Aim:

To design Examination Question Paper Leakage Protection System.

 

Working Principle:

The box mechanism will be connected with an RFID reader and a memory module. The Box will be programmed in such a way that only the selected authorized personnel will be able to open it. The authorized personnel will be requested to enter the session password to enable the mechanism to open the box after the smart card is swiped and accepted. After reaching the destination the authorized person will again enter the smart card and enter the password. If the password matches then the destination is reached.

The µC will continuously monitor the status of seal break. If the seal is broken before the password matches the second time then the buzzer is activated and an automated SMS is generated to the concerned authority.
