1. Secure Fingerprint Bank Locker With Image Capture

2. Introduction As today fingerprint based system provides high accuracy in terms of security. Also there is a high demand for integration of fingerprint matching techniques for making secure authentication systems. Therefore we have introduced this bank locker system which integrates fingerprint reader in it so as to provide a good level of security. The main goal of fingerprint bank locker with image capture project is to provide security with no manual security flaws. The system uses an atmega 328 microcontroller for this purpose. The microcontroller processes data sent by the fingerprint reader to check if user is registered, unregistered users are not allowed access. Controller operates the motors to open the locker door on encountering registered valid users. If the fingerprint does not matches with register fingerprint of user it will shows the error message as unauthorized user and immediately saves the picture in memory card. So, the system is very beneficial for stopping the bank locker robbery by providing security.

6. AT Mega 328 t is a single-chip 28 pin DIP microcontroller created by Atmel in the megaAVR family. It has a modified Harvard architecture 8-bit RISC processor core. Block diagram:-

7. Pin description of ATMega 328 VCC is a digital voltage supply. AVCC is a supply voltage pin for analog to digital converter. GND denotes Ground and it has a 0V. Port A consists of the pins from PA0 to PA7. These pins serve as analog input to analog to digital converters. If analog to digital converter is not used, port A acts as an eight (8) bit bidirectional input/output port. Port B consists of the pins from PB0 to PB7. This port is an 8 bit bidirectional port having an internal pull-up resistor. Port C consists of the pins from PC0 to PC7. The output buffers of port C has symmetrical drive characteristics with source capability as well high sink. Port D consists of the pins from PD0 to PD7. It is also an 8 bit input/output port having an internal pull-up resistor. AREF is an analog reference pin for analog to digital converter.

8. 16×2 LCD module: Alphanumeric LCD display module, meaning can display alphabets and numbersConsists of two rows and each row can print 16 characters.Each character is build by a 5×8 pixel boxCan work on both 8-bit and 4-bit mode.

9. Pin description of 16x2 LCD module Pin1 (Ground/Source Pin): This is a GND pin of display, used to connect the GND terminal of the microcontroller unit or power source. Pin2 (VCC/Source Pin): This is the voltage supply pin of the display, used to connect the supply pin of the power source. Pin3 (V0/VEE/Control Pin): This pin regulates the difference of the display, used to connect a changeable POT that can supply 0 to 5V. Pin4 (Register Select/Control Pin): This pin toggles among command or data register, used to connect a microcontroller unit pin and obtains either 0 or 1(0 = data mode, and 1 = command mode). Pin5 (Read/Write/Control Pin): This pin toggles the display among the read or writes operation, and it is connected to a microcontroller unit pin to get either 0 or 1 (0 = Write Operation, and 1 = Read Operation). Pin 6 (Enable/Control Pin): This pin should be held high to execute Read/Write process, and it is connected to the microcontroller unit & constantly held high. Pins 7-14 (Data Pins): These pins are used to send data to the display. These pins are connected in two-wire modes like 4-wire mode and 8-wire mode. In 4-wire mode, only four pins are connected to the microcontroller unit like 0 to 3, whereas in 8-wire mode, 8-pins are connected to microcontroller unit like 0 to 7. Pin15 (+ve pin of the LED): This pin is connected to +5VPin 16 (-ve pin of the LED): This pin is connected to GND.

11. Advantages It is easy to use and requires no special training or equipment. This system needs fingerprint authentication while operating the bank locker as well as captures the images of person who is handling the locker and saves it in memory card which can be later viewed with card reader to the bank authorized person.
