Description

Technical Field

[0001] This invention relates to the field of information query technology, specifically to a low-cost NFC-enabled intelligent information query method and system for workstations. Background Technology

[0002] With the continuous deepening of enterprise informatization, employee information inquiry and management has become an important part of daily enterprise operations. Traditional methods of workstation information inquiry mainly rely on the following approaches: First, identification through static information such as name and position printed on workstation nameplates, which has limited information capacity and cannot be dynamically updated; second, inquiry through the enterprise's internal management system, but this requires employees to log in to the computer system, which is cumbersome and limited by office equipment; third, obtaining information by scanning QR codes, but QR codes are easily copied or tampered with, resulting in low security.

[0003] Near Field Communication (NFC) technology, as a short-range wireless communication technology, has been widely used in access control, payment, and attendance systems. Existing technologies include solutions for applying NFC technology to employee badges or tags, such as smart work tags integrating Bluetooth, NFC, and e-ink displays, which use NFC to achieve functions like access control, dining, transportation, and identity information exchange; and dynamic attendance methods based on NFC security tags, which use mobile terminals to interact with NFC security tags via near-field communication for attendance tracking. In addition, there are technical solutions for deploying passive NFC devices in office areas to achieve office space scheduling and monitoring.

[0004] However, existing technologies still have the following shortcomings: First, there is a lack of solutions specifically designed for workstation scenarios that enable convenient employee information retrieval using workstation name tags; second, existing NFC query solutions generally lack effective mechanisms to prevent malicious querying, making it difficult to prevent information misuse or malicious acquisition; third, different query subjects (such as ordinary employees, department heads, and administrators) have different information access scopes, and existing solutions lack refined hierarchical access control; fourth, existing smart name tag solutions often require active components such as built-in batteries or e-ink displays, which are costly and not conducive to large-scale deployment. Summary of the Invention

[0005] The technical problem solved by this invention: This invention provides a low-cost NFC-linked intelligent information query method and system for workstations, aiming to achieve convenient, secure, and hierarchical query of employee work information by combining passive NFC sensing components with workstation nameplates, while ensuring information security through an anti-malicious query control mechanism.

[0006] The technical solution adopted by this invention to solve the above-mentioned technical problems is a low-cost NFC-linked intelligent workstation information query method, which includes the following steps:

[0007] S1. A passive NFC sensing component is installed on the workstation nameplate. The passive NFC sensing component has a built-in unique identification code, which is bound to the employee's identity information and used to uniquely identify the employee corresponding to the workstation nameplate.

[0008] S2. The query terminal reads the unique identification code via NFC, triggering the query terminal to send a query request to the backend server.

[0009] S3. The backend server calls the anti-malicious query control program to perform daily query count verification and abnormal query threshold verification.

[0010] S4. If the verification fails, the query will be rejected and a prompt will be displayed; if the verification passes, the employee's work information corresponding to the preset permission level of the login account of the query terminal will be returned to the query terminal for display.

[0011] Furthermore, the daily query count verification includes: determining whether the number of queries by the queryer on that day is less than a preset upper limit; if not, then marking it as abnormal and rejecting the query; the abnormal query threshold verification includes: determining whether the number of queries for the same employee on that day reaches a preset abnormal threshold; if so, then marking it as abnormal and rejecting the query.

[0012] Furthermore, the permission levels are divided into three levels:

[0013] Level 1 permissions are the default basic permission level, used for ordinary employee and visitor accounts; the employee work information corresponding to Level 1 permissions is the employee's basic static information.

[0014] Level 2 access is used for department head accounts. The employee work information corresponding to Level 2 access includes the complete work information of employees in this department and the basic static information of employees outside this department.

[0015] Level 3 access is for administrator accounts. The employee work information corresponding to Level 3 access is the complete work information of all employees.

[0016] Furthermore, when a new account logs in for the first time, the backend server automatically configures the permission level to level one.

[0017] Furthermore, the passive NFC sensing component is in the form of a sticker and is fixed to the surface of the nameplate body.

[0018] Furthermore, the passive NFC sensing component is in the form of a card and is fixed in the card slot of the nameplate body.

[0019] Furthermore, the employee work information is provided by the employee information database on the backend server. The employee information database is connected to the enterprise attendance system and stores employee work information and attendance data.

[0020] Furthermore, the backend server also includes a permission level database that stores the permission levels of accounts.

[0021] The present invention also provides a low-cost NFC-linked intelligent workstation information query system, which realizes the low-cost NFC-linked intelligent workstation information query method described above. The system includes workstation nameplates, query terminals and back-end servers.

[0022] The workstation nameplate is equipped with a passive NFC sensing component. The passive NFC sensing component has a built-in unique identification code, which is bound to the employee's identity information and used to uniquely identify the employee corresponding to the workstation nameplate.

[0023] The query terminal is used to read the unique identification code via NFC and send a query request to the backend server in response to the reading operation;

[0024] The backend server is used to receive the query request, call the anti-malicious query control program, and perform daily query count verification and abnormal query threshold verification. If the verification fails, the query is rejected and a prompt is displayed. If the verification passes, the employee's work information corresponding to the preset permission level of the login account of the query terminal is determined and returned to the query terminal for display.

[0025] The beneficial effects of this invention are:

[0026] 1. Low-cost deployment. Utilizing passive NFC sensing components (such as NFC stickers or NFC cards), it eliminates the need for active components like built-in batteries and e-ink displays, resulting in low cost and enabling large-scale deployment at enterprise workstations.

[0027] 2. Convenient and efficient query. Users can quickly obtain the corresponding employee's work information simply by using a mobile terminal with NFC functionality (such as a mobile phone) to bring it close to the passive NFC sensing component on the workstation nameplate, without having to log in to a computer system or perform complicated operations.

[0028] 3. Information security is guaranteed. Through anti-malicious query control procedures, the number of queries per day and abnormal query thresholds are double-checked, effectively preventing information from being maliciously acquired or misused in bulk.

[0029] 4. Tiered and refined access control. A three-tiered access system is implemented, allowing personnel with different roles to access different ranges of information. This ensures both on-demand information sharing and protection of employee privacy.

[0030] 5. Strong traceability. The backend server records every query and marks abnormal queries, facilitating administrator traceability and auditing, further enhancing system security.

[0031] 6. Dynamic Information Updates. The employee information database is integrated with the company's attendance system, allowing for real-time updates of employee work information and ensuring accurate and timely retrieval of data. Attached Figure Description

[0032] Figure 1 This is a flowchart illustrating a low-cost NFC-linked intelligent information query method for workstations provided by the present invention.

[0033] Figure 2 This is a schematic diagram of the structure of a low-cost NFC-linked intelligent information query system for workstations provided by the present invention. Detailed Implementation

[0034] This invention addresses the shortcomings of existing workstation information systems, such as limited information availability, untimely updates, cumbersome operations, low security, high deployment costs, and lack of refined access control. It provides a low-cost NFC-enabled intelligent workstation information query method, such as... Figure 1 As shown, it includes the following steps:

[0035] S1. A passive NFC sensing component is installed on the workstation nameplate. The passive NFC sensing component has a built-in unique identification code, which is bound to the employee's identity information and used to uniquely identify the employee corresponding to the workstation nameplate.

[0036] Specifically, during the system initialization phase, the administrator enters the unique identification code of the passive NFC sensing component at each workstation into the backend server and binds it to the corresponding employee's identity information (such as employee number, name, etc.). After binding, a one-to-one correspondence is established between each workstation nameplate and its corresponding employee.

[0037] The workstation nameplate consists of a nameplate body and a passive NFC sensing component set on the nameplate body. The nameplate body can be made of acrylic board, plastic board, metal board or paper material, and its front is printed with the employee's basic identification information (such as name, position, etc.) for easy daily visual identification.

[0038] Passive NFC sensing components can take one of the following two forms:

[0039] Form 1: NFC Sticker. The passive NFC sensing component is in the form of an NFC sticker, with an adhesive layer on the back, allowing it to be directly attached to the surface of the brand nameplate. This form is extremely low-cost, easy to deploy, and suitable for large-scale, rapid deployment scenarios.

[0040] Form 2: NFC Card. The passive NFC sensing component is in the form of an NFC card. A card slot is located on the main body of the nameplate, and the NFC card is embedded or snapped into the slot. This form offers more secure fixation and is suitable for scenarios requiring frequent movement or high durability.

[0041] Regardless of the form factor, passive NFC sensing components all have a unique and tamper-proof identification code built in, which is bound to the corresponding employee identity information in the backend server.

[0042] S2. The query terminal reads the unique identification code via NFC, triggering the query terminal to send a query request to the backend server.

[0043] Specifically, the user brings an NFC-enabled query terminal close to the passive NFC sensor on the workstation nameplate. The query terminal then reads the unique identifier of the passive NFC sensor via NFC near-field communication. The query terminal then automatically sends a query request to the backend server, carrying the unique identifier and the currently logged-in account information.

[0044] S3. The backend server calls the anti-malicious query control program to perform daily query count verification and abnormal query threshold verification.

[0045] Specifically, after receiving a query request, the backend server first calls the anti-malicious query control module to perform security verification. This includes verification of the number of queries per day and verification of abnormal query thresholds.

[0046] Daily query count verification: Determine if the number of queries initiated by the user (identified by the logged-in account) within the current day is less than the preset limit (e.g., 10 queries / day). If the preset limit has been reached or exceeded, it is considered abnormal, the query is marked, and further processing is refused.

[0047] Anomaly Query Threshold Validation: Determines whether the number of queries for the same employee (identified by the employee's unique identifier) ​​on a given day reaches a preset anomaly threshold (e.g., the same employee being queried more than 20 times / day by different queryers, or the same queryer querying the same employee more than 5 times / day). If the preset anomaly threshold is reached or exceeded, the query is considered anomaly, marked, and further processing is refused.

[0048] Through the aforementioned dual verification mechanism, the system can effectively identify and prevent malicious large-scale information acquisition, ensuring the security of employee information and the stable operation of the system.

[0049] S4. If the verification fails, the query will be rejected and a prompt will be displayed; if the verification passes, the employee's work information corresponding to the preset permission level of the login account of the query terminal will be returned to the query terminal for display.

[0050] Specifically, if the anti-malicious query verification fails, the backend server returns a query rejection message to the query terminal, informing the queryer of the reason for the query rejection (such as "the daily query limit has been reached" or "the query frequency is abnormally high, please try again later").

[0051] If the verification passes, the permission management module of the backend server will extract the employee work information within the corresponding permission range from the employee information database according to the preset permission level of the login account of the query terminal, and return it to the query terminal for display.

[0052] In some optional implementations, the employee information database is integrated with the company's attendance system to store employee work information and attendance data. This allows department heads to access attendance data when needed.

[0053] In some alternative implementations, the default permission level of an account is stored in a permission level database on the backend server.

[0054] In some alternative implementations, the permission levels are divided into three levels:

[0055] Level 1 permissions are the default basic permission level, used for ordinary employee and visitor accounts; the employee work information corresponding to Level 1 permissions is the employee's basic static information.

[0056] Level 2 access is used for department head accounts. The employee work information corresponding to Level 2 access includes the complete work information of employees in this department and the basic static information of employees outside this department.

[0057] Level 3 access is for administrator accounts. The employee work information corresponding to Level 3 access is the complete work information of all employees.

[0058] Specifically, Level 1 (Basic Permissions): This is the default basic permission level. When a new account logs into the system for the first time, the backend server automatically configures the account's permission level to Level 1. Level 1 permissions apply to regular employee and visitor accounts. When a user with Level 1 permissions queries any workstation, they can only obtain basic static information about the employee corresponding to that workstation, including but not limited to: employee name, department, job title, employee ID, and other basic information. This level of permission ensures that regular employees and visitors can identify the person to whom the workstation belongs, but cannot obtain more detailed personal work information, effectively protecting employee privacy.

[0059] Level 2 Permissions (Supervisor Permissions): Applicable to department supervisor accounts. Department supervisor permission levels are configured by the administrator in the backend. When a user with Level 2 permissions queries, if the queried employee belongs to the supervisor's department, they can obtain the employee's complete work information, including basic static information, job responsibilities, project participation, attendance data, etc.; if the queried employee does not belong to the supervisor's department, they can only obtain the employee's basic static information (same as Level 1 permissions). This level of permission satisfies the department supervisor's management needs for their department's employees while preventing unauthorized access to information from other departments.

[0060] Level 3 Access (Administrator Access): Applicable to administrator accounts. Administrator access is configured by the system super administrator. Users with Level 3 access can retrieve complete work information for all employees at any workstation, without departmental restrictions. This level of access is used by system administrators for comprehensive information management and maintenance.

[0061] In particular, the query terminal also provides a function to view historical query records, making it convenient for users to review previous query results.

[0062] This invention also provides a low-cost NFC-enabled intelligent workstation information query system, which implements the low-cost NFC-enabled intelligent workstation information query method described above. The system, as... Figure 2 As shown, it includes workstation nameplates, query terminals, and a backend server;

[0063] The workstation nameplate is equipped with a passive NFC sensing component. The passive NFC sensing component has a built-in unique identification code, which is bound to the employee's identity information and used to uniquely identify the employee corresponding to the workstation nameplate.

[0064] The query terminal is used to read the unique identification code via NFC and send a query request to the backend server in response to the reading operation;

[0065] The backend server is used to receive the query request, call the anti-malicious query control program, and perform daily query count verification and abnormal query threshold verification. If the verification fails, the query is rejected and a prompt is displayed. If the verification passes, the employee's work information corresponding to the preset permission level of the login account of the query terminal is determined and returned to the query terminal for display.

[0066] This invention can be widely applied in office settings of various enterprises:

[0067] Scenario 1: Employee identification and communication in daily office work.

[0068] When an employee needs to contact a colleague at a certain workstation but does not know them, they can use their mobile phone's NFC function to scan the workstation nameplate to obtain the other person's name, department, position, and contact information (depending on permissions), enabling quick identification and communication.

[0069] Scenario 2: Visitor reception.

[0070] When visitors tour the company accompanied by staff, they can scan the nameplates at each workstation with their mobile phones to obtain public information about the employees at that workstation, making it easier to understand the company's personnel composition.

[0071] Scenario 3: Department Management.

[0072] Department heads can scan the nameplate of any workstation in their department with their mobile phones to obtain complete work information for that employee, including job responsibilities, project participation, and attendance data, which facilitates work management and task allocation.

[0073] Scenario 4: System Management.

[0074] Administrators can perform comprehensive information management and maintenance through the system backend, including employee information updates, permission configuration, and anomaly query auditing.
