All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Questionnaires generally represent the overall data by sample data and are an important survey method. The questionnaire survey has strong operability and a strict sampling method, so that the representativeness of the obtained sample data is stronger.
In the conventional questionnaire survey method, sample information input by a person to be surveyed is acquired through terminal equipment, the sample information is uploaded, and a server of a questionnaire survey system analyzes and processes the sample data to obtain a questionnaire survey result. However, the server may receive sample data collected from a non-target area, thereby causing inaccurate survey results of the determined questionnaire.
In order to solve the above problem, embodiments of the present application provide a data verification method and apparatus, where, compared with the prior art, sample data of a questionnaire uploaded by a terminal device in the present application includes location information, and it is determined that only sample data belonging to a target area is available through verification of the location information. Therefore, the sample data which does not belong to the target area is avoided, and the accuracy of the survey result of the questionnaire survey is improved.
The following describes a usage scenario of the present application.

After receiving the sample data of the questionnaire, the server 102 processes the sample data of the questionnaire to determine the survey result of the questionnaire. If the questionnaire is only for the target area, the terminal device 101 needs to collect sample data of the questionnaire in the target area. Similarly, when receiving sample data of a questionnaire, the server 102 needs to verify location information corresponding to the sample data to ensure that the sample data is available.
The terminal device 101 may be a mobile phone (mobile phone), a tablet (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in smart home (smart home), and the like. In the embodiment of the present application, the apparatus for implementing the function of the terminal may be a terminal device, or may be an apparatus capable of supporting the terminal to implement the function, for example, a chip system, and the apparatus may be installed in the terminal device. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices.
It should be noted that, the application scenarios related to the embodiment of the present application are not limited, and the data verification method provided in the embodiment of the present application may also be applied to any other scenarios that need to perform location verification.
It is to be understood that the data verification method may be implemented by the data verification apparatus provided in this embodiment of the application, and the data verification apparatus may be a part or all of a certain device, for example, a processor of the second server or the server.
The following takes a server integrated or installed with relevant execution codes as an example, and details the technical solution of the embodiment of the present application with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a schematic flow chart of a data verification method provided in an embodiment of the present application, and the embodiment of the method shown in fig. 2 relates to a specific process of how a server determines a survey result of a questionnaire survey. As shown in fig. 2, the data verification method includes:
s201, receiving sample data of the questionnaire survey sent by the terminal equipment, wherein the sample data contains position information which represents that the terminal equipment collects when a questionnaire survey is used by a surveyor to conduct an in-house survey on a user.
In the application, the investigator can use the questionnaire survey to conduct an in-house survey on the user, and after the user fills in the questionnaire survey, the investigator can upload sample data of the questionnaire survey filled in by the user to the server by using the terminal device.
It should be noted that sample data of a questionnaire in the present application includes location information acquired by a terminal device, where the location information may be acquired by using a third-party map application, or may be acquired by using an application of the questionnaire itself, and this is not limited in this embodiment of the present application.
In some embodiments, the location data of the terminal device includes a latitude and longitude at which the terminal device is located.
S202, determining the area to which the sample data belongs according to the sample data.
In this step, when the server receives sample data of the questionnaire transmitted by the terminal device, the area to which the sample data belongs may be determined according to the location information in the sample data.
The embodiment of the present application does not limit how to determine the region to which the sample data belongs according to the sample data. For example, if the sample data includes the longitude and latitude where the terminal device is located, the location of the terminal device on the map may be determined based on the longitude and latitude where the terminal device is located. Subsequently, based on the area of the questionnaire divided in advance, the area to which the sample data belongs is determined.
And S203, if the area to which the sample data belongs is in the target area of the questionnaire, determining that the sample data is available.
The target area of the questionnaire survey may be an area where a user of sample data to be collected by the questionnaire survey is located, for example, a certain office building, a certain residential area, a certain park, and the like.
In this step, after the server determines the area to which the sample data belongs according to the sample data, it may be determined whether the area to which the sample data belongs is within a target area of the questionnaire, and if so, it is determined that the sample data is available.
In other embodiments, if it is determined that the region to which the sample data belongs is not within the target region of the questionnaire, it may be determined that the sample data is not available, at which point the server may discard the unavailable sample data.
In the embodiment of the present application, how to determine whether the area to which the sample data belongs is in the target area of the questionnaire survey is not limited, and for example, the latitude and longitude range of the area to which the sample data belongs may be compared with the latitude and longitude range of the target area of the questionnaire survey. And if the longitude and latitude range of the area to which the sample data belongs is not within the longitude and latitude range of the target area, determining that the area to which the sample data belongs is not within the target area of the questionnaire.
In other optional embodiments, before determining that the sample data is available, it may be checked whether the sample data is tampered. For example, the sample data of the questionnaire also contains verification data, and the verification data is used for verifying whether the sample data is tampered. The verification data is generated by encrypting questionnaire information filled in by a user in the questionnaire survey when the questionnaire survey is stored. After receiving the sample data of the questionnaire survey sent by the terminal device, the server can decrypt the verification data by using the key to obtain the decrypted questionnaire information. And if the decrypted questionnaire information is consistent with the questionnaire information in the sample data, determining that the sample data is not tampered.
Wherein the questionnaire information comprises at least one of the following: the name of the person who fills out the questionnaire, the age of the person who fills out the questionnaire, the sex of the person who fills out the questionnaire, the certificate information of the person who fills out the questionnaire, and the position data of the terminal device.
And S204, determining the survey result of the questionnaire survey according to the available sample data.
In this step, when it is determined whether the sample data is available, the server may determine the survey result of the questionnaire based on the available sample data after completing the collection of all available sample data.
In the embodiment of the present application, how to determine the survey result of the questionnaire survey is not limited, and a common sample data processing method may be adopted, for example, statistics, comparison, and calculation of target questionnaire information in sample data.
According to the data verification method, sample data of the questionnaire survey sent by the terminal device is received, and the sample data contains position information collected by the terminal device when a representative investigator uses the questionnaire survey to carry out an in-house survey on a user; determining the region to which the sample data belongs according to the sample data; if the area to which the sample data belongs is in the target area of the questionnaire survey, determining that the sample data is available; according to available sample data, determining the survey result of the questionnaire survey. Compared with the prior art, the method and the device have the advantages that the sample data in the target area is screened out according to the position data of the terminal device when the sample data of the questionnaire survey is collected, so that the survey result of the questionnaire survey is determined by using the sample data in the target area, and the accuracy of the survey result of the questionnaire survey is improved.
On the basis of the above embodiment, a specific description is given below as to how the server checks sample data of a questionnaire survey. Fig. 3 is a schematic flow chart of another data verification method provided in the embodiment of the present application, and as shown in fig. 3, the data verification method includes:
s301, receiving sample data of the questionnaire survey sent by the terminal equipment, wherein the sample data contains position information which represents that the terminal equipment collects when a questionnaire survey is used by a surveyor to conduct an in-house survey on a user.
S302, determining the area to which the sample data belongs according to the sample data.
S303, determining whether the area to which the sample data belongs is in the target area of the questionnaire survey.
If yes, executing steps S304-S305, otherwise executing steps S306-S307
S304, determining that the sample data is available.
S305, determining the survey result of the questionnaire survey according to the available sample data.
S306, determining that the sample data is unavailable.
And S307, discarding the unavailable sample data.
On the basis of the above embodiment, after the available sample data is determined, the quota of the sample data of the questionnaire can be further regulated by using the available sample data. The following is a detailed description of how to govern the quota of sample data for a questionnaire. Fig. 4 is a signaling interaction diagram of a data verification method provided in an embodiment of the present application, and as shown in fig. 4, the data verification method includes:
s401, the terminal equipment sends sample data of the questionnaire survey to the server, wherein the sample data contains position information which represents that the terminal equipment collects when the questionnaire survey is used by a surveyor to conduct an entrance survey on a user.
S402, the server determines the area to which the sample data belongs according to the sample data.
And S403, if the area to which the sample data belongs is in the target area of the questionnaire, the server determines that the sample data is available.
The technical terms, technical effects, technical features, and alternative embodiments of S401 to S403 can be understood with reference to S201 to S203 shown in fig. 2, and repeated descriptions thereof will not be repeated here.
S404, the server acquires the accumulated quantity of sample data of the questionnaire survey.
The accumulated amount of sample data may be the total amount of available sample data already stored by the server.
In this step, after determining that the sample data is available, the server may update the cumulative number of sample data and then obtain the cumulative number of sample data for the questionnaire survey.
It should be understood that, in the embodiment of the present application, there is no limitation on the frequency of obtaining the accumulated quantity of sample data of the questionnaire by the server, and in an alternative implementation, the server may obtain the accumulated quantity of sample data at a preset time interval, where the preset time interval is five minutes, for example. In another optional implementation, the server obtains the cumulative number of sample data once after determining that the sample data is available and updating the cumulative number of sample data each time.
S405, the server adjusts quota of sample data of the questionnaire to be acquired in the target area according to the accumulated quantity of the sample data of the questionnaire.
In this step, after the server obtains the cumulative number of sample data of the questionnaire, the server may adjust the quota of the sample data of the questionnaire to be obtained in the target area according to the cumulative number of sample data of the questionnaire.
It should be understood that the quota of sample data for a questionnaire may be the number of sample data for the questionnaire that remains to be acquired for the target area.
The embodiment of the application does not limit how to adjust the quota of the sample data of the questionnaire to be acquired in the target area. For example, the total amount of sample data of a questionnaire to be acquired may be preset in the server, and the server may subtract the accumulated number of sample data of the questionnaire from the total amount of sample data of the questionnaire to be acquired to determine a quota of sample data of a current questionnaire.
S406, if the quota of the sample data of the questionnaire survey to be acquired in the target area is less than or equal to zero, the server sends first indication information to the terminal equipment, wherein the first indication information is used for indicating that the questionnaire survey is stopped to carry out the in-house survey on the user.
In this step, after the server adjusts the quota of the sample data of the questionnaire to be acquired in the target area, if the quota of the sample data of the questionnaire to be acquired in the target area is less than or equal to zero, it may be determined that the server has acquired enough sample data, and at this time, the server may send first indication information to the terminal device, and instruct the terminal device to stop using the questionnaire survey to perform user-entry survey on the user.
According to the data verification method and device provided by the embodiment of the application, after the server determines available sample data, the accumulated quantity of the sample data of the questionnaire survey can be acquired. And then, the server adjusts the quota of the sample data of the questionnaire to be acquired in the target area according to the accumulated quantity of the sample data of the questionnaire. If the quota of the sample data of the questionnaire survey to be acquired in the target area is less than or equal to zero, the server sends first indication information to the terminal equipment, wherein the first indication information is used for indicating that the questionnaire survey is stopped to carry out the in-house survey on the user. By the mode, the server can adjust the quota of the sample data of the questionnaire in real time based on the available sample data which is checked, and the questionnaire is indicated to be stopped when the quota of the sample data of the questionnaire is less than or equal to zero, so that the generation of extra workload is avoided.
On the basis of the above embodiments, in order to ensure that the user of the questionnaire survey is always within the target area, the server may further check initial location data where the terminal device is located when starting the questionnaire survey, and only if the initial location of the terminal device is within the target area, the server may authorize the investigator using the terminal device to start the user-in survey using the questionnaire survey. Fig. 5 is a signaling interaction diagram of another data verification method provided in an embodiment of the present application, and as shown in fig. 5, the data verification method includes:

In the present application, before the investigator starts to perform the in-house investigation on the user by using questionnaire investigation, the terminal device needs to be used to obtain authorization from the server.
For example, the questionnaire application may be opened by a questionnaire staff, an authorization button on an interface of the questionnaire application is clicked, and after detecting that the questionnaire clicks the authorization button, the terminal device may send an authorization request triggered by the questionnaire to the server to request the questionnaire staff to start an in-user survey on the user by using the questionnaire. The authorization request comprises initial position data of the terminal equipment when the authorization request is triggered.
And S502, if the initial position data of the terminal device is in the electronic fence corresponding to the target area of the questionnaire survey, the server sends second indication information to the terminal device, wherein the second indication information is used for indicating a surveyor to start an entrance survey for the user by using the questionnaire survey.
In the application, the server can set the electronic fence on a map in the server according to the target area of the questionnaire survey of the pre-device group. After the server receives the authorization request, the initial position data of the terminal equipment in the authorization request can be marked on the map, so that whether the initial position data are in the electronic fence corresponding to the target area of the questionnaire survey or not is judged. If yes, the server sends second indication information to the terminal device, and the investigator is instructed to use the questionnaire survey to start the user-in survey.
And S503, the terminal equipment sends sample data of the questionnaire survey to the server, wherein the sample data contains position information which represents that the terminal equipment collects when the questionnaire survey is used by a surveyor to conduct an entrance survey on the user.
S504, the server determines the area to which the sample data belongs according to the sample data.
And S505, if the area to which the sample data belongs is in the target area of the questionnaire, the server determines that the sample data is available.
S506, according to the available sample data, the server determines the survey result of the questionnaire survey.
The technical terms, technical effects, technical features and alternative embodiments of S503 to S506 can be understood by referring to S201 to S204 shown in fig. 2, and repeated descriptions thereof will not be repeated here.
