Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the portions relevant to the application are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

It is understood that the plurality of clients participating in location sharing in the embodiments of the present application may be applications running on a hardware device with data processing capabilities, such as a mobile terminal or a computer. The small program loaded on other application programs with instant messaging functions, such as the small program loaded on the WeChat, can also be used.

It will also be appreciated that the mobile terminal running the applet may be a mobile terminal having a positioning function, such as a terminal having a bluetooth positioning function. For example, the beacon may be a dedicated beacon or a mobile phone terminal supporting the iBeacon protocol.

Correspondingly, in the embodiment of the present application, a bluetooth base station and a server may be configured. Multiple databases may be configured in the server. The system comprises a map information database, a position information database, a safety level database and the like. The Bluetooth base station is used for receiving the geographic position information of the client side acquired and sent by the Bluetooth positioning terminal and sending the geographic position information to the server. The map information database configured in the server can be used for storing map information data, and can be a grid map or a vector map. The map data of multiple map layers such as basic map information, path information, connection information between building floors, user interest points and the like can be included. The location information database may be configured to store the received geographic location information of the client, may include high-precision positioning information of the client, such as a room, a floor, or a building where the client is located, and may further include real-time data, historical data, static data, and the like in a time dimension. The historical data may be information such as an activity track and a range of the client within a certain time difference, for example, 0.5 h. The security level database can be used for storing data such as the current security level corresponding to each client and the security level policy set in the server. The security level indicates the accuracy range of the client sharing the position information of the client in the position sharing process.

The server in the embodiment of the application can be used for receiving the geographic position information sent by the Bluetooth base station, checking and calling data in the database, after the current security level is determined, carrying out fuzzy processing on the geographic position information of the client participating in position sharing, and finally sending the geographic position information to other clients so as to realize the setting of the security level of the client uniformly and automatically in the position sharing process and realize the privacy protection of the client.

An application scenario of the embodiment of the present application, for example, an organization or an enterprise needs to invite other partners or clients to visit the plant equipment or participate in a meeting. The inviting party may configure a location sharing system, such as an applet, in the server. The generated applet can be sent to the participants through broadcasting and the like, for example, in a two-dimensional code mode, so that the client of the invited participant runs the applet by identifying the two-dimensional code to become the client capable of participating in location sharing. Such as running the applet using a WeChat or the like.

In this scenario, assume that the client of the inviter is the first client and the client of the invitee is the second client. The user initiating the invitation may preset a security level policy table in a security level database of the server, so that in the location sharing process, the server may determine current target security levels of the first client and the second client participating in the location sharing according to the preset security level policy table; or the inviter sends a security level customization message to the server through the first client, so that the server directly sets the security levels of the first client and the second client participating in the location sharing according to the security level customization message. The server may also prompt the second client to accept and sign the electronic agreement of the security level and time period of itself and the first client when sharing the location, wherein the second client may accept or may reject and require additional negotiation. When the position is shared, the position information of the client and all the second clients can be displayed on the first client according to the set safety level, the position information of the client and the first client can be displayed on the second client, and auxiliary functions of schedule reminding, second client track inquiry, conference sign-in and the like are provided.

It will be appreciated that the inviter may set the scope of application of the security level policy in the server so that different clients have different security levels. For example, the inviting party may set the security level policies of some or all of the clients participating in the location sharing in the security level database of the server. Or when the inviter sends the security level customization message to the server through the first client, the security level customization message carries part or all of the security levels of the clients participating in the location sharing.

Through the selective setting, only the security level of the first client can be set in the server, and the data security of the server is ensured. And for other invitees second clients participating in the position sharing, the second clients have a fixed security level which is default by the server so as to report the accurate position to the first client in real time. Or when the security level is set by using the security level customization message, the user negotiates with other second client users to determine the security level or the preliminary security level of each second client, so as to protect the information security of the second client.

The second client may view and sign the electronic agreement of the security level and time period of the shared location information upon receiving the access invitation, i.e., when the applet that runs the location sharing for the first time becomes the second client. And when the position is shared, displaying the position information of the first client and the first client according to the set security level, and providing auxiliary functions of navigation, conference sign-in and the like.

It will be appreciated that in this scenario, an administrator client may also be provided, which may be used to set or modify the security level policy table in the security level database, and may also be used to view current and historical location information of the second client of the invitees, such as current visitor location distribution, historical track of specified visitors, visitor location out-of-bounds records, and so on.

In another scenario, including multiple first clients and multiple second clients, where mutual location sharing is required, security levels may be negotiated together, and the security level setting of each client is completed in the server by any party. For example, the security level of all or part of the participation in location sharing may be set in the server by some first client or its user.

For convenience of understanding and explanation, in the location sharing process in the embodiment of the present application, protection of location information of the client initiating the invitation and the client corresponding to the invited party is performed, and the location sharing method and apparatus provided in the embodiment of the present application are described in detail below with reference to fig. 1 to 8.

Fig. 1 is a schematic flowchart illustrating a location sharing method according to an embodiment of the present application, where as shown in fig. 1, the method includes:

s110, position information of the first client and the second client is obtained and stored.

Specifically, the server may obtain current location information of a plurality of clients participating in location sharing. The location information may include spatial information, temporal information, and/or velocity information.

For example, a plurality of clients participating in location sharing operate on a bluetooth positioning terminal, the bluetooth positioning terminal may be a dedicated beacon or a mobile phone terminal supporting the iBeacon protocol, and the server may receive location information reported by each bluetooth positioning terminal.

After the server receives the position information of the first client and the second client, the server can use the map information database inside the server to match with the map information in the map information database, and then the current positions of the first client and the second client are obtained through calculation. Further, the calculated user location may be stored, such as in a location information database stored in a server.

For example, in the application scenario described above, the first client is an initiator and the one or more second clients are invitees. After the sharing position starts, the server may obtain and store position information reported by the first client and the second client, where the position information indicates a current spatial position, a current time, and a current speed of the first client and the second client.

And S120, determining a target security level of the first client and/or the second client based on a preset security level policy table or a received security level customization message.

Specifically, after the server obtains and stores the current space, time, speed, and other information of each client, the current target security level of each client may be determined according to a preset security level policy table or a received security level customization message. The target security level is used to indicate the accuracy range of the location information shared to the other party during the location sharing process.

Optionally, in the above application scenario, the inviter user may set a security level policy table in advance in the server, where the security level policy table may include a correspondence between the security level and the determination factor. The security level may include a plurality of levels ranging from obfuscation to precision, and a plurality of security levels may be set for spatial dimensions, temporal dimensions, and/or velocity dimensions of different precision. As shown in table 1 below, L4 is the highest precision level, which is accurate to the time precision and the space precision of the current time and meter level, and the precision is sequentially reduced, namely L3, L2, L1 and L0. Correspondingly, the safety factor is gradually improved from L4, L3, L2, L1 and L0.

TABLE 1 safety level Table

The above-mentioned determination factors may include distance, time, and location. That is, the security level policy table may include a distance security level comparison table, a time difference security level comparison table, and/or a location security level comparison table. Can be as shown in tables 2-4 below:

TABLE 2 distance safety class LUT

Distance (distance between sharers)	Safety level (time dimension/space dimension)
		>1000m	L1
500m-1000m	L2
		100m-500m	L3
<100m	L4

TABLE 3 time difference safety class LUT

Time (difference from preset time)	Safety level (time dimension/space dimension)
		>2h	L0
1h-1.5h	L1
		0.5h-1h	L2
10min-30min	L3
		0-10min	L4

TABLE 4 position safety level comparison table

Location (spatial location of invited party)	Safety level (time dimension/space dimension)
		Parking lot	L1
Hall	L2
		Office area	L3
Alert zone	L4

In the above comparison table, the security level corresponding to each determination factor may be the temporal and spatial security levels in table 1.

It can be understood that one or more of the security level policy tables may be selectively set in the server, and the corresponding security levels may be determined to be more finely divided according to actual situations, which is not limited in this embodiment of the present application.

For example, different security level policy tables may be set in the server for different clients. If the time difference safety level comparison table is set for the first client, the distance level safety comparison table is set for other second clients. Alternatively, a plurality of different security level policy tables may be set for the same client. If the time and distance safety level comparison table is set for the first client, and the priority of the time difference safety level comparison table is higher than that of the distance safety belt energy level comparison table before the preset moment. If the conference starts at two points in the afternoon, twelve am may be set as a preset time, so that before twelve am, the second client participating in the conference cannot obtain the accurate position of the first client in a certain way.

After the server obtains the location information of the plurality of clients participating in location sharing, the server may determine a target security level currently corresponding to each client according to the security level policy table.

Likewise, the determined target security level may be a target security level of the first client, i.e., the first client needs to protect its information security with respect to the second client. The target security level may also be a security level of the second client, that is, the second client also needs to protect its security information, and does not need the first client to master its real-time dynamic message.

For example, when the first client is an inviter and the second clients are invitees, and when only one lookup table, such as a distance security level lookup table, is stored in the server, the target security level may be determined by using the distance between the second client of the invitee and the first client. When the server is provided with the distance safety level comparison table and the time difference safety level comparison table which are arranged before twelve am and have higher priority, the target safety level is determined by checking the time difference safety level comparison table before twelve am. After twelve points, the first client's accurate location information may be viewed using the distance safety lookup table.

Optionally, the server may also customize the message by receiving a security level sent by a certain client. The security level customization message is utilized to determine a security level currently corresponding to each client. The security level customization message may include its own target security level or may include the current target security levels of all clients.

For example, in the above embodiment, when an organization needs to hold a meeting, the first client of the inviter may send a security level customization message to the server. And the server customizes the message according to the security level sent by the first client and determines the security level of the second client and the first client of each participant. I.e., determining the security level of each client participating in the location sharing.

S130, based on the target security level and the position information of the first client and the second client, sending the target position information of the second client to the first client, and/or sending the target position information of the first client to the second client.

Specifically, after the target security level and the current location information of each client are determined, the target location information may be sent to each client participating in location sharing according to the target security level.

For example, for the application scenario described above, the second client and the current target security level of the second client are both determined by the security level customization message to be L4 in time and space.

As shown in fig. 6, for the second client, such as the elevator currently located at the first floor, the server may directly send the current location information of the second client as the target location information to the first client, and send the location information of the first client as the target location information to the second client. As may be displayed on the first client: the second client is located in the elevator No. 1 of the first floor of the No. 3 building, and the current speed is 3 m/s. For the first client, currently located in the office of floor 5, then: the first client is located in the office of building 3, building 5 301, and the current speed is 0 m/s.

For another example, according to the location security level comparison table shown in table 4, since the second client is located in the first floor lobby, the target security level of the second client and the target security level of the first client are determined to be L2. The server may perform fuzzy processing on the location information of the first client and the second client, and generate target location information of the first client and the second client, so that the target location information is displayed at the first client: the second client is located in floor 3, floor xxxx, the current speed is 0-10m/s, and the second client displays that: the first client is located on floor 3, floor 5 xxxx, and the current speed is 0-10 m/s.

It will be appreciated that the first client may also display its current location information, as well as the second client.

Or, the map can be called at the first client and the second client, and the map is displayed in the form of icons. And e.g. on the map, displaying a dark area for the position of floor 3 to indicate that the second client is in floor 3.

For the convenience of understanding and explaining the detailed process of location sharing by a plurality of clients, the determination of the target security level and the generation of the target information are explained below by fig. 2 to 5.

S210, receiving a security level customization message sent by the first client.

S220, pushing the safety level customization message to the second client.

And S230, receiving a confirmation message of the security level customization message sent by the second client.

S240, acquiring the position information of the first client and the second client.

And S250, determining a target security level of the first client and/or the second client based on the security level customization message.

S260, preprocessing the position information of the first client and/or the second client based on the target security level, and generating target position information of the first client and/or the second client.

And S270, sending the target position information of the second client to the first client, and sending the target position information of the first client to the second client.

In this embodiment, in the above application scenario, the first client is an inviter initiating location sharing, and the at least one second client is an invitee. The first client may first generate and send a security level customization message to the server. It is to be understood that the security level customization message includes at least a target security level of the first client and/or the second client.

The target security level may be for the first client and/or the second client. That is, the first client may customize the security level for itself, so that the second client of the invited party cannot obtain the accurate information of the first client in real time. The information security of the invited party can be considered, and the security level information is customized for the invited party, so that the first client cannot acquire the position information of the second client in real time.

After receiving the security level customization message sent by the first client, the server can push the security level customization message customized by the first client to the multiple clients of the invited party. The second client may return an acknowledgement message to the server in response to the security level customization message.

For example, when the user of the second client agrees with the security level specified in the security level customization message, an acknowledgement message may be fed back to the server, and if not, an offline negotiation may be performed with the user of the first client. After the unification is achieved, the first client side can modify the target security level in the customized message, so that the server pushes a new security level customized message to the second client side again, and at the moment, the second client side can feed back a confirmation message to the server.

It is understood that in another example, the server may directly perform S240 without pushing the security customized message to the second client, that is, obtain the location information of the first client and the second client.

Specifically, after the target security level is determined, the accurate location information may be directly sent to the client participating in location sharing according to the determined target security level and the acquired location information. Or, the position information may be subjected to fuzzy processing to generate target position information matched with the accuracy of the target security level, and the target position information is sent to the corresponding client.

It is understood that, when sending the security level customization message, the first client may complete the setting of the security level of the whole location sharing process once before the location sharing starts. Or, the security level customization message can be sent at any time in the location sharing process, so that the server realizes the real-time adjustment of the security level.

It is also understood that the first client may include one or more target security levels in the security level customization message. That is, different security levels may be set in the server for different clients. For example, a first target security level corresponding to the first client and a second target security level corresponding to the second client may be included. The first target security level and the second target security level may be the same security level, and may be different security levels, so that different clients have different security levels.

According to the position sharing method, the server receives the safety level customization message sent by the first client, and then the target safety level of the first client and/or the second client is determined according to the safety level customization message, so that the position message can be sent to other clients after being subjected to fuzzy processing according to the target safety level of the client participating in sharing, position sharing is completed, information protection of different clients is achieved, and operation complexity is reduced.

Fig. 3 is a schematic flow chart of a location sharing method according to another embodiment of the present application, as shown in the figure, the method may include:

s310, position information of the first client and the second client is obtained.

S320, determining the current distance between the first client and the second client according to the position information of the first client and the second client.

S330, determining the target security level of the first client and/or the second client according to the current distance and the distance security level comparison table.

S340, preprocessing the position information of the first client and/or the second client based on the target security level, and generating target position information of the first client and/or the second client.

And S350, sending the target position information of the second client to the first client, and/or sending the target position information of the first client to the second client.

Specifically, in the embodiment of the present application, when the security level policy table set in the server by the first client is a distance security level comparison table, in the location sharing process, after the server obtains the location information of the first client and the second client, the distance between the first client and the second client may be calculated, and then the distance security level comparison table is searched to determine the target security levels of the first client and the second client.

For example, when the distance between the first client and the second client is calculated to be 500m, the target security level in space and time of the first client and the second client may be determined to be L1 as shown in table 2.

It can be understood that a plurality of distance security level comparison tables may be preset in the server, for example, two distance security level comparison tables, one distance security level comparison table corresponding to the first client, and one distance security level comparison table corresponding to the second client may be set. The two distance security level comparison tables can have the same or different security level corresponding relations. Therefore, different target security levels of the first client and the second client can be determined after the distance between the first client and the second client is obtained.

After the target security level is determined, the accurate position information can be directly sent to the client participating in position sharing according to the determined target security level and the acquired position information. Or, the position information may be subjected to fuzzy processing to generate target position information matched with the accuracy of the target security level, and the target position information is sent to the corresponding client.

In the embodiment of the application, after the distance between the first client and the second client is obtained through calculation, the target security level of the first client and/or the second client can be determined by using a distance security level comparison table preset in the server, and then the position information of the second client and the position information of the second client can be sent to each other after fuzzy processing according to the determined target security level, so that position sharing is completed, flexible adjustment of the target security level is realized, operation complexity is reduced, and user experience is improved.

Fig. 4 is a schematic flow chart of a location sharing method according to another embodiment of the present application, where as shown in the figure, the method includes:

s410, acquiring the position information of the first client and the second client.

And S420, determining the current position of the second client based on the position information of the second client.

S430, determining the target security level of the first client and/or the second client based on the current position of the second client and the position security level comparison table.

S440, preprocessing the position information of the first client and/or the second client based on the target security level, and generating target position information of the first client and/or the second client.

S450, sending the target position information of the second client to the first client, and/or sending the target position information of the first client to the second client.

Specifically, in the embodiment of the present application, a location security level comparison table may be preset in the server, as shown in table 4. After the spatial location of the second client is obtained, the location security level comparison table can be checked to determine the current target security levels of the first client and the second client.

For example, when it is determined that the current location of the second client is in the parking lot, the current target security level is determined to be L0 according to the location security level comparison table.

After the target security level is determined, the accurate location information can be directly sent to the client participating in location sharing according to the determined target security level and the acquired location information. I.e., S440 is not performed. Or, the position information may be subjected to fuzzy processing to generate target position information matched with the accuracy of the target security level, and the target position information is sent to the corresponding client.

In the embodiment of the application, after the position information of the second client is acquired, the current target safety level is searched and determined through the preset position safety level comparison table, and then the position sharing can be completed according to the determined target safety level, so that the flexible adjustment of the safety level in the position sharing process is realized, the operation complexity is reduced, and the user experience is improved.

Fig. 5 is a schematic flow chart of a location sharing method according to another embodiment of the present application, where as shown in the figure, the method includes:

s510, position information of the first client and the second client is obtained.

And S520, determining the current time.

S530, determining a time difference based on the current time and a preset time.

And S540, determining the target security level of the first client and/or the second client according to the comparison table of the time difference, the time security and the like.

And S550, preprocessing the position information of the first client and/or the second client based on the target security level, and generating target position information of the first client and/or the second client.

And S560, sending the target position information of the second client to the first client, and/or sending the target position information of the first client to the second client.

Specifically, in the embodiment of the present application, in the location sharing process, when the security level policy table in the server is set as the time difference security level comparison table shown in table 3, the current target security level may be determined by determining the time difference between the current time and the preset time and checking the time difference security level comparison table.

For example, when the conference starts at two pm, the preset time is two pm. The target security level may be determined based on the time difference between the current time of day and two o' clock in the afternoon. Assuming that the current time is noon, the time difference is determined to be 3h, i.e., greater than 2h, and the target security level of the first client and/or the second client is determined to be L0.

After the target security level is determined, the position information may be subjected to fuzzy processing according to the determined target security level and the obtained position information, so as to generate target position information matching the accuracy of the target security level L0, and send the target position information to the corresponding client. And if the target position information of the first client is sent to the second client, the target position information of the second client is sent to the first client.

If the determined target security level is L4, it is possible to directly transmit accurate location information to the clients participating in location sharing without performing S540.

In the embodiment of the application, the target safety level is determined by calculating the time difference between the current time and the preset time, so that the safety level is flexibly adjusted in the position sharing process, the operation complexity is reduced, and the user experience is improved.
