Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.

An embodiment of the present application provides a method for pushing service information, which is applied to a client, and specifically, as shown in fig. 1, the method includes:

101. user data of a user is acquired, and position information of the user is determined from the user data.

Wherein the location information is used for characterizing the current geographic location of the user.

Since there are a lot of different data in the user data, and not all of the data are meaningful for the service information push of this embodiment, in this embodiment, since it is a method for pushing service information, the location of the user is crucial in the service information push process, and therefore after the user data is acquired in this step, the location information that determines the current geographic location of the user is mainly acquired from the user data.

102. And processing the position information according to a preset algorithm to obtain a position identifier corresponding to the position information.

The preset algorithm is used for dividing the position information based on the position areas to obtain the position identification corresponding to each area.

Since the location information is information representing the current location of the user, in order to ensure that the location privacy of the user is not revealed, in this embodiment, the location information of the user may be processed by a preset algorithm to obtain a set of tags, i.e., location identifiers, which can represent the location of the user but do not reveal the actual geographic location of the user.

It should be noted that, in this embodiment, the preset algorithm may be any algorithm capable of processing the coordinates of the geographic location into a group of characters, and in addition, in the process of pushing the service information based on the location by the corresponding user, in many cases, it is not necessary to specifically identify the "point" where the user is located, but only to know an area where the user is located.

103. And sending the position identification to the server through the stealth query algorithm so that the server feeds back corresponding service information based on the position identification.

In practical applications, the covert tracking query algorithm has the characteristic that a data provider cannot know the data content specifically requested by a data requester in the process of data interaction, but can only know that the data provider performs a data query process once, so that in the embodiment, the characteristic of the covert tracking query algorithm can be used for data interaction between a client and a server. Therefore, the server can be further prevented from knowing which user makes a request for which data in the process of data feedback, and the safety of personal position privacy is improved.

The embodiment of the present application provides another method for pushing service information, which is applied to a server, and specifically as shown in fig. 2, the method includes:

201. a location identification is received from a client.

After the server receives the location identifier of the client, it can be known that the user actually needs to push the relevant service information based on the geographic location. Meanwhile, the meaning and form of the location identifier in this embodiment are the same as those in the embodiment of the client, and are not described herein again.

In addition, the manner of receiving the location identifier in this step may be performed according to actual selection of the user, and is not limited herein, and only the transmission manner in step 103 in the foregoing embodiment is ensured to be consistent.

202. And acquiring service information corresponding to the position identification from the local data of the server through an implicit track query algorithm, and feeding back the service information to the client.

Since the local data of the server contains a large amount of data content, after receiving the location identifier, the corresponding service information may be obtained based on the location identifier, and the service information may include service information in various aspects of a clothed and eating residence, which is not limited herein, and may be selected based on an application scenario of the server, for example, when the server is a cloud server of a taxi-taking software manufacturer, the service information may be vehicle information.

In addition, because the server may have a risk of data leakage when acquiring the service information corresponding to the location identifier, the service information corresponding to the location identifier may also be acquired by using the implicit track query algorithm in this step and fed back, so that it is ensured that the server side cannot know what the service information specifically requested by the current client is, nor which user knows, in the process of acquiring and feeding back the data by the server, thereby improving the security of the location privacy of the user.

The present embodiment provides a method for pushing service information, where user data of a user can be obtained at a client side, location information of the user is determined from the user data, the location information is processed according to a preset algorithm to obtain a location identifier corresponding to the location information, and finally the location identifier is sent to a server through an implicit query algorithm, so that the server can feed back corresponding service information based on the location identifier. Meanwhile, the server side can receive the position identification from the client side, acquire the service information corresponding to the position identification in the local data of the server through the track hiding query algorithm, and feed the service information back to the client side, so that the function of pushing the service information is completed based on the interaction between the client side and the server. Compared with the prior art, in the method, the position information is used for representing the current geographic position of the user, and the preset algorithm is used for dividing the position information based on the position areas to obtain the position identifier corresponding to each area, so that the condition that only the position identifier is uploaded by the user instead of the actual geographic position coordinate in the process of pushing the service information is ensured, that is, the user does not need to specifically upload the current position of the user, but replaces the actual coordinate in an identifier mode, the problem of position leakage possibly caused by uploading the geographic position coordinate by the user in the conventional process of pushing the service information is solved, and the risk of personal position privacy leakage of the user is reduced. In addition, because the hiding trace query algorithm is utilized in the process that the client sends the position identifier and the server queries the service information corresponding to the position identifier based on the position identifier and feeds back the service information, the hiding trace query algorithm has the characteristic that a data provider can be prevented from knowing the content of specific query data in the process of data request at two ends, and only one data query action is known, so that in the service information pushing process of the application, the situation that personal data is leaked is avoided, the situation that the personal position is leaked is further avoided, and the safety of personal privacy is integrally improved.

For the following description in more detail, an embodiment of the present application provides another access control method implemented by interaction between a client and a server, and as shown in fig. 3 in detail, the method includes:

301. the client acquires user data of the user and determines position information of the user from the user data.

In this embodiment, the descriptions of the user data, the location information, and the like are all the same as those in step 101 in the foregoing embodiment, and therefore, redundant description is not repeated in this embodiment.

302. And the client processes the position information according to a preset algorithm to obtain the position identification corresponding to the position information.

In practical application, the position information representing the geographical position of the user is mainly determined based on a Global Positioning System (GPS), that is, longitude and latitude, so in this embodiment, the position information includes longitude information and latitude information, and the preset algorithm for processing the position information into a position identifier may be a spatial index algorithm, that is, a GeoHash algorithm, which is a method of spatial indexing, and the basic principle is to understand the earth as a two-dimensional plane, and by encoding two-dimensional spatial longitude and latitude data into a character string, a plane can be recursively decomposed into smaller subblocks, each subblock having the same code in a certain longitude and latitude range. The encoding rule is as follows: firstly, dividing a latitude range (-90,90) into two sections (-90,0) and (0,90) in half, if a target latitude is positioned in the previous section, coding the target latitude into 0, otherwise coding the target latitude into 1, then averagely dividing the target latitude into two sections according to the section in which the target latitude falls, and repeating the steps until the precision meets the requirement, sequentially dividing the longitude (-180,180) by using the same algorithm, then combining the codes of the longitude and the latitude, placing the latitude at odd bits, placing the longitude at even bits, forming a new string of binary codes, and coding according to Base 32.

Based on this, the step may specifically be: and processing the longitude information and the latitude information through a spatial index algorithm to obtain the position identification.

The spatial index algorithm is an algorithm capable of converting longitude and latitude into a numerical value for output, and the numerical value is obtained after conversion, namely the position identifier is divided according to the area after converting the whole geographic area into a plane, so that the position can be represented, and meanwhile, the process of converting a plurality of point coordinates in one area into area coordinates is realized, the data volume of the position identifier is greatly reduced in magnitude, the data storage is facilitated, the data pressure of a server is reduced, meanwhile, the time consumption during data query is reduced, and the convenience of the pushing process of service information is integrally improved.

303. And the client judges whether the service information corresponding to the position identification exists in the local data of the client.

In some scenarios, sometimes a user does not necessarily need to obtain corresponding service information from the server, and for example, in a case that some service information is already cached in the client, after the location identifier is determined in the foregoing steps, it may also be directly determined whether the service information corresponding to the location identifier exists in the local data of the client.

Based on the determination result, when it is determined that there is, step 304 is performed, and otherwise, step 305 is performed.

304. And if the client judges that the service information corresponding to the position identification exists in the local data of the client, the client outputs the service information.

When the service information is determined to exist, it indicates that the user may have cached the service information of the location identifier locally at the client in the previous service information pushing process, and then the service information may be directly output to the user at this time, so that the user can know in time. Therefore, the process of obtaining the service information from the server is omitted, and the data security risk caused by uploading data when the service information is obtained is avoided.

305. The client sends the position identification to the server through the track hiding query algorithm, so that the server feeds back corresponding service information based on the position identification.

Based on the foregoing determination process, the step may specifically be:

and if the service information corresponding to the position identification does not exist in the local data, sending the position identification to a server through an implicit query algorithm so that the server can feed back the corresponding service information based on the position identification.

When the service information corresponding to the position identifier does not exist in the local data, the service information is not cached before or the pushing operation of the process service information is not executed before, and then the service information can be sent to the server through the position identifier by an implicit query algorithm. In addition, the implicit track query algorithm described in this embodiment is consistent with the description in the foregoing embodiments, and is not described herein again.

306. And the server adds a position identifier for each service information to form a service identifier group.

Each service identification group comprises one position identification and at least one piece of service information, and the position identification is obtained after the geographic position is processed based on a spatial index algorithm.

In order to avoid the disclosure of the personal location privacy when the user acquires the service information, in this embodiment, the server may perform a unified adding operation on the service information and the location identifier that need to be provided in advance to obtain a service identifier group formed by at least one piece of service information corresponding to each location identifier.

307. The server receives a location identification from the client.

In this embodiment, the manner in which the server receives the location identifier from the client may be performed by selecting any data interaction manner, which is not limited herein, as long as it is ensured that the manner is consistent with the manner in which the client sends the location identifier to the server in the foregoing step.

308. And the server acquires the user identifier corresponding to the position identifier through an implicit query algorithm based on the position identifier and acquires the historical position record corresponding to the user identifier.

Wherein the historical position record records at least one position identifier of the user corresponding to the user identifier in a preset time period.

Since the location of the user is not constant in practical applications, it is sometimes inconvenient to provide the service information to the user during the process of changing the location of the user, for example, when the user keeps changing the geographical location from a plurality of provinces and cities for a period of time, the behavior of the user is abnormal, and there is no need to provide the service information based on the location identification.

In view of this, in this embodiment, the user identifier corresponding to the location identifier may also be obtained based on the introspection query algorithm, that is, which user needs to push the service information currently is determined, and then the historical location record corresponding to this user identifier is obtained. The historical location record may be understood as a record of the location of the user over a period of time, and at least one location indicator over a preset period of time.

309. And the server determines the position change times of the corresponding user identification based on the position identification in the historical position record and the current position identification.

After the historical location record of the user is determined, since the historical location record includes a plurality of location identifiers recorded by the user before, it is also necessary to count the total location change of the user in the period of time, that is, count the number of location changes that occur together including the current location identifier and the location identifier in the historical location record. For example, when the historical location record includes location identifier a, location identifier B, and location identifier C, and current location identifier D, the method based on this step can determine that the number of times of location change is 3.

Based on the different location change times, when the preset times are exceeded, it may indicate that the location of the user is abnormal, and then it is obviously not applicable to provide the corresponding service information to the user, so when the preset times are determined to be exceeded, 310 may be executed, whereas when the preset times are determined not to be exceeded, 311 may be executed.

310. And when the position change times exceed the preset times, the server determines that the position of the user corresponding to the user identifier is abnormal, and prohibits the feedback of the service information based on the position identifier.

When the number of times of position change is determined to exceed the preset number, the position of the user is always changed, so that the behavior of the user may be abnormal, and at this time, it may be inappropriate to provide service information based on the position identifier.

For example, the method of this embodiment is applied in a scenario that when a financial institution pushes service information, since the number of times of location change of the user a is 15 and exceeds the preset number of times 3, which indicates that the user a always changes addresses, the user credit of the user a may be problematic, and at this time, it is not time-efficient to provide service information of a corresponding financial product, and therefore, it may be prohibited to provide corresponding service information based on the location identifier.

311. And the server acquires the service information corresponding to the position identifier from the local data of the server through the track hiding query algorithm and feeds the service information back to the client.

When the position change times of the user is determined not to exceed the preset times, the positioning of the user is normal, and the condition that the user behavior is abnormal does not exist, so that the client sends the position mark to indicate that the user really needs the service information, and therefore the corresponding service information can be obtained from the local data of the server based on the introspection query algorithm and fed back.

Specifically, based on the foregoing steps, since the service information and the location identifier in the server local data have been processed to obtain the service identifier group, this step may be:

and determining the service identifier group corresponding to the position identifier in the local data of the server through an introspection query algorithm, and acquiring the service information in the service identifier group.

Therefore, based on the service identifier group, at least one piece of service information corresponding to the corresponding location identifier can be directly acquired, that is, when the service information is multiple and contains different services for different scenes, the multiple pieces of service information can be directly fed back to the client, so that the user can acquire the service information of multiple current locations at one time, and the user can comprehensively acquire all service recommendations of the current location.

For example, when the service indication group includes vehicle information for taxi taking, restaurant information for diet, and hotel information for accommodation, when the location identifier is received, the vehicle information, the restaurant information, and the hotel information may be directly fed back to the client, so that the user knows all recommended services for taxi taking, diet, and accommodation based on the client at the current location.

Further, in some cases, the service information that the user wants to obtain may be information of a commonly used location or place thereof, and in some cases, when there is an abnormality in the positioning system of the client, a situation of a positioning location error, that is, a situation of a detached commonly used area, is very easy to occur, so after the foregoing step 308, the method further performs further confirmation based on whether the current location identifier and the commonly used area are matched, which may specifically be as follows:

312. the server determines a common location for the corresponding user identification based on the historical location record.

Since the historical location records are information of the user at different locations, after statistics is performed on the information, the location where the user frequently goes, that is, the frequently-used location corresponding to the user identifier, can be determined.

313. The server judges whether the position identification is consistent with the common position.

After the frequent location is determined, because the user may have a location abnormal condition, that is, when the user location has an abnormal condition, a condition that the current location identifier does not match the actual frequent location may occur, which indicates that there may be a problem in the user location.

314. And if the server judges that the position identification is inconsistent with the common position, the server feeds back position confirmation information to the client so that the user can confirm whether the service information needs to be pushed based on the current position or not based on the position confirmation information.

When it is determined that the current location identity does not correspond to the frequent location, it may be the case that the user's location is in question, but it may also be the frequent location from which the user leaves, determining another location, such as a business trip. Then, in order to ensure the accuracy of service information push, it is necessary to confirm the user again, that is, feed back location confirmation information to the user end, where the location confirmation information can prompt the user about the current location and enable the user to determine whether the service information push needs to be performed based on the current location.

In order to achieve the above object, according to another aspect of the present application, an embodiment of the present application further provides a storage medium, where the storage medium includes a stored program, and when the program runs, a device in which the storage medium is located is controlled to execute the above service information push method.

In order to achieve the above object, according to another aspect of the present application, an embodiment of the present application further provides a device for pushing service information, where the device includes a storage medium; and one or more processors, the storage medium coupled with the processors, the processors configured to execute program instructions stored in the storage medium; and when the program instruction runs, executing the service information pushing method.

Further, as an implementation of the method shown in fig. 1 and fig. 3, another embodiment of the present application further provides a device for pushing service information applied to a client. The embodiment of the apparatus for pushing service information corresponds to the client in the foregoing method embodiment, and for convenience of reading, details in the foregoing method embodiment are not repeated again in this embodiment of the apparatus for pushing service information, but it should be clear that the apparatus in this embodiment can correspondingly implement all contents of the client in the foregoing method embodiment.

In addition, because the hidden trace query algorithm is utilized in the process of sending the position identifier by the client and the process of querying and feeding back the service information corresponding to the position identifier by the server based on the position identifier, the hidden trace query algorithm has the characteristic that a provider of data can be prevented from knowing the content of specific query data in the process of carrying out data requests at two ends, and only one data query action is known, so that in the service information pushing process of the application, the condition that personal data are leaked is avoided, the condition that the specific user requesting the service information at present is known at one side of the server, and the specific request is known at which service information is also unknown, the leakage of the personal position condition is avoided, and the safety of personal privacy is improved on the whole.
