PREVENTING EXAM PAPER LEAKAGE THROUGH RTCSYNCHRONIZED RFID AND OTP AUTHENTICATION

Abstract

Exam paper leakage poses a significant threat to the integrity of academic examinations, undermining the fairness and credibility of evaluation systems. This paper proposes a novel security system designed to prevent exam paper leakage by integrating Real-Time Clock (RTC) synchronization with Radio Frequency Identification (RFID) and One-Time Password (OTP) authentication. The RTC module ensures strict timing control over exam paper access, while RFID technology provides secure identification of authorized personnel. The OTP mechanism adds an additional dynamic layer of authentication to prevent unauthorized access. Experimental implementation and testing demonstrate that the combined use of RTC, RFID, and OTP significantly reduces the risk of leakage and enhances control over exam paper distribution. This system offers an effective, real-time, and userfriendly solution for safeguarding exam materials in educational institutions
