Abstract
Description
Technical Field
[0001] The present invention relates to the field of data sharing, and specifically to a big data sharing method and system based on the Internet of Things. Background Art
[0002] Data sharing enables users using different computers and different software in different locations to read others' data and perform various operations, calculations, and analyses. To achieve data sharing, first, a unified and legal data exchange standard should be established to standardize data formats, enabling users to adopt the specified data standards as much as possible. For example, countries such as the United States and Canada have their own spatial data exchange standards. Currently, China is intensively researching and formulating national spatial data exchange standards, including vector data exchange formats, raster image data exchange formats, digital elevation model data exchange formats, and metadata formats. After the establishment of this standard, it will have a positive impact on the development of China's GIS industry. Secondly, corresponding data usage management measures should be established, and corresponding regulations on data copyright protection and property rights protection should be formulated. Data usage agreements should be signed among different departments to break information protection between departments and regions and achieve true information sharing. In the prior art, with the continuous development of the information age, information exchanges between different departments and regions have gradually increased, and a large amount of spatial data has emerged on the Internet. Facing various data formats, more people can share data more fully. However, when a large amount of shared data is shared, the shared data may change. When different departments, different users, and different time and locations use the shared data, it is impossible to determine whether it is an outsider, and the data content, data format, and data quality may change, which may cause the leakage of shared data. Therefore, it brings great difficulties to data sharing and seriously hinders the flow and sharing of data. For this reason, a big data sharing method and system based on the Internet of Things are provided. Summary of the Invention
[0003] To solve the above technical problems, the purpose of the present invention is to provide a big data sharing method and system based on the Internet of Things; The purpose of the present invention can be achieved through the following technical solutions: A big data sharing method and system based on the Internet of Things, including a server, which is connected to a data storage module, a verification module, a data management module, and an alarm module; The data management module includes a data access management unit and a data change management unit; The data storage module is used to collect and store university data and share the data by a terminal; The verification module is used to authenticate the identity of the terminal and obtain the permission for data sharing; The data management module is used to manage the data sharing of the terminal and generate an alarm signal; The alarm module is used to receive an alarm signal and process it.

[0008] Furthermore, the process for the customer terminal to obtain the data sharing permission includes: When the client terminal shares the data of the university, a hybrid random number generator generates a hybrid random number on one side and sends it to the client terminal; Set the first generated hybrid random number as a six-digit hybrid random number, where the six-digit hybrid random number is 84bd@*, and rearrange the six-digit hybrid random number as the actual six-digit password and send it to the client terminal; The client terminal receives the six-digit password and enters it, and judges whether the input is accurate, so as to judge whether to allow the teacher to share the data: If the input six-digit password is accurate, the client is allowed to perform addition, deletion, modification, and query on the data of the university; If the input six-digit password is inaccurate, the client is not allowed to perform addition, deletion, modification, and query on the data of the university.
[0009] Furthermore, the preset number of times for the terminal to perform identity verification is three times. If all three verification attempts of the terminal fail, a verification alarm signal is generated and sent to the alarm module.

[0014] Figure 1 This is the schematic diagram of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.
[0016] As Figure 1 shown, a big data sharing system based on the Internet of Things includes a server, and the server is connected to a data storage module, a verification module, a data management module, and an alarm module; The data management module includes a data access management unit and a data change management unit; The data storage module is used to collect and store university data, and the specific process includes: Collect a number of university data, and the university data includes different types of file data; The different types of text data include CSV, XML, and JSON; CSV is the abbreviation of comma-separated values, which is a text file format used to store tabular data. In a CSV file, data is stored as a number of records, and each record consists of a number of fields, separated by commas; XML is the abbreviation of Extensible Markup Language, which is a text file format used to store structured data. In an XML file, data is stored as a number of elements, and each element has a tag and some attributes, used to describe the meaning and content of the element; JSON is the abbreviation of JavaScript Object Notation, which is a text file format used to store structured data. In a JSON file, data is stored in the form of key-value pairs, and each key-value pair consists of a name (key) and a value; The collected university data includes student information data, teacher information data, grade information data, and school information data; The student information data includes student name, age, gender, ID number, contact information, grade class, teacher in charge, student location, and credits; The teacher information data includes teacher name, age, gender, ID number, contact information, class taught, teaching type, and office location; The grade information data includes class, class students, class teachers, class location, and class teachers in charge; The school information data includes the school distribution map and all teachers in the school; The student information data, teacher information data, grade information data, and school information data are interconnected for communication. Multiple information data communicate and interact by calling API interfaces, sending messages, etc.; Send the collected university data to the verification module.
[0017] The verification module is used to authenticate the identity of the terminal, and the specific process includes: After the verification module receives the data, it encrypts the data, generates a device from the server identity code, and sends the generated identity code to the terminal. The terminal inputs the identity code to obtain the permission for data sharing. The server identity code includes the student's name, student ID number, teacher's name, and teacher's work ID number. Among them, the student's name corresponds to the student ID number, and the teacher's name corresponds to the teacher's work ID number. The terminal includes a student terminal, a teacher terminal, and a customer terminal. The customer terminal includes other terminals except the student terminal and the teacher terminal. When the terminal shares the data of this university, it needs to verify the identity. Example 1: When a student shares the data of this university, a device is generated from the server identity code and the generated identity code is sent to the student terminal. When the student terminal shares the data, the student terminal inputs the student's name and student ID number, and judges whether the input identity code is accurate, so as to judge whether to allow the student to share the data: If the input corresponding student's name and student ID number are accurate, the student is allowed to perform addition, deletion, modification, and query on the data of this university. If the input corresponding student's name and student ID number are inaccurate and the identity verification fails, the student is not allowed to perform addition, deletion, modification, and query on the data of this university. Example 2: When a teacher shares the data of this university, a device is generated from the server identity code and the generated identity code is sent to the teacher terminal. When the teacher terminal processes the data, the teacher opens the data and inputs the teacher's name and teacher's work ID number, and judges whether the input identity code is accurate, so as to judge whether to allow the teacher to share the data: If the input corresponding teacher's name and teacher's work ID number are accurate, the teacher is allowed to perform addition, deletion, modification, and query on the data of this university. If the input corresponding teacher's name and teacher's work ID number are inaccurate and the identity verification fails, the teacher is not allowed to perform addition, deletion, modification, and query on the data of this university. Example 3: When the customer terminal shares the data of this university, a mixed random number is generated by the mixed random number generator and sent to the customer terminal. The mixed random number generator is a method of combining multiple independent random number generators to generate random numbers with a longer period and better statistical properties. Usually, the first generated mixed random number is used as the permutation basis, and then another random number generator is used to re-permute the first mixed random number. Set the first generated mixed random number as a six - digit mixed random number, where the six - digit mixed random number is 84bd@*, and rearrange the six - digit mixed random number as the actual six - digit password to be sent to the customer terminal; The customer terminal receives the six - digit password, inputs the six - digit password, and determines whether the customer terminal is allowed to perform addition, deletion, modification, and query of data based on the input six - digit password: If the input six - digit password is accurate, the client is allowed to perform addition, deletion, modification, and query of the data of the university; If the input six - digit password is inaccurate and the identity verification fails, the client is allowed to perform addition, deletion, modification, and query of the data of the university; In the specific implementation process, it should be further noted that when the terminal performs data sharing, its identity needs to be verified, and only after successful verification can the data be added, deleted, modified, or queried. Among them, the number of times the terminal verifies its identity needs to be preset in advance. In the above embodiments; The preset number of times of identity verification is three times. If the verification fails three times, a verification alarm signal is generated and sent to the alarm module to notify the university administrator for handling; The terminal successfully verifies the permission for data sharing and sends it to the data management module.
[0018] The data management module is used to manage data. The specific process includes: The data management module includes a data access management unit and a data change management unit; The data access management unit is used to manage access to the terminal. The specific process includes: After the terminal's identity is successfully verified, locate the position of the terminal to obtain the location information data of the terminal; Install a GPS positioning system; Use GPS to automatically locate to obtain the location information data of each terminal that performs data sharing; Correspondingly store the obtained terminal information data with the identity code input by the terminal in the database; Set the data sharing area as the area of the university; Judge whether the terminal is used within the area of the university according to the obtained terminal location information data: If the obtained terminal location information data is within the area of the university, store the terminal location information data in the database and correspond it with the identity code of the terminal; If the obtained terminal location information data is not within the area of the university, generate a location alarm signal and send it to the alarm module; In the specific implementation process, it should be further noted that the database storing the location information data and the corresponding identity code facilitates the management of the university administrator; If the terminal authentication is accurate and the location information data obtained by GPS is within the area of the university, the terminal can perform operations of adding, deleting, modifying, and querying on the data. Send the shared information data to be added, deleted, modified, or queried to the data change management unit. The data change management unit is used to manage the data during the operations of adding, deleting, modifying, and querying. The specific process includes: When the terminal performs operations of adding, deleting, modifying, and querying on the university data, which causes changes to the university data. To make the changed data clearer, automatically mark the data changes. Set the automatic mark for the shared data changed due to adding data to be red. Set the automatic mark for the shared data changed due to deleting data to be yellow. Set the automatic mark for the shared data changed due to modifying data to be blue. The staff of the university checks the university data and the data added, deleted, modified, or queried to determine if there is any abnormal data: If abnormal information data is found, generate an abnormal alarm signal and send it to the alarm module.
[0019] The alarm module is used to receive the alarm signal and process it. The specific process includes: When receiving the verification alarm signal, generate a "verification failed" signal and send it to the terminal, notifying the terminal that the verification failed and it cannot perform operations of adding, deleting, modifying, and querying on the shared information data of the university. When receiving the location alarm signal, generate a "location not in the area" signal and send it to the terminal and the staff of the university, notifying the terminal that its location is not within the area of the university and it cannot perform operations of adding, deleting, modifying, and querying on the university data. When the staff of the university receives the "location not in the area" signal, they perform positioning based on the location obtained by GPS to check if the terminal is within the country, preventing the leakage of the shared information data of the university. When receiving the abnormal alarm signal, notify the staff of the university to check the abnormal data, find the source of the terminal with abnormal data, and notify the terminal to make modifications.
[0020] In the specific implementation process, it should be further noted that the terminal information data stored in the big data and the identity code input by the terminal are for the convenience of the staff of the university to check the abnormal data, find the terminal, and notify the terminal to modify the data.
[0021] Based on the above intelligent online invigilation system, the present invention also provides a big data sharing method based on the Internet of Things, including the following steps: Step 1: Collect university data and store it, and perform data sharing by the terminal. Step 2: Authenticate the identity of the terminal and obtain the permission for data sharing; Step 3: Manage the terminal during data sharing and generate an alarm signal; Step 4: Receive the alarm signal and process it.
[0022] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
