Abstract: Question paper leakage is one of the main issues for the students, who suffer from the postponement or cancellation of examination. The compact solution for this problem is ARM processor based examination paper leakage protection system. The question paper comes to the college in an electronic sealed box called ibox. The ibox contains an embedded system that was designed using ARM processor, which contains inbuilt RTC to monitor the ibox. If anyone tries to open the ibox before and after the RFID (Radio Frequency Identification) swipe time duration, the system reports to university authorities by sending an SMS (Short Message Service) through GSM (Global System for Mobile communication) that “some malfunctioning is happening with the ibox”. Before 10 minutes of exam the university authorities sends a unique pass code to the chief examiner of the college. The chief examiner has a valid RFID card from the university and swipes the card. If the card is valid the system acknowledges for the pass code. Chief examiner needs to type the pass code using keyboard. If pass code is correct stepper motor rotates and unlocks the ibox. The system is having two sections of transceivers (A and B). The transceiver A is an embedded system associated with the ibox. The transceiver B is the mobile phone with the university authorities. The present work deals with the software and hardware part.
