This document describes a fingerprint-based security system that uses a microcontroller and fingerprint module to open a lock only for authorized users. The system scans a fingerprint and verifies it matches one stored on the microcontroller. If so, it activates a relay that opens the locked system. The fingerprint module can store up to 750 fingerprints and is connected to the microcontroller via a serial port. The system provides security for items like medications, jewelry, and documents without needing passwords.

2. INTRODUCTION
The main aim of FINGER PRINT BASED SECURITY SYSTEM
project is develop a security lock system based on fingerprint scanning. In
this project we are using microcontroller for opening and closing lock
based on finger print which is stored in microcontroller itself so that only
authorized person will access the security lock.
Personal Safes are revolutionary locking storage cases that open with
just the touch of your finger. These products are designed as secure
storage for medications, jewellery, weapons, documents, and other
valuable items. These utilize fingerprint recognition technology to allow
access to only those whose fingerprints you choose.

4. • Here in our project used 5v & 12 v supply used ,12v supply
used for relay driver and 5v used to each other components.
• Here fingerprint module is scan the fingerprint and send to
the microcontroller and verifying the scanned fingerprint with
the stored fingerprint.
• When coming fingerprint matches with the stored fingerprint.
then the Relay is complemented. Also the fingerprint ID is
displayed over the LCD display.
• Now show in the relay is complemented and locker system is
connected with relay so locker is opend.
• It can only be opened when an authorized user is present

5. CIRCUIT DIAGRAM

6.  You can add a fingerprint, Delete a fingerprint and identify the fingerprint.
 To add a fingerprint, just show the finger on the module and press the
ADD key. Now the microcontroller will send the ADD command to the
module and the module will add it into the memory.
 To delete the finger follow the same as above.
 To identify the finger, press the Identify button and if the finger matches
then the Relay is complemented. Also the fingerprint ID is displayed over
the LCD display.
 In this project the fingerprint module from Miaxis Biometrics is used. It
can store up to 750 finger prints on its own memory. It can be controlled
through its serial port.

7. IC AT89S52

8. Features
• Fully Static Operation: 0 Hz to 33 MHz
• 256 byte Internal RAM
• 32 I/O Lines
• 8k flash memory
• Three 16-bit Timer/Counters
• Dual Data Pointer
Description
• The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with
8K bytes Flash memory.
• The device is manufactured using Atmel’s high-density non-volatile memory
technology and is compatible with standard 80C51 instruction set and pin out.

9. FINGERPRINT MODULE

10. • SM630 background highlight optical fingerprint verification
module is the latest release of Miaxis Biometrics Co., Ltd. It
consists of optical fingerprint sensor, high performance DSP
processor and Flash.
• It boasts of functions such as fingerprint Login, fingerprint
deletion, fingerprint verification etc.
• Easy to Use and Expand
• All the commands are simple, practical and easy for
development.
• Low Power Consumption
• Integrated Design
• The size is small. And there are only 4 cables connecting with
controller, much easier for installation and use.

11. APPLICATION
 Personal computer security
 e -commerce / e-business security
 Electronic transactions
 Office security
 Banking and financial systems
 Medical information systems
 ATM, cellular phones, laptops, offices, cars etc.
 Door lock system
 Fingerprint security system in car

12. ADVANTAGES
 It can only be opened when an authorized user is present, so
password or pin is not remembering it.
 most secure and accurate than traditional password
 Password based security system has always the threat of
being stolen and accessed by the unauthorized user ,but
here It can only be opened when an authorized user is
present
DISADVANTAGE
• It’s very costly.
