to the user identity is a first type, or the user type corresponding to the user identity is a first type and the user identity meets the preset user condition;

the fourth condition includes: the user type corresponding to the user identity is of a second type, and the user level corresponding to the user identity is higher than a preset user level threshold.

Step 204: if the user identity is determined to be used for indicating to prohibit from viewing the hidden video according to the user identity, deleting all target video segments from the searched video segments and returning to a query end for sending the query request, wherein all target video segments comprise target video segments which are determined for each hidden time segment and are matched with the hidden time segment.

When the method is realized, if the user identity meets a first condition and/or meets a second condition, the server determines that the user identity is used for indicating to prohibit viewing of the hidden video;

The first condition includes: the user type corresponding to the user identity is the second type, or the user type corresponding to the user identity is the second type and the user level corresponding to the user identity is lower than a preset user level threshold;

the second condition includes: the user type corresponding to the user identity is a first type, and the user identity does not meet preset user conditions.

Wherein the first type of user has the right to set the hidden time period and the second type of user does not have the right to set the hidden time period. For example, the first type of user is an administrator and the second type of user is an operator. The first type user and the second type user are only exemplarily described herein, and are not particularly limited.

Various implementations of steps 2032 and 204 are described in detail below.

Case 1: a first type of user (e.g., an administrator) may view the hidden video and a second type of user (e.g., an operator) may not be allowed to view the hidden video.

In this case, when the server determines, according to the user identity, that the user identity is used to indicate whether to prohibit viewing of the hidden video or permit viewing of the hidden video, the server may determine a user type corresponding to the user identity, and if the user type is the second type, determine that the user identity is used to indicate that viewing of the hidden video is prohibited. At this time, the server may delete all the target video clips from the searched video clips and return the target video clips to the query end for sending the query request, where the all the target video clips include the target video clip that is determined for each hidden time period and matches the hidden time period.

If the user type is the first type, determining that the user identity is used for indicating that the hidden video is allowed to be checked, and returning the video segments which are not matched with all the hidden time periods and the video segments which are matched with at least one hidden time period and set with the hidden mark to the query end.

Case 2: the present application classifies the level of a first type of user (e.g., administrator), such as a senior administrator, a middle level administrator, a primary administrator, and the like.

When the first type of user satisfies the user condition, the server determines that the user is a user permitted to view the hidden video.

A second type of user, such as an operator, cannot view the hidden video.

In this case, the user conditions include: in at least one hidden time period, any hidden time period is set by a user indicated by the user identity; and/or setting the user level of the user in any hidden time period to be lower than the user level corresponding to the user identity.

Several implementations of determining the user identity as indicating whether to prohibit viewing of the hidden video or allow viewing of the hidden video based on the user identity are described below, which are exemplary only and not specifically limited.

The implementation mode is as follows:

the server may determine the user type to which the user identity corresponds.

1) If the user type is the first type, the server can detect whether each hidden time period is set by the user corresponding to the user identity. If any hidden time period (any hidden time period or any multiple hidden time periods) is set for the user corresponding to the user identity, determining that the user identity is used for indicating permission to view the hidden video, and returning a video segment which is not matched with each hidden time period and a video segment which is matched with at least one hidden time period and is provided with a hidden mark to the query terminal. If all the hidden time periods are not the user settings corresponding to the user identification, determining that the user identification is used for indicating to prohibit the hidden video from being checked.

For example, assume that there are two determined concealment periods of 9:00-10:00, 13:00-14:00, respectively.

The query time period carried in the query request is assumed to be 8:00-15:00.

Assuming that administrator 1 sets the hidden time period 9:00-10:00, administrator 2 sets the hidden time period 13:00-14:00.

Suppose the inquirer is administrator 1. Since the administrator 1 sets the hidden time period of 9:00-10:00, the administrator 1 allows viewing of the hidden video.

In addition, in combination with the above determination that the "the hidden time period corresponding to the video clip to be returned is set by the user indicated by the user id" in the manner of determining the video clip to be returned, since the administrator 1 sets the hidden time period 9:00-10:00, the server may set the hidden flag for the video clip 9:00-10:00, and the server may return the 9:00-10 with the hidden flag set to the device of the administrator 1: 00 video clips, 8:00-9:00 video clips, 10:00-13:00 video clips, and 14:00-15:00 video clips that do not match each hidden time period.

2) If the user type is the second type, the server deletes all target video clips from the searched video clips and returns the target video clips to the query end for sending the query request, wherein the target video clips are determined for each hidden time period and matched with the hidden time period.

Therefore, the manager can only inquire the hidden video corresponding to the hidden time period set by the manager, and can not inquire the hidden video corresponding to the hidden time period set by other managers. The operator cannot view the hidden video.

The implementation mode II is as follows:

The server may determine the user type to which the user identity corresponds.

1) If the user type is the first type, the server may detect whether the user level of the user setting each hidden time period is lower than or equal to the user level corresponding to the user identity. If the user level of the user setting any hidden time period is lower than the user level corresponding to the user identity, determining that the user identity is used for indicating permission to view the hidden video, and returning video segments which are not matched with all hidden time periods and video segments which are matched with at least one hidden time period and are provided with hidden marks to the query end. If the user level of the user setting all the hidden time periods is higher than the user level corresponding to the user identity, determining that the user identity is used for indicating to prohibit from viewing the hidden video, deleting all the target video clips from the searched video clips and returning the target video clips to the query end for sending the query request, wherein the target video clips are determined for each hidden time period and are matched with the hidden time period.

The query time period carried in the query request is assumed to be 8:00-15:00.

Assuming that there are 3 administrators, respectively administrator 1, administrator 2, and administrator 3, the three administrators are in order from high to low: administrator 1> administrator 3> administrator 2.

Suppose the inquirer is administrator 3. Since the level of the administrator 3 is higher than that of the administrator 2 who sets the hidden time period 13:00-14:00, the administrator 3 allows viewing of hidden videos.

In addition, in combination with the above manner of determining the video clip to be returned, the user level of the user setting the hidden time period corresponding to the video clip to be returned is lower than or equal to the user level indicated by the user id, and since the level of the administrator 3 is higher than the level of the administrator 2 setting the hidden time period 13:00-14:00, the server may set the hidden flag for the video clip 9:00-10:00, and the server may return the video clip 13:00-14:00 with the hidden flag, and return the video clip 8:00-9:00, the video clip 10:00-13:00, and the video clip 14:00-15:00, which are not matched with each hidden time period, to the device of the administrator 1.

Therefore, the hidden video segments corresponding to the hidden time segments set by the low-level administrator can be queried by the high-level administrator. The operator cannot view the hidden video.

And the implementation mode is three:

the server may determine the user type to which the user identity corresponds.

1) If the user type is the first type, the server detects whether each hidden time period is set by the user corresponding to the user identity, and detects whether the user level of the user setting each hidden time period is lower than the user level corresponding to the user identity.

If the user level of the user in any hidden time period is lower than the user level corresponding to the user identity, determining that the user identity is used for indicating permission to view the hidden video.

If all the hidden time periods are not set for the users corresponding to the user identification marks and the user levels of the users setting all the hidden time periods are higher than the user levels corresponding to the user identification marks, determining that the user identification marks are used for indicating to prohibit viewing of the hidden video.

The query time period carried in the query request is assumed to be 8:00-15:00.

Assuming that administrator 1 sets the hidden time period 9:00-10:00, administrator 2 sets the hidden time period 13:00-14:00. The level of administrator 1 is higher than the level of administrator 2.

Assuming that the querying party is administrator 1, since administrator 1 has set the hidden time period 9:00-10:00 and administrator 1 has a higher level than administrator 2 has set the hidden time period 13:00-14:00, the server may determine that administrator 1 allows viewing of the hidden video.

In addition, in combination with the above manner of determining the video clip to be returned, the user level of the user setting the hidden time period corresponding to the video clip to be returned is lower than or equal to the user level indicated by the user id, and the hidden time period corresponding to the video clip to be returned is set by the user indicated by the user id, since the hidden time period 9:00-10:00 is set by the administrator 1 and the level of the administrator 1 is higher than the level of the administrator 2 setting the hidden time period 13:00-14:00, the server may replace the video clip 13:00-14:00 with the hidden flag and the video clip 9:00-10 with the hidden flag to the device of the administrator 1: 00 video clips, 8:00-9:00 video clips, 10:00-13:00 video clips, and 14:00-15:00 video clips that do not match each of the concealment periods.

2) If the user type is the second type, determining that the user identity is used for indicating that the hidden video is forbidden to be checked.

Therefore, the hidden video segments corresponding to the hidden time segments set by the inquirer and set by the manager with the lower level than the inquirer can be inquired. The operator cannot view the hidden video.

Case 3: the first type of user allows viewing of the hidden video, or the first type of user allows viewing of the hidden video when a preset user condition is met.

The present application classifies the level of the second type of user (i.e., operator), such as high-level operators, medium-level operators, primary operators, etc. The second type users with the level higher than the preset user level threshold can only view the hidden fragments, and the second type users with the level lower than the preset user level threshold cannot view the hidden fragments.

Wherein, the user of the first type is allowed to view the hidden video, or the user of the first type is allowed to view the hidden video when the preset user condition is met. "as shown in case 1 and case 2 above, no further description is given here.

The following describes that a second type user with a level higher than a preset user level threshold can view the hidden fragments, and a second type user with a level lower than the preset user level threshold cannot view the hidden fragments. "implementation of the invention.

When the method is implemented, the server can determine the user type and the user level corresponding to the user identity, and if the user type is the second type and the user level is lower than a user level threshold, the server determines that the user identity is used for indicating that the hidden video is prohibited from being checked.

If the user type is the second type and the user level is greater than or equal to the user level threshold, determining that the user identity is used for indicating permission to view the hidden video.

Therefore, the hidden video can be checked by the operators with the level higher than the user level threshold, and the hidden video cannot be checked by the operators with the level lower than the user level threshold.

In addition, in the embodiment of the application, after receiving the video segments which are not matched with each hidden time period and the video segments which are matched with at least one hidden time period and provided with the hidden mark, the query terminal can distinguish and display the video segments which are not matched with each hidden time period and the video segments which are matched with at least one hidden time period and provided with the hidden mark.

For example, as shown in fig. 3, the query end may display video clips that do not match each hidden time period and video clips that match at least one hidden time period and have a hidden flag set by using the color of the video progress bar. For example, a progress bar corresponding to a video clip that matches at least one hidden time period and has a hidden flag set is light gray. The color of the progress bar corresponding to the video clips which are not matched in each hidden time period is dark gray and the like.

Of course, in practical application, the two different video clips can also be displayed in a distinguishing manner by presenting a prompt word on the video picture. For example, when video clips with all hidden time periods not matched are displayed, the video playing window simultaneously displays the word of "common video", and when video clips with at least one hidden time period matched and provided with a hidden mark are displayed, the video playing window simultaneously displays the word of "hidden video". The manner of distinguishing the display is described here by way of example only, and is not particularly limited.

In addition, in the embodiment of the present application, if the query end only receives the video segments which are not matched with each hidden time period, but does not receive the video segments which are matched with at least one hidden time period and set with the hidden mark, the video segments which are not matched with each hidden time period are displayed, and the content of the video segments which are matched with at least one hidden time period and set with the hidden mark is not displayed.

According to the description, on one hand, the server returns the hidden video clips within the authority range to the inquiring party based on the user identification of the inquiring party, so that the hidden video with privacy in the video clips can be ensured not to be revealed.

On the other hand, the method and the device also set the first type user level, the video level of the hidden video clip, the level of the second type user and the like, and return video clips of different levels to the inquiring party according to the user type and the level corresponding to the user identity, thereby realizing multi-level and fine-grained management of access rights.

Step 401: receiving a query request; the query request includes at least: a user identity mark;

step 402: searching at least one corresponding video segment according to the query request; determining at least one hidden time period corresponding to the query request;

step 403: if the user identity is determined to be used for indicating that the hidden video is allowed to be checked according to the user identity, the video segments which are not matched with each hidden time period in the at least one video segment and the video segments which are matched with the at least one hidden time period and set with the hidden mark are returned to the query end for sending the query request, so that the query end displays the video segments which are not matched with each hidden time period and the video segments which are matched with the at least one hidden time period and set with the hidden mark in a distinguishing mode.
