Specification

Description:FIELD OF THE INVENTION
This invention relates to cybersecurity and educational technology, focusing on a system for secure, remote verification in online coding tests. It leverages dynamically generated QR codes for identity authentication, ensuring that only authorized invigilators can initiate and supervise exams for specific students, thereby enhancing security and integrity in remote assessments.
BACKGROUND OF THE INVENTION
Traditional online examination systems often rely on session keys manually entered by invigilators, a process that is both time-consuming and vulnerable to key leakage. This setup not only risks unauthorized access but also places a significant burden on invigilators to manage keys for each student. As online examinations increase in popularity, especially in educational and certification environments, there is a pressing need for a more secure and efficient method to verify student identity and control exam commencement. This invention addresses these challenges by introducing a dynamic QR code-based verification system. By replacing manual input with automated QR scanning, this system enhances security, streamlines the verification process, and minimizes risks associated with key reuse and unauthorized access, making it an ideal solution for secure remote assessments.
SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention.
This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.
To further clarify advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof, which is illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail with the accompanying drawings.
The invention provides a secure system for remote coding exams that utilizes real-time, dynamically generated QR codes for student verification. Each student session generates a unique QR code containing encrypted session details, displayed on the student's screen. Authorized invigilators use a mobile application to scan and verify these QR codes, matching session keys with central database records. Only verified invigilators are authorized to initiate exams, adding an additional security layer and reducing the risk of unauthorized access. The backend system logs every scanning and verification attempt for audit purposes, offering enhanced oversight and compliance for institutions.

The Real-Time QR Code Verification system is an innovation aimed at enhancing the security of remote coding examinations through a QR code-based verification process. The system includes several key components: a Student Exam Portal, a QR Code Generator, an Invigilator's Mobile Application, and a Backend Database. Each exam session generates a unique session key encoded within a QR code, which appears on the student's screen when the exam session is initialized. This QR code contains critical information, including student identification and course details, encrypted for security.
The invigilator accesses a mobile application designed to scan and verify QR codes displayed on students' screens. Upon scanning a QR code, the app communicates with the backend database, which validates the session key and ensures the invigilator has been assigned to that particular student. Only verified invigilators are allowed to initiate the exam for their designated students, effectively preventing unauthorized access. Additionally, the QR codes are dynamically updated for each session, reducing the risk of key leakage and ensuring that every examination period remains secure.
The backend system records each scanning and verification attempt, storing data in an audit log for later review. This functionality provides institutions with oversight capabilities, helping ensure examination compliance and security. The system's encryption protocols prevent unauthorized QR code reproduction or tampering, further enhancing security. Designed for user convenience, the system minimizes the need for manual input, providing a seamless experience for both students and invigilators, and ensuring that exam integrity is maintained throughout the testing process.
