The application aims to provide a video query method, and when a server receives a query request, the server can search at least one corresponding video segment according to the query request and determine at least one hidden time segment corresponding to the query request. And if the user identity is determined to be used for indicating that the hidden video is allowed to be viewed according to the user identity, returning the video segments which are not matched with the hidden time periods and the video segments which are matched with the hidden time periods and provided with the hidden marks in the at least one video segment to an inquiry end for sending the inquiry request, so that the inquiry end displays the video segments which are not matched with the hidden time periods and the video segments which are matched with the hidden time periods and provided with the hidden marks in a distinguishing manner.

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

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

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

The object identification device is deployed in the monitoring area and used for identifying whether a specified object appears in the monitoring area or not and informing the client when the specified object appears. In addition, the object recognition device can also send the video collected in the monitoring area to the server for storage.

The object recognition device may be a physical device such as a monitoring device having an object recognition function (the monitoring device is also referred to as a monitoring point such as a camera, or the like). Of course, the object recognition device may also be a virtual device, for example, the object device is a virtual device composed of a monitoring device and an object recognition server. The monitoring equipment is used for collecting images and sending the images to the object recognition server, and the object recognition server recognizes the object from the images.

Further, it should be noted that the above-mentioned objects may include people, vehicles, animals, etc., and the objects are only exemplary and not particularly limited.

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

And the server is used for storing the video segments collected by the object identification equipment, storing the hidden time segments set by the user, returning the video segments to be inquired by the user when the user inquires the video segments and the like.

The following describes the video recording inquiry method provided by the present application in detail from both the setting of the hidden time period and the inquiry of the video recording period.

1. Setting of hidden time periods

In the present application, the client provides multiple types of roles for the user, such as a first type of role and a second type of role. Wherein, the first type role (also called as a first type user) has the authority to set the hidden time period, and the second type role (also called as a second type user) does not have the authority to set the hidden time period. For example, the first type of role can be an administrator role. The second type of role can be an operator role. Of course, other roles are possible, and this is only an example and is not particularly limited.

The following describes an exemplary setting of the hidden time period provided by the present application, taking the first type role as an administrator and the second type role as an operator.

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

Specifically, after the user logs in the system, if the user logs in the client in the administrator status, the client displays an administrator page to the user. The administrator page is provided with an option for triggering the setting of the hidden time period, and the administrator can complete the setting of the hidden time period by triggering the option.

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

In an alternative implementation manner, when the object recognition device detects that a specified object appears in the monitored area, the object recognition device may send a prompt message to the client. After receiving the prompt message displayed by the client, the administrator can set a hidden time period according to the video collected by the object identification device.

When the method is realized, the information of the specified object is pre-configured on the object recognition equipment, the information of the target object appearing at the monitoring point is collected at the object recognition equipment, whether the recorded information of the specified object is hit or not can be detected, and if the recorded information of the specified object is hit, the target object is determined to be the specified object.

It should be noted that, 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 a person appearing at the monitoring point.

When the object is a vehicle, the information of the designated object is the license plate number and the color of the designated 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 the embodiment of the application, after the object identification device determines that the target object is the designated object, the object identification device may send prompt information to the client. After receiving the prompt message, the administrator of the client may set a hidden time period based on the video returned by the object identification device (e.g., according to the time length of the target object appearing at the monitoring point).

The monitoring area is, for example, a conference room. The designated object is a company manager. And when the object identification equipment of the conference room detects that the manager enters the conference room, sending a reminding message to the client. The administrator may set the conference time length of the manager's meeting as the hidden time period, or set the time length occupied by important conference content in the conference as the hidden time period.

The administrator sets a corresponding relationship 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 identifier, and sends the hidden video setting request to the server.

After receiving the hidden video setting request, the server may record the corresponding relationship between the hidden time period and the monitoring point identifier.

In another alternative implementation manner, when the object recognition device detects that the specified object appears at the monitoring point, the object recognition device may send a prompt message to the client. The prompt message includes: the monitoring point identifies and specifies information of the object. The client may set the hiding period based on the information of the specified object returned by the object recognition device.

For example, the client may determine the stay 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 stay time.

For another example, the object recognition device further has a voice recognition function, and the object recognition device sends 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.

Here, the client automatically sets the hidden period is merely exemplified and 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: and hiding the corresponding relation between the time period and the monitoring point identification.

2. Video segment query

Referring to fig. 2, fig. 2 is a flowchart illustrating a video recording 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 the query request; the query request includes at least: a user identity;

the query request may further include: the identification of the target monitoring point to be inquired, the inquiry time period of the target to be inquired and the like. Here, the query request is merely exemplary and is not specifically limited.

When the user wants to inquire the video segment, the user can input the target monitoring point mark to be inquired, the target inquiry time segment to be inquired and other information on the client

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

The client side can generate a query request based on a target monitoring point identifier, a target query time period and a user identity identifier which are input by a 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.

When implemented, the query request may further include: and identifying a target monitoring point to be queried and querying a time period.

During query, the server stores the video segments collected by each monitoring point and the video time corresponding to each video segment. The recording time is a time period formed by the start time and the end time of a recording segment.

The server can search at least one video segment of the video time in the target query time period and corresponding to the target monitoring point identifier in the collected video segments.

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

The query request may also carry an identifier of a target monitoring point to be queried.

When the server determines 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 correspondence 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 server returns the video segments which are not matched with the hidden time periods and the video segments which are matched with the hidden time periods and provided with the hidden marks in the at least one video segment to an inquiry end for sending the inquiry request, so that the inquiry end respectively displays the video segments which are not matched with the hidden time periods and the video segments which are matched with the hidden time periods and provided with the hidden marks.

Step 203 is explained in detail below through step 2031 to step 2032.

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

Step 2031 is described in detail below by steps a1 through a 2.

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

Here, it may be that at least one target video segment matching the partial hiding period is determined, for example, in the case that in at least one hiding period, a video segment corresponding to the partial hiding period cannot be returned to the query side for display, only a target video segment matching another partial hiding period except the partial hiding period needs to be determined; or determining all target video segments according to each hidden time period, wherein all the target video segments include the target video segment which is determined for each hidden time period and is matched with the hidden time period.

When the method is realized, for the found video segments with intersection with the hidden time period, the target video segments matched with the hidden time period are determined from the video segments according to the hidden time period.

The found video segment having an intersection with the hidden time segment includes two cases.

In the first case, there is an intersection between the recording time of the recording segment and the hidden time segment, and the recording time of the recording segment is included in the hidden time segment. For this case, the server may directly use the recorded segment as a target recorded segment matching the hidden segment.

In the second case, there is an intersection between the recording time of the recording segment and the hidden time segment, and the recording time of the recording segment is not included in the hidden time segment. In this case, the server may divide the video segment based on the start time or the end time of the hidden time period to obtain a plurality of video segments, and use the divided video segments in the hidden time period as the 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 2020-06-0108: 00:00 to 2020-06-0112: 00: 00.

Suppose that the hidden time period corresponding to the monitoring point 1 is 2020-06-0109: 20:00 to 2020-06-0110: 20: 00.

After receiving the query request, the server may search at least one video segment, in the collected video segments, whose video recording time is within the target query time period (i.e., 2020-06-0108: 00:00 to 2020-06-0112: 00:00) and which corresponds to the target monitoring point identifier (i.e., monitoring point 1), where the searched video segment is shown in table 1.

Video segment	Starting 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 record segments that intersect the hidden segments, in this example, segments 2 and 3.

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

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

The divided fragments are shown in table 2.

Video segment	Starting time	End time
			Video segment 1	2020-06-01T08:00:00.000Z	2020-06-01T09:10:00.000Z
Segment 21	2020-06-01T09:10:00.000Z	2020-06-01T09:20:00.000Z
			Segment 22	2020-06-01T09:20:00.000Z	2020-06-01T10:10:00.000Z
Segment 31	2020-06-01T10:10:00.000Z	2020-06-01T10:20:00.000Z
			Segment 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 optional implementation manner, the target video segments to be returned are all target video segments matched with the hidden time period, and the server may set hidden marks for all target video segments matched with the hidden time period. Optionally, if the server determines all target video segments in the found at least one video segment according to each hidden time period, where all the target video segments include a target video segment determined for each hidden time period and matching with the hidden time period, the target video segment to be returned may be all the target video segments, and the server may set hidden marks for all the target video segments.

The hidden mark is used for enabling an inquiring party to distinguish the hidden video segment and the common video segment in the video segments returned by the server, so that the inquiring party can distinguish and display the hidden video segment and the common video segment.

Still taking the example of table 1 as an example, in this implementation, the server may determine that segment 22 and segment 31 are to-be-returned segments and set a hidden flag for segment 22 and segment 31.

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

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

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

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

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

condition 4: and 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 identification.

For condition 1:

the server can set different video recording levels for the collected video recording sections according to factors such as the importance of the video recording sections, and the lower the video recording level is, the lower the importance degree of the video recording is. Regardless of the identity of the inquiring party, as long as the inquiring party allows the hidden videos to be viewed, the server can return the target video segments with the video level lower than the preset threshold value to the inquiring party, and does not return the target video segments with the video level higher than the preset threshold value to the inquiring party. In other words, the service may return the video clips with low importance to the inquiring party and not return the video clips with high importance to the inquiring party.

For condition 2:

condition 2 is implemented such that the user can only view the hidden video segments of the video level that match the user level of the user (i.e., the video segments that match the hidden time period).

The server may set a video level for the collected video segments and a different user level for the user. In addition, the server pre-configures the video recording level of the target video recording segment which can be viewed by each user level.

For example, the video recording levels are respectively a level a, B level, and C level. The user level is configured to be a high-level administrator, a middle-level administrator and a common administrator.

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

TABLE 3

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

For condition 3:

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

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

If the hidden time period 2020-06-0109: 20:00 to 2020-06-0110: 20:00 is set by the inquiring party, both the determined section 22 and the section 31 are determined as the video sections to be returned.

And if the hidden time period 2020-06-0109: 20:00 to 2020-06-0110: 20:00 is not set by the inquiring party, determining that no video segment to be returned is matched with the hidden time period.

For condition 4:

the object to be achieved by condition 4 is: the high-level user can check the video clips matched with the hidden time periods set by the low-level user.

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

Assume that the above hidden time periods 2020-06-0109: 20:00 through 2020-06-0110: 20:00 are set by a middle-level administrator and the querying party is a high-level administrator.

The server may determine both the determined segment 22 and the segment 31 as video segments to be returned.

Further assume that the above hidden time periods 2020-06-0109: 20:00 through 2020-06-0110: 20:00 are set by a senior administrator and the querying party is a senior administrator.

Since the level of the inquiring party is lower than the level of the user who sets the hidden time period, the server can determine that there is no target video segment matching the hidden time period, which meets the inquiry authority of the inquiring party, so in this example, there is no video segment to be returned matching the hidden time period.

Step 2032: and if the user identity is determined to be used for indicating that the hidden video is allowed to be viewed according to the user identity, 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 provided with the hidden marks in the at least one video segment to an inquiry end for sending the inquiry request, so that the inquiry end displays 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 provided with the hidden marks in a distinguishing manner.

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

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 the first type and the user identity meets a preset user condition;

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

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

When the user identity identification is realized, if the user identity identification meets a first condition and/or a second condition, the server determines that the user identity identification is used for indicating that the hidden video is prohibited to be viewed;

the first condition includes: the user type corresponding to the user identity is a 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 the preset user condition.

Wherein, the first type user has the authority to set the hiding time period, and the second type user does not have the authority to set the hiding time period. For example, the first type of user is an administrator and the second type of user is an operator. Here, the first type user and the second type user are only exemplified and not particularly limited.

Various implementations of step 2032 and step 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 allow viewing of the hidden video.

In this case, when the server determines, according to the user identity, whether the user identity is used for indicating that the hidden video is prohibited from being viewed or permitted to be viewed, 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 for indicating that the hidden video is prohibited from being viewed. At this time, the server may delete all target video segments from the found video segments and return the target video segments to the query end for sending the query request, where all the target video segments include the target video segment determined for each hidden time segment and matched with the hidden time segment.

If the user type is the first type, determining that the user identity is used for indicating that hidden video viewing is allowed, and returning video segments which are not matched with all the 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.

Case 2: the present application divides the level of a first type of user (e.g., administrator), such as a high level administrator, a medium level administrator, a low level administrator, etc.

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

The second type of user (e.g., an operator) cannot view the hidden video.

In this case, the user conditions include: in at least one hiding time period, any hiding 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 whether the user id indicates that the hidden video record is prohibited or permitted to be viewed according to the user id are described below, which are only exemplary and are not specifically limited.

The implementation mode is as follows:

the server may determine a 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 for the user corresponding to the user identity. If any hidden time period (any hidden time period or any plurality of hidden time periods) is set for the user corresponding to the user identity in each hidden time period, determining that the user identity is used for indicating that the hidden video is allowed to be viewed, and returning video segments which are not matched with the hidden time periods and video segments which are matched with at least one hidden time period and are set with the hidden marks to the query end. And if all the hidden time periods are not the user setting corresponding to the user identity, determining that the user identity is used for indicating that the hidden video is forbidden to be viewed.

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

Assume that the query time period carried in the query request is 8:00-15: 00.

Assume that administrator 1 sets the hidden period 9:00-10:00 and administrator 2 sets the hidden period 13:00-14: 00.

Assume that the inquirer is administrator 1. Since administrator 1 sets the hidden period of the hidden period 9:00 to 10:00, administrator 1 allows viewing of the hidden video.

In addition, in combination with the above-mentioned manner that "the hidden time period corresponding to the video clip to be returned is set by the user indicated by the user identification", since the administrator 1 sets the hidden time period 9:00 to 10:00, the server may set the hidden flag for the video clip of 9:00 to 10:00, and the server may return the hidden flag set for 9:00 to 10: the video clip of 00, and the video clips of 8:00-9:00, 10:00-13:00 and 14:00-15:00 which are not matched with all the hidden time periods are returned.

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

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

The implementation mode two is as follows:

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

1) If the user type is the first type, the server can detect whether the user level of the user set in each hidden time period is lower than or equal to the user level corresponding to the user identity. And if the user level of the user with the any hidden time period is lower than the user level corresponding to the user identity, 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 are provided with the hidden marks to the inquiry end. And if the user levels of the users in all the hidden time periods are higher than the user levels corresponding to the user identity identifiers, determining that the user identity identifiers are used for indicating that the hidden video is forbidden to be viewed, deleting all target video segments from the searched video segments by the server and returning the target video segments to the query end for sending the query request, wherein all the target video segments comprise the target video segments which are determined for each hidden time period and are matched with the hidden time period.

Assume that the query time period carried in the query request is 8:00-15: 00.

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

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

In addition, in combination with the fact that the user level of the user for 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 identity identifier in the mode of determining the video clip to be returned, since the level of the administrator 3 is higher than the level of the administrator 2 for setting the hidden time period 13:00-14:00, the server can set the hidden mark on the video clip of 9:00-10:00, the server can return the video clip of 13:00-14:00 with the hidden mark to the device of the administrator 1, and return the video clip of 8:00-9:00, the video clip of 10:00-13:00 and the video clip of 14:00-15:00 which are not matched with the hidden time periods.

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

The implementation mode is three:

the server may determine a 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 identification, and detects whether the user level of the user set in each hidden time period is lower than the user level corresponding to the user identity identification.

And if any hidden time period is set for the user corresponding to the user identity and/or the user level of the user in the any hidden time period is set to be lower than the user level corresponding to the user identity, determining that the user identity is used for indicating that the hidden video is allowed to be viewed.

And if all the hidden time periods are not set for the users corresponding to the user identity identifiers and the user levels of the users in all the hidden time periods are set to be higher than the user levels corresponding to the user identity identifiers, determining that the user identity identifiers are used for indicating that the hidden videos are forbidden to be viewed.

Assume that the query time period carried in the query request is 8:00-15: 00.

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

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

In addition, in combination with the fact that "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 identifier and the hidden time period corresponding to the video clip to be returned is set by the user indicated by the user identifier" in the above manner of determining the video clip to be returned, since the administrator 1 sets the hidden time period 9:00 to 10:00 and the administrator 1 is higher than the administrator 2 setting the hidden time period 13:00 to 14:00, the server can put back the video clip of 13:00 to 14:00 setting the hidden mark, the video clip of 9:00 to 10 setting the hidden mark to the device of the administrator 1: the video recording segment of 00, and the video recording segments of 8:00-9:00, 10:00-13:00 and 14:00-15:00 which are not matched with all the hidden time segments.

2) And if the user type is the second type, determining that the user identity is used for indicating that the hidden video is prohibited to be viewed.

Therefore, the inquiring party can inquire the hidden video segment which is set by the inquiring party and corresponds to the hidden time segment which is set by the administrator and has lower level than the inquiring party. 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 divides the level of the second type of user (i.e., operator), such as a high level operator, a medium level operator, a low level operator, etc. The second type of users with the level higher than the preset user level threshold can view the hidden segment, and the second type of users with the level lower than the preset user level threshold cannot view the hidden segment.

The first type of user allows viewing the hidden video, or the first type of user allows viewing the hidden video when a preset user condition is met. "as shown in cases 1 and 2 above, and will not be described in detail here.

The following introduces that "a second type of user with a level higher than a preset user level threshold cannot view a hidden segment" and a second type of user with a level lower than the preset user level threshold cannot view the hidden segment ". "is used in the implementation of the method.

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 value, the server determines that the user identity is used for indicating that the hidden video is prohibited from being viewed.

And if the user type is a second type and the user level is higher than or equal to a user level threshold value, determining that the user identity is used for indicating that the hidden video is allowed to be viewed.

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

In addition, in the embodiment of the present application, after the querying party receives the video segments that do not match with each hidden time period and the video segments that match with at least one hidden time period and are provided with the hidden marks, the querying party can distinguish and display the video segments that do not match with each hidden time period and the video segments that match with at least one hidden time period and are provided with the hidden marks.

For example, as shown in fig. 3, the query end may display the video clips that do not match with each hidden time period and the video clips that match with at least one hidden time period and are provided with the hidden marks in a manner of distinguishing by the color of the video progress bar. For example, the progress bar corresponding to the video segment that matches at least one hidden time period and is set with the hidden mark is light gray. The progress bar corresponding to the video clip with unmatched hidden time periods is dark gray and the like.

Of course, in practical applications, the two different video clips may be displayed in a manner that the prompt characters appear on the video picture. For example, when a video segment is displayed in which all hidden time periods are not matched, the video playing window simultaneously displays a character of 'common video', and when a video segment is displayed in which at least one hidden time period is matched and a hidden mark is set, the video playing window simultaneously displays a character of 'hidden video'. Here, the manner of the differentiated display is merely exemplified and is not particularly limited.

In addition, in the embodiment of the present application, if the query end only receives the video segments that do not match with each hidden time period, but does not receive the video segments that match with at least one hidden time period and are provided with the hidden marks, the video segments that do not match with each hidden time period are displayed, and the content of the video segments that match with at least one hidden time period and are provided with the hidden marks is not displayed.

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

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