Description

SYSTEM FOR PREVENTING DUPLICATE SURVEY AND METHOD THEREOF

The present disclosure relates to a system for preventing duplicated surveys and a method therefor.

A survey of members of the university is a representative way to understand the needs of students most clearly and to improve the quality of services. However, these surveys are operated one-time by department or business unit using tools such as Naver Form or are operated by system, so integrated management of data is not possible. and the problem of having to rely on expert groups for analysis.

In the present disclosure, in order to solve this problem, a survey can be conducted through various methods such as mail and SMS, and a system for integrated management of the survey used in the school is built, and based on this, integrated management and analysis are possible. We propose a standardized university-customized integrated survey system that can be provided by

In relation to the integrated management and survey analysis method of the standardized university survey system, research on authority management, survey question management method, and data analysis method that enables various access to various users is continuing.

For example, portal sites provide a variety of services that allow you to conduct surveys for free. Naver Form, Google Form, and SurveyMonkey are representative sites. Each service provides its own design and convenient interface, and even provides simple statistical results. In this paper, we design a service suitable for the university by examining the advantages of the service provided by each site.

The members of the university have very diverse positions, and their work is subdivided. The members are divided into professors, staff, graduate students, and undergraduate students, and professors have various positions such as assistant professor, associate professor, full professor, emeritus professor, research professor, and industry-university cooperation professor. Tasks according to the survey should be managed differently for each position. To this end, in order to manage survey access rights based on personal attributes such as job title and survey management, an access control method by identity and task is used.

The survey questions are operated by various departments with various survey questions. In order to integrate this, it is necessary to proceed with the integration and classification of the survey questions. To this end, various existing survey types are classified by CASE and managed systematically.

The survey results accumulated by CASE should be capable of time series analysis and correlation and logistic regression analysis. To this end, an analysis module can be developed with reference to R so that the data to be analyzed can be selected, an analysis method can be selected, and the analysis results can be output in graph and table form.

Also, mobile surveys may have reliability issues. For example, in the survey using the standardized form as described above, the generated URL is one and it becomes an environment in which anyone can respond to the survey through the URL. In this case, duplicate submission or one person responds with more than two votes This is because an imaginary number may occur in the response result.

Therefore, there is a need to implement a system for preventing duplicate responses by one person.

2 is a flowchart illustrating an operation of a server or a terminal according to an embodiment of the present disclosure.

The server 210 may perform step 221 of generating a questionnaire and a questionnaire identifier based on the database. A survey list may be stored in the database. A surveyor may input a topic related to a survey to the server 210 by wire or wireless. Based on the topic selected by the surveyor, the server 210 may automatically generate a survey.

The identifier of the questionnaire may include at least one of the order of the questionnaire, the subject of the questionnaire, the creation date of the questionnaire, or a unique number of the questionnaire. The identifier of the questionnaire may be a unique value for identifying the questionnaire.

The identifier of the questionnaire may have an expiration date. That is, a start time and an expiration time of the questionnaire identifier may be determined. The server 210 may perform the survey from a start time to an expiration time.

The server 210 may perform step 222 of obtaining information on the respondent of the questionnaire. The server 210 may directly receive information about the respondent from the surveyor. In addition, the server 210 may determine a part selected by the surveyor as the responder among the information on the plurality of respondents stored in advance.

The server 210 may store the previously stored information on the responder by the following process. The server 210 may receive information about the respondent of the survey from the surveyor in advance by wire or wireless. The information on the respondent may include personal information of the respondent or information about the responder terminal. The respondent's personal information may include at least one of a resident registration number, student number, age, address, phone number, e-mail address, current location, gender, major, account ID, and occupation of the respondent. Also, the information on the responder may include information on the responder terminal used by the responder. The information on the responder terminal may include at least one of a MAC address, a device serial number, a phone number, a device type, and an IP address of the responder terminal.

The server 210 may receive encrypted information about the responder. Also, the server 210 may encrypt and store information about the responder. Therefore, the server 210 only stores the encrypted information on the responder, and may not check the actual information on the responder.

For step 222 , the server 210 may obtain information about the responder from information previously stored in the memory through the process as described above. The server 210 may receive a limiting condition for a candidate responder from the surveyor. The server 210 may select a responder that satisfies a limited condition from among the personal information stored in the database. For example, when the questioner sets the limiting condition to "a student who has taken a specific subject", the server 210 may search for "a student who has taken a specific subject" in the memory to obtain information about the respondent.

Also, the information on the responder may include an identifier of the responder. The identifier of the responder may be a unique value for identifying the responder.

The server 210 may perform step 223 of generating authentication information based on the questionnaire identifier and information on the respondent. The server 210 may create one piece of authentication information by merging the questionnaire identifier and information on the respondent. However, the present invention is not limited thereto, and the authentication information may individually include a questionnaire identifier or information about a respondent.

The server 210 may perform a step 224 of encrypting the authentication information. Various methods can be used for encryption. The authentication information may be information through which a human can intuitively understand a meaning. However, encrypted authentication information may not be intuitively understood by humans. In addition, the server 210 may obtain encrypted authentication information including data for determining whether the authentication information is authentic or not by using a checksum or the like. When there is a checksum, since the values included in the authentication information must satisfy a specific value, it is possible to prevent the respondent from responding to the questionnaire by arbitrarily modifying the encrypted authentication information.

The server 210 may perform step 231 of transmitting the encrypted authentication information to the responder terminal 260 . The responder terminal 260 may include a PC, a smart phone, a laptop computer, or a tablet. The responder terminal 260 may have a program for the questionnaire installed.

The server 210 may transmit a URL or QR code for accessing a web page for a survey to the responder terminal 260 together with the encrypted authentication information to the responder terminal 260 . The server 210 may transmit the URL or QR code using SMS text or email.

The responder terminal 260 may access the survey web page of the server 210 using the URL. For example, the responder may select a URL or QR code displayed on the responder terminal 260 . The responder terminal 260 may transmit a signal requesting the survey web page to the server 210 .

When the responder terminal 260 transmits a signal requesting the survey webpage to the server 210 , the responder terminal 260 may perform a step 232 of transmitting the encrypted authentication information to the server 210 . .

The server 210 may perform step 225 of restoring the encrypted authentication information. Also, the server 210 may perform a step 226 of determining whether the responder terminal 260 is a legitimate responder terminal based on the restored authentication information.

The server 210 may determine whether the restored authentication information matches the previously generated authentication information. When the restored authentication information matches the previously generated authentication information, the server 210 may determine that the responder terminal 260 is a legitimate responder terminal.

In addition, even if the restored authentication information matches the previously generated authentication information, if the restored authentication information matches the authentication information of the respondent who has already answered the questionnaire, the server 210 may determine that the terminal is not a legitimate responder terminal.

In addition, even if the restored authentication information matches the previously generated authentication information, the server 210 may determine that it is not a legitimate responder terminal when the validity period of the previously generated authentication information or the restored authentication information has passed.

If the responder terminal 260 is a legitimate responder terminal, the server 210 may perform step 233 of transmitting the questionnaire to the responder terminal. The respondent may respond to the questionnaire displayed on the responder terminal. The server 210 may receive the responder's response and store it in a database.

According to the present disclosure, as intended by the surveyor, only the respondent who has received the encrypted authentication information can respond to the survey. In addition, according to the present disclosure, since encrypted authentication information cannot be duplicated, the respondent can respond only once to one questionnaire. Also, according to the present disclosure, a respondent can conveniently perform a survey without a log-in process.

In FIG. 2, a flowchart performed by the server 210 and the responder terminal 260 has been described, but the present invention is not limited thereto. The order of the steps may be different from that of FIG. 2 , and steps may be added or deleted.

3 is a flowchart illustrating an operation of a server or a terminal according to an embodiment of the present disclosure.

If the survey is conducted in a performance hall, playground, or classroom, the surveyor may not be able to limit the number of participants. For example, if the surveyor informs that Sohyang is having a concert, an unspecified number of students and faculty members may attend the concert.

When a survey is conducted on an unspecified number of people, there is a problem in that the surveyor cannot specify the respondent in advance. That is, it may be difficult for a surveyor to conduct a survey to an unspecified number of people. Accordingly, the server 210 or the responder terminal 260 may use the location information of the responder terminal 260 to control so that only people in a specific building or a specific place can respond to the questionnaire.

Overall, the server 210 may create a location area. The location area may include reference location information and a range corresponding to the questionnaire. The responder terminal 210 may acquire location information by using a function (eg, Geolocation API) provided by html5. When the responder terminal 260 accesses the survey webpage of the server 210, the server 210 determines whether the responder terminal 260 is included in the surveyable area based on the location information of the responder terminal 260, and , it is possible to determine whether the questionnaire is possible.

In FIG. 3 , the server 210 generates a questionnaire, and when the responder terminal 260 accesses the server 210 , the server 210 may receive location information of the responder terminal 260 . In addition, if the location information of the responder terminal 260 is not included in the location area, the server 210 transmits a signal indicating that the respondent terminal 260 is not a response target, and that the responder terminal 260 is not a response target. A signal can be output.

Hereinafter, FIG. 3 will be described in more detail as a configuration following FIG. 2 .

The server 210 may perform step 321 of generating the location area of the candidate responder. The server 210 may generate the location area of the candidate responder based on the input of the questionnaire. The location area of the candidate responder may include a reference location and a radius. The reference position of the candidate responder may include a value related to latitude or a value related to longitude. In addition, the reference position may further include a height value from the sea level. However, the present invention is not limited thereto, and the server 210 may use a coordinate system capable of indicating a reference position of a two-dimensional or three-dimensional candidate responder.

The location area of the candidate responder may further include radius information from the reference location. For example, it may be determined within 10 m from the reference position. However, the present invention is not limited thereto, and the server 210 may determine the area within a specific room of a building. An area inside a particular room may be determined as a location where at least one predetermined AP is identified.

The server 210 may perform step 331 of transmitting the location area of the candidate responder to the responder terminal 260 . Step 331 may be performed together with step 231 of FIG. 2 . The responder terminal 260 may receive the location area of the candidate responder and store it in the memory.

The responder terminal 260 may perform step 322 of obtaining location information of the responder terminal 260 . 3 illustrates that the responder terminal 260 acquires the location information of the responder terminal 260 after receiving the location area of the candidate responder, but the present invention is not limited thereto. Before the responder terminal 260 receives the location area of the candidate responder, location information of the responder terminal 260 may be acquired.

When the location information is included in the location area, the responder terminal 260 may perform step 323 of displaying a questionnaire. Step 323 of FIG. 3 may be performed after step 233 of FIG. 2 . The responder terminal 260 may determine whether the location information of the responder terminal 260 is included in the location area of the candidate responder. When the location information of the responder terminal 260 is included in the location area of the candidate responder, the responder terminal 260 may display the questionnaire on the display.

Also, similar to the disclosure of FIG. 3 , the server 210 may perform step 331 of transmitting the location area of the candidate responder. Also, the responder terminal 260 may perform step 322 of obtaining location information of the responder terminal. After step 233 of FIG. 2 , the responder terminal 260 may display a questionnaire. The responder may input a response to the questionnaire into the responder terminal 260 . When the location information is included in the location area, the responder terminal 260 may perform the step of transmitting the encrypted authentication information to the server 210 together with the response information to the questionnaire. When the location information is not included in the location area, the responder terminal 260 may not transmit the questionnaire to the server 210 . In this case, since the server 210 can receive only necessary data, it is possible to prevent processing resources from being consumed to process unnecessary data.

4 is a flowchart illustrating an operation of a server or a terminal according to an embodiment of the present disclosure.

The server 210 may perform an operation 421 of generating the first questionnaire password. The first interviewee password may be automatically generated by the server 210 . The server 210 may generate a first questionnaire password based on the questionnaire identifier. The server 210 may generate the first questionnaire password corresponding to the questionnaire by the random number generator.

In addition, the server 210 may perform step 431 of transmitting the first questionnaire password to the responder terminal. Step 431 of FIG. 4 may be performed before, after, or simultaneously with step 231 of FIG. 2 .

The responder terminal 260 may perform step 422 of receiving the second questionnaire password from the responder. The respondent may receive the second questionnaire password from the questionnaire offline. The surveyor may transmit the first surveyor password generated by the server 210 to the responder as the second surveyor password. The responder may input the second interviewer password received from the interviewer into the responder terminal 260 . The respondent can respond to the questionnaire only when the second questionnaire password is input to the responder terminal 260 .

When the password of the first interviewer and the password of the second interviewer are the same and the location information is included in the location area, the respondent terminal 260 may perform step 423 of displaying the questionnaire. Step 423 may be performed after step 233 . Step 423 may correspond to step 323 . The responder terminal 260 may determine whether the password of the first questioner and the password of the second questioner are the same. Also, the responder terminal 260 may determine whether the location information of the responder terminal 260 is included in the location area of the candidate responder. When the password of the first questioner and the password of the second questioner are the same and the location information is included in the location area, the responder terminal 260 may display the survey already received in step 233 on the display.

In the above description, the case in which the responder terminal 260 displays the questionnaire based on the second interviewer password or the location of the responder terminal has been described, but the present invention is not limited thereto. The responder terminal 260 may display the questionnaire regardless of the second questioner password or the location of the responder terminal. However, only when the password of the first interviewer and the password of the second interviewer are the same and the location information is included in the location area, the responder terminal 260 may receive a response to the questionnaire.

The password of the first interviewer or the password of the second interviewer may have an expiration date. Even if the password of the first interviewer and the password of the second interviewer are the same, when the validity period of the password of the first interviewer or the password of the second interviewer has elapsed, the respondent terminal 260 may not display the questionnaire.

According to another embodiment of the present disclosure, the responder terminal 260 may perform the step of obtaining location information of the responder terminal. The responder terminal 260 may acquire location information of the responder terminal by using the geolocatioin technology of HTML5.

Also, the responder terminal 260 may transmit at least one of encrypted authentication information, location information, and responder-related information to the server. The information related to the respondent may include personal information such as the respondent's age, student number, phone number, e-mail address, address, SNS account ID, resident registration number, name, or gender. In addition, the responder-related information may include information related to the responder terminal, such as a MAC address or serial number of the responder terminal.

The step 226 of determining whether the responder terminal of FIG. 2 is a legitimate responder terminal may further include the following process. If the location information is included in the location area of the candidate respondent, the information related to the respondent does not overlap with the information related to the respondent who has already performed the survey, and the restored authentication information is the same as the generated authentication information, the server 210 responds to the respondent. determining that the terminal is a legitimate responder terminal may be performed. Also, thereafter, the server 210 may transmit the questionnaire to the responder terminal 260 .

According to the present disclosure, the server 210 may determine the respondent of the questionnaire using various conditions. Therefore, only the respondents intended by the surveyor can respond to the survey.

5 is a flowchart illustrating an operation of a server or a terminal according to an embodiment of the present disclosure.

If the survey is conducted in a performance hall, playground, or classroom, the surveyor may not be able to limit the number of participants. For example, if the surveyor informs that Sohyang is having a concert, an unspecified number of students and faculty members may attend the concert.

When a survey is conducted on an unspecified number of people, there is a problem in that the surveyor cannot specify the respondent in advance. That is, it may be difficult for a surveyor to conduct a survey to an unspecified number of people. Accordingly, the server 210 or the responder terminal 260 may use the location information of the responder terminal 260 to control so that only people in a specific building or a specific place can respond to the questionnaire.

In brief overall, the server 210 may create a location area. The location area may include reference location information and range information corresponding to the questionnaire. The responder terminal 210 may acquire location information by using a function (eg, Geolocation API) provided by html5. When the responder terminal 260 accesses the survey webpage of the server 210, the server 210 determines whether the responder terminal 260 is included in the surveyable area based on the location information of the responder terminal 260, and , it is possible to determine whether the questionnaire is possible.

In FIG. 5 , the server 210 generates a questionnaire, and when the responder terminal 260 accesses the server 210 , the server 210 may receive location information of the responder terminal 260 . In addition, if the location information of the responder terminal 260 is not included in the location area, the server 210 transmits a signal indicating that the respondent terminal 260 is not a response target, and that the responder terminal 260 is not a response target. A signal can be output.

Hereinafter, together with FIG. 5, the configuration briefly described above will be described in more detail.

The server 210 may perform step 521 of generating a questionnaire and a questionnaire identifier based on the database. A survey list may be stored in the database. A surveyor may input a topic related to a survey to the server 210 by wire or wireless. Based on the topic selected by the surveyor, the server 210 may automatically generate a survey.

The identifier of the questionnaire may include at least one of the order of the questionnaire, the subject of the questionnaire, the creation date of the questionnaire, or a unique number of the questionnaire. The identifier of the questionnaire may be a unique value for identifying the questionnaire.

The identifier of the questionnaire may have an expiration date. That is, a start time and an expiration time of the questionnaire identifier may be determined. The server 210 may perform the survey from a start time to an expiration time. The server 210 may no longer perform the survey when the validity period has passed.

The server 210 may perform the step of generating the location area of the candidate responder. The server 210 may generate the location area of the candidate responder based on the input of the questionnaire. The location area of the candidate responder may include a reference location and a radius. The reference location may include a value related to latitude or longitude related to the location of the candidate responder. Alternatively, the reference position may further include a height value from the sea level. However, the present invention is not limited thereto, and the server 210 may use a coordinate system capable of indicating a reference position of a two-dimensional or three-dimensional candidate responder. The location area of the candidate responder may further include radius information from the reference location. For example, it may be determined within 10 m from the reference position.

However, the present invention is not limited thereto, and the server 210 may determine the area within a specific room of a building. For example, the server 210 may determine a security identifier (SID) of at least one access point (AP) and a signal strength corresponding to the SID as the location area. For example, when the responder terminal 260 obtains at least one SID and a signal corresponding to the SID, the server 210 may determine that the responder terminal 260 has entered the interior of a specific room.

Optionally, the server 210 may perform a step 522 of generating the password of the first interviewee. The first interviewee password may be automatically generated by the server 210 . The server 210 may generate a first questionnaire password based on the questionnaire identifier. The server 210 may generate the first questionnaire password corresponding to the questionnaire by the random number generator. That is, the first questionnaire password may be randomly generated.

The server 210 may perform step 531 of transmitting the questionnaire identifier to the responder terminal 260 . The responder terminal 260 may include a PC, a smart phone, a laptop computer, or a tablet. The responder terminal 260 may have a program for the questionnaire installed.

According to an embodiment of the present disclosure, the server 210 may transmit a URL or QR code to the responder terminal 260 to the user. The URL or QR code may include a survey identifier. The responder terminal 260 may request a questionnaire from the server 210 based on the respondent's input.

According to another embodiment of the present disclosure, the responder terminal 260 may access a predetermined URL. For example, the predetermined URL may be an address for accessing the questionnaire bulletin board. When the responder terminal 260 accesses a predetermined URL, the responder terminal 260 may receive a plurality of surveys conducted by the server 210 at any time. The responder terminal 260 may select a questionnaire desired by the user based on the user's input. That is, even if the server 210 does not separately transmit the survey identifier to the responder terminal 260 , the responder terminal 260 may respond to the survey based on the user's input.

Optionally, the responder terminal 260 may perform step 523 of receiving the second questionnaire password from the responder. The respondent may receive the second questionnaire password from the questionnaire offline. The surveyor may transmit the first surveyor password generated by the server 210 to the responder as the second surveyor password. The responder may input the second interviewer password received from the interviewer into the responder terminal 260 . The respondent can respond to the questionnaire only when the second questionnaire password is input to the responder terminal 260 . Accordingly, the server 210 may limit the respondent to the person who has received the second surveyor password offline, even if there is no separate process for selecting the respondent.

The responder terminal 260 may perform step 524 of obtaining location information of the responder terminal. The responder terminal 260 may acquire location information of the responder terminal by using the geolocatioin technology of HTML5. The responder terminal 260 may be an environment in which there is no location information acquisition function, or an environment in which the user turns off the responder terminal 260 . When the responder terminal 260 uses the location information acquisition function, an error may occur in the user's location due to different environments of the responder terminal 260 . However, when the geolocation technology of HTML5 is used, the responder terminal 260 can obtain the user's location regardless of the various environments of the responder terminal 260 .

Also, the responder terminal 260 may obtain location information by checking a Security Identifier (SID) of at least one Access Point (AP). The responder terminal 260 may obtain the SID of the AP and the signal strength corresponding to the SID. The responder terminal 260 may acquire the location of the responder terminal 260 based on the SID of the AP and the signal strength corresponding to the SID. Also, the responder terminal 260 may obtain location information of the responder terminal using GPS.

The responder terminal 260 may obtain information related to the responder. The responder terminal 260 may obtain information related to the responder from a memory. Also, the responder terminal 260 may receive information related to the responder from the responder.

The information related to the respondent may include personal information such as the respondent's age, student number, phone number, e-mail address, address, SNS account ID, resident registration number, name, or gender. In addition, the responder-related information may include information related to the responder terminal, such as a MAC address, IP address, or serial number of the responder terminal.

The server 210 may not transmit the URL to the responder terminal 260 . The responder terminal 260 may access the survey web page of the server 210 based on a predetermined URL. In addition, the responder terminal 260 may transmit a signal for requesting a survey web page to the server 210 . In this case, since the responder terminal 260 requests the survey web page from the server 210 at the user's discretion, the server 210 does not need to determine a candidate responder in advance. The server 210 may determine whether the respondent is a legitimate respondent based on the password of the first surveyor or the location information of the respondent.

However, the present invention is not limited thereto. The server 210 may set a candidate responder and transmit a URL for accessing a web page for a survey to the responder terminal 260 . The responder terminal 260 may access the survey web page of the server 210 using the URL. For example, the responder may select a URL displayed on the responder terminal 260 . The responder terminal 260 may transmit a signal requesting the survey web page to the server 210 .

The responder terminal 260 may perform an operation 532 of transmitting information related to the respondent, the second interviewer password, and the responder terminal location information to the server 210 .

The server 210 may determine whether the responder terminal 260 is a legitimate responder terminal based on the respondent-related information, the second questioner password, and the responder terminal location information ( 525 ).

More specifically, if the information related to the respondent does not overlap with the information related to the respondent who has already conducted the survey, the password of the first interviewer and the password of the second interviewer are the same, and the location information is included in the location area, the server ( 210) may perform the step of determining that the responder terminal is a legitimate responder terminal. In addition, when it is determined that the responder terminal is a legitimate responder terminal, the server 210 may perform step 533 of transmitting the questionnaire to the responder terminal 260 .

According to an embodiment of the present disclosure, when the information related to the respondent does not overlap with the information related to the respondent who has already performed the survey, and the location information is included in the location area, the server 210 sets the respondent terminal to the legitimate responder terminal. A step may be taken to determine that That is, the server 210 may not generate the password for the first interviewee. The server 210 may not determine whether the password of the first interviewer and the password of the second interviewee are the same. The responder terminal 260 may not transmit the second questionnaire password to the server 210 .

but. When the server 210 receives a signal indicating that the respondent terminal 260 has not properly found the location, the server 210 may generate the first questionnaire password. When the responder terminal 260 does not properly find the location, the responder terminal 260 may receive the second interviewer password from the responder. Also, the responder terminal 260 may transmit the second interviewer password to the server 210 instead of the location information. When the password of the second interviewer and the password of the first interviewer are the same, the server 210 may perform the step of determining that the responder terminal is a legitimate responder terminal.

According to another embodiment of the present disclosure, when the information related to the respondent does not overlap with the information related to the respondent who has already performed the survey, and the password of the first interviewer and the password of the second interviewer are the same, the server 210 is the responder terminal may perform a step of determining that it is a legitimate responder terminal. That is, the server 210 may not determine whether the location information is included in the location area. The responder terminal 260 may not transmit location information to the server 210 .

The responder terminal 260 may display the received questionnaire on the display. The respondent may input a response to the questionnaire displayed on the responder terminal 260 .

The password of the first interviewer or the password of the second interviewer may have an expiration date. Even if the first interviewer password and the second questioner password are the same, if the validity period of the first interviewer password or the second questioner password has passed, the server 210 may not transmit the questionnaire to the responder terminal 260. have. Accordingly, the responder terminal 260 may not be able to perform the survey. In addition, the responder terminal 260 may request the respondent to input the second questionnaire password within the validity period.

When the responder terminal 260 receives the questionnaire, the responder terminal 260 may display the questionnaire on the display. The responder may input a response to the responder terminal 260 . The responder terminal 260 may transmit a response to the server 210 . The server 210 may store the received response and information related to the responder correspondingly.

According to the present disclosure, as intended by the questioner, only the respondent who has received the second questioner password from the questioner can answer the question. In addition, the server 210 may control to respond only to the respondent in a specific location based on the intention of the surveyor. In addition, according to the present disclosure, since information related to a respondent cannot be used repeatedly, the respondent can respond to one questionnaire only once. In addition, according to the present disclosure, since the respondent does not need to log in separately to answer the questionnaire, the questionnaire can be conveniently performed and the possibility of personal information being leaked is blocked.

In FIG. 5, a flowchart performed by the server 210 and the responder terminal 260 has been described, but the present invention is not limited thereto. The order of the steps may be different from that of FIG. 5 , and steps may be added or deleted.

After registering the questionnaire in the server 210 , the questionnaire may be registered for the subjects in the school. Respondents can participate in the survey in three ways according to the settings of the surveyor. First, the respondent may use the responder terminal 260 to view and participate in the survey list registered in the on-campus survey system, or participate in the survey by using Mail and SMS services. In addition, when a questionnaire is required by an unspecified number of people, the questionnaire may be guided by the questionnaire on the bulletin board, and the respondent may participate in the questionnaire using the responder terminal 260 . When registering a bulletin board survey, the same respondent can repeat the survey several times because it is not a method of conducting a survey after logging in. Accordingly, the server 210 receives information related to the responder from the responder terminal 260 to minimize overlapping. And finally, in the case of an offline survey, the responder terminal 260 allows the data to be uploaded to the server 210 in Excel, so that the data can be managed in an integrated manner. The accumulated survey result data is designed to receive an analysis service through the aggregation operation of the server 210 .

7 illustrates an entity-relationship diagram (ERD) defining roles of users accessing a survey system according to an embodiment of the present disclosure.

A survey is largely divided into a surveyor who fills out survey questions and a respondent who is a target of the survey. A surveyor is a person in charge of survey work and is divided into a person in charge of survey work, a person in charge of each department, and a person in charge of each business group. The person in charge is the person who has all the authority to manage the survey, and manages the monitoring and authority of the survey being executed. The person in charge of each department and the person in charge of each project group should frequently conduct surveys related to their work. In order to generalize this, it is necessary to have the authority to create a questionnaire according to individual tasks and a system to manage the authority according to individual status.

7 is a design model in which the user can access the program by identity and task, and gives the user the right to access the program based on the user's affiliation, rank, and job classification, and gives the person in charge the authority as the person in charge of the survey can be assigned to an individual's work.

The on-campus survey can target the satisfaction of classes, facilities, and services. The survey system divides the survey contents operated by department and business group by CASE, and integrates similar contents to construct a survey template. The template is a generalized survey question, and the server 210 can reduce the burden of the surveyor writing the survey question. In addition, the server 210 may continuously investigate the same content and time-series analysis of the questionnaire items may be possible. However, there may be cases in which a surveyor needs to additionally write a survey question or remove a survey question for a specific issue, and the server 210 may enable addition or deletion of questions even if a template is used.

8 is an embodiment for configuring a template. The curriculum item may include a questionnaire related to the curriculum. For example, the curriculum item may include questions related to before class, during class, and after class. In addition, the server 210 may configure a different questionnaire for each series such as arts and sports engineering colleges in the curriculum items.

The non-experimental item may include a questionnaire related to the non-experimental process. The non-examination items may include questionnaires for evaluation of various special lectures and experiential learning.

The facility item may include a questionnaire related to a facility, such as a library or dormitory.

The integrated item is a survey conducted periodically for all students within the school, and may include a survey to investigate the satisfaction of students in various fields within the school, such as university satisfaction, library use frequency, and major satisfaction.

Referring back to FIG. 2 or FIG. 5 , the steps 221 and 521 of the server 210 generating a questionnaire and a questionnaire identifier based on the database may include the following processes. The server 210 may perform the step of receiving the upper questionnaire classification item selected by the surveyor from among the upper questionnaire classification items. As illustrated in FIG. 8 , the upper questionnaire classification items may include at least one of a curriculum item, a non-curricular item, a facility item, and an integrated item.

Also, the server 210 may perform the step of receiving the sub-categorization item selected by the surveyor from among the plurality of sub-classification items included in the selected upper questionnaire classification item. For example, when a surveyor selects a facility item, a library item or a dormitory item may be included in the sub-categorization items.

Also, the server 210 may automatically generate a questionnaire based on the selected sub-category. As described above, the server 210 according to the present disclosure hierarchically receives the selection of the upper questionnaire classification and the lower questionnaire classification from the surveyor, thereby enabling the surveyor to easily obtain a desired survey template.
