multilevel security system using smartphone

Multilevel security provided by the combination of three securities which is based on the sequence of (I) Magnetic card reader, (II) password and (III) Smartphone. In this paper we have used a multilevel security system which can be used in Home, Bank Lockers, Government offices, Museum etc. to prevent thefts and hacking of the data. ARM 7 Processor (LPC 2138) is the heart of proposed system. It is a low cost, low in power consumption, compact in size and standalone system. In this system we have used ARM 7 processor which compares the passwords entered by keyboard and received through mobile phone. If these passwords are correct the microcontroller provides necessary control signal to open the bank locker. Buzzer will be turn on whenever entered password is wrong and which will detect the person is unauthorized. Then system will send the same message to Police station using android phone functionality and internet facility.
